Query Data to Combobox using LINQ Query - linq

I am having trouble trying to add/query data from my database using LINQ to Entities to my ASPComboBox. Very noob and doing this for the first time. Does anyone know why this is having issues? My combobox is not being populated at all.
DEVEntities db; //no model namespace in front of db name
protected void Page_Load(object sender, EventArgs e)
{
GridViewOrgSearch.DataBind();
BingoSearchTest ecrm = new BingoSearchTest();
LoadPStatus();
}
void LoadPStatus()
{
db = new DEVEntities();
if (!IsPostBack)
{
var processingQuery = from p in db.BingoLOVs
where p.Category == "ProcessingStatus"
select new { Name = p.Text, ID = p.ID };
ddlProcess.DataSource = processingQuery.ToList();
ddlProcess.ValueField = "ID";
ddlProcess.TextField = "Name";
}
}

How can I limit the rows to one in database?

I have a table named profit model:
I would like to active different profitmodel, and the data in table will be updated.
Now I am using UpdateAsync, but it doesn't work... How can I achieve this?
async void Active_Clicked(object sender, System.EventArgs e)
{
var profitmodel = (sender as Button).CommandParameter as ProfitModel;
await conn.CreateTableAsync<ProfitModelInUsed>();
//System.Diagnostics.Debug.WriteLine(product.ProductName);
var profitmodelInUsed = new ProfitModelInUsed
{
ProfitModel_ID = profitmodel.ProfitModel_ID,
ProfitModel_Name = profitmodel.ProfitModel_Name,
ExchangeRate = profitmodel.ExchangeRate,
Profit = profitmodel.Profit
};
await conn.UpdateAsync(profitmodelInUsed);
await DisplayAlert("This ProfitModel is Applied", profitmodelInUsed.ProfitModel_Name, "OK");
}
And I don't want to have more than one rows in this table.
Apply a PrimaryKey to your ProfitModel_ID property within your ProfitModelInUsed model:
public class ProfitModelInUsed
{
[PrimaryKey]
public string ProfitModel_ID { get; set; }
// ~~~ other properties
}
And set the ProfitModel_ID property using a const:
profitmodelInUsed.ProfitModel_ID = "InUseProfitModel"
await conn.UpdateAsync(profitmodelInUsed);
Retrive it via:
var profitmodelinuse = conn.FindAsync<ProfitModelInUsed>("InUseProfitModel");

Load Database Values in Ajax Cascading DropDown

This is the first time I have used Ajax, and this is also my first C#.NET project, so I am very new. I am using .NET 4.0.
I have succesfully implemented the Ajax cascading dropdown, and upon submit, the data is stored in the database. However, this page also has an "Edit" feature, meaning if there is a value for said dropdown already populated in the database, it "should" display, and allow the user to change it. This is where I get stuck. If there is already a value for these dropdowns in the db, how can I display that?
I do have a try/catch for my other non-Ajax fields, and I have tried that on these, to no avail. I'll list that as well.

I decided to scrap the idea of a web service, and opted for an updatepanel instead. There is likely a less redundant way to do this, but it's working.
Final Solution:

Trying to retrieve result using linq

Hi I have a table which has a column AllowStockEdit which is a bit
I am trying to check is a user has edit access and then show edit and delete buttons on a radgridview
this is the code I am using
protected void AccessLevels(object sender, EventArgs e)
{
LINQDataContext dc = new LINQDataContext();
UserPermission up = dc.UserPermissions.Where(a => a.ID == (int)Session["Permission"]).SingleOrDefault();
up.AllowStockEdit = true;
}
/*show hide buttons */
protected void SelectedStockGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// show the edit button when user has correct access level
if
{
Button btnEdit = (Button)e.Row.FindControl("ShowEditButton");
Button btndelete = (Button)e.Row.FindControl("ShowDeleteButton");
btnEdit.Visible = true;
btndelete.Visible = true;
}
}
}
I am trying to check to see if the user has edit access if they do show the buttons
any help appreciated
Something like that:
protected bool AccessLevels()
{
LINQDataContext dc = new LINQDataContext();
return dc.UserPermissions.Where(a => a.ID == (int)Session["Permission"]).SingleOrDefault().AllowStockEdit;
}
protected void SelectedStockGridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// show the edit button when user has correct access level
if(AccessLevels() == true)
{
Button btnEdit = (Button)e.Row.FindControl("ShowEditButton");
Button btndelete = (Button)e.Row.FindControl("ShowDeleteButton");
btnEdit.Visible = true;
btndelete.Visible = true;
}
}
}

Unable to show the selected item in the Wp7 Listpicker control

Basically i am trying to pull the contacts from the phone and showing them in the Listpicker control for a feature in my app. I have two Listpickers, one for name of contacts list and the other showing the list of phonenumbers for the chosen contact.
Here is my code:
//Declarations
ContactsSearchEventArgs e1;
String SelectedName;
String SelectedNumber;
List<string> contacts = new List<string>();
List<string> phnum = new List<string>();
public AddressBook() // Constructor
{
InitializeComponent();
Contacts contacts = new Contacts();
contacts.SearchCompleted += new EventHandler<ContactsSearchEventArgs>(contacts_SearchCompleted);
contacts.SearchAsync(string.Empty,FilterKind.None,null);
}
void contacts_SearchCompleted(object sender, ContactsSearchEventArgs e)
{
e1 = e;
foreach (var result in e.Results)
{
if (result.PhoneNumbers.Count() != 0)
{
contacts.Add(result.DisplayName.ToString());
}
}
Namelist.ItemsSource = contacts;
}
private void Namelist_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
SelectedName = (sender as ListPicker).SelectedItem.ToString();
phnum.Clear();
foreach (var result in e1.Results)
{
if (SelectedName == result.DisplayName)
{
phnum.Add(result.PhoneNumbers.FirstOrDefault().ToString());
}
}
Numbers.ItemsSource = phnum;
}
private void Numbers_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
SelectedNumber = (sender as ListPicker).SelectedItem.ToString();
}
Am able to populate the Numberlist with phonenumbers for the chosen name at the Listpicker background, but the number is not showing up in the front. I think Numbers_SelectionChanged() event is called only one time when the page loads and am not seeing it triggerd when i change the contact list. Anyone has an idea of where am going wrong ?
If you change
List<string>
To
ObservableCollection<string>
this should work.
Also then you only need to set the ItemSource once, in Xaml or you constructor.
But you may run into another issue with the November 2011 Toolkit and ListPicker.
See more in thread.
private void Namelist_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
SelectedName = (sender as ListPicker).SelectedItem.ToString();
phnum = new List<string>(); // Changed instead of phnum.Clear()
foreach (var result in e1.Results)
{
if (SelectedName == result.DisplayName)
{
phnum.Add(result.PhoneNumbers.FirstOrDefault().ToString());
}
}
Numbers.ItemsSource = phnum;
}
This works !!. While debugging i found its phnum.Clear() giving a problem. So i thought to create a new instance of phnum list for selected contact.

Sharepoint 2010 Custom Webpart - Access Denied Error

we've created a custom webpart to display announcements from all lists a user has access to, removing a few. The error we are having is that the webpart works fine on the page for the administrators, but when testing with regular user accounts, they are unable to see the page at all and are given a Access Denied error which is coming from the webpart itself.
Only when a user is added as a Site Collection Administrator they can see the page and have access to the webpart. What I'd like some advice on is how to be able to apply full read permissions to a select group within the code itself.

SPWeb.GetSubwebsForCurrentUser() should be used. It gets SubWebs that current user has access to. Avoid using ElevatedPriveleges until you absolutely need it.
