GridSelection

[sve]

Hello, i have a gdg attached to a CurrencyManager and i use "PrepareViewStyleInfo" event for color my selected line.

I want only columns can be selected (no multiple lines, no multiple cells) but i want to be able to click on a line (cell) to raise an event and retrieve my row in the code.

So i use the code:
gdg.AllowSelection = GridSelectionFlags.Column | GridSelectionFlags.AlphaBlend | GridSelectionFlags.Multiple;

It works fine but i have always the selected line active (sometimes my current row, sometimes not so i have one line colored by selection and another by my code in "PrepareViewStyleInfo")

I want to disable the selected line is it possible ?

I try gdgCampagne.ListBoxSelectionMode = SelectionMode.None but it doesn''t work.

Try setting

grid.AlphaBlendSelectionColor = Color.FromArgb(0, grid.AlphaBlendSelectionColor);

This code makes the alpha value of the selection color to be zero, and should make the ''selected'' line invisible.

The problem is i want to use alphaBlend for column but not the line.

If i set AlphaBlendSelectionColor to 0 i dont show the selected columns... but it''s fine for my line.

Is it possible to define alphablend for a particular selection ?

If is not possible may be the solution is to manage the selected line with the currency manager ?

You can turn off the alphablend and use PrepareViewStyleInfo to color a selected column.

this.gridDataBoundGrid1.AlphaBlendSelectionColor = System.Drawing.Color.FromArgb(0, 178, 180, 191);

private void gridDataBoundGrid1_PrepareViewStyleInfo(object sender, GridPrepareViewStyleInfoEventArgs e)
{
	if(e.ColIndex > 0 && e.RowIndex > 0 
		&& this.gridDataBoundGrid1.Selections.GetSelectedRows(true, true).AnyRangeContains(GridRangeInfo.Cell(e.RowIndex, e.ColIndex))) 
	{
		e.Style.BackColor = Color.DodgerBlue;
	}
}

This code works but it color my current line and not the column.

Ok it works with GetSelectedCols

this.gridDataBoundGrid1.Selections.GetSelectedCols(true, true).AnyRangeContains(GridRangeInfo.Cell(e.RowIndex, e.ColIndex)))
{
e.Style.BackColor = Color.DodgerBlue;
}
}

But the column is selected if i click on a cell on the grid and i want the column select just when i click on the header of the column.

I try to resolve this problem, thanks for response.
