How can I send the whole asyncuploadcontrol to a webmethod for handling?

My implementation prevents me from using the traditional OnFileUploaded event since there are several instances of this control and each needs to be tied to a ticketID that is contained in a hidden field. I was able to get a reference to the uploader object that is relevant to the button that fired the event like this:

$(".SubmitFiles").click(function () {

var uplodrID = $(this).closest(".AddAttachment").find(".Uploader").attr("ID");

var upldrObj = $find(uplodrID); //this is the telerik asyncupload control

});

At least, I'm pretty sure it is because I can see all of the relevent settings and such inside of it during debug. Now, what I want to do is send this control into a webmethod in the page codebehind so that I can interate through all the files and send them to a database. I tried to do so like this:

PageMethods.ProcessUpload(upldrObj);

And of course I enabled pagemethods in the ScriptManager. What is happening is ...well nothing. The page doesn't throw and error, but its also not showing that it is actually getting through to the webmethod. I set the webmethod to throw an exception if it ever got that far, but it never does. When I step through debug, the debug finishes before it ever gets to the webmethod:

[WebMethod()]

public static void ProcessUpload(RadAsyncUpload upld)

{

throw new Exception("Stub");

}

Can anyone help? I'm sure I'm missing something minor

Filling Combobox on client side doesn't work

Dear team,

I have nearly tried everything to manage to fill a combobox with java script. I got a component where I retrieve 2 strings which I want to show in the combobox.
The problem is, that I always get a null value for cmbSource.

Any ideas?

// edit: I also tried it with a listbox. Same problem.

cmbSource = $get('< %= listBoxSource.ClientID %>');

always returns null...

<script type="text/javascript">

$(document).ready(function () {

var cmbSource = $find('<%= comboboxSource.ClientID %>');

init(cmbSource); // function to fill in the values

});

</script>

// in a table, embedded in a asp Panel

<telerik:RadComboBox ID="comboboxSource" runat="server" Width="35%" />

// in java script

function init(comboboxSource) {

var comboItem = new Telerik.Web.UI.RadComboBoxItem();

comboItem.set_text("test");

comboboxSource.get_items().add(comboItem);

comboboxSource.commitChanges();

}

Radgrid client side data binding

Hi,

I'm using rad grid with client side data binding and so far everything works fine except for issues with paging. Paging works fine but there is a problem with Page size. With the page size drop down menu jumping from 10 to 20 or 20 to 50 data is not displaying correctly once the page size exceeds the number set in the pageSize property. I attached a screen shot to give you an idea. The page size property is set to 10 and my data grid is displaying 20 results. You can see where the first 10 displays correctly but the second 10 does not. If I set the page size property to 20 then everything is fine. I tried setting the page size property(tableView.set_pageSize(20)) on the client side but that didn't work. Any suggestions? I'll really appreciate it.

Thanks,
Ron

Cascading Comboboxes

Hi Guys, I have been playing with this and can't figure it out.

The setup. I have two comboboxes. The first is a list of countries. The second is a cascading box and displays States, dependent on the country selected in the first combo box. Here is how I want it to work.

1. When the page loads, the Countries Combobox (RadCombobox1) is visible and lists the countries. The States Combobox (RadCombobox2) is not visible.

2. After the user selects a country, it fires the OnClientSelectedIndexChanged="fired" javascript function which in turn fires the RadComboBox2 requestItems event passing the countryID value.

3. The RadComboBox2 requestItems event then populates the state list for Australia (Country ID 1), Canada (Country ID 7) or the USA (Country ID 45), or nothing if it is any other country. Then I want the RadComboBox2 to be visible and dropped down if the country is Australia, Canada, or the USA, and if it is not then I want it to be visible but looking like a text box (RadComboBox2.ShowToggleImage = False

,RadComboBox2.ShowDropDownOnTextboxClick = False) so that they can type in their state.

4. All seems to work ok, except that the RadComboBox2.ShowToggleImage = False and RadComboBox2.ShowDropDownOnTextboxClick = False does not work unless there is a postback (such as clicking the button).

5.If I use RadAjaxManager (on RadCombobox1 to update RadCombobox2) then it doesn't work because the requiredfieldvalidator on name won't allow the postback unless a the name field is filled out. This is a striped down version, in real life there will be many textbox inputs above and below the country and state comboboxes, and they will have requiredfieldvalidators. Is there a way of turning these validators off for the RadAjaxManager postback?

6. On another note, was there a simpler way of hiding RadComboBox2 when the page was first loaded instead of using a literal to insert javascript. HideCombo does not work. If I change the visibility then it does not render, so that doesn't work. If I use set_visibile(false) in the pageload()then it disappears on postback.

Many thanks in advance.
