Gridview HeaderText not changing

Hello,

I have issue can't explain with a BulkEditGridView headers.

In design view I don't know what the headers will be...it changes depending on unit set in web.config.
So I leave the header as e.g.

<asp:TemplateField HeaderStyle-Font-Bold="false" HeaderText="ABC Input [UNIT]">

and populate on Page_Load correct headers on page_load like this
Me.Production.Columns(1).HeaderText = "ABC Input [metric unit]"

The headers aren't changing though on screen.

As a test I did in Page_Load before/after setting HeaderText:

System.Diagnostics.Debug.Print("Page_Load pre-setColumnTitles  HEADER: " & Me.Production.Columns(1).HeaderText())
Me.Production.Columns(1).HeaderText = "ABC Input [metric unit]"
System.Diagnostics.Debug.Print("Page_Load post-setColumnTitles HEADER: " & Me.Production.Columns(1).HeaderText())

the first debug line gives header as "ABC Input [UNIT]" - expected, this is what it is in design view
the next debug line gives header as "ABC Input [metric unit]" - expected, it has just been changed

HOWEVER, on the screen in browser the header says ABC Input [UNIT]  - it isn't changed.

Why would this be? This is the last bit of code on Page_Load

The BulkEditGridview is in a Menu_View. Interestingly if I go from the current view to another view and back again I find that the titles HAVE been changed

Thanks in advance for help on solving this

ok I thinkn almost here with this, on page display first time the columns are same as DESIGN view,
however on clicking "Add" to add a new row the column title changes. Not sure why it doesn't get set on first load though even though I use same code!
Protected Sub Production_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles Production.RowDataBound
            If (e.Row.RowType = DataControlRowType.Header) Then
                Me.Production_GasProdGrid.Columns(COLUMN_GasExport).HeaderText = "I hope this sets column!"
            End If
    End Sub

Open in new window

yes I do bind - the data is shown.

I ended up setting a label on page_load to what I want column headers to be & window.onload javascript to do search/replace. something strange in my case means its not working. I'll accept your answer as this would be way to do it in normal scenario - there must be something wrong with my page
