Gridview rowupdating event handler
Enable Callbacks property is set to "true" Post Data is applied automatically before required events. I guess it is because the Html Edit Form Created code initializes the editform controls with the old values from the gridview. If your scenario is different, please feel free to modify my sample to illustrate your approach. I have modified our project according to the information above and handled the ASPx Grid View. Please let us know whether this approach suits your needs. Load Post Data Recursive (as mentioned in your previous post) anymore which makes code much shorter and easier to understand.
This can be beneficial to other community members reading the thread.Thanks, Jenny -Why is it not possible to use the Enable Callback = false in Pop Up Edit Form mode? The cause of the problem is that grid gets its Post Data after the Page_Init event but before the Page_Load event. Data Bind method is called in the Page_Load event handler, it disturbs values returned from Post Data. We recommend binding the grid in the Page_Init event handler. - When the user opens 2 tabs for the same page, the session data is not specific for those tabs and state saved in the session variable can conflict between pages (removed on tab1 but still available on tab2). Viewstate is page-specific and only lives within lifecycle of let's still use session data as you specify, I'll try to solve that later.== I have 2 questions using your example:1) The e. The appropriate solution is storing the Data Source in the Session. Load Post Data to the required controls explicitly via the Dev Express. Please take a look at the Features - Data Binding online demo, illustrating this approach in action.
Now I would like to add event handler for dropdownlist which would react on Selected Index Changed.Yet in processing the Row Updating event, I cannot access controls in my Edit Item Template because my gridview is apparently no longer in edit mode (grid Vew. However, if I implement the gridview directly in an page (instead if in an User Control), the gridview behaves correctly in the rowupdating event hander.I saw another, rather old, post describing this same strange behavior to which no one replied: Net/microsoft.public.dotnet.framework.aspnet.webcontrols/2006-12/msg00009Here's the code behind: protected void grid View_Row Editing(object sender, Grid View Edit Event Args e) protected void grid View_Row Updating(object sender, Grid View Update Event Args e) Here is the user control markup: Auto Generate Columns="false" On Row Data Bound="grid View_Row Data Bound" On Row Canceling Edit="grid View_Row Canceling Edit" On Row Deleting="grid View_Row Deleting" On Row Updating="grid View_Row Updating" On Row Editing="grid View_Row Editing" Show Footer="true" Causes Validation="false" Edit Text="Edit Period" Show Delete Button="true" Delete Image Url="delete.png" Delete Text="Remove Period" Update Image Url="~accept.png" Update Text="Save Period" Cancel Image Url="cancel.png" Cancel Text="Cancel Edits" / Superguppie. However you can use the extended method to wrap the Row Updated event and expose it to other classes (ie My Row Updated) The extension I have a possible alternative.
