Upload not working on large files under IE but works for Firefox

We have a Telerik upload control on a Website running under Framework 4.0 that brings the file into a folder on the file server. This functionality is working when ran from Internet Explorer v8.0.7600.16385 from a Windows 7 PC. When I use a TEST PC that is running Internet Explorer v8.0.6001.18702 on Windows XP, large files (the one I am testing is 136 MB) that worked on the Windows 7 PC are not uploading. The behavior is that the status bar just indefinitely appears to be loading and it just hangs there.

To throw something else odd into the works, Firefox 3.6.8 is able to upload the large file just fine from the XP machine.

I have the following lines coded in the Web.config, and this is allowing larger files to work for our Windows 7 machines.

<httpRuntime maxRequestLength="209715200" enable="true" useFullyQualifiedRedirectUrl="true" executionTimeout="3600" />

...

<requestLimits maxAllowedContentLength="209715200"/>

Any ideas what is happening? By the way I am using version 2011.1.315.40 of Telerik but we experienced the same behavior under the last version of Telerik as well.

ComboBox with load on demand and checkboxes.

I have a ComboBox on my page which is using autocomplete and load on demand to search through a database table containing 50,000 names:

<telerik:RadAjaxPanel runat="server" ID="RadAjaxPanel2">

<telerik:RadComboBox ID="RadComboBox2" runat="server"

Width="300" Height="300" Label="Select people:" EmptyMessage="Type a persons name"

AllowCustomText="true" MarkFirstMatch="True"

DataSourceID="SqlDataSource2" DataTextField="Name"

DataValueField="Name" Filter="Contains"

EnableAutomaticLoadOnDemand="True" EnableVirtualScrolling="true" ItemsPerRequest="15"

/>

</telerik:RadAjaxPanel>

This works fine if I want to select one item however I would like the user to be able to select multiple items, E.g. the user searches for John and is able to select several people called John. It doesn't need to retain the selected items between multiple searches.

If I add in a Checkboxes="True" attribute, the control starts acting strangely. The textbox keeps clearing as I type and the selected items are cleared when I try to post back the page. Is there a way to make this work?

Pushing enter in edit modals brings up another modal

I have an editable RadGrid within a RadAjaxPanel that utilizes modal popups and form templates for editing.

When users try to insert a row and push enter, a second modal will come up for editing a row: Screenshot

We don't want to support users pressing enter to submit the modal anyway (they should just click the save button), so I'm trying to prevent the postback being caused by the enter key being pressed using javascript:

<ClientSettings AllowKeyboardNavigation="False">

<ClientEvents OnKeyPress="BlockEnterKey" />

<KeyboardNavigationSettings AllowSubmitOnEnter="false" />

</ClientSettings>

<script type="text/javascript">

function BlockEnterKey(sender, e) {

if (e.get_keyCode() == 13) {

alert('Blocking Enter KeyPress');

e.set_cancel(true);

e.cancelBubble = true;

return false;

}

</script>

Unfortunately this seems to have absolutely no effect (other than that alert I put in there to make sure it's running).

Any idea as to why I'm unable to block this keypress event?

RadRotator mouse interruption issue on AutomaticAdvance mode

Hello,

I have a radRotator.
Rotator type is "AutomaticAdvance" and ScrollDirection is "Left".
PauseOnMouseOver is "true" (mandatory)

If I move the mouse cursor along with the item scrolling direction before scrolling is not completed,
it stopped at inappropiate position and continue scrolling with that position.
Same thing happen at following demo website.
http://demos.telerik.com/aspnet-ajax/rotator/examples/overview/defaultcs.aspx
I attached the screen capture of RadRotator with above demo.

Please check and let me know how can I solve this problem?

Thanks in advanced

Problem with RadFormDecorator? and CDN

Hi,

I have successfully linked to the local CDN for the Scripts, but I'm having trouble trying to link to a local CDN for the Skin files.

I'm trying to get away from the WebResource.axd and ScriptResource.axd links, because for some of my clients, it gets caught up in their intrusion detection software as bad data, and gets blocked.

in the Web.Config

<add key="Telerik.Skin" value="Office2010Blue" />

<add key="Telerik.StyleSheetManager.TelerikCdn" value="Enabled" />

<add key="Telerik.StyleSheetManager.TelerikCdn.BaseUrl" value="http://www.abc.com/Skins" />

<add key="Telerik.StyleSheetManager.TelerikCdn.BaseSecureUrl" value="https://www.abc.com/Skins" />

<add key="Telerik.ScriptManager.TelerikCdn" value="Enabled" />

<add key="Telerik.ScriptManager.TelerikCdn.BaseUrl" value="http://www.abc.com/Scripts" />

<add key="Telerik.ScriptManager.TelerikCdn.BaseSecureUrl" value="https://www.abc.com/Scripts" />

And here is the first part of the Aspx Master File; notice the RadScriptManager and RadFormDecorator

For the Script includes, I get nice Script requests in the raw HTML (Partial example)

OnClientDropDownClosed for RadComboBox throws javascript error

Hello,

I am getting a JavaScript error when I call my javascript function from the OnClientDropDownClosed client-side event from the RadComboBox control.

The error I get is the following:

JavaScript critical error in (unknown source location)

SCRIPT1009: Expected '}'

My javascript is the following

<script type="text/javascript">

function displaySelectedValues() {

debugger;

var combo = $find("<%# RadComboBox1.ClientID %>");

alert(combo.get_checkedItems().length);

//for (var i = 0; i < dropdown.get_checkedItems().length; i++) {

// var text = dropdown.get_items().get_text();

// label.value = label.value + text;

//}

}

</script>

I use <%# instead of <%= because I get an error from visual studio, but regardless of which one I use I still receive the javascript error mentioned above.

