I have been using properties and have idea that using properties with private fields we can implement validations and buisness rules in them.
But I am just thinking asp.net client side validation controls provide good strength and they provide good user experience as well. They can be used for any type of validation (using regular expression) on client side and their re-use is possible on server side. When validation controls are a must and they are powerful; is making properties not just wastage of time ?
Is there still some use of properties ?

Can anyone tell me why this doesn't work? I want to hide the pager in my gridview's footer, and display it elsewhere on the page. I have a table defined where I want to display the pager. The grid is displayed only after the search button is clicked, but that shouldn't matter since the Search button causes a postback, so the page is reloading, and therefore my function should be called, right?Here is my JQuery function:
$(document).ready(function() {
SetPager();
});

We have several asp.net web applications we've built and we also want to embed them into various sharepoint pages. We need to have them look like standalone applications when viewed in their own pages, but also have them look like they fit within the sharepoint page when embedded. We are doing this currently with IFrames and it works ok, but I'm wondering if there is some sort of proxy web part where we can configure the web part to point to an existing web app and it will proxy the contents through from the web app into the sharepoint page removing the need for an IFrame. Possible?

When using SPWeb.GetCatalog(SPListTemplateType.WebPartCatalog), it returns an SPList which of course contains a SPListItemCollection of the web parts in the web part gallery. When looping through the items, is there any easy way to get properties of the web parts? Such as AllowClose, CatalogIconImageUrl, etc... I know I can probably accomplish this using the listItem.OpenBinaryStream etc and loading the xml of the .webpart file, but I wondered if there was an easier way to do this.

i cant seem to selectively disable serverside validation using annotations. Data annotations and unobtrusive validation is an awesome feature and has worked out great for us thus far but trying to localize it has been fruitless.
Basicly i have a property in a model object like this (it wraps a DTO)
[Code...]
i can change the output text for things like data range, required, string length etc. but simple stuff like "this field has to be a number" seems hidden away.

i want to create a centralised business or Service authendication architecture in .net. for example, we have a clients like c1, c2, c3, c4, ... etc. everybody logins seperatly as well as grouply. ie, if client "C1" logins [with login authentication] he can access c2 , c3, c4 also without login authendication. So its like a google. if we enters gmail account, we can access orkut, picasa like that.. i need the cetralised architecture.
And, client "c1" seperately asks seperately how will be the authendication architecture.
so give me the single solution for both these two scenarios. how will be the architecture for these two and how is the Data Base (Login) Structure.

recently i've studied on ADO.NET's Entity Model Framework and say 'wow' as ORM is one of the fevourite pattern i practice..but suddenly i've come to an ambiguous situation when i'm going to start. i usually follow the following 3-tier architecture..
1. UI Layer
2. BLL - business logic layer
3. DAL - Data Access Layer
a. DTO / DAO
b. Gateway (contains the sql query/stored procedure and connection with DB)
now when i'm going to use the Entity Model Design,where the DBML/ .edmx File should be placed? Because many a times i'm using the DBML file as DTO because of the mapped objects.. in the same time, sometimes DBML ( .edmx file in .NET 4.0) contains CRUD methods and stored procedured method as well as methods with different selection operations,- which should be in Gateway. so where the .edmx file should be placed !?!! IN DTO namespace !? or in Gateway namespace!
moreover sometimes there is no need for the BLL which breaks the rules of inter-layer-communication (UI > BLL > DAL.Gateway)! what makes me confuse is, what should be the ideal n-tier architecture when i'll use the ADO.NET Entity Model Design Framework

I want to implement validations in setter of properties.
how I will do validations before setting value. but not getting what to do if passed value is not correct. Just not setting is not a acceptable solution as I want to return an appropriate message to user (in a label in web form). My example code is:
[code]....
A thought was to use return but it is not allowed.
Throwing error looks not good as generally we avoid thorwing custom errors.

1. Is it always required to use javascript to do client side validation.
2. If we dont want to use the script then can I write the code in c# for validating a control like text box using the events.
3. If I write the code in c#, does it always requires a postback?
how can I implement validations for controls in c#. I am not familiar with javascript, so is it good to write the validations in c#
