How to get the checked columns in DataGridView

hello guys,

I am having a DataGridView control.

The first column is a checkbox column.

The users can select the checkbox column. I need to loop through the grid
rows and get
the checked checkboxes and the rows numbers

I don't know how to check if the first column checkbox is checked???

any help will be appreciated!

Hi Annie,

you could try something like this , just susbstitute the name of your
datagridview and the name or index of the cell that contains the checkbox.

For n As Integer = 0 To Grid.Rows.Count - 1
            If CBool(YourGrid.Rows(n).Cells("Selected").Value) = True Then
                Return True
            End If
        Next

HTH,

Martin

Just re-read your post, this should be closer to what you are after. Or you
could use a list of datagridviewrows and return that instead.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
        For Each num As Integer In SelectedRows()
            Debug.Print(num.ToString)
        Next
    End Sub

Private Function SelectedRows() As List(Of Integer)
        Dim list As New List(Of Integer)
        Dim Grid As DataGridView = Me.InvoicesControl1.InvoicesDataGridView

        For n As Integer = 0 To Grid.Rows.Count - 1
            If CBool(Grid.Rows(n).Cells("Selected").Value) = True Then
                list.Add(n)
            End If
        Next
        Return list
    End Function

HTH,

Martin.
