PRB: Incremental Search with Grid Causes Screen Flicker

MORE INFORMATION

Steps to Reproduce Behavior

1. Create a Form, and set the LockScreen property to False (.F.).
2. Add the Customer table, in the home()+"SAMPLES\DATA" folder, to the Data Environment. By default, the table is added to the Data Environment with the Name "cursor1". Set the Order property of the cursor to "cust_id".
3. Drag the table onto the form to create a grid. Set the Name property of the Grid to "Grid1".
4. Add a TextBox control to the form. Make sure that SelectOnEntry property of the Textbox control is set to .F. (the default). Add the following code to the TextBox control's InterActiveChange event:

         SELECT customer
         SEEK UPPER(ALLTRIM(This.Value))
         ThisForm.Grid1.Refresh
   							

5. Run the Form and type a few characters in the text box.
6. Although the REFRESH method of the grid is being called from Text1.InterActiveChangeEvent, the record pointer in the grid does not move to the correct record.
7. Now change the code in Text1.InterActiveChange event as follows:

         SELECT customer
         SEEK UPPER(ALLTRIM(This.Value))
         ThisForm.grid1.SetFocus
         ThisForm.text1.SetFocus
   							

8. Repeat step 5.
9. Now the Record Pointer in the grid is moving correctly but there is a lot of screen flicker every time a character is entered into the text box.
