Unable to Find by DataField property

[Benjamin]

I have the following code in my module identifying each column's UniqueName based on their DataField property. The FindByDataFieldSafe function strangely isn't able to identify TemplateColumns and would return Nothing.

Protected Function GetGridValues(ByVal rgdGrid As RadGrid, _
                           ByVal grdEditableItem As GridEditableItem, _
                  Optional ByVal blnValidateData As Boolean = True) As String

Dim hshRowData As New Hashtable
   rgdGrid.MasterTableView.ExtractValuesFromItem(hshRowData, grdEditableItem)
   For Each strField In hshRowData.Keys
      xmleField = xmldData.CreateElement(strField)
         If Not rgdGrid.Columns.FindByDataFieldSafe(strField) Is Nothing Then
            strColUniqueName = rgdGrid.Columns.FindByDataFieldSafe(strField).UniqueName

However, if I run the following statement during debugging, using the FindUniqueNameSafe function instead, I'm able to return the value.

?cObj(rgdGrid.Columns.FindByUniqueNameSafe("colINDCUR")).DataField
"INDCUR" {String}
    String: "INDCUR"

What is wrong here?
Thanks for all the help.

Hi Benjamin,

Can you please check if you have set the DataField property of the GridTemplateColumn?

Yes, the column already has its DataField property defined in its ASPX code. As is the RadComboBox within it.

<radG:GridTemplateColumn UniqueName="colINDCUR" DataField="INDCUR" DataType="System.String" HeaderText="Currency" HeaderStyle-Width="10%">
   <ItemTemplate>
      <table>
         <asp:Label ID="lblINDCUR" runat="server" Text='<%#Bind("INDCUR")%>' Width="100%" Height="100%"/>
      </table>
   </ItemTemplate>
   <EditItemTemplate>
      <radCB:RadComboBox ID="ddlSSFXRT" runat="server" EnableLoadOnDemand="True" ExternalCallBackPage="..\..\RadGrdDDLStreamer.aspx" ItemRequestTimeout="500" Text='<%#Bind("INDCUR")%>' MaxLength="4" Skin="WindowsGray" Width="100%" DropDownWidth="300px">
         <HeaderTemplate>
            <table style="table-layout:fixed;">
               <tr>
                  <td style="width:15%; font: Tahoma; font-weight: bold; font-size: 9pt; text-align:center;">Code</td>
                  <td style="width:85%; font: Tahoma; font-weight: bold; font-size: 9pt;">Currency</td>
               </tr>
            </table>
         </HeaderTemplate>
   </radCB:RadComboBox>
</EditItemTemplate>
</radG:GridTemplateColumn>

The screen works fine actually, but I needed a new method of identifying and validating each of the column's data. It was during my R&D where I discovered this issue. So far I've made a fix around this bug, but I'm not comfortable with leaving this unsolved, for fear it could return to haunt any future development. Thanks for your time.

Hello Benjamin,

Please find the attached project to this forum post.
It seems like RadGrid1.Columns.FindAllByDataField is working as expected.

But it was FindByDataFieldSafe method where I discovered this issue. Does FindAllByDataField method operate on the same codes and does that confirm the issue doesn't happen for FindByDataFieldSafe method?

Hello Benjamin,

Please excuse me for the mistake. However, if you replace FindAllByDataField  with FindByDataFieldSafe you will see that GridTemplateColumn will be found in the example which I sent you in my previous post.
