Gridview rowupdating get cell value
So what you need to do is store the data source (maybe in Session) and only bind rebind the data when you absolutely need to (Like during the Is Not Post Back) Do you understand? 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).This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
As a beginner it's very tough and challenging to work with controls like a Grid View in ASP. Even I faced difficulties at the starting point of my career. Here, I am not going to explain about Grid View and other events in it, because there are a lot of good articles about that.
I have the following code below in my Grid View1_Row Updating event. Maybe after midnight today, or sometime this weekend. When I go to configure the datasource for my Object Data Source, on my first screen where I designate the business object, my dropdownlist is blank. Turns out getting the DAL, BLL, and the Object Data Souce in place, did the trick. Tracing the code, using both methods above, the value of the textbox is not being passed back; it doesn't appear in the newvalues either.
That probably needs to be linked into the Object Data Source along my Get Products, as well as the Add Products, and Delete Product methods. Problem is, I don't have the time at the moment yet. And back to my original question, how to I get the new value? I have a gridview, go into edit mode, enter a value in a textbox, then click update.
I do have a Update Products method in my business logic class which is ties into the data class. Once I got that in place, the dropdownlist populated. I haven't had many problems with gridview, but this one has thrown me. Enabled = allow Admin Edit End If Dim price As Text Box = CType(e. Read Only = Not allow Admin Edit End If //some more columns enabled/disabled too End If 0 Then Return If e.
On the Gridview Row Updating event, I try to retrieve the value, but I'm getting the value 15. Because I just bound only the Get Products method resultset to the Grid View, it doesn't have the mechanism to handle Updates. But I tried to recreate everything at home, but I missed methods in my DAL class. Find Control("list Box Product"), List Box) If Not ddl Is Nothing Then ddl. Controls(0), Text Box) If Not price Is Nothing Then price. I must be missing something here, but I can't figure out what it is. Hi, I've have this problem before, the only solution i've found is to use only one templatefield with divs with fix width to simulate columns, and use only one Edit Item Template. In there, I enable and disable fields based on access levels etc...
