DataRepeaterItemValueEventArgs Class

Provides data for the ItemValueNeeded and ItemValuePushed events.

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

public class DataRepeaterItemValueEventArgs : EventArgs

In virtual mode, use the ItemValueNeeded event to populate the child controls of the ItemTemplate with values from your data store when a DataRepeaterItem is displayed or when a new item is added.

Use the ItemValuePushed event to save changes to the child control values to your data store.

When the VirtualMode property is set to False, these events are not raised.

The following example demonstrates how to handle the ItemValueNeeded event. It assumes that you have a DataRepeater control named DataRepeater1 that has its VirtualMode property set to True. The code will resemble the following example, which is for a data source named Employees.

private void dataRepeater1_ItemValueNeeded(object sender, Microsoft.VisualBasic.PowerPacks.DataRepeaterItemValueEventArgs e)
    if (e.ItemIndex < Employees.Count)
        switch (e.Control.Name)
            case "txtFirstName":
                e.Value = Employees[e.ItemIndex + 1].firstName;
            case "txtLastName":
                e.Value = Employees[e.ItemIndex + 1].lastName;
