Custom gridview column issue

I've followed an example I found on your site for creating a custom gridview column.

https://docs.telerik.com/devtools/winforms/gridview/cells/creating-custom-cells

I was able to get it to work and populate, but only by manually editing the designer document of the form in which the grid was located. My column type, however, does appear on my list of column types but after adding it, and when I try closing the grid design window I get an error. Can you tell me what I'm doing wrong? Attached a screen shot showing my columntype in the list, the column added (column1), and the error message I received. Thanks for any help you can give me.

TrackBar - Disable trailing color

Hi. I'm looking to use the RadTrackBar as a selector for hours. For example, far left would be 0700 (7am) and far right would be 1400 (2pm).

I cannot figure out how to disable/turn off/colorize the TrackBarIndicatorElement behind the slider. I want just the bar with the slider. As the user moves it, there should not be any color displayed in the bar. Is that possible?

PageViewBackstage. Issue with highlighting 'selected item' with Border repository item

Hello Telerik,

I would like to customize RadPageView in mode Backstage. I like how it looks with 'TelerikMetro' theme, but I would like to change method for selecting active page - instead of using image (green arrow) I would like to use simple border on the left side. That what I am doing:
1. Open Visual Style Builder
2. Select RadPageView control and set it to Backstage.
3. Apply to 'TelerikMetro' theme.
4. Expand control tree and select 'RadPageViewStripItem' for customization.
5. Go to 'Element states' window for customization needed states for item. In my case I am looking all states where green arrow image is used. There are 'RadPageViewStripItem.Selected','RadPageViewStripItem.MouseDown' and 'RadPageViewStripItem.Selected.MouseOver'.
6. Disable repository item with green arrow.
7. Create new simple repository item - Border. For highlighting active tab.
8. And this is the issue - on preview, I see that when I select page, I have border for some pages that are not selected. It looks like the border line is too long. The same result I have if I try to use this changed theme in my project.

How I can change this and how to make border shorter, only for needed page item? I am really don't understand what causes this error.

I also uploaded video to - https://www.screencast.com/t/ZehV4cXj

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;

}