The visual studio error is the following:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

I'm not sure if this is related to telerik or not, but if I have <%= visual studio wont even allow me to get on the page.

My markup code is as follows

<telerik:RadAjaxPanel runat="server" ID="rapConfiguration" LoadingPanelID="ralpConfiguration">

<telerik:RadWindow ID="modalPopup" runat="server" Width="650px" Height="325px" Modal="true" Behaviors="Close">

<ContentTemplate>

<table style="padding:10px;">

<tr>

bunch of td tags

</tr

<tr>

<td style="vertical-align:top;">

</td>

<td style="vertical-align:top;">

</td>

<td style="vertical-align:top;">

<asp:CheckBox id="cbElementValue" runat="server" Visible="false" Text="Check = Yes/True"/>

<telerik:RadCalendar ID="calElementValue" runat="server" Width="200px" RangeSelectionMode="None" EnableMultiSelect="false"></telerik:RadCalendar>

<asp:TextBox ID="txtBoxElementValue" runat="server" Width="200px"></asp:TextBox>

<telerik:RadComboBox ID="RadComboBox1" runat="server" CheckBoxes="true" EnableCheckAllItemsCheckBox="true" Visible="false" Label="Look up values:" OnClientDropDownClosed="displaySelectedValues();">

</telerik:RadComboBox>

</td>

<td style="vertical-align:top;">

<asp:CheckBox ID="chkExpression" runat="server" Visible="false" OnClick="checkExpression(this);"/>

</td>

</tr>

</table>

<div>

<asp:Label runat="server" ID="lblSelectedValues" Text="testing, one, two, three">Selected Values: </asp:Label>

</div>

<div class="bottomRight">

<asp:Button runat="server" ID="btnSubmitValues" Text="Submit Values" OnClick="btnSubmitValues_Click" />

</div>

</ContentTemplate>

</telerik:RadWindow>

</telerik:RadAjaxPanel>

I tried moving the RadComboBox outside the table and I still got the error, I tried not passing in a value to the javascript function and I still got an error, because originally I was passing in "this" to the javascript function from the RadComboBox event property. Such as

OnClientDropDownClosed="displaySelectedValues(this);"
Do you have any advice on how I can get past this error?

After I receive the error and choose to continue through it the control still loads on the page but is unclickable, I can't open the dropdown list or type in the combobox.

Getting value of checked nodes when using sitemap as declarative datasource

Hi guys,
Ultimately, I am trying to build an xml string from the checked nodes in the treeview, though I'm having issues trying to retrieve the text and value fields from checked nodes when I have the treeview control bound to a sitemapdatasource and I was hoping you could help me out.
Thanks in advance!

My code-behind looks like:

StringBuilder pagecfg = new StringBuilder();

pagecfg.AppendLine("<pageconfig>");

IList<RadTreeNode> nodeCollection = rtvSitemap.CheckedNodes;

foreach (RadTreeNode node in nodeCollection)

{

pagecfg.AppendLine(string.Format("<page title='{0}' url='{1}' />",node.Text, node.Value));

}

pagecfg.AppendLine("</pageconfig>");

Where the sitemap file looks like:

<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" enableLocalization="true">

<siteMapNode title="$resources:SiteMapLocalizations,HomePageTitle" url="~/default.aspx" description="$resources:SiteMapLocalizations,HomePageDescription" Expanded="false" />

<siteMapNode title="$resources:SiteMapLocalizations,PartSectionTitle" url="" description="$resources:SiteMapLocalizations,PartSectionDescription" Expanded="true" >

<siteMapNode title="$resources:SiteMapLocalizations,PartPageTitle" url="~/Pages/Production/ProdPart.aspx" description="$resources:SiteMapLocalizations,PartPageDescription" SecAccess="Production" />

</siteMapNode>

</siteMap>

My markup is as follows:

<telerik:RadTreeView ID="rtvSitemap" runat="server" DataSourceID="dsSiteMap" CheckBoxes="true" MultipleSelect="true" CheckChildNodes="True" DataModelID="Title" DataNavigateUrlField="Url">

<DataBindings><telerik:RadTreeNodeBinding Expanded="true" TextField="title" ValueField="url" /></DataBindings>

</telerik:RadTreeView>

Fileexplorer error with ScriptManager on different Page

Good day all,

we're trying to use a FileExplorer in a simple context: we require that the FileExplorer be defined in an user control. This user control is included in a site page that references a master page. The master page includes a Script manager.

When accessing the page that includes the user control with the fileexplorer, however, we receive the following error:

"The control with ID 'ajaxPanel' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it."

There's no 'ajaxPanel' component both in our page nor in our code.
The component is declared as thus inside the page:
<telerik:RadFileExplorer runat="server" ID="RadFileExplorer1"></telerik:RadFileExplorer>

When moving the component out from the user control into any web form using the masterpage, the fileexplorer works.
The user control references the masterpage using <%@ Reference Control="~/MasterPage.master"%>

It would seem that the radfileexplorer component is unable to dereference the scriptmanager inside the page. We've tried
RegisterWithScriptManager="false"
but this setting has no effect on the error.

So, how can we manually or dynamically assign an intended radscriptmanager to the radfileexplorer?
