I haven't used these in awhile. I was just wondering is it possible to pass values or parameters to a user control from the aspx page. Say you register a control and then use it using something like 

<uc1:SampleUserControl id="SampleUserControl1" runat="server"></uc1:SampleUserControl>

style syntax. Can you pass parameters in there?

  • I found that it was necessary to set the CodeBehind property in the .ascx file to the associated ascx.cs/ascx.vb file – andrewb Feb 03 '15 at 22:13

Yes:

<my:Control runat="server" MyPublicProperty="Value1" MyPublicProperty2="Value2"/>

Any public property can be set in the markup as indicated above. You can get more advanced than this and support child elements, etc. too. See more information.

    Another approach is add `Control.MyPublicProperty = "Value1";` inside the Page_Load on the `.cs` file. – RaphaelDDL May 06 '13 at 17:05

    @RaphaelDDL Yes, but in general it is preferred to do what you can in the markup. If you have to do something complex, then it goes in the code-behind. If you can do it in the markup easily, then do it there. Even better - switch to MVC and stop using server controls! ;) – Josh M. Apr 21 '15 at 13:19

Create public properties in the code behind of the user control and then these could be used as attributes while declaring the user control in the page. Check here
