AJAX :: UpdatePanel Doesn't Update Another UpdatePanel?
Jan 20, 2011
I have two updatepanels on my site (upanProfileSearch and upanMemberList). When I hit the button in the upanProfileSearch it should bind the Data Items in the gridview in upanMemberList and here make a RowFilter on the text in upanProfileSearch. When I make a run to curser, I can see, it happens. It makes a RowFilter. but it doesn't update the gridview. Can anyone tell me why it doesn't update? I have UpdateMode="Always" and RenderMode="inline" on both UpdatePanels.

i have a website with three UpdatePanel Control and inside of each UpdatePanels has ONE Gridview and a SqlDataSource Control.
all gridviews are connected to its own SqlDataSource Control. so technically when i run my website all gridviews automatically get their data from their respective SqlDataSource Control and display them accordingly.
but what i need to do is instead of letting all the update panels to load each gridview their data upon Onload event, i need the updatepanel to update on queue, (Technically changing the UpdateMode to Conditional does not solve my problem.) there will be an event which will trigger the updatepanel to update later.

I have a pretty standard update panel. In the update panel are radio buttons that trigger the update panel to change it's view (list or grid) based on which radio is selected. This works great in every browser except IE8. IE8 doesn't seem to want to update the height of the panel when it's refreshed causing the content are to stay rather large or to not be large enough.You can see it here:http://ccctest.insidehcc.com/Crossroads/Connect/Community-Groups/Video-Library/Spiritual-CPR

i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?
Complete code is below:

I am trying to trying to setup an updatepanel to update every X seconds, the problem is I don't want the control to actually refresh unless there is new data. So I currently have a child updatepanel in a parent UpdatePanel, the child updatepanel gets refreshed by a timer. But I can't seem to find a way to trigger the parent panel to update. Again, only when certain conditions(data changed) are met.
Sample Code:

I have a GridView in an UpdatePanel and in the code behind I bind to a Datatable and call the GridView's Sort method:
gvUsers.DataSource = dt;
gvUsers.DataBind();
gvUsers.Sort("DateOfBirth", SortDirection.Descending);
However, this doesn't sort the records. I have the Sort event as an asynch trigger for the grid.

I'm just getting into AJAX (little late I know) and am walking through some of the tutorials on the ASP.NET/AJAX site. One thing I've noticed is that I cannot get the UpdatePanel to work (meaning, prevent a full postback of the page) in the ASP.NET Web Site template. I can use the EXACT same markup, code, and web.config in the AJAX 1.0-Enabled ASP.NET 2.0 template and everything works as expected.

I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I have an UpdatePanel on the page which I'd like to trigger using javascript.First of all my code perfectly works if it's in a website not being inheriting from a masterpage. Now when you put exactly the same code into a website which inherits from a masterpage, the UpdatePanel wouldn't get fired anymore.

I cannot use asyncFileUpload as it has too many restrictions which doesn't meet our requirement.
I'm able to add a updatepanel trigger to force the Button1 to perform a postback. after the file uploaded, I need to use a timer to do different tasks and return messages back to client with the timer. That is all fine.
However, when one upload is finished. I try to do it again. The FileUpload1.HasFile is "false". I don't know why. if I remove the timer, at the second time, the HasFile is "true". I think there must be something in the timer and disable the Button1's postback.

Code Behind :

In this case, I can't show value myMethod at code behind to aspx file where this method is called.
If I use postBackTrigger in upControl updatePanel then the method(myMehod) will show on upShow updatePanel. But the updateProgress doesn't work.

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();
}
Why paging causes gridview to stop working correctly? What can I do?

I've a Detailsview that contains an updatepanel.A button is pressed within the panel and a window is displayed containing a gridview list.The user selects an item from the list, the window closes and the selected gridview item is placed in "tbResourceID" My problem however comes when the user goes to click insert the validator doesn't fire. I'm guessing this is something to do with the updatepanel isolating the validator.... my code is shown below!

I have a dropdownlist, that causes a postback. On the SelectedIndexChanged event, is it possible to force a placeholder that is within a different UpdatePanel to change it's visibility?
For example, when the SelectedItem.Value of DropDownList1 is "1" then show Placeholder1, otherwise hide it.
What I am most interested in is how to configure the UpdatePanels to allow this.

I have a web user control with one updatepanel (pnlUpdate_2), some controls and one apply button. I display the web user control as a modalpopup in my default page. In my default page i have an updatepanel (pnlUpdate_1) with a gridview and I modify that gridview with the apply button of the web user control. The web user control is for made a custom search of the gridview data. I have a problem with both updatepanels. If I set the updatemode as always in one of them (pnlUpdate_1) and the other as conditional (pnlUpdate_2), the pnlUpdate_1 make a postback in the pnlUpdate_2; I'm not an expert on this but I think that's why the pnlUpdate_2 disappear and reappear after postback of some controls in that updatepanel (not the apply button, it close the modal after postback). I try all the combinations and the problem persists. So I put both updatepanels as conditional and in some way it works; now the problem is that when I click the apply button in pnlUpdate_2 to modify the gridview in pnlUpdate_1 the pnlUpdate_1 not made the postback I get the pnlUpdate_2 postback when I use some control inside the pnlUpdate_1.
How can I postback the pnlUpdate1 from pnlUpdate_2 with the apply button?
