I've got a project that I've inherited. I've been asked to remove two columns in a GridView on a website and replace them with two other columns. I've changed the html to replace the originals with the new ones however the column header names don't appear to want to change. I've run the code with the debugger on and put a break on the first line of the code c# code before it does anything and checked out the gridview object. It already has these column names assigned and I can't figure out how. I've done a search for the original column names and have been unable to find them anywhere.

Basically, my question is what controls what the column is named before the page even really loads? Every time I've searched on this I get people wanted to change it programmatically but that doesn't appear to be what my issue is from what I can tell. I've attempted to go into the properties of the object like it was suggested here but it shows the new fields not the old ones.

The following is the relevant (I believe) HTML code which is creating this gridview and object.

<asp:GridView ID="gvTopSearch" runat="server" AllowPaging="True" 
    AllowSorting="True" PageSize="15" AutoGenerateColumns="False"
    DataKeyNames="NID,CID" Width="100%" OnPageIndexChanging="gvTopSearch_PageIndexChanging"
    OnSorting="gvTopSearch_Sorting" 
    onrowdatabound="gvTopSearch_RowDataBound" 
    meta:resourcekey="gvTopSearchResource1" >
    <Columns>
         <asp:TemplateField SortExpression="NewField1" HeaderText="NewField1" 
            meta:resourcekey="TemplateFieldResource5">
            <ItemTemplate>
                <%#Eval("NewField1")%>
            </ItemTemplate>
             <HeaderStyle Width="75px" />
        </asp:TemplateField>
        <asp:TemplateField SortExpression="NewField2" HeaderText="NewField2" 
            meta:resourcekey="TemplateFieldResource6">
            <ItemTemplate>
                <%#Eval("NewField2")%>
            </ItemTemplate>
            <HeaderStyle Width="75px" />
        </asp:TemplateField>
    </Columns>
    <AlternatingRowStyle CssClass="fieldName" HorizontalAlign="Left" />
    <EmptyDataTemplate>
        <table width="100%" border="0" cellpadding="0" cellspacing="0">
            <tr>
                <td align="center" style="padding-top: 50px; padding-bottom: 50px; padding-left: 60px;">
                    <img src="" alt="" />
                    <b>
                        </b>
                </td>
            </tr>
        </table>
    </EmptyDataTemplate>
    <HeaderStyle CssClass="fieldNamewithbgcolor" HorizontalAlign="Left" />
    <PagerStyle CssClass="Paging" />
    <RowStyle CssClass="gridbgcolor" HorizontalAlign="Left" />
</asp:GridView>

"NewField1" and "NewField2" are supposed to be displayed but aren't.

  • Did u try cleaning the project and building it all again ? –  Oct 26 '12 at 13:57
  • You can check your code behind to make sure the column names aren't being set in there. Thats done sometimes with our pages. Also you're refreshing with ctrl+f5 to make sure you're not getting a cached version, right? – Steve's a D Oct 26 '12 at 13:59
  • What value does it give in header check if it gives the value of variable newfield1 and 2 ? –  Oct 26 '12 at 13:59
  • and also check the design view of your page what does it show there –  Oct 26 '12 at 14:02
  • Also, the column names could be set with a label in the code-behind (for internationalization purposes), so searching for the original column names might not show you what you're looking for – Steve's a D Oct 26 '12 at 14:03
  • 1.) I have cleaned and rebuilt the project. 2.)have ctrl+f5'd multiple times. I originally changed the code behind not in the properties. 3.) not sure what you mean by the header check. 4.) It shows the new values in the design view. 5.) I've tried to find if they're set there, however as I mentioned in the question itself, if I debug it the column names are already set as the old values before any code is run in the page_load function. – sparrow Oct 26 '12 at 14:37

Gah! I hate this stupid project. I've found where the issue is finally (it's only taken about 3 days).

In the same directory there's apparently an App_LocalResources folder with a resx file in it. In that file are key-value pairs including ones seen above 'TemplateFieldResource5' and 'TemplaceFieldResource6' and they were linked with the old column names. I've changed them to the new column names and it works.

Thanks to those who attempted to help me with your comments. If this is what you meant by the code behind Steve I misunderstood.
