Datagridview rowvalidating example

Hi Muthu, I was not able to reproduce the described issue using our latest release - Q3 2012.

Maybe there is something specific in your application.

Please, open a new support ticket and send us your project.

The following code example demonstrates how to use this event to perform a programmatic sort that emulates the default behavior of clicking a Data Grid View Column Header Cell when the default behavior has been disabled.

In this example, the is set to Column Header Select, so clicking the Data Grid View Column Header Cell selects the contents of the column.

For the example code to function as intended, the default column header click behavior needs to be changed each time the data is loaded into the Data Grid View.

By using Cell Formatting you will probably make it impossible for users to manually edit the combo box.

It is usually best to do this sort of work in the Data Binding Complete event (if you only want it done once) or during some event like Default Values needed or Row Validating.

The value "1" in the ID column corresponds to the value "Second" in the Items column. Sorry for my English and my newbie code :) Lastly, do not use the Cell Formatting event here - this event is not intended for this sort of use.When a column heading is clicked in a Data Grid View, the default behavior is to order the grid rows based on the clicked column, or to reverse the sort order if the grid is already sorted by the clicked column.private void Form1_Load(object sender, Event Args e) { Data Grid View Combo Box Cell combo Box Cell = new Data Grid View Combo Box Cell(); data Grid View1. you need to ensure that the value you set (in this case 1) is a value from your datatable id column. In the simple Combo Box I know a property Selected Index. @Stepler although I just tried this in the Cell Formatting event and it works unless the value you set does not match the datatable. Display Member = "Item"; } How can I programmatically set the value in the cell when the form loads? @Stepler don't set the value during the formatting event (This will probably make it impossible to change the value manually or do something equally weird) - it is usually best to do in the databindingcomplete event. And are you sure that the value you are setting is in the datatable id column?
