I'm trying to bind a datatable to a gridview where I've removed some of the autogenerated columns in the code behind.
I've got two template columns and it seems that when I alter the gridview in code behind and remove the non-templated columns that the templates loose the controls that are in them.
Using the following as a sample, "Header A" will continue to be visible but "Header B" will dissapear after removing any columsn that are located at index 2 and above. I'm creating columns in my codebehind for the grid as a part of a reporting tool. If I don't remove the columns then there doesn't seem to be an issue.
<asp:GridView ID="DataGrid1" runat="server" AutoGenerateColumns="false" AllowPaging="True" PageSize="10" GridLines="Horizontal">
<Columns>
<asp:TemplateField HeaderText="Header A" >
<ItemTemplate >
Text A
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
Header B
</HeaderTemplate>
<ItemTemplate>
Text B
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
For i = 2 To DataGrid1.Columns.Count - 1
DataGrid1.Columns.RemoveAt(2)
Next
EDIT
So from what I've read this seems to be a problem that occurs when the grid is altered. Does anyone know of a good workaround to re-initialize the template columns or set them up again so that when the non-template columns are removed that hte templates don't get removed as well?
