Gridview rowupdating get datakey

Most of the data controls have events ending in ing and ed e.g. In most of the event handlers of the ing events it is easy to get the values from the event args.Forgive me for the variation in my code formatting I'm trying to find the right one.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.These properties will automatically render Edit, Update and Cancel buttons inside Grid View column.The last parameter is a boolean value which tells the method whether to execute an Insert (false) or Update (true). In-order to perform Edit and Update in Grid View we need to use three events ( Grid View_Row Editing, Grid View_Row Canceling Edit , Grid View_Row Updating). For those who do not know on how to generate Events in Grid View you can follow these steps below: I have a project that I coppied the above code into. A friend asked me to help him out on this and frankly it has me completely stumped as well.

After you've created a layout with a data control of your choice and eventually bound them to some datasource, you almost always want to get that data back out of them(and why wouldn't you, its your data).One thing you'll learn about developing webpages is that its like petting a porcupine (yikes).If you go with the flow, you probably won't get stuck, but the moment you try to go against the grain you end up with a hand full of thorns.Free counters Added on January 19,2012 Follow Me @vmsdurano A bit About Me Disclaimer The opinions expressed herein are my own personal opinions and does not represent the opinions of my employers. Contol[0])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. 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.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.If we look at this event we can see the Grid View nicely packages for us the new values, old values and the keys for the updating row.Unfortunately these dictionaries are only filled out if you are bound to a datasource control :(.
