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.I would need to set values passed to the Sql Data Source control on the update event, and as part of this I would need to reference the controls contained in the row being updated.
The Grid View is bound to a strongly-typed collection, derived from Collection Base, through the control's datasource property at runtime. The Grid View is bound to a strongly-typed collection, derived from Collection Base, through the | control's datasource property at runtime. I don't recall seeing it emphasized in the documentation, and these kinds of dependencies create annoying bugs.
From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources lets those dictionaries be populated. | | From some googling it appears that, at least in the release candidate for NET2 this was a known bug; only binding to Data Sources | lets those dictionaries be populated. 2) I think it's weird that the "value" capability is tied to the parameters collection. That way it'd work with both types of data binding.
Please post the code for your Page_Load method and the that handles your Update (your C# code) so we can have a better look at what's going on. Please give some references and/or details of how to. This wipes out the data provided by the user during editing (editing happens after the page load).
If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method.
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.
