Selecting only cells of one row

[Peter]

Hi, 

I have a GridView with 

grid.MultiSelect = true;
grid.SelectionMode = GridViewSelectionMode.CellSelect;

How can I achieve a behavior where the user can only multiselect cells of one row? I tried to use the gridFehlzeitenuebersicht_SelectionChanging Event without success. I think I just need a nice hint in the right direction. Thank you in Advance. 

I'm using C# and RadControls for WinForms V. 2013.3.1016.40. 

Best, 

Peter

Hello Peter,

Thank you for writing.

The SelectionChanging event seems like the right place do achieve the desired scenario. There you can access the already selected cells (via the SelectedCells collection of RadGridView) and the cell which attempts to be selected (vie the CurrentCell property of RadGridView). Here is a small sample:

void radGridView1_SelectionChanging(object sender, CancelEventArgs e)
{
    if (radGridView1.SelectedCells.Count > 0)
    {
        if (radGridView1.SelectedCells[0].RowInfo != radGridView1.CurrentRow)
        {
            e.Cancel = true;
        }
    }

}

I hope this helps.

Regards,
Stefan
