Lets say I have a Web Application with a menu of products. When a user clicks a menu item, then create and display a dynamic set of controls in an Update Panel. I am currently doing this however the PostBack and recreation of controls is tedious and resource intensive.
Not sure about this but is it possible to build a webpage with controls on it, then display it in update panel or IFrame? Then on post back you wouldn't have to recreate everything all over again?
I use freetextbox control to rich text.When I insert an image with imagegalley it creates a link:
<A>http://www.freetextbox.com "target = _blank> FreeTextBox </ A>.
I think this may be a question for the architecture forum, but it feels a bit newb to me, so here goes.
I'm trying to write a utility class to use throughout my C# ASP.NET websites. I am having trouble getting intellisense to see the methods in my class. What I'm doing is creating a static class and putting it in a namesapce and with a using directive, importing that class into the code-behind of my web form. But it's not working. I would also like to minimize the visibility of the code i.e. use the least accessible access modifier necessary for use in my util class.

I've got a web app solution containing a class library project.
Whenever I rebuild the class library and then refresh the page, it takes ages the first time, and is then quick again subsequently.
It's almost as if the newly rebuilt dll is having to 'bed in' to the app.
I've learned asp.net from books available on the internet, but I didn't find a good book that teaches you some techniques or logic to follow to build an administration area to control the front-end.I mean they talked about security, membership and roles. but still they didn't show you how to manage anything that's not related to a database, anything that's related to a database you'll probably create a page to display some info from a db with some SELECT commands and another page for the admin to INSERT, DELETE, UPDATEbut how can I connect to the other controls from my admin panel.for example : a textbox in the admin.aspx will edit the value of a certain label in display.aspx
another example : I built a web user control to retrieve articles from a DB and another control to be placed in the admin page, which will let the admin add new articles and it will insert it to the database, how can I add more power to the admin page to control the number articles to display on the page, or to control the sorting of the articles, etc...If i could get a name of a book that helps me with the logic or basics of creating a page that works like my admin panel to control the front-end it would be great,

View 3 Replies1. I have a GridView on my page and it uses sqldatasource with parameterized query. What I want to do is, on page load (where nothing has been selected so no parameter supplied), I want it to query everything (something like SELECT * FROM [this_table]) but since my SelectCommand is something like
SELECT * FROM [this_table] WHERE [this_column] = @someParameters AND [that_column] = @someParameters.
Can I play around with default value to achieve something like that but how ? Now, when the page loads, it doesn't show anything (No Gridview).
2. On my page, I made something like (username, gender, address, and more) and one single search button. That means, no single control enable auto postback. What I am trying to accomplish is building dynamic query
(if username specifed -> SELECT * FROM [this_table] WHERE [username] LIKE @username).
If both username and gender are specified (SELECT * FROM [this_table] WHERE [username] LIKE @username AND [gender] = @gender) and you know the rest. How can I do this using GridView and SqlDataSource ? To my knowledge, I can only specify one SELECT statement in a sqldatasource.
create db driven meta keywords/description. I would store these records in a database, xml format i presume; since it would be per culture.How would i go about doing this?

I have on my asp.net a youtube embedded video using code as follows
However, instead of hard code them in my page, I want the video reference code "nTasT5h0LEg" below be flexible and dynamic using label1.text instead. Is this possible ? the following is the html code of the object. Is it possible to change it to
value=http://www.youtube-nocookie.com/v/"&Label1.text&"?fs=1&hl=en_US&rel=0
But intellisense says this is an error.
I'm trying to fix a problem with some code (not written by me)
lnkbtnPageNumber.ID = "PageNumberCustomerRef" + intPageNumber.ToString();
lnkbtnPageNumber.Command += new CommandEventHandler(lnkbtnPageNumber_Command);
lnkbtnPageNumber.CommandName = "DepotRef";
lnkbtnPageNumber.CommandArgument = intPageNumber.ToString();
lnkbtnPageNumber.Text = intPageNumber.ToString().PadLeft(3, '0');
lnkbtnPageNumber.Attributes.Add("style", "margin: 2px;");
pDepotRefPages.Controls.Add(lnkbtnPageNumber);
This code creates a link button, however when I click on the button on the page. The function lnkbtnPageNumber_Command is not being called. The scripts just not getting to it.
I've tried google but everywhere I've looked says that this code should work fine.
Here is the code which is being called by the function:
void lnkbtnPageNumber_Command(object sender, CommandEventArgs e)
{
try
{
switch (e.CommandName)
{
case "GlobalID":
gintDocketNumberPage = Convert.ToInt32(e.CommandArgument);
break;
case "CreatedDate":
gintCreationDatePage = Convert.ToInt32(e.CommandArgument);
break;
case "Accounts":
gintAccountPage = Convert.ToInt32(e.CommandArgument);
break;
case "CustomerRef":
gintCustomerRef = Convert.ToInt32(e.CommandArgument);
break;
case "DepotRef":
gintDepotRef = Convert.ToInt32(e.CommandArgument);
break;
default:
gintDocketNumberPage = Convert.ToInt32(e.CommandArgument);
break;
}
I've just read somewhere that this code won't work unless called from Page_Init which if true is a but of a pain cos I can't put this fuction in Page_Init...
In an email, I want my users to be able to click a link to confirm an interview schedule. How do I dynamically create these urls?
I am thinking of using a query string and I don't want them to have to login every time. So ideally, I'd like this query string to contain credentials, and a date and time. Of course, I'd like this to be encrypted in some simple way.
example: invitation.aspx?qs=24lkl254524j2re2wtl5y6.

I have moved to a new computer.. and I forgot how I setup the following within Visual Studio 2008...
on my previous computer:
[1]I have a MY_SITE solution
within that solution I have:
[2]T:MySiteFolder
[3]I have MY_SITEClassLibrary (which actually is just a reference to a folder that contains a lot of .cs files - that is within the T:MySiteFolderTheClassLibrary)
... then... if I have USING MY_SITEClassLibrary in any aspx.cs file, I can reference the various classes..
when I move to a NEW computer and a new visual studio 2008 installation... if I open the T:MySiteFolder website... it just opens as a normal website without the MY_SITEClassLibrary as a primary object......
so, can anyone remind me how to again setup this relationship within my new visual studio installation/computer?

I've successfully used the xmlhttp object to redirect (xmlHttp.open) user to another page but I have the following issue ..I have a classic ASP application that has some very antiquated "admininstration" functionality built in that loops through a SQL table with NT Accounts and allows the link to only be visible to users with NT account in the table. We have since moved on to manage permission to our .net apps using an object that looks for your NT account in an Active Directory Group. So, I would like to use the .net object to return True if NT account is a member of the group and then display the link (which is in the classic ASP page) if the .net object returned true.I don't know if that can be done .. I just know I'm able to return the TRUE value using the xmlHTTP ajax object but I only want to set visibility of a link rather than xmlHttp.open to redirect to another page.
