RadWindow repositions after centering it.

Hi,

I have a page with a radgrid, scrolled down to a specfic row. I click on the row and make my window visible by setting the "VisibleOnPageLoad"-property to True and I center it using the "OnClientAutoSizeEnd"-clientevent.
The window is positioned correctly at this moment but is then automatically repositioned lower on the page.
Any ideas which setting could be causing this?

This is the definition of my window:

<telerik:RadWindow ID="wdwDetail" Modal="true" Skin="Telerik" Width="800px" AutoSize="true" AutoSizeBehaviors="Height" OnClientAutoSizeEnd="OnClientShowCenterOnly" runat="server" VisibleOnPageLoad="false" VisibleStatusbar="false" IconUrl="~/img/favicon.ico" ShowContentDuringLoad="true" Title="Detailed Info" DestroyOnClose="false" EnableShadow="true" Behaviors="Close">

<ContentTemplate>

...

</ContentTemplate>

</telerik:RadWindow>

Note that it isn't defined inside a RadWindowManager as I want to use a asp updatepanel inside it.

Thanks in advance,

Wim

Maps

Is there any plans for a asp.net ajax map control? I know google maps is widely used but it would be nice to have something similar to the silverlight map control in asp.net.

Radwindow showing javascript error

Hai,

I have a Radwindow like this :

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false"
                                                        ReloadOnShow="true" runat="server" Skin="Web20" Style="z-index: 20002" >
                                                        <Windows >
                                                            <telerik:RadWindow ID="RadWindowPopup"
                                                                EnableShadow="true" DestroyOnClose="true" Visible="true"
                                                                Behaviors="Resize, Close, Maximize"
                                                                VisibleOnPageLoad="false" runat="server" Title="Local Item Request" Skin="Web20">
                                                            </telerik:RadWindow>
                                                        </Windows>

                                                    </telerik:RadWindowManager>

In Code behind, I have called this radwindow like this :

if (!ClientScript.IsStartupScriptRegistered("popupWindow"))
                     System.Web.UI.ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "popupWindow", "showWindow();", true);

showWindow() javascript is

function showWindow() {

var varMealOrderID = document.getElementById('ctl00_CphMaster_hidMealOrderId').value;

var oWnd = radopen('FKMS_CTRL_Local_Item_Request.aspx?MealOrderId=' + varMealOrderID + '&popup=true' + '&Mode=NEW', 'RadWindowPopup');

oWnd.setSize(1100, 750);

oWnd.moveTo(75, 50);

}

This code works fine in my local development computer. But When I hosted in a server, it is showing the following javascript error in the radopen portion of showWindow() method.

Microsoft JScript runtime error: Object doesn't support this property or method

Please help me.

how to display file content with tooltip

Hi all:
I try to display the file ( txt, image , PDF , word..etc format) using tooltip. ( just like the sameple
http://demos.telerik.com/aspnet-ajax/tooltip/examples/targetcontrolsandajax/defaultvb.aspx)

the issue is that when I mouse over the record, I got the following error : "RadTootipManager response error. ...the message received from server could not parsed..."

what I did is to read the files then use the response.write to generate the file content.please see code below:

'on parent page which has tooltip with it

Private Sub UpdateToolTip(ByVal elementID As String, ByVal panel As UpdatePanel)

Dim ctrl As Control = Page.LoadControl("WidgetControls/WidgetSupportDocument.ascx")

panel.ContentTemplateContainer.Controls.Add(ctrl)

Dim details As WidgetSupportDocument = DirectCast(ctrl, WidgetSupportDocument)

details.SupportDocumentID = elementID

details.DisplayData()

End Sub

on WidgetSupportDocument.ascx control:

Public Sub DisplayData()

Dim dsData As DataSet

Dim strFileName As String

Dim byteData() As Byte

Dim strDocumentType As String

Dim arrSplit() As String

'load data from database

dsData = LoadData(Me.SupportDocumentID)

byteData = CType(dsData.Tables(0).Rows(0).Item("FileContent"), Byte())

arrSplit = Split(dsData.Tables(0).Rows(0).Item("Filename").ToString, ".")

intLastValue = arrSplit.Length

strDocumentType = arrSplit(intLastValue - 1)

SetControlData(strDocumentType, byteData)

End Sub

Private Sub SetControlData(ByVal strDocumentType As String, ByVal byteView() As Byte, Optional ByVal strFileName As String = "")

Dim strContentType As String = String.Empty

Select Case UCase(strDocumentType)

Case "HTML", "HTM"

strContentType = "text/HTML"

Case "BMP"

strContentType = "image/BMP"

Case "JPG"

strContentType = "image/JPEG"

Case "GIF"

strContentType = "image/GIF"

Case "PDF"

strContentType = "application/pdf"

Case "XLS"

strContentType = "application/vnd.ms-excel"

Case "DOC"

strContentType = "application/msword"

Case "TXT", "LOG"

' .txt file (such as a report tab delimited export) should open inline rather then directly in the browser

If strFileName = "" Then

strFileName = "ViewDocument.txt"

End If

With Response

.ClearContent()

.ClearHeaders()

strContentType = "text/unknown"

.AddHeader("Content-Length", CType(byteView.Length, String))

.AddHeader("Content-Disposition", "inline; filename=" & strFileName)

End With

Case Else

End Select

If strContentType.Length > 0 Then

With Response

.Clear()

.ContentType = strContentType

.BinaryWrite(byteView)

.Flush()

End With

Else

Response.Write("<font color='red'>The selected attachement cannot be displayed. </font>")

End If

End Sub

Thanks
Helena

RadBinaryImage throws error on production server not on dev

Hi,

We are using Q3 2010 and have a RadImage control that is throwing the following error - but only on production.

Exception information:

Exception type: ArgumentException

Exception message: The provided binary data may not be valid image or may contains unknown header

If I debug the same image in development, no errors are displayed/thrown. Our production environment and development operate in integrated mode and have the following handler entry

<add name="Telerik_Web_UI_WebResource_axd" verb="*" preCondition="integratedMode" path="Telerik.Web.UI.WebResource.axd" type="Telerik.Web.UI.WebResource" />

The error only occurs for a handful of images, but when it happens, it brings the entire page down. How can I test whether the data coming from sql is a valid image and catch this condition ahead of time? I have a try catch surrounding everything, but it does not appear to have an impact. I am guessing that the image control is outputting content that ends up corrupting the html output. Any thoughts welcome.

Missing controls in designer View

My issue is that when I modify my aspx page, ranging anything from adding a div tag to a simple br tag, it will result in the design view hiding all controls of my page, and it's master page. The only thing that would remain visible is the main master page.

My setup:

MenuMaster.master
-> NavBar.master
-> default.aspx

I am running VS2010 version 10.0.303019.1 with RadControls for ASP.NET AJAX version 2011.1.519
