Stop Matrix flickering

[former_member275826]

Dear all,

I have written the code on list focus of column. Due to which whole matrix gets flicker.

Also i have used the "Freeze", but there is no use of this functionality.

 oForm = SBO_Application.Forms.GetForm(pVal.FormTypeEx, pVal.FormTypeCount);
  oForm.Freeze(true);
  oMatrix = (SAPbouiCOM.Matrix)oForm.Items.Item(pVal.ItemUID).Specific;
  Barcode = ((SAPbouiCOM.EditText)oMatrix.Columns.Item(pVal.ColUID).Cells.Item(pVal.Row).Specific).Value;
   oRecord = oDAL.returnReocord("SELECT U_BARCODE,U_ITEMCODE,U_WHSCODE,U_BIN,U_STKQTY,U_Batchnum FROM [@BSTK]        WHERE U_BARCODE='" + Barcode + "'", oCompany);
   if (!oRecord.EoF)
    {
    ((SAPbouiCOM.EditText)oMatrix.Columns.Item("1").Cells.Item(pVal.Row).Specific).Value = oRecord.Fields.Item("U_ITEMCODE").Value.ToString();
    ((SAPbouiCOM.EditText)oMatrix.Columns.Item("24").Cells.Item(pVal.Row).Specific).Value =   oRecord.Fields.Item("U_WHSCODE").Value.ToString();
     }
    oForm.Freeze(false);

Can anybody suggest me is there anyway to tackle this situation.

Hi Pravin,

What event is 'list focus of column' ?

if this event supports before and after event.

Try to put the form.freeze(true) in the before event.

And form.freeze(false) in the after event.

But do becarefull to handle any exception to un freeze the form since the form freeze in between two events.

Regards

Hi Pravin,

Is this System Form or your user form ?

if it is the later, set the matrix data directly through its data source.

Hi Edy,

its system form.

Hi Pravin,

I suppose this matrix is also a system matrix ?

Then your only choice might be to move your code into the Validate Event.

Put the Freeze on Before Validate and Unfreeze it on After Validate.

Hi Edy,

i have used the validate event but now sap gets crashed.

Hi Pravin,

Can i see your code where you catch this validate event?

Make sure that you have catch specific cell only.

If you didnt do that, when you set the value of itemcode and warehouse, it will trigger another validate event.

When that happens, you will be caught in an infinite loop until SBO ran out of memory and crash.
