Click a Check Box to Run a Macro
In the last post, we set up a To Do list with check boxes. Each check box is linked to a cell that’s 2 columns to the right, and we used a macro to set that up quickly.
Today, we’ll create a macro that puts today’s date in the Date column, if you check a box in column B.
Create the Date Macro
The macro will be relatively simple.
- We have to figure out where the check box is, when it’s clicked.
- Then, we’ll find the cell that’s two columns to the right.
- In that cell, we’ll enter the current date, if the check box is checked.
- If the check box was cleared, we’ll clear the date cell.
Here is the code, which uses Application.Caller to identify which check box was clicked. If the box is checked, its value is 1, and we’ll put in the date.
Sub CheckBoxDate() Dim ws As Worksheet Dim chk As CheckBox Dim lColD As Long Dim lColChk As Long Dim lRow As Long Dim rngD As Range lColD = 3 'number of columns to the right for date Set ws = ActiveSheet Set chk = ws.CheckBoxes(Application.Caller) lRow = chk.TopLeftCell.Row lColChk = chk.TopLeftCell.Column Set rngD = ws.Cells(lRow, lColChk + lColD) Select Case chk.Value Case 1 'box is checked rngD.Value = Date Case Else 'box is not checked rngD.ClearContents End Select End Sub
Assign the Macro to a Check Box
First, we’ll see how to manually set up the check box so it runs the CheckBoxDate macro.
- Right-click the check box in cell B4, so the pop-up menu appears (if the Move/Copy popup appears, try right-clicking again)
- Click the Assign Macro command
In the list of macros, click CheckBoxDate, then click OK
Test the Date Macro
To test the macro, follow these steps:
- Click away from the check box, to deselect it
- Click the check box, to add a check mark, and the current date should appear in the date column
- Click again, to remove the check mark, and the date cell should be cleared.
Use VBA to Add Macros to All Check Boxes
Instead of manually assigning a macro to each check box, we’ll create a macro that’s similar to the one we used to link all the check boxes to a cell.
In the macro, we’ll set the OnAction property to the date macro name
Sub SetCheckBoxesMacro() Dim chk As CheckBox For Each chk In ActiveSheet.CheckBoxes chk.OnAction = "CheckBoxDate" Next chk End Sub
Run the Add Macros Code
To assign the CheckBoxDate macro to each check box, run the SetCheckBoxesMacro macro.
You won’t see a change on the worksheet, but now each check box has the macro assigned to it.
To test the results, click on any one of the check boxes, and the Date cell in that row should change.
