Access web control on Nested master page from content page

For example I have a DropDownList control in the inner master page. This control can be accessed from the content page in 2 ways.

1. Using the findcontrol method to access the DropDownList, you need to use the DropDownList's ClientID.

   For example :

   DropDownList list = (DropDownList)this.Master.FindControl("ctl00$ctl00$ContentPlaceHolder1$DropDownList1");

2. Expose the DropDownList control in the inner master page's code bhind, then the control can accessed directly.

• Expose the DropDownList control:

        public DropDownList list
        {
             get
             {
                    return this.DropDownList1;
             }
        }

 

• Add the masterType for the content page to strong type the master page:

  <%@ MasterType VirtualPath="~/Masterpage/NestMasterPage/MasterPage2.master" %>

   

• Access the DropDownList in the content page's codebehind:

          DropDownList list = this.Master.list;

Happy Coding…
