What I have is a datatable being constructed from Sharepoint API. We dont need to worry about the sharepoint api.The code where it fills the data is as follows
Datatable dt = new datatable();

Below is the code behind for a simple aspx page. The web form contains one GridView (GridView1) and one label (Label1). I create a Data Table, then add a row to the table. I then DataBind my GridView to the DataTable. (so far so good) When I run the page I do see the GridView and the single row of data. However the checkbox shown is not enabled, meaning the user cannot uncheck or check it. (As if was not enabled)

How to get Column Data Type in Autogenerated Grid View ?
View 1 RepliesI have a datatable that looks as follows:
Make,Ford,0
Model,Fusion,0
Year,2010,0
Make,Ford,1
Model,Focus,1
Year,2010,1
I'd like to loop through each row and replace all the values of the same type in the 3rd column with a different value.
So for example I would change all the 0 to 1234 and all the 1 to 1235. So I'd end up with:
Make,Ford,1234
Model,Fusion,1234
Year,2010,1234
Make,Ford,1235
Model,Focus,1235
Year,2010,1235
Whats the best way to do that ?
