I usually code in MVC and need to access the Model. But using code behind is different.

Please tell me how to create a variable in Page Load that can be accessed on the page? It's a reference of an object, actually.

Thanks,

If you're talking about WebForms, then you just need to declare a variable at the Page level and make it public:
public class MyPage : Page
{
       public string myString = "Hello World";

       protected void Page_Load()
       {
             ....
       }
}

Open in new window

Then access it in the ASPX page with:
<%= myString %>

Open in new window

In general the tag wrapper is <%=   %>  

In this example, intiparams is a variable that I've set in my codebehind and then passed to the rest of the control.  The highlited line is:
         
               <param name="InitParams" value="<%=InitParams %>" />

and the whole control is:



 <div  id="SilverlightContainer" style="width:100%;height:100%">
         
             <object data="data:application/x-silverlight-2," type="application/x-silverlight-2"
                    width="100%" height="80%" id="silverlightControl">
               <param name="source" value="ClientBin/myCode.xap"/>
               <param name="onError" value="onSilverlightError" />
               <param name="enableGPUAcceleration" value="true" />
               <param name="background" value="white" />
               <param name="minRuntimeVersion" value="3.0.40624.0" />
               <param name="InitParams" value="<%=InitParams %>" />               <param name="autoUpgrade" value="true" />

                    <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=3.0.40624.0"  style="text-decoration:none">
                        <img src="http://go.microsoft.com/fwlink/?LinkId=108181" alt="Get Microsoft Silverlight"
                        style="border-style:none"/>
                    </a>
            </object>

        </div>


Note this is for a silverlight control but in general it works the same.
