Updating data in XML using Datasets with the help of Gridview

Hi All ,

I am working on editing XML values  by populating in Gridview . Before populating i have applied search criteria and based on that condition the records are populated in gridview .

Now if i want to edit or delete the problem is that the rowindex for the gridview is different with the original data comimg from XML .

If i edit the values it is adding a new row instead of editing .

Please tell the solution.

Note: I dont have any unique element in my XML attributes .
