If the OptionsView's TreeListOptionsView.AutoWidth option is disabled, the control width can be less than the total width of columns. The control displays scrollbars in this case. The MakeColumnVisible method allows you to scroll to the required column from code.
The MakeColumnVisible method does nothing in the following cases:
In other cases, the method scrolls the control the minimum amount required to make the column completely visible on screen.
Note
When assigning a column to the FocusedColumn property, the specified column is automatically made visible using the MakeColumnVisible method. Thus, if you need to make a column visible and focus it, simply assign the desired column to the FocusedColumn property. The MakeColumnVisible method should be used when you don't need to move focus to the target column.
