In this example, if Fruit is selected as the Category, only Fruit appears in the Item drop-down list. Video: Dependent Data Validation In this dependent data validation example, if a country is selected from the first drop down, only that country's cities appear in the next column's drop down list. However, you can use the Excel IF function to make the selection more flexible. If no country is selected, the City column will show a list of world cities in the dependent drop down list.
Create Named Lists Start by creating Named Lists, which will be the choices in the dependent data validation drop down lists. Test the Dependent Data Validation Click on a cell in the Category column, and select either Fruit or Vegetable, from the Produce drop down list.

Posted on January 31st, 2012 in Excel Howtos , Huis , Posts by Hui - 35 comments In the past here at Chandoo.org and at many many other sites, people have asked the question “How can I display a number Multiplied or Divided by 10, 100, 1000, 1000000 etc, but still have the cell maintain the original number for use in subsequent calculations“.
Typically the answer has been limited to “It can’t be done” or “It can only be done in multiples of 1000”. Well thanks to a tip I picked up from Kyle who responded to a post here at Chandoo.org they are all wrong. It is possible to Multiply or Divide any cell contents by any power of 10 using Custom Number Formats ! That is: How does this work: When using custom number format we have two possibilities to modify the display number Use a Comma to divide by 1000; orUse a % to Multiply by 100 So using a combination of these any power of 10 can be obtained. So using the correct combination of , and % can result in any power of 10 multiplier we require.
Status Bar. The status bar portion of the Excel screen gives you a simple and convenient method do display message to the user.
You can use it to display the progress of a VBA procedure, or indicate that the procedure is complete. The code to put a message on the status bar is shown below. Application.StatusBar = "Procedure Complete" To return control of the status bar back to Excel, set its value to FALSE. Application.StatusBar = FALSE When you use the status bar to display a message to the user, that message will be displayed until your code returns control of the status bar back to Excel.
To get around this, you can use an OnTime procedure to clear the status bar after some number of seconds. How to speed up calculation and Improve performance of Excel and VBA. The key to increasing speed of calculation and improving performance of your excel worksheet and VBA code lies in understanding how Excel calculates (and re-calculates) each cell and resolves dependencies.
Whenever an event occurs that causes Excel to recalculate (for example a cell is changed, a VBA code calls for re calculation or anything else), the entire calculation process is carried out roughly as follows: 1.
