Questions on UI for ASP.NET AJAX Forum

Hi,

I have a problem trying to get the contents of a RadEditor located inside a User control through AJAX. The main page has a Radstrip with a multipage and each pageview has attached an instance of the User control with the editor and a button.

When the User control is created from code behind, some default contents are set from the main page to the Editor and it's working properly. But, if we change that text and we call a postback with AJAX, I cannot get the new value.

I am not sure how to proceed to get new values...

thanks.

The User Control:

<telerik:RadEditor ID="RadEditor1" runat="server" Width="100%" BorderStyle="None" EditModes="Design" ContentAreaCssFile="~/css/EditorContentArea.css" ContentAreaMode="iframe">

<CssFiles>

<telerik:EditorCssFile Value="~/css/EditorContentArea.css" />

</CssFiles>

<Tools>

<telerik:EditorToolGroup Tag="MainToolbar">

<telerik:EditorTool Name="AjaxSpellCheck" />

<telerik:EditorTool Name="FindAndReplace" />

<telerik:EditorSeparator />

<telerik:EditorSplitButton Name="Undo">

</telerik:EditorSplitButton>

<telerik:EditorSplitButton Name="Redo">

</telerik:EditorSplitButton>

<telerik:EditorSeparator />

<telerik:EditorTool Name="Cut" />

<telerik:EditorTool Name="Copy" />

<telerik:EditorTool Name="Paste" ShortCut="CTRL+V" />

</telerik:EditorToolGroup>

<telerik:EditorToolGroup Tag="Formatting">

<telerik:EditorTool Name="Bold" />

<telerik:EditorTool Name="Italic" />

<telerik:EditorTool Name="Underline" />

<telerik:EditorSeparator />

<telerik:EditorSplitButton Name="ForeColor">

</telerik:EditorSplitButton>

<telerik:EditorSplitButton Name="BackColor">

</telerik:EditorSplitButton>

<telerik:EditorSeparator />

<telerik:EditorDropDown Name="FontName">

</telerik:EditorDropDown>

<telerik:EditorDropDown Name="RealFontSize">

</telerik:EditorDropDown>

</telerik:EditorToolGroup>

</Tools>

<Content>

</Content>

</telerik:RadEditor>

<div style="float:left;">

<telerik:RadSpell ID="RadSpell1" runat="server" ControlToCheck="RadEditor1" ButtonType="PushButton" AllowAddCustom="true" CssClass="floatL" />

<telerik:RadButton ID="RadButton1" runat="server" Text="Save" Height="22px" />

</div>

User Control Code behind:

Imports Telerik.Web.UI

Public Delegate Sub RadButton1_Click(sender As Object, e As System.EventArgs)

Public Class productAttributesEditor

Inherits System.Web.UI.UserControl

Public Event SaveClick As RadButton1_Click

End Get

Set(value As RadEditor)

End Set

End Property

Public Property SpellSingleLanguage() As String

Get

Return singleLang

End Get

Set(value As String)

singleLang = value

End Set

End Property

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

If Not Page.IsPostBack Then

RadEditor1.Modules.Clear()

RadEditor1.Languages.Clear()

RadEditor1.SpellCheckSettings.AllowAddCustom = True

RadEditor1.SpellCheckSettings.SpellCheckProvider = SpellCheckProvider.PhoneticProvider

If String.IsNullOrEmpty(singleLang) Then

Using ctx As New MyLovelyFood_DynamicStocksEntities()

Dim langs = From a In ctx.aux_languageList Where a.Published = True And a.SpellEnabled = True Select a.LanguageCulture, a.Name, a.PrimaryLang Order By PrimaryLang

For Each row In langs

RadEditor1.Languages.Add(New SpellCheckerLanguage(row.LanguageCulture, row.Name))

Next

End Using

Else

RadEditor1.SpellCheckSettings.DictionaryLanguage = singleLang

End If

End Sub

Protected Sub RadButton1_Click(sender As Object, e As EventArgs) Handles RadButton1.Click

RaiseEvent SaveClick(Me, e)

End Sub

End Class

Default page:

' Prepare text editor

' For each Tab, create a new Editor...

