clearing combobox in UDO header

[Former Member]

Hi all,

I'd like to post this strange behaviour happening inside a user defined form for UDO processing.

i have the following code to clear each combobox in the UDO header:

cmbBPCode.get_ValidValues().Add("0", " ");

cmbBPCode.Select(" ", SAPbouiCOM.BoSearchKey.psk_ByDescription);

cmbBPCode.get_ValidValues().Remove(" ", SAPbouiCOM.BoSearchKey.psk_ByDescription);

cmbStatus.get_ValidValues().Add("0", " ");

cmbStatus.Select(" ", SAPbouiCOM.BoSearchKey.psk_ByDescription);

cmbStatus.get_ValidValues().Remove(" ", SAPbouiCOM.BoSearchKey.psk_ByDescription);

SAPbouiCOM.Form oForm = SBO_Application.get_Forms().get_ActiveForm();

SAPbouiCOM.Item oItem = oForm.get_Items().Item("txtCode");

oItem.set_DisplayDesc(true);

oItem = oForm.get_Items().Item("cmbStat");

oItem.set_DisplayDesc(true);

oForm.Refresh();

oForm.Update();

I need to do that beacuse after adding data into UDO tables, the combobox still holds the previous value.

In other words i got all the form fields cleared except for the combobox in the UDO header.

The above code solved the problem but shows the 0 value rather than the blank description in the combobox!

Is it the only way to do that?

Can anyone help me?

i solved using the following code:

oForm.Close();

DrawForm(); // load the form xml file

Andrea,

David,

simple close and re-open the form each time i add to UDO tables.

Hi Andrea,

i think i got the problem now

you use

oItem.set_DisplayDesc(true);

after you set the value.

do the following

when you load the UDO from a xml be sure that you set DisplayDesc already in screen painter

or set it when you load the xml in et_Form_load event.

that should do it ... i pray

David,

In the form xml file the DisplayDesc attribute is set to false as i want.

I'll try to set it to true in the et_Form_load event.

For sure I'll let you know the result.

thx

David,

here is my code:

if (pVal.get_EventType() == SAPbouiCOM.BoEventTypes.et_FORM_LOAD && pVal.get_Before_Action() == false)

{

SAPbouiCOM.Form oForm = SBO_Application.get_Forms().Item(FormUID);

SAPbouiCOM.Item oItem = oForm.get_Items().Item("txtCode");

oItem.set_DisplayDesc(true);

oItem = oForm.get_Items().Item("cmbStat");

oItem.set_DisplayDesc(true);

}

but i got the following error:

"Invalid item [66000-3] for Item Unique Id: txtCode

it seems the form is not loaded yet when I catch the event!

Hi Andrea,

your problems get stranger and stranger

the only thing i see is that you don't look for the right ItemUID in your If Statement.

If pval.FormUID == "myFormUID" AND ...

now your code works for every form that opens.

alternative:

please just try shortly to set the DisplayDesc (for one Test) in the XML with Screenpainter.

David,

Just to inform you I set the DisplayDesc attribute to true in the XML for the items, but nothing changed.

Actually I see the description rather than the code value in the combobox, but after data insert i still see the 0 value rather than the blank description.

Andrea

[Nussi]

that can't be true

i use this already for months and it works perfectly.

any other member here can help Andrea ?

David,

Maybe I have miss something...

Did you have the same problem for header combobox clearing?

Hi,

After adding the data, Set the value for that combo as shown below for that dbdatasouce.

oDBs_Head.SetValue("ComboID", 0, "")
