Child Row Selection

I am trying to obtain the value of a cell in the current selected row in the child grid. There is no problem in getting that in the Parent using the CurrentRow, but I do not see CurrentRow in the Child as an option.

Scheduler resources in timelineview resets RangeStartDate

Hello,

i found this post
http://www.telerik.com/forums/grouping-appointments-in-timeline-view

and I have the same problem as desrcibed in the 4th post by Tom.
When I set the hour range to start any time of the day, it works fine, but if I enable Resources via GroupType property,
it goes back to 00:00.

For instance if the RangeStartDate and RangeEndDate are set to 2014-07-22 09:00 -> 2014-07-22 15:00,
when I set Me.Scheduler.GroupType = GroupType.Resource it will be 2014-07-22 00:00 -> 2014-07-22 06:00.

In the previous post I mentioned, Anton said there is no way to fix this.
This is a 10 month old post.
Is there any way to achieve this now?

Thanks.

RadForm TitleBar Buttons

There are two issues. The first is that if I set HelpButton to true, a help button doesn't show. Here are the relevant settings on my RadForm:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.Sizable;

this.HelpButton = true;

this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));

this.MaximizeBox = false;

this.MinimizeBox = false;

Additionally, I'm trying to add another button that behaves like the minimize/maximize/close button to the title bar. Basically, I want an image button that doesn't show it's fill or it's border until it's hovered/clicked, and is the same size as the minimize/maximize/close buttons. I need to be able to choose what happens when this button is clicked and what image is displayed.

Is there a simple way to accomplish this?

Calendar Special Days Properties

The Special Days properties are having no effect.

Disabled = true - Expected it to grey out the day. I get a normal, still selectable special day.
Selectable = false - Expected that when that day is clicked no selection occurs - I get a normal, still selectable special day.
Selected = false - Expected the day not to be highlighted - I get a highlighted special day.

Toggling these properties to true or false seems to have no effect. The special day is still enabled, selectable and highlighted.

The other properties seem to function ok. Setting the date of the day, recurring and the tooltip are ok.

Am I missing a setting? misinterpreting the behaviours?

Tested using a new standard winforms application.

Wordwrap in RadTextBoxControl

Hello,

Is there an update for wordwrap in the RadTextBoxControl or and idea when it might be fixed. I have voted for it in the Issue Tracking service.

Essentially it wordwraps but splits the word mid-way instead of using whole words.

Many thanks

Setting DataSource property leaves an empty Items collection

I have created a custom control wrapper for the DropDownList. My main reason was to create some shortcut methods for custom objects that we are using to populate the list.

I am trying to write some automated tests for my custom control. The problem is that when I create an instance of the custom control in the automated test (but not actually put it on a form or control), some of the data functionality is lost. I can set the DataSource property (using a list of my custom objects), but the Items collection still shows a count of 0. I can set the SelectedIndex proprty to a valid value, but the SelectedItem property remains null. When I do this same thing with an actual control on a form, the Items collection is populated and reflects what I set in the DataSource property.

I assume that the DropDownList is borrowing some functionality from the form to tie the DataSource and Items properties together.

Is there something additional that I can do to make the DropDownList fully functional in an automated test, or is this not possible?

I have tried using the Rebind method and this does not help. I also tried not using my custom control and just creating a RadDropDownList object directly in my automated test and it behaves the same way.

Selected Item content does not reflect the multiple-field-display done in VisualListItemFormatting

Hello,

I've got a winform rad dropdrown list and all the dropdown items' content appear as expected when I combined 2 data-fields following the instruction in this thread:
http://www.telerik.com/forums/multiple-field-displaymember

Specifically, mine case is:

args.VisualItem.Text = row["LastName"] + ", " + row["FirstName"];

So far so good.

However I think I still have to set a field to my rdd's MemberDisplay, that is:

rddlPaList.DisplayMember = dsResultPa.Tables[0].Columns[2].ToString(); //string - LastName (1) rddlPaList.ValueMember = dsResultPa.Tables[0].Columns[3].ToString(); // (interger value - ID) (2)

If I don't have the DisplayMember explicitly set as done in line (1) - in other words, if I remove line (1) >> as the rdd loads, the ID shown up for the selected item, i.e. 142, because of what's being done in (2) - I need (2) to happen, so I must keep that line.

But if I have both lines of codes, then the selected item get the Last Name displayed. I want it to display Last Name, First Name as well.

How can I achieve that?

Again, although all the items in the dropdown do get rendered in the format I implemented in the VisualListItemFormatting event handling codes, which is LastName, FirstName, the current item in "the box" has only Last Name displayed and it's getting a bit frustrated. What am I missing? Please help!!!

Add Hyperlink to TableCell

I'm attempting to add a Hyperlink to a Table and need some guidance on how to implement correctly. Below is the method that I'm using that I modified from another post. When it runs it appears to add the row correctly however all I see are blank lines in the cells that contain the Hyperlinks.

01.private TableRow AddNewRow(object[] items)

02.{

03. TableRow newRow = new TableRow();

04. for (int i = 0; i < items.Length; i++)

05. {

06. TableCell cell = new TableCell();

07. Paragraph paragraph = new Paragraph();

08. Span span = new Span();

09.

10. if(items[i] is string)

11. {

12. var newString = items[i] as string;
