Hi Jason, Thanks a lot for the reply. We are using UltraWebGrid v7.3 compatible with Asp.Net 2.0 for our application. Our primary motive is to display data and hence we are not interested in updating/inserting/deleting data back to the DataSource. Regarding the DataSource - We build a DataTable with required data from the database and bind to the grid. Now comes the issue. After binding the dataSource to the grid, we add 546 columns to the grid and and then add desired data in each of the 546 columns for each of the record present in the grid ( not to the data table). Now once this finishes, the grid takes close to 5 minutes to load!!!!. We are manipulating the grid and not the data table because we have seen similar logic applied to VSFlexGrid in VB platform and work flawlessly. We need to change the text colour of some of the column data for certain rows based on a logic, and hence we cannot avoid looping through the rows of the grid. Now, once we make these changes (like adding more data to the extra columns/changing colour)etc., (which happens very fast), the grid is not loading.. or taking a lot of time.. please guide us to solve this problem..
