Code For The DataWindow Control

Write the following code for the Clicked event of the dw_left control:

// Object: DW_left in uo_shuffle_rows_between_2_dws // Event: Clicked If Row > 0 Then cb_transfer_to_right.Enabled = TRUE Else cb_transfer_to_right.Enabled = FALSE End If

This simply checks if any rows are selected in the control and enables or disables the cb_transfer_to_right CommandButton accordingly. The logic for the other DataWindow control is exactly the same.

The script for both the DataWindows are identical, so, we can implement the script in a function and distinguish between them by passing relevant parameters and then call it from both the DataWindows.
