I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.Please see my code below.Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM

I have a repeater that I have bound to a sql reader via my code behind page.
However I can't figure out how to populate the controls in my repeater in my code behind code.
At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this
<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?

I am using Asp.net 3.5 listview control. In item_updating event I am using this code...
dim country as string = Dim country As String = e.NewValues("country_name").ToString.Replace(" ", "")
It's updating record correctly. for example if I update USA to USA 1 1 then it's updating like as it. But I want it to be USA11

Updates to the edited item are not passing the new / updated values but rather the original values. And I can't for the life of me figure out why when I change the original value in an edit textbox and post the update the new value is not being passed. I get the original value. Perhaps fresh eyes can spot the problem. This should be super basic but apparently I'm missing something.
Here's the code for the Item and Edit templates. The code behind is below this.

I have a typical gridview/formview master control setup. When I try to update or insert I don't get any errors but it also doesn't work. When I try to insert data all I get are null values and when I update, none of the values are updated. The formview looks like its working, but just doesn't. The primary key is an identity and it auto-increments by one.

I wanted to know if we can pass values from Parent page (in this case from Default.aspx page) to the user control and maintain those values on subsequent "Add/Load" of user control.
So in short, if I click the "Add" button it loads my "webusercontrol" and also I am able to pass my default.aspx dropdownlist value to this dynamically loaded user control and assign it to a "Label or Textbox" which resides in my "webusercontrol", now the problem is that the value doesn't persists! What I meant is , when I click "Add" button again the "webusercontrol" gets loaded again perfectly but now all my "Label's" in webusercontrol has the new selected value from the default.aspx dropdownlist.
So say for instance I have a Dropdownlist in Default.aspx page with Values "Apple, BlackBerry, Nokia" and initial value to be passed is "Apple", I click the "Add" button, now my "Label" inside webusercontrol has the value "Apple", perfect! Next when I click "Add" button again and select a different value to be passed this time say "BlackBerry" now I have 2 webusercontrol loaded on the page, so that means I have 2 "Labels" with different ID's, but now my first Label initially had the value "Apple" because that's what I had passed and now when I passed the value "Blackberry" both the labels of my webusercontrol has the value "BlackBerry" instead of one being "Apple" and another "BlackBerry"
Is there a way to resolve this issue? may be Dictionary List?

I have a problem that can't find a way to do it, I have a gridview with this columns:
ID | AreaName | CostCenter
with the "Enable Editing" option check and what I want to do is to get the values of areaname and costcenter and assign them to a label control so I can use the values for something else, for example:
ID AreaName CostCenter
1 Multiconector 1025
2 One Conector 2065
3 Plug & Play 1445
4 Splitter 1598
5 FNI 4298
and if I hit the edit button of the row with ID 4, assign the values to the labels lblAreaName = Splitter and lblCostCenter = 1598
Before I edit them, and so on with the rows I want to edit.

I'm using a ListView control to show 3 columns of pictures and 2 rows - I'm using ImageButtons and OnClick events.
I'd like to be able to click on an image thumbnail and call up the larger file based on the thumbnail details.
But it appears I'm having trouble targeting the images.
Here's what I'm trying:
Sub ImageButton_Click(ByVal sender As Object, ByVal e As ImageClickEventArgs)
Dim myImage As ImageButton = TryCast(ProductsListView.FindControl("ImageButton1"), ImageButton)
myImage.ImageUrl = "PageContentImages/myFileName.png"
UpdatePanel1.Update()
End Sub
But I get the "Object reference not set to an instance of an object." error.

I have a listview control. In the ListView1_ItemDeleting event I want to record what was deleted.
I tried using e.Values("ipAddr") but it's value is nothing.
Since this is the ItemDeleting event and not the ItemDeleted event, shouldn't I still have access to the field values? Is there a way to do this?

I would like to store some business flags (like: isFavorite, isOnLive etc.) per an html table row that won't be visible to user.
In practice, I have a simple ADO.Net DataTable on my code-behind which is used as a data-source for a asp.Net GridView control.
This table contains some business flags on its 0th, 1st, 2nd columns.
I need to store those columns on the rendered HTML of the grid-view -so that I can reach them via JavaScript- but I do not want them to be visible.

Prior to using a ViewModel, I could easily pass the "soon to be edited" object directly to the view without needing to fuss over setting individual properties etc as the View conveniently accepted the Employee type directly..
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(SomeEmployee);
But now I'm using a ViewModel with DataAnnotations attributes applied over the top of various properties for validation purposes. Which creates a problem.. After fetching the "soon to be edited" object from the db, setting the ViewModel's values is suddenly a whole lot more complicated. I can't simply pass the retrieved object straight to the view, as the View now expects the VMEmployee type instead. I would like to be able to do something like:
[HttpGet]
public ActionResult EditEmployee(int? id)
{
EmployeeRepository ER = new EmployeeRepository();
Employee SomeEmployee = ER.GetEmployee(id.Value);
if(SomeEmployee!=null)
return View(new VMEmployee(SomeEmployee));
All paths seem to lead to a huge constructor which manually sets the values of each individual property. But I never had to do that before when I wasn't using a ViewModel. Model binding was a blessing! My objects also have complex child objects, which my form is also collecting values for, so this would be a huge/verbose task against DRY principals. I don't even really want to use a ViewModel, but am forced to because I need two different DataAnnotations rule sets for different validation scenarios applied to the same object.
All I want to do is be able to have two different DataAnnotations rule sets for different scenarios. I.e. public-facing www site vs internal-facing admin site. DataAnnotations doesn't seem to be flexible enough to easily cater for this common need. I've tried AutoMapper, but it throws an error saying it can't map my object types, I suspect because Employee was auto-generated by LINQ to SQL. What is the most elegant way to achieve this while sticking to DRY principals?
