Custom Presentation: Highlight Text Not Contained Within Annotations

Hi,

I haven't attempted this yet but, do you have any advice on the best way to highlight any text that is NOT contained within Custom Annotations?

i.e. what do you think is the most efficient check process to find and highlight all text not contained within annotations?

Thanks for your time, any advice is appreciated,

How to Find controls in RadGridView once code behind class contructor executed InitializeComponent() method executed

How Find Child controls in RadGridView once code behind class contructor executed InitializeComponent() method.

When I wanted to find Child controls in the RadGridView it returns null. I came to know that once I click on any button then I can find the child controls of the RadGridView but my requirement is find child controls after InitializeComponent() method executed and update their values as per business rules.

Please help me

How to change formatting on specific cells

So I have a dynamic RadGridView using MVVM and Caliburn Micro. This means that I add Columns programmatically to the control. basically like this:

for (int i = 0; i < length; i++)
{
    Binding b = new Binding(string.Format("Collection[{0}].ValueIWant", i));
    binding.StringFormat = "{0:0.##}";
    GridViewDataColumn column = new GridViewDataColumn()
    {
        Header = HeaderFor(i),
        DataMemberBinding = b,
        DataType = typeof(double?)
    };

    Control.columns.Add(column);
}

Now I need to add new lines that show the percentage between line 1 and 2, 2 and 3 and so on.

I've managed to do that but I'm not sure how I would manage to change the String.format specifically for those cells instead of the whole column.

CellTemplateSelector came to mind but I'm not sure that is a good idea as this might mean I have to set the binding again, not knowing the value of i and such. Also I only want to change the string.format on the binding.

As I'm manipulating the number as a double (0,5 is 50%, 50 is 5000%) I guess I have to mask the input as well. not sure if String.Format does that for me as well or if I should use RadMaskedInput

RadContextMenu Items Icon not visible with dynamic binding

I am having a problem displaying the context menu RadContextMenu with Icon, I am using dynamic binding to observable collection, which contains context menu items (Text and Icon), I am following this tutorial "Dynamic Binding", following is my XAML.

<Style x:Key="MenuItemStyle" TargetType="{x:Type telerik:RadMenuItem}">

<Setter Property="Icon">

<Setter.Value>

<Image Source="{Binding IconPath, Converter={StaticResource pathtoimage}}" />

</Setter.Value>

</Setter>

</Style>

<HierarchicalDataTemplate x:Key="MenuItemTemplate">

<telerik:RadButton Content="{Binding Title}" HorizontalContentAlignment="Left" Background="Transparent" BorderBrush="Transparent" />

</HierarchicalDataTemplate>

and following is the XAML of RadGridView, on which context menu is placed.

<telerik:RadGridView x:Name="myGridView" AutoGenerateColumns="False" ItemsSource="{Binding GridData}" VerticalAlignment="Top">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Result}" Header="Result"/>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Category}" Header="Category"/>

</telerik:RadGridView.Columns>

<telerik:RadContextMenu.ContextMenu>

<telerik:RadContextMenu ItemsSource="{Binding ContextMenuItems}" ItemContainerStyle="{StaticResource MenuItemStyle}" ItemTemplate="{StaticResource MenuItemTemplate}">

</telerik:RadContextMenu>

View Model is as follows

class MainViewModel

{

private ObservableCollection<MenuItemObj> menuitems_;

public ObservableCollection<MenuItemObj> ContextMenuItems

{

get

{

return menuitems_;

}

set

{

menuitems_ = value;

}

private ObservableCollection<GridRowDataObj> griddata_;

public ObservableCollection<GridRowDataObj> GridData

{

get

{

return griddata_;

}

set

{

griddata_ = value;

}

public class MenuItemObj

{

public string Title { get; set; }

public string IconPath { get; set; }

}

public class GridRowDataObj

{

public string Result { set; get; }

public string Category { set; get; }

}

and setting DataContext as

//TODO

ObservableCollection<GridRowDataObj> gd = new ObservableCollection<GridRowDataObj>();

gd.Add(new GridRowDataObj() { Result = "Matric", Category = "SSC" });

gd.Add(new GridRowDataObj() { Result = "FSc", Category = "HSSC" });

gd.Add(new GridRowDataObj() { Result = "FA", Category = "HSSC" });

//TODO

ObservableCollection<MenuItemObj> mi = new ObservableCollection<MenuItemObj>();

mi.Add(new MenuItemObj() { Title = "My Item 1", IconPath = "/Images/item1.png" });

mi.Add(new MenuItemObj() { Title = "My Item 2", IconPath = "/Images/item2.png" });

mi.Add(new MenuItemObj() { Title = "My Item 3", IconPath = "/Images/item3.png" });

MainViewModel mvm = new MainViewModel();

mvm.ContextMenuItems = mi;

mvm.GridData = gd;

this.DataContext = mvm;

What I am getting is like this as in attached file "Menu_Image.png"

I am not sure why the icons for first and second menu items are not displayed, I have checked that the icon is displayed for last menu item only. I have complete project replicating this scenario, I can send you if required, Please help me out?

Rad Control Assembly Protection

Hi,

We wanted to implement Rad Control Assembly protection in our WPF application we are developing.

Following the documentation as per the below link

http://www.telerik.com/help/wpf/protecting-telerik-radcontrols-assembly.html

Where can I find the Source code for Rad Controls (WPF) with BUILD instructions.

We are currently using 2012 Q1 release and having plans to upgrade.

Could you kindly provide the Source Code with BUILD instructions for Rad Control Assembly protection or provide me with the resources / Iinks I can refer to and download.

Kindly suggest.

Thank you & Regards,

Phani.

Place RadTreeView inside the root PanelBarItem

Can we use RadTreeView in a root item?

Ex:
---------------------------------------
RootNode1 ( RadPanelBarItem.Header ) <-- Root Item 1
---------------------------------------
+ Level1 (RadTreeView)
|---- Level2
.......
---------------------------------------
RootNode2 ( RadPanelBarItem.Header ) <-- Root Item 2
---------------------------------------
+ Level1 (RadTreeView)
|---- Level2
.......

BTW: We are using MVVM, the hierarchical data updates dynamically.

Thanks.

Is possible to hide parent node?

If the data like below:

RootNode1
- Level1
-- Level2
--- Level3

and I would like to provide a check box to hide Level1 or Level2
Ex: Hide Level1 the output should be

RootNode1
- Level2
-- Level3

Ex: Hide Level2 the output should be

RootNode1
- Level1
-- Level3

Ex: Hide both Level1 and Level2 the output should be

RootNode1
- Level3

Is possible to do it with RadTreeView?

BTW: we are using RadControl for WPF 2012.2.0725, and the each level in the tree is an ObservableCollection list, and we use converter to convert each list into ListCollectionView to handle sorting and filtering ( http://www.zagstudio.com/blog/434#.UDz-sNaPXng ).

Thanks.

  <Setter Property="FontSize" Value="26"/>         
 </Style>    
</Window.Resources> 
<telerik:RadPaneGroup  Style="{StaticResource headerStyle}">                     
 <telerik:RadPane x:Name="_outputControl" CanUserClose="True" Header="Output" >
