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.The visitors to a web site can typically be divided into two groups: the users and the administrators.In data driven web sites, users are normally allowed to view data and administrators are allowed to add, edit or delete data.For a while now I’m trying to figure out why my method, triggered by the Grid View.Row Updating event, doesn’t work as all samples say it should do. Please post the code for your Page_Load method and the that handles your Update (your C# code) so we can have a better look at what's going on. Please give some references and/or details of how to. This wipes out the data provided by the user during editing (editing happens after the page load). If you reset the Data Source at this stage, your values for updating will be lost. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working. Please give some references and/or details of how to. Ok what's happening is that you are binding the data source for the Grid View every time a postback occurs in the Page_Load method.
NET Framework does not support all versions of every platform. Auto Generate Edit Button Property On Row Updating Grid View.
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.
Count ----------- The most common problem for losing new data entered while updating a Grid View or Data Grid is that you are resetting the Data Source for the Grid View or Data Grid in the Page_Load method. I actually don't know how to write the Row Updating function, I just found it from the internet, and so of course it's not working.
I ran into a situation this morning where the Row Updating event of a Grid View kept insisting there were no entries in either the Old Values or New Values dictionaries. not-for-mail | Xref: TK2MSFTNGXA02gbl microsoft.public.dotnet.framework.aspnet:372150 | X-Tomcat-NG: microsoft.public.dotnet.framework.aspnet | | I ran into a situation this morning where the Row Updating event of a Grid View kept insisting there were no entries in either the | Old Values or New Values dictionaries.

Also, if convenient, would you post some detailed code snippet of your page and the code behind on this? All the parameters are actually associated to the Parameters declared in Data Source control (the select and update statement in Data Source control), also we can find some parameter name related attribute such as Old Values Parameter Format String="original_" So when we do not using Data Source control, there is no info for populating named parameters .... Also, I think it'll still require us to use Data Source Control when we need to Updating event to contains Parameters collection, however, it may become more user friendly if there're some additional functions on the Data Bound control which can help extract bound values from each row /column... ha AJ9Znc P8Ei3q L2 n GKN1K6B5U57An5w PDTl Bf TR hgoc D5IBPrxek8Ok Q6ARdran47 nw== | X-Complaints-To: ab***@| X-DMCA-Notifications: X-Abuse-and-DMCA-Info: Please be sure to forward a copy of ALL headers | X-Abuse-and-DMCA-Info: Otherwise we will be unable to process your complaint properly | X-Postfilter: 1.3.32 | Path: TK2MSFTNGXA02gbl!
