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:

I would like to make long text wrap when using checkboxes. As per the attached image, I would prefer the left margin of the text to align with the green line.

I have attempted to use the sample shown in this article (https://www.telerik.com/forums/long-text-in-radlistbox)  but nothing worked.

Could you please advise the best way to make this change?

In RadDropDownTree there is option EnableFiltering.

Is there some listbox (checkbox enabled) that has same capabilities?

Or maybe a way to keep RadDropDownTree always opened?

Trying to hide the arrow on drag and drop for RadListBox.  Found a post on setting the z-index for the css style .rlbDragClue and I've tried everything, display:none, visibility:hidden, background:none, all with the !important designator, nothing works.  Always get the arrow.

.rlbDragClue {
background: none !important;
visibility:hidden !important;
z-index: -5000 !important;
}

Good day,

I am new to development with Telerik. You have a client where you have a website that has been developed with Telerik. The library used is Telerik.Web.UI version 2015.1.225.35

Explained this, I have 2 queries:
1. Telerik.Web.UI library version 2015.1.225.35 allows to use radlistbox to implement everything associated with listbox ? From what I have reviewed the documentation I understand that yes. If the answer is yes, then you can answer question 2.
2. Can you please give me examples of how to create a listbox using radlistbox since in my case what I want to do is create 2 listboxes and pass the elements from one listbox to another through a button.

I thank you in advance for the help provided.

We are using Telerik.Web.UI (version - 2012.2.607.40) in Asp.net application (.Net framework 4.6).

The application sometimes throws an exception and upon an investigation of IIS logs, we find that it is related to some Telerik issue.

please see attached log for details.

Hello everyone!

 

I have 2 listboxes where I am transferring data from one to another. You may check the attached screenshot for a better understanding of my page's layout.

The page contains a combobox and 2 listboxes.The combobox allows you to select a user from the list and then both listboxes will display the permissions this user has (on the left) and the perms he doesn't have (on the right). All of it is automatic of course and connected to a database.

Moving items from one listbox to another is messing with the order. I have tried to do the following:

Protected Sub RadListBoxSource_MM_Transferred(sender As Object, e As RadListBoxTransferredEventArgs) Handles RadListBoxSource_MM.Transferred
        SortRadListBoxes_MM
    End Sub

    Protected Sub RadListBoxDestination_MM_Transferred(sender As Object, e As RadListBoxTransferredEventArgs) Handles RadListBoxDestination_MM.Transferred
        SortRadListBoxes_MM()
    End Sub

    Private Sub SortRadListBoxes_MM()
        RadListBoxSource_MM.Sort = RadListBoxSort.Ascending
        RadListBoxSource_MM.SortItems()

        RadListBoxDestination_MM.Sort = RadListBoxSort.Ascending
        RadListBoxDestination_MM.SortItems()
    End Sub

This is not working, and the items are being added to the bottom of the list instead of being sorted to their correct position.

Thanks!

<telerik:RadListBox RenderMode="Lightweight" runat="server" ID="RadListBoxSource_MM" 
                        Height="200px" Width="100%" Skin="Material"
                        AllowTransfer="true" TransferToID="RadListBoxDestination_MM"
                        ButtonSettings-AreaWidth="35px">
</telerik:RadListBox>

<telerik:RadListBox RenderMode="Lightweight" runat="server" 
                    ID="RadListBoxDestination_MM" Height="200px" Width="100%"
                    ButtonSettings-AreaWidth="35px" Skin="Material">
