ClientEvents-OnValueChanged With RadInputManager

[Ali]

hi,

How can I replace RadNumericTextbox (attached with client event OnValueChanged) with RadInputManager and Asp:Textbox? As InputManager only exposes "OnBlur, OnError, OnFocus and OnKeyPress" events.

Thanks

Ali

Hi Ali,



You can use onchange event handler. This event is fired when the contents are committed. For example, on a text box, this event is not fired while the user is typing, but rather when the user commits the change by leaving the text box that has focus. In addition, this event is executed before the code specified by onblur when the control is also losing the focus.

The following example demonstrates how to execute some JavaScript code when a user changes the content of an TextBox control:

    <div>
        <script type="text/javascript">
            function change() {
                var manager = $find("<%= RadInputManager1.ClientID %>");
                var numericInput = manager.get_targetInput("<%= TextBox1.ClientID %>");
                numericInput.clear();
            }
        </script>
        <telerik:RadInputManager ID="RadInputManager1" runat="server">
            <telerik:NumericTextBoxSetting EmptyMessage="type here...">
                <TargetControls>
                    <telerik:TargetInput ControlID="TextBox1" />
                </TargetControls>
            </telerik:NumericTextBoxSetting>
        </telerik:RadInputManager>

        <asp:TextBox onchange="change();" ID="TextBox1" runat="server">
        </asp:TextBox>
    </div>

Actually I need two arguments (Source and EventArgs) in the ValueChanged event. I can pass Source but EventArgs is not possible in suggested solution.
I am already taking decicion on EventArgs and I've around 30+ input controls on a single page. So is there any other way to hook ValueChanged event with Source and EventArgs parameters?

Thanks

Hello Ali,

There is no way to get the old value at the moment. This is certainly a limitation of our RadInputManager control and we will be working on solving the problem with the next release. We apologize for the inconvenience this might be causing you.

Having any other questions, please feel free to contact us.

I can't download sample application.  It says the it doesn't exist or the location has changed.  Could you repost the application?

Thanks.
