Hello,

I need help on Drag and Drop feature for RadGrid, Please is the my requirement.

 

We have 140 columns in a table, we need to show them in RadGrid based on the user choice by dragging from RadListBox.

 

We need to have a accessibility to drag columns from RadListBox to RadGrid to show selected columns and also drag column from RadGrid to RadListBox to hide columns from Grid.

 

I have achieved to show selected column from RadListBox but I donot have idea to hide columns based on dragging from RadGrid to RadListBox, Please help me on this.

 

Thanks,

Kiran

I have an annoying problem that I would like to see if it can be reproduced. For every Radcombobox I add to a page, IE8 will add a click sound. So 5 rcbs, 5 click sounds on pageload/postback. The number of clicks is not easy to count until I turn on my debug bar which slows down the script firing process. I have a modal search window with 10 radcomboboxes, so every postback I can clearly hear 10 clicks. I would post code, but I can easily create the problem by just creating a page and start adding comboboxes to it. I have seen this behavior talked about in relation to iFrames in IE. I do not get this behavior when viewing demos on the Telerik site, although I am not sure what type of skullduggery is in the code on those pages.

I am using Telerik.Web.UI, v.2012.3.1016.35. This is for an external site so syaing "just use Chrome" will not help.

Please Help. Thanks.

I had a problem with the script and style managers. My web site uses a separate box to handle SSL, so when requests get to my servers, they are always http. So the managers use http to access the CDN, However, if the requested page is actually secure, this cause mixed content warnings and failed pages.
However, this is not ideal. I would rather not have to hard-code your cdn urls in my app. It would be nice to have a property so I could tell the managers that they need to access the secure urls, even when the web server is handling an insecure request.

I resolved this by setting the BaseUrl property to the secure address

    CdnSettings-BaseUrl="https://d35islomi5rx1v.cloudfront.net"

However, this is not ideal. I would rather not have to hard-code your cdn urls in my app. It would be nice to have a property so I could tell the managers that they need to access the secure urls, even when the web server is handling an insecure request.

I am new to ListView and looking for some initial guidance on technical approach for the following:

I hav a list of items displayed from a SQL datasource. The user has only one editing need, namely select yes or no via checkox.

I would like to present this list so that all list items are editable (the checkbox) without any action on the part of the user. I understand I need to build a list of "editindexes" after the dataset is filled. (I have an example picked up here, but it is in C and I only understand VB)

If I get those checkboxes to be editable, what is my next step in being able to respond to the user's selections?

Since the controls are databound, I am thinking that there would be an event on each checkbox selection that might be appropriate, or that all the boxes would be processed if I added a Save button and did something to commit the changes back to the database.

As you can see, this is my first venture into editable datasets and databinding, and just need to pointers on where & how to proceed.

I'm having an issue retrieving the type of a control if it is a Combobox.  All other control types work fine but the combobox always gets reported back to me as type "text".  Here is some trimmed down, generic code that will illustrate what I am trying to do.  This javascript is placed in a shared JS file that is executed on every page and will be invoked any time a person presses down or enter on their keyboard.
 
Thanks in advance.

We previously used the following in a ToolsFile.xml to allow users to change the current paragraph to a blockquote.


We're moving everything over to format sets in a new ToolsFile.xml. I thought the following would work, but the blockquote options do not appear in the format sets drop-down when a paragraph is selected.


Is there a way to allow users to change a paragraph to a blockquote using RadEditor?

Hi everyone
I have a question related to copy and paste cell values in a RadGrid.
Is it possible to implement the functionality of Excel?, where user can select cell and drag mouse down to desired row, and value of the first row is copied to all selected rows (drag and repeat values down).

Thanks.

Hi ,
             
I'm using Rad Grid and i assigned data table as data source for RadGrid on my project. i need to freeze the Rad Grid first 2 rows excluding Headers. I need solution for this urgent.... help me out on this...


thanks in advance,
Alexis.

I have been using a 2012 Q2 release for a good while and have been using the Org Chart. With the Q3 update, I noticed it was now possible to get the node or item ID from client side javascript code (the Edit Employees demo). I've updated my Telerik version to the latest stable Q3 (2012.3.1016) and am getting javascript errors on page load. The error is as follows:

Uncaught TypeError: Cannot read property 'groupItems' of undefined                      ScriptResource.axd:774

I have copied the client side code exactly from the demo for showing/hiding the context menu. The following lines fail with an error (most likely due to the initial error):
var item = org._extractGroupItemFromDomElement(target);
var node = org._extractNodeFromDomElement(target);

The error for these two lines is:
Uncaught TypeError: Cannot read property 'nodes' of undefined                        ScriptResource.axd:788

Here is my definition of the Org Chart in the ASPX file:


Additionally, I should mention I am using the .NET 3.5 assemblies as this org chart is being hosted on a SharePoint 2010 Application Page. I am also using an AjaxManager to ajaxify the org chart based on various controls on the page. However, the same issue happens without the org chart being ajax enabled.


************EDIT: This is easily reproduced by having grouping enabled with two or more groups that do not have a parent set (so two groups that are not linked hierarchically, they are at the same level with no children or parents). Because of the initial error, dragging and dropping is broken and cannot be used to establish a hierarchical definition and thereby fixing the issue.

Hi!.
I have the following scenario

- Master Page
- Content Page.

In Content Page I Have a Grid
This grid contains a ImageButton "Assume".. When the Admin click on "Assume"  (captura1.png)--> The app execute some actions an assume the user selected and redirect to main page. (captura1.png)
