However, it still throws this Exception when the DataGridViewImageColumn in the new Row becomes visible. There are two workarounds that worked for me: Uncheck the "Enable Adding" option in the Designer - then add rows programmatically - using buttons etc. - I think this is what I did first time round. Handle the DataError Event of the DataGridView like this: private void dataGridView1_DataError(object sender, DataGridViewDataErrorEventArgs e) { if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value == DBNull.Va

Posted on 24/03/2007 by ksb Another fairly hard-core post on .Net today, so if you don't program in C# .Net, you can probably ignore this! Recently, I have started playing with integrating databases into C# for the first time. I've done a little bit of data binding before, but I've never used the DataGridViewControl until this week. I've been doing what I would consider to be very simple stuff, but had hit a brick wall recently that has sucked up hours of my time. It's times like this that I really miss having colleagues and friends who are working on the same technologies as me, because I'm sure that anyone who's used ADO and this control for more than a little while will probably know all about how to fix it and so on. Anyway, I was developing a ‘lookup' field from a grid; that is, the underlying data required a numeric id to identify another record; but no-one can remember what number identifies a supplier… so you really want an easier way to set that value. The result of the process is something like the image shows below; instead of showing a numeric ‘SupplierID', you provide a drop-down-list of the various company names. Now, behind the scenes, the system knows the company name and the associated Supplier ID, and it uses the latter to populate the database. Lovely stuff. But I was doing my own project with my own data, so looking at various resources, I simply emulated their approach to replicate this effect. I rapidly started experiencing the following error messages: "The following exception occurred in the DataGridView: System.ArgumentException: DataGridViewComboBoxCell value is not valid." and the associated dialog is here: I was getting these messages as I closed the form! I could change data at will and save it, so logically it seemed like my code must be ‘right' because I could prove the data updates were happening ok; and that s
