I have posted my question before. It seems that I can not find the solution.
The question:
I have datasource, say, ds which is bounded to a datagrid, dg.
Assume that ds have 5 columns, c0,c1,c2,c3,c4.
In some case, say, case 1, I want to display columns c0, c1,c2 in dg and use
c3 and c4 in code behind.
In case 2, I want to display column c0, c3, and c4, and use c1 and c2 in
code behind.
The following Possible solution do not work:
dg.Column(3).Visible = false.
My analysis from the test: dg.Column(3).Visible = false is only working for
those columns which are defined in design by DataGrid Property Builder. If
you populate a table to the datagrid via binding programmatically, it does
not work, at least in my computer.
Any good solution for it?
Thanks
David

Hi David,
The Column.Visible property works on both declaratively and dynamically
created DataGrid controls. To prove it, I put in this demo http://www.societopia.net/Samples/Da...Delegates.aspx an experiment
in hiding/displaying columns with a dynamically created DataGrid.

I have played your example. It is a very good example to help me for other
checkbox control of cell in a datagrid. I will check your code.
By the way, when you drag the datagrid from toolbox, have you unchecked any
property for it?
Thanks

Hi David,
The example whose link I provided below was not created using the VS.Net
toolbox at all. It is done using a notepad. The controls are created
dynamically (not placed declaratively on the web form). If you want another
sample that is done declaratively (i.e. you can recreate using the VS.Net)
review this one http://www.societopia.net/Samples/Da...olsEvents.aspx
