After some experiments the final UDF looks like: We used this feature to build an UDF which will trigger sheet calculation.

We realized that the UDF wrapped to a named formula will be evaluated together with the named formula.Įxample 4 - Trigger calculation: format change, column width change You can read in this post that column width change and most of the cell-format changes triggers charts to call the named formulas to be calculated (evaluated). (But we must highlight one obvious advantage: that you can simply copy the cell, the UDF technique will work anywhere in your file - no need to change/set up new Worksheet_Change events.) We do not want to encourage anyone to use this “illegal” UDF. You can say that this is possible without tricks, using Worksheet_change event. Remember that Application.Caller is the cell from which we started the validation. And when you click on the small arrow, the magic happens: before choosing the new value, the UDF writes the old value to the cell left to the active cell - as it is set by the (0, -1).Value statement. This name will be the list we use in the validation. Using this name (with relative reference to the active cell): The UDF is called by the active cell, but it runs, so the deletion happens!Įvaluate named formula from VBAIn the next step we used the UDF in named formulas to make easier to put value into the cell, instead of the #VALUE error. In Excel 2007 the Evaluate dialogue works differently.

How to Create a Rollover Effect in Excel: Execute a Macro When Your Mouse is over a Cell and The Excel Rollover Mini FAQ You can read the details of this ingenious technique here: If the Windows mouse rollover event is the caller, the UDF will run and do whatever you coded into it. Method 1 - Mouse rolloverThe first method we have seen is the mouse rollover technique by Jordan Goldmeier. So we should try to find other methods to call an UDF. Maybe Excel watches only if the caller is a cell or not - it seems the code stops running only if we try to alter a sheet from an UDF called from a cell. The formula is always entered to a cell or cells on a worksheet, so this way the caller (which calls the UDF, so makes it run) is the cell itself. However there are some workarounds to bypass this limitation. This is the normal way of working according to Microsoft’s design goal. Your UDF will simply go to error and stop immediately if you code anything forbidden into it. We know that User Defined Functions (UDF) are not allowed to directly change values/properties in any cell, worksheet, or workbook - they must only return a value, as any other Excel built-in formula does.
