Localization of RibbonView QuickAccessToolbar menu

Hi,

I would like to show the RibbonView menu entries for customizing the Ribbon in a WPF application in German but found the documentation a little confusing.

>I copied Telerik.Windows.Controls.resources.dll into a de subdirectory of my referenced assemblies.

Do I still have to set the Current Culture? (I did but with no sucess).

The Silverlight documentation says something about a config file.

As I understand the entries should automatically in German (right now they are displayed in English).

Kind regards,
Peter

RadGridView perfomance issues as number of rows incresed

Hi,

In my wpf application i am using tab control. In first tab i am using list box to show the data and in second tab i am using rad Grid View to show data.

After loading both tabs when i switch the tab from grid view tab to list box then there is no delay in loading that view but when i switch back to the previous tab (Grid View) it takes some delay to load the data .

It seems like when number of rows increses in Rad grid view it creates some performance issues.

In tab switching it should not be a problem if we have loaded it already as it works perfect in listbox.

Is there any property to prevent this repopulation of rad grid view.

Looking forward for your reply .. It is really urgent.

Thanks

Displaying GridViewImageColumn

Hi
I am creating a gridview columns programmatically (see code below).

Everything is working fine except for a GridViewImageColumn which is not displaying although the data seems to be bound correctly. I am using the following for testing:

Database: Northwind
Table: Categories:
Column: Picture
SqlServerType image
System.DataType: Byte[]

Thanks
Rich

if (col.DataTypeName == "image")

{

GridViewImageColumn imageCol = new GridViewImageColumn();

imageCol.DataMemberBinding = new Binding(col.ColumnName);

imageCol.Header = col.ColumnName;

if (col.IsHidden == true)

imageCol.IsVisible = false;

imageCol.UniqueName = col.ColumnName;

imageCol.DataType = Type.GetType(col.SystemDataType);

imageCol.FilterMemberType = Type.GetType(col.SystemDataType);

gridQueryResult.Columns.Add(imageCol);

}

else

{

GridViewDataColumn dataCol = new GridViewDataColumn();

dataCol.DataMemberBinding = new Binding(col.ColumnName);

dataCol.Header = col.ColumnName;

if (col.IsHidden == true)

dataCol.IsVisible = false;

dataCol.UniqueName = col.ColumnName;

dataCol.DataType = Type.GetType(col.SystemDataType);

dataCol.FilterMemberType = Type.GetType(col.SystemDataType);

gridQueryResult.Columns.Add(dataCol);

}

Tile's Invisible after applying Group Template

I tried applying Michael Crump's Blog Post, here, to my own code. Particularly the Group Template stuff. I now have two Groups shown but my Tiles all disappeared.

GridView + RadContextMenu = Designer Failure

As the title mentions the GridView for some reason (not sure when it started), will only accept System.Windows.Controls.ContextMenu as its contextmenu in the design time environment. Even though the documentation states RadContextMenu was viable.

Also it doesn't not take on the Theme set...

Title Amendment... Designer doesn't fail per se, but merely indicates that the RadContextMenu is correct type for use with the RadGridView very much contradicting the documentation. Therefore a bug imo.

File Browser Dialog as Custom DataFormDataField

Hello All,
I just wanted to submit a solution I found that allows me to attach a file browser dialog to a textbox field of a data form (see attached example1.png). Basically I wanted a browse button next to the text box that would open a filedialog and replace the textbox's text property with the selected file's path. I found this cool class in a blog post ( blogpost ) that allow someone to attach a filebrowser dialog to a textbox and re-engineered it in VB.NET (see the blog posting for the C# version). I then created a User Control that contains the button and textbox and attaches to a custom filter field. Next I created a class call DataFormImageFileBrowser that Inherits from the DataFormDataField and replaces the textbox with the user control. Finally I bound the custom DataFormDataField in the AutoGeneratingField event and viola it works... here my code for the OpenFileDialogEx and the DataFormImageFileBrowser

Imports System

Imports Microsoft.Win32

Imports Telerik.Windows

Imports Telerik.Windows.Controls

Public Class OpenFileDialogEx

Public Shared ReadOnly FilterProperty As DependencyProperty = DependencyProperty.RegisterAttached("Filter", GetType(String), GetType(OpenFileDialogEx), New PropertyMetadata("All documents (.*)|*.*", Sub(d, e) AttachFileDialog(DirectCast(d, TextBox), e)))

Public Shared Function GetFilter(element As UIElement) As String

Return DirectCast(element.GetValue(FilterProperty), String)

End Function

Public Shared Sub SetFilter(element As UIElement, value As String)

element.SetValue(FilterProperty, value)

End Sub

Private Shared Sub AttachFileDialog(textBox As TextBox, args As DependencyPropertyChangedEventArgs)

