Thanks, this pointed me in the right direction. The other reason the objects werent found was because they weren't found was because they werent actually created under the current edit mode.<br />

Hi,<br />
<br />
I'm having trouble using the findcontrol method to modify listview content on page_load. What i need to do is populate a listbox programmatically. I know the reason is because i can't modify a listview that hasnt been created yet.<br />
<br />
I get the error:<br />
Index was out of range. Must be non-negative and less than the size of the collection.<br />
Parameter name: index <br />
<br />
the index is -1, but there must be a way to access a nested control on page_load or without the user having to click something right?

accessing controls in listview on page_load

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
