Adding new value to GridViewComboBoxColumn

[Suman Rao]

Any one in Forum can answer the below requirement ?

We have requirement to add value for existing GridViewComboBoxColumn values
Basically GridviewComboBoxColumn is bind to Person DTO -> PersonName (This DTO is coming from Ria Domainsource)

The drop down column contains value Name1 and Name2 and it is editable column

But the requirement is to add value in the drop down if the value don't exist in the drop down
So we need add Name3 to Drop down and the new value need to save database using Ria DomainSource

Currently, I need a code sample to do this. We are not able add new value to existing drop down value
We are getting exceptions on editing the drop down as "Input is not in a correct format."

Is there a way, we add the value to the existing drop down

Thanks in advance

Hi Suman Rao,

I am attaching an example of how you can achieve the desired behavior.
It has a combo box column , and some code to allow the user to enter a new value to the combo column  source by typing it in the editable combobox.

All the best,
