</Grid>

</UserControl>

The Itemsource of it is a DataView with SQL-data.

I have now applied a RowStyleSelector and with this occured a problem: The first row is always not really selected, but highlighted. I added a picture of it.

If I click the row gets really selected and the Style gets applied. I don't seem to have this problem with Bindings to Observable Collections. But completely convert the Dataview to another Collection seems to be really time consuming.

If I set IsSynchronizedWithCurrentItem to false, it works, but I not really want to miss the Indicator.

This: grid.Loaded += new RoutedEventHandler((sender, e) => { (sender as RadGridView).CurrentItem = null; }); changes nothing.

Setting the SelectedItem to the first DataRowView initially also not works.

Has anyone any other ideas?

Benedikt

Hello Benedikt,

This is the default behavior when using a collection view. To resolve it you can set the IsSynchronizedWithCurrentItem property of RadGridView to False, as you already found out. This solution is described in the First Row is Always Selected troubleshooting article.

If you want to preserve the synchronization with the current item, you can set the property initially to False, and on the first selection that happens in the gridview to set it back to True. For example:

<telerik:RadGridView IsSynchronizedWithCurrentItem="False" SelectionChanging="RadGridView_SelectionChanging"/>

private void RadGridView_SelectionChanging(object sender, SelectionChangingEventArgs e)
{
	var gridView = (RadGridView)sender;
	gridView.IsSynchronizedWithCurrentItem = true;
	gridView.SelectionChanging -= RadGridView_SelectionChanging;
}

Can you please try this and let me know if it helps?

As a side note, the first item is gray initially because this is the visual state of the selected row when the gridview control is not focused. Once, you focus the gridview, the row enters the selected-focused visual state and its background changes to a more colorful nuance.
