For some reason, I can't get the Gridview in the Updatepanel to refresh after I've made changes. can someone help?
I'm using the ToolkitScriptManager control and the UpdatePanel.
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:GridView blah... [code]....
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>
I have a page with some value like this:
[URL]
what I want to do is when the user enters values on the page I want to be able to change "valueA" and "valueB" in the URL without redirecting, refreshing or posingBack. Does anyone know how to do this?
I'm trying to refresh update panel via Javascript:
__doPostBack("<%=upMyPanel.ClientID %>", "");
But somehow its controls are all empty. On other hand they are all filled when I click any trigger control.
How can I fix this?
I have an asp.net webpage with an modalpopupextender inside of an updatepanel. When I click Ok on the popup, I can get the textbox values from the popup just fine, but the DropDownLists have the old/default value, not the new value I have selected for them.
All the controls on the popup are set to enableviewstate = true, and autopostback = false (I just want to make the trip to the server when I click the ok button, not every time I change the value of the popups).
Here is the relevant code

I have a simple ListBox and a Ajax File Upload control. I have these controls within an Update panel. But I cannot get the ListBox to update upon uploading a new file.
View 4 RepliesI am dynamically ading the following to an UpdatePanel
Tab control which has X# of Tabs, each Tab has a various labels and a Rating Control.
When the user hits the Rating contro, the RATING_Changed fires and runs a stored Proc to update the DB. I want the Panel to then display the newest information back from the DB. I can't seem to get the last part to work. I'm still learning .NET so i may have missed somethign easy, but i've tried setting AutoPopstback, using Triggers, etc.
The DB Update does take place but the NEW contents are not displayed

I am facing a critical condition wherein I have a web page and a User control within it.I need to set the value of two labels in the user control using values collected on the server side.However whatever I do on the server side or client side I do see on the webpage although I can see in the code that it is being set.So Now I am just sending the value from the server side and setting it on the client side.I am sending from server side using,
if(rowcnt > 0 && rowcnt1 > 0 && (selectedh != string.Empty))
ScriptManager.RegisterClientScriptBlock(this.updMainTable, typeof(string), "test1", "showRehabMain('"+val+"')", true);

I'm trying to update just the bing map I am using in an UpdatePanel because it takes a few seconds load. I need to call a javascript to refresh my pushpins though when the refresh is complete.
View 7 RepliesI have 2 ddls (cascading that does not use the AJAX cascading ddl) within an updatepanel within an EditTemplate field in a DetailsView. Changing the first ddl causes a full page refresh (this is the problem I am trying to overcome), but changing the second ddl does not. The second ddl is set to autopostback as well because of other logic (if user selects value "Add" a modal pops up to add a new option to the database).
Now the first, does a call out to a class to handle setting the list of values for the second...that is the only difference I can tell between the two, but I wouldn't think that would cause the issue because it is within an updatepanel.
Here's the code:

On Selected Index Change code for each
For the First:

For the Second:
Protected Sub ddlModel_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Dim ddlModel As DropDownList = dtlBikes.FindControl("ddlModel")
Dim ddlMfg As DropDownList = dtlBikes.FindControl("ddlMfg")
If ddlModel.SelectedValue = "Add" Then 'Add New Record
txtDDLName.Value = "ddlModel"
txtDtlsViewName.Value = "dtlBikes"
txtItemType.Value = "BikeModel"
txtParentID.Value = ddlMfg.SelectedValue
txtNewItem.Text = ""
txtNewItem.Focus()
lblNewItem.Text = "Enter New Model:"
modInsertItem.Show()
End If

I have a Gridview which is inside a Updatepanel which is updated through a Timer Control every 5 seconds.
So every 5 seconds I get new data in the rows. I am facing an issue in which I want to display the whole mult-line content of my Textbox(es).It displays fine but the modal window disappears after the UpdatePanel is updated.
How do I display this pop-up modal window and make it stay while the UpdatePanel continues to update the rows in the background?

I have seen this discussed in number of topics, but so far nothing to address my specific issue. I want to display the page the client, and then trigger an updatepanel refresh that will populate with data that takes 3-4 seconds to load (the rest of the page loads very fast). At the same time I want to display "...Loading..." text using UpdateProgress control.
Everything is working below in the sample code. However, UpdateProgress will not display unless the button is actually clicked by the user. In real production scenario I would hide the button. To invoke the immediate UpdatePanel refresh I trigger the click via Javascript. I have also tried "__DoPostBack" without success.

I got strange behaviour here. My environment is VS.Net 2008 Team server and I tried to use updatepanel but failed.
[Code]....
When I clicked the button, I expect Label3 inside updatepanel to be updated and Label2 remained the same, AND of course without page refreshing flick. But the result is page is completed refreshed and both labels are updeted.
Here is the code. On button click it should perform async refreshing. Instead it does a full page postback.

I want to make auto partial page refresh in asp.net. There is UpdatePanel but it sends too much data. So I've found that I can make a webservice and call it by the JavaScript code. But I don't know how to call webservice automatic. There are many examples showing how to call webservice by the button click event:

I am using AJAX extension in visual studio 2005. First of all i am created a Web custom control which contains Dropdown list. I have also set AutoPostBack="true" for getting its SelectionEventChange event.
I am added this web control on another page inside a UpdatePanel.(i added dynamically on another page).
MyControl = (MyControl) LoadControl("MyControl.ascx")
My problem is when i select the values from dropdown it refersh my whole update panel.

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.
View 3 RepliesI have a page under MasterPageFile, I try the following code into my page; However, I can't see the update progress content when the page refresh.

I've implemented a Wizard in which most steps are UserControls. One of these steps contains a DropDownList and a RadioButtonList. Depending on the item selected in the DropDownList, some items in the adioButtonList are disabled or enabled via a callback. This works fine.
Then I added a ToolkitScriptManager to the page (EnablePartialRendering="true") and wrapped the controls in this particular step in an UpdatePanel's ContentTemplate. Running inside of VS2008, the appropriate radio buttons are disabled or enabled as expected in response to changes in the DropDownList without a full page refresh. It feels much more response and looks slick.
Then I deploy to the test server and suddenly the partial-page refresh is gone, the whole page is redrawing as though the script manager and UpdatePanel hadn't been added.
I've tried several variations on this, always with the same result. For instance - I moved the DropDownList outside of the updatePanel and added an AsyncPostbackTrigger for the DropDown's SelectedIndexChange event. No change - works in VS2008 but not on the server. - I added ChildrenAsTriggers="false" UpdateMode="Conditional" to the UpdatePanel, both with the DropDown inside the UpdatePanel and outside the UpdatePanel. No change - works in VS2008 but not on the server.
I am using AJAX TabContainer control with following settings. When I change a tab the postback happens and whole page refreshes. Because AutoPostBack="true"> . To AJAxify the behavior, I added UpdatePanel around it but still the page is refreshing. The control need to go to server because user controls contains some grids which need to be populated.

I have an annoying problem when I'm developing in Visual Studio 2010. I am using an UpdatePanel in my .ascx file like this:
<asp:updatepanel id="upStuff" runat="server">....</asp:updatepanel>
in my control.ascx.designer.cs, the update panel is being defined like this:
protected global::System.Web.UI.WebControls.WebParts.updatepanel upSettings;
this produces the error:
"The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)"
The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to system.Web.UI.WebControls.Webparts.updatepanel. I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5.
