Fileexplorer custom file upload and refresh

I'm developing an application with a fileexplorer control on it. On the page, above the fileexplorer control, I have a custom file upload function, so I disabled the add button in de fileexplorer's toolbar.

I'm having trouble to display the newly added file in the content of the fileexplorer control. I upload the file in the current folder of the control.

I've tried using the server-side function DataBind() to refetch the contents of the folder, but that didn't work.

Second, I've added a client-side function on the OnClientLoad event, with the following content:

function refreshAfterUpload(explorer, args)

{

if (newImage)

explorer.refresh(explorer.get_currentDirectory());

}

The js variable newImage is set server side when i've added a document. This also doesn't work.

The last option I tried was calling the serverside function FileExplorer.Grid.Rebind(). However, during the postback and the upload of the new file, FileExplorer.Grid is null.

Can anybody help me? After I upload a new file in the current folder of the fileexplorer control, I want to be able to see it.

RadListBoxes disappear in IE

I have a page that doesn't use AJAX or partial postbacks. It contains a DateTextBox, RadComboBox and a RadGrid.

I added 4 RadListBoxes to the page. I have JQuery to show/hide the table that the RadListBoxes are in.

1rst problem: When the page loads in IE, the RadListBoxes aren't there. I can ge them to appear by clicking the show/hide icon that uses JQuery.

2nd Problem: If I so much as hover over the RadComboBox, the RadListBoxes disappear again. But it's only the RadComboBox control that does this and only in IE (IE9 is what I'm using).

I've removed the JQuery to rule it out. The page still doesn't render the RadListBoxes on load.
There are no other settings, properties or Javascript that is showing/hiding anything, especially around the RadComboBox.

I replaced the RadComboBox with an ASP DropDownList. The RadListBoxes show up on load, but if I select something in the DropDownList, the RadListBoxes disappear again.

Problem with upgrade Telerik

Hi, Please help me.

My project was working fine, until I upgrade Telerik to use the new radHtmlchart features.
Now, when I run my project I got this message:

Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Specify css location

This might be a bit hard to explain but basically im looking for a setting where I can specify where in the page the html editor is (in css terms) so it picks up on particular css.

It'll be easier to explain with an example.

So I hook the rad editor up to a particular css file :
radEditor.CssFiles.Add("<path to css file");

Then say in the css file there is a div with an id of test, and that div has particular style set in the css file.
What id then like to do is have the rad editor content styled as if it is located in the div with id of test, so it picks up on all relevent css relating to that div.

I think this probably isn't possible but just double checking?

RadAjaxLoadingPanel not showing

Hello,
I have a problem with RadAjaxLoadingPanel:
my web application has a RadGrid control and a RadTreeView.
When I click on a node of the radtreeview the radgrid performs a rebind action and loads data associated with the node values.

I use a RadAjaxManager to perform the update/rebind action of the radgrid and i use a RadAjaxLoadingPanel to hide the radgrid while loading data.
The update process is correctly performed but the RadAjaxLoadingPanel is not displayed.

In my application there are other controls that trigger the update action of ther radgrid and the update is correctly performed and also the RadAjaxLoadingPanel is correctly displayed.

How can I fix my problem and make the RadAjaxLoadingPanel visible during the update of the radgrid when clicking on a Radtreeview node, like with the other controls?

A short part of the code is following:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Block" EnableHistory="False">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="CheckBoxMerge">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="CheckBox1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="RadGridAccounts">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="ButtonEseguiFiltro">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="CatTree1">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadGridAccounts" LoadingPanelID="RadAjaxLoadingPanel1" UpdatePanelRenderMode="Block" />
                    <telerik:AjaxUpdatedControl ControlID="TextElementi" />
                </UpdatedControls>
            </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

CheckBoxMerge, CheckBox1, RadGridAccounts, ButtonEseguiFiltro perform correctly the update and also the RadAjaxLoadingPanel1 is displayed, while CatTree1(the radtreeview) performs the update but the RadAjaxLoadingPanel1 is ot displayed

Duplicate RadControls in toolbox

Hi,

I am using Visual Studio 2008 SP1 and have just installed RadControls for ASP.NET AJAX Q1 2010. There have been no previous installations of RadControls or Visual Studio on this machine.

After installing RadControls for ASP.NET AJAX Q1 2010 I noticed that there are two of every RadControl in the toolbox.

Why is this and is there a way to fix it?
