Hi susmitha,

Not sure but maybe some cells contain strings that are too long, after removing them the problem has been fixed for me.

Hi: I am getting the same error. I have a DataTable with 175,000 records, with one of the fields being OCR text. I am using an OrderInfoCollection as the DataSource for the sfDataGrid control.

The sfDataGrid control was loading and populating just fine before I started adding text to the OCR field. Many of the OCR text fields have a length of over 40,000 characters at this time (will be reducing the length of characters in this field soon).

So... I am very interested in what is causing this error, and the way to solve it. Please keep me informed on this error.

Thanks!

Hi Kim, 

Thanks for the update.  

We are able to reproduce the reported issue when the length of any value of a cell has 40,000 characters. On analysis we found that the issue occurs from the Graphics.DrawString method which we have used to draw the cell values. This can be reproduced in a simple windows application as given below.

We have raised a query regarding this in developers community.

We will update with further details once we get any prompt solution for this query. We appreciate your patience.
