Trying to solve InsecureExternalStyleSheetException

When attached to my w3wp.exe process for my DNN 7 website, I receive a flood of InsecureExternalStyleSheetException's

Exception Data:
Telerik.Web.UI.InsecureExternalStyleSheetException occurred
Message=The style sheet '/js/dnn.js' is not located in any of the 'Style Sheet' folders designated in the web.config.
Source=Telerik.Web.UI
StackTrace:
at Telerik.Web.UI.ExternalScriptHelper.ResolveSecurePath(String scriptRelativePath)

Looking this up, it's saying that I need any folder that has a css file to be in a list of folders described by the appSettings key of Telerik.Web.UI.StyleSheetFolders.

Here are the two related settings:

<add key="Telerik.Web.UI.ScriptFolders" value="~/Scripts/;" />
<add key="Telerik.Web.UI.StyleSheetFolders" value="~/admin/ControlPanel/;~/DesktopModules/Admin/Authentication/;~/DesktopModules/Brick/User Dashboard/;~/DesktopModules/DNNCentric-AJAXFAQ/;~/DesktopModules/DNNCentric-AJAXFAQ/themes/skindefault/;~/DesktopModules/EasyDNNRotator/Controls/ChameleonRotator/static/common/;~/DesktopModules/EasyDNNRotator/Controls/ChameleonRotator/static/themes/callisto/;~/DesktopModules/EasyDNNRotator/flowplayer/skin/;~/DesktopModules/TabsPro/templates/blitzer-simple/;~/Portals/_default/;~/Portals/_default/Containers/Brick/;~/Portals/_default/Containers/Gravity/;~/Portals/_default/Containers/TabsPro/;~/Portals/_default/Skins/_default/WebControlSkin/Default/;~/Portals/_default/Skins/Brick/;~/Portals/_default/Skins/Brick/bootstrap/css/;~/Portals/_default/Skins/Brick/css/;~/Portals/_default/Skins/Brick/js/colorpicker/css/;~/Portals/0/;~/StaticContent/kendo/styles/;~/js/;" />

I made sure that any folder on any page that loads a css file is included in that list (the second one).

When I try to add /js to ScriptFolders, it causes 404's on 2 of the 3 WebResource.axd calls for any page that is generated by DNN. One of those seems to be rather important as it causes Sys to be undefined and kills most of the other javascript on the page.

Avoid reloading of dynamic pageview on postback

Hi I have a RadTabStrip which has several RadPageView. And I am creating dynamic tabs and pageview for the tabs. Each Pageview has a user control.Within the user control i am rendering a form which is also created dynamically. My problem is that when an event occurs such as button click (edit/save) on one user control, it again loads all the User controls, since the tabs and pageviews are created dynamically i have to recreate all tabs and pageview again. So, all the user controls loads again.

I just want only one user control to do post back, such as save, while keeping other tabs and pageview intact without reloading it.

Is that possible?.

Thanks.

Custom FileBrowserContentProvider w/ Azure Multiple Users and Paths

Hi,

We have a custom FileBrowserContentProvider set up to use Azure blob storage. It's coded to set the Azure storage container name when it is instantiated. What happens is when UserA opens the form with the RadEditor, it is initialized with PathA and when UserA then opens ImageManager they can work with their files. When UserB opens the form, it is initialized with PathB and UserB opens ImageManager and they can work with their files. But then UserA is still on the form, and re-opens ImageManager and they see UserB's files.

Is there a way to implement this so that it is safe for each user, with their different paths, to use? Preferrably without Session variables, because it's also possible for the same user to have multiple paths on different pages opened at the same time. Thanks

LineSpacing with tools xml file

Hi,

Is there a way to implement line spacing in the RadEditor tools while using . file? The docs show how to do it with markup but not with the tools file. I can add it as a button in the tools file, but it shows it is not implemented and I don't know how to add the options to it. Thanks

RadGrid read GridTemplateColumn

I have a grid with items that are only read in code, both on client and server side and not all of them are editable by the user.

Here is part of grid setup

<telerik:RadGrid ID="RadGridM" runat="server" DataSourceID="DatabaseItem" OnPageIndexChanged="PageChange"

AutoGenerateColumns="False" GridLines="None" AllowMultiRowSelection="true" EnableViewState="false"

Skin="Office2007" AllowPaging="True" PageSize="25"

AllowFilteringByColumn="True" OnPreRender="RadGridM_PreRender" >

<telerik:GridTemplateColumn DataField="QtyOrd"

HeaderText="Qty Ord" ReadOnly="False" SortExpression="QtyOrd" UniqueName="QtyOrd" Visible="true" AllowFiltering="false" >

<asp:TextBox ID="txtQtyOrdI" runat="server" Text='<%# Bind( "QtyOrd") %>'

Visible="true"></asp:TextBox>

<%

# DataBinder.Eval(Container.DataItem, "QtyOrd")%>

</ItemTemplate>

<asp:TextBox ID="txtQtyOrd" runat="server" Text='<%# Bind( "QtyOrd") %>' Width="10pt"></asp:TextBox>
<asp:TableCell><asp:CustomValidator ID="Validate_Qty" runat="server" ControlToValidate="txtQtyOrd" ErrorMessage="Amount must be greater than 0." OnServerValidate="CustomValidator_Qty"></asp:CustomValidator>

</EditItemTemplate>

</telerik:GridTemplateColumn >

<telerik:GridBoundColumn DataField="ItemNumber" HeaderText="Item Number" ReadOnly="True" SortExpression="ItemNumber" UniqueName="ItemNumber" Visible="true">

</telerik:GridBoundColumn>

</Columns>

</mastertableview>

</telerik:RadGrid>

<asp:Button ID="Selection" runat="server" Text="Add Selected" onclick="Selection_Click" />

On the server side when the user presses the Selection button I need to read all the values of each line on the RadGrid.
I am able to get the items with a GridTemplateColumn using this code

foreach (GridDataItem item1 in RadGridM.Items)

{

GridDataItem item = (GridDataItem)item1;

TextBox QtyVal = item.FindControl("txtQtyOrdI") as TextBox;

}

This does not work for the GridTemplateColumn, ItemNumber

I have tried getting the DataRowView, and adding the Item Template to the GridTemplateColumn, but the value or item comes back null.

I have also tried item["ItemNumber"] and item["ItemNumber"].Control[0]

If I have a grid that does not allow any editing, but diplays values I need to process server side, and all items are in the form, below, how to a loop through each row on the server side and read the text from every column?

<telerik:GridBoundColumn DataField="testvalue" HeaderText="testvalue"

SortExpression="testvalue" UniqueName="testvalue" Visible="true" ReadOnly="True">

</telerik:GridBoundColumn>

I have also tried the things in this post, and they only work on an Item Template.

Thanks

RadEditor - Image Manager - Custom File Dialogs - Javascript Reload

Hi

We are using RadEditors with Image Managers that use a custom file dialog via FileBrowserContentProvider. The reason is that our images need to go through an approval process before they can be added to the content. Everything is working except when a new image is added.

When you click on the image manager icon the first time, it fires the ResolveDirectory() override in our code and all is good and displayed correctly. Now the users adds a new image that goes through our approval process (on another control on the page, not part of the radeditor). Now the user clicks on the Image Manager again, but the ResolveDirectory() override does not fire again (I put a break in my code to test). And thus the user does not see the new image and has to click the refresh button. Although this is minor, it is generating a lot of support calls from users.

Is there a javascript method we can use to force the Image Manager and similarly the Document Manager to refresh?

Thanks
