Please find attached a sample project. 1. Select the new row and activate te editor. 2. Do not enter any value and click outside the new row. The exception is thrown. Workaround: bind directly to the query result: this.radGridView1.DataSource = (from p in context.Customers select p).ToList();
The fix about GridViewComboBoxColumn will be included in R2 2016 SP1 version.
You can find attached a runnable project which reproduces the error when following the steps from the gif file.
Hello Sarah, Thank you for writing. Indeed, the issue is still reproducible for GridViewComboBoxColumn. I have updated the feedback item's status. We will investigate the precise case and we will try to introduce a fix as soon as possible. Feel free to use the suggested workaround. Regards, Desislava
I am still getting the data exception for the new row where the cell is a dropdown. My datasource is a BindingSource and I prefer not to rewrite all my code. Thanks.
