Hi,
I am using radcontrols with .net1.1 in VS2003. I want to display mastergrid and on clicking a plus sign, a child grid.I have written a simple code for this. But I cannot see the chidgrid on compiling and running the project.I cannot see even the header names of the childgrid. when I click on the '+' sign,it just refreshes the page but show even the headers.
And also I an needdatasource and detaildatabind handlers in the initialize method. But when I use breakpoint to check the flow, the events are not happening. Its just executing FillGridData and nothing else.

Can any one tel me whats happennig?
