I have a problem when the databound gridview is not getting refreshed by the trigger that set to the dropdown outside the update panel. Both controls on ascx control that resides on the tabpanel within aspx page. I realise that both need to be in the same contianer, but because it's an ascx, I can't use Content (but it's used on the aspx main page. How to trigger the refresh of the grid?Here's the simplified code:
//Main Page - aspx
<asp:Content
ID="Content1"

I need to do a partial update of a page using an UpdatePanel but I want to throw it using onkeydown. Is there a way to do this by creating a custome asyncpostback trigger.
View 4 RepliesI'm sure I'm missing something extremely obvious here, but at this point I can't see it so I need the help.Anyway, I've got a repeater inside of an UpdatePanel. As of right now, I've stripped it down to this, just to try and isolate the problem:

Whether I add the handler during itemdatabound or I add the handler within the repeater itself, it doesn't seem to matter...the event itself doesn't fire. The AutoPostback itself seems to fire, but the event itself doesn't.
In the code below, I learned to use a trigger to either display or hide a panel (pnlMaidenName_Edit) when the user clicks on either side of a radio button (rblGender_Edit). The problem now, however, is that whenever rblGender_Edit is assigned a SelectedValue of 2 for female, the hidden textbox displays in a location way out of position from where it should be. Also, the radio list button displays again, as shown in the following screenshot, near where the textbox now displays.

In my application i have placed one label in the update panel and in triggers one textbox and one dropdownlist.
<asp:UpdatePanel ID="TestPanel" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:Label ID="lblTest" runat="server"></asp:Label>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="txtTest" EventName="TextChanged" />
<asp:AsyncPostBackTrigger ControlID="ddlTest" EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
In the textbox if i gave any wrong input then i am displaying the error message with label "lblTest".The error is displayed in the label sucessfully but when i am selecting the ddlTest dropdownlist the error message is disappeared.
I have a CheckBox that is located inside a SelectItem Template. The CheckBox has Autopostback= true. Located outside the list view is a label. When the CheckBox is checked, I would like to trigger an the Updatepannel that includes the label. Instead I get an error message "'CheckBox1' could not be found for the trigger in UpdatePanel 'UpdatePanel3'. The code snippet is as follows:

I've got a page with two ContentPlaceHolders. In first there is UpdatePanel with GridView. In second I located DropDownList which is trigger for UpdatePanel.
<asp:UpdatePanel ID="stanUpdatePanel" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true" >
<ContentTemplate>
GridView & other stuff
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="ATDropDownList"
EventName="SelectedIndexChanged" />
</Triggers>
</asp:UpdatePanel>
Running the page causes error: "Control with ID 'ATDropDownList" could not be found for the trigger in UpdatePanel". I thought it was because the ATDropDownList is located inside ContentPlaceHolder. So I changed ATDropDownList's ID to UniqueID as follow:
<asp:AsyncPostBackTrigger ControlID="ctl00$ContentPlaceHolder2$ATDropDownList" (...)>
Everything works good, but I want to change it from page's code-behind. I tried to put

In the code below, I learned to use a trigger to either display or hide a panel (pnlMaidenName_Edit) when the user clicks on either the female or male designation of a radio button (rblGender_Edit). (Sorry that the code isn't displaying right here; I tried two or three times to correct it.)

I created a MultiHandleSliderExtender on a web form. All works well with updating the two textboxes with the value. The problem is that when I switch to designer mode, I get the following error:
The code is as follows:
[Code]....
[Code]....
[Code]....
The control works and the 2 text boxes get updated, but I tried putting in an update panel with a trigger on mh_1_BoundControl but it never fired. I removed it thinking that was the cause of the error, but no luck.
Now when I add another sliderextender below it for a different value, the code throws an error:
Microsoft JScript runtime error: Sys.InvalidOperationException: Type AjaxControlToolkit.SliderOrientation has already been registered. The type may be defined multiple times or the script file that defines it may have already been loaded. A possible cause is a change of settings during a partial update.
I found this example on this site and tried implementing it but to no avail.
I need to run a SELECT box [on]change handler after changing the selectedIndex.
I see the selectBox._events['change'][0].handler() method added by $addHandler, but what is the ASP.NET Ajax way to raise it as an event?
The backup plan is to set sel.onchange directly and skip ASP.NET Ajax events completely.
I followed the exact step on the tutorial, but it seems that the GetCompletionList never get triggered.

I have a problem and i have been stuck on it for a while now: I have a ListBox generated dinamically on the page at the first init of the page. That part of the page will never make a postback again while being used.
Say i have 10 UpdatePanels in the same page and there will be a maximum of 10 ListItems in my ListBox. How can i make every ListItem in the ListBox be a trigger for my existing UpdatePanels , so that when i doubleclick one ListItem , the apropiate UpdatePanel will be updated ? Or if you have any other close solutions.
