In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.In this tutorial I will show you how you can create an editable Grid View control for administrators to modify database records directly into the Grid View control. Edit Index = -1; Bind Data(); } catch (Exception ex) { throw ex; }}Please keep in mind that there are many different ways to update the database using the Grid View control depending on the type of data you are updating and the functionality the user need and there are many solutions to achieve the same end result.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. In the above tutorial I tried to give you one of the easiest solutions and I hope you can go explore Grid View control editing further after learning the basics from this tutorial. Thanks There's a very good suite by Shield UI that I have a fantastic experience with and it is a very good solution for everything related to ASP.net, including grid, chart, etc..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. Normally in gridivew, All buttons are enabled (Edit, Update or Cancel)Is it possible to force the user to Click on Update/Cancel button, when in Record Edit Mode. In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field. These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.

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. Now I will show you the C# code behind file of the above ASP. NET page that will handle different Grid View events to provide complete editing functionality. Data Bind();} For brevity I am not storing connection string in the web.config and also not using any Data Access Component. In the Page_Load event, you simply load your data from the database and bind it with the Grid View control as shown below: protected void Page_Load(object sender, Event Args e){ if (! Is Post Back) { Bind Data(); }} private void Bind Data(){ string constr = @"Server=COMPAQ\SQLEXPRESS; Database=Test DB; uid=waqas; pwd=sql;"; string query = "SELECT Product ID, Product Name, Unit Price FROM Products"; Sql Data Adapter da = new Sql Data Adapter(query, constr); Data Table table = new Data Table(); da. Next event is the Grid View Row Editing event to give ASP. You need to set the Edit Index property of the Grid View with the New Edit Index property of the Grid View Edit Event Args class. If user clicks the Cancel button while Grid View is in editing mode, you need to Cancel the Editing process and also need to reset the Edit Index property to -1 in the Row Canceling Edit event of the Grid View control as shown below: The last step is to handle the Row Updating event to actually update the back end database.
