Urgent help needed for User control with RadScheduler

[Andy Green]

Hi

I hope someone can answer fairly quickly.

I have a Rad Scheuler control as a user conrtol I have set up 2 properteries ID and week Number, and create the control programatically based on the number of weeks, the web can display any number of grids from 1 to 12.

This all works well.

What I need to do is fill the grid with each weeks data, this means getting the Scheduler's ID and binding it to my recordset.

This is my error when I try:
Unable to cast object of type 'ASP.JobPlanScheduler' to type 'Telerik.Web.UI.RadScheduler'.

And this is my code to find the scheduler control,

Dim

 

rsJobPlan = CType(Page.Master.FindControl("ctl00$cphContent$JobPlanWeek" & WeekCycle), RadScheduler)

 

and this is the top section of my user contol vb file.

Hi Andy,

Can you isolate the problem in a simple working demo project and send it to us via a support ticket?

Hi

Whilst putting a simple version together, I found the problem, I was trying to convert my custom contol to a Rad scheduler, not the schedule control within my control, I was 1 level too high.

Anyway I've now got a correct handle on the contol, but it wont fill with data. I know I'm on the control because I can change the background colour to suit the ID, I've tried with / and with out databind(), am I doing anything obviously wrong.

 

Dim rsJobPlan As RadScheduler = CType(Page.Master.FindControl("ctl00$cphContent$cxJobPlan" & WeekCycle & "$rsJobPlan"), RadScheduler)

  

 

With rsJobPlan

 .DataKeyField =

"Session_ID"

 

 

 

.DataStartField = "StartTime"

 

 

 

.DataEndField = "EndTime"

 

 

 

.DataSubjectField = "Location"

 

 

 

.DataSource = ds

 

.DataBind()

.BackColor = Drawing.ColorTranslator.FromHtml(

"#" & WeekCycle * 2 & WeekCycle * 2 & WeekCycle)

 

 

End With

 

 

 

I do have data - I have single stepped the code and I have 10 rows in the datasource.

Hello Andy,

Which event do you use to bind RadScheduler? Have you tried this in Page_Load?

Hi

Yes I'm doing it in the page load of my user control, I pass in an ID as each user control instance has different data.

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


        LoadSessions(JobPlan_ID, Cycle)
        Me.lblCycle.Text = "Week " & Cycle

    End Sub


    Protected Sub LoadSessions(ByVal JobPlan_ID, ByVal WeekCycle)

        Dim jp As New JobPlan
        Dim ds As Data.DataTable = jp.GetSessionByJobPlanWeekCycle(JobPlan_ID, WeekCycle)

        Dim rsJobPlan As RadScheduler = CType(Page.Master.FindControl("ctl00$cphContent$cxJobPlan" & WeekCycle & "$rsJobPlan"), RadScheduler)

        With rsJobPlan
            .DataKeyField = "Session_ID"
            .DataStartField = "StartTime"
            .DataEndField = "EndTime"
            .DataSubjectField = "Location"
            .DataSource = ds
            .DataBind()*****************************
        End With

    End Sub

If I break where I've shown *********** and look t the datasource I have rows.

Hello Andy,

Try calling Rebind() instead of DataBind(). If this does not help, please open a support ticket and send us a simple working demo project.

I've changed the scheduler to a radgrid and it works OK, in that the correct data is displayed, so the problem must be the way I'm doing the data binding on the scheduler control.

I've found the problem, my data from the databse was last weeks, so whilst it still came back in the recordset, the scheduler decided not to show it.

Just have to figure out how to get the scheduler to display a date range and that should be it.

For now :-)

Hello Andy,

I am a bit confused as to what exactly the problem is. Is it that you have to navigate one week backwards to see the appointments. If yes, then you might need to set the SelectedDate property to the Start time of your first appointment from the record set.
