Hi,
Can any body tell me how to use checkboxlist in ASP.NET MVC 2.0
Thanks for help
|
|
|
|
|
An ASP.NET CheckBoxList is rendered as a table an input element and label in the cells so if you want to replicate it
<table>
<% foreach(item in ViewData["MyList"]) { %>
<tr><td> <% Html.CheckBox(...) %> <% Html.Label(...) %> </td></tr>
<% } %>
</table>

I have a form with a data bound accordion on it. It's being data bound the standard way:
Accordion1.DataSource = dt.DefaultView;
Accordion1.DataBind();
...
The entire form works perfectly at this stage. There is a major problem when I add a row to the datatable and rebind it.
DataRow newDr = dt.NewRow();
...
dt.Rows.Add(newDr);
Accordion1.DataSource = dt.DefaultView;
Accordion1.DataBind();
At this point, the accordion rebinds, and it displays correctly on the page. But there is a problem. When I do any action on the page, the code behind doesn't see the new row. In fact, all the values from the accordion are null or string.Empty. I then checked view source on the browser, and it doesn't show anything for the new row. It seems like it doesn't exist, but it is there on the screen.
As usual, I am under an extreme deadline, and ANY suggestions would be greatly appreciated. I'm sure it's something very stupid that I am missing.
Thanks

just add proper data to the newly added row.
Like,
newDr["name"]="Jinal Desai"
Then might be your problem solved.

Thanks for your reply, but I am doing that. In my original message, I replaced the assignment portion of the code with "..." to save space and to not take away from the real issue, which is that the control does not maintain state across postbacks when the datasource has been changed.
I put a ticket into Microsoft, and they confirmed my findings. The problem is that they created the controls and put them out to open source, so they will not fix the problem.

Hi People,
I have a problem with AJAX enabled Listbox. The thing is, my listbox is generated dynamically at runtime. After selecting few items in it, if I do anything which cause partial postback (like clicking a button), the listbox index is reset to 0.
This is obvious because on each partial postback, the listbox is regenarating again.
I have done the coding for reseting the selected fields but it is not scrolling to the selected items automatically. User then has to scroll down manually to see if anything is selected.
Is there anyway I can scroll up/down into javascript for Listboxes. ScrollTo property only works for "window" element not "select"..... 
Thanks for any help.
Regards,
Anand Desai

It works with div's and grid too. I have done that in my project. Try setting the scroll's in the Ajax End request handler using javascript. It should work.

Hi,
I am using ajax for my existing VS 2005 Web application.
I have applied all the necessary modification to Web.config.
My application is working fine when we opening the page.
We are also providing Back and Forward links to user ( similar to browser Back and Forward for history) .
When user visits 2nd page, we are saving the generated HTML of first page into a java script variable .like below.
var html = document.frames[“MyFrame”].document.documentElement.outerHTML;
when user clicks on Back link we displaying the page from stored java script variable. Like below
var doc = document.frames[“MyFrame”].document.open();
doc.write(html);
Here we are getting error saying “Microsoft JScript runtime error: 'Sys' is undefined”.
Sys.WebForms.PageRequestManager._initialize('ctl00', document.getElementById('Form1'));
Thanks,
Salmon

I'm sorry but this is horrendously stupid idea. This falls under the just because you can doesn't me you should rule.
Just navigate back to the page in question and let the rendering engine do what it is meant to. There are plenty of examples of using the back an forward buttons with Ajax

It is in Asp.Net only...
When u write code in ASP.net, it means you have to choose the language you prefer to code either vb.net or C# etc..
the code which i have send is used in asp.net application only...
and if u are using the C# as code behind then.. convert this piece of code into c# as we have many online converters...
paste the code they will give converted format in C#...

<A NAME="Anyname"></A>Your Text
<A HREF="#Anyname">Click Here</A>
The above page link works fine on Firefox and doesn't work on IE.
On IE something like this works -
<A NAME="Anyname">Your Text</A>
<A HREF="#Anyname">Click Here</A>
but i don't want "Your Text" to appear as same font as link i.e. A tag and that is the reason i want to use
<A NAME="Anyname"></A>Your Text
Any ideas??
Andyyy

I have been using the above method only in my applications. It works perfectly in Internet Explorer as well as Firefox. Please check well whether you are missing something.
And also what version of IE are you using?

Then use CSS, as in Cascading Style Sheets, to set the style.
