Hello

I have an ImageMap created using YDreams ImageMapDemo 2.0. I'm using this control for the rollover image effect with circle and polygons hotspots. My issue is I can't seem to figure out how to write the correct C# code for each hotspot. I am able to get one hotspot to have the rollover effect but not the other 4. Can someone please help me out with the code behind. I am very very new with C#. Anyone's help would be much appreciated. Been banging my head for 2 months.

Thanks in advanced

Dale

erm... if you're so new to C# ( there is no such thing as C+ ), why are you taking on this task ?

Odds are that most people don't even know the product you're using. Don't they have a support forum ?

YDreams does have a support forum for this control but it is on this site and no one seems to look at it. I found YDreams Imagemap 2.0 on the Code Project website( Here )and was hoping someone has used this control and if they could help me out with the issue I'm having.

It's unlikely. But, if the article is orphaned, then perhaps it's your best bet. I would be looking for something else to use, or googling to see if it's also posted elsewhere and supported there.

I would assume so long as you don't send .NET classes, if you just send plain data like text and numbers, you should be fine.

Even if you sent a class, it's just a matter of working out how to parse it from the XML.

Confused of dynamically added controls on AJAX page

Sorry for bad English, as it`s only 3rd language...

In every post regarding adding controls, it is written that I should add them OnInit event, however at that time, I do no know, witch control I must add. Frown | :(

If I add them on Button click, all shows as planed, but if I add them at ScriptManager OnNavigate event, they do not show up Frown | :(

It`s nothing to wory before something happen and when it happents it`s alredy to late to wory! Smile | :)

Here is some tips for adding dynamic control.
. You have to create all the control before Page_Load(), Preferably on Page_PreInit(). Because if we create any dynamic control after Page_load(), The control will not maintain, ViewState and Postback data. Because, View State and Post back Load just before Page_load. So, if we create any control after postback, it will not able to get the view state and postback data.

Let me know if you have any problem.

Hope this information will help you Big Grin | :-D

I know that Frown | :(

But I do not care about viewstate or Postback, all controls that should talk to server are in main page, not in update panel, only thing that do not work as wanted is ScriptManagers OnNavigate event. It fires too late. I need that event to handle f5, back and forward.

If controls are added as fallows:

protected void mi1_click(object sender, EventArgs e)
{
test();
}

all is ok Frown | :(

But in this case:

public void OnNavigateHistory(object sender, HistoryEventArgs e)
{
test();
}

it will not work Frown | :(

void test()
{

//This line works fine in both cases. It sets couple of properties, as label texts and session variables.
set_title("Test title");

//Instead of button I need my usercontrol, but even button will not show up.
Button btn = new Button();

btn.Text = "I bitīt matos!!!!!!!!!!!";

PHolder.Controls.Clear();
PHolder.Controls.Add(btn);
sm.AddHistoryPoint("aa", "bb");
}

It`s nothing to wory before something happen and when it happents it`s alredy to late to wory! Smile | :)

Try changing your ASPX file to this....

<asp:ImageButton ID="cmdSignUp" runat="server" ImageUrl="../../images/submit.gif" OnClick="cmdSignUp_ServerClick"></asp:ImageButton>

And then remove this line from your Page_load event....

this.cmdSignUp.ServerClick += new System.EventHandler(this.cmdSignUp_ServerClick);

i have got a requriment from the business where
i need to get an input from the user in the chinese
format and store the same into the database. The same should be shown when the user
clicked show button. The other information in the page cannot be a chinese but the input
i got from the user should be displayed in chinese.
My application is in ASP.NET and the database is in SQL server 2000.

i have no problem in displaying the data and storing the data into the database. The problem is how to get an input key in
by the user in the chinese format because the key boards by default will not
support that formats.

You can build menu dynamically from database using ASP.NET server side menu control.

Fill your hierarchical menu data from database into a DataSet and assign it to an XmlDataSourceusing DataSet.GetXml() method. Then assign that XmlDataSource to ASP.NET Menu control.

Check this article.

Long time to get DataSet While Stored Procedure takes 1 second.

By default, ASP.NET web site will run under ASPNET account in XP and Network Service in Windows 2003.

Therefore these accounts will not have permission rights to shutdown a remote computer. Run your web site under a account with appropriate permissions.
