GridView - ObjectDataSource - Dynamic Columns

[Philip]

I can use a GridView and ObjectDataSource to bind my data using "Eval"
expressions ... provided the GridView and related Column TemplateFields are
defined as inline HTML.

I prefer to programmatically create the GridView Column/ TemplateField
definitions at runtime.... because I do not know the number of applicable
columns until runtime. The addition of the GridView Column/ TemplateFields
work fine, however the "Eval" expressions do not result in data from the
ObjectDataSource populating the GridView.

I programmatically add the GridView Columns/ TemplateFields first and then I
issue the DataBind method for the GridView. The "Eval" expressions are
ignored.

Any suggestions ?

Thanks

Try to use DataBinder.Eval(). If it does not work, then you can do this
in XDataBindng(), where the X is the control (eg.TextBox) that has been
bound.

Dim gridRow as GridViewRow = Ctype(Ctype(tb.NamingContainer,
GridViewRow)
Dim drView as DataRowView = CType(gridRow.DataItem,(DataRowView))

X.Text = drView("YourFieldName")


Hope this helps...
