Controlling portions of the Radsplitbutton

Hi,
I've recently started using Rad controls for WPF in Powerbuilder .NET 12.5

I'm using powerscript to control most of the basic events within my Radbuttons (such as open / close windows, set text labels, etc.)

The issue I'm having is getting full control of the Radsplitbutton.

For example, I currently have a radsplitbutton1 where isOpen = true when the MouseEnter event occurs. I can also use AutoOpenDelay to achieve the same result.

However, I cannot find any way to close the popup. I've tried putting isOpen = false into the MouseLeave and LostFocus events, but it never closes. And there doesn't seem to be anything similar to AutoOpenDelay which will close the popup instead of open it.

Also, the AutoOpenDelay seems to cover the entire button. I'm not sure if there is a way to open the popup ONLY when the mouse is on the drop down arrow?

<ESCAPE> doesn't always exit editing - should it?

I have a grid bound to an Entity Framework-based CollectionViewSource.

For the sake of this example, my columns (left->right) are:

Name - in the database this is required, unique, and non-Null
Serial # - a string

I'm getting an exception when trying to escape editing a new line

Press <click here to add new item>
Type in a name
press <TAB> to advance to serial # column and type in a serial number
press <BACKTAB> to move focus to Name column
delete everything in the Name field that you just entered
Press <ESCAPE> once

My Entity Framework code throws an exception in the Device.Name property setter because it's been passed a Null.

I was under the impression that pressing <ESCAPE> was supposed to exit editing mode and pressing it twice on a new line was supposed to discard it. That (the latter) does happen if I've entered no data in the columns or valid data. If I continue (and ignore the exception), the new row is discarded, but I'm concerned because I don't understand what's happening.

When pressing <ESCAPE>, neither the row or cell validation methods are called, which makes sense.

Why is the RadGridView attempting to update the underlying data when it's about to be discarded?

Maintain scroll position on treelistview page navigation

Hi,

I need to maintain scroll position (both horizontal and vertical) when moving across pages.
I tried the following code , but was unable to achieve the desired functionality.
Even after calling RestoreScrollPosition() the scrollviewer didn't change its position.

private void btnNext_Click(object sender, RoutedEventArgs e)

{

SetScrollPosition();
BindData();

RestoreScrollPosition();

}

private void SetScrollPosition()

{

GridViewScrollViewer svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();

_dbVerticalOffset = svSummaryInfo.VerticalOffset;
_dbHorizontalOffset = svSummaryInfo.HorizontalOffset;
}

private

void RestoreScrollPosition()

{

GridViewScrollViewer

svSummaryInfo = (GridViewScrollViewer)rtSummaryInfo.FindChildByType<GridViewScrollViewer>();

if (svSummaryInfo != null)

{

svSummaryInfo.ScrollToHorizontalOffset(_dbHorizontalOffset);

svSummaryInfo.ScrollToVerticalOffset(_dbVerticalOffset);

}
}

Please provide a code snippet for the same.

Cannot get [Display(AutoGenerateFilter = false)] to work

I'm trying to use the simple example code here: http://www.telerik.com/help/wpf/raddatafilter-features-data-annotations.html

I can't get any of the data annotations to work. Here is the code I'm using:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.ComponentModel.DataAnnotations;

namespace namespace

{

public class dummy

{

[Display(AutoGenerateFilter = false)]

public string Name

{

get;

set;

}

[Display(ShortName = "Company's Name")]

public string CompanyName

{

get;

set;

}

public string Title

{

get;

set;

}

The XAML is simply <telerik:RadDataFilter Name="DataFilter" />

My application will be separated in modules, and I want to each module check for newest version, download and install it automatically.
The application is goning to run in our intranet, not internet like demos.
I was seeing demos source but it's a bit complicated, I would like to see a simplest example, some links with more information!

Thanks in advance!

Styling the RadTimePicker

I am styling the RadTimePicker so that it looks and feels the same as the rest of my application.
I am trying to style the DateTimePickerClock that is displayed when you want to select a time.
I cannot figure out how to change the highlight color for the Items (the times) displayed in the clock.
Right now when I hover over an item it is highlighted as Yellow but since the application's colours are black, blue and grey, this doesn't fit in with the colour scheme at all.

Thank you for your help,

-Rebecca

ToolTip text of HorizontalSplitter is not translated

Hello,

the ToolTip text "Start dragging in order to change items' position" is not translated in german culture.

OutlookBar_style.xaml:

...

<ToolTipService.ToolTip>

<TextBlock Text="Start dragging in order to change items' position"

telerik:LocalizationManager.ResourceKey="OutlookBarHorizontalSplitter" />

</ToolTipService.ToolTip>

...

As workaround I tried to set the ToolTip-Text by setting the HorizontalSplitterStyle like this:

...

<UserControl.Resources>

<Style x:Name="OutlookBarHorizontalSplitter" TargetType="Thumb">

<Setter Property="ToolTip" Value="My localized Text"/>

</Style>

</UserControl.Resources>

<Grid>

<telerik:RadOutlookBar x:Name="MenuOutlookBar"

HorizontalSplitterStyle="{DynamicResource OutlookBarHorizontalSplitter}">

...

Unfortuately after this the whole Style of the HorizontalSplitter is lost and the Tooltip is still default.

Please let me know if there is a solution for this issue.

Regards
Rainer
