Color selected line

[sve]

I want to color the selected line of a GridDataboundGrid in a particular color.

I try

private void gdg_CellClick(object sender, Syncfusion.Windows.Forms.Grid.GridCellClickEventArgs e)
{
gdg.Model.RowStyles[e.RowIndex].BackColor = System.Drawing.Color.Red;
gdg.Model.Refresh();
gdg.Refresh();
}

Thanks

You cannot ''set'' the backcolor of a row in a GridDataBoundGrid. Instead, you need to use an event to manage this. http://64.78.18.34/Support/article.aspx?id=561

If you always want to have the current row selected, you can set grid.ListBoxSelectionMode = SelectionMode.One. Then the selection color will be applied to the current row (as an overdrawn alphablended rectangle). You can control this alphablend color by setting grid.AlphaBlendSelectionColor.

Ok grid.ListBoxSelectionMode = SelectionMode.One works fine. However when my rowindex change programiticaly (with a currencyManager attach to a DataTable who''s populate my grid) the row isn''t underline.
Is there a special refresh to do ?

Ok, i use and event and it works fine.
Thanks.

You can handle the currencymanager positionchanged event.

CurrencyManager cm = (CurrencyManager) this.gridDataBoundGrid1.BindingContext[this.gridDataBoundGrid1.DataSource, this.gridDataBoundGrid1.DataMember];
cm.PositionChanged += new EventHandler(cm_PositionChanged);

In the handler, if the position change is from outside the grid, move the currentcell.

private void cm_PositionChanged(object sender, EventArgs e)
{
	if(!this.gridDataBoundGrid1.CurrentCell.IsInMoveTo)
	{
		CurrencyManager cm = sender as CurrencyManager;
		if(cm != null)
		{
			int row = this.gridDataBoundGrid1.Binder.PositionToRowIndex(cm.Position);
			this.gridDataBoundGrid1.CurrentCell.MoveTo(row, this.gridDataBoundGrid1.CurrentCell.ColIndex);
		}
	}
}

I am trying to undo the black color of the selected row in GridDataBoundGrid. I would like it to stay white. I tried setting e.Style.BackColor in the GDBG_PrepareViewStyleInfo event, but doesn''t seem to effect selected rows, they are still black.

Any info would be appreciated.

Hi Lev,

I do not know what black color you are trying to remove. Here is a code snippet to show setting e.Style.BackColor in the PrepareViewStyleInfo event that changes for the selected rows.

this.gridDataBoundGrid1.AlphaBlendSelectionColor = Color.Empty;
this.gridDataBoundGrid1.ListBoxSelectionMode = SelectionMode.One;
this.gridDataBoundGrid1.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.HideAlways;

this.gridDataBoundGrid1.PrepareViewStyleInfo += new GridPrepareViewStyleInfoEventHandler(gridDataBoundGrid1_PrepareViewStyleInfo);

private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
GridCurrentCell cc = gridDataBoundGrid1.CurrentCell;

// Highlight the current row
if (e.RowIndex > gridDataBoundGrid1.Model.Rows.HeaderCount && e.ColIndex > gridDataBoundGrid1.Model.Cols.HeaderCount
&& cc.HasCurrentCellAt(e.RowIndex))
{
e.Style.BackColor = Color.Pink;
e.Style.TextColor = SystemColors.HighlightText;
e.Style.Font.Bold = true;
}
}

Best regards,
Stanley
