You should get firefox and firebug. If you did, you would see that a seperate js file is never parsed, so your code is being written verbatim. One way around this is to do something like:

var=document.getElementID(textBoxClientId).value;

Then write a variable called that using the ClientID in the code behind of the page.

Also, NEVER use the result of getElementByID without first checking that it's not null.

Image button inside an updatepanel

Hi all,

I've just started playing with AJAX and am using the update panel to display images if a condition is met. The user can then click on the image and bring in a pop up window.

I have the code working outside a update panel but inside it doesn't seem to work?

Any ideas please.

Here's the code that should be called by the image command.

protected void imgOverview_Command(object sender, CommandEventArgs e)
   {
       Session.Remove("cdID");
       Session.Add("cdID", e.CommandArgument.ToString());
       ClientScript.RegisterClientScriptBlock(typeof(Page), "smallWindows", "<script>window.open('confirmCD.aspx', 'PopupPage', 'height=450,width=500,scrollbars=yes,resizable=yes');</script>");
   }

Thanks

what is the updatemode of your updatepanel?

You should be able to find the ID of your image in the codebehind. If you would change the url of the ImageButton another image should be displayed.

I think I found the problem. I had triggers on my command buttons but not triggers on the image button so it wasn't posting back. once I put in postback triggers it worked

hi i want convert this code to javascript

dim x as integer =25
For i as integer = 0 To 10
If x And ((2 ^ i)) Then
.....

End If
Next

Re: convert vb to javascript

Christian Graus7-Jul-08 4:08

Christian Graus

7-Jul-08 4:08

javascript is not strongly typed, so

var x = 25;

var i = 0;

for (i = 0 to 10)
if (x & (2^i)) // I THINK. && will just check if x is 'true' and 2^i is 'true', not a check for bitwise comparison
{

}

Except, are you wanting a bitwise AND ? Does And do that in VB ?

Hello,
i made and web application that i must use Ajax Accordion. The idea is accordion and his panes to be dynamically created. Actually the data (header and content)for accordion will come from text files. I developed the part that load data from text files but how to bind(?) this data to accordion? I look over and didn't find some solution that is work for me [Frown]
The problem for me actually is in creation in accordion and his panes.

Thanks!!!

I finally get it Smile | :)

and it was so simple ... as usual Big Grin | :-D

OK. I've got accordion control added in designer and two datatables with two columns (one for title and one for link). The idea is in accordion to have two panes (for each datatable) and in content to have "title" column whith link. So here is the code that work for me:

        // create first pane
        AccordionPane ap1 = new AccordionPane();

        //Add header container and define label on it
        ap1.HeaderContainer.Controls.Add(new LiteralControl("UnRead Items"));

        // define css for header (if you have)
        ap1.HeaderCssClass = "header1";

        // create and fill content
        for (int a = 0; a < myDataTable.Rows.Count; a++)
        {
        // for each row in first datatable add in content firs column text(title) and second  
        //column value is hyper link
            ap1.ContentContainer.Controls.Add(new LiteralControl("<a href=" + myDataTable.Rows[a] [1].ToString() + ">" + myDataTable.Rows[a][0].ToString() + "</a>" + "<br>"));

       // define css for container (if you have)        
            ap1.ContentContainer.CssClass = "container";

       // add pane to accordion
            acc1.Panes.Add(ap1);
        }

// the same situation is and for second pane
        AccordionPane ap2 = new AccordionPane();
        ap2.HeaderContainer.Controls.Add(new LiteralControl("Archived Items"));
        ap2.HeaderCssClass = "header1";

        for (int z = 0; z < myDataTable1.Rows.Count; z++)
        {
            ap2.ContentContainer.Controls.Add(new LiteralControl("<a href=" + myDataTable1.Rows[z][1].ToString() + ">" + myDataTable1.Rows[z][0].ToString() + "</a>" + "<br>"));
            ap2.ContentContainer.CssClass = "container";
            acc1.Panes.Add(ap2);
        }
</br></br>

So the result looks like this (depending on css):

how we can set and unset or destory sesstion?

Buy a book on ASP.NET and read it. This is such an entry level question that even tho I will answer it, it's clear you have a lot to learn.

Session["MyKey"] = "value"; // can be any type
string s = (string)Session["MyKey"];
Session["MyKey"] = null;

I would put the keys into a class, so that you're not always typing them, the compiler will not find typos in there. Also, I'd add methods to a base page class that safely check if a session object is null and return a bool if it is, just like the tryparse methods on classes like string.

Server.MapPath("/") gives the root path for that server.
