Type	Description
Boolean	true if the comparison is displayed; otherwise, false

Remarks

The VGridControl allows you to compare records if the AllowRecordComparison property is set to true.

The ShowComparison method displays the records that were added to the comparison.

To add records to the comparison, use one of the following actions:

• Tick the checkboxes in record headers.
• Right-click a record header and choose Add to Comparison from the context menu.
• Use the AddToComparison method, and the AddSelectionToComparison method.

Example

The following example uses the AddToComparison method to add records to the comparison collection, and the ShowComparison method to display the comparison.

C#

using DevExpress.XtraVerticalGrid;

private void btnAddRecordsAndShowComparison_ItemClick(object sender, DevExpress.XtraBars.ItemClickEventArgs e) { 
    // Add records to the comparison collection.
    vGridControl1.AddToComparison(5);
    vGridControl1.AddToComparison(7);
    // Display the comparison.
    vGridControl1.ShowComparison();
}

VB.NET

Imports DevExpress.XtraVerticalGrid

Private  Sub btnAddRecordsAndShowComparison_ItemClick(ByVal sender As Object, ByVal e As DevExpress.XtraBars.ItemClickEventArgs)
    ' Add records to the comparison collection.       
    vGridControl1.AddToComparison(5)
    vGridControl1.AddToComparison(7)
    ' Display the comparison
    vGridControl1.ShowComparison()
End Sub

To get the indices of the records in the comparison, use the GetComparisonRecords method.

The HideComparison method hides the comparison. To clear the comparison collection, use the ClearComparison method.
