TableLayoutPanel.GetRowSpan(Control) Method


Returns the number of rows spanned by the specified child control.

 int GetRowSpan(System::Windows::Forms::Control ^ control);
public int GetRowSpan (System.Windows.Forms.Control control);
member this.GetRowSpan : System.Windows.Forms.Control -> int



A child control of the TableLayoutPanel.


The number of rows spanned by the child control. The default is 1.


The following code example uses the GetRowSpan and SetRowSpan 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;
            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


            xSpan = 2
            ySpan = 2

        End If

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

    End If

End Sub


Row spanning is often useful for positioning a control that is considerably taller than its peers.

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