[RESOLVED] Get Checkbox value from DataGridView - VB.net

Trying to capture the value of a checkbox from a DataGridView. I've tried this a couple of ways but I get System.InvalidCastException. I'm not sure how else to cast this:

Code:

---


        For i As Integer = 0 To TheGrid.Rows.Count - 1
            If CBool(TheGrid.Rows(i).Cells("CheckOut").Value) = True Then
            'do stuff
            End If
        Next

        For i As Integer = 0 To TheGrid.Rows.Count - 1
            Dim ChkState As Boolean = TheGrid.Rows(i).Cells("CheckOut").Value
            If ChkState = True Then
            'do stuff
            End If
        Next

Is there a specific way to cast as a DataGridViewCheckBoxCell?

try this:

Code:

---

For i As Integer = 0 To TheGrid.Rows.Count - 1
    If CBool(DirectCast(TheGrid.Rows(i).Cells("CheckOut"), DataGridViewCheckBoxCell).Value) = True Then
        'do stuff
    End If
Next

Perfect!

Thank you, I have not used DirectCast before. I guess it acts like a forced cast? I'll read up on it. Thanks again!

You'd use DirectCast when you know the underlying type of an Object. If you're not sure of the type you could use TryCast...