Private Sub RadTabStripIngredients_TabDataBound(sender As Object, e As RadTabStripEventArgs) Handles RadTabStripIngredients.TabDataBound

Dim pageView As New RadPageView()

pageView.ID = e.Tab.Value

RadMultiPageIngredients.PageViews.Add(pageView)

End Sub

Private Sub RadMultiPageIngredients_PageViewCreated(sender As Object, e As RadMultiPageEventArgs) Handles RadMultiPageIngredients.PageViewCreated

editorControl = LoadControl("~/common/AttributesEditor.ascx")

editorControl.ID = e.PageView.ID & "_userControl"

Using ctx As New DynamicStocksEntities()

Dim langCulture = From a In ctx.aux_languageList Where a.Id = e.PageView.ID Select a.LanguageCulture

editorControl.SpellSingleLanguage = langCulture.FirstOrDefault

End Using

e.PageView.Controls.Add(editorControl)

AddHandler editorControl.SaveClick, AddressOf SaveEditor

End Sub

Private Sub SaveEditor(ByVal sender As Object, ByVal e As EventArgs)

Dim editorObj As productAttributesEditor = TryCast(sender, Object)

Dim content As String = TryCast(editorObj.RadEditor, RadEditor).Text

MsgBox(content) ' >>>> ERROR, WE JUST RECEIVE THE INITIAL VALUE INSTEAD OF THE MODIFIED VERSION

' DO SOMETHING

End If

Ajax broken after upgrade

Dear Telerik,

We've been happily using your RadAjax controls from the 2011.2.712.35 build for the past 2 years, but this week it was time to upgrade the build version, mainly in our hope to deal with IE10 woes. We're now running the 2013.1.403.35 build on our SharePoint components. The upgrade mainly went smooth, minus the calendar component. None of the Ajax functionality is working. I've setup a simple page to demonstrate the failure. Is there anything that I need to make sure is present in my code? Maybe you can suggest a place to start looking?... I'm running out of ideas. Any help is appreciated!

broken calendar: http://2010test.corasworks.net/df/public/SitePages/calendar.aspx
working grid: http://2010test.corasworks.net/df/public/SitePages/grid.aspx
working tree view: http://2010test.corasworks.net/df/public/SitePages/tree%20view.aspx

Thank you,

Dasha.

Grid with selected rows NOT highlighted

Hi,
I would like to use row selection but don't want the row to be highlighted in any way - just use the GridClientSelectColumn checkbox to show the selection. How can I turn the highlighting off?

ZWSP inserted into html in chrome

for v2013.1.220.40

While using the RadEditor in Chrome, a zero width space () is inserted under some circumstances. For example, starting with a blank editor, if you click into the editor, change the font size, click back into the editor and type "test", a zwsp is inserted between the end of the font tag and "test". The problem is when the content is saved to the database, it is saved as a question mark, which is far from ideal. I do not experience this behavior in IE.

Is there a way to prevent the insertion of the zwsp character?

Fill Checkboxlist on Show of radwindow

What I have is a linkbutton with a command name on myradgrid to call my radwindow. So what I need to do is populate the checkbox list that sits in myradwindow on the click of this linkbutton, to populate the checkbox list and see if anything exists check the boxes if not check nothing.

Right now just trying to figure how I can get the checkboxes to populate. After this I will need to pass a value to either populate the list with checkboxes or not depending if saved in DB.

<telerik:RadWindow ID="RadTeams" runat="server" Width="500px" Height="250px" Enabled="true" Modal="true" VisibleTitlebar="false" VisibleStatusbar="false" CssClass="CentTable">

<ContentTemplate>

<table class="CentTable">

<tr>

<td style="text-align:center">Please Pick Teams to Assign to Region</td>

</tr>

<tr>

<td style="height:5px" ></td>

</tr>

<tr>

<td>

<asp:CheckBoxList ID="cbTeams" runat="server" AutoPostBack="false" RepeatDirection="Horizontal" RepeatColumns="3" TextAlign="Right"></asp:CheckBoxList>

</td>

</tr>

<tr>

<td style="text-align:center">

<asp:LinkButton ID="lnkSubmit" runat="server" Text="Submit"></asp:LinkButton>

<asp:LinkButton ID="lnkCancel" runat="server" Text="Cancel"></asp:LinkButton>

</td>

</tr>

</table>

</ContentTemplate>

</telerik:RadWindow>

<telerik:GridTemplateColumn>

<ItemTemplate>

<asp:LinkButton ID="lnkAssign" runat="server"

CommandArgument='<%# Bind("strRegionCode")%>' Text="Assign Teams" CommandName="Assign" OnClientClick='<%# String.Format("addAdminWin({0}, {1}); return false;", Eval("intRegionID"), 2)%>'></

asp:LinkButton>

</ItemTemplate>

</telerik:GridTemplateColumn>

Upload a lot of files

Hi,
We have a requirement to upload more than 50K images at once. The current functionality of RadAsyncUpload supports uploading around 3000 pictures at once. I tried to upload 8000 pictures in your online demo page, but the page got stuck for several minutes and after the page started responding, it didn't even start uploading. All the characters on the page were distorted as well. Do you suggest anything that can help us meet the requirement?

Thanks,
Sriram.
