readonly cells

[Robbie]

Hi There,
I want to mark cells as readonly based on a given value in the databounditem and in some situations i want to mark the complete row as being readonly.

Is this possible?

many tanx in advance, grtz

Hi Robbie,

Currently, we have ReadOnly property for the RadGridView control, but not for separate rows or cells. However, you can achieve the desired behavior by canceling the CellBeginEdit event on a specific condition:

private void radGridView1_CellBeginEdit(object sender, GridViewCellCancelEventArgs e)
{
    // read-only just for the cell
    if(this.radGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString() == "Sales Manager")
    {
        e.Cancel = true;
    }

    // read-only for the whole row which has a specific value in a specific cell
    if (this.radGridView1.Rows[e.RowIndex].Cells[3].Value.ToString() == "Sales Representative")
    {
        e.Cancel = true;
    }

    // read-only depending on the column and row indexes
    if ((e.ColumnIndex == 3) && (e.RowIndex == 2))
    {
        e.Cancel = true;
    }

    if (e.RowIndex == 0)
    {
        e.Cancel = true;
    }
}

Tanx Nikolay !
I think this will work nicely and if you can tell me how to prevent the pencil from appearing when clicking on a cell that has a canceled beginedit event you will really make my day!!

Looking forward to your reply,
Robbie
