RadGrid Requirement with "InPlace" Edit mode

[Nani]

Hi Telerik Team,

I have a RadGrid requirement that needs "InPlace" Editmode in which there need to be two dropdown columns one depends on other dropdown selection...

so i have seen a example in your site 

http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/validation/defaultcs.aspx

in this example when "Adding new Record" can i load data in second "Dropdownlist" depending on the first "Dropdownlist" selected value.
If so what is the best template column i can use to have an access on Dropdownlists.

Can u please guide me with correct approach how to obtain this requirement.

Its urgent...Please do respond

Thanks in Advance

Hello Nani,

The project in the code library below shows how to use related RadComboBoxes for Insert and Update operations in RadGrid:
http://www.telerik.com/community/code-library/aspnet-ajax/general/using-related-radcomboboxes-in-radgrid.aspx

Give it a try and see if it works as you expected.

All the best,

HI Pavlina,
It almost worked and i have one more concern of setting the "Combobox value" to the label text when i hit "Edit button". I am attaching code and also the snipshot how its  behaving...

And more concern is when i hit "Add new record" i have a required field validators for the columns and "Source Breakdown*" combobox should reflect according to the "Source*" combobox but before firing the "Selectionchanged event its firing "validators" and "Selection change event is not firing.
*Find in snipshots attached
