ASP.NET Custom Server Control Help

$

0

Can anyone please help with custom server control?

I have all layout and inputs, select, buttons and images using javascript client side but I'd like to use with server side instead.

Instead of using: <input type="submit" id="cmdSubmit" name="submit" value="submit" onclick="javascript:SubmitButton" />

I would like to use this: <asp:Button id="cmdSubmit" Text="Submit" onclick="btn_SubmitClick" runat="server" />

this is my c# class.

namespace ncToolBar
{
    //-public class ncToolBar : UserControl
    [ToolboxData("<{0}:ncToolBar runat=server></{0}:ncToolBar>")]
