Node not being removed from DataSource

Hi,

Spent some time today with the RadTreeView and can't figure out why a node is removed fine from the DS when using

radTreeView1.DisplayMember = "Name";
radTreeView1.ValueMember = "Id";

But not when using:

radTreeView1.DisplayMember = "Name\\ChildName";
radTreeView1.ChildMember = "list\\ChildObjects";

Regards,

Thomas

See code below:

namespace RadTreeViewTest

{

public partial class RadForm1 : Telerik.WinControls.UI.RadForm

{

BindingList<MyObject> list = new BindingList<MyObject>();

int counter = 0;

public RadForm1()

{

InitializeComponent();

list.ListChanged += List_ListChanged;

radTreeView1.DataSource = list;

radTreeView1.DisplayMember = "Name\\ChildName";

radTreeView1.ChildMember = "list\\ChildObjects";

//radTreeView1.DisplayMember = "Name";

//radTreeView1.ValueMember = "Id";

}

private void List_ListChanged(object sender, ListChangedEventArgs e)

{

radLabel1.Text = ""+list.Count;

}

private void radButton1_Click(object sender, EventArgs e)

{

list.Add(new MyObject(counter++, "Test " + counter, 5));

}

public class MyObject : INotifyPropertyChanged

{

private int id;

public int Id

{

get { return id; }

set { SetField(ref id, value, "Id"); }

}

private string name;

public string Name

{

get { return name; }

set { SetField(ref name, value, "Name"); }

}

private int counter;

public int Counter

{

get { return counter; }

set { SetField(ref counter, value, "Counter"); }

}

public BindingList<ChildObject> ChildObjects { get; set; }

public MyObject()

{

}

public MyObject(int i, string n, int c)

{

ChildObjects = new BindingList<ChildObject>();

this.Id = i; this.Name = n;this.Counter = c;

ChildObjects.Add(new ChildObject(i, "ghejwgk 1"));

ChildObjects.Add(new ChildObject(i, "ghejwgk 2"));

}

public event PropertyChangedEventHandler PropertyChanged;

protected virtual void OnPropertyChanged(string propertyName)

{

PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));

}

protected bool SetField<T>(ref T field, T value, string propertyName)

{

if (EqualityComparer<T>.Default.Equals(field, value)) return false;

field = value;

OnPropertyChanged(propertyName);

return true;

}

public class ChildObject

{

public int ParentId { get; set; }

public string ChildName { get; set; }

public ChildObject(int i, string n)

{

this.ParentId = i; this.ChildName = n;

}

GridView's default font issue in Office2010Black theme solved

Hello,

I encountered the following issue (and found a solution) with GridView when using the Office2010Black theme:

When the font of the parent form (RadForm) was set to let's say Segoe UI; 9,75pt; style=Bold and this form contained a RadGridView, then the font of the GridView root element even got this font settings and thus all texts of the grid view were displayed in the font of the parent window with the following visual result:

.http://www.incosol.de/images/TestProgWhIssue.gif

Reason:

In the RootRadElement of the RadGridView the Font property wasn't set to a specific text repository.

http://www.incosol.de/images/StyleBuilderOriginalThemeSettings.gif

Solution:

The font property of the RootRadElement of the RadGridView has to be set to a specific text repository.

Hi guys, how are You.

I have one quesition and I hope You guys can help me.

Ok, datasource in my radgridview is DataTable( filled with DataAdapter / query). < - I have to use this because quety is using PIVOT construct.

You can see the results of my query in attachment. Now You see that cells with the values? its 3 , 20, 8 , 10 etc. Now i want to change the color or what cell based on that value. Ex. if the cell value is 20 then 20 % of that cell should be Color.Red and so on, cell with Null value or 0 value should stay the same color ( default one ).

I hope You guys will understand my question.

RadDiagramShape Connectors always visible

Hi,

I am creating some custom RadDiagramShapes, using Shape -> Create new custom shape. I have also added custom connectors and configured the LightVisualElement child to display some text. (as in attachement)

Is there any way for these connectors to stay always visible in RadDiagram, even if shape is not selected?

I have tried to override the UpdateVisualStates method from RadDiagramShape, using VisualStateManager.GoToState(), with no success.

I am using .NET Framework 4.5.2 and Telerik 2017.3.912.40

Thanks!
