Seems you are trying to convert object of type Master into your custom type

try to return MasterPage in the function instead of perpetual_inventory.MasterPage

What you have to do is caste the master page properly. The variable you use for storing the reference of your master page must be of the same type (i.e. type of your master page class)

Assuming my master page is MyMaster in MyNamespace, so from a content page, I would use code like one shown below to access my master page:

'Code in content pane

MyNamespace.MyMaster objMasterInstance = (MyNamespace.MyMaster) Page.Master;
return objMasterInstance //Now you are returning the correct master page. You should not just return the microsoft's System.Web.UI.MasterPage class instead must return your own class variable's instance like the one I have shown.

Thank you for reviewing this soluion
 I have interpreted what you said to do is make a property in the code behind of the master page that must return the correct master page.
Please see if the code below is correct.

public Prepetual_Inventory.MasterPage menuMasterPage 
	{
 
		 
        get
        {
            Prepetual_Inventory.MasterPage objMasterInstance = (Prepetual_Inventory.MasterPage)Page.Master;
            return objMasterInstance;
        }
    }

Hello,
Looks ok to me, however I have one double, is your master page's class name really 'MasterPage ' ?   because for creating master page you inherit from
System.Web.UI.MasterPage.   I just wanted to confirm the name of your master page

Sample definition of master page code behind:
public partial class abc : MasterPage
{
...
}
So what exactly you have in place of 'abc' shown here in example. If its Prepetual_Inventory.MasterPage, its ok else reply with that line as comment and I'll look into it.
Hope it helped.

Try with this directive below your @Page:

<%@ MasterType VirtualPath="PathToYourMasterPageFile" %>
