asked on Hiding columns in a gridview
I have aq gridview with Autogeneratecolumns="True"
I want to hide some columns on databound so I have this:
Sub gvOnDataItemBound(ByVal sender As Object, ByVal e As System.EventArgs)
GridView1.Columns.Item(2).
End Sub
This gives me the error: "Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index "
Why ? is it because of Autogenerate="True"?

it's zero! why??
I see the columns. This is my gridview:
<asp:GridView AllowSorting="true" OnDataBound="gvOnDataItemB
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" SelectCommandType="StoredP
</asp:SqlDataSource>

I'm not totally certain about ASP.net, but maybe the event is being called twice. Once when the control is declared/initiated, then once when the data is bound.
Use an alert or create a counter for when the event is opened, to see how many times it is opened.
Even try running your hide command in a different event like OnLoad.

Anilgr. It's a GridView part of the System.Web.UI.WebControls.
From what i'm aware it does not have the DataBindingComplete event.

in a "DataBindingComplete" event handler??
I'll try it. I have another code that I make the column style change, in code behind, using onDataBound event handler. Dont think i've seen DataBinding Complete. Let me look and post back.

oh, sorry missed that you said that's for forms...
I think the ondataBound should work. I still think it's because i have "autogenerated="true".
I'll play around and google. If i find the answer, will post.

I changed to autogenerate=false and used Bound columns. Now, onDataBound works.
