Binding to RangeStart and RangeEnd of RadRangeSelector

My range selector represents the 100% length of a running track. RangeStart represents the position of the start line, RangeEnd is represents the end.

I tried databinding to the RangeStart and RangeEnd properties of my selector but, after the initial binding get/set there didn't appear to be any further property change events when I changed the ranges.

How do I bind please?

radRangeSelector1.DataBindings.Add(new Binding(

radRangeSelector1.GetMemberName(x => x.StartRange),

bs, this.GetMemberName(x => x.StartRange),

false, DataSourceUpdateMode.OnPropertyChanged));

radRangeSelector1.DataBindings.Add(new Binding(

radRangeSelector1.GetMemberName(x => x.EndRange),

bs, this.GetMemberName(x => x.EndRange),

false, DataSourceUpdateMode.OnPropertyChanged));

MultiColumn ComboBox - Selected Value

I have a multi-column combo box which is populated via a LINQ query to an entity in my context

//Grab the data from the table specified in the Model project
var query = from i in db.ItemTypes.AsNoTracking()
where i.Active == active
orderby i.Code

//This allows a switch between the ITNBR and the Description
select new { i.ID, i.Code, i.Description };

if (query.Count() > 0)
{
//Now we can bind the results to the control
cbo.DataSource = query.ToList();
cbo.ValueMember = "ID";
}

Which works fine and the data is populated correctly. I have used similar to populate other multicolumn combos elsewhere too.

As the form is instanciated the selected index is set to -1
The problem is when I go radMultiColumnComboBoxItemType.SelectedValue = 3 the SelectedValue still = null.

Any ideas folks?
Thanks.

Sometimes properties need reset to be overridden by a theme

Hello there,

I meet the following issue.. I've created a custom theme in Visual Style Builder and I am trying to apply it in runtime using the following line:

Telerik.WinControls.ThemeResolutionService.LoadPackageFile("C:/.../CustomTheme.tssp");
Telerik.WinControls.ThemeResolutionService.ApplicationThemeName = "CustomTheme";

The theme is being applied to most of the controls but not to all. I have solved this issue by subscribing to "Telerik.WinControls.ThemeResolutionService.ApplicationThemeChanged" event and there I reset manually the properties that are not being overridden by the theme.

But I guess that it's not necessary and I am doing something wrong.

I will give an example of my issue:

If I add a new RadButton to my Form and leave its Fill.BackColor to 'Transparent', then the theme is being applied properly in runtime. But if I change its BackColor from WinForms Designer, then the theme does not override its value and needs reset in ApplicationThemeChanged event with the method:

MyRadButton.ButtonElement.Fill.ResetValue(Telerik.WinControls.Primitives.FillPrimitive.BackColorProperty);

Any ideas?

Collapsing node during selection change

Hello,

I am looking to set up my TreeView in such a way as to have the previously-selected node collapse when a different node at the same level is chosen. For example, if I had a tree like this:

RootNode

|_ NodeA

| |_Node1

| |_Node2

|_NodeB

| |_Node3
| |_Node4

If I choose NodeA, NodeB (if expanded) would close, and NodeA would expand. I want to do this so that the end user doesn't get lost with many nodes expanded. Any ideas?

Thanks,

Matt

The size of the border is not the same and there is a problem.

The size of the border is not the same and there is a problem.
When the outer border is 3 and the inner border is 1, the top of the border will protrude and the bottom will lack pixels.
