I have two listviews. What i want to do is that when the nested listview emptydatatemplate shows i want to put a hyperlink with a querystring in it, the id in the querystring should be the fk in the nested listview. Is it possible to bind the hyperlink with the id in codebehind? I use two object datasources. Does it matter where i put the nested listview now i have it in the parents itemtemplate. Also it seems to be a problem to set the datakeynames in the nested listview, what could be the reaso for that.

From what I understand within the Gridview Object you can have many datakeynames.
I have the field like this DataKeyNames = "id1, id2"
However, i don't know how to access the DataKeyNames individualy. For example. How do you access the first ID for the for a given row or the 2nd ID for a given row????
I have these line of code:

When i debug i get an error that says: 'System.Data.DataRowView' does not contain a property with the name 'job_id'and sometimes 'System.Data.DataRowView' does not contain a property with the name 'pub_id'I need to get the appropriate value for the selected row. GridView only output Jobs results or Publishers results, the problem is when the user clicks select button beside the record, i get the error i mentioned above.

I have two columns in my Gridview marked false for the visible property but which are clearly listed in the DataKeyNames that are still getting set to null in my database table on update.
The first one is a column MId# which is a type int. It starts as 0 but on edit is turned into null. The Second is RequireSKU which is also converted to null.
When the page is displayed have labels, textboxs, and dropdownlists on top part of the page then the gridview at the bottom with the page numbers at the bottom of the gridview. Create the columns and add data to the gridview programmatically with several hidden columns. Use DataKeyNames on the source page and use DataKeys in VB.Net code behind to get data from the hidden column cells of the selected row. On the
first page when a row is selected, the textboxes and dropdownlists have thecorrect information from the gridview hidden columns. When select another page from pages numbers at the bottom of the gridview and select a row from the new page, get theinformation from the hidden column from the first page andcorrect data from the columns that are displayed onnewly selected page.
how can I specify DataKeyNames for a GridView when using a dictionary as DataSource?
[Code]....
In this example I would like to use "cat", "dog", "llama" and "iguana" as DataKeys for the four rows.
I have a gridView, with two DataKeyNames: MemberID, and CommitCustomerID.
One DataList has this sql statement:
SELECT * FROM [tblMemberProfile] WHERE MemberID = @MemberID
It pops up perfectly fine.
I also have another DataList with this statement:
SELECT * FROM [Incidents] WHERE CustomerID = @CommitCustomerID
I know this sql command works I have tested it with my data.
However I dont think the DataList is getting the proper value for the selected row in this DataLists case.
How can I make sure when I select the row in the GridView the proper parameters are going to the proper DataList sql statements?

Since I am using 2 DataKeyName is Gridview, so I have to pass both the DataKey while deleting Row from Gridview(using "Image Button" of Gridview).I tried it using below lines:
string name = GridView1.DataKeys[gvrow.RowIndex].Value["G_Name"].ToString();
string id = GridView1.DataKeys[gvrow.RowIndex].Value["Param_ID"].ToString();
I am did Gridview delete and rebind data using json and jquery like this
<script type="text/javascript">
$(document).ready(function () {
$(".deleteGridRecord").click(function () {
//Get the Id of the record to delete
var record_id = $(this).attr("id");

But i want to set DataKeyNames properties of grid view in above code dynamically how can do this....
How to get grid view datakey value in nested grid view in gridview_RowCommand

I use a ListView along with an ObjectDataSource tied to a business object. This object is defined as follows:
public class Employee
{
public int Id;
public string Name;
}
When I try setting the DataKeyNames property of the ListView to Id, ASP.net blows up and says: DataBinding: 'Employee' does not contain a property with the name 'Id'. However, when I change the object to that:
public class Employee
{
public int Id {get; set;}
public string Name;
}
It works!!!I couldn't find any documentation about this behavior. Why is it not accepting a simple variable for DataKeyNames and instead it insists on a property?
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
I am using VS 2005.I have 5 tables depending on their values ,I need to draw a bar chart.
View 1 RepliesUpdates 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.

Let say below the Employee Name, there's a GRIDVIEW, and that gridview contains Number of Leaves.
So when I click the number of leaves it will pop up.
So my question is how can I get the value of leaves and ALERT that number using jquery.
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.
