Rowupdating event example
Since it’s a Bound Field, the Text Box is going to be Control.Once we have a reference to the Text Box, we set the new first name.We’ll get to how these properties are populated shortly, but first we need to go back to the Bind Data method.
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.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.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.
