A datakey represents the primary key field or field of a record that can uniquely identify it in a data-bound control. Row Index represents the index of the particular row.
For this situation, many developers use invisible columns (Hidden columns) in the gridview to identify that row.
We can achieve the same functionality using Datakeys.
i modified the code but the _row Updatingfunction is not getting the new values but are still looking at the oldvalues.
i was surprised that the person who posted the question abovedoes not face the same problem.i had used the data Control Field Cell and i had also used the e.
If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method.
Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method.

If we move our mouse on to the variables, which hold the cell values, we can see the old value instead of new updated value (Refer the debugging Screen Shot at the Top).
Please help me with writing a Row Updating function in C#, I don't know how to grab the current field's value and also get the old value for one of keys (which is Project Name for editing) of the selected row. the idea wa to don't allow binding the grid view after a post back.
hello my problem was that my gridview editable controls heep their old values. this is due to the grid view binding in the page_load method after every post back.
I have the exact same problem (using VBinstead of C#) where my return shows old data; not new: *You might justbe saving my life, as i'm about to jump out the window*Dim cell As Data Control Field Cellcell = Race_GV.
