Hello everyone,

I need your help, i have 2 RadGrid which each depend on other grid.
Each grid can sort. But if i sort the first grid i lost the first row selected item and the second grid give me error of grid1 cant be null

So, i would like to know how i can set the focus on the last selected item or just focus on the first row?
I use VB.NET

I have tried sample i found here, and nothing change like 

RadGrid1.MasterTableView.Items(0).Selected = True

for now in my Page_Load to get the focus i use radgrod1.items(0).focus()
but it doesn't work on the SortCommand sub, i get a javascript error message

In this sub, i get a new DataSource and i rebind the radgrid.
I have tried RadGrid1.SelectedIndexes.Add(0) with my .focus and same JS error.

Thanks for your help.

• RadGrid: In the FormTemplate I have multiple components:
• RadTextBox: Allows to search a tree in search-as-you-type manner (via AJAX), continuously updating a 
• RadTreeView: As soon as I click there I want to put the selected item (via AJAX) into a 
• asp:Label (inside an asp:UpdatePanel) and return it to the RadGrid
• There are other RadTextBox and RadTreeView elements in the form as well, allowing search-as-you type on different trees as well.
