In this installment we built upon the demo created in the Customizing the Editing Interface article and saw how to handle ASP.
This article explains how to perform insert, update and delete operations in ASP. Let us take an example to perform CRUD operations using Entity Framework Database First approach.
Editing the Grid View control can be an incredibly easy feature to add for certain database tables, especially those who have no foreign key associated and can easily be edited through the use of a standard Text Box web control as shown in the figure below: 1.
You need to include the Grid View Command Field column to add Edit, Update and Cancel Buttons in the Grid View. You need to include Template Field for every column you want to provide Editing because Template Field provides you both Item Template and Edit Item Template to create interface for two separate Grid View modes. You need to handle Grid View events such as Row Editing, Row Canceling Edit and Row Updating to provide desired editing functionality.
Now I will show you the C# code behind file of the above ASP.
Apologies in advance I am totally new to Sencha Architect and have been using it less than 48 hours.
Is there a simple way to continually update a store from a in real-time.
Basically I have a JSON object returned from my PHP back-end querying a db to get values which I display in a grid view which works fine.
SELECT [Product ID], [Product Name], [Products].[Category ID], [Category Name], [Unit Price], [Discontinued] FROM [Products] INNER JOIN [Categories] ON [Products].[Category ID] = [Categories].[Category ID] ORDER BY [Product Name] SELECT [Product ID], [Product Name], [Products].[Category ID], [Category Name], [Unit Price], [Discontinued] FROM [Products] LEFT JOIN [Categories] ON [Products].[Category ID] = [Categories].[Category ID] ORDER BY [Product Name] value is translated into an empty string and the corresponding drop-down list item is selected.
Likewise, if at save the selected drop-down item is the empty string item then it is translated into a database This article was the third installment in this series that examined editing data with the data source controls in ASP. The Updating Basics installment examined the core concepts of editing, while Customizing the Editing Interface explored how to enhance the Grid View's editing experience.
I am using Template Field’s Item Template and Edit Item Template for providing read only and editing interface of the same column in the Grid View.
By Default, Grid View control displays Item Template which directly shows the Product Name and Unit Price columns but when user clicks Edit button Grid View automatically switches to Edit Item Template and display the control available inside Edit Item Template for user editing.
While the Customizing the Editing Interface article provided a complete, working example of creating a customized editing interface, it had one potentially criticial shortcoming - the approach did not work with products that had a This article builds on top of the demo presented in the Customizing the Editing Interface article, so please be sure that you have read, implemented, and understand the demo from the previous installment before continuing on here.
