Greetings,

I'm not sure if this is a reported bug yet or not, however, my company uses version the following version of Telerik Controls:

Telerik.Web.UI_2011_2_809

Currently we experience an issue with the following browser/operating system combo: IE8 and Win7 Ultimate.

The issue is when using the RadEditor's image manager, when a user tries to upload an image, the Select button is missing. If you click where it should be, it works. Once more, once an image is picked, the text does not show up in the text box for it. This issue does not show up in any other browser or operating system combo. It was proven to be a bug due that it was on your site originally, however, it may have been corrected since the newer version has come out. Just not sure if it is a bug still or not. Thanks.

Kindest Regards,
Chad Johnson

Dock order changed

Hi all:
I use dockzone to load docks in. each dock is user control. I have a dropdownlist which user select and then it will load the existing dockstates

the issue now is that the dock order mess up after I switch dropdownlist selection. example: for dropdownlist, it has value "a" and value "b". when I select value "A", it will load dockstate1 and then when I select value "b", it will load dockstate2 from database. now I select value "A" and the dockstate1 is loaded and docks are ordered correctly. then I change some dock's postion by drag and drop. every thing works fine and dock index saved to database with correct number. then I select value "b" so dockstate2 is loaded. Then I reselect value "a", the dockstate1 is reloaded from database with correct index but the dock orders are changed. they order with the Alphbetic instead of the previous order. I found the dock/state index value changed after RadDockLayout1.GetRegisteredDocksState() is called. why the dock index change ? Please see rough codes

any suggestion?

Thanks
Helena

Protected Sub RadDockLayout1_LoadDockLayout(ByVal sender As Object, ByVal e As DockLayoutEventArgs) Handles RadDockLayout1.LoadDockLayout

'Populate the event args with the state information. The RadDockLayout control

' will automatically move the docks according that information.

'If isNeedReload Then

Dim state As DockState

Dim intIndex As Integer

Dim serializer As Script.Serialization.JavaScriptSerializer = New Script.Serialization.JavaScriptSerializer()

Dim stateList As List(Of DockState) = Me.RadDockLayout1.GetRegisteredDocksState()

If Not stateList Is Nothing Then

For Each state In stateList

e.Positions(state.UniqueName) = state.DockZoneID

e.Indices(state.UniqueName) = state.Index

Next

End If

End Sub

Protected Sub RadDockLayout1_SaveDockLayout(ByVal sender As Object, ByVal e As DockLayoutEventArgs) Handles RadDockLayout1.SaveDockLayout

Dim strMethodName As String = Me.strClassName & "RadDockLayout1_SaveDockLayout"

Try

Dim stateList As List(Of DockState) = Me.RadDockLayout1.GetRegisteredDocksState()

//on stateList , the dock index changed ????

End sub

Protected Sub RadComBoxView_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles RadComBoxView.SelectedIndexChanged

Dim strMethodName As String = Me.strClassName & "RadComBoxView_SelectedIndexChanged"

Try

If Not Me.RadComBoxView.SelectedItem Is Nothing Then

'reset SystemUserWidgetID

SystemUserWidgetID = -1

Me.CurrentViewTypeID = Me.RadComBoxView.SelectedItem.Value

'need to load WidgetState based on viewid

Me.GetUserWidgetState()

CreateWidgetStates()

End if

End Sub

Hi,

I have a radcombobox declared like this:

<telerik:RadComboBox ID="RadComboBox1" Runat="server" Width="300"

AppendDataBoundItems="True">

<ItemTemplate>

<div class="item c1"><asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("URLImage") %>' /></div>

<div class="item c2"><%# Eval("Imagename") %></div>

</ItemTemplate>

</telerik:RadComboBox>

RadComboBox1.DataSource = getimages()

Function getimages() As List(Of Fotos)

Dim ofile, foto

Dim ObjetoFSO = Server.CreateObject("Scripting.FileSystemObject")

Dim ObjetoFolder = ObjetoFSO.GetFolder(Server.MapPath("../images/works"))

Dim ofotos = New List(Of Fotos)

For Each ofile In ObjetoFolder.Files

Am I doing something wrong? Where is my mistake?

Thanks!

even handler for item clicked?

I have a combo box with items that allow a user to select a built-in date range or specify a custom date range (see attached ff.jpg for example). When an Item is selected, I postback and perform various funciions depending on the selected date range. If the selected Item is "Custom dates..." or "Custom to date...", I display a tooltip server-side which allows users to enter a custom date range. Everything works fine... however, if the user enters a custom date range by selecting "Custom dates...", they cannot then go and alter their date range because they can't re-select "Custom Dates...". It is already selected. They have to choose another item in the list and then select "Custom dates...". Since the SelectedIndexChanged event is not fired if you select an item which is already selected, Is there some way to handle an item_clicked, or similar event instead of SelectedIndexChanged server-side? Ideally, I would retrieve the value of the item clicked in this event handler and only perform the necessary functions if it corresponds to the "Cusomt Dates..." or "Custom to date..." items. Otherwise, would perform my functionality in the SelectedIndexChanged server-side handler.

