Gradient Control w/ Top + Bottom Colors?

As I've been trying to make my latest plugin, I decided to add some Gradient controls to it. But the thing is, every time I go to build it I get error saying:

'PaintDotNet.ColorGradientControl.BottomColor' is obsolete: 'Use MinColor property instead'

'PaintDotNet.ColorGradientControl.TopColor' is obsolete: 'Use MaxColor property instead'

So usually I just go and comment those lines and then I can successful build the plugin. The problem with that though, is every time I change something in the ConfigDialog, they become uncommented. And it's really annoying to have to go back, find the lines that I need, and comment them every time I change anything I the ConfigDialog.

So I guess my question is, is there a better way to stop those error messages from showing up in the first place?

Thanks in advance. :D

You shouldn't be manually editing code in InitializeComponent() if you're using the Visual Studio form designer unless you really know what you're doing. Otherwise, your changes will likely either break the designer or end up getting reverted by VS's code generation.

Sorry if this seems patronising:

1. Create a custom control, Visual C# has an item template for them.

2. Override the OnLoad method in the new class.

3. Create a new instance of the gradient control with your needed properties (some obviously added to the custom control manually), fill dock it in the control and add it to the control using this.Controls.Add(gradientControlBuilder).

Ok, so I'm farther along then before, but I'm stuck again.

Here's where I am so far:

using System;
using System.Collections.Generic;
using PaintDotNet;
using System.Text;

namespace ExtractColor
{
   private override class gradientControlBuilder
   {
       private ColorGradientControl CGC = new ColorGradientControl();

   }
}

Where should I go from here?

Note that it is a method that should be overridden, not the class. Sample code:

   using System;
   using System.Collections.Generic;
   using PaintDotNet;
   using System.Text;

   namespace ExtractColor
   {
       internal class GradientControlWrapper : UserControl 
       {
           ColorGradientControl colorGradientControl;

           protected override void OnLoad()
           {
              colorGradientControl = new ColorGradientControl();
              colorGradientControl.Dock = DockStyle.Fill;

              this.Controls.Add(colorGradientControl);
           }
       }
   }

Edit: Replaced private with internal.

Edit2: Derived from UserControl.

Ok I think I got it, but I'm still getting an error message saying:

'ExtractColor.GradientControlWrapper' does not contain a definition for 'Controls' and no extension method 'Controls' accepting a first argument of type 'ExtractColor.GradientControlWrapper' could be found (are you missing a using directive or an assembly reference?)

My code matches yours exactly so I don't know what the problem is.

Yep. I even tried recopying it.

Here's my code:

using System;
using System.Collections.Generic;
using PaintDotNet;
using System.Text;

namespace ExtractColor
{
   internal class GradientControlWrapper : UserControl
   {
       ColorGradientControl colorGradientControl;

       protected override void OnLoad()
       {
           colorGradientControl = new ColorGradientControl();
           colorGradientControl.Dock = System.Windows.Forms.DockStyle.Fill;

           this.Controls.Add(colorGradientControl);
       }
   }
}

Sorry, I was writing it from memory and forgot that OnLoad takes an EventArgs parameter. Try this:

   using System;
   using System.Collections.Generic;
   using PaintDotNet;
   using System.Text;

   namespace ExtractColor
   {
       internal class GradientControlWrapper : UserControl
       {
           ColorGradientControl colorGradientControl;

           protected override void OnLoad(EventArgs e)
           {
               colorGradientControl = new ColorGradientControl();
               colorGradientControl.Dock = System.Windows.Forms.DockStyle.Fill;

               this.Controls.Add(colorGradientControl);
           }
       }
   }

If you build the project, it should show-up in the toolbox. Alternatively, if you want to replace the current gradient controls with the wrapper, backup the project and change the type names in the InitializeComponent() method to the wrapper. If any exceptions come-up with non-referenced properties, simply add getters and setters to the wrapper for those properties which proxy those properties in the wrapper's gradient box control.
