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,

Are you facing any issue ?
can you post some code that you have written ?
At least put some efforts to write/learn javascript.
Thanks and Regards

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 
|
|
|
|
|
Like this? <%= Session["FirstName"] %>
|
|
|
|
|
Yes...That's exactly it! Thanks , 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)?
|

|

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". 
|
|
|
|
|
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...)
|
|
|
|
|
I think there is some confusion at your side ...
are you new to ASP.NET ?
if you are using Master Page in the application then there must be many content pages in the application.
TOALPCWJ wrote: But I can only modify the master page(because we have many content pages so...)
This is confusing statement from your side
Just modify the Content Page also is there any issue into that ?
Please let me know
Thanks and Regards

Yes, I'm a freshmen to ASP.NET.
I mean our project only have one master page. Because our project also contains a lot of content pages, so if I can just modify master page to achieve my result rather than modify so many content pages, that will save a lot of work and much better.
Thank you for your concern!
Thanks!

Hi,
During the launching of my web app in debug mode I have "one million" of System.TypeLoadException in system.web.dll and System.ArgumentException in mscorlib.dll ?!!
It is a web application hosted by IIS7 on Vista 32 bit.
If I stop the debugging, it works outside VS 2008.
If I call the first page on my site outside VS, I can launch my app in debug mode from VS and it works.
If I do a modification in my code during the debugging (even an aspx file) it takes many time to reload the page (again the system.typeloadexception many many many times...)
How can it possible ?
And How can I catch the error ? Call stack ?
Is it some errors from my code or a configuration problem ?
Thanks in advance,
Yannis.

On a Web page that accesses a SQL database, I get the following error in IE7 when I click on the paging numbers.
"Microsoft JScript runtime error: 'theForm.__SCROLLPOSITIONX' is null or not an object"
In WebResource1.axd, the execution stops on the scrollpositionx line below:
function WebForm_SaveScrollPositionOnSubmit() {
theForm.__SCROLLPOSITIONX.value = WebForm_GetScrollX();
theForm.__SCROLLPOSITIONY.value = WebForm_GetScrollY();
if ((typeof(this.oldOnSubmit) != "undefined") && (this.oldOnSubmit != null)) {
return this.oldOnSubmit();
}
return true;
The same page works fine in FireFox 3.0.3. I have seen others on the net that have encountered the same problem, but I have found no resolution.
Any suggestions?
Sincerely,
Stephen M. Golden

I think WebResource1.axd contains some JavaScript functions that are not compatible with IE7. Can you debug the JavaScript?
