Same Appointment, Different Days?

Hi,

I have been evaluating the scheduler component on the website, I am yet to download it and test it. I will be using it to schedule 25 mechanics, there appointments will last between half a day and 2 weeks. I imagine the view would be grouped by resource vertically (like in the attachment).

The one stumbling block I can see is one appointment cannot be scheduled on non consecutive days. Meaning I want the appointment "Training Session 1" to be on the 8th and the 10th, as seen in the attached file. I cannot do it with one appointment, the job will need multiple appointments, correct?

If it does need to multiple appointments for the one job, is it possible to setup a function that would give the users the ability to copy an appointment though a drag and drop?

Cheers,
Grant

Telerik.Web.UI assembly error

Hello,

So this is the first time I download and test telerik ASP.NET AJAX. Before I even start to use or run my website that I created using C# I get the attached error before the run time.

I have attached a zip file created by the problem step recorder in windows7, so you can see the images at the buttom of the generated file.

http://zipmyfiles.net/uploads/100308102558-44545.zip

you can notice I can see the calender during the run time but not before that.

I'm using Visual Studio 2008 Academic.

Any idea why I'm getting this error ?

Thanks,
Musab

Binding a control to a System.Web.UI.WebControl.Menu

Hey everyone,

I am a little new to your product, however, I am trying to use one of your controls in place of the above mentioned class. The problem I am having is there is some 3rd party code that looks like this...

    
            public void PopulateStoreMenu(Menu ctrlMenu);

As you can tell it adds all the information to the Menu object. Now assuming I don't have access to the source code is there a way to...

A.) Use a control that extends the Menu class

or

B.) Bind data to the control some other way

I was thinking maybe I could use Linq on the Menu and bind it to that, however, I am a Linq newbie so advice would need to be given.

Thanks in advance guys!

Jackie

P.S. I posted this here because I wasn't sure which control to post it under :-)

[Solved] GridDropDownColumn - specific Filter Field

Hi,

I'm using your griddropdowncolumn very nicelly, but realized there's a problem with the filtered field it uses by default.
Facts:

have 2 tables related in grid
one table named Table with these columns IDTable, TableDesc, IDForeign
my foreign table is called Foreign and has IDForeign and ForeignDesc columns
columns in Grid are: TableDesc (GridBoundColumn) and ForeignDesc(GridDropDownColumn)
grid alows filtering
Filter works fine in column TableDesc but NOT in ForeignDesc

If you insert data in both tables and try to filter by any content in the ForeignDesc column it doesn't return anything, it only works if you use the IDForeign content in the filter. It should be possible to use the ForeignDesc content for filtering the data, no?
What am I doing wrong? Here's what I have.

    
            <telerik:RadGrid ID="rdTableForeign" runat="server" DataSourceID="sdsTable" AllowPaging="True"

RadListView & RadDataPager

Hello,

I have a really strange problem.

I'm working with the Q1 2010.

I want to use the RadListView as a list of news. With a pagesize of 1 and the newest post first. So i put in my asp:EntityDataSource :OrderBy="it.Date DESC"

                    <telerik:RadListView ID="RadListView1" runat="server" DataKeyNames="IdPost"          
                    DataSourceID="EntityDataSourceNews" AllowPaging="True" ItemPlaceholderID="itemPlaceholder"  InsertItemPosition="None"         
                    OnItemCommand="RadListView1_ItemCommand" PageSize="1">

                    EnableFlattening="False" EnableInsert="True" EnableUpdate="True"          
                    EntitySetName="Posts" OnInserting="EntityDataSourceNews_Inserting"         
                    OrderBy="it.Date DESC">         
                </asp:EntityDataSource>         
                     

The thing is that the first item which appear, is the oldest one ! (So it's not working)

But, if i go to the page 2, then come back to the page 1 it's the newest one !

I mist something ?

Thank you

Strange RadComboBox Appearance

I am using a RadGrid with an embedded RadComboBox, using the Default skin. I'm tight for space so I overrode the styles for the RadGrid to reclaim some space as below:

                    div.Ironwood.RadGrid_Default .rgFooter td         
            {         
                border-bottom:0px;         
                padding-left:4px!important;         
                padding-right:4px!important;         
            }         
            div.ManagersInTheNews.RadGrid_Default .rgRow,         
            div.ManagersInTheNews.RadGrid_Default .rgAltRow,         
            div.ManagersInTheNews.RadGrid_Default .rgRow td,         
            div.ManagersInTheNews.RadGrid_Default .rgAltRow td         
            {         
                font-family:Arial;         
                font-size:11px;         
                border-bottom:0px!important;         
                vertical-align:middle!important;         
                padding-left:4px!important;         
                padding-right:4px!important;         
            }         
                     

I am also adding the RadComboBox to the bottom row (added programmatically). Without the overrides for the paddings, it appears normal, however with the overrides, it appears as in the attached image. Is there something I can do to get the background image to align better?

Thanks, Steve

[Solved] The Controls collection cannot be modified because the control contains code blocks Error..

Hi

I had the following Server Error after including a RadAjaxManager to a Webpage:

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

In many forums they said to be sure to remove all code blocks (<% %>) in the Head-Section of the Page.
Or delete the runat="server" from the Head-Section.

Noting helped in my case. But the ting with the code blocks helped me find it out.
It had nothing to do with the Head-Section of the Page or the Master-Page.

I simply had to remove the code blocks IN my page.

That's the page-code that produces the Error:

    
            <%@ Page Language="vb" AutoEventWireup="false" CodeBehind="Default.aspx.vb" Inherits="CollectionModifyProblem._Default" %>

            <telerik:RadListBox ID="lstbCarTypes" runat="server"></telerik:RadListBox> 
        
            </div> 
        
            <telerik:RadAjaxManager runat="server">  
        
            <AjaxSettings> 
        
            <telerik:AjaxSetting AjaxControlID="lstbBrands">  
        
            <UpdatedControls> 
        
            <telerik:AjaxUpdatedControl ControlID="lstbCarTypes" /> 
        
            </UpdatedControls> 
        
            </telerik:AjaxSetting> 
        
            </AjaxSettings> 
        
            </telerik:RadAjaxManager> 
        
            </form> 
        
            </body> 
        
            </html>

After a while I replaced the two code-blocks with labels:

    
            <%="Select a Brand (norally I use a var here):"%> 
        
            to  
        
            <asp:Label runat="server" ID="lblTitle_Brands">Select a Brand (noraly I fill this by code):</asp:Label>

and

    
            <%="Select a Type (norally I use a var here):"%> 
        
            to  
        
            <asp:Label runat="server" ID="lblTitle_Type">Select a Type (noraly I fill this by code):</asp:Label>

That's all you have to do!

Maybe this will help also others!

Freundliche Grüsse

Table Layout in FormTemplate used in RadGrid

Hi

I am trying to move away from using table layout in my web applications. I am busy implementing the "Grid/Form Template Edit Form" Grid example and noticed that the FormTemplate is using a table layout. Is this the recommended way or is this for illustration purpose only? What would be the correct way to implement the FormTemplate?

Thank You
Fred
