hai,
currently i m using asp.net with c# 2005 (framework 2.0)

Hi all,

I'm working on a survey kind of program: There's a set of survey subjects and inside those survey subjects there comes a set of survey questions. What I wanted to do is chain those survey subjects together in a "previous" & "next" fashion, e.g. when I click the next button the page will display the next survey object and same thing happens to "previous" clicking. Is it possible to bind the data to some kind of navigate control or something like below (increment/decrement the VoteID and bind the radio list (survey questions) with another set of data)? What’s the standard way of doing this? Is there any samples? I’m completely new to ASP.net.

string strConn = ConfigurationSettings.AppSettings["ConnectionString"];
SqlConnection conn = new SqlConnection(strConn);
SqlCommand cmd = conn.CreateCommand();
cmd.CommandText = "GetOptions";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@vote_id", VoteID);
SqlDataAdapter da = new SqlDataAdapter(cmd);
DataSet ds = new DataSet();

conn.Open();
da.Fill(ds);
rblOptions.DataSource = ds.Tables[0].DefaultView;
rblOptions.DataTextField = "content";
rblOptions.DataValueField = "id";
rblOptions.DataBind();

But the "increment/decrement the VoteID" method has drawback once the VoteID's value is not consecutive.

Thanks,

I have created a usercontrol with some labels. I am using this control in a aspx page, and I want to set the text property of those labels thru session variables. Can anyone help? Thanks, Rohini

Are you facing any issue ?
Just create public properties for these Labels in the user control and set from the Page ?

Thanks and Regards

yes, I have created public property and am able to set its value as a static text. But I need to bring it from a session variable.

Can you post your code ?
Are you new to ASP.NET or never used Session before ?
Then just google for the topic
or
ControlId.Propertyname= Session["KeName"];

but first check for null or empty

Thanks and Regards

Hey, I was wondering if there was a way to display a session variable that is outputted directly as text.
Something like this
Session Variable is FirstName

Logged in as: {INSERT FIRSTNAME HERE}

I know I could use a label and set its text on the page load, but isn't there a simpler way using the <% %> stuff Big Grin | :-D

Like this? <%= Session["FirstName"] %>

Yes...That's exactly it! Thanks Big Grin | :-D

, can't believe it was *THAT* simple!

suppose I have two pages in my project:a master page and a content page; In the master page I have one textbox(named SearchTextBox) and on ImageButton(named SearchImageButton). And in the content page I have a textbox(named NameTextBox) and one Button(named LoginButton);
Problem description: In the content page, if I have finished input some words in the NameTextBox and press "Enter" key, the SearchImageButton will be fired and executed, not the LoginButton! This was not what I want.
My question is: How can I fired the LoginButton when I finished input words in the NameTextBox and press "Enter", not the SearchImageButton(I can only modify the master page)?

Ok check this url

Thank you for your answer!
I'v tried the example you provide. But it not suitable for my project. Maybe you doesn't understand my question.
My situation is between two pages, one is master page and the other is content page. We want to fire the button on content page when we press "Enter". Smile | :)

That was not exact code you required, you need to put your logic there
You are not having 2 pages, At the end master Page is like control in the content Page, you need to use java script for that just google it.

Thank you for your answer!
I will try to refer the logic you provide. But I can only modify the master page(because we have many content pages so...) Smile | :)
