AJAX :: GridView In UpdatePanel Not Refreshing?


Here is the setup:

VS 2008Update PanelIn the update panel, is a gridview, and an asp:panel that contains some other controls, including the button I want to trigger the update of the gridviewThe gridview is tied to a sqldatasource, although I have tried multiple methods to get the data and all failed

Here is the problem:

User logs in and fills out the top part of the form.  That submits some data to a table, returns the ID of the row submitted and makes an asp:panel visible (panel.visible=true).  This update panel exists inside of the UpdatePanel.  The user clicks a drop down list and selects a name.  When this happens, another panel becomes visible, using the same process, to allow the user to enter data about the name they selected.  So far, everything works.

What Should Happen next:

User clicks "Add" buttonDatabase is updated with the data enteredDatasource refreshesGridview refreshes - It is not visible at load because there are no records for it to show.

What Actually Happens:

User clicks "Add" button Database is updated with the data entered - This has been verified Datasource should update, but not sure it is Gridview does not show.

Here is the code snippet for the Update Panel:

AJAX :: GridView Not Refreshing In UpdatePanel After Selecting LinkButton?
This GridView contains a TemplateField with a LinkButton that displays a text value. When the link button is clicked, the code behind needs to capture the text value of the button, and then refresh the GridView with an asynchronous postback within the UpdatePanel and display the updated output.

The post-back event is occurring, and I'm able to capture the event in Visual Studio 2010 debugger.  But, the screen contents do not change after this event occurs.  No exception gets thrown, at least from what I can see in debugger.

Portions of the sanitized code appear below.  The GridView actually appears on a page that contains 2 dropdown lists and 2 other GridViews.  There is just one UpdatePanel on this page.

[Code]....

This is in the Code-Behind.

[Code]....

I can put a break point in the above method, and it is captured when the lnkHostName button is clicked.  Stepping through the lnkHostName_Click() method, the ReloadPage() method successfully runs, then executes this method:

[Code]....

This runs successfully, and the DataSet which gets returned contains 1 row of data rather than several rows.  This is what I expect to happen. Once the filter is selected in my test case just 1 row should get returned. The problem is that I don't see that output refreshed on the screen.  The grdProcesses gridview continues to display the original dataset of several rows, rather than just one row of data. To additionally test this, I tried setting the visibility of grdProcesses to false within this method when the HostName had a value. Again, this ran without an error, but the GridView was still visible. And I also tested by updating the contents of a label with the HostName value. The new value was never displayed in the label. I also tried putting the lnkHostName button into the triggers, ala:

[Code]....

But the following exception gets thrown when that button is added, "A control with ID 'lnkHostName' could not be found for the trigger in UpdatePanel 'upMain'."

What's frustrating is that everything appears to run smoothly in debugger.  But in reality the expected output never gets refreshed on the screen.  Perhaps I need to use an alternate trigger in the AsyncPostBackTrigger.  I'm open to using a command button or some other artifact.

AJAX :: UpdatePanel Keeps On Refreshing The Page?
It keeps on refreshing the page I'm using framework 4 (VS 2010 RC1Release).

AJAX :: Refreshing Controls Outside An UpdatePanel?
I have an UpdatePanel with some controls, and a tree control outside of the UpdatePanel. The tree control is huge (~4 MB) hence I don't want to refresh the tree on postbacks from within the UpdatePanel.

Main settings:

Everything is working great, except during one of the PostBack from within the UpdatePanel, I want to refresh the tree. This just does not seem to be possible.

AJAX :: AutoPostback In Repeater In UpdatePanel Is Refreshing The Page?
I've got a TextBox with AutoPostBack="true" and OnTextChanged property set.

The textbox is located inside a Repeater, which in turn is located inside an UpdatePanel.

Problem is - whenever the TextBox postsback, the whole page gets reloaded, instead of the UpdatePanel only.

Here's how the thing looks:

[Code]....

Interesting thing is, if I take the TextBox out of the repeater, it refreshes only the UpdatePanel. So is if I put a Button inside the repeater - only the UpdatePanel gets refreshed. But whenver I place an AutoPostBack-ing control inside the Repeater, the whole page gets refreshed.

[Code]....

UpdatePanel Not Refreshing In Accordion?
I'm using MS AJAX's accordion control. It works fine normally, but I can't seem to get it to work with an UpdatePanel. My layout is like this:

<div id="accordion">
<div><a href="#">Header1</a></div>
<div class="acc_content">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<asp:button id="btnToggle" runat="server" text="toggle"/>
//my repeater contents go here. The buttons within the repeater cause a postback, but changes cannot be seen unless the page is manually refreshed (since the updatepanel doesn't refresh)
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnToggle" EventName="click" />
<asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="click" /> //this button is outside the updatepanel
</ContentTemplate>
</Triggers>
</asp:UpdatePanel>
</div>
<div><a href="#">Header 2 </a></div>
<div class="acc_content">
Content of the second pane
</div>
</div>

There are postbacks occurring when I click the buttons, but the updatepanel never refreshes or updated. I tried adding UpdatePanel1.Update() in the code-behind for each postback event, but no luck. Any ideas as to why this is happening?

