looked at Reset Bindings(), but it has not produced the correct result. Reset Bindings(false) and re-assigning the datsource caused flickering with potentiail overhead if only one item change frequently. Documentation for End Edit seems to indicate that it would do nothing if the objects contained by the datasource do not implement ' IEditable Object'.
Reset Bindings(false); You will have to manually call Reset Bindings() after the data source changes if you use a container that cannot do that on your behalf.
Introduction Step 1: Creating a Form View that Supports Deletion Step 2: Calling the confirm(string) Function from the Client-Side onclick Event of a Delete Button Step 3: Configuring the On Client Click Property for the Delete Button in a Command Field Using Template Fields Conclusion Over the past several tutorials, we've seen how to use our application architecture, Object Data Source, and the data Web controls in concert to provide inserting, editing, and deleting capabilities.
The deleting interfaces we've examined thus far have been composed of a Delete button that, when clicked, causes a postback and invokes the Object Data Source's Delete() method.
Calling Data Bind (even multiple times) doesn’t really have an impact on performance, because all it does internally is play with Boolean flags.
During rendering, these flags are checked to determine whether the programmer has explicitly ordered data binding.
A design surface and hundreds of controls and components let you rapidly build sophisticated, powerful UI-driven sites with data access.
Reseting an individual item using Reset Item() worked!
From looking over the documentation, the example seems to indicate that Reset Bindings() should be called if I update the underlying collection, instead of the Binding Source directly. I tried the built in mechanism using Property Changed but nothing updated.
Raise your hand if you’ve written a web application that couldn’t be cataloged as a data-driven application. To data-bind all the controls in a page, you need code like that in Listing 2 (below).
I’m betting that you didn’t raise your hand, because the definition of a data-driven application is quite blurred and flexible enough to incorporate nearly everything. NET controls, behaviors are attached to the control’s life cycle through the Data Binding event handler. It’s the page—if you properly instruct it to do so. Calling the Data Bind method has the effect of triggering the Data Binding event for all the controls in scope.
