Capturing value of DataGridView CheckBox in VB.Net

Question

I have a datagridview (unbound). Fields are Name, Family Name and Phone No and a checkbox colum.

There are ten rows in that DataGridView.

There is an OK button

I need to get message of showing which rows user has checked. The message should appear when user clicks OK button. There could be several message, checking each row one by one, in a loop.

I am not able to get this message. I tried following code in OK button

Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString

Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0

Thanks for your help.F

Answer 1

You need to do something like this:

if ctype(dgvChooseQs.Rows(0).findcontrol("whateverYourCheckBoxIsNamed"), checkbox).checked then 

'throw the message

end if

Answer 2

Do noy use the cell index. Your checkbox column must have a name so you should use it.

Otherwise, what you want to do would be something like this

For each oRow as DataGrisViewRow in dgvChooseQs.Rows

   If oRow.Cells("ColNamE").Value = True then
    'do whatever you need to do.
   End if

Next

If you feel you need to cast the column, then you can use CType, but the type is DataGrisViewCheckBoxCell, not CheckBox.
