DataGridView和复选框列？

Question

Using vb.net and DataGridView in Winforms.

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

Answer 1

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.

Answer 2

Is

DataGridViewCheckBoxCell.EditingCellValueChanged

what you want?

Answer 3

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!
