Hello Eva,

Are the input controls 'inputified' by the RadInputManager immediately available on the page on initial load or displayed afterwards? Note that we discovered a bug with the control in the second scenario which should be addressed for the Q3 2008 SP2 release, expected by the end of the next week.

In the meantime you can download the latest internal trial build of RadControls for ASP.NET AJAX from this section after logging from your Telerik account. Please migrate to it following the instructions from here and let me know how it goes.

Thanks, - Love the new Inputmanager

Hey folks.
I just ran into this same error.
It's happening on a post back when using the radInputManager. When I comment out the crus of the inputManager markup, the error does not occur.

We're doing an explicit postback using __dopostback.
When we switch the __doPostBack to window.location.reload() there was no error. It looks like the input manager isn't a fan of postbacks.

It's breaking here

beforeSubmit:function(com){

var ids=com.get_targetControlIDs(); //breaks here!

for(i=0;i<ids.length;i++){

com.get_targetInput(ids[i])._beforeSubmit();

}

My inputManager markup is quite simple.

      <%-- The following TextBox is required by the InputManager --%>
    <asp:TextBox ID="dummy1" runat="server"  style="display:none" />
    <asp:TextBox ID="dummy2" runat="server"  style="display:none" />
    <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="dummy1" />
            </TargetControls>
        </telerik:NumericTextBoxSetting>
        <telerik:TextBoxSetting BehaviorID="TextSettings" InitializeOnClient="true"  >
            <TargetControls>
                <telerik:TargetInput ControlID="dummy2" />
            </TargetControls>
        </telerik:TextBoxSetting>
    </telerik:RadInputManager>

As is the code to load it with input controls

            var im = $find("<%= RadInputManager.ClientID %>");
            var numericSetting = im.get_inputSettings("NumericSettings");

            //get all numeric data format text boxes and convert them into numeric only
            var elements = $('input.numeric');
            generateInputIds(elements);
            var numericSettings = $find('RadInputManager').get_inputSettings('NumericSettings');
            Array.forEach(elements, function(element) {
                numericSettings.addTargetInput(element.id);
            });

            //get all ascii data format text boxes and convert them into text
            elements = $('input.ascii');
            generateInputIds(elements);
            var textSettings = $find('RadInputManager').get_inputSettings('TextSettings');
            Array.forEach(elements, function(element) {
                textSettings.addTargetInput(element.id);
            });

Any help would be great. Thanks.

Hi,

The input manager looks like a great control set. I am having issues when dynamically adding textboxes requiring formatting (added via Anthem callbacks. The information on the forums have helped overcome a number of issues so thanks for that!

I was just wondering why when adding input ids to using the addTargetInput on the client side is there a need to
run a function like generateInputIds(elements);? What is in here exactly and why would one need it?

My problem is where I am dynamically adding textboxes to the page (via Anthem call back). Once the callback completes, the textboxes are on the page and I then use client side API to add the target controls to the input manager/numeric settings. But I tend to get inconsistent results: some textboxes abide by the settings while others don't. On subsequent callbacks the behaviour switches round. As soon as I run generateInputIds, mine looks like this (wild guess here)

function generateInputIds(elements) {
    for (var i = 0; i < elements.length; i++) {
        elements[i].id = elements[i].id + '$'+ i;
    }
}

then the inconsistencies dissapears. Changing the ids is going to cause some problems when I finally submit my page to the server since the ids on the client are now different to the server?

I am using dll 2009.2.701.35.

Insight to this problem will be highly appreciated.

Thanks

Hello Richard,

I am not sure I understand your scenario completely. Are you adding InputSettings on the client? If this is the case you should know that  this is generally not supported. I can suggest you to check our examples to get a better idea of what can be done with the RadInputManager control.
