I have a small a problem with my navigation control. My navigation control has many menuitems. But here is just an extract to explain my problem.
<asp:MenuItem Text="Customer">
<asp:MenuItem NavigateUrl="~/CustomerLogin.aspx" Text="Log In"></asp:MenuItem>
<asp:MenuItem NavigateUrl="~/CustomerProduct.aspx" Text="Product"></asp:MenuItem>
<asp:MenuItem NavigateUrl="~/CustomerInformation.aspx" Text="Information"></asp:MenuItem>
</asp:MenuItem>
so when i put my mouse on Customer, the child menuitem drops vertically. The problem is I have a panel on the page which I use Gray Color as it background color and child menuitems are hidden behind that panel. Is there a way to show the menuitems on top of the panel beside moving the panel further down?
I put a panel control on my web form, but i'ts not showing up in the code behind when I do a me.Panel. It was for a while but I was trying to do something like me.panel.visible and it kept telling me when I ran the app that panel was not part of my form.

The Ajax control toolkit tab panel automatically inserts a space by all four corners of the body. For example, go to http://www.asp.net/ajax/ajaxcontroltoolkit/Samples/Tabs/Tabs.aspx and look at the TabPanel on the page. The is a space before "Signature:" and "Bio:" labels. How can I set the space-width to 0px; in the tabPanel body?

In a panel (panelOrder, visible=false), there are three text box, txtA, txtB and txtC. Once click a button, code fires:
panelOrder.visible = true
txtA.focus
But, focus never work. I change to Javascript, still no luck. What is wrong?
On my page i have a set of control containing parts of a form, like textboxes, checkboxes etc. I use those parts to build controls that I use in pages. For example:
UserAddToList.ascx
<asp:Panel ID="Panel1" runat="server" >
<sikt:PartFormTextboxLine runat="server" ID="samAccountName" />
<sikt:PartFormTextBoxLine runat="server" ID="name" />
<sikt:PartFormButtonLine runat="server" ID="addButton" UseSubmitBehavior="true" />
</asp:Panel>
PartFormButtonLine ascx:
<div>
<asp:Button ID="Button" runat="server" onclick="Button_Click" />
</div>
What I then want to do is to set the behavior of Panel1 to have a default button in the addbutton control. I have tried setting the Panel 1 default button to the botton in formbutonline like this: Panel1.DefaultButton = addButton.Button.UniqueID; in Page_load, but that does not work because .net throws this error: The DefaultButton of 'Panel1' must be the ID of a control of type IButtonControl. Now the button is public, so that should be ok. I have also tried ID and ClientID, with te same results. I have also tried to implement the IbuttonControl in PartFormButtonLine and map the implemented functions to the button
functions, which, as expected did not work. (Panel1.DefaultButton = addButton.ID) The problem as far as I can tell is that I cant seem to set the
"onkeypress="javascript:return WebForm_FireDefaultButton(event, 'MainContent_UserAddToList_addButton')"
of the container div to the correct value, onkeypress="javascript:return WebForm_FireDefaultButton(event, 'MainContent_UserAddToList_addButton_Button')" Everything else works, this is the last thing that needs to be fixed.. Idealy i want to fix this in the PartFormButtonLine file, as that would be better for reuse {update: removed quite abit of clutter in the ascx snippets}
I have a multi view which contains a view which contains a panel. the name of this panel is "Panel1"I have the following code and my HTML does not display in the rendered page. Any idea why this isn't working, i must be doing something wrong? sw = simple html statement, any would produce same result.
String mstring = sw.ToString();
Panel1.Controls.Add(new LiteralControl(mstring));
i am using dotnetnuke also, not sure if that is where the issue is.
At run-time I add a dropdownlist but when user selects an item there is no event for:
