I've the Javascript code to do a confirmation before deletion of some records
function confirmDelete()
{
if(confirm('Delete all?'))
{
return true;
}
else
{
return false;
}
}
I've the button code here
<asp:Button ID="btnDelete" runat="server" onClientClick="return confirmDelete();" onClick="btnDelete_click" />
If i've the button outside an update panel (basically i'm using RadAjaxPanel by Telerik) it is working fine. But when the button is inside an ajax panel, even if i click OK for deleting the records the server side code is not called.

I have a VS 2003 Web app that I'm creating. I'm using a Panel control and I'm trying to apply a CSS class to this panel. However, when I try coding the following statement
<asp:Panel class="pnl2" runat="server">
it doesn't like the "class" attribute saying "could not find any attribute 'class' of element panel"? I'm used to using VS 2005 and higher and haven't seen this before. What am I doing wrong?

But I can't find a way to get the Model SelectedValue and SelectedItem when Select is clicked. After it's selected it has to be filled in the Autofield on the background, and when close is pressed the original value has to be reloaded.

We have an asp.panel that by default is set to visible=false. When a checkbox is clicked the panel is set to visible=true. The checkbox is set to autopostback and viewstate=true as well as the panel's viewstate =true. This code has worked perfectly for several years and suddenly it has started throwing an error on the built in .net java function below. It doesn't do it in the IDE when you run it either. The bold line is where the exception is being thrown.
function
ValidatorCommonOnSubmit() {
var result = !Page_BlockSubmit;
Page_BlockSubmit = false;
event.returnValue = result;
return result;
}

The CMS I use struggles with UpdatePanels in some of my custom controls and master pages during edits. I'd like to convert them dynamically to regular panels on Page_Load or Page_Init or something based on whether the page is being edited.
I'd like to convert all the UpdatePanels on a page to Panels dynamically. Finding the UpdatePanels isn't an issue, all my pages inherit from a common base class, and all my controls inherit from a common base class -- so I can override the Page_Init or whatever.
I suspect I can't covert the UpdatePanel to a regular Panel. I thought about maybe finding the UpdatePanel, adding a Panel to the UpdatePanel's parent, then looping through each of the UpdatePanel's controls and adding them to the new Panel, then removing the UpdatePanel.
But if I add a new Panel, it'll be at the end, can you add a Panel in the middle... maybe with Insert? This shouldn't be difficult, but am I making it too difficult? Is there a simpler way? Anybody ever done stuff like this?
Update I ended up override the OnInit function on my MasterPage base class to readd the UpdatePanel to the ScriptManager after it moved per Philippe's comment on [URL]
protected override void OnInit(EventArgs e)
{
if (Page is CMSPage && Page.IsDesignMode())
{
foreach (UpdatePanel up in this.FindControls<UpdatePanel>())

I have a dynamic table that creates a div (new panel) for every TD and i want to give this div a class...
Can i add with Attributes.Add or with cssClass a class to the panel?
I am asking becouse i tried with both and got the same resault.... browser crash!!!
Every other attribute works great, and i just don't understand why....
Panel div = new Panel();
div.ID = "div" + "_" + i.ToString() + "_" + j.ToString();
div.Height = _CellHeight;
div.Width = _CellWidth;
