I used a Radpanel embedded with RadMultiPage. I used a javascript to perform some computation, values needs to be computed when data is retrieved from the database. This causes a postback on the "panel" and the values computed by the javascript is cleared. I need to call the javascript when the postback occur. I placed a call on the page load event. This didnt work, what can I do?

Thanks in advanced

[Solved] RadBinaryImage - The provided binary data may not be valid image or may contains unknown header

Hi All:

I have loaded my db column declared as follows:
[Thumbnail] [varbinary](max) NULL

I have loaded the column as follow:

Dim _pdfStream As FileStream = Nothing

Dim _fileName As String = "C:\Src\Proj\trunk\Data\2010-05-May-Cover.pdf"

If My.Computer.FileSystem.FileExists(_fileName) Then

_pdfStream = New FileStream(_fileName, FileMode.Open, FileAccess.Read)

Dim _length As Integer = CInt(_pdfStream.Length)

Dim _contents(_length) As Byte

_pdfStream.Read(_contents, 0, _length)

_pdfStream.Close()

' ... insert _contents into db

End If

I reference as follows:

<asp:FormView

id="mImageFormView" runat="server"

DataSourceID="mImageDataSource">

<ItemTemplate>

<telerik:RadBinaryImage ID="rbiThumbnail" runat="server" Width="180px" Height="220px"

DataValue='<%# Eval("Thumbnail") %>' AlternateText='No image'

/>

</ItemTemplate>

</asp:FormView>

I am getting the following:
The provided binary data may not be valid image or may contains unknown header

Anything wrong?
How do I verify that the image data is stored correctly?

[Solved] Style Collision: Using 2 Custom Styles

Telerik Developers,

I have 2 Menu Controls Menu A | Menu B. I'm using both of them on the same page. I've created 2 Custom Styles for each of them using the Visual Style Builder and when I add the CSS for Menu B to my CSS Folder, Menu A Text color and margins change as they're both responding to ".RadMenu". Why didn't all my styles change to .RadMenuX? Is this suppose to happen?

Update/Insert/Delete in Hierarchy

I have an extra RadGrid as Detail Table which needs to be editable (update, insert, delete).

I thought that DetailTable contains the needed Event Handlers for that but obviously i was wrong.

So now, i don't know how do i do that. I am using RadGrid1_DetailTableDataBind event to bind the nested Grid to Datatable:

Dim dataItem As GridDataItem = CType(e.DetailTableView.ParentItem, GridDataItem)

If e.DetailTableView.Name = "Payments" Then

Dim PurchaseID As Integer = Convert.ToInt16(dataItem.GetDataKeyValue("SaleID").ToString)

e.DetailTableView.DataSource = PurchasesAccess.GetPayments(PurchaseID)

End If

However i still don't know how do i call UpdateCommand, InsertCommand and DeleteCommand for the grid which is detail table.

I am not using SqlDataSource objects and such. Rather i am using classes and stored procedures.

Thanks

Master/Content Pages and ClientIDs

I am running into an issue picking up control clientIDs when it comes to master/content pages. For example, using $find("<%= controlName.ClientID %>") in a single page would allow me to access the controls id. However, if I place the same code in a content page, I get a 'null' error. It cannot find the control. Below is the content page I am attempting to access a controls ID. Any help would be appreciated.

<%@ Page Title="" Language="C#" MasterPageFile="~/MES.master" AutoEventWireup="true" CodeBehind="timesheet.aspx.cs" Inherits="ESPS.Timesheet.timesheet" %>

<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

<asp:ScriptManagerProxy runat="server"></asp:ScriptManagerProxy>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript">

var btn = $find("<%# rBtnTest.ClientID %>");

alert(btn);

</script>

</telerik:RadCodeBlock>

<div style="background-color: Blue;">

<telerik:RadButton runat="server" ID="rBtnTest" Text="Test" />

</div>

</asp:Content>



Disregard this post, I have figured the out the problem.

Loading Panel not showing consistently

We have a page that primarily features a RadScheduler control. Certain actions fire an Ajax request and we refresh the Scheduler in these cases. The Scheduler always refreshes properly, but the Loading Panel only shows occasionally. I haven't been able to determine a set pattern in terms of when it shows/doesn't show yet. I believe that I have the controls set up properly. Has anyone else ran into an issue like this before? I have tried to set up events for RequestStart and RequestEnd which manually hide/show the loading panel and this works a little better, but still not consistently. Any tips would be appreciated! Below is a sample of the code that I'm using.

    <telerik:RadAjaxManager ID="ajxmgr" runat="server" OnAjaxRequest="ajxmgr_AjaxRequest"
        UpdatePanelsRenderMode="Inline">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="ajxmgr">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="rdScheduler" LoadingPanelID="lpMdl" />
                    <telerik:AjaxUpdatedControl ControlID="control1" />
                    <telerik:AjaxUpdatedControl ControlID="dtPckr" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="rdScheduler">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="RadCalendar1" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
        <ClientEvents OnRequestStart="RequestStart" OnResponseEnd="ResponseEnd" />
    </telerik:RadAjaxManager>
    <telerik:RadAjaxLoadingPanel ID="lpMdl" runat="server" Transparency="20" BackColor="#E0E0E0"
        IsSticky="false" InitialDelayTime="100">
        <div class="ldpnl">
            Please Wait...
            <br />
            <img src="images/icons/ajax-loader2.gif" alt="loading..." style="padding-top: 15px;" />
        </div>
    </telerik:RadAjaxLoadingPanel>

Thanks!

Image Manager Not Displaying Images if filename has certain characters

Hello,

We have added the ImageManager in our Rad Editor. It's working fine, except when we try to upload images with certain 'invalid' characters (ex. '#'). Is there any work around for this? The image is not displayed when we try to insert it in the rad editor.

Thanks

Editor
