Dynamic Resources

[L]

hi

My company has a high turnover rate of employees and given the code sample telerik provided it is not dynamic for my situation. How do i make it dynamic without changing anything at the aspx page whenever there is a change at the employee table? thanks

 <ResourceTypes>
         <telerik:ResourceType KeyField="ID" Name="User" TextField="UserName" ForeignKeyField="UserID"
                        DataSourceID="UsersDataSource" />
  </ResourceTypes>
                <ResourceStyles>
                    <telerik:ResourceStyleMapping Type="User" Text="Alex" ApplyCssClass="rsCategoryBlue" />
                    <telerik:ResourceStyleMapping Type="User" Text="Bob" ApplyCssClass="rsCategoryOrange" />
                    <telerik:ResourceStyleMapping Type="User" Text="Charlie" ApplyCssClass="rsCategoryGreen" />
                </ResourceStyles>

Hi,

If you want to change the style of the appointments for which different users are selected, you could use the following code:

protected void Page_Load(object sender, EventArgs e)
{
    foreach (Resource res in RadScheduler1.Resources.GetResourcesByType("User"))
    {
        ResourceStyleMapping resMapping = new ResourceStyleMapping();
        resMapping.Key = res.Key.ToString();
        resMapping.BackColor = System.Drawing.Color.FromArgb(100, 100, 200);

        RadScheduler1.ResourceStyles.Add(resMapping);
    }
}

You could create a random integer generator which will create integers in a range from 0 to 255, so for different user you will have different color for the appointment.

<telerik:RadScheduler ID="RadScheduler1" runat="server" AppointmentStyleMode="Default" >
</telerik:RadScheduler>

The AppointmentStyleMode property set to Default will preserve the rounded corners of the appointments after applying the style.

All the best,

I'm trying to implement this example but its not working for me on the initial page load, it works if the scheduler has an item edited/inserted/deleted and performs another post back.  I also tried to do this on the page.init and that didnt work either.  Ideas?

Imports Telerik.Web.UI
Imports System.Drawing
Imports System.Random

Public Class VacationCalendar
    Inherits System.Web.UI.Page

    Private m_Rnd As New Random

    Public Function RandomRGBColor() As Color
        Return Color.FromArgb(255, _
            m_Rnd.Next(0, 255), _
            m_Rnd.Next(0, 255), _
            m_Rnd.Next(0, 255))
    End Function

    Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
        ResourceStyles()
    End Sub

    Protected Sub ResourceStyles()
        For Each res As Resource In RadScheduler1.Resources.GetResourcesByType("Area")
            Dim resMapping As New ResourceStyleMapping()
            resMapping.Key = res.Key.ToString()
            resMapping.BackColor = RandomRGBColor()

            RadScheduler1.ResourceStyles.Add(resMapping)
        Next
    End Sub
End Class

Hi Ryan,

 
Such behavior may be observed if the resources are not loaded initially and the event does not get into your ForEach loop. 

Hope this will be helpful.

I added a textbox to the loop and set the text to test at the end of the function/loop and the text is being set so I know its getting thru the function/loop the problem appears to be the scheduler isn't refreshing.  Like I said once I add a new event the colors then appear.  How do I force a refresh/redraw of the scheduler?  I tried a .Rebind() and that didn't do anything.

Hello,

Please find attached a sample project based on your code. A possible reason for this unusual behavior would be that your resource type name in the markup does not match the one used in the code behind.

//markup

<ResourceTypes>
            <telerik:ResourceType DataSourceID="SqlDataSource2" ForeignKeyField="UserID"
                KeyField="ID" Name="User" TextField="UserName" />
</ResourceTypes>

//code behind

Protected Sub ResourceStyles()
        For Each res As Resource In RadScheduler1.Resources.GetResourcesByType("User")
......
        Next
End Sub

Hope that this will be helpful.

I ended up just applying it to the RadScheduler1.AppointmentDataBound
