Rowupdating index was out of range
We’ll revisit this method when we implement the sorting functionality.
NET forums is how to deal with exceptions like The Grid View 'Grid View1' fired event Row Editing which wasn't handled.First, we’ll implement a method to databind the Grid View, which will be called whenever databinding needs to be performed.We’re using Linq to SQL to pull data from our database and bind it to the Grid View.The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.The Grid View 'Grid View1' fired event Sorting which wasn't handled.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.
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.
The required actions for paging to work are setting the new page index, setting the Data Source, and calling Data Bind (the last two through the Bind Data method).
In addition to that, we’re resetting the Edit Index and Selected Index when the page is changed to avoid cases, for example, where you change pages and are suddenly editing a different item.
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.
The Grid View does know the events that should be used to implement them, so the exceptions shown above are thrown when you try to perform one of these operations, but you have implemented the appropriate event handler.
Once we have a reference to the Text Box, we set the new first name.
