Hi Muralidharan,

Try the following code snippets.
ASPX:

<telerik:RadComboBox ID="RadComboBox1" runat="server">
    <Items>
        <telerik:RadComboBoxItem runat="server" Text="Text1" Value="Value1" />
        <telerik:RadComboBoxItem runat="server" Text="Text2" Value="Value2" />
        <telerik:RadComboBoxItem runat="server" Text="Text3" Value="Value3" />
    </Items>
</telerik:RadComboBox>
<input id="Button1" type="button" value="Get Value" onclick="button_click();"/>

JavaScript:

<script type="text/javascript">

function button_click()

{

var combo = $find("<%= RadComboBox1.ClientID %>");

var value = combo.get_value(); //get the value

alert(value);

}

</script>

Thanks,
Shinu.

Lets say I want to iterate over the radcomboboxitems, and remove a specific one based on it's value (not it's text).

Something like this:

 

 

 

 

function RemoveItem(value) {

 

 

 

    var combo = $find("<%= cbDefaultCurrency.ClientID %>");

 

 

 

    var comboItems = combo.get_items();

 

 

 

    for (i = 0; i < combo.get_items().get_count(); i++) {

 

 

 

        var comboItem = comboItems[i];

 

 

 

        if (comboItem.Value == value) { 
        //I've tried many varients on the line above and they are all not liked. .get_value() etc...

 

            combo.trackChanges();

            combo.get_items().remove(comboItem);

            combo.commitChanges();

 

 

            break;

 

        }

    }

}

 

 

I'm already able to add items smoothly using this, I just want to be able to remove as well.

 

 

 

function AddNewItem(name, value) {

 

 

 

    var combo = $find("<%= cbDefaultCurrency.ClientID %>");

 

 

 

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

 

    comboItem.set_text(name);

    comboItem.set_value(value);

    combo.trackChanges();

    combo.get_items().add(comboItem);

 

 

    if (combo.get_items().get_count() == 1) {

 

        comboItem.select();

        comboItem.scrollIntoView();

    }

    combo.commitChanges();

}

Hello,

Try the following.
JS:

function OnClientClick()
 {
    var comboBox = $find("<%=RadComboBox1.ClientID %>");
    var count = comboBox.get_items().get_count();
     for (var i = 0; i < count; i++)
     {
         var item = comboBox.get_items().getItem(i);
         var val = item.get_value();
         if (val == "s")
           {
             comboBox.get_items().remove(item);
           }
     }
  }

Thanks,
Princy.
