Adding value to cell in readonly column in grid associated with dataset

[Jorge Gonzalez]

FYI,

    The first column of my grid is readonly. I needed to programmatically  add a value to a cell in this column. This is how to do it:

<data table>.Columns[<column index>].ReadOnly = false;

<data table>.Rows[<row index>][<column index>] = <value>;

<data table>.Columns[<column index>].ReadOnly = false;

column index is 0 for me.

Hi Jorge Gonzalez,

Generally DataTable object does not implement INotify Property and Collection changed events. In order to have immediate UI response when underlying data is changed, you can use DataTable.DefaultView, otherwise you have to call RadGridView.Rebind() on every data change.

P.S. GridViewColumn.IsReadOnly property prevents users to edit data. There is no limitation when you change data from the code behind (just data object have to implement INotify ... changed events).
