I have 2 tables which are related - Clients and ClientContact.

Clients -
ClientID int32
Company varchar
Active bit

ClientContact
ClientID int32
ClientContact varchar

When I use the dropdownlist control on the contact page and set the data source to only show active clients, if the current company is not active it disappears in in edit mode - should I be adding the current value in programmatically or changing the list on insert mode?

Hello,

I have two problems with my RadComboBox :

1. The RadComboBox doesn't resize automatically when we resize the browser window.
2. When we open the RadComboBox we show the dropdown, so far all is well, but when we "scroll" on the page, the dropdown detach from the input field (as you can show in the two picture attached below).

Here is the ASP.NET code :
                                            
Thanks for your help!

Hello,

Our project uses several UserControls that are used on different pages.
We load these UserControls dynamically in the page whenever they are needed.

This all works great, and fast, in our development environment.
But when we run it on the production server it takes ages.

We narrowed down the "slowdown" to the following lines of code:


This part of code takes .09 seconds on our development machine but takes almost 17 seconds on our production server.
What could make this run so slow?

When we trace the PageLoad in "mat_tab_detailinventar.ascx" we see that there is no delay there. It runs almost as fast as on our development server.

For your information.
Our development machines are all English wit XP. The production server is a German Win2003 SBS server.

Does anybody have an idea?

Thanks

Jelte

<telerik:ChartSeries DataXColumn="Date" DataYColumn="pct" Name="pct" Type="Line">

my data looks like
pct     reportDate
54      2012-09-01 00:00:00.000
65      2012-10-01 00:00:00.000  
57      2012-11-01 00:00:00.000   

when I put DataXColumn="reportDate"
I get an error saying column is not in numeric
when I put "Date" it shows chart but has 1900 dates.

do I just need to have the reportDate formatted in a specific format for it to know to use them as type dates?
do I have to have code behind that sets the dates in the databind?

Hi!

How do I implement the collapsing/burger menu that is used at www.Telerik.com (re-size the screen width to make it smaller and you get a burger menu) ?

Code snippet would be nice. Sample web page even nicer.

Thanks

Hi there,

I am able to bind a datatable to a radmenu.

I want to show images to the rad items and use a column in the datatable for this.
I cannot find the right property to the radmenu.

Anybody any idea??

Good day.   

I want to delete the Appointment inside the AdvancedEditForm of RadScheduler. So I added a Button in the form with the following attributes. 

<asp:Button ID="btnDeleteShift" runat="server" Text="Delete " Enabled="true" CommandName ="Delete" OnClientClick="return confirm('Are you sure you want to delete this appointment?')" OnClick="btnDeleteShift_Click" CausesValidation="false" />

 So when the User clicks OK in the javascript confirmation box, I will execute the code to delete: 

protected void RadScheduler1_AppointmentCommand(object sender, AppointmentCommandEventArgs e) { if (e.CommandName == "Delete") {  RadScheduler1.DeleteAppointment(e.Container.Appointment, false);  } }

The Problem with this is that when the appointment is deleted, the advancedEditForm will still be shown on screen with the values of the Appointment that have been deleted.  

1.  What  code should I use that I can execute that closes that advancedEditForm ? I should execute that one under the AppointmentDelete Event.  

2. Or, is there a code of the advanceeditform where can I use the existing Delete Confirmation Message Window of the appointment to be fired when I click My custom button, then afterwards closes the AdvancedEditForm?  

3. Or, is there a built in Delete function of the AdvanceEditForm to show a delete button and provides the delete functionality?

From what I see, the appointment can be deleted only when I click the X button on the appointment in the radscheduler.   

Hoping for your help and support. 
Thank you very much,  
Rommel
