Control with image loaded from file, cant view in designer

I have a control that loads an image in the OnLoad and displays this image in OnPaint. However, when I try to use the control on a form, I can't view the form because of the following error:

Parameter is not valid.

at System.Drawing.Bitmap..ctor(String filename)
at Card_Creator.Item_Preview.Item_Preview_Load(Object sender, EventArgs e) in C:\Users\Jeremy\Desktop\SVN\Source Code\Card Creator\Card Creator\Item Preview.cs:line 72


I have seen this issue a few times in the office with trying to reference config files that are loaded in. Is there a way to work around this so I can load something in and not have the designer barf on it?


[Edit: Spelling]

Check the (inherited) DesignMode property. If this is True, don't load the image.
This property won't work in the constructor, check it in OnLoad.

Thank you. this is perfect for solving the issue.

hmm, so the solution is not working if the control with the check is double embedded. (used on a parent control, in which that parent control is used on another control)

Code:

---

if(!DesignMode)
{
          bmpCardBackground = new Bitmap("tressure_bg.png");
}

Being more specific would be helpful.

I am getting the same error I was getting before on the top most parent now.


Control 1 (with loaded image) is put onto control 2.

Control 2 is put onto Form. Form cannot load and is giving the error shown in first post. Builds fine, just can't view it in the designer.

Try using a full path (C:\Folder1\Folder2\Image.png) instead of a relative that you use now.
Also you spell "treasure" as "tressure", typo or error?
You could also try another image, like a jpg. Perhaps your png is saved in a weird format that the bitmap class can't handle?
That's all I can think of now.
