How to retrieve Session value from JavaScript

Hi,
In my current project, I am using Visual Studio 2008, .NET Framework 3.5 and Telerik 2011 Q1.
On one of the web pages which use a common master page, I need to retrieve the value of a Session whose is set by the code behind.

<asp:Content ID="Content1" ContentPlaceHolderID="Main" runat="server">
   <script type="text/javascript">
   function showConfirm() {
   var exist = '<%= Session("SubscriptionsExist")%>';
   ...
   }
   </script>
   ...
</asp:Content>

I got the following error message
Compiler Error Message: CS0103: The name 'Session' does not exist in the current context

If I used the following instead
var exist = '<%= Session("SubscriptionsExist")%>';
I got the following error message
Compiler Error Message: CS1955: Non-invocable member 'System.Web.HttpContext.Session' cannot be used like a method.

Can you please help me?

Regards,
Herman

Override Default Styles

Hello,

Maybe I don't understand correctly but I thought that I could override the default css styling....?? For example

telerik:RadTreeView ID="MyAppsTreeView" runat="server" CheckBoxes="True" TriStateCheckBoxes="true" CheckChildNodes="true" Skin="Windows7">

<Nodes>

<telerik:RadTreeNode Text="Centura Health Resource" Expanded="true" CssClass="CategoryNode">

<Nodes>........

and I have a css file:

.CategoryNode

{

width: 186px !important;

height: 35px !important;

background: transparent url('../images/PhysSteth.png') no-repeat !important;

}

The image displays as it should but the width and height do not???

Any help would be greatly appreciated.

Radgrid - How do I close the OTHER edit forms?

I have a RadGrid where each row has an Edit button that opens an edit form that is in a Web UserControl.

These work fine. Say I edit row 1, but then click on the Edit button on Row 2, Row 1 closes as expectd.

However, If I click on say row 1 but then click the Add New Record link, Row 1 stays open along with a new blank form for the row I am adding.

When Adding a new record, how do I close all other edit forms?

related comboboxes

Hi All,

I am following the example of the related comboxes.
http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx

I have two related comboboxes and an add button Once the user selected from both the radComboBox_filters and radCombox_E comboxes, he can add the selection to the listbox RadListBox_EFilters on the right side.

My problem is that radComboBox_filters does not display "Select filters" at the top of the comboxBox because I want to display "select filters" at the top of the combox. Also, If I select something from the RadCombobox_filters, the radCombox_E will be populated with data. Once I select something from the radcombox_e and click the add button, radCombox_E gets cleared out. I don't want the radCombox_E to be cleared out just becasue I clicked on add button.
How can I fix that because I don't want the readCombox_e to be cleared out once i push the add button. Below is my code.

<script type="text/javascript">

var ECombo;

function pageLoad() {

ECombo = $find('<%= RadPanelBar1.Items[0].Items[0].FindControl("RadComboBox_E").ClientID %>');

}

function RadComboBox_E_Load(combo, eventArgs) {

var item = eventArgs.get_item();

ECombo.set_text("Loading...");

if (item.get_index() > 0) {

ECombo.requestItems(item.get_textElement().innerText, false);

}

else {

ECombo.set_text(" ");

ECombo.clearItems();

}

function ItemsLoaded(combo, eventArqs) {

if (combo.get_items().get_count() > 0) {

// pre-select the first item

combo.set_text(combo.get_items().getItem(0).get_text());

combo.get_items().getItem(0).highlight();

}

combo.showDropDown();

}

</script>

<telerik:RadPanelBar ID="RadPanelBar1" runat="server" Width="1500px" BackColor="#E6E6E6" ExpandMode="MultipleExpandedItems">

<Items>

<telerik:RadPanelItem runat="server" Text="Filters" Expanded="true">

Using PerformInsert on grid

Hi All, I am using the Demo code for using the automatic editing features of the grid, but regardless of if I "edit" a record or "Insert" a record, only the "Update" ever shows, "Insert" Button never does. Using the following code:
Q1 2011

RadGrid settings

AllowAutomaticInserts="true"

AllowAutomaticUpdates="true"

AllowAutomaticDeletes="true"

Command buttons: "Insert" Button never shows.

<td colspan="99">

<asp:Button

ID="btnUpdate"

Text="Update"

runat="server"

CommandName="Update"

Visible='<%# !(Container is Telerik.Web.UI.GridInsertionObject) %>'>

</asp:Button>

<asp:Button

ID="btnInsert"

Text="Insert"

runat="server"

CommandName="PerformInsert"

Visible='<%# Container is Telerik.Web.UI.GridInsertionObject %>'>

</asp:Button>

Thanks,

Matt

Vary Popup Format at Runtime

My RadGrid shows a Popup for Insert and Edit actions on a row.

In the Popup, I need to set a RadTexbox.Enabled = True/ False based on the value of a RadComboBox in the Popup.

Is there an example demonstrating this?

Thank you,

Rick
