I have worked with the .MVC framework using validation frameworks such as xVal or FluentValidation.
Is there anything similar available for webforms as well? I have got a few projects which have to be done using webforms.
What I'm asking for is some kind of integration with the webforms infrastructure. I could just use one of the mentioned frameworks in order to validate the (view/page)models, but I still would have to do a lot of form validation in the page.

how to use jquery in an asp.net nested masterpage. I have my main masterpage where I have added the link to the jquery libaray and also the validation framework. I have then created another masterpage with some styling and created a aspx page based on that masterpage.How can I attach the validation framework to textboxes within my page?
$("#aspnetForm").validate({
rules: {
<%=txtPostCode.UniqueID %>: {
minlength: 2,
required: true
},
<%=txtContactEmail.UniqueID %>: {
required: true,
email:true
}
}, messages: {
<%=txtPostCode.UniqueID %>:{
required: "* Required Field *",
minlength: "* Please enter atleast 2 characters *"
}

I need to implement a centralized form validation framework for my ASP.NET(C#) 3.5 website.
And for this I have tried the following solutions-
[URL]
[URL]
I have added the .dll file in my project's BIN folder and for Matt Gibb's solution I have also added the tagMapping code to web.config file. But for both of the solution, when I ran the project I noticed it doesn't have any effect on the validation controls.

I know this question has been asked million times but I think my situation is different here.I am using .NET Framework 3.5 SP1, there is no form action on the page and it's not happening when I try to submit the form quickly. I am not on a web farm either.I have a page with two GridViews. One Gridview acts as a master gridview and second as detail gridview. First Gridview has autogenerate select button and clicking select would bring related records in detail gridview at the bottom. I have a refresh Link button at the top. Everything works fine. I click refresh button and it works fine too.Ok when problem start happening when I leave the page idle for like 10 minutes or so and then I click Refresh button only then I get this "Validation of Viewstate MAC failed" error.

I have a form that I have been getting submissions that have punctuation and special characters that trigger the potentially dangerous Request.Form value error. I have been trying use the httpUtility.htmlencode and Server.htmlencode method to sanitize textboxes and textareas.All my tests do not fire because the built-in request validation of the 4.0 framework prevents the code-behind from executing to perform the sanitization. I have included the ValidateRequest in the page header but no matter what I set it too it still does the same thing.
This is the code I have so far.
Session("RequestID") = Server.HtmlEncode(txtRequestID.Value)
Session("FirstName") = Server.HtmlEncode(txtInstFirstName.Text)
Session("LastName") = Server.HtmlEncode(txtInstLastName.Text) [code]....
What can I do to make this work? According to all the websites I have visited it should work.

I have this SQL Select statement to select the basket id where the user id equals a specific ID.I want to store the result of the query in a variable, so I thought I could have done:
BasketPage.SelectCommand="SELECT BasketID FROM tblBasket WHERE (UserID = '9f96bd94-91b9-4328-8214-4eac179c3a26')"
var BasketID = BasketPage.ExecuteScalar().ToString();
But apparently I need to create a new instance of an SQL Command for it to work, how can I do this for the BasketPage Select Command?

I was looking to build an application with the scenario:
1. The application is a Shared PowerPoint Presentation
2. There would be 2 users for the application, Admin and Client
3. Admin can upload presentations
4. Only Admin can control the flow of presentation and cLient can just see the changes
5. As-In Admin can select next slide or previous slide and correspondingly Client configuration changes
I was thinking of updating current values in Database and using AJAX for updates on Client end. But I want a notification kinda thing that would notify the Client as soon as the Admin changes slides.

My scenario is this:
I have asp.net page which having the drop down control with Product list. in database my Product Table has fields as ProductId, Product Name and Price. where as I have filled this drop down control by this method:
private void FillProducts()
{
List<Product> productList = objProductManager.GetProducts();
if (productList.Count > 0)
{
drpProducts.DataSource = productList;
drpProducts.DataTextField = "ProductName";
drpProducts.DataValueField = "ProductId";
drpProducts.DataBind();
}
}
Which is working perfect. But i want to get selected product Price value on client side. for that I don't want round trip at server to get that. is any property of dropdown control other than DataTextFeild Or DataValueField to hold the Price Field of product ? so that i would avoid to go back at server. Or suggest any remedy for the same.

i'm new with design patterns and i'm not sure if in this situation i can use a composite pattern.
The scenario is a web application for an address book : the address book cointains AddressBoookItem, generalization for Contact and ContactGroup. The last one is the composite object containing a collection of AddressBoookItem.
With these scenario i'm sure that this is a composite pattern, but what is confusing me is that a contact may belong to many contactgroup. Does this request change the situation? Till now i thought that between the Leaf object and the Composite (in the composite pattern) there was a 1-to-m relationship (a composite may contains many leaf but a leaf is contained in only one composite object). Can i still use the composite pattern ? And, the last question,
How could i represent my scenario in a relational database? One table for the entire hierarchy or two table (Contact and ContactGroup) with a m:n relationship between them ?

