    I need to iterate through the grid's rows and determine the boolean value for the checkbox column. This operation occurs when the user clicks on a button outside of the grid.


    My attempts thus far have not returned 'true' on any rows that have the checkbox checked.


    1.For x As Integer = 0 To dgvMain.RowCount - 1
    3.    If DirectCast((dgvMain.Rows(x).Cells("colTag")).ColumnInfo, Telerik.WinControls.UI.GridViewCheckBoxColumn).Checked = True Then
    4.        _mvTaggedItems &= dgvMain.Rows(x).Cells("colItem").Value & DataBASIC.VM
    5.    End If

    After improving my query, I found a good example. Line 06 is what I used, which works. There is probably a more efficient answer.

    01.Private Sub BuildRecord()
    03.    Try
    04.        For x As Integer = 0 To dgvMain.RowCount - 1
    05.            Dim bTagged As Boolean = False
    06.            Boolean.TryParse(dgvMain.Rows(x).Cells("colTag").Value, bTagged)
    07.            If bTagged Then
    08.                _mvTaggedItems &= dgvMain.Rows(x).Cells("colItem").Value & DataBASIC.VM
    09.            End If
    10.        Next
    11.        If Strings.Right(_mvTaggedItems, 1) = DataBASIC.VM Then
    12.            _mvTaggedItems = Strings.Left(_mvTaggedItems, _mvTaggedItems.Length - 1)
    13.        End If
    14.    Catch ex As Exception
    15.        ShowErrorBox(ex.Message)
    16.        _error = True
    17.        Exit Sub
    18.    End Try
    20.End Sub
