This might sound like a stupid question, is there a way to add an item to the very top of generic dictionary instead of adding it to end?
Here is my code snippet:

I want to add an item of ["", ""] to the very top of dicGetCategoryId.
Calling Index view is giving me this very very annoying error . Can anybody tell me what to do about it
Error:The model item passed into the dictionary is of type 'System.Collections.Generic.List1[MvcApplication13.Models.Groups]', but this dictionary requires a model item of type 'MvcApplication13.Helpers.PaginatedList1[MvcApplication13.Models.Groups]'.

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.
View 1 RepliesAt debug time I would like to see what are the keys in my InitParams collection - I can't seem to be able to list them.
EDIT:As Jon suggests below, this might be a bug within the Silverlight debugger. To reproduce, just create a new Silverlight Application within Visual Studio 2010 and just edit code

i having error throw on View page and i think i am passing wrong type.
The model item passed into the dictionary is of type 'System.Collections.Generic.List1[App.Domain.Model.Interface.IPerson]' but this dictionary requires a model item of type 'System.Collections.Generic.IEnumerable1[App.Domain.Service.PersonService]'.
MyService looks like this....

The following code has only thrown a NullReferenceException a handful of times over the last several months, but I'm not exactly sure why. The code isn't mine, but it looks pretty straight forward to me.

The only thing I can think of is that pageType is null when it's being used as a dictionary key, but apparently that is not possible.
The code that calls it is simple:
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
_mypage = GetPage();
}
I also thought that the error might be with the _section.Pages, but section is never null and never sets anything. If .Pages[page] returns null, the MyPage constructor simply returns. So what am I missing?

I notice that my generic list is maintaining only one item, i declared it in the aspx.cs page f one of my forms. I am assuming that each time the page is reloaded when I add an item the list is redeclared. How can I stop that?
View 10 RepliesI have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.
The InsertItem Template is in the first position, making it easy to insert a new record.
And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.
I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
which works fine also.
The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:
Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
Page.Validate()
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub
This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.
Here is the code for a typical entry of the InsertItem Template:
[code]....
All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"
How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?
I have a class that maintains a static dictionary of cached lookup results from my domain controller - users' given names and e-mails.My code looks something like:
private static Dictionary<string, string> emailCache = new Dictionary<string, string>();
protected string GetUserEmail(string accountName)
{
if (emailCache.ContainsKey(accountName))
{
return(emailCache[accountName]);
}
lock(/* something */)
{
if (emailCache.ContainsKey(accountName))

I have a problem:
I've created usual Controller and View(Edit view) for editing my Entity (EntityFramework)
Here is view example:
<div class="editor-field">
@Html.EditorFor(model => model.BirthDate)
@Html.ValidationMessageFor(model => model.BirthDate)
</div>
BirthDate is Nullable<DateTime>
but during loading my View I get this exception
The model item passed into the dictionary is null, but this dictionary requires a non-null model item of type 'System.DateTime'.
That's because of BirthDate is null in database but it is nullable and I expect that it just leaves the filed empty.
And I have Shared EditorTemplate:
@model System.Nullable<System.DateTime>
@if (Model.HasValue)
I have a listbox which populated from using a datatable. I have a Add button in my page. On clicking the add button I want to insert a blank row in the listbox. This can be done easily by

View 1 RepliesI want to take an already existing row in a RadGrid and instead of open an edit template I want to open the Insert template with that data.
I have a requirement to allow the user to make edits to the rows on their "key" values, the result being a new row that they didnt have to type everything over again.
My guess is to put an insert button on the row, but I'm not sure how to open the insert template and still have it bind that rows data to it.
i have dropdown list in my page that bind it from database
BindDropDownList(DDL3, "Guidcenter", "Centername", "ID");
DDL3.Items.Insert(0, new ListItem(" select all", "0"));
here when users don't select any thing from dropdown list in data base insert 'select all' text but i want if users don't select any thing from DDL in database insert NULL.
how do i get the selected item in the drop down list and insert it into database (togethi populated the drop down with the values from the tables in database. It is dynamic, not static.i have a button in the gridview called 'add'. so when user clicks on it the row (whatever columns in the row) would be inserted into database. i am doing insertion/create for this.
View 14 RepliesWhat I'm trying to do is: I have a listview control on my page and in my code behind, I created an SQLDataSource object which I defined its Select, Delete, Update and Insert Command strings. I then binded that datasource to my listview. When I load the page, it's obvious the select command works. however, when I perform the insert, the ItemInserted event triggers, but the itemInserted doesn't trigger and there is nothing inserted in my database.I'm not sure what to do here. I also hard coded the insert values in my insert command. So it's not depending on the form values.

View 1 RepliesI'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.
What is the difference between generic and non-generic collection?
View 1 RepliesI've been trying to find a solution to my problem for about 2 days now, and have found nothing. I am new to .net and not really sure how to accomplish this. I have 4 tables in a database, Vendors, RepairCos, Cons, ConRepairHistory. What I'm trying to do is make a page called SendOutForRepair.aspx that has a insert item template where the first control is a dropdownlist that is attached to the Cons table (got this figured out) and is populated with the Serial Number field. I would like the selection from the dropdownlist to populate the 2nd control (VendorID) that is also from the Cons table....
View 1 RepliesI have a web form for handling invoices which has a form view. When I'm in insert item template, I need to have various fields. Some of them are contract number, invoice number, register date and other that are easy to handle. But there is a dropdown list related with a table of prices (the table has price name, price initial payment, number of payments, amount of month fee and so on). So, when the dropdown is selected, fields related with price should get their values from price table, and then the user decides to keep them or type in new values. How can I get it done? Should I use a Dynamic populate extender or type all the code behind using SelectedIndexChanged method to populate price related controls?
