Questions on UI for ASP.NET AJAX Forum

Hello,

is it possible to change the value returned by the SelectedValue when there is nothing selected?
I need this because it returns 0, and that unfortunatelly is a valid id in the database, and when there is nothing selected it shouldn't retrieve anything from the database, and it is retrieving, and that's just weird.

Thanks!

[Solved] Ajax RadWindow Button Clicked

I have a RadWindow that is used to update values. When the button is clicked and the event is finished the whole page reloads. I would like to apply some Ajax to the RadWindow so that the whole page doesn't reload when the update is complete, just the RadWindow closes. Below is the code I have so far:

ASP.NET

<telerik:RadAjaxLoadingPanel ID="LocationsLoadingPanel" runat="server" Transparency="30" Skin="Vista"></telerik:RadAjaxLoadingPanel>

[Solved] Possible breaking change in RadComboBox (Q2 2011) - EmptyMessage shows regardless of the values of the AllowCustomText and EnableLoadOnDemand properties

With Q2 2011 RadComboBox's empty message shows whenever there is no selected item even if the control is read-only (AllowCustomText=False, EnableLoadOnDemand=False). This has been a highly requested fix for the last couple of Qs in all of our support channels, so we finally implemented it although it may be a breaking change in some of your implementations.

In case it is a breaking change please consider retaining the previous functionality by using one of the two approaches:

for a data bound RadComboBox handle the OnDataBound event and select the first item (if it exists).
otherwise select the first item after you add items to the control.

Client Updating Method

When bound to a webservice, how do I intercept whats going to show in the panel and show something custom?

I'm returning a serialized javascript object so I want to deserialize it, and just just ONE property of the object.

This is what I've been trying, but I think the cancel is stopping the content from showing in the panel?...or is this the wrong method?

function onSaveNotificationPanel_Updating(sender, args) {

var callbackresult = Sys.Serialization.JavaScriptSerializer.deserialize(args.get_content());

//Put the content into the panel

args.set_cancel(true);

args.set_content(callbackresult.Message);

}

Can the notification control...

I can't seem to get a background of 100% width and height and a 30% opacity around the notification control. Is it even possible to do this? I realize it's just like a modal popup, but that's that point. I would love it if my notification controls could match the site more. Here is my code:

<style type="text/css">

.notificationContent

{

display: inline-block;

zoom: 1;

*display: inline;

width: 160px;

vertical-align: bottom;

}

.newBackground

{

width: 100%;

height: 100%;

background-color:#666;

filter:alpha(opacity=30);

opacity:0.7;

-moz-opacity:0.7;

}

</style>

<div class="newBackground"><telerik:RadNotification ID="RadNotification1" runat="server" Position="Center" Width="240" Height="100" OnClientShowing="OnClientShowing"

OnClientHidden="OnClientHidden" LoadContentOn="PageLoad" AutoCloseDelay="60000"

Title="Continue Your Session" TitleIcon="" Skin="Office2007"

EnableRoundedCorners="true" Animation="Fade" CssClass="newBackground">

<ContentTemplate>

<div class="notificationContent">

Time remaining:

<span id="timeLbl">60</span>

<telerik:RadButton Skin="Office2007" ID="continueSession" runat="server" Text="Continue Your Session" Style="margin-top: 10px;">

</telerik:RadButton>

</div>

</ContentTemplate>

</telerik:RadNotification></div>

Unable to set the tree view node properties on server side click event

Hi,

I have a treeview with parent node and child nodes. When clicked on any node, I need to have that node of the treeview expanded and clicked node to be disabled. The code below did not work.. I have tried setting a forecolor property to distinguish clicked node but that did not work either. Thanks for your help.

Public Sub RadTreeView1_NodeClick1(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadTreeNodeEventArgs) Handles RadTreeView1.NodeClick

e.Node.Expanded = True

e.Node.Enabled = False

'e.Node.ForeColor = Drawing.Color.Aqua

If (e.Node.Value > 9000) Then

Session("Page1ToNavigate") = e.Node.Text

Response.Redirect("~/Page1.aspx")

Else

Session("Page2ToNavigate") = e.Node.Value

Response.Redirect("~/Page2.aspx")

End If

End Sub

<telerik:RadPanelItem Text="Company View" Expanded="false" Font-Bold="true">

<Items>

<telerik:RadPanelItem >

<ContentTemplate>

<telerik:RadTreeView ID="RadTreeView1" runat="server" DataSourceID="SqlDataSource4"
