Combining Themes

Hi,
I have a RadRibbonBar that I want to render as Office2007Black and a RadDock that I want to render as Office2010Black on my Windows Form at the same time, hopefully without using a custom application wide theme.

Note : on the development environment I can set the RadRibbonBar to Office2007Black and the RadDock to Office2010Black, yet it runs only with the Office2010Black theme.

I would like to use both themes at runtime :
WinForm :
RadRibbonBar = Office2007Black
RadDock = Office2010Black.

Looks great if I can get it to apply at runtime. Any ideas?

Hierarchy Tabbed View

Hi,

I found a bug during testing.
Currently I'm using RadControls for WinForms Q2 2011
To replicate the problem
-Run the Telerik Demo
-Grid View > Hierarchy > Tabbed Views
-Page View Mode = Explorer Bar
-Expand/Collapse twice the child data
-a hanging messagebox appears "RadControls for Winforms Q2 2011 SP1 Demo Application"

it also happened to my project.

EDIT: I attached a screenshot

Usando SQLDataReader para llenar un GridView

Hola a todos:

Escribo en español, porque mi inglés no es muy bueno. De igual forma, espero que puedan ayudarme.
Tengo un GridView y quiero llenarlo con datos desde un Store Procedure, mediante un SWLDataReader. Al ejecutar la aplicación, me muestra la cuadrícula del Grid, pero no se visualiza ningún dato.

Este es el procedimiento que llena (o por lo menos trata) el grid.

Friend Sub LlenaDatosIniciales(ByVal FechaIni As String, ByVal FechaFin As String, ByVal gvArt As RadGridView)

cmdComProv.Connection = cnnConexion

cmdComProv.CommandText =

"EXEC superCompraVenta '" & FechaIni & "','" & FechaFin & "',1"

If cnnConexion.State = ConnectionState.Open Then

cnnConexion.Close()

End If

cnnConexion.Open()

rdrComProv = cmdComProv.ExecuteReader

gvArt.MasterTemplate.LoadFrom(rdrComProv)

cnnConexion.Close()

End Sub

Saludos
Ruben

Filter display format issue

Hi,

How to set Culture Info for a filter on a GridViewDateTimeColumn ? The columns culture is set to "en-US" and the dates are displayed in mm/dd/yyyy format. But, when I use the filter on this column, the filter drop down shows values in dd/mm/yyyy format. I have attached the screen shot highlighting the problem.

Thanks,
Venkat

I have a few listviews, each bound to a generic list of a simple class. When the user clicks a button I want to remove an item from one list and add it to another. I am able to do this just fine but the listview does not refresh it's contents. What is the method required to rebind or reload the bound data?

Miltiple aims hierarchical grid issue

Current Version we are using is Q2 2010 SP1 Version 2010.2.10.713. We are facing the following issue:

In grid CellEndEdit, we perform some operation on the current item of the binding source and then trying to reset it. When we use ResetBindings(), it throws the null reference (PFA) and when we use ResetCurrentItem() or ResetItem(), it throws index out of range exception (but the item which we are trying to reset is present in the binding source).

1. If we use ResetBindings() on a text box inside the child grid:
An unhandled exception occurred, and the application is terminating. For more information, see your Application event log.

Vertical Scroll Bar Problem

Hi Telerik,

Thanks for the awesome jobs in releasing Q2. I solved many of my problems.

But I face this problem:
I set the grid autoscroll=false, autosize=fill and verticalscrollstate=autohide,

When i add data into grid the vertical scroll bar will show althought it's not needed. And when i scroll the vertical scroll the scroll is dissappear. How to make it appear when only needed?

I can confirm that the size of the grid is not limited the area. Thank again
