I Have a dropdown which the user can add items to using AJAX but I need to prevent Duplicates.
the dropdownlist.Options[index].value returns a number because of the way i'm databinding (i cannot change this).
Is there a Javascript property for the Name That will get me the text in the option tags rather than the value?

The following function is called upon the onBlur event of the textbox control (txt).
The following code does not work. Description of the function is: Search the ddl (an asp dropdown) for duplicates of the text in txt (asp textbox). Btn is an Asp.net Button that produces a postback and triggers the update panel in which only the ddl resides.
function CheckCaller()
{
var txt = document.getElementById("txtAddCaller");
var btn = document.getElementById("Button1");
var ddl = document.form1.ddlCaller;
var caller = trimAll(txt.value);
var found = "false";
if (caller != "")
{
for (i=0; i

Hello,
I have an ASP.NET app where I want to display a few labels and images on a page if the user hits the back button on the browser. How would i be able to capture the back button event of the browser on my app ? As in, If someone hits the back button, will any event be fired or can I have a javascript that can capture this event ? iam a little new to ASP.NET so sample code will help too !!!
this is my situation
Page(A)---> Page(B)
if someone presses the back button on Page(B) i want to show Page(A) with certain modifications. Thanks for your help !!!
Regards
RH

I have two Images that are in Itemtemplate one is sad.gif then the other is laughing.gif. then in EditItemTemplate is a RadioButtonList with two RadioButtons Good Mood and Bad Mood. all are in the same column. This is how it is supposed to work when Good Mood is selected, and insert button is pressed, the image laughing.gif is to be chosen. This code was supposed to work but I don't understand why it's not working:
<asp:Image id=Image1 runat="server" ImageUrl='<%# DataBinder.Eval(Container.DataItem,"MoodToday")=="Bad Mood" ?"sad":"laughing" +".gif"%>' ImageAlign="Middle" Visible="False"></asp:Image>
But whether I select Good Mood or Bad Mood only the image laughing.gif is selected. Where could I be going wrong?
Thanks

I think that the problem is that the Eval method returns a value of type Object, and when you compare that to a string, it will compare them as objects, not as strings. Even if they have the same value, they are not the same object, so the comparison always fails.
Try casting the value from Eval into String.

Thanks Guffa
It has worked. This is how it worked I had to select Bad Mood By default and the code would be:
<asp:Image id=Image1 runat="server" ImageUrl='<%#"/Images/"+((string)DataBinder.Eval(Container.DataItem,"MoodToday")=="Bad Mood" ?"sad":"laughing") +".gif"%>'>
</asp:Image>
Thanks a lot.

Why is it that when I insert data I fast get an error :
Specified cast is not valid.
But When I run it the second time I find the data was saved the right image was selected! Actually I can say every thing works well apart that when I atempt to insert data this error appears: Specified cast is not valid. on line:
<asp:Image id=Image1 runat="server" ImageUrl='<%#"/Images/"+((string)DataBinder.Eval(Container.DataItem,"MoodToday")=="Bad Mood"?"sad":"laughing") +".gif"%>' ImageAlign="Middle">.
Thanks

Hi i have doubt in sqlserver database roles...,
in my sqlserver for a paricular database,i created two application roles..and i given permission for those roles also..,
Now how to tell the roles in my form code.....,
(i.e) how to interact with those roles from my .net codes...,
I dont know how to interact with those roles...,
so plz give me some idea..,if any sample codes will be there...,
it will be more usefull for me...,
Magi

Hi Magi,
You can achiev this by queryig "sysusers" table from the database.
All the roles are stored in this table.
So you can create sqlcommand for the query "Select * from sysusers" and get them in the form of datatable or datareader.
SqlCommand cmd = new SqlCommand("select dbid, name from sysusers");
I hope this will solve you issue.
Thanks and Regards,
Chetan Ranpariya

How to access a file residing in the client machine, when the path of the file is given through asp.net. But not through fileupload control.
Can any one help me in this code
|
|
|
|
|
You can't access files on the client machine in asp.net. To do that would be like a virus or spyware. You would have to use some javascript or activex controls. Again these would look like spyware to users. The user must upload the file from their machine to your web server, then you can access the file on the web server.

But when a client wants to upload a file to the server. He needs to use the application. Is there any way to do that? If there are activex controls, can you please name them
|
|
|
|
|
If you are using .net 1.1 then you just use a control like this:
If you are using .net 2.0 then you can use the FileUpload control.
Hope that helps.

Hello
I've posted the question already, but i get no answer. Maybe it was not clear, what's my goal. Thats why I ask again (a bit different;)).
I'm sure most of you know myspace.com. There it's possible to visit a userprofile directly over doaminname/username (e.g. http://www.myspace.com/username). I want to build something like this for my own website. I red about URLRewriting, to change the URL into the global.asax (Application_BeginRequest). But this is only possible, when the Directory whith the specific username exists, and into it, there have to be a default.aspx File. Is this right?
Do I really have to create all these Directories and Files? Its not a big work, but it doesn't look really nice.
I thought also about the possibility to change the 404Error File into an .aspx File and handle it there. Is this the solution?
Or which is the right/professional way?
Best regards
succo

No part of the path needs to exist (except for the domain of course). Here's some code from a URLRewriter I wrote recently (it sets UICulture based on a url) that hopefully gives you enough hints on how to do this. If you still have questions, send me an email at support [at] stratelogics [dot] com and I'll help you out.
<code>
public class URLRewriterHttpModule : IHttpModule
{
public void Init(HttpApplication context)
{
context.BeginRequest += new EventHandler(context_BeginRequest);
}
public void Dispose()
{
// TO DO: Dispose resource if required
}
private void context_BeginRequest(object sender, EventArgs e)
{
HttpRequest request = ((HttpApplication)sender).Request;
HttpContext context = ((HttpApplication)sender).Context;
string applicationPath = request.ApplicationPath;
if (applicationPath == "/")
{
applicationPath = string.Empty;
}
string requestPath = request.Url.AbsolutePath.Substring(applicationPath.Length);
LoadCulture(ref requestPath);
context.RewritePath(applicationPath + requestPath);
}
private void LoadCulture(ref string path)
{
if (path.Contains("_e.aspx"))
{
// Set culture to English and remove _e from filename
Thread.CurrentThread.CurrentCulture = new CultureInfo("en-CA");
path = path.Replace("_e.aspx", ".aspx");
}
else
{
if (path.Contains("_f.aspx"))
{
// Set culture to French and remove _f from filename
Thread.CurrentThread.CurrentCulture = new CultureInfo("fr-CA");
path = path.Replace("_f.aspx", ".aspx");
}
else
{
// Leave culture as is and don't modify filename
}
}
// Set the UICulture to match the Culture
Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;
}
}
</code>
Dont forget to put this in your web.config's system.web section:
<httpModules>
<add name="URLRewriterHttpModule" type="URLRewriterHttpModule, App_Code"/>
</httpModules>

chklist1 = CType(DisplayPanel.FindControl(ds.Tables(0).Rows(index).Item(0).ToString), CheckBox)
If Not chklist1 Is Nothing Then
chklist1.Text = ds.Tables(0).Rows(index).Item(0).ToString
If chklist1.Checked = True Then //here showing that not checking even thought i will check check boxes

Hi Hafneef,
Are you saving values of check box i.e in database or XML file .
You need to save check box values and when you reload them dynamically then you need to put those values into check boxes.
Tip:
Check if you are missing "Ispostback"
