Matrix Style Udo- data delete before

[former_member499436]

Hi,

I have created matrix style Udo.

I call it from menu with this code.

SAPbouiCOM.Form frm1= Application.SBO_Application.OpenForm(SAPbouiCOM.BoFormObjectEnum.fo_UserDefinedObject, "T_UDOSample1", "");

Now i want to call some validation before data delete. If this data is used anywhere i want to show an error message.

For example i have 3 record in matrix. "a", "b","c"

I remove data "a" and "b" with right click /remove button, but until update button clicked these data is not deleted.

When i click the update button i want to get "a" and "b" is signed for deleting. But i cant find any flag about this.

How can i get these data.

Thanks.
