Formview fired event itemupdating which wasn
The Grid View 'Grid View1' fired event Page Index Changing which wasn't handled.
Do I have to call the Change Mode() method in the Mode Changing event handler? I can see the mode in the process of changing, because my Mode Changing handler gets called, but then the Mode Changed handler never gets called.
- Mark Hi Mark, I had a look at the Form View control's code, and it seems Mode Changed event is only raised when formview is bound to a datasource control (i.e. See it for yourself: private void Handle New() Unfortunatelly, you have to handle Mode Changing event and call Change Mode() manually with e.
I'm trying to understand how to respond to mode changing events in a Form View control.
I'm not using datasource controls, so I have to do more of the plumbing myself.
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.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.When you manually bind the Grid View, this tracking does not occur, so we must implement some mechanism for tracking those values.We also want it to be something persistent, so that, for example, if you sort, then page, the sort is maintained.Finally we need to populate the Sort Expression and Sort Direction when they change, and we’ll handle that in the Sorting event. Also like paging, so show that it does get called, databinding is handled in the Sorted Event ( First, we obtain the User ID of the affected row from the Grid View Data Keys collection, which we use to pull the appropriate record from the database.Tags: Adult Dating, affair dating, sex dating
