How to clear combobox

[Former Member]

Hi All,

I want to fill my combobox on the basis of values selected in other combobox. For this I have to Clear the combobox. I have used Remove method with SAPbouiCOM.BoSearchKey.psk_Index.

But its giving error. Whats the process to Clear Combobox.

Thanks,

Hi ,

You can use the below code.

int Count = oComboBox.ValidValues.Count;           

for (int i = 0; i < Count; i++)

            {

                oComboBox.ValidValues.Remove(oComboBox.ValidValues.Count - 1, SAPbouiCOM.

BoSearchKey.psk_Index);            

            }

Cheers,

Hello anuj singh,

this is how it works here since a long time:

        Do While oComboBox.ValidValues.Count > 0
            oComboBox.ValidValues.Remove(0, SAPbouiCOM.BoSearchKey.psk_Index)
        Loop

On every Remove the indexes are shifting so the save method is to use always index=0

Another way could be to Remove from end and then backwards through the indexes. Then the lower indexes stay the same while removing.

Yes, of course.

My mistake!

Anuj,

Should work this way.

      Dim item As SAPbouiCOM.Item = YourItem
      Dim itemCombo As SAPbouiCOM.ComboBox = item.Specific
      For index As Integer = 0 To itemCombo.ValidValues.Count - 1
        itemCombo.ValidValues.Remove(index, SAPbouiCOM.BoSearchKey.psk_Index)
      Next index

Hello,

There is a small problem with this code. As the loop progresses, the value of index increases whereas the index value of validvalues keeps on decreasing with every deletion. So, if there are 5 values, by the time the index reaches 4, the validvalues index is only 1.

Make following modifications in the code:

      Dim item As SAPbouiCOM.Item = YourItem
      Dim itemCombo As SAPbouiCOM.ComboBox = item.Specific
      For index As Integer = 0 To itemCombo.ValidValues.Count - 1
        itemCombo.ValidValues.Remove(0, SAPbouiCOM.BoSearchKey.psk_Index)
      Next index

Hello anuj,

I think you can solve your problem by using the object ValidValues and the methode remove.
