[c# win form] datagrid column width help?

[piercy]

Hi, i have a DataGrid (dgFailed) and it gets populated with two columns (which comes from arrays and sql db values). the table that populates the datagrid(dataso urce) is called tblfailed.

tblfailed
Student | Reason
Fred      | No Contact Info
james   | Cancel Button Pressed
 

Now the reason is generally always going to be longer then the name. so i need to be able to set the width of the Reason column so fit the rest of the table, 1) so it looks neat and doesnt leave grey around the edges 2) so if it get longer then they can see the rest of the reason.

the width of the datagrid is 400.

Can Anyone help?

many thanks,
Piercy

yes, i tried this but i got a object reference not set to an instance of an object error.

            DataGridTableStyle ts = new DataGridTableStyle();
            ts.MappingName = "tblfailed";
            this.dgFailed.TableStyles.Clear();
            this.dgFailed.TableStyles.Add(ts);
 
            dgFailed.TableStyles["tblfailed"].GridColumnStyles["Reason"].Width = 350;
 

Thats what i tried. i also tried it replacing "Reason" with 1 (hopeful attempt at column index) but it said index out of range...

add a tablestyle,add a textbox or label control as you want and then set the width of that textbox or label as per youe requirement.... ....set the datasource property of the textbox(or label) with which you are binding the textbox(or label) in the mappingname property....... ...
the code will look like

 
        DataGridTableStyle dgtsMystyle = New DataGridTableStyle;
        dgtsMystyle .MappingName = "tblfailed";
        DataGridTextBoxColumn  myBox = New DataGridTextBoxColumn;
        myBox .MappingName = "databaseField";
        myBox .HeaderText = "myHeader";
        myBox .Width = 350;
        myBox .TextBox.BackColor = Color.LightBlue;
        dgtsMystyle .GridColumnStyles.Add(myBox );
