Hello,
I am currently evaluating RadGrid and am looking towards some Gurus for some help

I have a created a radgrid which takes data from a table and displays it in rows. One of the columns is a  GridHyperLinkColumn which is also the DataKeyName Column

ASPX Code
<MasterTableView EditMode=InPlace DataKeyNames="UniqueId">
                         <Columns>
                             <telerik:GridBoundColumn DataField="ContractNo"
                                 HeaderText="Contract Number" UniqueName="ContractNo">
                                 <FooterStyle Font-Bold="True" />
                                 <HeaderStyle Font-Bold="False" Font-Italic="False" Font-Overline="False"
                                     Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Center"
                                     Wrap="True" />
                                 <ItemStyle Font-Bold="False" Font-Italic="False" Font-Overline="False"
                                     Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Center"
                                     Wrap="True" />
                             </telerik:GridBoundColumn>
                             <telerik:GridHyperLinkColumn DataNavigateUrlFields="UniqueId,RevisionNo"
                                 DataNavigateUrlFormatString="URL"~/UpdateDetail.aspx?UniqueId={0}&RevisionNo={1}&"
                                 DataTextField="UniqueId" HeaderText="Unique ID" UniqueName="UniqueId">
                                 <HeaderStyle Font-Bold="False" Font-Italic="False" Font-Overline="False"
                                     Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Center"
                                     Wrap="True" />
                                 <ItemStyle Font-Bold="False" Font-Italic="False" Font-Overline="False"
                                     Font-Strikeout="False" Font-Underline="False" HorizontalAlign="Center"
                                     Wrap="True" />
                             </telerik:GridHyperLinkColumn>
          </Columns>
</MasterTableView>

.CS Code

protected

void gvrgPendingWorkflow_UpdateCommand(object source, GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

//Get the primary key value using the DataKeyValue.

string sUniqueID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["UniqueID"].ToString();

//Access the textbox from the edit form template and store the values in string variables.

string sContractNo = (editedItem["ContractNo"].Controls[0] as TextBox).Text;

string sRevisionNo = (editedItem["RevisionNo"].Controls[0] as TextBox).Text;

}

I am getting the following error when i am trying to read sUniqueID
"Object reference not set to an instance of an object"

However if I comment that single line I am able to read the updated values entered for sContractNo and sRevisionNo

Please advise.

Your help is much appreciated.

Regards,
Kaushik
