Selecting a coloumn in a datagrid view

TowerMan

Hi,

I have a coloumn of select buttons in my gridview and what I am tring to do is that when the user selects the button, the background colour of the gridview will be highlighted. I am sure that something like this would be easily implemented, so far what I have tired is that when the button is clicked it call a
GridViewCommandEvent args method. Below is my code

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        GridView1.SelectedRow.BackColor = System.Drawing.Color.Blue;         
    }

I would have though that, that would work but it throws a runtime error. Can anybody help??

Try it in the SelectedIndexChanged event instead, it'll work in there. I'd say your getting a NullReferenceException error. I don't think there is a selected row if you're using RowCommand, hence the null reference.
