How to change the row color on mouse hover in WinForms GridGroupingControl?

Change the row color

By default, the current record will be highlighted if record is selected. If you want to change the row color while hovering the mouse, it can be achieved by handling the TableControlCellMouseHoverEnter, TableControlCellMouseHoverLeave and QueryCellStyleInfo events. This article explains how to change the row color on mouse hover in WinForms GridGroupingControl. Refer the below code snippet.

//Invoke the events to change the color of row during the mouse hover.
this.gridGroupingControl1.TableControlCellMouseHoverEnter += gridGroupingControl1_TableControlCellMouseHoverEnter;
this.gridGroupingControl1.QueryCellStyleInfo += gridGroupingControl1_QueryCellStyleInfo;
 
void gridGroupingControl1_QueryCellStyleInfo(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs e)
{
    if (hoveredIndex == e.TableCellIdentity.RowIndex)
    {
        //Set the back color for the mouse hovered row.
        e.Style.BackColor = Color.LightBlue;
    }
}
 
void gridGroupingControl1_TableControlCellMouseHoverEnter(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs e)
{
    //Set the hovered row index to change the backcolor.
    hoveredIndex = e.Inner.RowIndex;
    this.gridGroupingControl1.TableControl.Refresh();
}

' Invoke the events to change the color of row during the mouse hover.
AddHandler Me.gridGroupingControl1.TableControlCellMouseHoverEnter, AddressOf gridGroupingControl1_TableControlCellMouseHoverEnter
AddHandler Me.gridGroupingControl1.QueryCellStyleInfo, AddressOf gridGroupingControl1_QueryCellStyleInfo

' Declare a variable to store the hovered row index
Private hoveredIndex As Integer = -1

Private Sub gridGroupingControl1_QueryCellStyleInfo(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableCellStyleInfoEventArgs)
    If hoveredIndex = e.TableCellIdentity.RowIndex Then
        ' Set the back color for the mouse hovered row.
        e.Style.BackColor = Color.LightBlue
    End If
End Sub

Private Sub gridGroupingControl1_TableControlCellMouseHoverEnter(ByVal sender As Object, ByVal e As Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCellMouseEventArgs)
    ' Set the hovered row index to change the backcolor.
    hoveredIndex = e.Inner.RowIndex
    Me.gridGroupingControl1.TableControl.Refresh()
End Sub
