<p>I would like to add a DataGridViewTextBoxCell cell to a DataGridViewCell control, but as well as being able to type in the text cell as normal it must also contain a '...' button that once clicks brings up the OpenFileDialog window to allow the user to select a file. Once selected, the text cell will be populated with the full file path.</p>

<p>What is the best way to go about this?</p>

<p>Thanks</p>

This
MSDN article explains how to add a custom control to a
```
DataGridView
```
.
You should be able to make a
```
UserControl
```
that has a textbox and button on it and embed that in the
```
DataGridView
```
.
