RadComboBox Filter doesn't seem to work in IE

Hello,

We are using version 2010.3.1317.35.

I'm currently having an issue with the Filter feature of the control on IE9.
It works as expected on Chrome 15 and FF7.

Here's the exact code I am using:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %>

<!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">

<div>

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<telerik:RadComboBox ID="testRadCombo1" runat="server" Filter="Contains"

AutoPostBack="True">

<Items>

<telerik:RadComboBoxItem Text="AAA" Value="1" />

<telerik:RadComboBoxItem Text="AAB" Value="2" />

<telerik:RadComboBoxItem Text="AAC" Value="3" />

<telerik:RadComboBoxItem Text="BBB" Value="4" />

<telerik:RadComboBoxItem Text="BBA" Value="5" />

<telerik:RadComboBoxItem Text="BBC" Value="6" />

<telerik:RadComboBoxItem Text="CCC" Value="7" />

<telerik:RadComboBoxItem Text="CCA" Value="8" />

<telerik:RadComboBoxItem Text="CCB" Value="9" />

</Items>

</telerik:RadComboBox>

</div>

</form>

</body>

</html>

On IE, the Filter feature just doesn't work and we are very frustrated with it. I spent more than an hour reading documentation and other sites and forums to find a solution and/or what I'm doing wrong before I decided to write here.

Is there anything I'm missing here? Is there any extra configuration for IE? Is IE no longer supported? What should we do?

Repeating: It works as expected on Chrome 15 and FF7

Thanks

Update: I've modified the aspx page by adding a meta tag as follows:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

This seems to keep the behavior compatible with other browsers, and of course, IE9.

Wish I didn't have to do this and that it would work the same on all browsers.

Calendar in Modal Popup or Window

Hi,
I have a RadTreeView in a RadSlidingPane. The tree has a context menu and one of the options is Select Date. When clicking this option, I would like to pop up a modal window or pane with a RadCalendar inside. I tried to add a radcalendar to a radwindow, but it would not work . What's the best way to achieve this?

Thanks,

set_text is not allways working on first try

Hi,
I'm using this code:

function nodeClicking(sender, eventArgs) {

var comboBox = $find("<%= radComboBoxUnits.ClientID %>");

var node = eventArgs.get_node()

node.set_selected(true);

comboBox.set_text(node.get_text());

comboBox.hideDropDown();

}

But sometimes I need to click twice on a node for the text to show up in the combobox.
I click once, and the combobox collapses but the combobox text is still the old one.
I open the combobox again and clicks on a node, this time the text is showing up.
Why is that? Can I change this code for any other "working" code?

Most of the times it works as it should, but sometimes, randomized, it's not working.

Regards,
Mattias

Dynamically adding search control in Treeview on treenode expand

Hi

I am trying to work on telerik Treeview Control in the follwoing scenario.

Client
...........Sites
................site1
................site2

If i have sites more than 100 then i am adding the serach control (textbox and a button) just above the site1 node, to give the user to enter the site name and click enter,it automatically shows the entered site.Everything is working fine.

Problem: As i am adding the search control dynamically , On page refresh(when i click on any node item) the search control disappears.

Below is my code:(below method will be called on OnNodeExpand="tree_NodeExpand" internally)

<telerik:RadPanelItem Text="ClientDetails" Expanded="True" CssClass="radPanelItem"
DisabledCssClass="radPanelItemDisabled">

<telerik:RadTreeView ID="clienttree" runat="server" OnNodeExpand="tree_NodeExpand"
EnableDragAndDrop="true"

OnClientNodeExpanded="cleinttree_OnClientNodeExpanded" CssClass="radTreeView">

</telerik:RadTreeView>

</ContentTemplate>

</telerik:RadPanelItem>

Protected Sub tree_NodeExpand(ByVal sender As Object, ByVal e As RadTreeNodeEventArgs)

If showSearchBox Then addSearchNode(e.Node, searchText)
End Sub

Private

Sub addSearchNode(ByVal root As RadTreeNode, ByVal defaultText As String)

Dim node As New RadTreeNode()

node.AllowDrag = False

node.Expanded = True

node.ExpandMode = TreeNodeExpandMode.ClientSide

node.Attributes.Add(

"IsSearch", True.ToString())

root.Nodes.Add(node)

Dim nodeSearchBox As NodeSearchBox = LoadControl("~/Controls/TreeviewControls/NodeSearchBox.ascx")

nodeSearchBox.ParentTreeID = root.TreeView.ClientID

nodeSearchBox.NodeID = root.ClientID

If Not String.IsNullOrEmpty(defaultText) Then nodeSearchBox.Text = defaultText

node.Controls.Add(nodeSearchBox)

End Sub

Kindly Help ,

Thank you in advance

Empty file after scanning uploaded file

HI there,

I'm attempting to scan uploaded files for malicious content.
I'm using the itemcommand 'UploadFile' to get a stream from the UploadedFiles property.

My problem is that regardless of content all files are uploaded with 0 bytes.
The file is created with the correct name but the file is empty.

Do I need to do something to reset the stream after reading it?
Also if I wanted to just remove the offending elements how would i do that?

protected void rfeFiles_ItemCommand(object sender, RadFileExplorerEventArgs e)

{

if (e.Command == "UploadFile")

{

ArrayList illegalStrings = new ArrayList { "<script", "< script" };

UploadedFileCollection _uploadedFiles = (sender as RadFileExplorer).Upload.UploadedFiles;

foreach (UploadedFile file in _uploadedFiles)

{

StreamReader sr = new StreamReader(file.InputStream);

string contents = sr.ReadToEnd();

foreach (string badString in illegalStrings)

{

if (contents.ToLower().Contains(badString))

{

//popup Javascript alert

ScriptManager.RegisterStartupScript(Page, Page.GetType(), "KEY", "alert('Cannot upload files with <script> elements..');", true);

e.Cancel = true;//cancel the event

sr.Close();

break;

}

// do I need to do something here? Tried file.InputStream.Position = 0;

sr.Close();

}

Thanks for any help

conditional update

I have a grid with a popup edit form and a dropdown in that form. What I would like to do is if the selected value of the drop down = 'closed', Set the SQL UpdateCommand [DateClosed] = @DateClosed

So @DateClosed = Getdate() if drop down = 'closed'
Else @DateClosed = NULL

Thanks

Appointment Height Zero

Dear Telerik!

Please, advice me on the following issue:

I create an appointment which has a very small duration (e.g. 1 minute). But when it renders it seems to get 0 px height.

Here below is the stack trace.

Can I adjust the appointment height somewhere in the code behind of the page so as to avoid this trouble?

Many thanks!

Stepan.
