Hello,

I have a placeholder inside an update panel as showing in the below Code block.

<tr

>

<

td

>

<

asp:UpdatePanel ID="UpdatePanel36" runat="server" UpdateMode="Conditional"

>

<

ContentTemplate

>

<

asp:PlaceHolder runat="server" ID="Fields"

>

</

asp:PlaceHolder

>

</

ContentTemplate

>

<

Triggers

>

<

asp:AsyncPostBackTrigger ControlID="DropDownList2"

/>

</

Triggers

>

</

asp:UpdatePanel

>

</

td

>

</

tr>

I dynamically create some Comboboxes as showing below

.....

Dim dropDownList As

DropDownList

dropDownList =

New

DropDownList

dropDownList.ID = array_action_ids(i)

dropDownList.Visible =

True



dropDownList.DataSourceID =

"SqlDataSource2"



dropDownList.DataTextField =

"LEGAL_PHONE_NUMBER"



dropDownList.DataValueField =

"LEGAL_PHONE_ID"

Fields.Controls.Add(GetLiteral("<td>"

))

Fields.Controls.Add(dropDownList)

Fields.Controls.Add(GetLiteral(

"</td>"

))

.....

I also have a submit button.
I want to get the selected value of the dropdownlist when the button is clicked.

I tried

Dim dropdownlist_phone As DropDownList = CType(Fields.FindControl("DropDownList_Phone"), DropDownList)

but it didn't work. I also tried

Dim temp_Placeholder as Placeholder = CType(UpdatePanel36.FindControl("Fields"), Placeholder)

Dim

dropdownlist_phone As DropDownList = CType(temp_Placeholder.FindControl("DropDownList_Phone"), DropDownList)

but it didnt either work.
The controls of the Fields placeholder seems to be nothing in both approaches.

Could you please help me?

Thanks in advance,
Peny

Error when adding RadEditor to RadGrid

Hi Guys,

I'm getting this error when I start to use the RadEditor inside the RadGrid: I created a dummy web page and the RadEditor was totally functional, so I cut and paste it into the RadGrid on another page and the resulting error is happening. What could be the problem?

Telerik.Web.UI.GridColumnCollection must have items of type 'Telerik.Web.UI.GridColumn'. 'telerik:RadEditor' is of type 'Telerik.Web.UI.RadEditor'.

Drag and Drop Problem

Hi Telerik Support

I'm trying to use the Drag and Drop functionality of the RadListBox in my project but without success.

I have looked at the demonstration page which works fine. However when I created a new aspx file in my VS2010 project and copied the demonstration code into it, the Drag and Drop functionality did not work - the transfer buttons did work.
I am developing using Visual Studio 2010 on Windows 7 (SP1) and using .NET4 with RadControls ASP.NET AJAX Q2 2010.

I would welcome any suggestions.

Many thanks

Adding Wiki Toolbar Button for Pop Up

OK, excuse this question if it's a simple solution. I'm not a code monkey and have limited experience with Sharepoint development. I was tasked with adding a Wiki to my company's current Sharepoint site. Easy enough with the existing Wiki built in.

The user's of the site want to be able to insert a link into a wiki page that will open a pop up window and display some text. I know how to create a pop up with Javascript or HTML but don't know how to implement it as a toolbar button that a user can click enter some text for the displayed link and then enter the text that will be displayed in the pop up window. It looks like i should be able to do this with RadEditor Lite but I'm a little lost. If anyone can offer some help it would be appreciated.

Thank you,

Eric

How can I specify that I only want the ajax feature (I do a SaveAs() in FileUploaded, so when the second event is fired, it throw an error)

Thank you in advance !

Small memory leak with attributes

Hi,

When setting custom attributes server-side, it seems like IE9 leaks some memory when posting an updatepanel.

Sample:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="menumem.aspx.vb" Inherits="WebApplication4.menumem" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

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

<telerik:RadScriptManager ID="ccc" runat="server">

</telerik:RadScriptManager>

<div>

<asp:UpdatePanel ID="up" runat="server" ChildrenAsTriggers="true" UpdateMode="Conditional">

<ContentTemplate>

<asp:Button ID="aa" runat="server" Text="Hit me multiple times" />

<telerik:RadMenu ID="rm" runat="server">

<Items>
