Hello,

I am currently working on a project with a RadTreeView.

I need only when I click on a leaf with no children it do a PostBack.
When I click on a leaf that has children, it will be performed expand/ collapse - depending on the current mode.
(If it has been expanded – it will be collapse, if collapse - expand)

I have a js code, but it’s give me an error every time I click on a node that has children:

ASPX:


VB.net:


Errors:
(The error refers to lines  10 and 14)


How to solve this problem ?
I’ll be glad for your help.

Thanks,

Daniel.

In responsive design the DropDownTree control is usually configured with width=100%
I wonder how in this case to make the dropdown width the same as the control width to make it responsive too?

Hi,

I have a radspell with controlToCheck(Textbox1) in my web form..i want to activate the radspellcheck on button onclientclick event because button  also have onclick event..i need to fire the radspellcheck before button onclick event...Simply i want a spellcheck on button submit...i have tried but onclick event only fired fiirst..could please some example please...

I have found that if you are using the ToolProvder for multiple RadEditors that the undo redo functions do not update the content when pressed ore selected from the Undo / Redo toolbar buttons or dropdowns.

The undo / redo works for the RadEditor that is the ToolProvider but not for any that use the first editors toolbar.

This can be replicated on your demo site.

http://demos.telerik.com/aspnet-ajax/editor/examples/toolprovider/defaultcs.aspx 

Replication Instructions:

• Tick Use Tool Provider
• Click apply settings

Type some content in the first editor, press undo - Text entered is removed
Type some content into the second editor, press undo - no changed to the text in this editor.

Note: The dropdown menu still contains a history of undo/redo commands

I have found that my program which includes multiple RadComboBoxes don't drop down in IE versions 9 and 10, but they work fine with IE 11 and below IE 9, could someone give me reasons as to why this is happening. 

I am using HtmlChart with scatter. I want to specify the xaxis from 7/1/2013 to Today in multiple graphics so all of them have the same xAxis no matter of the data. How I can achieve this?
How do I specify xasix min value = 7/1/2013 and maxvalue=today?

OpenArchiveWindowI have a radgrid with GridTemplateColumn that contain linkbutton :

OpenArchiveWindow() : js fct to open a radwindow :

and getArchiveLB_Click() is server side fonction to databind grid ('ConfigurationArchiveGrid') inside the radwindow ('ArchiveWindow'),

inside getArchiveLB_Click: radgrid is binded , but doesn't appears inside radwindow ,

how can i achieve that ?

I have a RadGrid hooked up to an objectdatasource, which pulls records with a GUID as it's Primary Key.  Whenever I do an update on the RadGrid I get a parse error and it shows the Guid prefixed with the PKey column name like so:

System.FormatException base Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx)
"{BoatID:\"280f5da9-4048-4569-9e8c-c3aea971b45e\"}"  I'm not sure why it's prefixing the GUID value w/BoatID.  I can see why it cannot parse this value.  I'm not sure how to fix this since Telerik handles the parsing behind the scences.

Info that may help:

hi,

i have been following this example to build a chart with drill down functionality.

this is my code... it's not fully completed but this is how it's supposed to be like. i want to drill my data in the following order starting from "Business Unit" -> "Brand" -> "Account" -> "User" 
for some reason i can only click and view 1 level of detail, that is i can go from "Business Unit" -> "Brand".
the chart doesn't allow me to click on columns that i see when "Brand" details are loaded. 
can you suggest a reason for that and a solution for me. Thank you. 

Hello.

My data source is here.
============
DataSize  || User
============
0              ||   3
1              ||   1458
2              ||   20
6              ||  1
=============

I created line chart from programmatically.

X-Axis show 6 axis 0 to 6, it's correct.
I expected line will display  0 to 6 along X-Axis.

but line display 0 to 3 (please refer 11111111111.jpg)

I would like to draw the line 0 to 6 X-Axis like this 222222222222222222222.jpg  (it drew by ASP.NET Chart control)
