How to prevent UI elements from improperly rendering on page load on mobile website?

I am creating a mobile website using radcomboboxes inside of update controls that are set to autopostback = true. All of the controls work except on the page's initial load the UI elements are enlarged and look more like buttons. They are still able to be selected and after the controls postback the elements still do not go back to a normal size. Only after a postback from another control do the UI elements shrink down to a normal size.

I have tested the radcombobox with checkboxes enabled outside of the update panel and this behavior does not change. I have a master page that contains jQuery files located in the header, and when I remove one of the js files, the problem disappears with the UI elements disappearing. Can anyone help me figure out what is preventing the UI elements from rendering properly?

On Load:

After postback:

RadGrid Master-Detail with Insert on Detail Table.. How to?

Hi,

Long time Webforms developer here, but just starting out with Telerik Rad controls.

I can't for the life of me figure out how to get the "Insert Record" button to show up on my Grid that has a Master-Detail relationship.

I looked at the code sample and can't figure out what I am missing.

Any help you could provide would be appreciated.

Ajax Loading panel stays on the page infinitely

Hello, I've encountered a loading panel issue. The loading panel on my user control page won't disappear.

Please see the attached image for my page hierarchy.

I have a parent page which uses 2 same user control pages. On my parent page, I have a RadAjaxManager and on the user control page I have a RadAjaxManagerProxy.

Parent Page RadAjaxManager code:

The button1 on parent page will update panel1.

<telerik:RadAjaxLoadingPanel runat="server" ID="rAjaxLoaingPanel1" Modal="false"></telerik:RadAjaxLoadingPanel>
    <telerik:RadAjaxManager runat="server" ID="rAjaxMan1">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="button1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="panel1" LoadingPanelID="rAjaxLoaingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
    </telerik:RadAjaxManager>

User Control Page RadAjaxManagerProxy code:

The button2 on user control page will update panel2, and panel2 will update itself.

<telerik:RadAjaxLoadingPanel runat="server" ID="rLdPn" Height="400px"></telerik:RadAjaxLoadingPanel>
<telerik:RadAjaxManagerProxy runat="server" ID="rAjaxManProxy">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="button2">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="panel2" LoadingPanelID="rLdPn" />
            </UpdatedControls>
        </telerik:AjaxSetting>
        <telerik:AjaxSetting AjaxControlID="panel2">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="panel2" LoadingPanelID="rLdPn" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

When I click button1, the ajax loading panel (id=rAjaxLoadingPanel1) is working fine, it shows and hides. However, when I click button2, the ajax loading panel (id=rLdPn) will stay on the region of panel2 infinitely.

I searched some 2009 forum posts but none of them addressed my issue.

Could someone help me? Thanks very much!

How to disable javascript for RAD Controls

Hi,

We have a requirement to render a page in edit mode and read only mode.

The RAD controls that we are using are custom classes that inherits from Rad control classes. For example we have a class called CSRadComboBox that extends from the class RadComboBox and we use the instances of class CSRadComboBox in all the code for the project.

When a page is rendered in the read-only mode to the users, we override the Render method of the RadComboBox and render an System.Web.UI.WebControls.Label object with the contents in it. I have copy pasted the code used to render in the readonly mode for one of the controls below.

protected override void Render(HtmlTextWriter writer)

{

if (IsReadOnly)

{

Label lblValue = new Label();

string display = "--";

if (!string.IsNullOrEmpty(this.SelectedText))

{

display = this.SelectedText;

}

lblValue.Text = display;

lblValue.RenderControl(writer);

}

else

{

base.Render(writer);

}

We have a problem in the readonly pages that there are lot of javascript error that is thrown, "null is null or not an object" and when debugged in visual studio, we could make out that the ajax javascript from the telerik resource is trying to attach events to the labels that has been entered and since it is not able to find the actual control, the javascript error is being thrown.

We need help on how to disable javascript for individual rad controls in the readonly view of the page when actually it is not required at all.

Thanks,
Manoj

Page size

Hello -

We are using Telerik forms for our internal website. When I download one page with all its components, it is 73 files and 11.2 MB total size. Screen captures attached.

10 axd files (4.4 MB)
8 css files (328 KB)
47 js files (2.7 MB)
7 image files (84 KB)
1 html file (3.7 MB)

Most of our site is made up of similar pages. Our site has an average 500 connections per second. During peak times, the website crawls, with 20-30 seconds to return one page for each user.

We are accessing only text, with about 200 KB of text returned for each request.

It looks like 99.3% of the size of our pages is Telerik related files (mostly axd and js).

What could we be doing wrong? What should we be doing differently to reduce the size or count of Telerik files returned to the client?

Thank you!

Problem in controls that are inside a RadWindow

Hi, I'm having trouble with a control called RadWindow. I show that control inside a normal asp form. The radwindow has a ContentTemplate inside it, and inside that content template I have all the controls of the form. What happens is that when the window is maximized then when you click on a datepicker or a comobox (both from telerik) the drop-down list of the combobox is not displayed nor the calendar of the radCalendar, which could be?

CODE:

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="frmPruebaApariencia.aspx.vb" Inherits="frmPruebaApariencia" %>

Org Chart for large dataset..

I have a large dataset of employees.

I want to load one node initially and all other node collapsed and load other node on demand.

But this control is loading complete data on page load which is making it slow.

is there any way to rebind the org chart on expand and bind all child nodes?

"System.ArgumentException: Illegal characters in path" Exception!

Hi,

I'm getting the following exception multiple time throughout the application in error log. It's very difficult to identify the exact reason for exception occurrence as the application is vast to debug in depth. Also, I'm using Telerik Control as well as Telerik Reporting in multiple place in the application. The version of Telerik.Web.UI which I am currently using is 2023.1.323.45

EXCEPTION URL :

https://adba.roc-p.com:443/Telerik.Web.UI.WebResource.axd?type=rau

EXCEPTION MESSAGE :

System.ArgumentException: Illegal characters in path. at System.IO.Path.CheckInvalidPathChars(String path, Boolean checkAdditional) at System.IO.Path.GetExtension(String path) at Telerik.Web.UI.AsyncUploadHandler.ProcessUploadedFile() at Telerik.Web.UI.HandlerRouter.ProcessHandler(String handlerKey, HttpContext context) at Telerik.Web.UI.WebResource.ProcessRequest(HttpContext context) at System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStepImpl(IExecutionStep step) at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

Can anyone please provide all the possible reason behind this exception along with its step to resolve. Any help will be highly appreciated!

NOTE :

I have already visited multiple forum in which it is mentioned that this issue occurs in the previous version of the Telerik.Web.UI. Please confirm whether the exception mentioned above still exist in the version of Telerik.Web.UI which I am currently using i.e. 2023.1.323.45. And If not then please provide the possible reason that we need to verify on our end.
