What I want to happen is that the text is blank and nothing is selected.What do I need to do to not pick up the previous values?

I'm trying to figure out how to set the index of a combobox column in a datagrid view when I load it from SQL Server. The combobox has a string in the text field and an index in the value field, and I want to set the selected index to match the value to an ID in the row from SQL. Not really sure how to bind it that way.

I'm trying to rig up a ComboBox with a Datagrid dropdown in WPF. I need the the code to be done programmatically and contained in the codebehind. Here's what I've got so far:
[Code]....
This code produces a ComboBox that contains a DataGrid with two columns and seems to look fine. Although when you click on the ComboBox and select one of the rows in the DataGrid the selection in the ComboBox doesn't work properly. (It just shows the colum headers.) I want the value in the first column of the selected row to appear as the ComboBox selection.

I have a table in database which I need to add a new column to. Normally I would load the access database and create the column but in this instance I have to many databases to amend. Is there a way in code to first detect if the column exists and if it doesn't create it in code?

It seems that on clicking datagridview column header, the column will be automatically sorted based on the column type. I have a column showing some numbers. If column type is string, it sorts "1","20","3" into "1","20","3". If column type is double, it sorts into "1","3","20" which is the result that I want. However, there might be some erros in the numbers and error messages(text) will show in the cell instead of numbers. So I cannot set the column type as double. I want to ignore these error messages and sort all the numbers. How can I do this?
Also, I need to add some background colors to different rows in datagridview. So in the column header click event, I call the bkgColor Sub to achieve this. My question is that how can I override the sorting method in this event?

I've been able to add my own non-bound columns to a DATAGRIDVIEW - such as a check box column.But I'm not seeing how to take a bound column and make that column be a combobox. Doesn't appear to allow that.Do I have to hide the real column and add a "fake" front-end column that I make a combobox?

Here's my code:

The thing is -- when I look at table amtdue, everything is actually saved there. I just don't understand why I'm getting the error, and so I can't proceed with what I have to do after clicking the btnaddtocart button.
