Combobox Default

Hi Folks,

I'm trying to configure a combobox. The user should have two options:

- either to select a value from the dropdown (items come from a connected Excel table), however if

- the user has a barcode, the value is stored in a variable. I then set the combobox default value to that variable value. But the problem is that nothing happens, except that now the dropdown contains only 1 selectable value (the first one from the connected table)

Any ideas what I'm missing here?

HI,

I think I would take a step out. Load the barcode control then set the drop down default to the Barcode Value. May have to put an if statement in the default value statement to where if no barcode then blank.

Hi @TJO :
Do you want to set a Combo box control's default options?
First of all, the following points need to be noted:
If you need to set a Combo box control's default options, you need to set its DefaultSelectedItems property.
The items selected in DefaultSelectedItems must be records in the Combo box control's items property.
So if the barcode is not in the data source of the combo box, then you need to reconstruct the combo box’s items property.
Second,If the problem cannot be solved, could you provide more detailed information?
The data structure of the data source.(table name,field name,date type)
The combo box's items property and DefaultSelectedItems property.
What is the barcode?
What is the variable?
Best Regards,
