Hello All,

RadComboBox has a property called "EmptyText" which displays when the combo box has not been set (meaning SelectedIndex = -1).  Is there similar functionality in the RadGridView that is *already baked in*?  When a user changes the filter and the grid has not rows to display, I want to display a message in the body of the grid like "No rows to display".

Hi,

Please could you inform me why I cannot set an ItemContainerStyle for a RadBreadcrumbItem. I thought that I may be able to use a style to set a default image, with the following XAML...

<telerik:RadBreadcrumb.ItemContainerStyle>
                <Style TargetType="{x:Type telerik:RadBreadcrumbItem}">
                    <Setter Property="Image" Value="{StaticResource Folder16}"/>
                </Style>
            </telerik:RadBreadcrumb.ItemContainerStyle>

However, I get the following error at runtime....

{"'RadBreadcrumbItem' type must derive from FrameworkElement or FrameworkContentElement."}

Thanks

Hi,

After upgrading to RadControls for WPF 2012.2.607, the Demos app crashes on launch with the following error:

"WPF Demos has stopped working".

I have a form with a couple of RadGridView controls on it.  The form in question is a UserControl, embedded in a TabItem in a TabControl on the MainWindow.  There is another UserConrol on another TabItem in the same TabControl, which is used to display details of the selected item in one of the RadGridView controls, and other that is used to display the details of the selected item in the other RadGridView.

Here is the Xaml for one of the RadGridView controls:

From the code-behind, here is the code for the SelectionChanged event handler and for the MouseDoubleClick event handler:

Everything works, but there's something very odd going on.  When you double click on the row, the RadGridView seems to scroll.  In fact, it scrolls far enough to bring the row you just double clicked on off the screen. Note that the call to ScrollIndexIntoView has no effect:  I added that to try to bring the row back into view and it's doing nothing.

In the UserControl in the other tab, there are two buttons named "PrevButton" and "NextButton".  Here is the code for their Click event handlers:

And here's the NextRecord and PrevRecord methods in the SearchControl:


Again, everything works, but the ScrollIntoView doesn't work.  I've always had that call there, in case you kept clicking one of the buttons and eventually selected a row that wasn't in view.

All rows are the same height, and turning RowVirtualization off has no effect.  The rows are still off the screen when I come back to the tab with the RadGridViews.

Is this a bug? Is there some property I have turned on that's breaking it?

P.S.  I am using version 2012.1.326.40

I'm evaluating RadGridView (WPF) with an OData service. Version 2012.2.607.40
Seeing some very strange behavior with a simple application.

My service schema exposes:

ResourceSetA (1 item)
ResourceSetB (3 items)
ResourceSetC (6713 items)

I'm monitoring calls to the service with Fiddler2.

I have a simple test app with a RadGridView in a Window by itself, its ItemsSource bound to a DataServiceQuery<T> property from my service client proxy.

When T=ResourceA, the service calls are essentially:

/Service.svc/ResourceSetA()/$count
/Service.svc/ResourceSetA()?$skip=0&$top=1

and the grid displays the single item correctly.

When T=ResourceB, the service calls are:

/Service.svc/ResourceSetB()/$count
/Service.svc/ResourceSetB()?$skip=0&$top=3

and the grid displays three items correctly.

When T=ResourceC, I only see a single call, which appears to return the correct count according to Fiddler (6713):

/Service.svc/ResourceSetC()/$count

but my client application hangs and makes no further OData calls. Watching the process in Task Manager, it eats memory steadily and eventually falls over with an OutOfMemoryException.

My app is really the simplest example I can craft, and my service is responding correctly when I issue calls to it directly from a browser.
What could I be doing wrong here? 

Hi,

in my project I use the OfficeBlue Telerik theme. I want to customize my StatusBar base on my Telerik theme.

Actually I have CustomStyles.xaml and I want to use some Telerik resource keys instead of their corresponding
value but I don't know to do it, here is my XAML file:

<ResourceDictionary
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
  
    <Style TargetType="StatusBar">       
        <Setter Property="StatusBar.BorderThickness" Value="1" />
        <Setter Property="StatusBar.Background">
            <Setter.Value>               
                <SolidColorBrush Color="#FFE2F0FD" /> <!--Telerik: Key="ControlBackground_Disabled"-->
            </Setter.Value>
        </Setter>
       
        <Setter Property="StatusBar.BorderBrush">
            <Setter.Value>
                <SolidColorBrush Color="#FF9BB0CD" /> <!--Telerik: Key="ControlOuterBorder_Disabled"-->               
            </Setter.Value>
        </Setter>       
    </Style>

</ResourceDictionary>

Hi!
I have a RadGridview where i have few columns and based on this column  i have to sort only those columns whose length is greater than 4 if the rows have string with length less than 4 those should not be visible.

I tried using CompositeFilterDescriptor but it does not filter for string with length less than 4.
I tried the following code.

                This Code works fine:
              CompositeFilterDescriptor FilterAnd = new CompositeFilterDescriptor();
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustName", FilterOperator.IsNotEqualTo, ""));
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustName", FilterOperator.IsNotEqualTo, null));
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustAddress", FilterOperator.IsNotEqualTo, ""));
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustAddress", FilterOperator.IsNotEqualTo, null));
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustCity", FilterOperator.IsNotEqualTo, ""));
                FilterAnd.FilterDescriptors.Add(new FilterDescriptor("CustCity", FilterOperator.IsNotEqualTo, null));
                FilterAnd.LogicalOperator = FilterCompositionLogicalOperator.And;

                This code is not working:
                CompositeFilterDescriptor FilterOr = new CompositeFilterDescriptor();
                FilterOr.FilterDescriptors.Add(new FilterDescriptor("CustName", FilterOperator.IsGreaterThan, 4));
                FilterOr.FilterDescriptors.Add(new FilterDescriptor("CustAddress", FilterOperator.IsGreaterThan, 4));
                FilterOr.FilterDescriptors.Add(new FilterDescriptor("CustCity", FilterOperator.IsGreaterThan, 4));
                FilterOr.LogicalOperator = FilterCompositionLogicalOperator.Or;

                grid.FilterDescriptors.Add(FilterAnd);
                grid.FilterDescriptors.Add(FilterOr);

How can i use IsGreaterThan with string length can any one help me?

Hi,

I'm trying to use a radfilter that filters the items in my radgridview, based on textinput in a textbox

this is my code : 



but I get the following exception : 


depending on user selection, the control gets loaded and unloaded several times (datatemplate selector).

The code-line giving the exception is mFilter.FilterDescriptors.Add(birthDateFilter);
Surrounding this statement with a try-catch block solves the problem.
The filter continues to work, although an exception is thrown multiple times (every time the textchanged event is triggered) 

Hi,

when I search for a certain uncontained text in PdfViewer your prompt a messagbox which says that the text cannot be found. How can i localize this message?

Best Regards

Hello Telerik,

I'm trying to bind a ChartDataSource control to a dictionary, then draw a LineSeries. 

Previously, I made extensions classes to the DataPointBinding class for binding to the dictionary, no problem! Problem is that the ChartDataSource never gets populated. It stays empty even after adding a new item to the dictionary and re-setting the chartdatasource.itemsource=dictionary.

I am adding the chartdatasource to the window with the radcartesianchart prior to adding the series to the graph.

Could I have an example of how to set the Category/Value Binding for a ChartDataSource in codebehind please?
