Detailsview fired event itemupdating which wasn art of dating c00l
One piece of additional information: certain bind fields in the formview's edit template are optionally set to invisible during the course of editing.
I am not sure if invisible bind fields will lead to "ODS's do not match ODS Update Method's parameter"?
- 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.
New Mode argument: protected void fv_Mode Changing(object sender, Form View Mode Event Args e) Done.
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. I didn't think to check whether Mode Changed was only called when using a Data Source ID-object.
I don't generally use Data Source ID-type objects, preferring a more "explicit" style of data binding.
- Mark I'm trying to understand how to respond to mode changing events in a Form View control.The last lesson presents the new Dynamic Data features of ASP.NET that allow you to easily create websites for working with the create, read, update, and delete (CRUD) operations of an entire data model that exists as either a Data Context (such as LINQ to SQL) or an Object Context (such as LINQ to Entities).NET is smart enough to do it for me automatically !! Supplement information: Upon clicking Edit Item Template's update link button: Item Command event is triggered, then return and goes no further. This is my foresaid work around solution: programmatically fill in datasource's parameters, when apparently ASP. However, I am still appreciate if anyone can explain this problem.Why isn't Form View's Item Updating event fired, when obviously link button's command name = "Update"? protected void Form View1_Item Command(object sender, Form View Command Event Args e) protected void Object Data Source1_Updating(object sender, Object Data Source Method Event Args e) protected void Object Data Source1_Inserting(object sender, Object Data Source Method Event Args e) private void set ODSParameter(Object Data Source Method Event Args e) Thanks for your suggestion, but I don't think it is a common practice to invoke ODS' update event manually.
However a link button siting right beside the image button with a command of "Update" just like the image button, did infact proceed to the ODS updating. Form view doesn't seem to support image buttons that fire commands, unless there is some magical setting I am missing.
