Javascript in RadCodeBlock is not loaded

Hi,

I have an aspx page that has a UserControl which is shown on a Button click in a RadWindow.

The usercontrol has javascript function's written in a RadCodeBlock that gets rendered when the aspx page loads. Now when i click the button to show the radWindow with userControl the javascript functions inside the RadCodeBlock of the userControl are not rendered.

I do know the work arounds of injecting the javascript from serverside but in terms of maintenance its a very big hassle as i would need to rebuild my entire project for a small javascript change.

I tried moving the javascript functions to the aspx page but since they need the clientId of the controls inside the usercontrol its getting difficult to have them in the aspx page.

How would i proceed?

Thanks in advance.

Batch edit delete & add new record bug

Hi, I have found some weird bugs when playing with RadGrid in batch edit mode, here's the scenario:

1. First, I will add new record, then you can see the red triangle indicating changes
2. Then, I delete this record, and then I add new record again
3. Things getting strange from now on, when you are editing fields, e.g. when you lost focus, an item in combobox is automatically selected instead of validation prompted, also after one field edit done, I am not able to see the red triangle in each cell, this happen to "the" row only.

Also, I have try the demo http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx
Same behavior is occured.

Please help me solve the bug.

Thanks,
Hon Wai

Ajax Tabcontainer tab panel problem inside iframe

I am facing some problems in an ajax tab container tab panel inside an iframe. One application has more frames. I am showing a .net application in one of the frames in that application. Screens comes perfectly.

But in that screen which has ajax tab panel (3 tabs):
By default I am showing the 1st tab. The problem is, when clicking on the second tab the screen is not loading. When clicking on the 2nd tab nothing happens. Is that behavior related to the iframe?

Buildup all tabs then hide and show on tab click

hi

I've got a tabstrip that and at present I build up the first level based on a mapping list in SharePoint, when a tab is clicked I then build the next level again based on the mapping list and the tab value selected. again for the final level it is built up using the same process.

This is proving to be time inefficient and I need to know if I can build all three levels on page load and when a tab is clicked it will show only those tabs that have the clicked tab as a parent value.

Level 1    tab-a          tab-b          tab-c

Level 2    tab-a1        tab-a2        tab-a3        tab-b1        tab-b2        tab-c1        tab-c2

Level 3    tab-a1a      tab-a1b      tab-a2a      tab-a2b      tab-a3a      tab-a3b      tab-b1a      tab-b2a      tab-c1a      tab-c2a

so here, the 3 levels would be built on page load and when tab-1 is selected then the second level is shown with only tab-a1, tab-a2 and tab-a3 shown and when tab-a3 is then clicked then the third level is displayed with only tab-a3a and tab-a3b shown.

hope what I'm asking makes sense

cheers

Requirements for pageLayout version 2014.1.225

What version of .NET is required for this release? I put this thread in the PageLayout forum because that is what is inspiring me to upgrade. Currently I am running server 2003 with NDP40-KB2836939-v3-x86 applied to get proper browser detection for IE 11. We will be moving to server 2012 soon, but I will still have sites on older OS versions. Integrating this at the Server 2003 level would be best short term for me.

RadAjaxManager - Collection was modified error

Hello

I have a RadComboBox that updates two RadGrids, each with a detail table that has a command button which opens a different RadWindow containing another RadGrid, and I'm running into errors when trying to apply RadAjaxManager controls to the page. Everything is working fine until I set the second grid (uxRolesRG) to update its window (RoleAvailUsers), which causes the page to throw a JScript runtime error whenever a new value is selected in the RadComboBox.

Error:

0x800a139e - Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Collection was modified; enumeration operation may not execute.

If there is a handler for this exception, the program may be safely continued.