AJAX :: Gridview Within Updatepanel Not Triggering Gridview Outside Of Updatepanel
I have a page that has a updatepanel around a gridview control that is within my modalpopup. So you land on the page, there is a link that when clicked will open the model popup.

Forms Data Controls :: Refreshing Datalist In Updatepanel?

Once I reload the entire page (which I dont want) the changes are visible in the datalist. I also tried setting the updatemode of the updatepanel to "Conditional" and update manually in the dlPhotos_ItemCommand, but that doesnt work either.

AJAX :: How To Select Gridview Using UpdatePanel
I have a an UpdatePanel that binds data to a Gridview. Within the gridview I have a select button that will pass the selected id to another Gridview that uses an UpdatePanel. The issue I have is when I select a row in the first gridview one of 2 things occur.

1.) The selection does happen until the Timer refreshes. For instance if I select row 1 in Gridview1, I don't see the 2nd Gridview until the Timer refreshes after 30 seconds.

2.) The selection will happen right away IF I click on the Select button twice. (Don't want this...)

Is there something I'm missing that is causing the first click to the gridview to not select that row immediately? What really gets me is if I put a breakpoint on the Gridview1 SelecteIndexChanged, it fires right away and if I walk through the code it selects it right away.

AJAX :: UpdatePanel AsyncPostBackTrigger And Gridview Not Updating?
I have a very simple application that works almost all the time. I am using an UpdatePanel. My script manager is configured to enable partial rendering. My UpdatePanel is configured for conditional update mode. My asynchronous trigger is a timer that runs every 3 seconds. I track unhandled exceptions in the database. I am not getting any unhandled exceptions. Nor am I getting managed exceptions. Now, I had two users side by side running the application today. I had one record in the data queue. The first user did not get updates; her grid did not update. The second user did get updates. The only difference was that the first user was logged in for a long period of time. The second user logged in just before the test. I reviewed the IIS log file and both users were polling the page every 3 seconds for the same data. So why didn't the first user's grid update? The code follows.

<asp:ScriptManager ID="ScriptManager1" runat="server" AsyncPostBackTimeout="30" EnablePartialRendering="true"></asp:ScriptManager>

[Code]....

In my code behind I have the following timer logic. [Code]....

AJAX :: Using Textbox Onchange To Trigger Updatepanel / Gridview?
How can I get a gridview (that is inside an update panel) to update/filter whenever something it typed into a related textbox outside that panel..( possibly in another update panel)?

As in Google. When you start typing, it starts autocompleting for you by looking up words in the background using the text you've typed.

I want, in effect, for a user to start typing in a textbox (say "Order #" textbox) and each time a character is typed, to trigger an update to a gridview that has a 'search param' in it's SQL Datasource SP that plugs the textbox's text into the where clause of the select inside the SP...

AJAX :: GridView Paging Not Working Inside UpdatePanel?
I have a GridView inside an update panel, with AllowPaging property set to 'true'. Although the links 1 and 2 for the two pages of the GridView are displayed at the bottom of the gridview, clicking on 2 doesn't take me to the second page, atleast not visibly.

Once i've done this, although the first page seems to be displayed still, selecting a row displays details of the row on page 2 at the same position. So i'm actually on page 2, but the display somehow doesn't seem to have refreshed, and since link 1 is still highlighted, I cannot get back to page 1 of the GridView without refreshing the whole page.

The paging works fine if I remove the Update Panel for the GridView.

FileUpload Control Inside Gridview (ajax Updatepanel)
I've got a fileupload control inside of a gridview so that each row (item from the database) can have an attachment associated with it. I've got a button next to the fileupload control (besides the default browse... button to select the file) to actually take the file and upload it to a file server. This works great if I use this button "Upload". However, underneath my gridview I have another imagebutton that is outside of the gridview, its just sitting on the form / page. The idea of this "Update" button is when end users make changes to the grid I can simply loop through the grid and update the values they have entered to the database. This also works great.

Now here is my issue assume a user has 3 rows in the grid view. On 2 of these rows he decides to add an attachment but he never clicks the "Upload" button he only uses the standard browse button to select the file. Now instead of clicking the "Upload" button that is on the grid view he ends up clicking the "Update" button outside of the grid thinking that it will save his attachments. So I decided to write code to grab the fileupload control from the grid using .FindControls("NameOfFileUploadControl") in my Update button loop where I loop through all the rows. Then I check if myFileUploadControl.HasFile property to see if there exists a file and if there does upload the file then continue with the code.

