PopulateValues - to expand the grid automatocally

[Charles Vereker]

I''ve written the following method:

protected void PasteData(GridRangeInfo rangeInfo, object data)
{
// expand the grid if necessary (to fit the data!)
if (rangeInfo.Bottom > this.RowCount)
this.Rows.InsertRange(this.RowCount+1, rangeInfo.Bottom - this.RowCount);
if (rangeInfo.Right> this.ColCount)
this.Cols.InsertRange(this.ColCount+1, rangeInfo.Right - this.ColCount);

this.Model.PopulateValues(rangeInfo, data);
}

When I had a UserControl with a GridControl as a member then this worked. Now that my UserControl inherits directly from GridControl an exception is generated (Index out of Range) in the PopulateValues call.

Can you post a call stack showing the exception?

You might check whether this.RowCount/ColCount and base.RowCount/ColCount are different values?

One comment is that in a GridControl, it should automatically add rows/columns during a paste if they are needed (unless you have set the grid.Model.CutPaste.ClipboardFlags to include the GridDragDropFlags.NoAppendRows and GridDragDropFlags.NoAppendCols flags).

"An unhandled exception of type ''System.ArgumentOutOfRangeException'' occurred in syncfusion.grid.windows.dll

Additional information: Specified argument was out of the range of valid values."

They are different (i.e. pre-InsertRange) values. I tried setting them explictly but that did not work.

The name of my method is misleading. It should really be an override of PopulateValues. The data passed in is not the result of a cut and paste operation, but rather an array, or DataTable from elsewhere in my program.

Something else to try. Instead of calling

this.Rows.InsertRange
this.Cols.InsertRange

try calling

this.Model.Rows.InsertRange
this.Model.Cols.InsertRange

If you can upload a sample showing the problem (or email one to [e-mail] mentionaing this thread in the subject line) we can try to debug it here.

I still get an exception.

I will email/ upload my code later this week.

Thanks for the exceptionally quick reply!!

In cleaning my code of other dependencies before uploading I took on board another suggestion/instruction of yours to do some things AFTER the GridControl had been added to it''s parent''s control.

This fixed the problem (& others!!)

Thank,
