[Solved] How to get horizontal scrollbar in a RadGridView in a window with Auto Width

Hi,

I have an application in which we haven't defined width and height for the windows or controls, instead we used Auto and * mostly for control size. To make the screen design fluid and support multiple display sizes.

I am facing an issue in showing a horizontal scroll bar for my RadGridView which is placed inside panel with no width and height defined. I have defined Auto and * as the Column's width in gridview.

My requirement is that a scroll bar should appear when the content of the grid take more space than the space available on the screen. But currently the content is clipped and no scrollbar appears (see screenshot attached).

The code I am using is:

<Grid x:Name="LayoutRoot">

<telerik:RadExpander IsExpanded="True">

<DockPanel>

<telerik:RadDataPager DockPanel.Dock="Bottom"/>

<telerik:RadGridView x:Name="billDataGrid" AutoGenerateColumns="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Ship To Bill To ID" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding BillToID}"/>

<telerik:GridViewDataColumn Header="Ship To ID" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding ShipToID}"/>

<telerik:GridViewDataColumn Header="Bill TO ID" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding ID}"/>

<telerik:GridViewDataColumn Header="Bill To Name" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Name}"/>

<telerik:GridViewDataColumn Header="Bill To Address1" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address1}"/>

<telerik:GridViewDataColumn Header="Bill To Address2" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address2}"/>

<telerik:GridViewDataColumn Header="Bill To Address3" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address3}"/>

<telerik:GridViewDataColumn Header="Bill To Address4" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address4}"/>

<telerik:GridViewDataColumn Header="Bill To Address5" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address5}"/>

<telerik:GridViewDataColumn Header="Bill To Address6" Width="Auto" TextWrapping="Wrap" DataMemberBinding="{Binding Address6}"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</DockPanel>

</telerik:RadExpander>

</Grid>

Please help me getting a scroll bar.
Thanks.

DataBinding RadRichTextBox to the ViewModel from DataBase

Hello Telerik team
Let’s say I want to do a mail merge using your awesome WPF RadRichTextBox, but as you know, a regular mail merge will include data coming from a database.
i have search, and search your documentation and forum, but the provided information is very vague , even considering that most users will use the mail merge feature with data coming from a database.
And assume i have an Observable Collection (or BindableCollection for that matter) on the view model 'public ObservableCollection MyCollection"
Considering all your dataProviders and such (yes I also read about that) , how i can read data from my database into the radTextBox so i can do mail merge
The data is served by Entity Framework 6, Unit of work, Cliburn Micro and all of that, which actually does not matter because the important thing is the Observable Collection has the data i want to be bound to the telerik RadRichTextBox

Regards

[Solved] Need to disallow the drag operation while within popup on RadListBoxItem

I've got a RadListBox, and each item in it has a ToggleButton that opens a Popup that's defined in each of the list box items; so the Popup isn't shared between the items. These Popups contain controls for data entry like textboxes, checkboxes, etc. When the user clicks and drags their mouse within the Popup, the drag operation for the containing RadListBoxItem starts. This can happen in the background of the popup or when trying to select some text within some other control in the Popup, like a TextBox.

I'd like to completely stop the drag operation from ever starting when I've got this Popup open.

What's the best way to accomplish this?

Disable Track Changes Warning on Table Resize

Hi,

I have a Rich Text Box with tracking changes enabled which contains a single table from a XAMLDataProvider. When adjusting the column/row widths using the thumbs in the UI i get a confirmation dialog saying "This action will be marked as changed. Do you wish to continue?".

Is there any way to disable this warning?

Many thanks,
Chris

Apply complex filters to RadGridView

Hi,

From what have seen it's easy to apply this kind of filter to a RadGridView (Country and Capital are the columns):
Country.Contains("France") AND (Capital.Contains("Paris") OR Capital.Contains("London")) -> this will give us 1 row (France, Paris)

What about if I want to do:
Country.Contains("France") OR (Capital.Contains("Paris") OR Capital.Contains("London")) -> so I would get 2 row (France, Paris; England, London)

I read the below pages but I couldn't find a solution for this. Can I do it in some how?

FilterDescriptor Collection & Model-View-ViewModel

I'm using an MVVM approach to an application. My Window has a textbox, a button, and a grid. When i click the button, i would like it to filter the grid based on the text inputted in the textbox. I realize the grid has built in filtering, but its more than likely too complicated for our end users.

    
                <Grid> 
        
                    <Grid.DataContext> 
        
                        <Binding Source="{StaticResource MyDataContext}" Mode="OneWay"  /> 
        
                    </Grid.DataContext> 
        
                        <telerik:RadGridView  Margin="12,55,12,58" AutoGenerateColumns="True"    Name="RadGridView1" > 
        
                        <telerik:RadGridView.ItemsSource> 
        
                            <Binding Path="Records" Mode="TwoWay" /> 
        
                        </telerik:RadGridView.ItemsSource>      
        
                    </telerik:RadGridView> 
        
                    <TextBox Height="23" HorizontalAlignment="Left" Margin="16,14,0,0" Text="{Binding SearchText}" Name="TextBox1" VerticalAlignment="Top" Width="120" /> 
        
                    <Button Height="23" HorizontalAlignment="Right" Margin="0,14,61,0" Command="{Binding SearchCommand}" Name="Button1" VerticalAlignment="Top" Width="75">Button</Button> 
        
                </Grid>

Is there any way to expose the FilterDescriptors Collection via a binding property so i can add to it and apply the filter, since i don't have access to RadGridView1.FilterDescriptors in my code? This would be similar to how the textbox exposes it's text property.

Is there a way to expose the ColumnCollection or SortDescriptors?

Binding 2 controls to 1 source

Hello, I'm binding 2 TreeView controls to one source, and only 1 TreeView has data, the other is empty.
Here's my code.

radTreeview1.ItemsSource = MyClass.Children;
radTreeview2.ItemsSource = MyClass.Children;

radTreeview1 is blank. If I comment out radTreeview2, radTreeview1 displays with data, so it looks like the last item to bind will work.

Can I not use the same class to bind to 2 different controls?

Thanks,
Scott

MVVM - Control color of area series on dynamically generated graph

I am generating 2 to 4 area series dynamically by referring below link from telerik documentation:

http://www.telerik.com/help/wpf/radchartview-features-chartseriesprovider.html

But these dynamic area series are showing default colors.

Is there a property I could use to control the color of dynamically generated Area series? My application is using MVVM pattern.
