Sorting Items

I've been trying to get my listview to sort in unbound mode (where I've added several items manually) and I can't seem to get it working.

I've tried:

uiMasterColourList.SortDescriptors.Add(new SortDescriptor("Text", ListSortDirection.Ascending));

uiMasterColourList.EnableSorting = true;

Basically I'm loading a list of colours from the database and then adding them to two different groups in the listview, along with a checkbox to see if the user has already selected the colour. Works great, but the colours end up a little mixed up and it'd be nice to sort them alphabetically inside their groups.

So this seems like a fairly simple problem, but I seem to be missing something that's making it not work.

Drag & Drop insertion lines on ListView

Hello, when using the AllowDragDrop=true on a ListView control, it gives to user a beautiful feedback while doing drag/drop (attached image).

Since i need to implement drag & drop manually, would be possible to draw insert lines on the listview control in "list" view mode?

Would be nice to also have the semiopaque cursor while dragging like on the attached image, but that is not that necessary to me.

The lack of insertion lines in my opinion make not clear for the users where the item will be dropped.

Best Regards

Andrea

Moving controls inside LayoutControl with a mouse

While we can move controls contained inside LayoutControl by selecting them and using the keyboard arrow keys it appears it is not possible to move them using the mouse since LayoutControl tries to automatically create a new section as soon as you start dragging a control with your mouse instead of allowing you to reposition the control within the existing section it is currently in. However, only when you use the mouse to move the controls the alignment lines show allowing you to align your controls more easily.

Why is it and is there a way to move the controls inside the LayoutControl with the mouse without LayoutControl automatically adding new sections?

[Solved] ColumnChooser now topmost in 2011Q3

Hi,
I find it rather annoying that the column chooser is now a topmost window.
The column chooser should be in front of all application windows from the app that called it but not on top of any other application.
What do other users think?

Regards

DataBinding Problem

Hello,

I've noticed a small problem with the commandbar controls and databinding. Maybe this is not a bug, but however the commandbar controls behave different to the "normal" (Telerik) controls.

If you have something like this:

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

{

public RadForm1()

{

InitializeComponent();

List<myobject> source = new List<myobject>();

BindingSource binding = new BindingSource();

source.Add(new myobject(1, "a"));

source.Add(new myobject(2, "b"));

source.Add(new myobject(3, "c"));

source.Add(new myobject(4, "d"));

try

{

commandBarTextBox1.DataBindings.Add("Text", binding, "MyProperty2", true, DataSourceUpdateMode.OnValidation);

}

catch

{

}

radTextBox1.DataBindings.Add("Text", binding, "MyProperty2", true, DataSourceUpdateMode.OnValidation);

binding.DataSource = source;

binding.MoveLast();

}

public class myobject

{

public int MyProperty1 { get; set; }

public string MyProperty2 { get; set; }

public myobject(int a, string b)

{

MyProperty1 = a;

MyProperty2 = b;

}

the databinding of the commandbartextbox will crash but the radtextbox works fine.The problem is that the binding datasource is set after the control databinding.

Since the radcontrols and the .net controls work fine in this case it would be nice if the commandbar controls could too.

(Why are the commandbarcontrols not derived from the radcontrols? or at least have the same base class?)

Kind Regards,

Christian

AllowSearchRow with Progress 11.6.2

Hi,

I'm on Progress OpenEdge 11.6.2 and tried to enable AllowSearchRow in a Grid. The code compiles and my form is shown and looks like expected.

When I now type a letter in the search field, I get an Error that the used type of multithreading is not supported (Error 15740) with ABL (the exact Message is in german language).

Is there a way to use this feature with Progress ABL?

Regards

Jürgen

Mail merge with several rows data

Hello,

I would like to insert in the same page data imported from several rows of a DB table.

Usually, the system creates one page per DB record. If I am using a master-detail structure, I have data coming from details table and the rows are more then one.

How can I manage this issue?

Thank you

CurrentCell in RadGridView errors out when not in visible view

I have a radgridview in WinsForm. I created data entry number pad (buttons) for the user interface. When the table loads up, the current cell (focused cell) is set to the first cell in the upper left. When the user presses the number pad button, it enters the data to the currentcell's value. It works all fine and dandy until the table gets bigger and requires scrolling to see other cells. My problem is, when the user scrolls away from the currentcell and the currentcell is not in sight there will be an error if any button referencing the currentcell is pressed. It seems that when the currentcell is not in view, it cannot access the currentcell. Is there a way around this or resolve this?

Reading child nodes on any check or uncheck

Hi I have following tree structure with checkboxes. I wanted to read the child notes selected or unselected and based on that I want to update a string which store those values

Tree structure

Parent1 ((checked))
   --Child11
   --Child12 (checked)
   --Child13 (checked)

Parent2(checked)
   --Child21 (checked)
         --Child22
   --Child23

Parent3 (checked)
   --Child31
   --Child32 (checked)
   --Child33

Dim ParentsNodes as string

Dim ChildNodes as string

I want to loop through entire node with any check or uncheck event and update my ParentNodes string and ChildNodes string so that it says

ParentsNodes = "Parent1, Parent2, Parent3"

ChildNodes = "Child12, Child13, Child21, Child32"

How do I loop through my nodes in RadTreeView using VB.NET and in what event should I put this loop so that any check or uncheck updates my strings. Please help

Thank you!