[Solved] Controlling table widths when Exporting PDF

I need control of the table columns widths when exporting to PDF from the RadEditor. I followed instructions from http://www.telerik.com/help/aspnet-ajax/grid-pdf-export.html (on exporting HTML to PDF). I followed the instructions under 'Exporting HTML Tables' to test controlling table widths. I copied and pasted the following into my RadEditor and exported the PDF and it does not work. I suspect that it may not be working because of the automatic corrections that RadEditor makes (I disabled 2 filters but it did not correct it).

1) How do I disable this auto correction?
2) Is the html table below correct for controlling column widths in PDFs?

Please see source:

ASPX Page:

<%@ Page Language="VB" %>

<%@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat="server">

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)

RadEditor1.ExportToPdf()

End Sub

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)

If IsPostBack = False Then

RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.DefaultFilters)

RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertToXhtml)

End If

End Sub

</script>

<html xmlns="http://www.w3.org/1999/xhtml">

<body>

<form id="form1" runat="server">

</Content></telerik:RadEditor>

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

</div>

</form>

</body>

</html>

Table example that I pasted directly off of help link:

<table width="300px">

<colgroup>

<col style="200px" />

<col style="20px" />

</colgroup>

<tr>

<td>Cell1</td>

<td>Cell2</td>

</tr>

</table>

After I paste the above HTML in the HTML section of the RadEditor, I clicked back to Design, then back to HTML and it changes the code to this:

<table style="width: 0px;" width="300px">

<colgroup>

<col style="">

</colgroup>

<tbody><tr>

<td>Cell1</td>

<td>Cell2</td>

</tr>

</tbody></table>

Loading image from Entity Framework

I have an image within the itemtemplate of a RadListView. I'm populating several of the controls within the template on the ItemDataBound event for the ListView with the Entity Framework. I'm new to the Entity Framework so need some help in figuring out how to populate the RadBinaryImage control.

The method I have for retrieving the image is this:

public static byte[] GetAccommodationMainImage(int accomID)

{

byte[] image = null;

using (var myEntity = new MyEntity1())

{

var photoRecord = (from accom in myEntity.WTO_Photos

where accom.accom_id == accomID

&& accom.in_use_as_main == true

select accom).First();

image = photoRecord.image;

}

return image;

}

AppointmentDataBound fires twice when changing views

I have 4 appointments that I am loading from a custom datasource(datatable) into the RadScheduler control.

When the page first loads the AppointmentDataBound event occurs 4 times. (once for each appointment)

When I change VIEWS (from MONTH to WEEK or vice versa) that the AppointmentDataBound event occurs 8 times.
Double.

Am I doing something wrong? Is this by design?
Is there anything that I can do to stop it from doing this?

Thanks in advance for any guidance.

Combo is clearing the text when using Checkbox and LoadOnDemand

Hi !!
The scenario is this:

RadComboBox with LoadOnDemand="True".
The user starts inputing some text, and the combo load the results when the ItemRequestTimeout is reached.
The input text is still in the combo, even before the combo load the results, so the user can continue to input more text, or change parts of it, etc. The combo keeps making the searches and everything works perfect.

The problem is that when I enable the CheckBoxes="True", everytime the combo makes a search to load the results, it clear the user's inputed text, and the user cannot keep inputing more text.

Can i keep the user's text in the combo with CheckBoxes = true ?

Thank's

Accessing RadTabStrip ID from associated ContentURL page

Hi,
I have a main page (default.aspx) with a RadTabStrip, and associated RadMultiPage and RadPageViews. The RadPageViews use ContentURL to load their content. On the first ContentURL page I have a button which when clicked should cause the RadTabStrip's second tab to be selected. This is somewhat similar to the TabStrip/Wizard demo program. My problem is in the first ContentURL page's button clicked callback I can't get the reference to the RadTabStrip control using FindControl - FindControl returns null. Is what I'm trying to do possible?

Thanks,
Mike

Showing a table and plotted area in one chart

Hi all,

I want to display a table summarizing some information above the plotted area. Can I make a table in RadChart?

I want to do it because I have a limitation that I have to export/save the chart as a single JPG, so can't separate the chart and table.

Any help will be highly appreciated.