I want to track equipment between three types of allocations. A piece of equipment can be allocated to an employee, to a customer facility or to a warehouse.
I have an equipment table, employee table, a customer table and warehouse table. Warehouse is where equipment is temporarily held and shared between multiple employees, it is a holding area.
Obviously each equipment item can only be allocated to one employee, customer or warehouse.
My original thinking was to make a table for EquipmentAllocations where it linked the EquipmentID and the id of the employee, customer or warehouse (all guids).
Eventually I will need to query the equipment to see where it is located/allocated. I will also need to query the employees to check what equipment is allocated to them.
I am trying to figure out the best way to handle this and I am looking for some guidance. I am sure many of you have had situations similar to this that you could draw upon to offer up some advice.

SaveChanges can generate an UpdateException when an object added to the ObjectContext cannot be successfully created in the data source. This can happen if a row with the foreign key specified by the relationship already exists. When this occurs, you cannot use Refresh to update the added object in the object context. Instead, reload the object with a value of OverwriteChanges for MergeOption.
In a table, a foreign key column can have a single value multiple times. e.g. DepartmentID foreign key in Users Table: More than one User can have same DepartmentID foreign key.
So how can this cause an UpdateException ?

I have created a great stand-alone web form in asp.net utilizing many jQuery features and CSS. It works fine. When I re-create it as a web content form as part of a MasterPage, my jQuery and javascript is completely ignored.
I am referencing the pertinent jQuery and CSS in my of the MasterPage. I have a content placeholder at the bottom of the masterpage called "ScriptContent". In my content page, this is where I plug in the various jQuery methods and javascript.
When I view the page source everything is there. However, it's all being ignored so to speak. What am I doing wrong?

I am using ASP.NET MVC with jquery. I have the following MVC Action that returns a partial page on Success. On Application Error, I am not sure what to send it for correctly handling it at the client side.
public ActionResult LoadFilterSet(int filterSetId)
{
try
{
BreadCrumbManager bcManager = this.ResetBreadCrumbManager(this.BreadCrumbManagerID);
GeneralHelper.LoadBreadCrumbManager(bcManager, filterSetId);
ViewData["BreadCrumbManager"] = bcManager;
return View("LoadFilterSet");
}
catch (Exception ex)
{
return Content("");
}
}
Following is my jquery ajax call. Notice that I am checking for the data length to make sure there are no errors. Please suggest me a better way of doing this.
$.ajax({
type: "GET",
dataType: "html",
async: true,
data: ({ filterSetId: selectedId }),
url: link,
contentType: "text/html; charset=utf-8",
success: function(data, textStatus) {
if (data.length > 0) {
// Clear the local filters first.
clearLocalFilters();
$('td.selected-filters table.filters-display').append(data);
}
}
});

I have a question about model binding. Imagine you have an existing database entity displayed in a form and you'd like to edit some details, some properties eg createddate etc are not bound to the form, during model binding, these properties are not assigned to the model as they are not on the http post data or querystrong etc, hence their properties are null. In my controller method for update , Id just like to do
public ActionResult Update( Entity ent)
{
//Save changes to db
}
but as some properties are null in ent, they override the existing database fields which are not part of the form post data, What is the correct way to handle this? Ive tried hidden fields to hold the data, but model binding does not seem to assign hidden fields to the model.

I have seen a particular pattern a few times over the last few years. In the UI, each new record (e.g., new customers details) is stored on the form without saving to database. This clearly has been done so not clutter the database or cause unnecessary database hits.
While in the UI state, these objects are identified using a Guid. When these are a saved to the database, their associated Guids are not stored. Instead, they are assigned a database Int as their primary key.
The form can cope with a mixure of retrieved items from the database (using Int) as well as those that have not yet been committed (using Guid).
When inspecting the form (using Firebug) to see which key was used, we found a two part delimited combined key had been used. The first part is a guid (an empty guid if drawn from the database) and the second part is the integer (zero is stored if it is not drawn from the database). As one part of the combined key will always uniquely identify a record, it works rather well.

almost typical master-detail scenario except the 'detail' data I want to display below the gridview will be coming from both the table that is bound to the gridview (master) and a related table.
simplified example: tableMain with field1, field2, field3 bound to master gridview. I need to select a row from the master gridview and have a form display below with field4 and field5 from tableMain, as well as all fields of tableDetail where field1 of tableMain equals field1 of tableDetail.
Is this what a 'formview' control is for? or do I just arrange my own controls to accommodate the data? Would a formview work considering my source will be partially from both the main table and the detail table? This is one of the scenarios were I know I could come up with something using none of the databound controls (except the master gridview), but I want to use the controls provided when it makes sense to do so, and utilize their benefits etc...
