Hi

I have a RadPane which loads an aspx page that contains a RadComboBox.

A Javascript function on the parent page is trying to find the element - 

$('#RAD_SPLITTER_PANE_CONTENT_MyRadPane').contents().contents().find("#" + cbo.id)

However, this returns just a jQuery object which is not useful when I want to manipulate the items using get_items() etc.

How can I get the Telerik client object in this scenario?

Thanks in advance.

Hi,

I am facing an issue with the tab index order. The expected tabindex order should be ‘header – body – footer’ but the order is ‘header – footer – body’. After tabbing the last column in header, the tab should go to first checkbox in the 1st row, but the tab is going to the page nation in the footer, and after that it goes to the first checkbox in the 1st row. I checked in the developer tools and noticed that Telerik control renders in html as <thead>, <tfoot> and <tbody> which is disturbing the tab index order. Please let me know how can i resolve this issue? I am using 2016 version of telerik.ui.dll.

Thanks in advance.

Hello --

I have a custom task class and a custom provider (non-EM). Both follow the model code, and work perfectly on page load.

When changing values, the server side TaskUpdate event fires, and e.Tasks(0) has the expected values for the task that was just updated.

However...

Problem 1: e.Tasks(0) is a standard Task object, and not my CustomTask object. How can I get my custom field values on TaskUpdate?

Problem 2: Sender, while containing the appropriate RadGantt properties set on the .aspx page, does not have the Provider I gave it on Page Load. Also, Tasks contains zero object and GetAllTasks returns nothing.

I'm not sure what code will help, so I'll just post it all.  Sorry for the length.

The page code-behind:

    Private Sub RadGantt1_TaskUpdate(sender As Object, e As TaskEventArgs) Handles RadGantt1.TaskUpdate

       ' Both sender and RadGantt1 have no tasks here!

       'e.Tasks(0) is a standard Task object. How can I get my custom column data?

   End Sub

Lastly, sorry for the huge clip, but I don't know what could be significant.

Here's the custom provider. It seems to work fine.

Hi, 

   I am looking for ideas to display each row in two lines, as shown below.

  | col1  |   col 2 |  col 3  | col 5| col 6 |

  | col7  |  Edit button | Save button   |

Please suggest for any ideas, if possible.

Thank you,

Is it possible to apply Bootstrap styling to a version '2013.3.1324.40' RadGrid? 

(Please don't discuss upgrades.  It's just not politically possible at this time.)

Hi,

I have a site where I display a list of available Camps that the users can register for.  What I would like to do is group them by "CampStartDate".  I have the code below but no matter how I try to group, I always get the error "The RadListView control does not have an item placeholder specified."

Hi,

My application requires to have grid navigation with up/down arrow keys and this is working, however, changing the selected row does not generates

raises the SelectedIndexChanged in the server side which I need to execute some other code to populate a panel with other information. The  SelectedIndexChanged  is only raised if a row is selected with a mouse click, and I need it to happen when changing the selected row with the arrow keys.

How do I need to configure the Grid to support this behavior?

Hey I have a RadGrid that pulls information from the database and I'm using my NeedDataSource Event to pull the data from the DB, make a few tweaks and assign it to my RadGrid DataSource property. We're using the default paging,sorting, etc and what happens when a user moves to the next page is that the NeedDataSource even is fired again and my data starts pulling from the database again and goes through the same process and it just went for no apparent reason. Is there a way to use the existing DataSource that is already in the RadGrid ? For Reference I'm using Telerik.Web.UI Version 2013.1.403.35

Thanks
