Hello!
Is it possible to turn off automatic selection of the first row in a GridView. The automatic selection takes place on grid creation an when rebinding the data source.
Thanks.

Hello Zzz,

Thank you for this question. 

You cannot disable the selection, however you can disable it. To do this you have to handle the CurrentRowChanging event. Please, consider the code snippet below:

void radGridView1_CurrentRowChanging(object sender, CurrentRowChangingEventArgs e)
{
    e.Cancel = true;
}

Of course you can just reset it after the binding completes:

void radGridView1_DataBindingComplete(object sender, GridViewBindingCompleteEventArgs e)
{
    this.radGridView1.CurrentRow = null;
}

A third option will be to customize the current row style:

void radGridView1_CellFormatting(object sender, CellFormattingEventArgs e)
{
    if (e.CellElement.RowElement.IsCurrent || e.CellElement.RowElement.IsSelected)
    {
        e.CellElement.DrawFill = false;
        e.CellElement.DrawBorder = false;
    }
    else
    {
        e.CellElement.ResetValue(LightVisualElement.DrawFillProperty, ValueResetFlags.Local);
        e.CellElement.ResetValue(LightVisualElement.DrawBorderProperty, ValueResetFlags.Local);
    }
}

Should you have any further questions, do not hesitate to ask.

Hello,

If you just want to deselect the first row, on repopulating the data source, just do the following on the DataBindingComplete event:

this.radGridView1.ClearSelection();
radGridView1.CurrentRow = null;

Hope this helps, if you have any other questions please let me know,

Best Regards,
