Hi There

I have a menu which contains a gridview, I cant seem to drag column headers to the group header though when in that menu. The menu just dissappears. Code for the grid below:

<telerikGridView:RadGridView x:Name="radGridAssets" Grid.Column="0" Grid.Row="0"

Margin="0" ShowGroupPanel="True" VerticalAlignment="Stretch" HorizontalAlignment="Stretch"

ShowInsertRow="False" RowIndicatorVisibility="Collapsed"

AutoGenerateColumns="False"

ItemsSource="{Binding FullAssetList}">

<!--<telerikGridView:RadGridView.GroupDescriptors>

<telerikData:GroupDescriptor Member="SiteName" />

</telerikGridView:RadGridView.GroupDescriptors>-->

<telerikGridView:RadGridView.SortDescriptors>

<telerikData:SortDescriptor Member="SiteId" SortDirection="Ascending" />

<telerikData:SortDescriptor Member="OrderByProcessType" SortDirection="Ascending" />

</telerikGridView:RadGridView.SortDescriptors>

<telerikGridView:RadGridView.Columns>

<telerikGridView:GridViewDataColumn Header="" Width="Auto">

<telerikGridView:GridViewDataColumn.CellTemplate>

<DataTemplate>

<CheckBox x:Name="chkSelectedAsset" IsChecked="{Binding IsSelected, Mode=TwoWay}"

Unchecked="chkSelectedAsset_Unchecked" Checked="chkSelectedAsset_Checked" />

</DataTemplate>

</telerikGridView:GridViewDataColumn.CellTemplate>

</telerikGridView:GridViewDataColumn>

<telerikGridView:GridViewDataColumn Header="Site" DataMemberBinding="{Binding SiteName}" IsReadOnly="True">

<telerikGridView:GridViewDataColumn.GroupHeaderTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal" >

<TextBlock Text="{Binding Group.Key}" />

<Button x:Name="buttAssetGridSelectAll" Margin="5,0,0,0" Content="All" FontSize="10" Tag="{Binding Group}" Click="buttAssetGridSelectAll_Click" />

<Button x:Name="buttAssetGridSelectNone" Content="None" FontSize="10" Tag="{Binding Group}" Click="buttAssetGridSelectNone_Click" />

</StackPanel>

</DataTemplate>

</telerikGridView:GridViewDataColumn.GroupHeaderTemplate>

</telerikGridView:GridViewDataColumn>

<telerikGridView:GridViewDataColumn Header="Asset Name" DataMemberBinding="{Binding AssetName}" />

<telerikGridView:GridViewDataColumn Header="Process" DataMemberBinding="{Binding ProcessType}" />

<telerikGridView:GridViewDataColumn Header="SiteId" DataMemberBinding="{Binding SiteId}" IsReadOnly="True" IsVisible="False" />

<telerikGridView:GridViewDataColumn Header="OrderBy" DataMemberBinding="{Binding OrderByProcessType}" IsReadOnly="True" IsVisible="False" />

</telerikGridView:RadGridView.Columns>

</telerikGridView:RadGridView>

QualitativeRange Error on Binding

Hello,

in my scenario i try to visualize the variance of a production cyle within a radgridview. For this i want to show a warning/error range.

<telerik:RadHorizontalBulletGraph Width="150" Height="20"

QuantitativeScaleVisibility="Collapsed"

FlowDirection="LeftToRight"

FeaturedMeasure="{Binding Input0TimeLast}"

ComparativeMeasure="{Binding Auftrag.ZyklusIstSoll}">

<telerik:RadHorizontalBulletGraph.QualitativeRanges>

<telerik:QualitativeRange Brush="Red" Value="{Binding ZyklusErrorBound}" />

<telerik:QualitativeRange Brush="Yellow" Value="{Binding ZyklusWarningBound}" />

<telerik:QualitativeRange Brush="Green" Value="{Binding ZyklusOkBound" />

</telerik:RadHorizontalBulletGraph.QualitativeRanges>

</telerik:RadHorizontalBulletGraph>

public int ZyklusErrorBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - this.Auftrag.ZyklusIstToleranz;

return x;

}

public int ZyklusWarningBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - (this.Auftrag.ZyklusIstToleranz / 2);

return x;

}

When i bind the three QualitativeRange`s i get a exception "Sequence contains no elements". If i set instead of ZyklusOkBound a fixed value for example, no exceptions is thrown. But the two other values are not called from my Itemssource (i´ve checked that by setting a breakpoint on my getters). Instead of a message shows up in my console:

System.Windows.Data Error: 2

:
Cannot find govening FrameworkElement or FrameworkContentElement for
target element. BindingExpression:Path=ZyklusWarningBound;
DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

System.Windows.Data Error: 2

: Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=ZyklusErrorBound; DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

What is absolutely remarkable, if i bind ZyklusErrorBound or ZyklusWarningBound to FeaturedMeasure the value is retrieved..

Thanks in advance for your help.

Map freezes

Hi,
I'm testing RadMap. I build a window with a radmap and a listbox with locations (based on your samples).
After a few changes in the listbox, the window freezes. I must then stop the process from visual studio.
Bassically, i had a code like this:

private void listBox_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

ListBox lista = sender as ListBox;

if (lista.SelectedItem == null) return;

destino = (Location)lista.SelectedItem;

this.radMap1.Center = destino;

}

I tried in debug and in release modes.
I tried with both providers, bing and open.
If I use a 'zoom effect' like in your samples (changing the last line to "ZoomOut();") the freezes occurs after 5-10 changes in the listbox. If I use the showed code, the freezes occurs after 10-50 changes.

Thanks in advance, and excuse me if my english is not good.

ShowsConfirmationWindowOnDelete

we used to have

ShowsConfirmationWindowOnDelete

property in RadScheduler, what is the counterpart of that property in ScheduleView? I noticed that Deleting events gets fired AFTER confirmation dialog is shown, so I cannot override it by e.Cancel=true...

Please advise

What is the proper way to set column widths in the GridView

Hi,

We are using a GridView, and I am having difficulty getting the column widths to work how I think they should. It seems like it should be simple.

I am reading the widths from a config file as a double and calling a converter, and want to save them out there when the app closes. This is pretty simple. The issue is that if I bind the column width to the config setting, it gets overwritten as soon as resize happens (but I do get the calls to resize), I believe because ColumnWidth is set to sizeToHeader for the grid. If I put the binding on the header, I don't seem to get a notification (my converter isn't called) when the column is resized. I am simply looking for the correct method of setting this up so that when the column is resized, I get notified, and my headers and columns stay in sync. Let me know if a code sample would help.

Thanks,

Anthony.

ApplicationCommands

I've got a ribbon with the standard Copy, Paste, Cut buttons on them. .

    
            <telerik:RadRibbonButton Text="Cut" Size="Medium" />

As soon as I assign a command the buttons disable. I would have expected it to simply use the built-in Cut command.

    
            <telerik:RadRibbonButton Text="Cut" Size="Medium" Command="ApplicationCommands.Cut"/>

What I get however is a disabled Cut button. What am I missing?

Building docking windows

I am new to wpf and have most of my experience in programing windows forms. I am looking for some help achieving a solution. I have a main control panel window i have created for my company. What i am looking for is to be able to click on a button on this UI and have a new window slide out from behind it containing a new window that have created with different controls on it. Both these files are their own xaml files.
