I am working on a project in .NET (C#), connected with a database. And I am entering values in database through 'text-box' control, for a part of the project. What I want is to check if the user entering value already exsists in the database and if so, shows error during that time only.
I have searched for any familiar post here, that could solve my query, but didn't get any.
my EXACT objective(if not cleared earlier):-
when the user enter the value in
textbox, automatically an event to
check any duplicate records in
database should occur. And if found,
displays an error message
how can i retrieve the all foreign keys against a single primary key. i mean to say that if a table contain a primary key then it becomes as foreign keys in which tables.
i want to take that nam of that tables and on the base of that tables then i am to delete from all the entries. e.g: if a primary key's column entry deleted then all foreing key entries should also be deleted.
there are 988 tables in a single database. it can't be possible to go for each table to setup foreign key to ON DELETE CASCADE.
.can it have any way to delete against foreign key priority wise? mean to say that parent table contain primary key, child table contain foreign key , now there is another child table which dependent previous child table. then how can i delete all record against it?
i want to do it from programatically. i am using sql server 2005
i have completed this till to that , it retrieves all foreign keys but how to delete now on the base of priority.

I noticed a behaviour in Visual Studio that the design tab for aspx page does not work if I use a dynamic master page using a base page. I dynamically set the master page to implement theming. It shows a master page error and says "The page has controls that require a Master Page reference, but none is specified".
Is there any solution? Or any work around?
I currently set the base/master page to a default master page in the page for myself and work on the page. Once I complete the page, I remove the master page attribute. I wanted to know if some better method is available.

View 2 Repliesafter a DetailsView (DV) 'Insert' (triggered by a DropDownList (DDL)) the DV shows the first record (in the DDL)!Are there VS2008 means to keep / show the just entered data - again ready with the command row "Edit/Delete/New" enabling me to e.g. "Edit" the just entered data?This DDL/DV scenario works just fine but to show my just entered record I have to leave this page and start calling this .aspx page again in order to see the name in the DDL and, hence, in the DV.I.e.

I have a drop down list and a textbox on a form. If a user select employee in the dropdown box, I wish to add employee email addresses in the text box. It should do the same if users select client on the drop down (i. e. Add client addresses in the textbox). I have not been able to do it without having to click on a button.
Here is the code that should be executed:
protected void ddTemplate_SelectedIndexChanged(object sender, EventArgs e)
{
if (ddTemplate.Text == "Employees")
txtEmailAddress.Text = "employee@abc.com";
else if (ddTemplate.Text == "Clients")
txtEmailAddress.Text = "clients@abc.com";
}
My prob is that when data inserted in database after that without any button click the new record show in popup box ?

Now this AddGridAddBTN Temporarily adds a data row to a grid but won't submit that data to database, however AddGridSubmitBTN Submits the data to DB through foreach loop .
Now my query is i want to provide user a functionality that when he gets focus on Abbreviation Text Box OR Description Box and he after typing some data Press ENTER KEY , This ENTER KEY would provide funcionality as a AddGridAddBTN Button , and when he presses SHIFT + ENTER , It works like AddGridSubmitBTN Button , also i want to make Abbreviation and Description Field to be filled must !
Moral is that :
ENTER KEY WOULD DO : Generate a temporary row with holding previous values as it is actually doing on AddGridAddBTN Button.
SHIFT + ENTER WOULD DO : Enter the whole grid data thorugh foreach loop as it is actually doing on AddGridSubmitBTN Button.
I don't want to refresh my page on enter or shift enter pressing . This grid is binded through SQL DATA SOURCE ...
I am new in asp .net.I am not able to undestand why we call base class method when we
override methods/events.Like automatically visual studio will put base.OnInit() if you are overriding OnInit.
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
}
same is the case of Finalize. In derived we call base.Finalize() Is there any need of calling these base class methods ?
I have to implement User base security in my Web project using .Net3.5. Followings are some we need:
Roles can be Admin, Manage, Editor, Member etc User can have multiple roles Every roles has its own dynamic menus and restrictions/resources All menus and interface will populate dynamically from Database
I heard some where this kind of i.e user base security can be implemented using HashTable but I dont know how is it?
Today I came to know that for this kind of work Java people use Interceptor Design patterns. So, how could I do the same in asp.net C#?
