How can we do that at server side?

Hello,

In your application are you handling the WebDataGrid RowSelectionChanged client-side event? In this event you can get the Selected row of the grid, get the grid cell you want and take the text and put it in the dropdown provider current value. For example:

function rowSelChange(sender, args) {

var dd = $find('<%= WebDropDown1.ClientID %>');

var row = args.getSelectedRows().getItem(0).get_cell(1).get_text();

dd.set_currentValue(row, true);

dd._elements["Input"].focus();

dd.closeDropDown();

}

Please let me know if you need any additional assistance regarding this matter.

*Sample is attached. Please note that the ig_res folder has been omitted due to file size constraints. For proper styling of the grid you will want to add the ig_res folder. To do so, simple open the web form designer (aspx) and accept the styles when prompted.
