DataGridView, Checkbox Column Question

Question

So... I have a DataGridView with a checkbox column.  How do I capture its check event.  The CellValueChanged event fires, but only after a different cell is clicked.

Thanks!

 Try the following. Please note there are two checks for column type, only one is needed. Seems that .EndEdit is the key

Private Sub DataGridDemo_CellContentClick(ByVal sender As Object, _

ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) _

Handles DataGridView1.CellContentClick

Dim GridView As DataGridView = DirectCast(sender, DataGridView)

If TypeOf GridView.CurrentCell Is DataGridViewCheckBoxCell Then

Console.WriteLine("Checked value is {0}", _

GetValueOfActionField(GridView, "CheckList"))

End If

End Sub

Function GetValueOfActionField(ByVal GridView As DataGridView, _

ByVal FieldName As String) As Boolean

With GridView

If TypeOf .CurrentCell Is DataGridViewCheckBoxCell Then

.EndEdit() ' Must be here else you will not get the proper value

Return Convert.ToBoolean(.Rows(.CurrentRow.Index).Cells(FieldName).Value)

Else

Throw New Exception(FieldName & "is not a CheckBox column")

End If

End With

End Function

Answer 4

If you are using VS2008 the following extension might be worth looking at

<Runtime.CompilerServices.Extension()> _

Function CurrentRowCheckBoxValue( _

ByVal GridView As DataGridView, _

ByVal ColumnName As String) As Boolean

GridView.EndEdit() ' Must be here else you will not get the proper value

Return Convert.ToBoolean( _

GridView.Rows(GridView.CurrentRow.Index).Cells(ColumnName).Value)

End Function

So in CellContentClick event

Private Sub DataGridDemo_CellContentClick() _

Handles DataGridView1.CellContentClick

If dgv.CurrentRowCheckBoxValue("CheckList") Then

End If

End Sub
