DataGridView & Checkbox Column?

Using vb.net an开发者_如何转开发d DataGridView in Winforms.

What event should I use to know when the checkbox has changed?

Did you mean how do you know when the DataGridView changes?

A DataGridView is not a checkbox at all.

Add an event handler to handle a CellValueChanged event.

Private Sub MySubName(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged

End Sub

(replace MySubName with whatever you want, and DataGridView1 with the name of your DataGridView).

Fill in the body of the Sub to handle the event.

Is

DataGridViewCheckBoxCell.EditingCellValueChanged

what you want?

You need to set up an event handler to do work when a cell's contents have been changed. Then, based on the arguments passed, you can see if the checkbox was checked or unchecked, and do work accordingly.

    Private Sub myDataGrid_CellContentClick(ByVal sender As System.Object, _
    ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _
    Handles myDataGrid.CellContentClick
         If myDataGrid.Rows(e.RowIndex).Cells(e.ColumnIndex).Value = "True" Then
             'Checked condition'
         Else
             'Unchecked Condition'
         End If
    End Sub

Hope that helps!
