Hello,

I can't figure out how to get the RadSchedulerReminder to recognize that Appointments loaded from the database have already been dismissed.

I have a custom Appointment class that inherits from Appointment.
My database table has a Dismissed column.
I set the Dismissed property to the value of the column when I load my appointments from the database. *All* my appointments have Dismissed = True at this point and they all have a start time of close to now.
I set the RadScheduler.DataSource = BindingList(Of CustomAppointment)
I start the RadSchedulerReminder.
I get the reminder screen with every one of my appointments in it even though their Dismissed property is True.
If I dismiss the appointments manually with the Dismiss button, they remain dismissed until I restart the application at which point it ignores the initial value of the property again.

How do I get the RadSchedulerReminder to recognize the existing Dismissed state when it starts up?

Thanks.

Hierarchical Data Programmatically

Hello,

im testing Telerik at the moment and come to an issue. I've searched your whole site for my problem, but i cant find any answer.

I'm trying to bind a hierarchical DataGrid to SQL, but i dont want to use TableAdapters. Instead of it i want to relaize it with a DataReader or something like that.

So my DataGrid loads the data very well, but when i try to make a template/relation nothing happens. There are still just the rows from the Parent, but the child data is missing. I've tried different ways with datasets, to refresh the DataGrid and many more, but nothing works. When i bind it to TableAdapters, it is working well! So here is my code - hope you can help me out...

Private Sub FrmKundenliste_Load(sender As Object, e As EventArgs) Handles MyBase.Load

Dim objconn As New SqlConnection(My.Settings.SQL_V4)

Dim rs As New SqlCommand("", objconn)

Dim dr As DbDataReader

rs.CommandText = "Select * from dbo.ApplicationMain"

Try

objconn.Open()

dr = rs.ExecuteReader

If dr.Read() Then

RadGridView1.DataSource = dr

Dim objconn_detail As New SqlConnection(My.Settings.SQL_V4)

Dim rs_detail As New SqlCommand("", objconn_detail)

Dim dr_detail As DbDataReader

objconn_detail.Open()

rs_detail.CommandText = "Select * from dbo.ApplicationDetail"

dr_detail = rs_detail.ExecuteReader

If dr_detail.Read() Then

Dim template As New GridViewTemplate()

template.DataSource = dr_detail

RadGridView1.MasterTemplate.Templates.Add(template)

Dim relation As New GridViewRelation(RadGridView1.MasterTemplate)

relation.ChildTemplate = template

relation.RelationName = "ApplicationDetails"

relation.ParentColumnNames.Add("Id")

relation.ChildColumnNames.Add("ApplicationId")

RadGridView1.Relations.Add(relation)

End If

Catch ex As Exception

End Try

End Sub

Can I support scrolling in vertical StackLayoutElement?

I implemented a scrum-like board as described in this thread building on the "tickettest" example:
http://www.telerik.com/community/forums/winforms/gridview/winform-controls-to-build-a-scrum-like-status-board.aspx

At times there can be more cards in a column than will show. We'd like a vertical scrollbar to appear in each column when there are more cards in the StackLayoutElement column than can show.

How can I do this?
If you could indicate how to modify the tickettest example to demonstrate this, I'm sure I could take it from there.

(e.g. When you run the tickettest example and then grab the lower window edge and make the window shorter, I want a vertical scroll bar to appear in each column when the window edge goes above the lowest card.)

[Solved] GridViewBrowseColumn SelectedFile Event

I have a RadGrid with 4 columns;
- Checkbox,
- Image,
- TextBox,
- BrowseColumn
What I want to do is update the first 3 columns based on the filename selected from the Dialog in column 4. I have tried ValueChanging events, validation etc. but they don't do what I need. Specifically;

1. User clicks the 'Add New Row' button
2. I want to set the focus/editor on col 4
3. User clicks the '...' dialog button in col 4 and opens the FileDialog
4. User selects a filename, FileDialog closes
5. I want to trap the event now so I can insert values into cols 1-3.

All the other events I tried do not fire until the cell loses focus or enter is pressed etc. I want to fire as soon as the Dialog.FileName is returned to the cell. Anyone know how to do this? Thanks.
