I have:

Code: 
this.myGrid.Items[e.Item.ItemIndex].Cells[4].Text

and it works great as long as I don't add a column in before this one. If I do then this is off by one. Is there a way to do this by name. I am using a datagrid, asp.net 1.1

The items don't have ids so how would I get a hold of the correct one.
I want to get a handle on a bound column at the selected index.
 
Instead of using 4 you could use a variable.

or

Instead on text in the cell you could have a label, give it an id then use FindControl.
 
Humm. not exactly what I had in mind.
What do you mean by a variable?

I guess without an id there really is no way to reference that cell without a digit. There has to be a way.
 
Well for instance in one application I've worked on a certain user control which had a datagrid was consumed by several pages. This datagrid had the same 8 columns of data for all the pages except for 1 which only had 7 of the 8 columns. The order of the columns was always the same, but processing had in column 2 that were dependant on columns 5 and 7 in all of the pages except for one, where because of that missing column it was columns 4 and 6. So in the control we had a property called ColumnOffset which looked something like so:

Visual Basic: 
Public ReadOnly Property ColumnOffset As Integer
      'This is more psuedo code than anything
      If Me.Page.HasSpecialItem Then
            Return 0
      Else
             Return 1
      End If
End Property

Then in the OnItemDataBound event we had something similiar to:

Visual Basic: 
    e.Item.Cells(0).Text = SomeGenericFunction(e.Item.Cells(5 - Me.ColumnOffset), e.Item.Cells(7 - Me.ColumnOffset))

This SomeGenericFunction would evalute the content of the cells and return necessary text, but the point is that by using this ColumnOffset variable, regardless of number of columns shown we were able to get the information we were looking for.

Now this might be exactly what you need, but it's the kind of 'variable' type of thinking that I was eluding to.
