Prevent unhiding of columns

[Michael Prince]

I have a grid that I provide QueryCellInfo, QueryColCount and QueryRowCount event handlers to populate with. I also programmitically configure columns at runtime like so:

gridControl1.ColStyles[1].ReadOnly = true;
gridControl1.Cols.Hidden[1] = true;
gridControl1.ColStyles[2].ReadOnly = true;
gridControl1.Cols.Hidden[2] = true;
gridControl1.ColStyles[3].ReadOnly = true;
gridControl1.ColWidths[3] = 100;
gridControl1[0,3].Text = "Instrument";

I need to ensure that columns that I specify as being hidden, stay hidden. I don''t want to allow the user to unhide columns (or hide them for that matter).

Thank you,
Mike

I solved my problem by setting the grid''s AllowSelectoin value = Cell only.

This did not solve my problem. I still need to be able to prevent the "unhiding" of columns.

Thanks

If you do not want your suer to double click and un hide a column, then try handling ResizingColumns.

private void gridControl1_ResizingColumns(object sender, GridResizingColumnsEventArgs e)
{
	if(e.Reason == GridResizeCellsReason.DoubleClick || e.Reason == GridResizeCellsReason.ResetHide)
		e.Cancel = true;
}

Thanks Clay, that did the trick.
