hi all,

I am using template columns to display data in datagrid. I am using checkbox in edit item template. At runtime when I click edit I want to disable some of the checkboxes depending upon the cell value.

How can I acheive this? Please help its urgent!!!

Use the EditCommand event. Grab the value you want to compare, then grab a reference to the checkbox and disable as needed

Thanks. but I have already tried all possible ways. Actully in edit command we can read cell values but we cannot get access to controls in EditItemTemplate. we can only get access to those control in update command.
I am using template columns Itemtemplate is Lable and EditItemTemplate is checkbox. If I access checkbox in Edit command. It gives error as

Object reference not set to instance of an object.

Hi,
I'm also facing the same kind of problem can u put ur code then i can do cross-verification.
