Hi.

<

telerik:RadGridView.RowDetailsTemplate>

<DataTemplate>

     <telerik:RadGridView Margin="4,5,5,4" ShowColumnFooters="False" ShowGroupPanel="False" AutoGenerateColumns="False" ShowInsertRow="False" ItemsSource="{Binding IoTerminals}">

     <telerik:RadGridView.Columns>

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

        <telerik:GridViewCheckBoxColumn Header="Simulated" DataMemberBinding="{Binding Simulated}"/>

         <telerik:GridViewCheckBoxColumn Header="Sim is possible" DataMemberBinding="{Binding SimPossible}" />

    </telerik:RadGridView.Columns>

    </telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView.RowDetailsTemplate>

(Edit: I have made two edits on this post to try to make the above xaml look approachable, but to little avail)

The two Checkbox columns shows up empty. In the debugger I see that the property "SimPossible" is executed correctly and that it return "true". The "Name" column shows the correct value (boolean True).
If I change AutoGenerateColumns to True, then the additional generated columns shows correct value (and checked status).
No binding error is displayed in the debugger output window.

Is there any further parameterization necessary to map boolean "True" to display checked status? Do I need a value converter?

As you can see, this is in the rowdetails section of another GridView (in case that is relevant).

(New Info : Replacing the GridViewCheckBoxColumn with regular GridViewDataColumn is displayed correctly)

I use Q1 2012.

 

I am using RadTreeListView control to display data as a hierarchical view. I am binding my entity collection to the control using ItemSource, and my entity collection is of type ObservableCollection<T>. Whenever some data is changed in the source collection, i am performing an ItemSource again on the control. This is leading to losing all the expand/collapse state of the control. Thats is, as soon as I bind the new data (ItemSource), it updated the data but closes the expand/collapse state. How can I maintain the expand/collapse state of control even after ItemSource.

Hello,

I have a radgridview which i have bind to an ObservableCollection<objects>.
Now i want to insert a new row. I Have the following columns - Countryid | CountryName | Currency.

For the countryid and name i just type in some value in the cell...as for the Currency...i get the value from lookup.

When i double click on the cell Currency - i have a Search screen from which i select the currency.

Now the issue is that on closing the search screen , i can't return the value to the cell Currency.

Does anyone know how we can do this ?
i was trying to set the value of current cell but it did nt work.
gvcountries.Currentcell.Value = "text";

Please giv some hints on how i could tackle this.

Shaimaa

When binding the RadListBox, the list items have a gray foreground color on load. It is only until I mouse over each item that they turn to black. After the mouse over it is working fine.

My Listbox is:

<telerik:RadListBox x:Name="lb1" Width="116" HorizontalAlignment="Left" IsEnabled="True" telerik:StyleManager.Theme="Windows7" ItemsSource="{Binding}">

               <telerik:RadListBox.ItemTemplate>

                   <StaticResource ResourceKey="Template1"/>

               </telerik:RadListBox.ItemTemplate>

           </telerik:RadListBox>

DataTemplate:

<Grid.Resources>

                <DataTemplate x:Key="Template1">

                    <WrapPanel>

                        <Grid>

                            <Grid.RowDefinitions>

                                <RowDefinition Height="20"/>

                            </Grid.RowDefinitions>

                            <Grid.ColumnDefinitions>

                                <ColumnDefinition Width="*"/>

                                <ColumnDefinition Width="*"/>

                            </Grid.ColumnDefinitions>

                            <TextBlock Grid.Column="0" Text="{Binding Path=A1}"/>

                            <TextBlock Grid.Column="1" Text="{Binding Path=B1}" Margin="4,0,0,0"/>

                        </Grid>

                    </WrapPanel>

                </DataTemplate>

            </Grid.Resources>

Hey,

Was labbing some this morning and i come over this.

   <telerik:GridViewDataColumn Header="LogistikID" DataMemberBinding="{Binding nOrderID}" />
   <telerik:GridViewDataColumn Header="Namn" DataMemberBinding="{Binding strDisplayName}"/>
   <telerik:GridViewDataColumn Header="CareOf" DataMemberBinding="{Binding strCareOf}"/>
   <telerik:GridViewDataColumn Header="Gata" DataMemberBinding="{Binding strAddress}"/>
   <telerik:GridViewDataColumn Header="" />


If i leave one column not binded the Gridview lags like hell.

Im pretty sure i have to bind them all because i use GridViewDataColumn, but is it realy gonna lag so bad?

If i leave it empty, Shouldn't it just be ignored?

If i bind the last GridViewDataColumn it's lag free while scrolling/filtering.

Bug or Feature?

I found an old forum thread describing the problem, but its from 2009.

Within a DataTemplate I have GridView.
Within the same datatemplate I have a button where I want to do a bulk operation on the filtered set of items.
The datacontext of the DataTemplate is an INotifyPropertyChanged derived object, which provides the GridView ItemsSource.

How do I, when handling the button click, obtain the list of filtered items back from the RadGridView?

The DataTemplate is hosted within the body of a data driven RadTabControl, if it matters.

Dear Telerik team,

i'm using a RadScheduleView Control, with Appointment Templates as used in your examples/demos (works great).
Now i want to extend the show duration of a tooltip from an appointment.

Per default it's set to 5-6 seconds, but i need it at least for 20 seconds.

I read in your forum that this can be done by setting the ToolStipService ShowDuration

eg.:
ToolTipService.ShowDuration="20000"

I tried to set his in the control template of the "root" Grid, but it doesn't work.
Can you tell me how to set this property to take this effect, or is there another configuration needed ?

eg.: Horizontal Style for an Appointment


best regards
rudi

Hi,

I have a RadGridView, depending of the grid type I need, I build dynamically each columns and each aggregate functions. Each time I build a grid, at least one decimal column exist. For othe aggregate functions than SUM, it work...
 
When I assign the ItemSource to the array of objects I receive from the back-end, I receive the following message: "Aucune méthode 'Sum' sur le type 'System.Linq.Enumerable' n'est compatible avec les arguments fournis."

xaml:

Hello,
I am using RadToolbar with ItemsSource.
Here is code:

ItemTemplate:

When I add elements to ExtToolbarButtons collection I see normal - styled buttons.
How to use ItemsSource with  telerik - styled buttons on RadToolbar?

This code used to work with an older Telerik release (can verify the version if need be), but no longer works with the latest (RadControls_for_WPF_2012_1_0215_Dev).

Steps to reproduce:
1. Right-click and select the context menu item to add a top-level row.
2. Right-click the row and select the context menu item to add a child row.
3. Right-click the child row, and you get the exception.

TreeListViewRow.ParentRow throws an exception because it tries to do "var parentView = this.Items.ParentView;" but Items is null.

Each top-level (parent) row contains a ParentItem object with a ChildItems property, and the ChildTableDefinition is bound to the ChildItems property. Each child row contains a ChildItem object, which doesn't have a ChildItems property, so when it tries to get the child items for a child row, the collection is null. As a workaround, if I give the ChildItem class a ChildItems property and have it return an empty collection, then the exception goes away. I'm no telerik expert, but it seems strange to me that a row needs to have a non-null collection of child items in order to access the row's parent row.

Apparently you don't let users upload test projects, so here's the source:
