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

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public int GetRowSpan(
	Control control


Type: System.Windows.Forms.Control

A child control of the TableLayoutPanel.

Return Value

Type: System.Int32
The number of rows spanned by the child control. The default is 1.

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.

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);
