hi, I am just started working on Telerik Grid, but getting error as copied below. Please suggest me what needs to be done to fix it... Am i missing anything? Thanks, Pradip

Anyone done graphic click causes splitter move?

I'm trying to emulate a slide approach as done via js on the following web site:
http://www.gopconvention2008.com/

There would be a graphic inside a panel, and clicking the graphic would cause the panel to collapse. But, it would never collapse to be smaller than the width of the graphic.

Anyone done anything like this already using splitters? Have any ideas?

Or should I just take the js approach?

Thx

Editor strips width style from div?

Hi there,

I seem to have a problem with the editor rewriting some HTML code.

Whenever I put this code into the editor content and then click the Design button it strips width:700px; from the first div style.

Is this by design and is there any way of stopping it? I've tried setting ConvertToXhtml="True" to false however this doesnt make any difference.

    
            <div style="border: black 1px solid;width:700px;">  
        
            <div style="line-height: 50px; text-align: center;"><strong>Header</strong> 
        
            <div style="text-align: left;">  
        
            <ul style="top-margin: 0px;">  
        
                <li style="line-height: 30px;">Bullet 1</li> 
        
                <li style="line-height: 30px;">Bullet 2</li> 
        
                <li style="line-height: 30px;">Bullet 3</li> 
        
                <li style="line-height: 30px;">Bullet 4</li> 
        
            </ul> 
        
            </div> 
        
            </div> 
        
            </div>

Kind Regards

Binding Data To UserControl for Editing

I am trying to use a custom usercontrol for editing items in a RadGrid. The user control only has a textbox, the cancel and update buttons on it. I am trying to bind the textbox with via a bind statment but have an error returned. The description of the usercontrol is:

<%

@ Control Language="VB" AutoEventWireup="false" CodeFile="frmPartnerAttributing.ascx.vb" Inherits="frmPartnerAttributing" %>

<

asp:TextBox ID="txtPartnerAttributing" runat="server"

Text

='<%# DataBinder.Eval( Container, "Parent.BindingContainer.DataItem.PartnerAttributing") %>'

Width

="239px"></asp:TextBox>

<

br />

<

asp:Button ID="cmdUpdate" runat="server" Text="Update" />

<

asp:Button ID="cmdCancel" runat="server" Text="Cancel" />

The error is that the BindingContainer is a GridTableView which does not have a DataItem member. Is there something wrong with tis method of binding data to the textbox in the usercontrol? The method comes straight from one of the examples.

Thanks,

Grid

Link Manager and WSS

Hi,

We are currently evaluating the possibility of using RADEditor to replace the default WSS rich text editor.
We are very enthousiast about the possibility of your product but we have one question about the link Manager.

As we are using WSS and we are not planning to switch to MOSS in a near futur, we were woundering if their was a way to have a version of the Link Manager in the toolbar that is not requiring the AssetPicker (that generates the javascript error on WSS).

Is it something that exist and needs to be activated?
Is it something we can develop on our side and add to the toolbar?

It is an important issue for us since our webmaster use that functionnality alot and they are not familiar with HTML.

[Solved] Weird ComboBox Web Service Error

Hi

I'm using a webservice to populate a RadComboBox.

Here is my js:

    
            function OnClientItemsRequested(sender, eventArgs) {  
        
                    var items = sender.get_items();  
        
                    if (items.get_count() == 2) {  
        
                        OpenEntityWindowFromItem(items.getItem(1), sender);  
        
                    }  
        
                } 
        
            function HandleRequestStart(sender, eventArgs) {  
        
                    var context = eventArgs.get_context();  
        
                    context["Filter"] = sender.get_text();  
        
                }  
        
                function OnClientItemsRequestFailedHandler(sender, eventArgs) {  
        
                    alert(eventArgs.get_errorMessage());  
        
                    // set cancel to hide the default message      
        
                    eventArgs.set_cancel(true);  
        
                }  
        
                function OnClientSelectedIndexChanged(sender, eventArgs) {  
        
                    OpenEntityWindowFromItem(eventArgs.get_item(), sender);  
        
                }

Here is my markup (The web service path is set in codebehind):

    
            <telerik:RadComboBox ID="uxRadComboBox" runat="server" EmptyMessage="Search..." 
        
                 Skin="Web20" EnableEmbeddedSkins="false" 
        
                 OnClientItemsRequesting="HandleRequestStart" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" 
        
                 OnClientItemsRequested="OnClientItemsRequested" 
        
                 EnableLoadOnDemand="true" OnClientItemsRequestFailed="OnClientItemsRequestFailedHandler">  
        
                    <WebServiceSettings Method="GetSearch" /> 
        
                </telerik:RadComboBox>

Here is my webservice method:

    
             [WebMethod]  
        
                    public SearchComboBoxItemData[] GetSearch(object context)  
        
                    {  
        
                      .....  
        
                    }

Here is the SearchComboBoxItemData class:

    
            public class SearchComboBoxItemData  
        
                {  
        
                    public string Text { get; set; }  
        
                    public string Value { get; set; }  
        
                }

This all works fine on my local set, but on our production server when I click in the combobox, a windows explorer message box pops up saying: "There was an error processing the request." There isn't any error published to the event viewer. Is there anything I can do in my code to get more details about the error that is occurring, so I can fix it?

Thank You

Trial Messaging Popping Up

I have been a Telerik subscriber for a while now and have recently upgraded my VS.NET application from 2005 to 2008 and the frameworks from 2.0 to 3.5 and therefore loaded the latest version of the RadControls for the ASP.NET into this. I have also loaded the Hotfix as per the Knowledge base instructions to change from trial to my licensed copy. I have done this twice now. Everytime i think i have it fixed, all of a sudden the trial message reappears in my application. I want to load my app into production tonight and this is leaving me unsure to do so.

How can I be absolutely sure this is taken care of correctly (e.g. a registry entry, etc...), anyone have some advice.

Thank you

intellisense

Hi All,

does anyone know of how to unclude intellisense into the editor....

basically what I would like to do is identify when a user types in a word say sum( the editor will then produce a list of dynamic variables.

as you have probably guessed I am trying to provide a code writing editor for users to generate their own formulae based on custom specific criteria

Many Thanks

Mark
