I have a Radgrid containing a dropdown list in template column. On the selected index changed event of the dropdown, I want to bind the detail rows based on the value selected in master row.

Example: if the user selects 1 from the dropdown of master row, I need to have 1 detail row, if user selects 2, I need 2 detail rows.

Please help.

Thanks,

-Venu.

Hello Venu,

You can achieve this requirement using NestedViewTemplate:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/hierarchy-with-templates/defaultcs.aspx

Using the SelectedIndexChanged event handler of the combo, you can access the NestedViewItem of the corresponding GridDataItem and find the inner grids using FindControl(). Then, you can set their Visible properties accordingly to display 1, 2 or more detail grids at the same time.
