Hello,

I need to be able to update a GridViewComboBoxColumn's ItemsSource when it drops down. How can I capture the drop down event of the GridViewComboBoxColumn? An example would be appreciated.

G

p.s. I am NOT using MVVM. I am binding the GridViewComboBoxColumn using ItemsSource of a List<int>.

Hi,

We are using the wpf RadRichText control in our project.
We have a grid control and one of the column is the rich text control and since we added the control we facing
a memory problems our application memory continue grow and it seems that the control don't free up memory.
here is the code:

Hello,

I have created a simple WPF app to demonstrate a bug we are seeing.

In our application, we have a RadPane that only certain users should be able to see because of Permissions.  We are attempting to do this using the Visibility property on the RadPane.

If I create a RadDocking control with a RadPaneGroup and set one of the RadPane elements Visibility property to Collapsed.  It does two things.

1. It shows up when I unpin the Visible RadPane (note that if you unpin the Service Card Explorer, you suddenly see the Operations Explorer)
2. If you try and repin the Pane, a Cannot call Arrange on a UIElement with infinite size or NaN. exception is thrown.

XAML



Steps to reproduce:

1. Launch the application
2. Unpin the 'Service Card Explorer' pane - note we suddenly see the Operations Explorer pane - this should not be
3. Unpin the 'Operations Explorer' pane
4. Try and pin the 'Service Card Explorer' pane - note the exception

Hey all, I am attempting to generate a heatmap from data I am pulling from a database. Basically, I am pulling a list of how many visitors we have had at our properties by customer zipcode. In the class I wrote to handle the data retrieval, I also have a method for Geocoding the zipcodes into Latitude and Longitude. The problem I am having is partly due to a poor understanding of WPF, and partly due to never having used a Telerik control before now. My current XAML is as follows:

I have seen the code samples from the telerik demos, but most likely due to my lack of experience with WPF they haven't helped me much. What I would like to be able to do would be for every zip code create a point on the map in a color representing the number of visitors, and upon mouse hover (or even mouse click) I would like to show a tooltip showing the number of visitors and the zipcode.

Would anyone know of a good tutorial to help fill in the gaps in my knowledge so I can more easily accomplish my goal, or have any input to send me in the right direction? Thanks for the help all!

Hey there,

can anybody explain how to show the state and city names on the map when using the EmptyProvider?

I am not using the openstreetmap or bingprovider because I only want to show Asia on my map centered on the screen.
If I am using one of the providers above the map shows basically the entire earth and not only the shapes I have binded (Asia).

I am looking for a map that only shows Asia centered in the screen with its capital city names and states.

Thanks for any feedback.

Below you'll find my xaml....

Hi,

I am having some problems with RadTreeView.ExpandItemByPath(...). It does not do anything when I call it.

I guess the problem is that  I did not set headers for the listviewitems, but when I try to set it with the commented setter, the name does not get displayed.

Below you can see the (stripped) XAML for my ListView:

Hi,

Could you please tell me what the best way to validating the form is? (and displaying error messages/highlighting fields)

Many thanks,
Daryl

Hi

I posted that as a support ticket, but if you have an answer for me, feel frre to give it, thank you very much. I'll paste the answer form the support.


 

I am testing your product. I am trying to make a nested hierarchy inside a radGridView. My code is inspired from both the Getting started documentation and an example you gave about nested hierarchy. Please, see the attached project.

 

My goal is to show a list of Divisions in a gridView, each division has teams, and each team has some employees.

 

I have an Employee class:

 

    public class Employee

    {

        public string FirstName

        {

            get;

            set;

        }

        public string LastName

        {

            get;

            set;

        }

        public int Age

        {

            get;

            set;

        }

        public bool Married

        {

            get;

            set;

        }

 

    }

 

 

A team class who has a collection of employees:

 

public class Team

    {

        private ObservableCollection<Employee> _empl = new ObservableCollection<Employee>();

 

        public ObservableCollection<Employee> Empl

        {

            get

            { return _empl; }

 

            set

            { _empl = value; }

        }

 

 

        public int Ident

        {

            get;

            set;

        }

        public string Nom

        {

            get;

            set;

        }

        public int Place

        {

            get;

            set;

        }

 

    }

 

 

A division class who has a list of teams:

    public class Division

    {

        public int Id

        {

            get;

            set;

        }

        public string Name

        {

            get;

            set;

        }

        public List<Team> Teams

        {

            get;

            set;

        }

 

    }

 

And a DivisionService class, who creates a collection of divisions, populating each division with some teams and some teams with some employees. Here is an excerpt of the class:

 

   public class DivisionsService

    {

        public static ObservableCollection<Division> GetDivisions()

        {

ObservableCollection<Division> divisions = new ObservableCollection<Division>();

