You can check it with SelectedIndex Properties.
if (RadioButtonList1.SelectedIndex > -1)
{
Response.Write(RadioButtonList1.SelectedIndex.ToString());
}
else
{
Response.Write("No Item Is Selected");
}

Hello, This Is Vikash Gohil.
I need some guideline/help on the following issue.
I have a webpage with a function written on Page_load event which takes the arguments from url using querystring and prints a single line on the page after execution of the function.
Now as per my knowledge, if i need to execute that function, i need to provide the full url in the address bar of the browser along with arguments needed.
Now what i want is, I dont want my webapp to redirect to that webpage but still need the function on that page, to get executed with the dynamically passed argument values.
Now, in first place, is this thing possible?
If yes, then can someone tell me the way to do it.
if no, then can i achieve this functionality in some other way?
All i want is the user must not be redirected, but still want to execute the function on another page.
Awaiting a reply soon, any help would be highly appreciated.
Thanks in Advance.

Whatever code you have written in the Page_Load event of the webpage should be removed and kept in a method in some other class. You can have something like Common.cs where you can put all the methods which are to be used across the webpages.

Hello, danish.
Thanks for your response.
But the problem is I cannot change any code as it is not my creation, it is like a 3rd party Control so i can only use it and not change anything.
But anyway thanks for the reply.

Hello, Chetan.
Thanks for your reply.
But what I want is not hiding the actual URL from the user.
My actual requirement is to execute code written in page_load event on another page without redirecting to that page.
Is this thing possible?
Please reply.

Use Server.Transfer

hi Friend's
Suppose i have one application which having session time out set as 45 min, now the scenario is suppose one user login and activate that session and close the browser without login off.
what happen to that session?
Is that session automatically terminate by garbage collection?
Or still remain active and if so then how to handle this session?
Thank's and regard's

Session will kill automatically after the defined time frame.

Session is maintained on server. So you don't need to worry about session time out. If the session is active and user close the browser, the particular session will automatically goes down when it reaches to session time out.
Now, if you want to perfrom some operation on session timeout or you want to clear the data base information while user log off the application, you need to handle the Session_End Event in global.asax and you may need to trap the browser close also.

Hi,
this should work (replace ids):
protected void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList comboBox = (DropDownList)sender;
GridViewRow row = (GridViewRow)comboBox.NamingContainer;
Label myLabel = row.FindControl("myLabel");
myLabel.Text = "myText";
}

The error i get starts in this line of code
dataSet.Tables[0].Rows[row]["a"] = txtBoxProduct.Text;
I've been told that this could be a problem in the number of Tables of the dataset, according to my XML file i should create 2 tables in DATASET.
any help please?
thank you.

Hey guys, am using a file uploader for a user to select a file,
But only the files in my working directory are allowed. If I

the path of the file could not be found...I would to choose a file
from different directories
Does any know what i can do on this one?
Please help

Hey thanks guys for ya reps, well i wish i would xplain this better,
Here is a piece of code:
below 'files' is the name of my file uploader
HttpPostedFile myFile = files.PostedFile;
string strFilename = Path.GetFileName(myFile.FileName);
if (strFilename != "")
{
string[] lines = File.ReadAllLines(strFilename);
}
Reason: As anyone one else knows, when you choose browse on a file uploader, you can only select a file if it is present in the dialog box that opens.
So if I select a file in my working directory, it works ok but if i select a file 'Outside' my working directory then I receive the error above(file not found).
E.g my working directory is: C:\MyProject\SMS Send\contacts.txt this works
and if I choose: C:\Documents and Settings\Morgan\Desktop\testing.txt this will give a FileNotFound exception,
and when i look at this exception it is pointing to:C:\MyProject\SMS Send\testing.txt which is my working directory. I don't quiet understand why it is searching for the file from my working directory..
Please help
Thanks
Mor

You need to user Server.MapPath() while retrieving the full path.
e.g:
string strFilename = Server.MapPath(Path.GetFileName(myFile.FileName));//path of a file
I guess this should work now.
When you fail to plan, you are planning to fail.

Thanks for your reply man but hey this gives me the
same error(FileNotFound Exception)
I don't quiet know why...
