DataRepeater.CurrentItemIndexChanged Event

Occurs when the CurrentItemIndex changes.

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

public event EventHandler CurrentItemIndexChanged

The CurrentItemIndex changes when the user selects a new DataRepeaterItem or when the CurrentItemIndex is set in code.

Setting the CurrentItemIndex property scrolls the DataRepeaterItem that has the equivalent index into view.

For more information about how to handle events, see Consuming Events.

The following example demonstrates how to use the CurrentItem property to make changes when an item is selected. It assumes that you have a form that contains a bound DataRepeater named DataRepeater1, a bound TextBox named UnitsInStockTextBox, and a Label named LowStockWarningLabel.

Private Sub DataRepeater1_CurrentItemIndexChanged(ByVal sender _
 As Object, ByVal e As System.EventArgs) Handles _
 DataRepeater1.CurrentItemIndexChanged
    ' Exit if the control is first loading.
    If DataRepeater1.CurrentItem Is Nothing Then Exit Sub
    ' Check for zero or negative quantity.
    If _
 CDbl(DataRepeater1.CurrentItem.Controls("UnitsInStockTextBox").Text) _
 < 1 Then
        ' Display a the warning label on the form.
        Me.LowStockWarningLabel.Visible = True
    Else
        Me.LowStockWarningLabel.Visible = False
    End If
End Sub
