Hi All
Java Script Error...
I am using AJAX and i am getting problem at:
//Add new states list to the state combo box.
for (var count = 0; count < stateNodes.length; count++)
{
textValue = GetInnerText(stateNodes[count]);
alert(textValue);
optionItem = new Option(textValue,textValue, false, false);
cmbstate.options[cmbstate.length] = optionItem;
}
it is not loading cmbstate from return response. Please note textvalue is coming and moreover cmbstate is correct name.......
Any thoughts...

Standard question #2:
What error message do you get?
What is "cmbstate" the correct name for? Do you create that variable somewhere, or are you just trying to access an element as if it was a variable?

Hi Folks -
Here is what I want to do. I'm hoping someone out there knows what the best way to achieve my desired results is.
TOOLS
Development platform is of course Visual Studio 2005 on XP Pro (sometimes Vista RC1) with dot net 2.0.
MY PROBLEM
I have created many user controls that are essentially report summary panels that display various types of info and or controls in a table - the actual functions are not important. Each user control has many common UI elements - they are all in a table, they all have a title header, they all have a link in the header to show or hide the results and a link to a form to create or edit a record. They all have properties and methods that set the title, respond to the links etc. Since they are all so similar it seems obvious that a more OOP approach is warranted but I'm at a loss as to how best to proceed.
DESIRED SOLUTION DIRECTION
With the concept of the master site page and replaceable content pages in mind is there a way to build a master user control that captures the common elements and then develop user controls for the specific content that inherit the common elements from the master control? As I evolve the common elements I want all the user controls to inherit the UI elements from the base control as well as the common properties and methods in the base code behind file. The master page concept is such an elegant solution at the page (.aspx) level it only seems logical there should be a similar solution at the user control (.ascx) level.
I've spent the last 2 days reading various MSDN articles and USENET listings and none of the approaches I've read so far seem to address my requirements. The closest seems to indicate that I need to create a class that will write the common HTML out to a placeholder on my control but that bypasses the desired goal of using the visual designer.
I hope one of you gurus out there has a really slick and simple solution to my problem.
Thanks in advance,
Michael

You can't use AJAX to load an image.
If you need a call to the server to find out the name of the image, you can use AJAX, but the loading of the image itself is done by the browser.
If you don't need a call to the server to find out the name of the image, you don't need AJAX at all.

perhaps this be your answer :
var img=new Image();
MyImage.src="newImage.jpg";
function Change()
{
document.images[0].src=MyImage.src;
}
now you can call Change function to load new Image without postback.

I'm building an application for students to answer test questions, and later get feedback on their learning. I have an SQL database holding the questions and their associated multiple choice answers. Answers to each question have an integer ID number, starting at one. The correct answer is always ID 1.
I want to be able to display the multiple choices in a ListBox, in a random order. At the moment I have an SQL call to the database to extract the appropriate answers, ordered by NewID (random). These fill a DataSet and this is then used to fill a Hashtable of the AnswerID and Answer Text pairs.
While the items are placed into the Hashtable in the random order that they were retrieved from the database, they seem to reorder themselves numerically once in the Hashtable. Therefore when my ListBox (showing only the answer text) binds to the Hashtable it always shows the correct answer in the last slot in the list.
How can I ensure that the items in either the Hashtable or the ListBox are randomized?
Many thanks,
Alice

The data in a hash table is stored according to the hash code of the keys, so if you have the same keys, you will always get the same order. If you want to maintain the order that the data was fetched in, don't use a hash table.
I would not put the correct answer as always having id 1. If someone views the source of the page, it wouldn't be that hard to figure out the pattern.

Hi,
I'm trying to use callback function to send a randon number to the client. My code works on a normal page, but not on a page with Masterpage.
My JavaScript is:
//To call the function in the Server
function GetNumber() {
UseCallBack();
}
// To retrive the value from the server to display it in the TextBox1
function GetRandomNumberFromServer(arg, context) {
document.cforms[0].TextBox1.value = arg;
}
So is there anything I should change?
Thanks,
Si Jia

What do you mean by it's not working on the web page using MasterPage? Is that the problem of accessing the textbox element? If so, you may need to view source the web page to have an idea about the id of the textbox at the client side.

Cool. Thank you so much
After I View the source code during the runtime, I find the ID of the textbox.
The ID of the textbox is "ctl00$ContentPlaceHolder1$TextBox1" The name of the textbox is just TextBox1 and the "ct100" I don't know what it means but it's just there.
Just in case someone has the same problem with me.
Cheers,

The ctl00 is the ID of the master page instance at runtime, you can set the Trace="true" in the Page directive, browse the web page and look at the control tree section that may give you some information.

hello all,
i have the following problem:
in a page i render the html output of a calendar control manually by cal.render(writer)
in first second it look ok but unfortunately there is no functionality rendered to the output. That means no links, no script code, ...
Is there a trick to render the needed java script code to the resulting HTML?
thanks, bernd

hmm, you may think this does not make sense, but i try to create some aspx stuff by ironPython and so i haven't not a real aspx enviroment. That means i haven't a page_load event or something like that. Does someone of you know some details about the rendering process of webcontrolls in common? For example which method renders script code, who call's this method and when is it called?
i'll be happy about any suggestion. Thanks
Bernd

Hi there,
You may want to look at the Page Object Model[^] and Page Life Cycle[^] that may give you some ideas. Basically, the common script which can be reused in the web page will be emitted by the Page instance, and the control-specific script can be rendered by the control itself. Which script are you talking about?

hey minhpc_bk, nice to read you!
i.E the function '__doPostBack' and all call's to that function are missing. actualy no links aren't rendered. you can take a look at www.gmc.li. First i'll check out your posted link's.
thanks, bernd

stop - the function will be rendered!! In my control isn't set the Property 'Page' which can explain a lot 
-- modified at 16:51 Monday 2nd October, 2006
false alarm  the script was rendered by another aspx control. still with no idea. isn't there a property 'enableClientScripting' ore something else? Please take a look at the code[^] here, maybe one of you can see my big mistake.

To work around the error of not being placed outside the server form element, you'll have two options here:
+ Extend the Page class, override the VerifyRenderingInServerForm method and leave it empty.
+ Extend the Calendar control and override the Render method to skip the calling to the VerifyRenderingInServerForm of the Page instance.
Below is the sample code for the first option which IMO is much simpler:
public class ExPage : Page
{
public override void VerifyRenderingInServerForm(Control control)
{
}
}
