Changing IsLogarithmic on Y Axis at run time

Hi,

I've added an option on my RadChart to toggle between the Y-axis being logarithmic & non logarithmic. This is at run time so a user can flick between the two after the data has been plotted.

I'm seeing some funny behaviour with points not appearing where they should. Before looking into this further I wanted to check if I should be clearing down the series and re drawing them whenever I change the value of IsLogarithmic on the Y-axis?

Any help is much appreciated.

Thanks,

Rob

PDFViewer busy indicator (loading image) doesn't get cleared when a null values is set to DocumentSource

Steps:
1. Add a pdf viewer to code (see the attachement for the markup)
2 Set SelectedFilePath property to a valid file name
3. Pdf viewer displayed the loading image
4. Before it completes the file load, change SelectedFilePath property to null
5. Pdf viewer keep displaying the loading image (it doesnt get cleared).

As I checked, the Pdf viewer's loading image is cleared only when the pdf file is loaded, but not when a Document=null is set (if it was displaying the image).

Can you please check whether I have a solution to the problem

Hide Cell Content Based on Condition

For certain rows I don't want the cell to be editable or show any content. Maybe focusable but user wouldn't be able to go into edit mode. This behavior would be based on a value of the row's data context. Essentially, certain attributes don't apply to certain rows, so user shouldn't be able to interact with those columns at all.

How can you go about doing this that doesn't require that I recreate the data template?

Styling GridViewDataColumns and GridViewSelectedColumns in RadGridViews

Greetings Telerik,

I have multiple RadGridViews which consist of both GridViewDataColumns as well as GridViewSelectColumns. Is there a way I can set the style for each column type once and have it apply to all RadGridViews?

If I include this style in the resources section of my application's MainWindow, it works fine and all cells will receive the styling I desire:

<Style TargetType="{x:Type telerik:GridViewCell}">
    <Setter Property="VerticalContentAlignment" Value="Top"/>
</Style>

However that will affect checkboxes in GridViewSelectColumns which I would like to remain "centered" regarding their VerticalContentAlignment... so I tried this (also in the resources section of my Mainwindow):

<Style TargetType="{x:Type telerik:GridViewDataColumn}">
    <Setter Property="CellStyle">
        <Setter.Value>
            <Style TargetType="{x:Type telerik:GridViewCell}">
                <Setter Property="VerticalContentAlignment" Value="Top"/>
            </Style>
        </Setter.Value>
    </Setter>
</Style>

However it does not seem to apply the styling to any cells... But, if I go to each column in each grid and set the style manually (using the same style) for each one it does work:

<Style x:Key="myStyle"  TargetType="{x:Type telerik:GridViewCell}">
    <Setter Property="VerticalContentAlignment" Value="Top"/>
</Style>

<telerik:RadGridView
            x:Name="mygridview"
            ShowGroupPanel="False"
            ItemsSource="{Binding Path=MyView}"
            AutoGenerateColumns="False"
            SelectionMode="Extended"
            SelectedItem="{Binding Path=SelectedRecord}"
            RowIndicatorVisibility="Collapsed"
            CanUserFreezeColumns="False"
            CanUserDeleteRows="False"
            ScrollMode="Deferred">
    <telerik:RadGridView.Columns>
        <telerik:GridViewSelectColumn />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=RecordName}" CellStyle="{StaticResource myStyle}" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=RecordName}" CellStyle="{StaticResource myStyle}" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Path=RecordName}" CellStyle="{StaticResource myStyle}" />
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

Any advice you could provide would be greatly appreciated. I'm using .NET 4.5.1 with Telerik UI for WPF Q3 2013 SP2 (13.3.1316.0) in Visual Studio 2013. Thanks!

Cheers,
Beau

Upgrade DLLs and Get Build Error

Got the latest DLL only dev build of the WPF controls, dropped the DLLs into my project folder, clean, rebuild and get
Error 1 The name "RadWindow" does not exist in the namespace "http://schemas.telerik.com/2008/xaml/presentation".

Did the namespace change?

Why would updating the DLLs cause this?

Any help appreciated.

Changing the FilterOperators

I was wanting to know if there was a way to add to the FilterOperator enums or change what they display as. If those were not possible, can I override the operators dropdown with my own collection?

Closing events for multiple floating RadWindows

Hi, I've made a modal dialog using RadWindow (W1), and had another RadWindow (W2) pop up from W1.
What I want to do is when I close W2, W1 should get notified of the closing event of W2, but currently as far as I know, this is impossible.
Please help me!
