Delete DropDownList selected item

[Larry]

I am using a DropDownList in a Grid.    I have nullable fields using the DropDownList.   I am having a problem deleting items that have been selected in the DropDownList.    Here is an example.    We have a nullable field for DepartmentID in a table and we have entered and saved data using the DropDownList.   Now we want to delete the DepartmentID field (or make it null again).   I have tried using the {delete} key, but that does not work.   I have tried trying to capture the {delete} key on the KeyPress in JavaScript and manually change the DepartmentID, but the {delete} key gets trapped before getting to my JavaScript so I cannot do it from JavaScript.    How do you reset the DepartmentID field back to Null?

Thanks, Larry

Hello Larry,

I am not sure I understand the scenario correctly. If you would like to change the value of some of the row's fields, then I would suggest passing the <tr> element to the Grid's dataItem method and then using the set method to modify it. For example: 

var item = grid.dataItem(grid.tbody.find("tr:first")); //the first row;
item.set("DepartmentID", null);