            Division dA = new Division();

            dA.Name = "Division A";

            dA.Id = 1;

            dA.Teams = new List<Team>();

            Team team1 = new Team();

            team1.Ident = 1;

            team1.Nom = "Team I";

            team1.Place = 1;

            Employee emp01 = new Employee();

            emp01.FirstName = "Maria";

            emp01.LastName = "Anders";

            emp01.Married = true;

            emp01.Age = 24;

            team1.Empl.Add(emp01);

            Employee emp02 = new Employee();

            emp02.FirstName = "Klodia";

            emp02.LastName = "Choufleur";

            emp02.Married = false;

            emp02.Age = 28;

            team1.Empl.Add(emp02);

            dA.Teams.Add(team1);

 

            Team team2 = new Team();

            team2.Ident = 2;

            team2.Nom = "Team II";

            team2.Place = 2;

            Employee emp03 = new Employee();

            emp03.FirstName = "Jean";

            emp03.LastName = "Bon";

            emp03.Married = true;

            emp03.Age = 44;

            team2.Empl.Add(emp03);

 

            dA.Teams.Add(team2);

 

          (code here)

           

           return divisions;

        }

    }

 

 

The XAML creates the gridview and the data template:

 

<Window x:Class="TestRadGridView.MainWindow"

                           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"

                           Title="MainWindow" Height="350" Width="525">

             <Grid>

        <telerik:RadGridView x:Name="HierarchicalGridView"

                             AutoGenerateColumns="False"

                             MinHeight="386">

 

 

 

            <telerik:RadGridView.Columns>

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Id}"

                                       Header="Id" />

                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}"

                                       Header="Name" />

            </telerik:RadGridView.Columns>

 

            <telerik:RadGridView.HierarchyChildTemplate>

                <DataTemplate>

                    <telerik:RadGridView

                        Name="teamGrid"

                        ShowGroupPanel="False"

                        AutoGenerateColumns="False">

                        <telerik:RadGridView.Columns>

                            <telerik:GridViewDataColumn

                                Header="Id"

                                DataMemberBinding="{Binding Ident}"/>

                            <telerik:GridViewDataColumn

                                Header="Nom"

                                DataMemberBinding="{Binding Nom}"/>

                            <telerik:GridViewDataColumn

                                Header="Place"

                                DataMemberBinding="{Binding Place}"/>

                        </telerik:RadGridView.Columns>

                        <telerik:RadGridView.HierarchyChildTemplate>

                            <DataTemplate>

                                <telerik:RadGridView

                                    Name="employeesGrid"

                                    ShowGroupPanel="False">

                                </telerik:RadGridView>

                            </DataTemplate>

                        </telerik:RadGridView.HierarchyChildTemplate>

                    </telerik:RadGridView>

                </DataTemplate>

            </telerik:RadGridView.HierarchyChildTemplate>

 

        </telerik:RadGridView>    

    </Grid>

</Window>

 

 

And the code behind the data binding and the relations:

 

       public MainWindow()

        {

            InitializeComponent();

 

            GridViewTableDefinition TeamsTableDefinition = new GridViewTableDefinition();

            TeamsTableDefinition.Relation = new PropertyRelation("Teams");

            this.HierarchicalGridView.TableDefinition.ChildTableDefinitions.Add(TeamsTableDefinition);

 

            GridViewTableDefinition emplTableDefinition = new GridViewTableDefinition();

            emplTableDefinition.Relation = new PropertyRelation("empl");

            TeamsTableDefinition.ChildTableDefinitions.Add(emplTableDefinition);

 

 

            this.HierarchicalGridView.ItemsSource = DivisionsService.GetDivisions();

 

        }

 

 

So, it does not work: I see the divisions, but there are no teams (and of course I can’t see is there are employees in the teams).

 

If I delete, in the XAML code, the data template, things are a little better: I see Teams in the divisions, but I do not see Employees in teams. Anyway, I need the data template.

 

So, what I did wrong?

 

 

Could-you too, please, say how to access a selected item in a nested grid? Thank you again.

 

Cordially

Hi, I am prototyping with radgridview and am not very wpf experienced. I have a simple problem I can't solve and am hoping someone can give me a hint.


"data" is an ObservableCollection and I was expecting the grid to update, when the collection gets updated. Data already in the list after initialisation is shown. I guessed this does not work, as its a StaticResource, but with DynamicResource it also does not work.

However if i use c# code it works:


Now its obvious to me I am doing something wrong with the ItemsSource in xaml, but I just have no clue what I should be doing...

Hi, How can I add the item template i create from the ResourceTypeTemplateSelector? 

All I wanted is that when  i click on a certain tab, a radgrid will appear. thanks
