ComboBox not passing selected value to content page

[Richard]

I am new to this stuff so I may be the issue.  I have a master page and content page.  On the master page I have a combobox.

<telerik:RadComboBox ID="cbBox" runat="server" AutoPostBack="True"
                         Height="120px"
                        ErrorMessage="No Items Available" Sort="Ascending">
 </telerik:RadComboBox>

 

 Fill by code behind(c#):

 

using (WorkFlowEntities items = new WorkFlowEntities())
 {
   {
     this.cbBox.DataSource = from c in items.vw_UserAuth
where c.DomainName== "me"                                                         select new { c.Name, c.Item };
 this.cbProject.DataTextField = "Name";
 this.cbProject.DataValueField = "Item";
 this.cbProject.DataBind();
 this.cbProject.Items.Insert(0, new RadComboBoxItem("Select a item", string.Empty));
 }
}

 All of this works fine.  I am trying to access the combobox from a content page but it always returns "" not null though.  I am using this code to get the values:
 

 

private string getSelectedProject()
       {
           RadComboBox masterCombo = (RadComboBox)Master.FindControl("cbBox");
           if (masterCombo != null)
           {
               return masterCombo.SelectedValue.ToString();
           }
           else
           {
               return null;
           }
       }

I know there is data being return because i tried hard coding the selected value.

Hello Richard,

Your code worked perfectly at my end when the RadComboBox placed directly on master page . I suppose the control (RadComboBox ) is nested inside any other control. If so you need to access the container control first and then access the control (using FindControl method).

Thanks,
