Hi Team,
i am creating Multi language selection feature in Web App using Global Resources,Local Resources and bootstrap(css and Js). But I am getting the following Error while rending telerik control.

Error:
"The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>)."

Aspx Code:
<% if (dirs == "ar-EG")
       { %>

 <link href="../bootstrap-arabic/css/bootstrap-arabic.css" rel="stylesheet" />

    <% }
       else
       { %>

 <link href="../bootstrap/css/bootstrap.css" rel="stylesheet" />

 <% } %>

Aspx control working good with  same code but issue occur while use telerik control.  
What is the possible way solve this issue Please suggest.

I haven't touched my application in some time.   This is a C# Asp.net web app using Telerik Ajax controls. I've just updated to the latest controls and I'm having a problem adding a new RadComboBox.

Up till now I have not had this problem.  Whenever I added a box it's label would always be in line on the left.

With this new box, no matter what I do, the label is always above the dropdown. 

This is within a div that has a width of 100% of the current page.

What could I be forgetting?

Hi,

I managed to get RadGantt tasks inserts and deletes working fine. But for some strange reason 
UI changes(e.g. Add Child tasks, rename task, change dates...etc.) to the tasks are not being saved.
Am I missing something obvious?

I'm using latest  UI for ASP.NET AJAX version 2017.1.116.40

Below is my declarative

I have an auto-generated grid from a datatable.  I need to find the index of 2 columns and then traverse the columns (i.e. col 4-6) and then grab the data from each cell and make it bold based on a condition. 

1 -How can I get the indexes of these if I know the header name?

2 - how do I traverse the columns and grab it's data?

 

Thanks in advance!

Hello,

We are wondering how to access the low-level appointment data (like recordset ID or internal references) in order to duplicate a selected appointment including all its settings to a new date in timeline view (v. Q2_2009).
We were looking at the exposed properties without finding something, but I guess we certainly missed something...

Edit: The selection of the appointment occurs through a contextual menu.

This has to be done server-side for technical reasons.
Anybody has an idea?

Regards,
David

I am testing out the Telerik RadGrid to see if it can replace a custom Silverlight grid we have in our product.  The problem is that our product reads the data from CouchDB as a JSON file which we de-serialize into a class (stored in a Session variable) that contains collections (System.Collections.Generic.List) of other classes.  I bind one of these sub-collections to the RadGrid.DataSource, depending on what I need to display and call RadGrid.DataBind().

Everything there works fine, except when I go to update the InPlace grid values with the RadGrid_UpdateCommand event.  I only get the old values and not the updated ones, possibly due to the PostBack resetting the values. I have found other postings of people with this issue, but they are all binding to a DataSource object like SqlDataSource.

Is it possible to update a collection bound to the RadGrid datasource?

Hi,

We have a requirement of having tabs and radDocks in the RadTabStrip. I am saving the RadDock States in the database and using hidden update Panel as shown in the example project.

Is there a way to load only the selected tab Rad Docks and their state when the tab is selected instead of loading both the tabs?

We can have maximum of 19 Widgets on a single tab, and each RadDock inclues grids, images etc... To load all the widgets it is taking a long time. Please let me know if only the selected tab can be loaded instead of both the tabs. I tried using RenderSelectedPageOnly="true" of RadMultiPage, but did not change the loading time.

Attached a sample project with DashboardPage that has 2 tabs as 2 user controls. Please take a look at this and let me know.

PS: How do I attach a zip file which contains the sample project.

Thanks for all of your help.

Hi,

When using ClickToOpen and ItemTemplates, the menu cannot be closed by touching the root item on mobile Safari (iPad)!

Works if not using ItemTemplates, it also works on desktop browsers!

Sample:

 

On an iPad, click the menu to open it, then it cannot be closed by clicking the menu item again...

Regards
Andreas
