Public Enumeration SizeType
public enum class SizeType
| | Member name | Description |
|---|
| Absolute | The row or column should be sized to an exact number of pixels. |
| AutoSize | The row or column should be automatically sized to share space with its peers. |
| Percent | The row or column should be sized as a percentage of the parent container. |
The SizeType enumeration specifies how rows or columns of UI elements, typically controls, should be sized relative to the size of their container. This enumeration is used by the RowStyle and ColumnStyle classes to indicate their preferred sizing attributes. The TableLayoutPanel class, in turn, uses these style classes.
When laying out a container with rows or columns that have different preferred sizing attributes, any space remaining after the initial allocation will be distributed between the rows or columns whose styles have TableLayoutStyle.SizeType property values of AutoSize or Percent.
The following example shows how to set the TableLayoutStyle.SizeType property on a ColumnStyle object. This code example is part of a larger example provided for the TableLayoutPanel control.
Private Sub toggleColumnStylesBtn_Click( _
ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles toggleColumnStylesBtn.Click
Dim styles As TableLayoutColumnStyleCollection = _
Me.TableLayoutPanel1.ColumnStyles
For Each style As ColumnStyle In styles
If style.SizeType = SizeType.Absolute Then
style.SizeType = SizeType.AutoSize
ElseIf style.SizeType = SizeType.AutoSize Then
style.SizeType = SizeType.Percent
' Set the column width to be a percentage
' of the TableLayoutPanel control's width.
style.Width = 33
Else
' Set the column width to 50 pixels.
style.SizeType = SizeType.Absolute
style.Width = 50
End If
Next
End Sub
private void toggleColumnStylesBtn_Click(
System.Object sender,
System.EventArgs e)
{
TableLayoutColumnStyleCollection styles =
this.TableLayoutPanel1.ColumnStyles;
foreach( ColumnStyle style in styles )
{
if( style.SizeType == SizeType.Absolute )
{
style.SizeType = SizeType.AutoSize;
}
else if( style.SizeType == SizeType.AutoSize )
{
style.SizeType = SizeType.Percent;
// Set the column width to be a percentage
// of the TableLayoutPanel control's width.
style.Width = 33;
}
else
{
// Set the column width to 50 pixels.
style.SizeType = SizeType.Absolute;
style.Width = 50;
}
}
}
