Solution Explorer

[Guest]

This is a Winform.

One of my Winform icons is different than the rest displayed in the Solution
Explorer. Most of the form icon are small icon form with two text boxes and
two labels in front of the text boxes. But the odd icon, has three squares,
green square then a blue square then a red square on top of the blue square.

Why is this icon different for this win form? I went through all the
properties, same as the other forms.

Hi Cadel,

This icon is used when the file is a Component Class or a Windows Service.
Please check what class is this class inherited from in the .cs file. A
component is inherited from System.ComponentModel.Component.

I compare the code to another form and its the same. The code for
System.ComponetModel.Component is set to Null, just like my other forms.

private System.ComponentModel.Container components = null;


Here is all the code of the form. I replaced the password for security.

Hi Cadel,

Thanks for posting your code here. I tried your code on my machine, and I
was able to reproduce it.

Based on the code you have provided, I found that another class public
class DataGridNoActiveCellColumn : DataGridTextBoxColumn is defined in the
cs file. This is why the icon changed. VS.NET regard it as a component
because not only the form class is defined. This is by design. If you put
the public class DataGridNoActiveCellColumn : DataGridTextBoxColumn class
definition to another file, the icon changes back to form icon.

HTH.
