Getting GridViewCheckBoxColumn value

[DenisCL]

Hello,

I would like to access a specific checkbox value in my grid.
After some hours of searching the correct syntax and way to do it, I come to you for more information.

For example, how can I get the myGrid.row[2].cell["checkbox"] value (where the cell is checkbox) outside of any events?
Actually can cast something somewhere in the cell GridViewCellInfo to get the inner checkbox value?

Thanks

regards

Hello Denis,

You are correct, you can get the cell value like that, for example:

 bool value = false;
 if (radGridView1.Rows[0].Cells["Checkbox"].Value != null)
 {
     value = (bool)radGridView1.Rows[0].Cells["Checkbox"].Value;
 }

Hope this helps, if you have any other questions or comments, please let me know,

Hello

Thanks for this little code, but I finally fall on what i'm stuck

The value is empty. When I try to cast it, i have an exception (see picture attached)

That's why I was talking about an inner value of the checkbox in the gridviewcheckboxcolumn.

Where is the checkbox value?

regards

Hello again,

What do you mean by empty? If it's null it should not enter there and if it's not null it has to be a bool... Could you provide a small sample for this case?

Hope this helps, if you have any other questions or comments, please let me know,

Hello,

My bad I didn' t notice when the checkbox state is false, it's in fact system.DBNull.

It's ok now.

the value is true when checked
