Examples

The following example demonstrates how to call the BeginResetItemTemplate and EndResetItemTemplate methods in the LayoutStyleChanged even handler of a DataRepeater control. This example requires that you have a DataRepeater control named DataRepeater1 on a form and that it contain two TextBox controls named TextBox1 and TextBox2.

private void dataRepeater1_LayoutStyleChanged_1(object sender, EventArgs e)
{
    // Call a method to re-initialize the template.
    dataRepeater1.BeginResetItemTemplate();
    if (dataRepeater1.LayoutStyle == DataRepeaterLayoutStyles.Vertical)
    // Change the height of the template and rearrange the controls.
    {
        dataRepeater1.ItemTemplate.Height = 150;
        dataRepeater1.ItemTemplate.Controls["TextBox1"].Location = new Point(20, 40);
        dataRepeater1.ItemTemplate.Controls["TextBox2"].Location = new Point(150, 40);
    }
    else
    {
        // Change the width of the template and rearrange the controls.
        dataRepeater1.ItemTemplate.Width = 150;
        dataRepeater1.ItemTemplate.Controls["TextBox1"].Location = new Point(40, 20);
        dataRepeater1.ItemTemplate.Controls["TextBox2"].Location = new Point(40, 150);
    }
    // Apply the changes to the template.
    dataRepeater1.EndResetItemTemplate();
}

Private Sub DataRepeater1_LayoutStyleChanged(ByVal sender As Object,
 ByVal e As System.EventArgs) Handles DataRepeater1.LayoutStyleChanged
    ' Call a method to re-initialize the template.
    DataRepeater1.BeginResetItemTemplate()
    If DataRepeater1.LayoutStyle =
     PowerPacks.DataRepeaterLayoutStyles.Vertical Then
        ' Change the height of the template and rearrange the controls.
        DataRepeater1.ItemTemplate.Height = 150
        DataRepeater1.ItemTemplate.Controls(TextBox1.Name).Location =
         New Point(20, 40)
        DataRepeater1.ItemTemplate.Controls(TextBox2.Name).Location =
         New Point(150, 40)
    Else
        ' Change the width of the template and rearrange the controls.
        DataRepeater1.ItemTemplate.Width = 150
        DataRepeater1.ItemTemplate.Controls(TextBox1.Name).Location =
         New Point(40, 20)
        DataRepeater1.ItemTemplate.Controls(TextBox2.Name).Location =
         New Point(40, 150)
    End If
    ' Apply the changes to the template.
    DataRepeater1.EndResetItemTemplate()
End Sub
