Rowupdating cell value
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.
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.
We’ll start with binding data to the Grid View, then build up functionality from there.
First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.
We’ll get to how these properties are populated shortly, but first we need to go back to the Bind Data method.
The original method shown above did not implement any sorting, but now that we have a place to store the Sort Expression and Sort Direction we need to change that.
