resetting gridView SelectedRow.BackColor

I currently have a gridView (gv_news) and a detailsView, the gridView shows a list of news items, with an alternatingRowStyle backColor of Grey and Transparent. The gridView also has a selectedRowStyle backColor of green:
<SelectedRowStyle BackColor="#CCFFCC" />
<AlternatingRowStyle BackColor="#EFEFEF" />

Now when I select an item in the grid view the item turns green, once I update the item or cancel the update in the detailsView I would like the selectedRowStyle in the gridView to be reset to the default alternatingRowStyle - as if nothing is selected any more.

I have created a function which I have bound the the detailsViews Update and Cancel buttons as show below. The error I receive, when one of these buttons is clicked is:
System.NullReferenceException: Object reference not set to an instance of an object.

I would appreciate some assistance in resolving this.


Many thanks,

B
Sub selectRemove()
    Dim gv_news As GridView = CType(Page.FindControl("gv_news"), GridView)
    gv_news.SelectedRow.BackColor = Drawing.Color.Transparent
End Sub

Hi

It is very simple. After updating the database, before rebinding to the dataset, do the following

GridView1.SelectedIndex=-1;

It will reset the background color back to normal
