Is this a possibility in LINQ (I'm completely new to LINQ)?I think this is enough code to make sense of what I'm doing, but if more is needed just let me know and I can post it up as well.

To change an existing row's data, you can directly assign a row's value.However, before I display the record to the user I want to remove the timestamp of a date Time value.So I tried to do the following by creating a function that takes the column name and the data row instance. Whe I add it to the watch list it contains the value I want.it is only when I assign it to row[column Name] that the value does not persist prior to databinding to the details View.I need a method that finds a row (maybe by primary key) and updates changed rows to the row in Data Table.Hi, I have an existing set of data in SQL which I am referencing as a Data Set object.

I want to update some of the fields on one of the rows based on the info that is entered into a form.

When Update is called, the Data Adapter will attempt to execute each query (UPDATE, INSERT, DELETE) on every row of the Data Set that has been updated, inserted, and deleted.

For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.

To save data to the data source, you need to call the Data Adapter's Update method.

To change an existing row's data, you can directly assign a row's value. Delete() In this example, I'll show you how to add edit, and remove, data from the Northwind database.

Note: Keep in mind that this Update is different than a SQL UPDATE statement.
