DataRepeater.LayoutStyleChanged Event

Occurs when the LayoutStyle property value changes.

Namespace:   Microsoft.VisualBasic.PowerPacks
Assembly:  Microsoft.VisualBasic.PowerPacks.Vs (in Microsoft.VisualBasic.PowerPacks.Vs.dll)

Syntax

public event EventHandler LayoutStyleChanged

public:
event EventHandler^ LayoutStyleChanged {
    void add(EventHandler^ value);
    void remove(EventHandler^ value);
}

member LayoutStyleChanged : IEvent<EventHandler,
    EventArgs>

Public Event LayoutStyleChanged As EventHandler

Remarks

The LayoutStyle property of a DataRepeater control determines whether DataRepeater items are displayed in a vertical or a horizontal format. When this property changes, you can use the LayoutStyleChanged event handler to rearrange the child controls in the ItemTemplate to fit the new layout.

For more information about how to handle events, see Handling and Raising Events.

Examples

The following example shows how to respond to the LayoutStyleChanged event in an event handler. 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
