You can create public properties and then set it and use it in the user control.

Hi Guys,

This is the first time i am working on asp.net project with oracle as backend. anyways my problem is that i am not able to insert data into oracle tables.

This is what i am doing.
I have a class file in which i have defined a function for insertion by calling stored procedure i ahve written at the back end

And i am calling the function written in class file from the aspx page by creating object of the class and calling the function. Now the error which i am getting says this: Length cannot be less than zero. Parameter name: length

Yes, but are you using percentage or absolute widths.

If you use percentage widths, then it will expand to the width of it's container (in your case, i'm guessing the screen).

If you use absolute, then it will always occupy that many pixels on screen.

Dear girish,

Firstoff all U should have to pur your all control within table tag means in & second thing U should have to give your width of the control in % (percentage) not in Pixcel(100px)

did u do that ????

if you are directly drag and drop the controls on the webform then they may be get disturb after change in resolution....

Server.Transfer is often a better choice than Response.Redirect.

Example:Let's say you're on A.aspx and you want to send the user to B.aspx.

Response.Redirect flow
A.aspx calls Response.Redirect("B.aspx",false); which sends a 302 redirect header down to the client browser, telling it that the asset it has requested (A.aspx) has moved to B.aspx, and the web application terminates. The client browser then sends a request to the webserver for B.aspx. IIS tells asp_wp.exe to process the request. asp_wp.exe (after checking authentication and doing all the other setup stuff it needs to do when a new request comes in) instantiates the appropriate class for B.aspx, processes the request, sends the result to the browser, and shuts down.

Server.Transfer flow
A.aspx calls Server.Transfer("B.aspx");. ASP.NET instantiates the appropriate class for B.aspx, processes the request, sends the result to the browser, and shuts down.

Note that Server.Transfer cuts the load on the client and the server.

Server.Transfer is easier to code for, too, since you maintain your state. Information can be passed through the HTTP Context object between the pages, eliminating the need to pass information in the querystring or reload it from the database.

response.redirect("");
In this method the redirection to the page is sent to the browser.
From the browser it is redirected to the page.

i.e Process goes like this

Server -> client(browser) -> Server -> client(browser)
set redirect the page Page is loaded
redirect
command to
the browser

server.transfer("");
In this method the redirection to the page is done in server, so the
redirect page is sent to the browser

i.e Process goes like this

Server -> Server -> Client(browser)
Transfer transfer Page is loaded
the page page is sent

Note:-
So response.redirect("") does call to client and then to server for loading
, server.transfer("") does not call to client, but transfer in the server and load that page to the client
