Cant access controls in edit form

[Philip]

Trying to find controls within edit form fails every time

<telerik:RadAjaxPanel ID="rpNotes" runat="server" LoadingPanelID="RadAjaxLoadingPanel1" >

                               <telerik:RadGrid ID="rgNotes" runat="server" GroupPanelPosition="Top" OnItemCommand="rgNotes_ItemCommand"  >

                                               <telerik:RadTextBox ID="txtNotesId" Visible="false" Width="200px" runat="server"></telerik:RadTextBox>

                                               Subject
                                               <p>
                                                   <telerik:RadTextBox ID="txtSubjectNotes" Width="200px" runat="server"></telerik:RadTextBox>
                                               </p>
                                               <p>
                                                   Notes<br />
                                                   <telerik:RadTextBox ID="txtMultiNotes" TextMode="MultiLine" Rows="10" Columns="10" Width="200px" runat="server"></telerik:RadTextBox>
                                               </p>

                                               <telerik:RadButton ID="rdSaveNotes" OnClick="rdSaveNotes_Click" Skin="Bootstrap" BackColor="#512479" ForeColor="White" runat="server" Text="Save Notes"></telerik:RadButton>

                                       </EditFormSettings>
                                   </MasterTableView>
                                   <ClientSettings>
                                       <ClientEvents OnPopUpShowing="PopUpShowing" />
                                       <Selecting AllowRowSelect="true" />
                                   </ClientSettings>
                               </telerik:RadGrid>
                           </telerik:RadAjaxPanel>

I am using this function here which i found on stackoverflow

 

/// <summary>
   /// Recursively searches for a server control with the given ID.
   /// </summary>
   /// <param name="id">ID of control to find</param>
   /// <returns>The matching control or null if no match was found</returns>
   public static Control FindControlRecursive(this Control control, string id)
   {
       if (control == null) return null;
       //try to find the control at the current level
       Control ctrl = control.FindControl(id);

       if (ctrl == null)
       {
           //search the children
           foreach (Control child in control.Controls)
           {
               ctrl = FindControlRecursive(child, id);

               if (ctrl != null) break;
           }
       }
       return ctrl;
   }

And this is how i use it

// TextBox txtSubjectNotes = (TextBox)item.FindControl("txtSubjectNotes");
// TextBox txtMultiNotes = (TextBox)item.FindControl("txtMultiNotes");
//add custom logic here
RadTextBox ctrl = (RadTextBox)this.FindControlRecursive("txtSubjectNotes");
RadTextBox myControl;
if (ctrl is RadTextBox)
{
    myControl = (RadTextBox)this.FindControlRecursive("txtSubjectNotes");


    //  _note.note = txtMultiNotes.Text;


    _note.subject = myControl.Text;
}

But I am getting object not found.

Hello Philip,

In this case there is no need to recursively traverse the control in order to access them. The FindControl method should be enough by itself. Please try accessing them during the ItemDataBound event handler using the approach demonstrated in the following section:
http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/rows/accessing-cells-and-rows#accessing-controls-in-editinsert-mode

I hope this will prove helpful.
