UI: Simulating Click on Search button

Hello,

we are trying to open the material form (150) with a specific item number.

We open the form in search mode, put the number into the itemcode field and then want to submit the form by simulating an item click event of the search button:

form.Items.Item(1).Click(SAPbouiCOM.BoCellClickType.ct_Regular)

At this point the program crashes.

Any ideas?

Thanks for your help,

Frank
