have some Objects, lets say Employee and Role defined as below and I have defined relationships in my database that gives me a list of objects say employees and thanks to my framework each employee object also has a Role object linked via the RoleIDID, UserName, Password, Email, RoleIDRoleID, RoleNameSo in code I can do something like this
Employee emp = dataService_GetEmployeeByID(1);
string RoleName = emp.Role.RoleName;
Now here is my problemI can bind any object in a repeater and it works fine for the first level in my relationship
For instance <%# Eval("UserName") %>
But I need to be able to show the details for my child objects as well (Role) so something like this (which does not work)
<%# Eval("Role.RoleName") %>
I know how to bind a simple objects to a dropdown list. However I am having problems binding my objects which contains sub objects to the control.i.e. with simple object i just do ddl.DataValueField = "myproperty"
with my objects they contains sub objects which i want to bind. I have tried ddl.DataValueField = "sub-object.myproperty" which doesnt work.
I'm binding a Dictionary to a drop down list.
Say for example I have the following items in dictionary:
{"Test1", 123}, {"Test2", 321}
I'd like the drop down text to take the following format:
Test1 - Count: 123
Test2 - Count: 321
I was going along the following path with no luck:
MyDropDown.DataTextFormatString = string.Format("{0} - Count: {1}", Key, Value);

Page with 1 button and 1 jQueryMobile ListView
On button click, send AJAX request to webservice to get list of names as JSON
Bind the list of names to jQueryMobile ListView.
I found a example of this but it wont work for me. So I will do a clean question by asking how do I bind a dictionary to a repeater?
I work with code behind so its for the OnItemDataBound. My Dictionary look like Dictionary<string, string>();
I have ListView control on my page, and i bound it to Dictionary<string,DataTable> generic.Now i'm trying to put DataPager on my page to support paging, but DataPager doesn't work properly, in particular, I have to click twice to move to next page, or first few records repeating thru every page. What's the problem, what am I doing wrong? I used ListView control before with ObjectDataSource and it worked just fine. Now I'm using Entity Framework to retrieve data frm Db.

I have a situation where I want to show the selected records out of total records for a product of an employee
1) There is a checkbox list bind to <List> of objects from object datasource (For total items in list)

3) For this purpose I have another list of <List> selected items returned by data access layer (For selected items for that employee )
4) How do I bind the selected objects with the total items list ?
5) In spaghetti coding model it was all too easy just by binding the checkbox list with a sql data source and running a for each on form load
I have a List of Customers. Now I want to display these customers in a gridview and that is easy. I just set the datasource and use the databind method of the gridview. (I use template fields). But now I want to display FirstName and LastName of the customer as one column.I am aware of how to use the rowdatabound event to manipulate the gridviewrow's controls, but I am not sure how to gain access to the customer object within this method.So here is some code which of course not works.
protected void grdVirtualCustomers_RowDataBound(object sender, GridViewRowEventArgs e)
{
System.Web.UI.WebControls.GridViewRow row = e.Row;
((Label) row.FindControl("lblName").).Text=Customer.FirstName + " " Customer.LastName;
}
I'm creating in my code a list of object which must be displayed later in a table.
In Winforms I'd simply bind the DataGridView to the list, and everything is fine.
However, when I try to set the GridView's data source to the list, nothing happens, and I can't find a way to do this with any of the procided data sources(Such as ObjectDataSource, etc.).
How can I bind a datalist control with a list of objects. I have a list of objects that contain a name, desc, and url for menu commands that I am trying to show in a DataList. I am getting the list from a WCF service so I have a list called something like menuList which consists of a List<MenuCommands>. I then do a menuDataList.DataSource = menuList and then a menuList.DataBind but nothing is happening. What am I missing here? I need to use a DataList because I need the commands to be selectable.

View 4 RepliesI am using a listview to which I want to bind the MembershipUserCollection which you get from GetAllUsers(). I don't want to use reflection, I want to assign it in the ItemDataBound event of my listview. I've done this before, but with datatables. The code will be something like DataRow dr = (e.item.DataItem as DataRowView).Row. You can then access specific columns with
dr["ColumnNamehere"].ToString().
But how do you do this with MembershipUserCollection?
I have a ListView where I am trying to implement Updating. My update parameters are not sent to update command correctly. The value sent is the original value and ignores what I type into the EditItemTemplate. Running a trace on my SQL Server verifies this. In this example, I am only trying to modify [dedamt]. What is wrong?

I am trying to do this with many issues of data binding doubling the amount and not setting selectedValue on dropdownlist. I have read some posts and they help but I am missing a crucial piece. My problem is that my dropdownlist is doubling the amount of records for the dropdownlist. Instead of "YES;NO;SELECT A VALUE", I am getting "YES;NO;SELECT A VALUE;YES;NO;YES;NO". My database is correct with the UPDATE part but the rebind after update is failing horribly.
