Couldn't Find Updatepanel Inside Hidden Div
Feb 15, 2011
I have an Updatepanel inside hidden Div, but I am getting "Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder_ctl04_UpdatePanel1'. I am trying to show and hide this panel from code behind. Here is my code.
<div id="div1" runat="server" style="display:none">
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<table id="Table1">
<tr>
<td>
<telerik:RadComboBox ID="RadComboBox1" runat="server"
AutoPostBack="true" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
</telerik:RadComboBox>
</td>
<td valign="top">
<asp:Button ID="button1" runat="server" OnClick="button1_Click" Text="Test1"
/><br />
<asp:Button ID="button2" runat="server" OnClick="button2_Click" Text="Test2"
/>
</td>
</tr>
</table>
</ContentTemplate>
</asp:UpdatePanel>
</div>

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
[Code]....
somewhere in code, but without luck so far.

The javascript generated by the asp.net SciptManager control seems to have a bug and cant handle hidden UpdatePanels. A javascript error is thrown when a control within one updated panel tries to make another update panel visible. Is this a bug with ASP.Net ajax? And does anyone have any ideas how to get around this? heres is an example of what im trying to do
<script type="text/C#" runat="server">
protected void LinkButton1_Click(object sender, EventArgs e)
{
Panel1.Visible = true;
}
</script>
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" OnClick="LinkButton1_Click" Text="Show Panel"></asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
<asp:Panel ID="Panel1" runat="server" Visible="false">
<asp:UpdatePanel ID="UpdatePanel2" runat="server">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
</asp:Panel>
this is the javascript error that gets thrown when clicking on the "LinkButton1" link. This error comes from the javascript that is generated by the asp.net ScriptManager control
Error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ContentPlaceHolder1_UpdatePanel2'

I've got a old working project. But i like to work in 2008 with it.
So i've made a new clean project.
And imported the code, also the .cs files with the classes, the thing, i could not add a ASP.Net Folder for the App_Code (strange?).
So i made it by hand, maybe thats the problem... ?
But if i try to run the project coud'nt find the classes, while they are there, in the App_Code folder.

Code:

public bool DeleteProduct(int ID)
{
Guid UserId = Guid.NewGuid();
int rowsAffected = Adapter.Delete(ID,UserId);
// Return true if precisely one row was deleted, otherwise false
return rowsAffected == 1;
}
The problem is when I use Guid UserId = Guid.NewGuid ();.
In Table I UserId type: unique Therefore it does not work. If I use the UserId type: int working.
Error:

I'm trying to display images in a GridView (yes, still this...). [edit] Before I can come to that I have to upload some images to the database.
I've followed this tutorial for the "upload image to database" code (this worked fine for uploading images, but I don't know if the images were converted to byte):
[URL]
and I've followed this tutorial for the "display images in gridview" code (and "retrieve file" from the tutorial below).

It doesn't quite work, the GridView shows but without images
Now I'm trying to change the "save file" code according to this tutorial:

but I don't understand everything in it. When I try to upload an image I get an error on this line:

I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

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:

On an aspx page i am having a dropdownlist and a panel control the dropdownlist autopostback is true. in dropdownlist control there are two options and depending on the option selected by the user i display a user control containing ajax updatepanel with a timer configured to launch async request after every one second. the problem arises when user selects the other option in dropdownlist control and the user control gets changed in the panel control. The error which is occured is shown below:
Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_cphMainMasterPage_ChildContent_ctrlPinStatusMonitor_updpnlPinStatus'. If it is being updated dynamically then it must be inside another UpdatePanel.
I thnk the problem is that the last control which have launched the async request is no more available in the panel control and gets replaced by the new other user control.

I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
like ddl.items.insert(0,'xyz');
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.

I'm trying to add and edit an image which is located in a detailsview which is inside an UpdatePanel. After I read relevant topics in the forum I installed the Ajax Control Toolkit. Below is my source code. When I used it only for insert new image it worked great. The problem caused when I tried to implement it on the Edit mode, i.e. when I tried to edit the image and upload a different image. Unfortunately it didn't work as I hoped. Nothing happend and the image hasn't been changed. I also tried to change the IDs (AsyncFileUpload ID) to be the same in both places but it didn't work either.
The source code:
<asp:DetailsView ID="dvMovie" runat="server" Height="50px" Width="695px"
AutoGenerateRows="False" DataSourceID="sdsMovieById"
BorderColor="#E7E7FF" BorderStyle="None" BorderWidth="1px" [code].....

I've got a textbox being used to enter a password inside a wizard control. I'm trying to get a password strength meter working with it.
Unfortunately, the password box isn't visible until step 4 and this means that I can't register the event handler onload() and putting some JS next to the PW box to register the event handler doesn't seem to fire. I'm guessing this is due to the contents of the wizard being loaded through an AJAX postback.

In order to use hidden input, does the hidden input must be inside a form?
Is there any strategy to perpetuate the hidden input value between requests? So far I guess it's through query string / URL?

I have a ajax combobox inside a table row which is hidden (display:none) on page load in javascript.
When user clicks a hyperlink, i need to show this row. But when i make this row visible (display:block), the ajax combobox dropdown button and list does not show up.
If I make the row always visible, then the combobox appears fine.
I read about this problem of showing a ajax combobox which was hidden on page load, but not able to get a proper solution.
