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

public int GetColumnSpan(
	Control control
)

Parameters

control
Type: System.Windows.Forms.Control

A child control of the TableLayoutPanel.

Return Value

Type: System.Int32

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

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.

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);
      }
  }
