Detailsview itemupdating e newvalues empty
Non of my fields are Template fields and they are all databound. Details View Mode Event Args ) Handles Details View1. I had created all of the databindings and everything was working very well. All I want to do is intercept the New Values and put them in my custom data solution. Details View Update Event Ar gs) Handles Details View1. My custom data routine that I was using to bind data to my Details View was comming from the active directory. This is driving me batty as I cannotdo anything with my data.In brief, LINQ to SQL compares the original value and new value and generates SQL code to update the original object.Since the original object was modified by the Form View, it will never be found by SQL and no update will occur!The Object Data Source has two methods, select and update, that are stored procedures defined in a Table Adapter.The Select stored procedure takes 1 parameter--the record id--and returns the fields populated in the Details View. I think I might have a fundamental misunderstanding of how this all works!Hi Everyone, I am having a massive issue trying to get custom data into my DV. I created a Item Updating mode to handle the item update. I create a USER and EMAILUSER class and populated them with their corresponding attributes. Non of my fields are Template fields and they are all databound. Details View Mode Event Args ) Handles Details View1.
Many thanks Mike Mike, try something like this in your Item update handler: Protected Sub dv Customer_Item Updating(By Val sender As Object, By Val e As System.
While there are other techniques you can use with Linq to SQL to avoid the issue above, the point of this post is to show how the Form View handles null values.
The workaround is to subscribe to the Form View Item Updating event and look for string.empty New Values and set those to null instead.
Here we have a Text Box inside an Update Panel inside the Edit Item Template.
Since two way binding is not supported for the First Name Text Box, the special code for extracting values is not generated resulting in null being sent back for the First Name property. I just don't understand why using a nested control doesn't work properly.
I think I might have a fundamental misunderstanding of how this all works! Copy To(records, 0) Dim data Entry As Dictionary Entry For Each data Entry In records If Is DBNull(data Entry. I am using a Details View which is populated dynaically at runtime: table = Data Table from Dataset passed back from Data Access Layer DV1 = Details View foreach (Data Column col in table. New Values collection to pass back to the DAL to update the table.