Dim parent = DirectCast(textBox.Parent, Panel)

''added this because there was a problem with double binding and it was causing the filebrowser dialog to pop up twice

Dim tag = TryCast(parent.Tag, String)

If Not IsNothing(tag) Then Return

parent.Tag = "already bound"

AddHandler parent.Loaded, Sub()

Dim button = DirectCast(parent.Children.Cast(Of Object)().FirstOrDefault(Function(x) TypeOf x Is Button), Button)

Dim filter = DirectCast(args.NewValue, String)

AddHandler button.Click, Sub(s, e)

Dim dlg = New OpenFileDialog()

dlg.Filter = filter

Dim result = dlg.ShowDialog()

If result = True Then

textBox.Text = dlg.FileName

End If

End Sub

End Class

Public Class DataFormImageFileBrowser

Inherits DataFormDataField

Protected Overrides Function GetControlBindingProperty() As DependencyProperty

Return TextBox.TextProperty

End Function

Protected Overrides Function GetControl() As Control

Dim fd = New OpenFileDialogUC("Image file (pdf,png,gif,jpg,bmp,tif,emf,wmf)|*.pdf;*.png;*.gif;*.jpg;*.bmp;*.jpeg;*.tiff;*.tif;*.emf;*.wmf")

Dim dependencyProperty As DependencyProperty = GetControlBindingProperty()

If Not IsNothing(DataMemberBinding) Then

Dim binding = DataMemberBinding

fd.FileNameTbx.SetBinding(dependencyProperty, binding)

End If

Return fd

End Function

End Class

Here is the code for the UserControl:

<UserControl x:Class="OpenFileDialogUC"

xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

xmlns:d="http://schemas.microsoft.com/expression/blend/2008"

xmlns:src="clr-namespace:CarWashInventoryManagement"

mc:Ignorable="d" >

<Grid>

<Grid.ColumnDefinitions>

<ColumnDefinition Width="*"/>

<ColumnDefinition Width="Auto"/>

</Grid.ColumnDefinitions>

<TextBox x:Name="FileNameTbx" MinWidth="100" src:OpenFileDialogEx.Filter="{Binding FilterStr}" Grid.Column="0" />

<Button Grid.Column="1">Browse</Button>

</Grid>

</UserControl>

and its code behind:

Public Class OpenFileDialogUC

Public Property FilterStr As String = String.Empty

Public Sub New(_filter As String)

FilterStr = _filter

DataContext = Me

InitializeComponent()

End Sub

End Class

here is the code for the AutoGeneratingField for the RadDataForm

ElseIf e.PropertyName = "FileName" Then

Dim df = New DataFormImageFileBrowser()

df.Label = e.DataField.Label

df.DataMemberBinding = e.DataField.DataMemberBinding

e.DataField = df

e.DataField.Label = "File Name"

I thought this was pretty cool so I thought I would share...

RadDocking SaveLayout issue

Hi,

we've got an issue with the saving functionality of RadDocking.
When I call the RadDocking.SaveLayout() function, it will create a xml like (this is a snippet from the whole file):

<RadSplitContainer Dock="DockedTop" Orientation="Vertical">

<Items>

<RadPaneGroup RelativeWidth="100" RelativeHeight="100" SplitterChange="422,180833333333" SelectedIndex="0">

<Items>

<RadPane SerializationTag="LineAppearancesPane" IsDockable="True" />

</Items>

</RadPaneGroup>

<RadPaneGroup RelativeWidth="100" RelativeHeight="300" SplitterChange="554,5425" SelectedIndex="0">

<Items>

<RadPane SerializationTag="CallControlWheelPane" IsDockable="True" Header="" CanFloat="False" />

</Items>

</RadPaneGroup>

</Items>

</RadSplitContainer>

When I do a loadLayout based on this XML, one of our panes is completely hidden, it looks like it is out of the screen. However, when I change the SplitterChange to 422, it's working correctly again. So it looks like a problem with the huge number of digits within that SplitterChange.

So far, this problem only occurs on the machine of a tester, I couldn't reproduce a savelayout which would give me such a strange splitterchange as well. However, when I load his settings on my machine, I've got the same issue, so it must be in the xml, and somewhere in the savelayout.

We are running RadControls for WPF v.2013.1.220.40
Is this a known issue, or a quick solution/workaround for it? I could read the xml string again and change all SplitterChange values to integers as a temporary workaround, but prefer a more robust solution ;)

Thanks in advance,
Rutger

Custom tool configuration

Hello,
I've started creating custom tool based on resize tool, however I'd like to have:
a) press button -> tool is runnig and changes are applied to image
b) no tool settings window is displayed.

Currently tool settings window with reset button is diplaying (I do not need that)
And Tool is not commiting itself. I would like to automatically commit changes similar to flip or rotate.
