Since it’s a Bound Field, the Text Box is going to be Control[0].

Once we have a reference to the Text Box, we set the new first name.

At that point we need to get the new values so we can update the record, which is done slightly differently for the Bound Field and the Template Field.

For the Bound Field, we don’t know the ID of the Text Box since it’s autogenerated by the Bound Field, so we obtain a reference to it by getting the first control in the appropriate cell in the edited row.

We’re using Linq to SQL to pull data from our database and bind it to the Grid View.

We’ll revisit this method when we implement the sorting functionality.

First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.We also want it to be something persistent, so that, for example, if you sort, then page, the sort is maintained.The way we’ll accomplish this is to create two properties that store those values in View State.In both cases, the controls are added to the controls collection for the cell.You can see that in the case of a Template Field, the exact spacing within the control becomes significant, so it’s generally better to get a reference to the control by ID using Find Control than to use the Controls collection.For the Template Field, we do know the ID of the control since we specified it in the markup, so we obtain a reference to it by calling Find Control on the appropriate row of the Grid View.The Grid View Row is the naming container for the Text Box in this case, so we need to call Find Control on the appropriate row, but we do not need to call it on the specific cell.If we were using a Template Field instead, the compiler translates the markup in the templates to the appropriate types of controls in the same way as the page markup in parsed.For this example, the Item Template would be transformed into a Literal control, and the Edit Item Template would be transformed into a Literal control, a Text Box, and a Literal control (the literal controls would include the spacing between the Edit Item Template tags and the Text Box tags).After specifying the query, we add the appropriate sorting. When you bind a Grid View through a Data Source ID, the Grid View will update this value since it is internally tracking the sort expression, so it knows when to switch between ascending and descending.We can implement it in this way without a performance impact because the data is not actually retrieved from the database until required, so we can build up a chain of queries up to that point and only the end result will be pulled from the database. When manually databinding the Grid View, this will always show ascending, so we need to handle this manually with the following logic: After that we save the new Sort Expression.
