Is it possible to draw in the charting area? For example, I would like to draw a red line, perhaps, through the chart at the Y-Value of 60 (assuming this chart has one Y-Axis). Or perhaps I would like to shade the area above the Y-Value of 100 red. I know I can do the shading by setting the background brush, but its critical to know where the Y-Value of 60 or 100 is in these examples. Is this possible with RadChart?

Hi,

Hi All

I have tried all manor of solutions to this problem.

Basically I have an attributes table which contains a type. this type is bound to a GridViewComboBoxColumn. when the selection in this column is changed, it needs to set the isvisible value of other columns in the same grid row.

So, in the usual way, I have created a converter such as this:

in the xaml, the converter is called like this:

The value for the cell is updated when the attribute_id is changed, but the visibility converter is never called.


the second option that I have tried is to use the GridViewdataColumn element, such as this:

gridAttributes_attributeType1 is the name of the GridViewComboBoxColumn.

This also does not call the converter as I suspect that the path SelectedValue does not exist in a GridViewComboBoxColumn.

The solution does call the converter however, if I bind it to a combo outside of the gridview..

Is there any solution to this problem.

Hi,
i want to use checkboxes in several columns and therefore my code - for 1 gridview column - looks like this:
____________________________________________________________________

<telerik:GridViewDataColumn x:Name="colResultNT" Header="Result NT" IsReadOnly="True" IsEnabled="False" DataMemberBinding="{Binding ResultNt}">
                                </telerik:GridViewDataColumn>
                                <telerik:GridViewDataColumn x:Name="colReview" Header="Review Needed?" DataMemberBinding="{Binding IsReviewNeeded}">
                                    <telerik:GridViewDataColumn.CellStyle>
                                        <Style TargetType="GridView:GridViewCell">
                                            <Setter Property="Template">
                                                <Setter.Value>
                                                    <ControlTemplate TargetType="GridView:GridViewCell">
                                                        <CheckBox Margin="5,0,0,0"
                                                                HorizontalAlignment="Left"
                                                                VerticalAlignment="Center"
                                                                IsChecked="{Binding IsReviewNeeded, Mode=TwoWay}" />
                                                    </ControlTemplate>
                                                </Setter.Value>
                                            </Setter>
                                        </Style>
                                    </telerik:GridViewDataColumn.CellStyle>                                    
                                </telerik:GridViewDataColumn>  
____________________________________________________________________
This code works fine, but actually the vertical grid line on the right sight disappered (see attached screenshot). Any ideas why? How can i get it back?
Thx in advance
                            
                              

Hello,

I have a difficulty about binding a list of type Binding<T> list to Grid. The binding is working fine, but grouping is not working on the side of XAML.

grouping via code works fine, XAML is not working.

Am I doing something wrong ?

Telerik Version : 2010.1.0422.35

Please help...

I'm thinking of a hybrid control that would allow the user to select a year, a month in a year a date, or collection of dates.

I just downloaded and installed the latest WPF trial version. The demo solution file appears to be in VS 2010 format. Is there and where can I download the VS 2008 Solution file for the latest demo?

Good morning,
 I would like to use the transition control to avoid building a storyboard.

My Code is :

private

 

 

void btnDisplay_Click(object sender, RoutedEventArgs e)

 

{

 

 

try

 

{

 

 

for (int i = 1; i < 9; i++)

 

{

 

 

Image myImg = new Image();

 

myImg.Source =

 

new BitmapImage(new Uri("C:\\00002512\\00000000" + i.ToString() + ".TIF", UriKind.Absolute));

 

 

 

this.TransitionControl1.Content = myImg;

 

 

 

this.radProgressBar1.Value = i;

 

 

}

}

 

 

catch (Exception ex)

 

{

 

 

MessageBox.Show(ex.Message);

 

}

}

I get this error : "Cannot perform action because the specified Storyboard was not applied to this object for interactive control." when I try to load the second image.

Can you help me?

thanks in advance

Hi,

I'm trying to have custom TabItems in a RadGroupPane in DocumentsHost. As I'm understand RadGroupPane items are rendered using TabItemPresenter (looked at RadGroupPane template) and are RadTabItem controls. Problem is that I can not get them to style.
A litle sample or idea how to set custom template for TabItem's in a RadGroupPane would be really good, as setting it in RadGroupPane resources as style with TargetType for RadTabItem seems don't work.

Thanks,
Saulius

Hello,

I have a RadGridView with a custom row style targeting GridViewRow (set using RowStyle property and defined in resource dictionary).
In that style I have a control template targeting GridViewRow.
In that template I have a couple of GridViewCells definitions.
Here is one of them, for example:



Now, what I am trying to accomplish is to bind the Visibility property to the column IsVisible property (using the required converter).
The problem is that both Column and DataColumn properties of the GridViewCell are unknown at run time (saw it using Snoop).

How do I make my GridViewCell hide when the matching column is hidden?

Thanks,
Gili
