Update Label With Key Value From Grid Row Selection

I'm trying to make a label control update to display the key value for the users row selection in a Radgrid. For some reason I can't get this to work. Data is populated by way of some Linq to Entities code in a separate class. Can someone show me what I'm doing wrong?

Below is the relevant code from my aspx page and code behind.

<form id="form1" runat="server">

RadComboBox.SelectedItem is null

We populated radComboBox in page_load method once it not from post back. When the user click a button and we will read selected item using following code

cmbCustAcctNo.SelectedItem.Text

However, we got object null reference because SelectedItem is null. We have verified EnableLoadOnDemand = false and AllowCustomText = false. Do we miss anything?

version: 2008.2.826.35

<telerik:RadComboBox ID="cmbCustAcctNo" Width="128px"

runat="server" Skin="Office2007" CausesValidation="false" AutoPostBack="true"

ToolTip="Select Account Number"

onselectedindexchanged="cmbCustAcctNo_SelectedIndexChanged">

</telerik:RadComboBox>

IList<prcWebAccountsForUserResult> listOfAcctNo = accountNumbers.ToList();

cmbCustAcctNo.DataSource = listOfAcctNo;

cmbCustAcctNo.DataTextField = "AccountNumber";

cmbCustAcctNo.DataValueField = "AccountNumber";

cmbCustAcctNo.DataBind();

email subject cannot be saved in the linkmanager when use IE

Hi Telerik team,

We got an issue when we use RadEditor ajax to input email address. The issue happens in IE only

To replicate issue:

1. open the editor in IE, try to input email format string ( such as 123@hotmail.com ) then enter a space after it
2. right-click on the link and select properties.
3. enter a Subject and click OK.
4. Right-click on the link and select properties, you will see the Subject link is empty.

Firefox has no such issue.

Thanks,

Editor

Referencing Ajax in the Master from a control

Hi,
I'm very new to Ajax and am trying to update a RadPanelBar on the Master page from a User Control to display or hide certain options.

The example reads like this:
1. Project page loads Control1, hide RadPanelBarItems (1 thru X) on the Master page
2. Project page loads Control 2, show RadPanelBarItems (1 thru X) on the Master page

The first page to load is Control 1, and I have been able to get #1 above to work, but then if I load Control 2 I don't get #2 above to work.

I am guessing I need to update this panelbar on the Master Page dynamically from the Project Page, but I have tried all of the examples for doing this without any luck.

RadAjaxManagerProxy's Name on the master page: "ram"
RadPanelbar's Name on the master page: "rpbMain"

Project's Page Load:
Dim AjaxManagerProxy As RadAjaxManagerProxy = CType(Me.Master.FindControl("ram"), RadAjaxManagerProxy)
Dim PanelBar As RadPanelBar = CType(Me.Master.FindControl("rpbMain"), RadPanelBar)
AjaxManagerProxy.AjaxSettings.AddAjaxSetting(rsProjects, PanelBar)

Both Dim'd objects always return as nothing and I get an object ref not set error.

Thanks,
Jason

TreeView in RadComboBox Issues

Hello,

I am trying to use the treeview in the RadComboBox: http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/treeviewcombobox/defaultcs.aspx?product=combobox

I'm having two issues I can't figure out why:

1. The text of the item isn't changing when disabled. When the control is disabled to prevent the user from changing the value, the value is not changing when set from server-side code. I have rcbCode.Items[0].Text = "New Value", but the old value still appears.
2. Initially, when hitting the drop down the first time, the drop down is pretty small, but later on it returns to the correct size. I am explicitly setting a CSS class for the drop down at 500px, but the first time it drops down to 200px.

Any ideas why?

Thanks.

Prevent editing of Certain paragraphs

I am considering using RadEditor in a system for the production of letters based on standard templates.
Some letter templates have paragraphs that have legal content, and so only certain parts of these letters can be edited.

Is there a way to prevent a user from editing certain paragraphs or areas within RadEditor?
