Forms Data Controls :: Refreshing Datalist In Updatepanel?
Sep 22, 2010
I have a datalist. When a user clicks a button in the datalist I change some properties and then want to refresh the datalist. However, the code below doesnt seem to refresh the datalist. 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.
In bold I've marked where I want to refresh the datalist
<asp:UpdatePanel ID="upnlPhotos" runat="server">
<ContentTemplate>
<cc1:AsyncFileUpload ID="afuPhoto" runat="server" />
<asp:DataList ID="dlPhotos" DataSourceID="dsPhotos" DataKeyField="id" RepeatColumns="5" RepeatDirection="Horizontal" GridLines="None" runat="server" >
[Code].....

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:
[Code]....
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.

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?

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:

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.

I have a page that displays data depending upon the date range entered by the user into two textboxes. I have added the CalendarExtender control from the Ajax Toolbox to each of these two textboxes, and I would like the associated updatePanel to refresh with new data whenever either of the two dates is changed. Sounds simple enough, but I have not been able to manage it so far.

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.

I have a very strange problem here I am using a GridView which shows nothing the the page loads for the first time. But when user selects something from the dropdown above, it DataBind()s against whatever is returned by the stored procedure.
If ran the code in debug mode, it showed that gvMyGrid.Datasource had data in the list returned by SP.Then I did gvMyGrid.DataBind(), it keeps the same empty view.I tried one more thing, I bound the grid when the page loads for the first time to one of the default values returned. It showed the data but when I changed the dropdown selection, it kept the same data.

I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?

I am trying to implement a GridView. This GridView needs to allow users to read and update data from a single table. The data in the GridView is the population for a city/state. Please note the use of the DISTINCT as some cities in a state have multiple postal codes. Regardless, to edit this information, I'm trying to use the following GridView:
[Code]....
The information is displayed as I would expect. My problem is with editing. When I click the "edit" link, a TextBox associated with the population is displayed as expected. When I click "update" though, my change fails to persist. I fired up SQL Profiler and found that the data in the Grid is being refreshed before the UPDATE statement is being sent. Because of this, the original value is being sent. what am I doing wrong? I just need to update the Population value of the cities with the value entered by a user.

I am using a Gridview inside an UpdatePanel. I am using the RowCommand method to call my code to delete the record. The gridview is bound to a <list> collection. I am unable to get the Gridview to postback / refresh after the users deletes a record; however, if I refresh the page in the browser and the page loads, it obviously is gone. I have searched quite a bit on this where others are having problems but nothing they did work for me, so I was hoping someone could review my code and let me know what I am doing wrong.
Here is my ASPX:
[Code]....
Here is my C#
[Code]....
When I step through the code, the postback happens and then my delete code is called, so once the delete code happens, the page is already finished loading, which seems to be my problem.
