自定义的DataGridView重复列自定义、DataGridView

我创建了一个自定义的WinForms控制从DataGridView的子类。

I've created a custom Winforms control by subclassing from the DataGridView.

自定义数据网格视图定义它自己的列和映射。

The custom datagrid view defines it's own columns and mappings.

不过，每当我将其拖出工具箱到窗体上的设计图面，形式再现了列控制（DataGridViewTextBoxColumn）在自定义控制每一列，这样，我结束了列我要双数有。

However whenever I drag it off the toolbox and onto the design surface of a form, the form recreates a column control (DataGridViewTextBoxColumn) for each column in the custom control, such that I end up with double the number of columns I should have.

总体思路是控制已经是自我意识，所以我并不需要的形式，做任何事情。很显然，我忽略了一些简单的，但我更多的Web比Windows并没有什么马上站出来的原因这一点。

The whole idea is that the control is already "self aware" so I don't need the form to do anything. Clearly I've overlooked something simple but I'm more Web than Windows and nothing immediately stands out as the cause for this.

自定义Datagrid的：

Custom Datagrid:

 partial class StrategyGrid
{
        private System.ComponentModel.IContainer components = null;


        protected override void Dispose(bool disposing)
        {

            {
                components.Dispose();
            }
            base.Dispose(disposing);

不知道在它的读取......具有这些列的这一规定，但它是错误的。他们已经$自定义的控制范围之内p $ psent。我想，也许事情做AccessModifiers，但似乎无法工作了。

Not sure where it's reading this "requirement" of having these columns from... but it's wrong. They are already present within the custom control. I thought maybe something to do AccessModifiers but can't seem to work it out.

自定义的DataGridView重复列自定义、DataGridView
