Windows.Forms.Datagrid - Hyperlink Column: How to?

Hi, I am coding a Hyperlink column for the Windows.Forms.Datagrid as follows:

I have derived from System.Windows.Forms.DataGridTextBoxColumn
I have overridden the paint method
I have a LinkLabel that I can use.

Now then, not worring too much about the value of the url, how do I access the cells value and paint the LinkLabel?
I presume that I can use 'this.TextBox.Text' to get the value - is this correct?

How do I use push buttons as a link button?

The examples displayed are drawing bitmaps of buttons to the screen. Given that a LinkLabel has a specific look and behaviour, I don't want to redesign the wheel and emulate it, I just want to use it.

Any ideas?

I would like to close this question as I have solved the problem myself, and I have it all working as I wanted.

To make a custom column of any kind, create a new column type based on System.Windows.Forms.DataGridColumnStyle.
This column should maintain an array of controls of the type you want to display.
You have to add each control in the array of controls to the new column (in a loop):

In the paint method you can set properties for each control:
LinkLabel linkLabel = controlArray[rowNum];
linkLabel.Text = GetColumnValueAtRow(source, rowNum).ToString();

The controls will paint themselves - don't worry about them.

A search in Google for System.Windows.Forms.DataGridColumnStyle will bring up many articles to help.
