C# - Add A Class To Panel Control In Code Behind?

Aug 20, 2010

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;

[Code]....

Web Forms :: Create User Control Class That Extend Panel?

Aug 31, 2010

I'm trying to create a user control class that extends Panel. Essentially, what I want to do is to have a panel that fires off an event whenever it's clicked upon.

So, I create something like this:

[Code]....

And then, in the ClickPanel.ascx.cs file:

[Code]....

I'm not exactly sure whether this would work as I haven't had the opportunity to test it yet.

The problem is that I can't have a class inherit from Panel. Creating a user control class requires that my class extend User Control - at least that's what the error messages have been saying up until now. The problem is that if I do extend it from the base class of UserControl then I lose all the functionality of the Panel itself and the entire thing is rendered pointless.

C# - Convert UpdatePanel To Panel In Code Behind?

Oct 25, 2010

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>())
