Save image in RadImageEditor

How do I save the image after I have made changes using asp:button OnClick="xxx" (post back) to the database?

I have several controls (asp:Panel, asp:Label....) that I need to update after I change the image....

I'm reading my picture using OnImageLoading

    Protected Sub RadImageEditor1_ImageLoading(sender As Object, args As ImageEditorLoadingEventArgs)

        Dim MyConnection As New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConn").ConnectionString)

        Dim MyCommand As New SqlCommand("select ID, imagedata from bildbank_data where ID = @ID;", MyConnection)

        MyCommand.Parameters.Add(New SqlParameter("@ID", SqlDbType.Int, 4))
        MyCommand.Parameters("@ID").Value = lblPickUpId.Text

        If MyConnection.State = ConnectionState.Closed Then
            MyConnection.Open()
        End If

        Dim dr1 As SqlDataReader = MyCommand.ExecuteReader
        If dr1.Read Then
            If Not dr1("imagedata") Is DBNull.Value Then
                Dim imagedata As Byte() = dr1("imagedata")
                Dim s As New MemoryStream(imagedata.ToArray())
                Dim img As New Telerik.Web.UI.ImageEditor.EditableImage(s)

                args.Image = img
                args.Cancel = True
            End If
        End If

        dr1.Close()

        MyCommand.Dispose()

Hello telerik,

This is my first time using the telerik. I want to know how to add the following judgments in JavaScript or events. And also remove the image which does not fit the criteria at the same time.

For example, I need type in a text box '123' and upload an image called '123.jpg', then it is allowed to upload, because '123'='123'.But if I type in a text box '123' and upload an image called 'abc.jpg', it is not allowed to upload, because '123'<>'abc', then auto remove the image and reselect. how can I do it, please help me.

the following is my code.

<telerik:RadTextBox ID="txtContainer" runat="server" OnTextChanged ="txtContainer_TextChanged" AutoPostBack ="true" ></telerik:RadTextBox>

<telerik:RadAsyncUpload RenderMode="Lightweight" runat="server" ID="AsyncUpload1" AllowedFileExtensions="jpeg,jpg,gif,png,bmp" OnFileUploaded="RadAsyncUpload1_FileUploaded1" OnClientValidationFailed="onClientValidationFailed" MaxFileInputsCount="1" > </telerik:RadAsyncUpload>

function onClientValidationFailed(sender, args) {

$telerik.$(".ruCancel").parent().remove();
alert("Allowed files extension is jpeg,jpg,gif,png,bmp");
sender.addFileInput();
}

Simply putting combobox on my page increases render time by FIVE seconds in IE6. What's the dealio?

I have a combobox on my form with load on demand.

Simply putting that combo box on my page has turned a page that was pretty instantaneous to a page that takes five seconds to load.

If firefox it works like a champ. In IE7, I get the five second delay.

Do you guys have an IE7 fix for this issue?

EDIT: I meant IE7. I can't change the post title...
