copying GridStyleInfo

[Andy Ullman]

Hi,

I have several small GridControls with just a few rows each. They contain lots of formatting, comboboxes, checkboxes etc. At runtime, I need to create a large GridControl using the small ones as a source i.e. by repeatedly copying the cells from the small grids to the large. The large grid may end up with thousands of rows.

I tried using GridStyleInfo.CopyFrom(), but it was slow, and didn''t seem to handle some of the cells (checkboxes, combos''s etc.) properly. I also tried instantiating new GridStyleInfo''s using the source GridStyleInfo as an argument to the constructor. That was much faster, but I must be doing something wrong, because the new cells seem "connected" to the old (ie if I enter a value in the cell, it affects the cell I used as a source). Do you think this is the best approach to the problem - if so, what am I doing wrong?

Thanks,
Andy

You might try using these two methods to copy data from one grid and then move it into another.

this.gridControl1.DataExchange.CopyCellsToDataObject
this.gridControl1.DataExchange.PasteCellsFromDataObject

Here is a little snippet that moves 1 grid to another. You would have to set the paste row/col to move to the proper location.

private void button1_Click(object sender, System.EventArgs e)
{
	GridData data = new GridData();
	int rowCount, colCount;
	GridRangeInfo range = GridRangeInfo.Table();
	range = range.ExpandRange(1, 1, this.gridControl1.RowCount, this.gridControl1.ColCount);
	this.gridControl1.DataExchange.CopyCellsToDataObject(out data, range, false, GridDragDropFlags.Styles, out rowCount, out colCount);
	this.gridControl2.DataExchange.PasteCellsFromDataObject(data, GridRangeInfo.Cell(1,1), true, GridDragDropFlags.Styles);
}
