Notes: I stayed away from stored procedures for simplicity. Dates are handled as strings - handing them correctly is another blog 🙂In my actual app I am using auth - I cut that for simplicity of this blog entry I removed all state managment: user deleting of a row Ok step one is a database - you need to have one 🙂 I used an auto incrementing ID field set as a prmary key - this is used for master\details syncing and image gathering (explored later in this blog). Things of imortance are the ID column (primary auto incrementing field) and the image column (type is Image).
I think this is because the Item Updating event fires before the List View updates the record.
I've got a simple List View, with the typical Edit/Update/Cancel buttons.
You can use it to display, edit, delete, select, sort and page your data just like Grid View.
However unlike Grid View control it is totally template driven which means developers need to use its different templates to control the rendered output markup just as they do in Repeater control.
NET 3.5, Microsoft introduced two new databound controls: the List View and Data Pager control which you can use to display and paginate your data in extremely flexible way.
In this tutorial I will show you how you can use List View control to display data from the database.
Data entered in textboxes is not getting updated in database.
In debug mode I see that textbox1 and textbox2 in Item Updating event contain the same values as they had before calling Item Updating.
If you run the application you will have a dropdownlist populated with our vendors Now we add a second objectdatasource with the same Type Name, and we set the Select Method, Update Method, Delete Method and Insert Method to use the methods of the Vendors Managerâ€™s methods. Itâ€™s because we donâ€™t cause a postback to the server to let him change the data.
To achieve that, we simply set the Auto Post Back property of the dropdownlist to true, so the dropdownlist is Re-run the application and change the selected value of the dropdownlist.
There is one drawback though: you need to know exactly how control works with other controls such as the Data-Source controls and despite the fact that Visual Studio allows to configure the control via the Design mode from the Smart Tag, the most times you will need to change the generated code in order to function properly.
