gridview 突出显示当前行

是否有内置方法可以突出显示网格视图中当前选定的行？

我的 gridview 中的每一行都有一个按钮（通过 ButtonField）。当用户按下此按钮时，背景颜色会发生变化......我这样做：

Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand
    If e.CommandName = "Select" Then
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Dim selectedRow As GridViewRow = gvTransferOwner.Rows(index)
        selectedRow.Style.Add("background-color", "#ffcccc")
    End If
End Sub

这会突出显示该行，但是一旦用户按下另一行中的按钮，它仍然会在所有先前按下的行中保留该颜色。

有没有办法让一次只突出显示一行（当前选定的行）？

Thanks

如果使用全局变量来存储正在选择的行的索引，则每当选择新行时都可以将该行更改回原始颜色。

Dim previousSelected As Integer 'global variable to store the last selected index
Protected Sub gvTransferOwner_RowCommand(sender As Object, e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles gvTransferOwner.RowCommand
    If e.CommandName = "Select" Then
        Dim index As Integer = Convert.ToInt32(e.CommandArgument)
        Dim selectedRow As GridViewRow = gvTransferOwner.Rows(previousSelected)
        selectedRow.Style.Add("background-color", "#ffffff") 'change it back to original color
        selectedRow = gvTransferOwner.Rows(index)
        selectedRow.Style.Add("background-color", "#ffcccc") 'change the color of the new row
        previousSelected = index
    End If
End Sub
