ToolTip does not work correctly on Gauge

Good morning,
I use a ToolTip on a Gauge control created by code:

Dim rg As New Syncfusion.Windows.Forms.Gauge.RadialGauge
rg.GaugeLabel = (HOccupate + HPreventivo + HLibere).ToString
rg.MinimumValue = 0
rg.MaximumValue = HOccupate + HPreventivo + HLibere
rg.Size = New Size(200, 200)
rg.EnableCustomNeedles = True
rg.MinorInnerLinesHeight = 0
rg.MinorTickMarkHeight = 0
HRitardo = HRitardo - (HOccupate + HPreventivo + HLibere)
If HRitardo < 0 Then
    HRitardo = 0
End If
If HRitardo > 0 Then
    rg.BackColor = Color.Red
    Me.ToolTip1.SetToolTip(rg, "occupate: " + HOccupate.ToString + CR + "offerte: " + HPreventivo.ToString + CR + "libere: " + HLibere.ToString + CR + "RITARDO: " + HRitardo.ToString)
Else
    rg.BackColor = Color.Gray
    Me.ToolTipGauge.SetToolTip(rg, "occupate: " + HOccupate.ToString + CR + "offerte: " + HPreventivo.ToString + CR + "libere: " + HLibere.ToString)
End If

To view the ToolTip, I have to click on the Gauge. Should the ToolTip not be displayed when the mouse is over the control? (without clicking).

The same problem also occurs when using SuperToolTip.

My program runs on Windows10.

Kind Regards

Beppe

Hi Mallika,
sorry but I forgot to say that the Gauge is on a GridControl.
Maybe this is what causes the problem?
I am attaching a screenshot.
Thank you.
Beppe

Hi Beppe, 
 
Thanks for the update. 
 
We can understand your scenarios. By default, GridControl have the direct support to show the tooltip text and to set tooltip for a cell, use CellTipText property for specific cells or specific columns or specific columns. If you want to display tooltip text for grid cells based on conditions, CellTipText property can be used in QueryCellInfo event. please refer to the below code snippet and UG documents, 
 
Code Example 
//Set the ToolTip text for particular cell. 
this.gridControl1[1, 1].CellTipText = "Hello"; 
 
//Adding ToolTip to the specific column 
this.gridControl1.ColStyles[1].CellTipText = "Hello"; 
 
//Adding ToolTip to the specific row 
this.gridControl1.RowStyles[2].CellTipText = "Hello"; 
 
this.gridControl1.QueryCellInfo += gridControl1_QueryCellInfo; 
 
void gridControl1_QueryCellInfo(object sender, GridQueryCellInfoEventArgs e) 
{ 
    // Enabling comment tip for particular cell. 
    if (e.RowIndex == 1 && e.ColIndex == 1) 
        e.Style.CellTipText = "Cell comment"; 
 
    // Enabling comment tip for row. 
    if (e.ColIndex > 0 && e.RowIndex == 5) 
        e.Style.CellTipText = "Row comment"; 
 
    // Enabling comment tip for column. 
    if (e.RowIndex > 0 && e.ColIndex == 4) 
        e.Style.CellTipText = "Column comment"; 
} 
 
 
Moreover, please refer the below KB documents for showing SuperToolTip and ToolTip in grid.
