Hide a column in asp:GridView

[ghostwolf]

Hi, I want to hide a column in the asp:GridView, say one of the column of
asp:BoundField. But it is not allowed to put <divinside for setting it
display:none. What can I do? Thanks in millions.

To hide the third column for example ...

GridView.Columns[2].Visible = false;

MyGridView.Columns[0].Visible = false;

HOWEVER, bear in mind that this isn't actually *hiding* the column per se -
it's physically *removing* the column from the HTML being sent down to the
client, which may not be what you really want...

thanks, actually I don't really want to invisible it. It is because I want
to put a value for each row but make it hide away. Just like what we did in
windows programming for adding a value for each row. If I make the column in
asp:GridView invisible, I cannot get the value from that column.

Ah... You've discovered the additional security feature that a GridView has
but a DataGrid didn't.

Basically, Microsoft took the view that using hidden columns to store data
was a potential security risk, so they removed hidden colums from ViewState
at databind time. However, it's easy enough to work round, but be aware of
the potential security risk involved in doing this...

MyGridView.DataSource = <datasource>;
MyGridView.Columns[0].Visible = true;
MyGridView.DataBind();
MyGridView.Columns[0].Visible = false;

Correct approach, terrible implementation!

Need to set display to either none or block to make this work properly.

Thank you for pointing out the issue with the approach. It has been fixed on
the site as well as attached demo project.