The issue is when I click this "Update" button .HasFile always returns false even though I can see the text string of the path in the fileuploadcontrol textbox (the standard one next to the browse button). Is it because this goes back to the page load event and checks if it is a post back? What causes this and how can I fix it? Im adding some code because im still confused with this

Protected Sub SaveGrid()
For Each Row As GridViewRow In Me.gvLineItems.Rows
Dim f As FileUpload = CType(Row.FindControl("fuAttachment"), FileUpload)
'todo: this part is not working
If f.FileName.Length > 0 Then 'returns 0 always
'this returns 0.
end if
if f.HasFile() then
'this also returns false
end if
Next
End Sub

This method gets called on a click of a button. The fileupload control is in an of a gridview that is wrapped inside of an UpdatePanel:

<asp:FileUpload Width="90px" Font-Size="xx-small" ID="fuAttachment" runat="server" />

AJAX :: GridView Results In UpdatePanel Appending After Update?

//Bind data source
GridView1.DataSource = ds;
GridView1.DataBind();

Each time the I click the button, a new Gridview is rendered back to the browser in my updatePanel.  The problem is that each new Gridview (html) is appended to the last one to the right of it. 

Does anyone know how to prevent the gridview from appending? I would like it to only show the last Gridview data values.

AJAX :: Cursor Disappears After Editing GridView In An UpdatePanel?
I have setup a gridview within an update panel, which resides in a tabcontainer.  After I edit any of the rows within the gridview and hit "update" the page reloads and I am no longer able to edit any of the text boxes in the other tabs, and if I attempt to insert or edit a row within the same gridview I'm not able to edit those either.  That said, when I hit the tab key a couple of times the cursor appears and I'm able to proceed with editing.  Based on the number of times I hit the tab button, it appears that the cursor was inside the textbox I clicked, though it wasn't visible and I simply wasn't able to enter any text.

I've been trying to setFocus on a specific field after any of the grid updates, also tried setting the cursor using ScriptManager.GetCurrent(Me).SetFocus(Me.Control) with no luck.

AJAX :: How To Use Updatepanel With Gridview To Hide It On Initial Page Load
I have a gridview whose data is populated from an object datasource. Now since this data loading happens on initial page load , i want to render the other two controls  (Text box and a Button) on the page and show "Loading" text or image in place of the gridview till all the data is retrieved. I read around the forums and saw that to make this work I need to use UpdatePanel, ScriptManager and UpdateProgress controls. 

I have embedded the gridview in the ContentTemplate Tags of update panel . I also associated the ID of the panel to the update progress control. Now only thing i'm left with is how to make the initial page load trigger the gridview after the whole data is retrieved.

here is the code i got so far

Ajax - Gridview Paging Doesn’t Work Inside UpdatePanel
Altough questions somehow similar to this have been asked for a number of times, but the question is still unsolved. Here is the question: I have a gridview which is contained in a tab container ajax control which itself is inside an updatepanel. Gridview works excellent and its corresponding methods are fired accurately, but when I enable paging, (e.g.) after I click on page 2, the gridview hides itself. here is my PageIndexChanging method:

protected void GridView1_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
GridView1.PageIndex = e.NewPageIndex;
GridView1.DataBind();
UpdatePanel2.Update();
}

AJAX :: Unable To Update Gridview Date From Database In Updatepanel
My problem is that I have tried to update my gridview which is inside my updatepanel but the data in the gridview does not update or change when I change the data in my database.

I have used the basic method of using timer to change the label like this Label1.Text = DateTime and with trigger <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />. Timer is  <asp:Timer ID="Timer1" runat="server" Interval="1000" Enabled="true" OnTick="Timer1_Tick"> .

<Triggers>

AJAX :: UpdatePanel And GridView (Input String Was Not In A Correct Format)?
I have implemented a custom gridview paging method using the pagertemplate tag. The source code is the following: 

[Code].... 

In the code behind file the row command event:

[Code].... 

The odd in that situation is that only one ImageButton throughs an error, the imgPrevious. The other three (first, next, last) work ok.When I click the previous button I get a popup message box 'Input string was not in correct format'.As you can see in the rowcommand event there is no much difference in coding amongst the other three image buttons.While debugging rowcommand event e.CommandArgument holds the correct value as well as intCurIndex.When RowCommand event ends it throughs the message box and processing stops.I can't figure out the reason, I tried tracing but I can't find any clue since it seems that it looks like a bug on Ajax UpdatePanel.Does anybody having similar problem, found a way to trick around that issue?
