Hello,

I have this little problem.

I have datagridview and on CellClick event I have this code.

C#

dg.Rows[e.RowIndex].Selected = true;

I use this event to select row on click on any cell, but now here comes the problem when I click on the Header of column to sort the column, I cant.

I get this error.

C#

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Anyone? Thanks in advance.

I changed code to this

dg.CurrentRow.Selected = true;

now it works, but still its on CellClick event, maybe something different has to be done if it should not be on CellClick event

Hi,

Cell click event is not good, you try to use Gridview RowCommand event is to be better

u can check for Header row in CellClick event and dont process for header row. Header row has index -1. so try this:

C#

private void gv_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex != -1)
    {
        //Your code
    }
}
