Displaying an empty cell in Child combo

Hello Ellen,

You can use ClearSelection() method to display an empty cell. Here is the following code:

function DoClear()
{
   var combo = ISGetObject("wcProduct");
   combo.ClearSelection();
}

Invoke this script using button or any control you like. It will clear the selection you made in the combo.

Hope this helps. Thank you.

Displaying an empty cell in Child combo

I have two linked bound combos: Parent and Child. I select a row in a Parent combo and then Child combo is populated, but nothing is displayed first. Then I select a row in a Child combo. Then, I want to unselect a row is a Child combo (display an empty cell). If I delete the content of the cell and leave the cell (loose focus), the previously selected cell is displayed. How to unselect everything (display an empty cell) in a Child combo? Thanks, Ellen.
