Hey,

Unfortunately I have a problem in the sort, filter and group functions in the following case:

Class A
{
string AName;
}
Class B : Class A
{
string BName;
}

Class C

{             

A baseClass;

}

 

The item source is ObservableCollection<C>
I am creating in code behind new GridViewDataColum.

If the binding is
1. " baseClass.AName" =>Everything works.
2. " baseClass.BName " =>The grid view rows are ok.All the data is shown in the correct cells,

But the Filter,Group,Sorting is not working.

 

 What can I do?

I have two RadPanes that I wish to persist only the IsPinned property of.  I wish nothing else to be persisted, how would I code this?

The two RadPanes are the only UIElements with a StorageID and their SerializationOptions are set as


When I call Load after persisting, the entire RadDock is missing.

Thank you
Scott Lee

We are using Q1 2011  SP1 telerik version. 
There is a radwatermark textbox used in a radgridview. The loaded event is not firing on double clicking the text box in the gridview.
The same functionality works with Telerik version 2010 Q3.
We are not planning to use latest 2012 telerik version due to some animation issues for our application.
Please suggest any quick solution at the earliest.

I am trying to implement a chartview with a line series. The x axis has values in miliseconds. I feel the features of the linear axis suites me more then the DateTimeCategoricalAxis but I can't seem to get it to work with linear axis in both horizontal and vertical directions. Doesn't this work? And if it does, how would I do thìs? Is there any example showing this?    

Hi

i am creating readonly ranges using the InsertReadOnlyRange method.
This works well most of the times.
However I get a NullReferenceException deeply from the tk-lib code
with the following stacktrace:

    
the line raising the exception goes like:


"Parent" is null here.
I noticed that the "null-ness" and the exception only occur if the span is inserted using InsertInline:



so my wish to the telerik developpers is to fix this line of code.
There are circumstances where a spanbox has no Parent layoutbox.
(E.g. when appending it with InsertInline). So you can't use it to get its previous sibling.
If you anaylze the stack trace and the surrounding code of "GetCaretInline"
it's fully OK to null check the Parent property and in this case simply return
the span associated to the layoutbox "currentSpanBox".

Hi,

I am using a TreeListView to display data as multi-column tree. I have set my VM as DataContext to the page and giving my VM property as the ItemsSource of the TreeListView control. When I change the underlying data in VM, it updates the data in the grid normally for the 1st time, but it never updates the data in the grid after that. I checked the data in VM is always right, but the grid never shows the update. It happens only once.

My grid code is:
<telerik:RadTreeListView x:Name="trvHierachyData" ItemsSource="{Binding Path=Data}">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                    <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                        <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                            <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Items}">
                                </telerik:TreeListViewTableDefinition>
                            </telerik:TreeListViewTableDefinition>
                        </telerik:TreeListViewTableDefinition>
                    </telerik:TreeListViewTableDefinition>
                </telerik:TreeListViewTableDefinition>
            </telerik:RadTreeListView.ChildTableDefinitions>
        </telerik:RadTreeListView>


I am setting the page data context to the VM, i.e. in page ctor - this.DataContext = vmMainControl. The VM has a property by the name of Data which is of type ObservableCollection<T>. The Data collection has Items which is a collection collection of that node.

Please let me know if I am not clear

When the view is initially loaded, the RadPanes start out open, and then immediately shut. This is visible and distracting. I really want them to just be closed from the get go.How can I make it so the RadPanes in a RadPaneGroup are initially closed (unpinned)?

hi there,

    how to i load multiple items in multiple panel bar so that it show dynamic world like we can a panel bar and behind the code it generates multiple panel bar ann each panel bar contains multiple items and all these panel bars are loaded dynamically???

I am trying to implement a ContextMenu for a treeview control (WPF) by using your Telerik's online tutorial. However, I often get error message as I copy & paste the tutorial code.

Here is what I have in XAML:
        <telerik:RadTreeView Canvas.Left="18" Canvas.Top="136" Height="615" Name="raceTreeView" Width="311" Background="Bisque" IsLineEnabled="True">
            <!-- This code segement implements a popup menu on the treeview.-->
            <telerik:RadContextMenu.ContextMenu>
                <telerik:RadContextMenu ItemClick="TreeContextMenu_ItemClick">
                    <telerik:RadMenuItem Header="Add" />
                    <telerik:RadMenuItem Header="Delete" />
                    <telerik:RadMenuItem Header="Edit" />
                </telerik:RadContextMenu>
            </telerik:RadContextMenu.ContextMenu>
        </telerik:RadTreeView>

Here is the relevant segements in C# code-behind:
using Telerik.Windows;
using Telerik.Windows.Controls;
using Telerik.Windows.Data;

....

private void TreeContextMenu_ItemClick(object sender, Telerik.Windows.RadRoutedEventArgs e)
   {
    MenuItem item = (e.OriginalSource as RadMenuItem).DataContext as MenuItem;
    switch ( item.Text )
    {
        case "Add":
            ....
        case "Edit":
            ....
        case "Delete":
            ....
        }
     }
   }

I get an error message on this line : switch ( item.Text )
'System.Windows.Controls.MenuItem' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Windows.Controls.MenuItem' could be found (are you missing a using directive or an assembly reference?)

How can I solve this problem?

Thanks,
Hamid

Please disregard this post. I found the error.

Hello.

I am new to Telerik. I need to populate a treeview with data from an Oracle DataReader (using ODP.NET which is an implementation of ADO.NET). Is there a step by step guide on this subject that I could use (XAML and C# code)?

Thanks,
Hamid
