Examples

The following code example uses the GetColumnSpan and SetColumnSpan methods to set the width of a Button control in a TableLayoutPanel.

private void toggleSpanBtn_Click(
    System.Object sender, 
    System.EventArgs e)
{
    Control c = this.TableLayoutPanel1.GetControlFromPosition(0, 0);

    if ( c != null )
    {
        int xSpan = this.TableLayoutPanel1.GetColumnSpan(c);
        int ySpan = this.TableLayoutPanel1.GetRowSpan(c);

        if (xSpan>1)
        {
            xSpan = 1;
            ySpan = 1;
        }
        else
        {
            xSpan = 2;
            ySpan = 2;
        }

        this.TableLayoutPanel1.SetColumnSpan(c, xSpan);
        this.TableLayoutPanel1.SetRowSpan(c, ySpan);
    }
}

Private Sub toggleSpanBtn_Click( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles toggleSpanBtn.Click

    Dim c As Control = Me.TableLayoutPanel1.GetControlFromPosition(0, 0)

    If c IsNot Nothing Then

        Dim xSpan As Integer = Me.TableLayoutPanel1.GetColumnSpan(c)
        Dim ySpan As Integer = Me.TableLayoutPanel1.GetRowSpan(c)

        If xSpan > 1 Then

            xSpan = 1
            ySpan = 1

        Else

            xSpan = 2
            ySpan = 2

        End If

        Me.TableLayoutPanel1.SetColumnSpan(c, xSpan)
        Me.TableLayoutPanel1.SetRowSpan(c, ySpan)

    End If

End Sub

Remarks

Column spanning is often useful for positioning a control that is considerably wider than its peers.

This method is called by the ColumnSpan property, which the panel adds to its child controls at design time.
