Contol)Text; it werk just Fine any comment and thx for the code Instead of adding a Customer ID to your table and later pulling the text to get the ID number, a more reliable way to do it is to add a Data Key Names field to the grid example in the page: You can then access this information at any time with the following in code: Grid View1. Row Index]["id"]); You can do this with any field, but I've found customers get confused when they see the ID field and kept asking me why it was there, this also eliminates any issues if you change the display order of your table later (maybe add an edit/update/cancel control) Hey...great article ;)But I got a problem... So here I go with my example:protected void Grid View1_Row Updating(object sender, Grid View Update Event Args e) and the debugger says: Exception Details: System.
Nor does it represent the opinion of my dog, because I don’t have one. I have a project that I coppied the above code into. Data Keys[Row Index]["Customer ID"]in the Update event it would be something like:int Customer ID = Convert. Format Exception: Input string was not in a correct format.
Information regarding the origin and location of the exception can be identified using the exception stack trace below.[Http Exception (0x80004005): The Grid View 'Grid View1' fired event Row Editing which wasn't handled.] System.
On Row Editing(Grid View Edit Event Args e) 236 System.
The above piece of code will also do the same as label in Item Template and Textbox in the Edit Item Template.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.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.Font-Names="Verdana" Font-Size="10" Data Key Names="Product ID" Auto Generate Columns="false" onrowcancelingedit="Grid View1_Row Canceling Edit" onrowediting="Grid View1_Row Editing" onrowupdating="Grid View1_Row Updating"In the above code, I set two properties Show Edit Button and Show Cancel Button of Command Field.
