Help with CheckBox Template

I am using the DataTemplate in the GirdViewDataColumn.CellTemplate as follows.

<telerik:GridViewDataColumn DataMemberBinding="{Binding Others}" ColumnGroupName="ATTRIBUTES">
<telerik:GridViewDataColumn.CellTemplate>
<DataTemplate>
<CheckBox Content="{Binding Path=Others}" IsChecked="{Binding Path=IsSelected,Mode=TwoWay}" Height="16" HorizontalAlignment="Left" Margin="2" VerticalAlignment="Top" />
</DataTemplate>
</telerik:GridViewDataColumn.CellTemplate>
</telerik:GridViewDataColumn>

I want the check box to appear only when I have data in that cell. How would I achieve this? Right now, I am getting just the CheckBox in the cells where there is no data to display.

I am attaching the screen shot of the current behavior. Any help is greatly appreciated.

CheckBox in GridView.DataColumn.CellTemplate

Hello I was wondering if there is a way to make the checkbox that appears in the respective columns "un-checkable" , essentially read only. I say that because when I set the column to be read only the user is still able to check the checkbox. Even if I set the whole RadGridView

<telerik:GridViewDataColumn Width="40" IsReadOnly="True">

<telerik:GridViewDataColumn.Header>

<StackPanel>

<TextBlock Text="Lab"></TextBlock>

<TextBlock Text="Req"></TextBlock>

</StackPanel>

</telerik:GridViewDataColumn.Header>

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<CheckBox HorizontalAlignment="Left" VerticalAlignment="Center" IsChecked="{Binding LabRequired}"

/>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

<telerik:GridViewDataColumn.CellStyle>

<Style TargetType="telerik:GridViewCell">

<Setter Property="Background" Value="{Binding LabStatus, Converter={StaticResource MyConverter}}" />

</Style>

</telerik:GridViewDataColumn.CellStyle>

</telerik:GridViewDataColumn>

to read only along with the individual columns it still is able to be clicked.

IsSynchronizedWithCurrentItem property is missing in GridViewComboBoxColumn

Hi,

Consider adding IsSynchronizedWithCurrentItem to GridViewComboBoxColumn. As of now I am using this to work around the issue:

</Style>

The problem is that I bind the GridViewComboBoxColumn to a StaticResource of type CollectionViewSource and by default (in the latest release) you have IsSynchronizedWithCurrentItem set to true this will make all my columns show the same item.

Let me know if you need a demo for this.

Regards,

GridView

Customize Date Field in Custom Editor

If an attribute is of type DateTime, the default control on the right side is a Date Picker, however when I try to get the filtered expression, I get in this format: '8/21/2012 11:10:00 PM'

Is there a way we can customize this in the following (or any other format?): 21-AUG-2012 (I also don't need the time attribute)

Please let me know.

Cannot make PieChart take up 100% of parents space

Hello,

I am exploring the PieChart and, like som many others, I've stumbled across problems with its size. As I understand it the PieChart should take up 100% of its parent's area but so far it is always rendered at some sort of minimum size and I need help understanding why. The only difference between my XAML and the ones I've seen in your vanilla examples is the fact I render using DataTemplates, as a result of using MVVM.

This is the XAML I use to try it out:

<DataTemplate x:Key="PieChartTemplate">

<Grid Background="Beige">

<telerik:RadPieChart VerticalAlignment="Center" HorizontalAlignment="Center" Background="CadetBlue" >

<telerik:PieSeries ShowLabels="True">

<telerik:PieSeries.DataPoints>

<telerik:PieDataPoint Value="10" Label="A"/>

<telerik:PieDataPoint Value="4" Label="B"/>

<telerik:PieDataPoint Value="7" Label="C"/>

<telerik:PieDataPoint Value="11" Label="D"/>

<telerik:PieDataPoint Value="15" Label="E"/>

</telerik:PieSeries.DataPoints>

</telerik:PieSeries>

</telerik:RadPieChart>

</Grid>

</DataTemplate>

And here's how it renders:

http://www.flickr.com/photos/59656722@N06/7830046920/in/photostream/lightbox/

Please note that the PieChart's parent is the beige grid. I also set a background color ("CadetBlue") for the PieChart itself to see how much space it uses.

Please help me understand how to fix this.
Thanks

How to set a column like a ComboBox into a RadGridView through code-behind

Hi

I have seen some examples of how to set up a column of type combo but they all include functionality and other code on the page.

I set a combobox type column given a dataset that comes from a database query, but all through code behind.

I require that the XAML does not hold beyond labels and minimum properties and necessary for a creation of RadGridView.

Is this possible?
Could you provide me an example or direction where to inquire?

Language: VB.NET
Platform: WPF Web.

thanks

ensure visible and select node

Hello,

I am building a tree programmatically. After adding all of the items i would like to select one of them and to scroll to it (ensure that it is visible). i am using the node object (RadTreeViewItem) to set the IsSelected property to true, and then use the EnsureVisible method. The node is indeed selected. However any methods that are registered to the Selected event are not invoked. In addition, the item stays invisible and manual scrolling is required.

Any ideas?

thanks,

Liat.
