Extracting edited items across multiple pages in a radgrid

[saravanan k]

Hi,

           i have a radgrid with allowpaging = true and allowmultiplerowedit = true. I have a checkbox column in the grid. When i load the grid in edit mode the values of the checkboxes will be changed by the user. User can check or uncheck multiple checkboxes across pages at one go. But when i try to retrieve the edited values in server side using the below snippet i am getting only the edited values of current page.

foreach (GridEditableItem editedItem in grid.EditItems)
                    {
                        Hashtable newValues = new Hashtable();
                        //The GridTableView will fill the values from all editable columns in the hash
                        grid.MasterTableView.ExtractValuesFromItem(newValues, editedItem);

                        if (true == (bool)newValues["myCheckBoxColumn"])
                        {
                            // processing logic
                        }
                    }

Please help me with a sample code snippet, so that i can get the edited values in other pages as well.

Thanks,

Hello Saravanan,

To access all items in all pages into the radGrid you could try following approach:
Disable the grid paging, temporarily, retrieve all the rows and then enable paging back again. This approach could be achieved by setting the AllowPaging property of the grid to false at a certain stage of the lifecycle and rebind the control invoking its Rebind() method, then traverse all items in it.

C#:

grid.AllowPaging = false;// disabling paging
grid.Rebind();
foreach (GridEditableItem editedItem in grid.EditItems)
   {
     .  .  .  .
   }
grid.AllowPaging = true;// re-enable paging
grid.Rebind();

Also you can refer the following documentation which explains how to persist the selected rows server-side on sorting/paging/filtering/grouping. Use the same logic and make necessary modification.

Hi Princy,

              Thanks for the reply. Your first suggestion was good. I have applied it.

But the second one doesnt suit my requirement. My grid is loaded in edit mode and remains in edit mode till the end. There is no select and deselect concept to a row. When i change values in few rows and navigate to next page and come back to the previous page the changes i made are not persisted. 

Kindly help me to tackle this scenario.
