DataRepeaterItemEventArgs Class

Provides data for the DrawItem event.

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


Public Class DataRepeaterItemEventArgs _
    Inherits EventArgs
Dim instance As DataRepeaterItemEventArgs
public class DataRepeaterItemEventArgs : EventArgs
public ref class DataRepeaterItemEventArgs : public EventArgs
public class DataRepeaterItemEventArgs extends EventArgs


Use the DrawItem event to change the appearance of DataRepeaterItem objects as they are scrolled into view.

At run time, appearance-related properties can be set based on conditions. For example, in a scheduling application, you might change the background color of an item to warn users when an item is past due. If you set a property in a conditional statement such as If…Then, you must also use an Else clause to specify the appearance when the condition is not met.


The following example demonstrates how to use the DrawItem event handler to make changes when an item is scrolled into view. This example assumes that you have a DataRepeater control that is bound to the Products table in the Northwind database.

Private Sub DataRepeater1_DrawItem(ByVal sender As Object, ByVal e _
 As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) _
 Handles DataRepeater1.DrawItem
    ' Alternate the back color. 
    If (e.DataRepeaterItem.ItemIndex Mod 2) <> 0 Then 
        ' Apply the secondary back color.
        e.DataRepeaterItem.BackColor = Color.AliceBlue
        ' Apply the default back color.
        DataRepeater1.ItemTemplate.BackColor = Color.White
    End If 
    ' Change the color of out-of-stock items to red. 
    If e.DataRepeaterItem.Controls(UnitsInStockTextBox.Name).Text _
     < 1 Then
        e.DataRepeaterItem.Controls(UnitsInStockTextBox.Name). _
         BackColor = Color.Red
        e.DataRepeaterItem.Controls(UnitsInStockTextBox.Name). _
         BackColor = Color.White
    End If 
End Sub
private void dataRepeater1_DrawItem(object sender, 
    Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs e)
    // Alternate the back color. 
    if ((e.DataRepeaterItem.ItemIndex % 2) != 0)
    // Apply the secondary back color.
        e.DataRepeaterItem.BackColor = Color.AliceBlue;
        // Apply the default back color.
        dataRepeater1.ItemTemplate.BackColor = Color.White;
    // Change the color of out-of-stock items to red. 
    if (e.DataRepeaterItem.Controls["unitsInStockTextBox"].Text == "0")
        e.DataRepeaterItem.Controls["unitsInStockTextBox"].BackColor = Color.Red;
        e.DataRepeaterItem.Controls["unitsInStockTextBox"].BackColor = Color.White;
