Page Method instead of Web Service

[SamVanity]

Is there a way we can use page method instead of web service? If so, what are the steps involved to make this happen?

Hi Sam Van,

I have tried using PageMethods in order to populate RadComboBox. See the example.

ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server" ToolTip="Please enter your title" Skin="WebBlue" EnableLoadOnDemand="True" AutoPostBack="True" >
</telerik:RadComboBox>
<input id="Button1" onclick="LoadItems();" type="button" value="GetItems" />

JavaScript:

<script type="text/javascript">
function LoadItems()
{
    PageMethods.GetItems(onGetComplete);
}
function onGetComplete(result)
{
    var data = result;
    srcArray = new Array(10);
    srcArray = data;
    for(var i=0;i<data.length;i++)
    {
        AddNewItem(data[i]);
    }
}
function AddNewItem(data)
{
    var combo = $find("RadComboBox1");
    combo.set_closeDropDownOnBlur(false);
    var intextput = data;
    var comboItem = new Telerik.Web.UI.RadComboBoxItem();
    comboItem.set_text(intextput);
    combo.trackChanges();
    combo.get_items().add(comboItem);
    comboItem.select();
    combo.commitChanges();
    comboItem.scrollIntoView();
}
</script>

C#:

using System.Web.Services;
public partial class PageMethod : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    [WebMethod]
    public static string[] GetItems()
    {
        string[] items = { "Item1", "Item2", "Item3" };
        return items;
    }
}

Thanks,
Princy.

thanks for your reply, but I was referring to the feature that when you type something into the box, the box requests a pagemethod instead of a web service.

But your code is certainly useful (client side API). I am thinking maybe we can handle the OnClientItemsRequesting event: issue set_cancel(true) + call the page method in this handler. Then use your code to add items to the combo box...
