If you set a specific paper size and the content that you are trying to export to PDF exceeds the size of the paper, the content is cut off. The RadClientExportManager needs to overflow this content to a new page.

This functionality would be consistent with the RadGrid's PDF export capabilities. Without it, the RadClientExportManager is only useful for generating PDFs IF one knows the exact size/dimensions of the content being exported.

Possible workarounds from Admin: 

1) Use Lightweight render mode instead of Classic: https://docs.telerik.com/devtools/aspnet-ajax/controls/render-modes#setting-render-mode 

2) Disable temporarily the keyboard navigation of the control

3) Use the attached script and load it on the page: 

3.1) Using a RadScriptManager (adjust the file name and path to fit your application)

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        <telerik:RadScriptReference Path="fix.js" OutputPosition="End" />


3.2) In an inline script tag somewhere AFTER the ScriptManager(e.g. at the end of the <form> or <body> tag)

3.3) As a script reference - place it AFTER the script manager as 3.2) or use the defer="defer" attribute

<script defer="defer" src="fix.js"></script>


4) Submit a support ticket if you would prefer a custom Telerik.Web.UI.dll assembly with the issue resolved.

The resize handle of the Editor is not visible if only only edit mode is active (e.g. Design mode).

Steps to reproduce:
1. Run an Editor with the following configuration:

        <telerik:RadEditor ID="RadEditor1" runat="server" EditModes="Design" ></telerik:RadEditor>

Result: The whole module row is not visible, including the resize handle.

Heres a simple one: I have a dynamic grid `MasterTableView.EnableColumnsViewState = false;` on page init and all works fine. However, when the client/browser show a dynamic column thats hidden (or vise versa), and the column is gone on postback (being a dynamic grid this can happen), the LoadClientState tries to get the column - and if it fails to, it breaks down hard.. Instead it should just ignore it, as its just a pretty un-important show/hide state.

Your RadGrid code goes something like this:

LoadClientState ->
if (clientState.ContainsKey("showedColumns")) ->
control.GetColumn(columnUniqueName).Display = true; <-- just ignore this if not found - also on the others like hide, resize etc.


Thank you!... +1 for making this html editor a MD flavor instead :)

These issues can be reproduced here:


1. Navigate to the above site on an iOS device (IPhone or IPad).

2. Touch the top right hamburger menu to open the Columns Display Form. 

3. Touch a checkbox.

The first touch over a checkbox or its corresponding label is not changing the state of the checkbox but at the same time, the header buttons are switched to Done and Cancel (as if changes have been made).

Touching between separate column fields changes the state of the checkbox of the upper column but the same is not updating the header buttons (Back button remains visible and Done and Cancel remain hidden).

This is a follow on request from a ticket raised where it was stated this feature isn't available and there is no work around.

When you hook a RadCombobox to a RadClientDataSource, which returns a paginated set of results along with a count of total number of records, the RadCombobox should display the "Show More Results" box along with the text stating "Items 1 - x of y" as all that information should be able to be calculated from the data returned.

When using the Designer, the Default Values displayed for properties do not reflect the Default values from Lightweight RenderMode.

One particular scenario is when creating a GridButtonColumn for RadGrid that is set to LinkButton. While the Designer shows the ButtonType set to "LinkButton" by default, upon rendering the Grid, the ButtonType is FontIconButton.

There is no way of changing that in the Designer.

I'd like to see a Drag And Drop manager functioning something like the AJAX manager.
You can select controls that can be draggable and then define drop targets for them.

Things it might include:
* Constrained movement, either X, or Y or within a boundary.
* Init distance.  Eg. you have to drag an object 20px to start moving it.
* Drag handle.
* Snap. to grid, or elements
