GridView.SelectedRow Property
.NET Framework (current version)
Gets a reference to a GridViewRow object that represents the selected row in the control.
Assembly: System.Web (in System.Web.dll)
<BrowsableAttribute(False)> Public Overridable ReadOnly Property SelectedRow As GridViewRow
Property Value
Type: System.Web.UI.WebControls.GridViewRowA GridViewRow that represents the selected row in the control.
When a row is selected in a GridView control, use the SelectedRow property to retrieve the GridViewRow object that represents that row.
Note |
|---|
This is the same as retrieving the GridViewRow object at the index specified by the SelectedIndex property from the Rows collection. |
This object can then be used to access the properties of the selected row.
The following example demonstrates how to use the SelectedRow property to access the properties of the GridViewRow object that represents the selected row in the GridView control.

End Sub Sub CustomersGridView_SelectedIndexChanging(ByVal sender As Object, ByVal e As GridViewSelectEventArgs) ' Get the currently selected row. Because the SelectedIndexChanging event ' occurs before the select operation in the GridView control, the ' SelectedRow property cannot be used.

Dim row As GridViewRow = CustomersGridView.Rows(e.NewSelectedIndex) ' You can cancel the select operation by using the Cancel ' property. For this example, if the user selects a customer with ' the ID "ANATR", the select operation is canceled and an error message ' is displayed. If row.Cells(1).Text = "ANATR" Then e.Cancel = True MessageLabel.Text = "You cannot select " + row.Cells(2).Text & "."
