Check/UNcheck CheckBox Control when user selected row.

[July]

this is my scenario

The user can checkBox or select Row..
This grid allow select mutiple rows.

I need:
When user selected row--> check the checkBox
When user unselected row --> uncheck the checbox.

I try with:
itemCommand --> rowClick, but when I press Shif+click for select multiple rows, does not work.
SelectIndexChange --> idem.
js onRowSelected --> I couldn't find chk for check or not...

this is my code.

hello Jayesh Goyani,
I tried but does not work .
I allow selected multiple RoWs.. if I use shif + click , does nto work.


I If click in every row, lost the last selected rows.

Hi Julieta,

What selection are you trying to implement, client or server-side? I would suggest that you achieve your goal with client-side selection. In this case you can turn the EnableAutoPostBackOnRowClick property back to false. Instead of the GridTemplate with CheckBox, use the GridClientSelectColumn. Thus the user will be able to select multiple items by checking the select column checkboxes, using the [Shift]+click approach, or drag to select. And the checkboxes and selected items will be in sync. See this demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/selecting/defaultcs.aspx

Let me know if this works for you

All the best,
