Telerik 2009.1.402.20 Compatibility with .net

We are doing some work for a client who has a number of web applications which were initially built in .net 2.0 and which use Telerik 2009.1.402.20.

As part of some minor changes to the applications. We also upgraded to .net 4.0. This has caused a number of issues with the telerik controls and we are assuming that there are compatibility issues between this version and .net 4.0.

We tried to fix a number of issues by using the known _DestoryTree JS fix. However this doesn't seem to have worked for many of the issues.

Could someone please advise on the following:

1 - Is there anyway around the incompatibility?

2 - If not and an upgrade in Telerik is required will this in itself cause other issues with the migration from the old version to the new? Are there issues with backward compatibility.

Thanks for your help.

RadComboBox not rendered when within ASP panel with initial visisble=false

RadComboBox not rendered (Rendered as "") when within asp panel with initial visible= false.

The asp panel is set to visible= true when postback is triggered via client using ajaxManager.ajaxRequest('InitialPageLoad'

protected void Page_Load(object sender, EventArgs e)

        {

            // register ajax

            Telerik.Web.UI.RadAjaxManager ajaxMgr_CCF =   Telerik.Web.UI.RadAjaxManager.GetCurrent(Page);

            ajaxMgr_CCF.AjaxRequest += new RadAjaxControl.AjaxRequestDelegate(AjaxRequestsForCCF);

}

protected void AjaxRequestsForCCF(object sender, AjaxRequestEventArgs e)

       {

           if (e.Argument == "InitialPageLoad")

           {

              pnlWithComboBox.Visible = true;

           }

       }

RadCombobox is always set to visible = true.

The panel has other server side control but they render fine.

If I set radComboBox1.visible = true then it works fine. But should it automatically render and no need for setting specificly

<asp:Panel ID="pnlWithComboBox" runat="server" visible="false">

<telerik:RadComboBox ID="radcombobox1" runat="server" Width="123px" RenderMode="Lightweight" OnSelectedIndexChanged="btnSavePlaybackForward_Click" AutoPostBack="true" OnClientSelectedIndexChanged="comboBoxContext">

<Items>

<telerik:RadComboBoxItem Text="1" Value="1" runat="server" />

<telerik:RadComboBoxItem Text="2" Value="2" runat="server" />

<telerik:RadComboBoxItem Text="3" Value="3" runat="server" />

</Items>

</telerik:RadComboBox>

</asp:Panel>

function initializePage(sender, eventArgs) { var ajaxManager = $find('<%= RadAjaxManager.GetCurrent(this.Page).ClientID %>'); ajaxManager.ajaxRequest('InitialPageLoad'); } <telerik:AjaxSetting AjaxControlID="radAjaxManager1"> <UpdatedControls> <telerik:AjaxUpdatedControl ControlID="pnlWithComboBox" /> </UpdatedControls> </telerik:AjaxSetting>

RadEditor Loses Entered Value

I am trying to access text entered into a RadEditor but when I try to retrieve the value in a button click event there isn't any value there. It works fine in Chrome but not IE 11.

Here is the UI tag:

<telerik:RadEditor ID="reCommentsJDEItem" runat="server" ToolbarMode="ShowOnFocus" ToolsFile="~/BasicTools.xml" CssClass="td" Enabled="false"EditModes="Design" AutoResizeHeight="true" Height="80px"></telerik:RadEditor></td>

From the click event:

oPackSlipDetail.Comments = reCommentsJDEItem.Content;

No value appears even though something has been typed. Version I am using: 2016.1.113.35 Runtime: v2.0.50727

Thanks

Cascading combo boxes in edit form of RadGrid

I'm frustrated beyond belief. What I want to do seems simple enough. First, I'm using RadControls Q2 for ASP.NET AJAX. I have a grid of users with four columns (username, email address, state, city). I need to edit existing records in place and add new records. Some of the properties of the grid include EditMode="InPlace", AllowAutomaticUpdates="true" and AllowAutomaticInserts="true". The issue I am having is that I need to have the "cities" combo box populate based upon the selection of the "state" combo box. Seems simple enough. The combo boxes appear in edit and insert modes. The combo boxes also need to stay in sync for an "edit" of an existing row.

I see examples of loading on demand, but not in the edit/insert row of a RadGrid. Populating the first combo box is easy, but the second... aaarrgh. I can not find an example of how to 'find' the EditItemTemplate combo box in a javascript function attached to the "OnClientSelectedIndexChanging" event.

I found another telerik example that was using a streamer page. Is that old tech? I'm using Q2 ASP.NET AJAX.

Please help.

Edit template with colour picker

I have a radgrid bound by entity datasource and has the following column:

<telerik:GridTemplateColumn UniqueName="Color" HeaderText="Background Color" DataField="Colour" ItemStyle-Width="150px" ItemStyle-HorizontalAlign="Center"

SortExpression="myColor" AllowFiltering="false" HeaderStyle-Width="32px">

<ItemTemplate>

<div style='width: 16px; height: 16px; background-color: #<%# Eval("Colour") %>'></div>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadColorPicker runat="server" ShowIcon="true" ID="RadColorPicker1" SelectedColor='<%# System.Drawing.ColorTranslator.FromHtml("#" + Eval("Colour")) %>' />

</EditItemTemplate>

</telerik:GridTemplateColumn>

The datasource looks like this

<asp:EntityDataSource ID="eds1" runat="server" OrderBy="[it].Name" ConnectionString="name=DBSchoolsEntities" DefaultContainerName="DBSchoolsEntities" EnableDelete="True" EnableFlattening="False" EnableInsert="True" EnableUpdate="True" EntitySetName="Classifications" EntityTypeFilter="Classification">

</asp:EntityDataSource>

I have other columns on the grid that dont have EditItemTemplates and these fields update in the db just fine, but the colour picker column doesnt update in the database and I dont know why?

Closing Popup event

Hi all,

I have a grid and I use Popup for editing row. I use client side event OnPopUpShowing to set popup position and size. The problem is that my data contains text with symbols '<>' which are not allowed for web request and I need to replace them before request is sent to server. I can do it simple by javascript when any button is clicked, but I am not able to detect closing button (from top right corner).

Is there any client-side event when popup is closing?

Or is it possible to remove/hide closing button when dialog is showing?

Thank you for any idea,

Petr
