Data Virtualization on grid with WCF Service

Hi,

I have a wcf service which return me list of items.

I wanted to use this service as Data Virtualization in wpf example.

For ex

I wanted to show 50 customers in the grid and when user scolls down to grid end, grid should be populated with next 50 customers.

I don't want to use WCF RIA/Data services, I have already existing wcf service which gives me list.

Please help me to achieve this.

[Solved] Customizing RadAutoCompleteBox

Hi,

I am trying to customize the RadAutoCompleteBox visual to fit our application. I went thru the process of doing "Edit a Copy" of the Style. Without making any modification to the copied style, I've encountered an Error which causes the popup no longer shows up correctly.

System.Windows.Data Error: 26 : ItemTemplate and ItemTemplateSelector are ignored for items already of the ItemsControl's container type; Type='RadWatermarkTextBox'
System.Windows.Data Error: 4 : Cannot find source for binding with reference 'ElementName=WatermarkTextBox'. BindingExpression:Path=ActualWidth; DataItem=null; target element is 'AutoCompleteBoxesWrapPanel' (Name=''); target property is 'Width' (type 'Double')

[Solved] Increase size of GridView Filter values

Hi,

In my GridView, i used a filter. In this filter, there is a lot of values, but not all of them :

We can see on screen '1' that the maximum value is '1.334', but on my graphic, the top of my curve is superior to 5.

BUT

When i choosed "superior to 5" in this same filter (screen '2'), I can see my values on my grid.

I want to know how I can see all of values in the values list ?

Thank you very much.

Valentin.

[Solved] GrdiViewDataColumn with converter and converterparameter with binding

<telerik:GridViewDataColumn Header="Valore" DataMemberBinding="{Binding Value,Converter={StaticResource DynamicsParameterConverter}}" />

Actually I have this column, my entity has other property called "Type", this one show me how to use a converter class.

I would change this column in this vesion

<telerik:GridViewDataColumn Header="Valore" DataMemberBinding="{Binding Value,Converter={StaticResource DynamicsParameterConverter}, ConverterParameter={Binding Type}}" Width="*" />

But I can't do this because ConverterParameter is not compatible with DependencyProperty, is there a workaround or feature of column for this?

[Solved] Telerik WPF controls doesnt show up on sample project

Hi,

We have a existing WPF-MVVM project in which if I add any telerik controls, it is reflecting in the screen when I run the application.

But with the same telerik dlls, if I am trying to create a new sample project on one of the controls(ex:RadWindow) I am not able see any controls when I run the application. It just appears blank.

I am not sure what I am missing. Is it mandatory to add Theme resources to the project? or is it something else? Please help me on the same.

Thanks,

Santhosh

Expression Blend throughs exception: Can only base on a Style with target type that is base type 'RadPaneGroup'.

Hi,

I'm adding Docking to my app with the following structure (all unnecessary properties removed):

<telerik:RadDocking >
<telerik:RadDocking.DocumentHost>
<Grid/>
</telerik:RadDocking.DocumentHost>

<telerik:RadSplitContainer Orientation="Horizontal" InitialPosition="DockedBottom">
<telerik:RadPaneGroup>
<telerik:RadPane>
<Grid/>
</telerik:RadPane>
</telerik:RadPaneGroup>
</telerik:RadSplitContainer>
</telerik:RadDocking>

When I'm creating styles for RadPane and RadPaneGroup, I'm constantly getting exceptions in Design view of Expression Blend and Visual studio that looks like:
"InvalidOperationException: Can only base on a Style with target type that is base type 'RadPaneGroup'."

As a result, I can't see my control in Design View and can't edit control's property in Properties pane visually. The style is looking like this:

<Style TargetType="telerik:RadPaneGroup" BasedOn="{StaticResource RadPaneGroupStyle}">
...
</Style>

What's wrong?
Thank you!
