radnumerictextbox cannot OnKeypress with Enter key on IE, Chrome

Hi everybody,
I have issue with Enter key pressed on radnumerictextbox. This key is not handled by OnKepPress event in clientevents with IE9 and Chrome 23 (only work fine in firefox)
Is there any workaround to have Enter key handled by RadNumericTextBox in IE and Chrome?
I use Telerik version 2012.1.411.35

--------Control-------

<telerik:RadNumericTextBox ID="zoomNumber" runat="server" Height="25" Type="Number"
AutoPostBack="False" ShowSpinButtons="True" Width="55px" MaxValue="400" MinValue="25"
Value="100" Enabled="True" ReadOnly="False">
<NumberFormat DecimalDigits="0"></NumberFormat>
<IncrementSettings Step="8" InterceptMouseWheel="False"></IncrementSettings>
<EnabledStyle ForeColor="#FFFFFF" BackColor="#215C7A" BorderColor="#333333" HorizontalAlign="Right" />
<ClientEvents OnValueChanged="zoomChanged" OnValueChanging="zoomChanging" OnKeyPress="onNumericKeyPress"></ClientEvents>
</telerik:RadNumericTextBox>

---------Javascript-------------

function onNumericKeyPress(sender, args) {
if (sender != null) {
if (args.get_keyCode() == 13) {
sender.set_value(parseFloat(sender.get_editValue()));
}
var c = args.get_keyCode();
if ((c < 48) || (c > 57))
args.set_cancel(true);
}
}

Best regards,
Ba

About FileBrowserContentProvider

Hi,

my approach is to backup files when a user loads up a file which already exists in the filesystem.
I took a look at the online documentation as well as in the DBContentProvider - but without meaningful documentation it would really mean a lot of time to figure out what parameters to pass where.

And if I see constructors with 7 parameters like for DirectoryItem it is pretty hard to develop something without documentation.
And by the way - the example (DBContentProvider) deals with slashes - as well for url's (normal) as for filepaths (where I would use backslashes for the file system).
A lot of parameter are simply give as string.Empty...

So the idea of writing an own provider is good - and since the FileExplorer does not offer server methods like the RadUpload to handle uploading (storing) files it seems to be the only possible method.
BUT - due to the poor documentation it is impossible for me to build such a thing within a timeframe that seems to be acceptable.

Is there any sample for a filesystem provider?

The approach is nothing less or more than:
If a file gets deleted - create a backup copy.
If a file will be overwritten - create a backup copy.

In http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/select-a-file-in-code.aspx#792727 someone asked a member to provide code in the Code Library - but the Library does not even have a section for FileExplorer.

Regards

GridSettingsPersister saving to SQL.

I am trying to save setting to SQL. It works fine until I recompile and then it falls apart.

Does anyone have an example of the GridSettingsPersister that uses the BinaryFormatter instead of the LosFormatter?

I am still unable to get the BinaryFormatter to work. Has anyone been able to get the GridSettingsPersister to work with the BinaryFormatter?

public override string ToString()

{

//LosFormatter formatter = new LosFormatter();

BinaryFormatter formatter = new BinaryFormatter();

//using (StringWriter writer = new StringWriter())

using (MemoryStream writer = new MemoryStream())

{

formatter.Serialize(writer, this);

string arr = writer.ToString();

return arr.ToString();

}

/// <summary>

/// Gets the GridSettingsCollectionInstance from its serialized string data

/// </summary>

/// <param name="data">The object as serialized string data</param>

public static GridSettingsCollection LoadFromSerializedData(string data)

{

//LosFormatter formatter = new LosFormatter();

BinaryFormatter formatter = new BinaryFormatter();

byte[] arr = System.Text.Encoding.ASCII.GetBytes(data);

MemoryStream stream = new MemoryStream(arr);

//return (GridSettingsCollection)formatter.Deserialize(data);

return (GridSettingsCollection)formatter.Deserialize(stream);

}

RadUpload returns empty uploadedfiles collection

Hi all,

I have a page that has a radupload control on it. In the code behind we check to make sure the uploadedfiles collection has something in it before we attempt to process the uploaded file.

This works on every system in our dev environment except for one. We have tried copying the directory tree between systems, completely wiping the directory and starting from scratch, and checking every setting we can think of.

It does not use an AJAX post-back, the app is set to run Full Trust, and we are not changing the masterpageID in the init.

Any ideas? banging my head against a wall on this one.
