Hello,

I would like to allow the users to select the number of minutes per row of the Scheduler themselves.

I'm trying to reproduce a small part of the Scheduler customization demo page available there:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/customization/defaultcs.aspx

In my very simple example, I only have a drop down list to select the number of minutes and a Scheduler component with no datasource.


Page:
        <telerik:RadScriptManager runat="server" ID="RadScriptManager1" /> 
          
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
            <AjaxSettings> 
                <telerik:AjaxSetting AjaxControlID="Panel1">  
                    <UpdatedControls> 
                        <telerik:AjaxUpdatedControl ControlID="Panel1" LoadingPanelID="RadAjaxLoadingPanel1" /> 
                    </UpdatedControls> 
                </telerik:AjaxSetting> 
            </AjaxSettings> 
        </telerik:RadAjaxManager> 
        <telerik:RadAjaxLoadingPanel runat="server" ID="RadAjaxLoadingPanel1" /> 
          
        <asp:Panel runat="Server" ID="Panel1">  
                Minutes per row:   
                <asp:DropDownList runat="server" ID="MinutesPerRow" AutoPostBack="true">  
                    <asp:ListItem Value="60" Text="60"></asp:ListItem> 
                    <asp:ListItem Value="30" Text="30" Selected="true"></asp:ListItem> 
                    <asp:ListItem Value="15" Text="15"></asp:ListItem> 
                    <asp:ListItem Value="10" Text="10"></asp:ListItem> 
                </asp:DropDownList> 
                         
            <telerik:RadScheduler runat="server" ID="RadScheduler1"   
                 ShowFullTime="true" OverflowBehavior="Expand" 
                 DataKeyField="ID" DataStartField="Start" DataEndField="End" DataSubjectField="Subject" >                 
            </telerik:RadScheduler> 

Code behind:
    protected override void OnPreRender(EventArgs e)  
    {  
        base.OnPreRender(e);  
 
        RadScheduler1.MinutesPerRow = int.Parse(MinutesPerRow.SelectedValue);  
    } 

This example completely failed.
When I select a value in the drop down list the Panel is refreshing but the Scheduler is still displaying the previous selected value.
I have to do a second post back to obtain the correct layout.

Did I forget something?

Thank you for you help.

Hello Mike,

You should use Rebind() to refresh RadScheduler:

protected override void OnPreRender(EventArgs e)
    {
        base.OnPreRender(e);
  
        RadScheduler1.MinutesPerRow = int.Parse(MinutesPerRow.SelectedValue);
        RadScheduler1.Rebind();
    }

Thank you it works great now but it means your live example is incomplete.

However I tried to go further and tested this functionality on client side (with a RadScheduler populated with a Web Service).

I added an input button which calls the following javascript fucnction on the OnClick event:

 

 

 function Btn_onClick() {  
     var scheduler = $find("<%= RadScheduler1.ClientID %>");  
     scheduler.set_minutesPerRow(15);  
     scheduler.set_timeLabelRowSpan(4)  
     scheduler.set_selectedDate(scheduler.get_selectedDate());  
 }       

I encounter a very strange problem as you can see on the image I attached.

When MinutesPerRow = 15 is setted, the day ends not at 23:59 but at 01:00 of the next day.

When MinutesPerRow = 20 is setted, the days ends not at 23:59 but at 21:59.

 

It seems there’s something very strange and I can’t achieve what I would like.

Is there a solution for this problem?

I forgot to mention that each time you click on the button it adds new lines in the scheduler.

Hi Mike,

When using Web Service binding, RadScheduler renders the control structure on the server for both increased performance and reduced JavaScript size. This means that changing view parameters such as MinutesPerRow and TimeLabelRowSpan is not supported on the client and requires full postbacks. We can offer help with this approach if needed.

The supported operations are changing the selected date, adding/editing/removing appointments and switching views. Some other operations can be achieved with custom code, but changing the MinutesPerRow property is not amongst them.

I hope this helps.

Hi,

 

Ok I understand but I’m wondering why these two functions (set_minutesPerRow & set_timeLabelRowSpan) are available on client side if they are not supported?

In which case/situation are they useful?

 

I’m trying the server-side approach to achieve this functionality with my RadScheduler populated with a web service.

I added an asp:Button with the following server-side code on the onClick event:

 

 

    protected void OnClick(object sender, EventArgs e)  
    {  
        RadScheduler.MinutesPerRow = 10;  
        RadScheduler.TimeLabelRowSpan = 6;  
        RadScheduler.Rebind();  
    } 

 

I don’t specified a default selected date (so when the page loads the scheduler displays the current day) and the default view type is DayView.

 

Everything is working well except when I change on client-side the date and then click on the button. The page loads at the current day again (which is absolutely normal).

But I would like to keep the last date selected by the customer, so find a way to get this date and set it to the scheduler.

 

Is there a simple way to do that?

 

Thank you.

Hello Mike,

I have forwarded your question about the set_minutesPerRow and set_timeLabelRowSpan methods to our developers who will be able to answer it next week.

As for the other question, handle OnClientNavigationComplete to store the currently selected date in a hidden field. Then parse the value in code behind and set RadScheduler's SelectedDate property:

<script type="text/javascript">   
    function OnClientNavigationComplete(sender, eventArgs) {      
        var currentlySelectedDate = document.getElementById("currentlySelectedDate");
        currentlySelectedDate.value = sender.get_selectedDate().format("yyyy/MM/dd");
    }
    </script>
      
    <asp:Button ID="Button1" runat="server" Text="button" onclick="Button1_Click" />   
    <asp:HiddenField ID="currentlySelectedDate" runat="server" />
    <telerik:RadScheduler
        runat="server" 
        ID="RadScheduler1" * * * />

protected void Button1_Click(object sender, EventArgs e)
       {
           RadScheduler1.MinutesPerRow = 10;
           RadScheduler1.TimeLabelRowSpan = 6;
           if(currentlySelectedDate.Value != null)
               RadScheduler1.SelectedDate = DateTime.Parse(currentlySelectedDate.Value);
           RadScheduler1.Rebind(); 
       }


Best wishes,

Hi Peter,

I have similar issue but I am using RadScheduler in MVC. It would be kind if you can help identify how to set MinutesPerRow property on server side (or in client side) in MVC.

Thanks in advance.

Hello Camilo,

This is an MVC related question and I cannot advise you on an expert level with this. I suggest you post your question in our MVC forums - http://www.telerik.com/community/forums/aspnet-mvc.aspx.

Hello Santosh,

Unfortunately, setting minutes per row client side is not supported. Please, excuse us for this limitation of the control.

Hi Santosh,

Can you add the following ajax setting and check if it helps?

<telerik:AjaxSetting AjaxControlID="MinutesPerRow">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="MyScheduler1" LoadingPanelID="RadAjaxLoadingPanel1" />
                </UpdatedControls>
            </telerik:AjaxSetting>


All the best,

Hi,

The PreRender event is propbably too late. Can you try the same code in the SelectedIndexChanged handler of the DropDownList control?

Hi Santosh,

The MVC environment does not support server-side event handling, so this requirement cannot be implemented.
