Hi there,

I have a content page (mypictures.aspx).

I have a Master Page with the following code:

<%@ Register TagPrefix="ECC" TagName="LeftNav" Src="leftnav.ascx" %>

......................... 

<ECC:LeftNav ID="LeftNav1" Section="Sales" SubSection="" TertiarySection="" runat="server"/>

................................ 

I have the LeftNav - Web User Control (leftnav.ascx).

Question:

Depending on the content page i am viewing (i.e. mypictures.aspx), I want to change a graphic file in leftnav.ascx file which is embedded or called by the Master Page.

I am pretty novice in ASP.NET. How will I go about doing this?

Thanks

You should be able to make changes to public properties on that user control by doing something like this in your page (note that I'm doing this in C# and I'm assuming the name of the class of your control is LeftNav. If you're using VB or your class is named something different you'll have to change the code to reflect the differences.):

Control ctl = Master.FindControl("LeftNav1");

((LeftNav)ctl).YourProperty = "whatever you want";

So you use FindControl on the Master of the current page to get access to the left nav control. Then in the second line you cast it to the type it really is so you can access the public properties of the control and you set the "YourProperty" to whatever you want. Note that in addition to this I think you need to put a register directive for your left nav control in the .aspx page you are going to do this from so that it can locate and resolve the reference to the LeftNav type.You say you want to change a graphic file so you'll need to have a public property in the leftnav.ascx control that you can set with the proper graphic name and then your control will have to use that property when it loads the graphic.
