    Okay here goes.
    I can't seem to obtain a ref to any of my input settings on the client via the input manager.

    Here's what I'm seeing in my intellisense

    -        $find('RadInputManager').get_inputSettings()    {...}    Object
    •         [Methods]        
    •         RadInputManager_NumericSettings    null    Variant
    •         RadInputManager_TextSettings    null    Variant

    Here's my markup:
         <%-- The following TextBox is required by the InputManager --%>  
        <asp:TextBox ID="TextBox1" runat="server" Visible="false" />  
             
        <telerik:RadInputManager ID="RadInputManager" runat="server" Skin="Vista"> 
            <telerik:NumericTextBoxSetting BehaviorID="NumericSettings" InitializeOnClient="true" Type="Number" DecimalDigits="1" GroupSizes="3" GroupSeparator="," PositivePattern="n" NegativePattern="-n">  
                <TargetControls> 
                    <telerik:TargetInput ControlID="TextBox1" /> 
                </TargetControls> 
            </telerik:NumericTextBoxSetting> 
            <telerik:TextBoxSetting BehaviorID="TextSettings" InitializeOnClient="true"  > 
                <TargetControls> 
                    <telerik:TargetInput ControlID="TextBox1" /> 
                </TargetControls> 
            </telerik:TextBoxSetting> 
        </telerik:RadInputManager> 

    Ideally I'd like to be able to do this
                    var numericSettings = $find('RadInputManager').get_inputSettings('NumericSettings'); 
                    Array.forEach(elements, function(element) { 
                        numericSettings.addTargetInput(element.id); 
                    });

    I've since also tried the following to see if using this technique would grant me access to the input settings on the client but the settings remain null. I assume both the techniques I've presented here pretty much evaluate to the same thing.
        <script runat="server">   
              
                void Page_Init(object sender, EventArgs e){  
                    RadInputManager input = new RadInputManager();  
                    input.ID = "RadInputManager1";  
                    input.Skin="Vista";  
                    NumericTextBoxSetting numSet = new NumericTextBoxSetting();  
                    numSet.BehaviorID = "NumericSettings";  
                    input.InputSettings.Add(numSet);  
                    input.InputSettings[0].TargetControls.Add(new TargetInput(TextBox1.UniqueID, true));  
                    this.Page.Form.Controls.Add(input);  
                }  
           
    </script>   


    Cheers.

    My problem was that I was setting the Visibility of my text box to false!
    If I want to hide the text box just to use a dummy control for the input manager, I should be setting its display style to none.

    Thanks.

    Hey, While I'm here I may as well put this one out there.

    If I have the text box formatting the value for me, how do i get the raw value out of it excluding the formatting?
    If a user types 1000, the text box formats it as 1,000. For calculations I'd like the value without commas. If there's a way to do that using jquery that would be helpful.

    $('input.RadInputMgr_Vista', selectedItems[i].get_element()).val(); This returns the value with formatting.

    thanks

    Hello Matt,

    If you use the RadInputManager API and the get_value() method, you will get the real numeric value, instead of the formatted one that you are seeing in the textbox.

    var im = $find("<%= RadInputManager1.ClientID %>");
    var v = im.get_targetInput("<%= TextBox1.ClientID %>").get_value();


    Kind regards,

    Thanks a lot, Dimo.

    There's still another issue I've been meaning to mention.
    So what I'm doing, as I tried to previously illustrate, is grabbing a bunch if input items using jquery and then loading those into a radInputManager. All these inputs are rendered in a radGrid using a column renderer all on the client-side.
    A numeric input gets a numeric class so I can therefore grab all my numeric inputs using the line

    var elements = $('input.numeric'); 

    I then generate a unique Id for each of the inputs before loading them into the numeric settings of my input manager

                var numericSettings = $find('RadInputManager').get_inputSettings('NumericSettings'); 
                Array.forEach(elements, function(element) { 
                    numericSettings.addTargetInput(element.id); 
                });   

    After I load my elements into the manager, the class is completely overwritten by RadInputMgr_Vista. Is this behaviour by design? I'd rather it append to any existing class so I don't lose the ability to grab all my numeric inputs.

    I was thinking, immediately after loading my inputs into the manager, to do something like this to re-add my desired class
    $("input.RadInputMgr_Vista").addClass("numeric"); //since adding controls to the manager collection overwrites existing classes, readding them here. 

     But that won't help me if after dealing with my numeric inputs I have to do the same work on my ascii ones.
     //get all ascii data format text boxes and convert them into text 
                elements = $('input.ascii'); 
              
                var textSettings = $find('RadInputManager').get_inputSettings('TextSettings'); 
                Array.forEach(elements, function(element) { 
                    textSettings.addTargetInput(element.id); 
                });                 
                $("input.RadInputMgr_Vista").addClass("ascii"); //since adding controls to the manager collection overwrites existing classes, readding them here. 

    At the end there, all of my RadInputMgr_Vista inputs, including my numeric ones, will also get the ascii class...

    Any thoughts?

    Thanks.

    Hello Matt,

    Yes, RadInputManager currently overwrites the existing CSS classes of textboxes. We may change that in the future. Currently you have two options to grab all RadInputManager textboxes:

    1) add your custom CSS class to the InputManager settings, so that you can get all textboxes with jQuery:

    <telerik:NumericTextBoxSetting BehaviorID="NumericTextBoxSetting1"
            InitializeOnClient="true" EnabledCssClass="numeric">

    (this will append the CSS class to the control's default ones)


    2) Iterate through all textboxes by using the InputManager's API, e.g. :

    input_manager_instance.get_numericTextBoxSettings()[0].get_targetControlIDs()

    Grrrr!

    Why does the RadInputManager even need a "dummy control"? And, why don't the docs mention this?

    Thanks for the thread, towps.

    Hello,

    Indeed, this limitation exists by design. We will research for ways to remove it in future versions and will mention it in the documentation. Thanks.

    Dimo,

    Given your example here:  how can I toggle on and off an entire inputManager?  I am showing/hiding textboxes based on user input, but I want to be able to validate all shown controls on submit.  So if a user changes a dropdown I need the new boxes to be validated, if they change again then they will be hidden and not validated.

    It seems to make sense to me to just break them all into separate inputmanagers and then enable/disable them. But can this be done on the client?
