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).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.NET 2.0 most of the examples and tutorials deal with setting the Data Source ID, which buys you a lot of automation that you may not even appreciate unless you’ve done this the old fashioned way.In this example, we’ll go through a fully featured Grid View with editing, deleting, selecting, sorting, and paging functionality that is manually bound and identify the limitations and some of the workarounds. Sql Data Source, Object Data Source, Linq Data Source, etc) specified in a Data Source ID, the Grid View can automate many functions because, through the data source control, the Grid View on its own can perform the following operations: When you manually bind data to a Grid View, the Grid View itself cannot perform these operations, so they must be implemented in your code.
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.
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.
The Grid View 'Grid View1' fired event Sorting which wasn't handled.
The Grid View 'Grid View1' fired event Row Deleting which wasn't handled. When I say manually databinding I mean not using a data source control specified as a Data Source ID, but rather setting the Grid View’s Data Source equal to the appropriate data object and calling Data Bind. NET 2.0 are familiar with how to deal with this, but since ASP.
We’re sorting on the appropriate field based on the Sort Expression, and setting the direction based on Sort Direction by calling either the Order By or Order By Descending methods. As with paging, we also reset the Edit Index and Selected Index when sorting.
