I have a usercontrol for header in the masterpage. I need to an attribute ‘linkName’ from some of the content pages. ie for some pages it should be
<uc1:AdminHeader ID="Adminheader1" runat="server" linkClass="adminHeaderSelected" link="manageData"></uc1:AdminHeader>
and in few other pages it should be
<uc1:AdminHeader ID="AdminHeader1" runat="server" linkName="adminusers"></uc1:AdminHeader>

how can i acheive this througn content pages?

Answer 1

Add a public property LinkName to your MasterPage that get/set the UserControl’s property.
Then you can set it from the page in the following way:

((MyMaster)this.Page.Master).LinkName = "adminusers";

Where MyMaster is the actual type of your MasterPage.

VB.NET:

DirectCast(Me.Page.Master, MyMaster).LinkName = "adminusers"

Edit: If you want to add an non-existing attribute at runtime:

Create a method AddHeaderAttribute:

public void AddHeaderAttribute(string key, string Value)
{
    Adminheader1.Attributes.Add(key, Value);
}

VB.NET

Public Sub AddHeaderAttribute(key As String, Value As String)
   Adminheader1.Attributes.Add(key, Value)
End Sub

Call this method in the way described above, for example

((MyMaster)this.Page.Master).AddHeaderAttribute("LinkName", "adminusers");
