Hi All,
I am battling to get the RadUpload control working in a EditItemTemplate.
I have followed the examples, tried other solutions from the forums, but to no avail.
After stripping everything back I have the following error :

Server Error in '/' Application.

It must be a problem with my base understanding of the controls, since there really isn't much to my attempts. Below I have included my stand-alone test aspx and code behind :

}

Can anyone steer me in the right direction here? I have had no success with the GridAttachmentColumn either, so please give feedback to my design as stated. I am not able to use SQLDataSource controls for this purpose, with datasets/datatables being my only communications with the data-layer/db.
Thanks,
Steele.

Need to get targetSlot for use in TimeSlotContextMenu

Seems like this should be so easy...

I'm defining a <TimeSlotContextMenus> tag within the body of my RadScheduler. Within one of the functions callable from that menu, I need to be able to access the targetSlot at which the context menu actually appeared. I tried adding a custom OnClientTimeSlotContextMenu to my page, but this function never seems to get called at all (although the context menu appears fine). What's up?

Page_Load is not firing - RadWindow

I have a page, let's call this main.aspx. Within main.aspx I have a splitter and load content into let's say [header] frame and [content] frame. I also have a RadWindow on main.aspx that I call to open for errors.

Within the [content] frame I have a grid using a edit Template to edit rows of the grid. If an update fails I reference and open the RadWindow using a method such as this:

var op = parent;

var oWnd = op.GetRadMessageWindow()

oWnd.moveTo(-1000,-1000)

oWnd.add_pageLoad(OnClientLoadMsg);

oWnd.add_close(OnClientCloseMsg);

oWnd.setUrl("RTS_Message_Window.aspx");

oWnd.show();

The problem is that none of the server-side Page events are NOT being fired.
I can see that the content is being loaded and I can debug client side window load events but why are the server-side events not being fired?
This used to work. I imagine this stopped working after Ajax 2009 Q3 release.

RadGrid and RadFileExplorer localization keys

Hi. Could you provide me with the localization (internationalization) keys for the tooltips in the "Next page" and "Last page" buttons and "page" and "items" labels in the footer of the RadGrid and RadFileExplorer controls?

Also I don't know whether I'm supposed to put them in "RadEditor.Dialogs.resx" or "RadGrid.Main.resx".

Thanks in advance.

deleteFileInputAt method throws exception in IE

I am having an issue where the client-side method deleteFileInputAt() method is throwing an exception when I pass in a zero in the OnClientFileUploaded event. It only does this in Internet Explorer. Firefox works just fine, or at least it is not throwing an exception. Any ideas please?

I have tried first calling the getUploadedFiles() method to check the count prior to calling the deleteFileInputAt(), but oddly I get a javascript error saying that the getUploadedFiles() method does not exist. I am frustrated.

Here is the function I am call in the OnClientFileUploaded event.

function resumeFileUploaded(sender, args) {

sender.deleteFileInputAt(0);

}

Cascading combobox in RadGrid Edit Form

I have the following aspx code:
<telerik:RadComboBox ID="rcbEditProject" runat="server" SkinID="ddRegular" Width="375px" AutoPostBack="True" OnSelectedIndexChanged="rcbEditProject_SelectedIndexChanged">
</telerik:RadComboBox>

And I have this code in code behind:

Protected Sub rcbEditProject_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)
Dim editedItem As GridEditableItem = CType(CType(o, RadComboBox).NamingContainer, GridEditableItem)
Dim rcbEditObstacle As RadComboBox = CType(editedItem.FindControl("rcbEditObstacle"), RadComboBox)
Dim rcbEditProject As RadComboBox = CType(editedItem.FindControl("rcbEditProject"), RadComboBox) rcbEditObstacle.Items.Clear()
Dim dtEditObstacle As Data.DataTable = Nothing
If rcbEditProject.SelectedValue = "" Then
Else
' I have the code to populate the child radcombo box .....

End Sub

Problem:
My RadGrid is in RadAjax panel. In the Item data bound for Grid I am able to populate the values fine.
My problem is when I change the value in the Parent 'rcbEditProject' combo box the selected index changed EVENT IS NOT FIRED.
If I have a break in the grid item data bound procedure it DOES trigger the Break point!
The other strange thing is that when I click the 'Cancel' button (see code below) the selected index changed event is FIRED?

<asp:LinkButton runat="server" ID="lnkCancel" Text="Cancel" SkinID="lnkGvEditText" Font-Bold="true" CommandName="Cancel" CausesValidation="False" />

Please help?
Thanks Sanjay

Default font properties for content saved

Hi,

I'm trying to set the default font properties of the saved content.

I've got a RadEditor control, I'm setting the default font and text color for the editor like below:

<telerik:RadEditor runat="server" ID="RadEditor1">

<CssFiles>

<telerik:EditorCssFile Value="~/EditorContentArea.css" />

</CssFiles>

</telerik:RadEditor>

Which works fine in the editor, however, when I save the content, using RadEditor1.Content, that styling isn't kept.

How can I set the default font and text color so that it gets saved when I save the content?

Cheers,
Ola
