Configure a DataGrid for limited user access

Hi,

I have a datagrid that is bound to a datatable in code and I am using DataGridTableStyles to format the grid just the way I want it to look. I don't want the user to be able to add any new rows so I set the dagatgrid.ReadOnly property to TRUE. However, there is one column of rows that I do want the user to be able to change. In this case I was thinking the user could type a new number in a particular cell and then click on a button to store the changes back to the original database table.

So, is there any way to prevent the user from adding rows to a datagrid and keep the entire datagrid as Read-)nly except for one column?

Thanks,
Charlie

I assume you are using VS 2003:

To prevent the users from adding rows, you have to set it in the datatable being used as a datasource.
An example is:  

Dim ds as new dataset
'---------------------
'Fill dataset here
'---------------------

'Now turn off the new row
ds.tables(0).DefaultView.AllowNew = False
datagrid1.datasource = ds.tables(0)

The Second part of your question is about locking down all but one column:

You can set each individual column of the datatable as readonly.

ds.tables(0).Columns(0).readonly = True
ds.tables(0).Columns(1).readonly = True
ds.tables(0).Columns(2).readonly = True
'etc....
ds.tables(0).Columns(3).readonly = false ' This one is editable.



Hope that helps
