<p>I have a datagridview  with a DataGridViewComboboxColumn column with 3 values:</p>

<p>"Small", "Medium", "Large"</p>

<p>I get back the users default which in this case is "Medium"</p>

<p>I want to show a dropdown cell in the datagridview but default the value to "Medium".  i would do this in a regular combobox by doing selected index or just stting the Text property of a combo box.</p>

Are you retrieving the user data and attempting to set values in the DataGridView manually, or have you actually bound the DataGridVew to a data source? Because if you've bound the grid to a data source, you should just need to set the DataPropertyName on the column to be the string name of the object Property:
```
```
[DataGridViewComboboxColumnName].DataPropertyName = "PropertyNameToBindTo";
```
```
Or do you mean you want it to default to Medium for a new row?
