Dealing with select boxes

[mmurdock]

I'm trying to do something like this in a form

varTest = cboAbsenceCode.SelectedKey

I get the following error:

Conversion from type 'Byte()' to type 'String' is not valid.

How do I handle this?

Thanks,

Mat

Hi Mat,

Please open attached report in the Demo.exe sample application.

Thank you.

Thank you for that, but I would like to know the combo box's selected key. I seem to be able to get this if the key is a string, but if the key is an integer then I seem to have a problem.

Hello,

You can use following expression:

Code: Select all

ComboBoxControl1.Control.SelectedKey

Thank you.

if I try this:

Code: Select all

varTest = cboAbsenceCode.Control.SelectedKey

I get this error: "error BC30456: 'SelectedKey' is not a member of 'System.Windows.Forms.ComboBox'."

If I try this:

Code: Select all

varTest = cboAbsenceCode.SelectedKey

I get this error:

Conversion from type 'Byte()' to type 'String' is not valid.

I need the key value.

Thanks,

Mat

It would seem that this works for you except for a type conversion problem. Have you tried the following? Just my two sense... I haven't really checked it out.

Code: Select all

varTest = cboAbsenceCode.SelectedKey.ToString()
