Select the Delete Query property, which will bring up a set of ellipses.Figure 2: Select the Delete Query Property from the Properties Window provide a value for this parameter (leave its Parameter source at None ).Note Since we ve already discussed the inserting, editing, and deleting capabilities of the Grid View, Details View, and Form View controls, this tutorial will focus on configuring the Sql Data Source control to support these operations.If you need to brush up on implementing these features within the Grid View, Details View, and Form View, return to the Editing, Inserting, and Deleting Data tutorials, starting with An Overview of Inserting, Updating, and Deleting.Place your perform File Upload() somewhere else on in inserting or updating event . I put a break point in the Item Command and in the Proform Upload method and somehow it bi-passes everything and just gave me the error. In previous tutorials we learned how the Object Data Source control allowed for inserting, updating, and deleting of data.For now, let s use the Properties window in the Designer, although the Configure Data Source wizard or declarative syntax option would work just as well.

I use the Form View_Item Updating and Form View_Item Inserting method to perform my file upload if there is any.However, the problem is, if it fails, what do I do to stop the inserting/updating process to occur? The Lable (lbl File Name) is bind to the database field "file Name" but somehow during the update, everything gets updated except the file Name field. In the sql Data Source_updating method, does it executes all the code inside of this method before it actually updates or does it updates first and then executes all the codes? You can, however, cancel the database operation by setting the Cancel property of the Sql Data Source Command Event Args to true.); will call form View1_Item Inserting again ...........thats wrong . Okay, the strange thing is none of my break works when running in debug mode. These data modification capabilities can be plugged directly into a data source control without a line of code needing to be written.An Overview of Inserting, Updating, and Deleting examined using the Object Data Source to facilitate inserting, updating, and deleting with the Grid View, Details View, and Form View controls.
