How to change the row color on mouse hover in WinForms GridGroupingControl?
This article explains how to change the row color on mouse hover in WinForms GridControl.
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. Refer the below code snippet,
C#
//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();
}
VB
'Invoke the events to change the color of row during the mouse hover. Me.gridGroupingControl1.TableControlCellMouseHoverEnter += gridGroupingControl1_TableControlCellMouseHoverEnter Me.gridGroupingControl1.QueryCellStyleInfo += gridGroupingControl1_QueryCellStyleInfo Dim 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 hoverd 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
