NET Grid View markup and associated code lets first enumerate the important code pieces of this tutorial.In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.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.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.Save all or press "Ctrl S" and hit "F5" to run the page, the page will look as in the following image: Click on "Edit the Grid View", it will display Textboxes in each cell as in the following image: Edit the value(s) here and click on the Update link, it will update all the data or to remove it click on the "Delete" link above the image shown.One note will be helpful for you, while describing Columns in Grid View if you are using a boundfield then create objects of the control using cells[index] in the rowupdateing event of Grid View, but if you are using controls itself like Label or textboxes etc then use Fincontrol("stringid").
In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.Last but not least you will need the 12.2.5 version of Dev Express ASP. If you do have a more recent version, upgrading the project should be easy.Check this post about how to get the Dev Express controls and on how to eventually upgrade the project I will not go in the detail about the environment and developing requirements, if interested jump op to my other posts.The attached project is written in Visual Studio 2012. Also you will need a Microsoft SQL Server 2012, Express or and more advanced version will be just fine.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.
