GridListControl and selected row

[Administrator]

Hi together,

when I select an item in my gridlistcontrol - the item is highlighted (background blue colored) with a dotted rectangle.

How can I disable the dotted rectangle?

Cheers,
Markus

Try subscribing to the grid''s DrawCell event and reset the borders there.

this.gridListControl1.Grid.DrawCell += new GridDrawCellEventHandler(Grid_DrawCell);


private void Grid_DrawCell(object sender, GridDrawCellEventArgs e)
{
	e.Style.ResetBorders();
}

Hi Clay,

that works (the dotted line isn''t visible anymore). But now the text jumps (moves a little bit) when I highlight an iteam.

How can I stop that?

Try this.

private void Grid_DrawCell(object sender, GridDrawCellEventArgs e)
{
	GridControl grid = sender as GridControl;
	if(grid.CurrentCell.HasCurrentCellAt(e.RowIndex))
	{
		e.Style.ResetBorders();
		e.Style.BorderMargins.Top = 1;
		if(e.ColIndex == this.ListBox1.ImageColumn)
			e.Style.BorderMargins.Left = 2;
	}
}

Thank''s clay - that works

Sorry, I was too fast.

The text is still "jumping" when you highlight an item in the gridlistcontrol and then click on another control in the application?

You can check to see if the grid has focus before making the adjustment.

private void Grid_DrawCell(object sender, GridDrawCellEventArgs e)
{
	GridControl grid = sender as GridControl;
	if(grid.CurrentCell.HasCurrentCellAt(e.RowIndex))
	{
		e.Style.ResetBorders();
		if(grid.Focused)
		{
			e.Style.BorderMargins.Top = 1;
			if(e.ColIndex == this.ListBox1.ImageColumn)
				e.Style.BorderMargins.Left = 2;
		}
	}
}

Thanks Clay - great!!!

But one further question :-)) How can I get to the GridListControl object from

GridControl grid = sender as GridControl;

I don''t want to specify explicitly:

this.ListBox1.ImageColumn

cause I want to use this method for multiple gridlistcontrols.

Try casting grid.Parent to a GridListControl to see if that will do it.

I have this same problem with the dotted lines and gridgrouping control. I tried using a modified version of the code you suggested:
private void gcEmailGrouping_TableControlDrawCell(object sender,GridTableControlDrawCellEventArgs e)
{
e.Inner.Style.ResetBorders();
}
but the dotted lines remains.

Thanks,
Greg

What dotted lines are you trying to remove?

Can you tell us how to see the problem in one of our samples, or can you upload a sample project showing the problem, or maybe a picture marked up showing the lines you want to get rid of?

It is a solid line in the attached screen shots, but you can see it around the "From" column of the highlighted row. I have the grid set to select the entire row but the clicked cell still gets an outline. The second screen shot shows when a covered range is clicked to highlight the row. How can I change to color of the covered range to be highlighted?

I think the rectangle you are showing is the currentcell border. Try setting this property to remove it:

this.gridGroupingControl1.TableModel.Options.ShowCurrentCellBorderBehavior = GridShowCurrentCellBorder.HideAlways;

How to control the selection backcolor depends on selection architecture you are using. But here is one set of properties that gives you access to the selection color you see.

this.gridGroupingControl1.TableOptions.ListBoxSelectionMode = SelectionMode.One;
this.gridGroupingControl1.TableOptions.AllowSelection = GridSelectionFlags.None;
//	this.gridGroupingControl1.TableOptions.ListBoxSelectionColorOptions = GridListBoxSelectionColorOptions.DrawAlphablend;
this.gridGroupingControl1.TableOptions.SelectionBackColor = Color.Red;

Thanks Clay, the cell borders are gone, but I don''t think I asked my second question very well.
How can I make the covered range (mailicon) in a row change it''s background to be highlighted when the row is selected?

Is the white part of the bitmap?

If the white is part of the bitmap, then you can try setting a transparent color for the bitmap. But if that does not work, the only way I would know to do it is to use alphablending instead drawing the background.
