asp.net datagrid control: Hi

I have a hidden (visible=false) column on a gridview bound to a sql server
table. I am trying to access the field as;

For Each row As GridViewRow In grdEvents.Rows
If row.RowType = DataControlRowType.DataRow Then
bf = CType(row.Cells(row.Cells.Count - 1).FindControl("event id"),
BoundField)
End if
Next

but I get the 'System.Web.UI.Control' cannot be converted to
System.Web.UI.WebControls.BoundField' error. When I try to access it using
row.Cells(12).Text then it returns a blank value.

How can I access the relevant gridview column?

Thanks

Regards

Hmm - not precisely certain what you're trying to do here... Clearly, you
don't actually need to convert a column into a BoundField or anything else
just to interrogate its contents...

Sounds like you've discovered one of the new features of GridViews, whereby
hidden columns are not saved in ViewState by default...

Set the column Visible = True immediately before calling the GridView's
DataBind method, then set it Visible = False immediately afterwards...

Hi

I have used the 'Configure Data Source' to bind the gridview. Where would I
find the databind method in this case?

Thanks

Hello John,

I am guessing you used an ObjectDataSource control to act as a
datasource for the gridview? Check the following:

The DataSourceID property of the gridview is set to that of the
objectdatasource.
WHen you call DataBind() on the gridview, the SelectMethod of the
objectdatasource is implicitly called.
