I've created a custom Winforms control by subclassing from the DataGridView.
The custom datagrid view defines it's own columns and mappings.
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.
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.
Custom Datagrid:
partial class StrategyGrid
{
private System.ComponentModel.IContainer components = null;
protected override void Dispose(bool disposing)
{
if (disposing && (components != null))
{
components.Dispose();
}
base.Dispose(disposing);
}

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.

It seems like you have not assigned Column's DataPropertyName in those columns. if you have created columns manually and assigning DataSrouce to the data grid the unmatched column will be generated automatically. Get more information and example about DataPropertyName on MSDN

go to gridview properties or F4 --> Uncheck Auto Generated Coloumns ="False"
