Changing layout background from red to blue through button add-in with C# and ArcObjects?

Toggling Your Layout Background from Red to Blue with a C# Button in ArcMap: A How-To

Ever wished you could tweak ArcMap’s layout a bit more easily? I know I have! That’s where custom add-ins come in, letting you bend ArcGIS Desktop to your will. One super handy trick is creating buttons that do specific things. Imagine, for instance, instantly swapping your layout’s background color with a single click. Sounds neat, right?

Today, we’re diving into building a button add-in that does just that: toggles the layout background between red and blue. Think of it as a quick way to see how your map looks with different color schemes.

ArcObjects and Add-ins: The Building Blocks

So, what’s under the hood? ArcObjects is basically the engine that powers ArcGIS. It’s a massive library of pre-built components that you can use to create custom applications and extend ArcMap’s capabilities. Add-ins are like little extensions you build using these components, adding new features to ArcMap. And the cool part? You can build them using .NET languages like C# or VB.NET.

Getting Your Development Gear Ready

Before we start coding, make sure you’ve got these installed:

• ArcGIS Desktop: This gives you ArcMap itself, along with the ArcObjects library.
• ArcObjects SDK for .NET: This is your toolbox, packed with the tools and references you need to work with ArcObjects in .NET.
• Microsoft Visual Studio: Your coding headquarters, where you’ll write and debug your C# code.

Let’s Build an Add-in Project

Alright, time to get our hands dirty!

This sets up a new project with all the right pieces in place, including a template for your button add-in.

Making the Button Do Something

Now for the fun part: making the button actually do something. The real magic happens inside the button’s OnClick method. This is the code that runs every time you click the button.

Here’s the C# code that swaps the color:
