I have a RadGrid with an Edit Form FormTemplate. I use it in PopUp mode when editing. In the popup I want to set the value of several label controls on the form, but I can't get a reference to those label controls. Is there a simple way to get a reference to those controls in the edit form template?
example:

    
            <telerik:RadGrid...> 
        
            <EditFormSettings ColumnNumber="3" CaptionFormatString="Edit Person ({0}) Details" 
        
                CaptionDataField="id" EditFormType="Template">  
        
                <EditColumn ButtonType="ImageButton" UniqueName="EditCommandColumn1">  
        
                </EditColumn> 
        
                <FormTemplate> 
        
                    <table style="width:100%;">  
        
                        <tr> 
        
                            <td class="style1">  
        
                                id</td> 
        
                            <td> 
        
                                <telerik:RadTextBox ID="tbId" Runat="server" EmptyMessage="id"   
        
                                    Width="125px" OnTextChanged="tbId_TextChanged" AutoPostBack="true">  
        
                                </telerik:RadTextBox> 
        
                            </td> 
        
                        </tr> 
        
                        <tr> 
        
                            <td class="style1">  
        
                                name</td> 
        
                            <td> 
        
                                <asp:Label runat="server" ID="lblName"></asp:Label> 
        
                            </td> 
        
                        </tr> 
        
                    </table> 
        
                </FormTemplate> 
        
                <PopUpSettings Modal="True" ScrollBars="Auto" /> 
        
            </EditFormSettings> 
        
            </telerik:RadGrid>

So I want the method "tvId_TextChanged" to trigger a db lookup that returns data and inserts it into the lblName control.

Thanks for the help!

Hi Eddie,

You can use the naming container property to access the GridEditForm which contains the RadTextBox and thereby access the label in the EditForm. Check out the code below:
cs:

    
             protected void tbId_TextChanged(object sender, EventArgs e) 
        
                { 
        
                    //code for dblook up 
        
                    RadTextBox txtbx = (RadTextBox)sender; 
        
                    GridEditFormItem editFormItem = (GridEditFormItem)txtbx.NamingContainer; 
        
                    Label lbl = (Label)editFormItem.FindControl("lblName"); 
        
                }

Thanks
