auto filling other column works for edits but not adds

Hi Everyone,

In my grid there's 3 columns, "Client Id", "Client first name", "Client last name". The client first and last name columns are read only. When the user enters the Client Id the CellValueChange event is fired, which gets the first and last name for the Client Id from the database, then puts the first and last name values in their respective columns.

Here's the code:

Private Sub gridClients_CellValueChanged(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellEventArgs)

Dim column As GridViewDataColumn = TryCast(e.Column, GridViewDataColumn)

If column IsNot Nothing AndAlso column.FieldName = "ClientId" Then

e.Row.Cells(

"vcFirstName").Value = GetClientFirstName(e.Value)

e.Row.Cells(

"vcLastName").Value = GetClientLastName(e.Value)

End If

End Sub

This works great when editing existing records, but not at all for adding new records. During add new, the event does fire, and does get the correct first/last name values, and the code to put the first/last name value does fire and seems to work, but when looking at the cell value, nothing actually gets there.

If the new row is committed (by <enter> or clicking out of the row), then going back and setting the client id, the code works. But of course, that doesn't fulfill the requirements. The code needs to work by merely <tabbing> out of the Client Id column on a new row.

Thanks in advance for any and all suggestions and advice.

Appointment is shown even though not configured

Hi,
Today I was facing an issue on creating New Appointment.
Steps to Reproduce:
1. Double click on Monday (say, 7th Feb 2011) and assign the following settings
1.1. Recurrence type: Weekly
1.2. Days of the week: Tuesday and Wednesday only.
1.3. Range of recurrence: Start by: 7th Feb 2011 and End by: 18th Feb 2011.

when assigning the above settings, the Appointment occurrence on 7th Feb 2011 is shown in the view. Whereas it shouldn't be shown as Monday is not configured on the RecurrenceRule. Subsequent week is shown correctly.

I'm using the following version in my machine: Winforms Q1 2010 SP2.

Please let me know how this issue could be solved.

Thanks,
Arun.Dharuman

RadMenu autosize problem

I have a radmenu inside a user control. I had set the autosize=true and autosizemode=GrowAndShrink for the user control. For the RadMenu I had set autosize=true and Orientation=Horizontal. I am adding menu items dynamically. But the usercontrol that holds the RadMenu is not growing automatically and RadMenu grows into a second row. How can I make the usercontrol grow automatically as RadMenu add new Items horizontally. Please advice. Please see the attachment.

RadScheduler Resource Binding

Hello,
I am trying to follow along with webinars to learn the RadScheduler. I successfully was able to create an application that had no resources, create schedules etc...I can save appointments and the Appointments table in the Telerik provided example database populates fine and all..when I have one resource only.

The problem comes when I try to save to a RadScheduler with more than 1 resource.
AppointmentsResources table in database does not seem to populate. Also, newly created schedule item you just tried to save disappears. No appointments load up on initial load either.
I tried to emulate it working by creating a manual entry in AppointmentsResources table, to no avail, so I deleted entry.
However, Appointments table still populates correctly.

Code is simple
Using Telerik provided database. Thank you very much!

Imports Telerik.WinControls.UI

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

'TODO: This line of code loads data into the 'SchedulerDataDataSet.Resources' table. You can move, or remove it, as needed.

Me.ResourcesTableAdapter.Fill(Me.SchedulerDataDataSet.Resources)

'TODO: This line of code loads data into the 'SchedulerDataDataSet.Appointments' table. You can move, or remove it, as needed.

Me.AppointmentsTableAdapter.Fill(Me.SchedulerDataDataSet.Appointments)

RadScheduler1.ActiveView.ResourcesPerView = 5

RadScheduler1.GroupType = GroupType.Resource

End Sub

Private Sub SaveToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles SaveToolStripMenuItem.Click

Dim appointmenttableadapter As New SchedulerDataDataSetTableAdapters.AppointmentsTableAdapter()

Dim resourcetableadapter As New SchedulerDataDataSetTableAdapters.AppointmentsResourcesTableAdapter()

Try

appointmenttableadapter.Update(SchedulerDataDataSet.Appointments)

resourcetableadapter.Update(SchedulerDataDataSet.AppointmentsResources)

SchedulerDataDataSet.AcceptChanges()

Catch ex As Exception

Throw ex

Finally

End Try

End Sub

End Class

Missing Events on CommandBarDropDownList

In building a user control where a ToolWindow hosts a RadCommandBar with a CommandBarDropDownList.
When browsing the associated events, I'm missing the SelectedValueChanged, SelectedIndexChanged. Even when I tried to add event handlers programmatically, they do not show up.

I’m using version v.2010.3.10.1109, with Visual Studio 2008 sp1 + .NET Framework 3.5 sp1, in a WinForms application.

I've tested this in another clean project, and the events do show up, however, the environment is Visual Studio 2010 + .NET Framework 3.5 sp1, and the suite's version is v.2010.3.10.1215.

Is the problem located on such diference of versions?

UPDATE:

YES, the issue is fixed on v.2010.3.10.1215 which contains the missing events. I just upgraded the tools and the project is now showing the events.

How to get value from 3rd table in gridview

I am using Gridview (Hierarchy) to display data from the database Northwind with a small modification:
- table Orders has following columns: OrderID, OrderDate
- table Details has: DetailsID, OrderID, ProductID, Quantity, UnitPrice, Total (Total is one column in Gridview using expression)
- table Products has: ProductID, ProductName, TaxID
- table Tax has: TaxID, Tax
The Orders table is parent table and the Details table is child table. With the ProductID and GridviewComboboxColumn I can display ProductName from the Products table, but I don't know how to get the Tax value from table Tax using the same method to complete the goal: Total=Quantity*UnitPrice*(1+Tax).
Do you have any idea to do that?
Any help would be appreciated.

[Solved] Exporting a theme as a package after color blending

Hello,

I am using the windows 7 theme. I want my application color to be red so I use color blending. I am not totally satisfied with the result, so I would like to edit the generated red theme in the VSB as it is mentioned in this blog post :

http://blogs.telerik.com/blogs/posts/08-10-31/chameleon_skinning_coming_up_to_winforms_in_q3_2008.aspx
"And finally if the resulting skin still needs some touches, you can export the modified theme data to xml files, and tweak them using the Visual Style Builder app, as much as you wish. "

To export the theme I used the code attached in this thread, that uses XmlStyleBuilderRegistration objects.
http://www.telerik.com/community/forums/winforms/themes-and-visual-style-builder/theme-and-addcolorblend-not-working.aspx

This code generated 56 Xml files. I start the VSB and hit "Open directory" to load all xml file but VSB says that these files are old and no more supported.

How can I export a color blended theme to edit it in the new VSB?

Thank You
Regards
Thibaut
