OnClientLoad, ApplyClass - "Object does not support this property or method"

Hi, spent a bunch of time nogging over this one. Finally figured it out. I traced it all the way back to the Telerik.Web.UI.Editor.RadEditor.js. I'm using Q1 2009 RadControls for ASP.NET Ajax.

I was getting a "Object does not support this property or method" error when using the following script:

    
                <script type="text/javascript">  
        
                    function OnClientLoad(editor, args) {  
        
                        editor.fire("SelectAll");  
        
                        editor.fire("ApplyClass", { value: ".default" });  
        
                    }  
        
                </script>

Figured out that it need an object with a get_value() method:

    
                <script type="text/javascript">  
        
                    function OnClientLoad(editor, args) {  
        
                        editor.fire("SelectAll");  
        
                        objCssClass = new Object(); objCssClass.get_value = function() { return ".default"; }  
        
                        editor.fire("ApplyClass", objCssClass);  
        
                    }  
        
                </script>

Hope this saves someone a few hours :)

Row Select/Check Issue

Happy New Year Telerik!

I have a grid with a RowSelected client event that fills in other controls on the page. The grid has a "clientselectcolumn". On loading I populate the grid with serverside code. I also fire a "item.selected = true" in the PreRender, which successfuly checks the first row and "clientselectcolumn" column, but it doesnt fire the RowSelected that fills in the controls on the page.

How can I go about checking and selecting the first row and filling in the other controls on the page load? I also want to implement this on the ItemCreated, so it checks the new row and fills in the default data I set on the postback for the other controls. This data is set up in the grid with the Client/DataKeyNames in a single query and on the RowSelected it fills in the other page controls.

Thanks!
SDI

Event

Dear Telerik-Support,

I use a RadButton and the Event OnClientClicking with the parameter sender, args.

I need the dom Event in this method. I try it with the global event reference and it only works for IE because Firefox etc. are not implement this global event reference. So I try it with an anoynomous function

Button property

OnClientClicking = function(sender, args) { FnButton_ClientClicking(sender, args, event) };

JavaScript

function FnButton_ClientClicking(sender, args, e)

{

}

but in the function e will be undefined on firefox.

Whats wrong here? How can I parse the dom event to the function. If I try the same with an ImageButton and the OnClientClick Event the Browesers parse by using (this, event) all what I need!

Thanks for help,

Kind regards,
Christian

How to display a HeaderTooltip when AllowColumnsReorder is set to true, and AllowSorting is set to false for the specific column?

I created this little prototype to illustrate the problem I'm having.

Basically, the 'UnitsInStock' column is not displaying the tooltip.

Notice that if you set AllowSorting=True for the column or set AllowColumnsReorder=False in ClientSettings, then the tooltip will work.

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"

CodeBehind="Default.aspx.cs" Inherits="HowToDisplayHdrTooltipsInTelerikRadgrid._Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

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

</asp:Content>

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

<asp:ScriptManager runat="server" />

<telerik:RadGrid ID="grid" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource1" AllowSorting="true"

GridLines="None">

<ClientSettings AllowColumnsReorder="True">

</ClientSettings>

<MasterTableView DataKeyNames="ProductID" DataSourceID="SqlDataSource1">

<CommandItemSettings ExportToPdfText="Export to Pdf"></CommandItemSettings>

<Columns>

<telerik:GridBoundColumn DataField="ProductID" DataType="System.Int32" HeaderText="ProductID"

ReadOnly="True" AllowSorting="true" SortExpression="ProductID" UniqueName="ProductID" HeaderTooltip="product id tooltip">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="ProductName" HeaderText="ProductName" AllowSorting="true" SortExpression="ProductName"

UniqueName="ProductName" HeaderTooltip="product name tooltip">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="CategoryName" HeaderText="CategoryName" SortExpression="CategoryName"

UniqueName="CategoryName" HeaderTooltip="category name tooltip">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UnitPrice" DataType="System.Decimal" HeaderText="UnitPrice"

SortExpression="UnitPrice" UniqueName="UnitPrice" HeaderTooltip="unit price tooltip">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="UnitsInStock" DataType="System.Int16" HeaderText="UnitsInStock" AllowSorting="false"

UniqueName="UnitsInStock" HeaderTooltip="units in stock tooltip">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthwindConnectionString %>"

SelectCommand="SELECT [ProductID], [ProductName], [CategoryName], [UnitPrice], [UnitsInStock] FROM [Alphabetical list of products]">

</asp:SqlDataSource>

</asp:Content>

PS - I'm using version 2010.2.929.40

2. Add an RadDatePicker Control

</telerik:RadDatePicker>

3. compile and Run.
4. Select a date
5. place the cursor in the text box RadDatePicker control, or rather, place the focus on the control RadDatePicker
6. Immediately after the button click of RadRibbonBar (skip the error here)

ImageManager not working in v5.8.15 (and v5.8.16)

Hi, we've been looking at upgrading our version of the RadEditor for Sharepoint to version 5.8.15 (although now version 5.8.16 has been released we've moved to evaluating that version on our development platform.

We are having problems using the 'ImageManager' button. When it is used to select an image the HTML for the <img> is not returned to the page. If we use the 'MOSSImageManager' the HTML is returned to the page.

In our opinion the functionality of the 'ImageManager' is more suitable as it has a better interface for the content authors to use (particularly the upload function but also the image editor features) so we would like to continue using that version of the button.

In the ToolsFile.xml the tool we want to use is specified as
<tool name="ImageManager" shortcut="CTRL+G" />

Is there any issue with the ImageManager button with the latest version of the RadEditor for Sharepoint?

Thanks
Peter
