There are a few other options available besides trying to create a List<UltraGridRow> collection, all of which are likely to be much easier to implement:

• Use the underlying data source, rather than the grid's rows.  This will only work if you haven't sorted or filtered the grid, or if you haven't hidden any rows.  You mention that you're sorting, so this likely isn't an option in your scenario - I mention it for the benefit of others who are trying to do something similar.  For those where this is an option, it's likely the easiest option to implement.
• Use the Rows collection itself, without trying to convert it to a List<UltraGridRow>.  This is an object of type Infragistics.Win.UltraWinGrid.RowsColletion.  It's already a strongly-typed collection, so you should be able to achieve most of the same results as you could with a List<UltraGridRow> object.  This is likely the easiest option to implement in your scenario.
• Use the result of calling the grid's Rows.GetFilteredInNonGroupByRows() method.  This returns you an array of UltraGridRow objects, which represents all the rows that meet any filter criteria applied.  This is the best option to use if you're using filtering.
• Rather than creating a List<UltraGridRow> collection, you can instead create a List<> of your underlying data source.  You can iterate through the grid's Rows collection and add each row's ListObject to your list.  This will get you a list of the underlying data object for each row in the grid, which will be sorted in the same order as your grid.  If you're using filtering or if you're hiding rows, ou'll need to check each row's HiddenResolved property to determine whether to exclude it from your list.  I believe this is the best overall solution, since it comes back to using your underlying data source yet takes advantage of the sorting, filtering, and hiding capabiliities of the grid.

By the way, is there a reason why you're not using the grid's built-in printing functionality?  I assume that there is, if you need to generate an HTML output.  I ask just in case it's something you hadn't considered, since nearly all of the work of putting the output to the printer (or print preview) is already done for you.

Hi,

Thanks for your reply.

i will explain my question in a detailed manner.

For showing the data we are using the wingrid. As you very well that, we can do anything in the wingrid.

Things we are doing in the wingrid

 - Changing the position of the columns
 - Sorting any columns by ascending or descending

We are getting the data through a list. by means of list we are showing the data in the wingrid.

In that wingrid we have the print option.This will print the data in the HTML format.

For printing we are using the same list to print the data.

Problem

Initially when u give the print screen, it will print the data whatever in the list. but when u change the position of the columns or sort any of the columns, the list is not getting updated, since we set the property for the ascending and descending and for changing the position of the columns, we are using the aftercolposchanged event to do that work.

Solution :( what i am trying to do)

while clicking the print button, i am trying to take all the rows as well as the column headers from the wingrid and store it in a List. since we are using the list to show the value in HTML format.

so i required all the rows and column header in a list. so i can make a loop to get the value.

i am unable to convert the wingrid row to the new list.

Help me how to do that... need a sample to proceed.

If u want more information, let me know.
