Options in DataFormComboBoxField

[Alan]

Hello,

I am trying to implement a RadDataForm using a DatFormComboBoxField. Following this section of documentation: http://docs.telerik.com/devtools/wpf/controls/raddataform/how-to/raddatafor-edit-lookup-values-with-radcombobox

I have been unable to produce results. 

I stumbled across the ability to use an enum within a class to allow all of the enum's values to be combo box items. Sadly, as our combobox options will be changing based on our database, this won't be an effective solution. Are there any similar methods to add options to a combo box (dictionary, json object, etc)?

This has been a struggle for a few days now, any help is greatly appreciated...

Hello Alan,

I have prepared a sample project, demonstrating how you can set up a DatFormComboBoxField and also update its ItemsSource during runtime. Could you please have a look at it and let me know whether such an approach would be applicable in your scenario? 

If that is not the case please provide more information on the exact setup at your end so that I may better assist you in finding a solution to your issue. Specifying the class structure at hand would definitely be of help.

I will be awaiting your reply.

Dilyan,

Thanks for the response. I believe the section that keeps messing me up is the RadDataForm_AutoGeneratingField.

I followed another tutorial on this as well and its use keeps eluding me, as i am new with wpf and C#.  I'm not quite sure what falls into the paths or propertynames. My Class that the form is based on is:

 

using MongoDB.Bson;
using System;
using System.Collections.Generic;
using MongoDB.Driver;
using MongoDB.Bson.Serialization;
using Newtonsoft.Json;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.IO;
using System.Net;
using System.Text;

            ***Other DB and Http Request Calls***


        
        
        public event PropertyChangedEventHandler PropertyChanged;

        private void NotifyPropertyChanged(string info)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(info));
        }
    }
}

 

The combo class is just an int to link to a string of a service rep's name.

 

Any help is greatly appreciated

Hello Alan,

From what I understood from your previous reply, you're not autogenerating RadDataForm's fields but defining data templates for the ReadOnlyTemplate and EditTemplate properties, am I correct?

If that is the case, here's the code from my previous reply, translated into XAML:

<DataTemplate x:Key="MyTemplate">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <telerik:DataFormDataField Label="Name" DataMemberBinding="{Binding Name, Mode=TwoWay}" />
        <telerik:DataFormComboBoxField Grid.Row="1"
                                       Label="Country"
                                       DataMemberBinding="{Binding CountryID, Mode=TwoWay}"
                                       ItemsSource="{Binding Countries, Source={StaticResource MyViewModel}}"
                                       SelectedValuePath="ID"
                                       DisplayMemberPath="Name"/>
    </Grid>
</DataTemplate>

<telerik:RadDataForm x:Name="radDataForm" AutoGenerateFields="False" ReadOnlyTemplate="{StaticResource MyTemplate}" EditTemplate="{StaticResource MyTemplate}" CurrentItem="{Binding Clubs[0]}" />

For your convenience, I'm also attaching the modified version of the project. Of course, you will need to adjust this to work with the setup you have at your end.

Do let me know how this goes.
