I am not able to do the following

- On click of search button on search control, call method on list user control to update the results

Please help me how to do this.

Thanks agarwalrahul,

I have downloaded the code and understood.

But they are using xml to save data and another control is reading xml to bring list.

In my case I have no xml data. I need to take data from search control and produce list from the same data in list conrol.

Please suggest
