Recently, our pie chart has stopped displaying. The JS console says:

and on MouseOut

The HtmlChart object is defined on the aspx side and populated from the vb side.

However, even when taking the example directly from http://docs.telerik.com/devtools/aspnet-ajax/controls/htmlchart/chart-types/pie-chart, the example does not display, and the console gives me the same error messages.

We are using version 2017.1.228.45.

(Full JS error messages at the end.)

As you can see, the two template items were the only items in the menu. I then used Radmenu1.Insert(1,“Menu Item”) to put items between these templates. This works great unless there is a postback  in which case the radmenu items of the two initial templates are instantiated without the templates (On initial display the page works just fine, only on a postback is there a problem). Telerik told me it had to do with the viewstate and how insert worked and suggested I use the information from the following article ( http://www.telerik.com/help/aspnet-ajax/menu-templates-runtime.html)  to dynamically insert my templates.

 The deal with the article is it assumes the template is going to be applied to every item in the menu,  which for me is not the case. Based on article I created me a litTemplate class:

It uses the new function to set the id for the template item.  Then, it uses the Text property from the radmenuitem to determine what the literal html to be inserted is.  

 I changed radmenu definition to:

I then used the following code at the end of my menu to always add the user login information with a Logout link:

This creates the literal text template and sets the itemtemplate for the radmenu to the template. Now when a new radmenuitem is added it uses the template.  I then set it back to nothing so additional radmenuitems do not use the template. 

So I guess the trick is just setting the Radmenu.ItemTemplate before adding an item then setting it back to nothing when done.  It is a pretty simple way to use templates on a  per radmenuitem basis if your dynamically building your menus.

This litTemplate is flexible enough that I also used it to handle the logo as the first element of the menu. Using this technique, you could "literally", pun intended, insert anything in the menu.

Hope this helps someone.

How do I fix the height  in upload window so I do not need to scroll to access the button....

See attached image

When I clicked expand button in Hierarchial Grid, only the event of MasterTableView's OnNeedDataSource event is fired but DetailTablesis not expand.

After that I got javascript error as follow：

C#

In my wizard code, I want to send the user to a specific step based on a condition.

I can set the ActiveStepIndex to the index of the step but I am unable to figure out how to get the stepindex of a specific step based on the ID of the step.

Please suggest.

I have a RadGrid inside of a Wizard step. 

Why is the GridTemplateColumn container control disabled when the Tab is disabled and then enablled? if I have the Wizard Step enabled=false and then set it to to True in client-side code, the RadButton inside of the GridTemplateColumn is disabled. If i set it to True from the start the RadGrid controls are fine.

What the heck?

First off, I think the Gantt is a nice little tool and I understand this is the first version but I'm encountering so many issues. Maybe these can be addressed in the next release or maybe I'm doing something wrong. 

1. When I try and enter a date manually, I have to enter the date with a space before and after it in order to take. I can't enter a 4 digit year either. Then when the "invalid date message is displayed" it is over the calendar so I can't even select a month because it is behind the message. 

2. If entering a start time, it must be after the end time. I understand this is a requirement, but what if I'm choosing the start date first? With the autoupdating, I have no control over when the database gets updated. I'd rather allow the user to select the dates (they might not always select the end date first) then save. 

3. There is no support for programmatic databinding. I don't understand why the method is there if it doesn't work?

4. There is no easy way to delete tasks without finding it on the calendar and then deleting it. It would work better if the calendar would automatically navigate to the task in the calender, but I'd rather be able to right click or have a delete column on the grid. Unfortunately there are not template columns available or options to build in my own delete functionality. 

5. When a task is a single day, I still can't figure out how to delete it. I have to make it at least 2 days to see the delete icon. Also, there is no way to modify a single day task from the calendar. 

6. Dependency should be an option and not a requirement. This is certainly a nice feature but it really gets confusing looking at these lines. There should be a way to turn this off. 

7. After playing with the Gantt for a while I occasionally get Javascript errors "Maximum call stack size exceeded" and the Gannt simply doesn't respond.  

8. Grid columns should be resizable. 

9. The Add Task button's text should be customizable, along with the split button text. 

10. New tasks are automatically added at the beginning of the calendar. It would be nice if the columns in the calendar were selectable and a new task was added to the selected day.

11. It would be nice to have a printing option for the calendar. 

12. I don't see a way to delete dependency lines. 

Again, I do understand this is a first version, but with so many obvious bugs, I just can't believe it was released. Hopefully some of these can be addressed in the next release. I wanted some of our users to start testing the new Gantt, but I wouldn't dare have them look at it in this state as it is almost unusable in my opinion.
