Keep reading to learn how to retrieve the selected slicer values in Section 7.

Retrieving the Selected Slicer Values

After initializing the slicer change event handler, the next step is to retrieve the selected values from the slicer using VBA code. This process involves identifying the slicer object and capturing the selected items into an array or variable for further processing.

Step-by-Step Guide

Follow these steps to retrieve the selected slicer values:

  1. Declare a variable to store the slicer object.
  2. Assign the slicer object to the declared variable. You can use the ActiveWorkbook.SlicerCaches property to get a list of all slicers in the workbook and then specify the name of the slicer you want to retrieve the values from.

    Example:
    Dim mySlicer as SlicerCache
    Set mySlicer = ActiveWorkbook.SlicerCaches("Slicer_Date")

  3. Declare an array or variable to store the selected slicer values.
  4. Loop through the SlicerItems collection of the slicer object and use the Selected property to determine if the item is selected or not. If an item is selected, add its value to the array or variable you declared in step 3.

    Example:
    Dim selectedItems() As Variant
    For Each item In mySlicer.SlicerItems
    If item.Selected Then
    ReDim Preserve selectedItems(index)
    selectedItems(index) = item.Value
    index = index + 1
    End If
    Next item

You can now use the retrieved slicer values for further calculations or to update other PivotTables or charts in your workbook based on the selection made by the user.

Performing Actions Based on Slicer Change

After retrieving the selected slicer values, it's time to perform specific actions or calculations based on the changes. In this step-by-step guide, we will show you how to incorporate conditional statements and execute desired actions when the slicer selection changes.

First, determine the action you want to perform. It could be as simple as changing the color of a cell or updating a chart. Let's say we want to update a PivotTable based on the selected slicer value. Here's how:

Code Description
Private Sub Slicer_Change() Triggered when the slicer selection changes
Dim selectedValue As String Declare a variable to store the selected slicer value
selectedValue = ActiveWorkbook.SlicerCaches("Slicer_Name").SlicerItems(Index_Number).Value Retrieve the selected slicer value
With ActiveSheet.PivotTables("PivotTable_Name").PivotFields("Field_Name") Reference the PivotTable and the desired field
.ClearAllFilters Clear all current filters
.CurrentPage = selectedValue Set the current page to the selected slicer value
End With End the With statement
End Sub End the Sub procedure

In the above code, replace "Slicer_Name," "Index_Number," "PivotTable_Name," and "Field_Name" with the appropriate names in your workbook.

With this code, the PivotTable will automatically update based on the selected value from the slicer. This approach can be customized to perform any action you want, depending on the data and analysis requirements.
