Using CSS and html need the below format like category and sub-categories (Definetly it should be like expanding and collapsing functionality). Could anyone please give me some ideas on aspx side as well as code-behind. That would be great.

I'm getting this error after upgrading my app to the latest version.  What am I missing?

"Unable to get property '_events' of undefined or null reference"

"Uncaught TypeError: Cannot read properties of undefined (reading '_events')"

The RadNumericTextBox is rounding incorrectly after a postback.

I am currently using 5 decimal places with the value of

0.00481487920209807

When the page loads it displays correctly

After I click the Postback button the display value changes

<div class="form-row">
            <asp:Button ID="btnCausePostback" Text="Postback" runat="server" OnClick="btnCausePostback_Click" />
            <telerik:RadNumericTextBox runat="server" ID="txtUnitCost" NumberFormat-DecimalDigits="5" Value="0.00481487920209807" />​
        </div>

protected void btnCausePostback_Click(object sender, EventArgs e)
        {

        }

I am not sure what the round function is doing in this scenario?

I do have a work around which is setting

NumberFormat-AllowRounding="false"

Hello,

I'm using a RadScheduler and I have set it to display the AdvanceEditForm on click on an appointment.

I also have a RadToolTipManager to have a custom tooltip when the mouse pass over an appointment.

The problem I have is that :

    - if I click on the appointment before the RadToolTipManager begin to show the tooltip

or

    - if I move on another appointment after clicking on one and before the AdvanceEditForm appears

the clientappointmentclick event is cancelled by the tooltip ...

How can I do to avoid this problem ?

Best regards,

I made a sliding panal as your example but with a little deferent that the panel in (OCX) user Control , it work fine but the problem is that it start in an open position , i want it to start closed and be opened when i click the button . my code is :

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

       <%-- <script src="scripts.js" type="text/javascript"></script>--%>
 <%-- /**/--%>

        <script type="text/javascript">
            Sys.Application.add_load(function() {

                demo.rightPanel = $get('<%=RadPanelBar2.ClientID %>');
              <%--  demo.rightButton = $get('<%=rightbutton.ClientID %>');--%>
                demo.rightButton = document.getElementById("rightbutton");

              <%--  demo.rightButton = $find("<%=rightbutton.ClientID %>");--%>

                demo.initialize();
            });
        </script>
    </telerik:RadScriptBlock>

<div class="right-pane">
            <input type="image" id="rightbutton" class="button" src="../images/ElmosamenIcon.png" />

   <%--  <telerik:RadButton RenderMode="Lightweight" ID="rightbutton" runat="server" ButtonType="ToggleButton" ToggleType="CheckBox"

                        </ToggleStates>
                    </telerik:RadButton>--%>

            <div class="sliding-pane">
            <telerik:RadPanelBar RenderMode="Lightweight" ID="RadPanelBar2" runat="server"  Width="200px"  skin="BlackMetroTouch" Height="605px"  ExpandMode="FullExpandedItem"

            </DataBindings>
        </telerik:RadPanelBar>


            </div>
        </div>

with  a java script code as

(function () {
    var demo = window.demo = window.demo || {};



    demo.initialize = function () {


        var rightPanel = demo.rightPanel;
        var rightButton = demo.rightButton;

        if (rightPanel) {
            SetUpAnimation(rightButton, Telerik.Web.UI.jSlideDirection.left, rightPanel);
        }
    }

    window.SetUpAnimation = function (button, direction, element) {
        element.style.position = "relative";

        var expanded = true;

        var expandAnimation = new Telerik.Web.UI.AnimationSettings({});
        var collapseAnimation = new Telerik.Web.UI.AnimationSettings({});

        var slide = new Telerik.Web.UI.jSlide(element, expandAnimation, collapseAnimation, false);

        slide.initialize();

        slide.set_direction(direction);

        button.onclick = function () {
            element.parentNode.style.visibility = "visible";
            element.parentNode.style.display = "block";
            if (!expanded) {
                slide.expand();
            }
            else {
                slide.collapse();
            }
            expanded = !expanded;
            return false;
        }
    };
}())

I also try to use a Rad button with type  ToggleButton  to change the button image when i click the button , it work well but the problem it is appear in the left side of the sliding panel
