How can I close RadAjaxLoadingPanel from code behind ?

Hi, I have a RadAjaxLoadingPanel which automatically fires when my radgrid needs a data source. Great.
However, in my NeedDataSource event, I have a condition set to tell the code that it might not need to rebind.

If multiviewContacts.GetActiveView.ID = "viewContactSelect" Then

'Bind the radgrid

else

'Don't bother binding

end if

When my code doesn't need to rebind, the Loading Panel remains on the screen.

Surely, there must be a simple way of removing the loading panel from server side, code-behind. I just can't find it !

I've looked at the demo http://www.telerik.com/help/aspnet-ajax/ajax-show-hide-loadingpanel.html but I don't want to have to add 25 more lines of javascript to my page just to hide the loading panel.

...and even then - I have the issue of calling that javascript from the code behind.

Cheers,
Scott

shorten display names of multiple files?

http://www.telerik.com/community/forums/aspnet-ajax/async-upload/shorten-display-name.aspx

you guys offered a solution for shortening one filename in the above thread using the OnClientFileSelect event
Is there something that will do the same thing for multiple files? OnClientFilesSelected

So if a user selects multiple files with long names, I can display

veryveryverylong... [x remove]
anotheryverylong... [x remove]

I tried to get some documentation from http://www.telerik.com/help/aspnet-ajax/asyncupload-onclientfilesselected.html to figure it out but there isn't much info here. Are there other sources of info for these events?

thanks...Steve

AddNodesTo for Adding nodes directly to treeview

I am referring to the following link for adding nodes on the client side in the treeview.
http://www.telerik.com/community/code-library/aspnet-ajax/treeview/radtreeview-s-addnodesto-method-as-best-performing-solution-for-creating-new-or-moving-existing-nodes-on-the-client-side.aspx

Is it also possible to add the nodes at level 0, i.e. directly under the treeview instead of a node. I tried this approach, it worked for adding nodes under a node, but not under treeview. Can you please let me know where I might be going wrong.

[Solved] Is Visual Web Developer (Express Edition) supported?

Sometimes in the documentation I see VS 2008 and VWD used together - and supported equally. However, I attempted to install the VS Extenstions, and while the installer (.msi) ran and didn't report any errors, there aren't any Telerik specific menu items, context menus etc (as seen in the VS Extensions Video). Is this a limitation of VWD?

Edit: I guess I should add I'm using VWD 2008 (Express Edition) SP1
(Version 9.0.30729.1 SP)

image blocks client postback

When the following is set for a grid:

</ClientSettings>

and an image is in a grid cell, clicking on the image does nothing. Clicking in the grid cell outside of the image causes the row selection and postback as desired.

The image is not a button, it is just an image that represents a visual cue about the row of data for the user, in this case a picture of a lock.

The workaround we found in IE was to set the onclick of the image to onclick='this.parentElement.click();'

This causes the desired postback and row selection.

The problem? We noticed that in Chrome this approach doesn't work. I simply need a way of causing the built in row selection and postback just as if the user clicked in the surrounding td of the image.

I can get the desired behavior in Chrome by setting the image css pointer-events property to none.
Unfortunately, this disables all pointer behavior including tooltip popups.

Setting Default Html Content in RadHtmlField

Hi Everyone,

I tried setting "Html" attribute of "RadHtmlField" to set some default html content when the page layout loads in SharePoint. However, this default value was not set as expected. Following is the code from page layout,

<telerik:RadHtmlField id="myfieldid" FieldName="myfieldid" runat="server" Html="<h1>my default content </h1>" >

</telerik:RadHtmlField>

Any help to set default content for this field is very much appreciated.

Thanks & Regards,

Cannot Expand/Collapse/Check/Uncheck RadTreeView and Expand/Collapse RadPanelBar

Dear Supporter,

I'm using the RadTreeView inside the RadPanelBar to build webpart for SharePoint 2010.

Everything works fine except that users cannot expand/collapse or check/uncheck the tree view. I have enable the CheckBox for treeview.
It just doesn't happen to RadTreeView control only but also RadPanelBar which I cannot expand or collapse the bar item.
Please note that both Telerik.Web.UI and Telerik.Web.Design files are deployed to GAC.
After googling and search through some existing deploying the RadControl to SharePoint or IIS, I have summarized and get those to update in the Web.Config as following; however, there is still no luck.

Please advise which how to make the control to be expanded/collapsed or checked/unchecked based on user Mouse interaction.
