Cannot set DDL values after user leaves site

I have an asp.net 4 website. The default page is using the radajaxmanager The default page has two radcombobox controls. Server side OnItemsRequested events are used to populate the radcombobox controls. A radmultipage control is also on the page. Each page in the rad multi page displays data in rad grids based on the selections for the two radcombobox controls. The website uses session state to store the selections from the two radcombobox controls.

The problem is that a user can leave the website without closing the browser and then return to the website using a back button or favorite item. The comboboxes do not show the previous selections. However, the grids use the session variables to display data. I have been unable to set the radcomboboxes values. It appears that the page load event does not fire.

I cannot remove the radajaxmanager because a tab strip control is also used. The page needs javascript methods to control the tabs.

Do you have any suggestions?

inline style "width:100%" missing at header's rgMasterTable in IE

Hi,

I have a somewhat strange bug where some inline-css seems to be missing. This occurs in IE10 and IE11 and only when the site is hosted in IIS (IIS Express 8 works fine).

This is the generated html from IE11, site hosted in IIS:

<div class="rgHeaderWrapper">

<div class="rgHeaderDiv" id="Control1_SP_Grid1_Grid1_Grid_GridHeader" style="overflow: hidden; margin-right: 17px;">

<table class="rgMasterTable rgClipCells rgClipCells" id="Control1_SP_Grid1_Grid1_Grid_ctl00_Header" style="overflow: hidden; table-layout: fixed; -ms-text-overflow: ellipsis; empty-cells: show;" cellspacing="0">

And this is the generated html from IE1,1 site hosted in IIS Express:

<div class="rgHeaderWrapper">

<div class="rgHeaderDiv" id="Control1_SP_Grid1_Grid1_Grid_GridHeader" style="overflow: hidden; margin-right: 17px;">

<table class="rgMasterTable rgClipCells rgClipCells" id="Control1_SP_Grid1_Grid1_Grid_ctl00_Header" style="width: 100%; overflow: hidden; table-layout: fixed; empty-cells: show;">

As you can see, in the first case the width: 100% attribute is missing, but therefore there is an attribute "-ms-text-overflow". Because the width attribute is missing, the layout i screwed up. The software is absolute identical, the Telerik Version is Q3 2014. In both cases IE runs in edge mode.
If I try the same with Chrome, in both cases the width attribute is set correctly.

Could you tell me which logic in the RadGrid determines which attributes must be set?

Thanks!

Javascript RadAlert doesn't obey skin set in RadWindowManager

I have a RadAlert that I call with Javascript that I can't change the skin to. In my aspx page I have this Javascript called:

<script>
radalert('This is a test message.');
</script>

In the Master Page of the aspx page I have a RadWindowManager like this:

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Skin="WebBlue"/>

The radalert continues to use the "Default" skin and don't know why. How can I change it in this case?

openRadWindow() doesn't work in IE10

Hi,

I have this problem with opening the window when clicking a link. The thing is that it works in every browser I tried (Firefox, Chrome, Safari), but in IE10 it doesn't open.
The behavior in IE10 it's like this:
1. clicking the link (which should trigger the popup)
2. nothing happens
3. clicking again on the link
4. the popup appears in the top-left corner but without any content and any functionality (it doesn't display any content and the close button is not working)

The code for opening it:

<script type="text/javascript">

function openRadWindow(id) {

var oWnd = radopen("../link/" + artid, "RadWindow1");

oWnd.center();

oWnd.show();

}

</script>

And for triggering the code above:

<a href="#" onclick="openRadWindow('<%idstuffgoeshere%>'); return false;">Open popup</a>

I tried to debug it with the IE(10)'s debugger and I get the following JavaScript errors:

SCRIPT5022: InvalidCharacterError

ScriptResource.axd, line 796 character 8

SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference

ScriptResource.axd, line 128 character 2

SCRIPT5007: Unable to get property 'documentElement' of undefined or null reference

ScriptResource.axd, line 128 character 2

I haven't tried this on other IE versions, but I assume is not working on the earlier versions either.
Anybody knows a solution for this?

Input fields not available after postback

Hi,

I have a strange issue. I'm using masterpages and contentplaceholders. I have a page where I have the RadAjaxManagerProxy with a LoadingPanel.
On the page there are several object, input field, dropdown, RadDatePicker, RadEditor, DataGrid, buttons,...
When I had a postback from for example pressing a button, I have a strange situation.
Let's say I push a button to add data from fields to the datagrid, after postback I select another value in a dropdownlist and then want to input data in the RadEditor. The RadEditor is not available at that moment, I cannot click in it with my cursor, also all the other input field are not available. Dropdowns, buttons, lists are available and can be changed but no input or Editor field.

Any Idea what the problem may be?

I cannot provide a link to the site because it is on our intranet.Also cannot copy the aspx file and master file because it is too hugh...

Kind regards

Suzy

Skin not showing correctly - IE 9

I'm seeing some weird display behavior using a ListView with a data pager on IE 9. I've already told the clients they need to upgrade their browsers but not all of them will :)

Anyway, I've attached a PNG of what I see (unfortunately not ALL the time). The IE 9 F12 dev tools are horrible so I can't tell from those if a style sheet isn't loading correctly or what.

This is a scenario where I have a RadWindow which contains a RadTabStrip. The tabs' content in the strip are dynamically loaded via ASCX controls.

I'm curious if others have seen this behavior with IE 9, and if they were able to eliminate it.
