Hi,

I'm looking for a way to bind a List of key / value objects to the propertygrid. Consider the following snippets of code:

public void PopulatePropertyGrid()
{
    List<MyKeyValueClass> propertyList = new List<MyKeyValueClass>();
    propertyList.Add(new MyKeyValueClass(){ Key="property1", Value="value1" });
    propertyList.Add(new MyKeyValueClass(){ Key="property2", Value="value2" });
    propertyList.Add(new MyKeyValueClass(){ Key="property3", Value="value3" });
    //How do I bind this List to a RadPropertyGrid, so I get 3 properties with filled in values?
}


public class MyKeyValueClass
{
    public string Key {get;set;}
    public string Value {get;set;}
}



I tried something like this:
XAML:
<telerik:RadPropertyGrid x:Name="radPropertyGrid" AutoGeneratePropertyDefinitions="false" />


.cs:
radPropertyGrid.PropertyDefinitions.Clear();
foreach (MyKeyValueClass mkvc in propertyList)
{
    radPropertyGrid.PropertyDefinitions.Add(new PropertyDefinition()
    {
        DisplayName = mkvc.Key,
        Binding = new Binding("Value")
    });
}
radPropertyGrid.Item = propertyList;




This sets the displaynames accordingly, but won't show / bind the values 
Is this possible?

Stan

Hello Illya,

I have tested the code snippets with our current official release - Q1 2014 SP and it seems that it works correctly. Can you try testing your application with that version ? Do you have any problems with it ?

Dear Admin,

I am still facing this problem. I am looking for binding list of key value to the property grid.Please check the code snippet

//Expectation SET
  public class ExpectationSet
    {
        public string Name { get; set; }
 
        public  List<ExpectationProperty> ExpectationProperties { get; set; }
         
 
        public static List<ExpectationSet> AvailableSets
        {
            get
            {
                return new[]{
                    new ExpectationSet
                    {
                        Name ="se1",
                        ExpectationProperties =new[]
                        {
                            new ExpectationProperty{Name="se1.x",Value="se1x"},
                            new ExpectationProperty{Name="se1.z",Value="se1z"}
                        }.ToList()
                    } ,
                     new ExpectationSet
                    {
                        Name ="se2",
                        ExpectationProperties =new[]
                        {
                            new ExpectationProperty{Name="se2.x",Value="se2x"},
                            new ExpectationProperty{Name="se2.z",Value="se2z"},
                            new ExpectationProperty{Name="se2.y",Value="se2y"}
                        }.ToList()
                    },
                     new ExpectationSet
                    {
                        Name ="se3",
                        ExpectationProperties =new[]
                        {
                            new ExpectationProperty{Name="se3.p",Value="se3p"},
                            new ExpectationProperty{Name="se3.q",Value="se3q"},
                            new ExpectationProperty{Name="se3.r",Value="se3r"}
                        }.ToList()
                    }
                }.ToList();
            }
        }
 
      
 
        
    }
//ExpectationSet Properties
public class ExpectationProperty
    {
        public string Name { get; set; }
        public string Value { get; set; }
    }
// Code snippet to bind propertygrid
foreach (ExpectationProperty mkvc in ExpectationSet.AvailableSets[i].ExpectationProperties)
{
String value = mkvc.Value;
PropertyGrid1.PropertyDefinitions.Add(new PropertyDefinition()
{Binding = new System.Windows.Data.Binding("Value"),
DisplayName = mkvc.Name
});
PropertyGrid1.Item = mkvc;
}
//xaml File
<telerik:RadPropertyGrid x:Name="PropertyGrid1"  Grid.Row="2" Grid.RowSpan="2"
                                                        
                AutoGeneratePropertyDefinitions="false"
                                       
                                   />

Hello Payal,

DataContext of the each property definition is the object property grid is bound to. So, if you want to bind to a property of the item belonging to a property definition, you need to specify the source. For example:

var mkvc = ExpectationSet.AvailableSets[1].ExpectationProperties;
 
            foreach (ExpectationProperty item in mkvc)
            {
                String value = item.Value;
                PropertyGrid1.PropertyDefinitions.Add(new PropertyDefinition()
                {
                    Binding = new System.Windows.Data.Binding("Value") { Source = item },
                    DisplayName = item.Name
                });        
            }
 
            PropertyGrid1.Item = mkvc;

I am trying to show list of key/value to radpropertygrid. Consider the following snippet of :

                                   foreach (var propValue in instance)
                                {   
                                    if(propValue.StringValue != null)
                                    {

                                        string value = propValue.StringValue;     
                                        rad_property_grid_1.PropertyDefinitions.Add(new PropertyDefinition()
                                        { 
                                            Binding  = new System.Windows.Data.Binding("value") ,                                            
                                            DisplayName = propValue.Property.DisplayLabel //Property.DisplayLabel
                                        });
                                         
                                    }                                                                                                         
                                }

Hello Maya,

i am looking to bind key-values to my radpropetrygrid. Consider following code:

     foreach (var data in properties)
                                {
                                    if (data.Value != null)
                                    {                                      
                                        var value = data.Value;

                                        radPropertGrid1.PropertyDefinitions.Add(new PropertyDefinition()
                                        {
                                            Binding = new System.Windows.Data.Binding(value),
                                            DisplayName = data.key
                                        });
                                    }

Hello Shweta and Shivkanya,

While I am not aware of the exact setup on your side, I have prepared a sample project which demonstrates how you can bind key-values to RadPropertyGrid based on the earlier discussion in the thread. May I ask you to check it out and see how it differs from the setup at your end?

Should you need any further assistance, may I ask you to open a new support ticket/forum thread and provide some additional information about your exact setup and potentially a sample project demonstrating the difficulties that you have encountered?

Hello Shweta,

Thank you for the attached picture.

You are correct about that. I missed to specify the Source property of the Binding. Here is the updated binding:
foreach (MyKeyValueClass mkvc in propertyList)
            {
                radPropertyGrid.PropertyDefinitions.Add(new PropertyDefinition()
                {
                    DisplayName = mkvc.Key,
                    Binding = new Binding("Value") { Source = mkvc }
                });
            }

I am also adding the modified project for your reference.

Please let me know if you have any further questions.

Regards,
Vladimir Stoyanov

Hello,

I am doing the same but I also want to display the nested properties coming from the Value in MyKeyValueClass. How can I display nested properties?

Hello Monique,

I've updated the project Vladimir provided to demonstrate a possible approach for binding nested properties which are a part of the MyKeyValueClass. I've done this by adding new PropertyDefinitions to the parent definition's NestedProperties collection.

            foreach (MyKeyValueClass mkvc in propertyList)
            {
                var propertyDefinition = new PropertyDefinition()
                {
                    DisplayName = mkvc.Key,
                    Binding = new Binding("NestedKeyValuePair") { Source = mkvc },
                };
                propertyDefinition.NestedProperties.Add(new PropertyDefinition()
                {
                    DisplayName = mkvc.NestedKeyValuePair.Key,
                    Binding = new Binding("Value") { Source = mkvc },
                });
                radPropertyGrid.PropertyDefinitions.Add(propertyDefinition);
            }
Please have a look and let me know if a similar approach would work at your end.
