Description

An example demonstrating how to check the current mouse-hovered PivotGroupElement, in which RowGroupDescription is located.

Solution

We can subscribe to the ScreenTipNeeded event of the RadPivotGrid control. In the event handler, we can get the currently hovered item. If it is of type PivotGroupElement, we can check if the Data.Axis property is Rows and uses the Data.Group.Level property to extract the corresponding RowGroupDescription from the RowGroupDescriptions collection of the RadPivotGrid.

Sample Implementation

    private void Pivot_ScreenTipNeeded(object sender, Telerik.WinControls.ScreenTipNeededEventArgs e)
    {
        PivotGroupElement cellGroup = e.Item as PivotGroupElement;
        if (cellGroup != null)
        {
            RadOffice2007ScreenTipElement screenTipGroupCell = new RadOffice2007ScreenTipElement();
            screenTipGroupCell.CaptionLabel.Text = "";

            if (cellGroup.Data.Axis == PivotAxis.Rows & this.RadPivotGrid1.RowGroupDescriptions.Count - 1 >= cellGroup.Data.Group.Level)
            {
                var rowGroupDescriptor = this.RadPivotGrid1.RowGroupDescriptions[cellGroup.Data.Group.Level];
                screenTipGroupCell.MainTextLabel.Text = rowGroupDescriptor.DisplayName;
                screenTipGroupCell.FooterTextLabel.Text = "";
                cellGroup.ScreenTip = screenTipGroupCell;
            }
        }
    }

    Private Sub Pivot_ScreenTipNeeded(sender As Object, e As Telerik.WinControls.ScreenTipNeededEventArgs)
        Dim cellGroup As PivotGroupElement = TryCast(e.Item, PivotGroupElement)
        If cellGroup IsNot Nothing Then
            Dim screenTipGroupCell As RadOffice2007ScreenTipElement = New RadOffice2007ScreenTipElement()
            screenTipGroupCell.CaptionLabel.Text = ""

            If cellGroup.Data.Axis = PivotAxis.Rows And Me.RadPivotGrid1.RowGroupDescriptions.Count - 1 >= cellGroup.Data.Group.Level Then
                Dim rowGroupDescriptor = Me.RadPivotGrid1.RowGroupDescriptions(cellGroup.Data.Group.Level)
                screenTipGroupCell.MainTextLabel.Text = rowGroupDescriptor.DisplayName
                screenTipGroupCell.FooterTextLabel.Text = ""
                cellGroup.ScreenTip = screenTipGroupCell
            End If
        End If
    End Sub
