I have created a datagrid in C# Windows Application and i want to place a checkbox in it.I have tried this link
http://www.windowsforms.net/FAQs/default.aspx?PageID=2&ItemID=537&CategoryID=3&tabindex=3
I am able to place the checkboxes but can't make tht checkboxes working i.e.can't able to select and deselect the checkbox items.
i.e. the checkbox functionality is not enabled.
I know this in Web Application but i m here using WINDOWS APPLICATION.
How can i do this?
