RadGridView: Binding multiple datatables

Hello,

I would like to know if its possible to bind multiple datatables to a single RadGridView? I need to bind a datatable to populate the grid and beside that I would also like to bind the column header properties.

xaml

<telerik:RadGridView Margin="0"

AlternationCount="2"

AlternateRowBackground="#d7e8ff"

AreRowDetailsFrozen="True"

AutoGenerateColumns="False"

CanUserFreezeColumns="False"

IsReadOnly="True"

ItemsSource="{Binding}"

SelectionMode="Single"

ShowInsertRow="False"

RowHeight="30"

RowIndicatorVisibility="Collapsed"

telerik:StyleManager.Theme="Office_Blue"

x:Name="Listing">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="ID" DataMemberBinding="{Binding Path=vis_ID}" IsVisible="False" Footer="Test"/>

<telerik:GridViewDataColumn Header="{Binding [str_gridview_lastname]}" MinWidth="150" DataMemberBinding="{Binding Path=vis_lastname}"></telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

cs

// Bind datatable to populate grid

Listing.DataContext = myDataTable;

// Bind column header text properties

Listing.DataContext = myColHeaderTable;

The second binding overrides the first binding. Any suggestion to bind both are welcome

Kind regards,
Dennis

[Solved] Tell me how the table cell alignment magic happens

I've got a RRTB with the RRTBRUI in my application, where table cell alignment is all botched.

(The ribbon was created by dropping the RRTBRUI on the design surface. I then removed editing options I don't want the user to have.)

To illustrate, please view the attached image. You can see that not only is 1) the context menu alignment button 2) not being respected within the design surface, but also 3) within the ribbon you can click an entire row of alignment buttons.

To try and debug this, I have

copied the exact markup into a minimal solution
compared mouse events
examined application resources
cranked wpf trace levels to ALL
Listened to RTB command events

Copied the markup exactly, and was unable to repro in a minimal solution. Damn.

I watched mouse events in both a working example and in my non-working example, and did not see events being handled any differently. Damn.

I checked to see if there were any Styles with default keys that were interfering with the RadToggleButton in any way, and had none. Damn.

Cranked up all trace levels and repro'd. Nothing. Well, actually LOTS of nothing. But 99% was binding failures before the commands binding was updated ("DataItem=null"), and the rest were about "Path=Menu.IconColumnWidth". Damn.

Listened to CommandError, CommandExecuting, and CommandExecuted. Verified the correct command and the correct command parameters are being passed every time, for every button. And CommandError never fires when using these buttons. Damn.

So that leaves me stumped. I know the RRTBRUI is doing stuff in the background, probably walking its children, managing their state. But I don't know how this is happening, so I can't figure out what is going wrong.

How does the RRTBRUI handle cell alignment? What are the things that could go wrong? Any ideas?

Mouse and Keyboard

If you mouse click a number or button and then use the keyboard to finish the calc and press enter the enter key enters the value of the selected button.

steps:
Mouse click 8
Keyboard press +
Keyboard press 5
Keyboard press Enter
Entry = 58 (Expecting 13(8+5)) (history would be 8+58 without a result because the enter key added was like pressing 8 not performing the calculation)

How to programatically sort a RadGridView

Hello, I would like to ask you a question, and I hope someone can help me, I have a WPF browser application with a RadGridView to show some data, the data source for it is an Observable collection, so when the collection changes, you can see the changes directly in the grid, but the problem is that when an item changes, it goes to the last row, and what I want to do, is after changing the element in the observable collection, order the radGridView by one of it's columns.

This is my RadGridView, and I want it to be ordered by the "Name" column

<telerik:RadGridView Margin="178,118,0,0" Name="gridAnalog" AutoGenerateColumns="False" ColumnWidth="Auto" telerik:StyleManager.Theme="Vista" CanUserDeleteRows="False" CanUserInsertRows="False" ActionOnLostFocus="None" Height="Auto" VerticalAlignment="Top" Visibility="Hidden" IsReadOnly="True" HorizontalAlignment="Left" Width="Auto">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="Name" DataMemberBinding="{Binding Key}" Width="auto"/>

<telerik:GridViewDataColumn Header="Description" DataMemberBinding="{Binding Value.Description}" Width="auto" />

<telerik:GridViewDataColumn Header="State" DataMemberBinding="{Binding Value.State}" Width="auto"/>

<telerik:GridViewDataColumn Header="Current value" DataMemberBinding="{Binding Value.Curval}" Width="auto" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

Here I set the ItemsSource property to an ObservableCollection:

gridAnalog.ItemsSource = SummaryDictionary.analogData;

And this is the function that changes the values of the observableCollection, and at the end of this function is where I want to order my Grid:

public static void updateChanges(string key, string value)

{

//Here I change an entry from the ObservableCollection

subscriberData[key] = value;

//And now I want to order

}

I have been searching through your webPage and I found this:

gridAnalog.SortDescriptors.Add(new ColumnSortDescriptor()

{

Column = gridAnalog.Columns["Name"],

SortDirection = ListSortDirection.Ascending

});

so I added this code to the function that modify the content of the observable collection:

public static void updateChanges(string key, string value)

{

//Here I change an entry from the ObservableCollection

subscriberData[key] = value;

//And now I want to order

gridAnalog.SortDescriptors.Add(new ColumnSortDescriptor()

{

Column = gridAnalog.Columns["Name"],

SortDirection = ListSortDirection.Ascending

});

}

But it doesn't work, I suppose I am doing something wrong, because when a value changes, the row goes to the las position on the grid.
Hope someone could help me, because I found a kind of article in your page named: Sorting DataGrid programatically, but the page is not working.
Thanks a lot!
