Hi Telerik !
There is a bug with RadDateTimePicker.
1. Set RadDateTimePicker.Culture = ar-SA (To see Arabic date)
2. Run program.
3. Open drop down calendar.
4. Open year and month drop down list.
5. Now count how many months are there. There should be 12 months, but there is 11 months.
NOTE1: I should add that when you try to reach the missing month with left or right buttons, the object stucks, or drops the missing month.
NOTE2: Sometimes you can reach to missing month with FastForward or FastRewind buttons, but then another month will be lost.
I believe it is BUG !!!

hi,
What's the efficient way to insert a new line but to the first line of the grid?
it means all the exists rows will "push" below.
if you can refer me to example it will be great.
best regards,
Roy

Hi!
My application is standard WinForms Form with RadRibbonBar placed on that form. I set autoScaleMode to DPI for that form, ale unfortunately form and ribbon doesn't scale to 125 or 150%. Other forms are actually RadForms, and forms and all controls placed on themscales right. Is this have to be RadRibbonForm to scale right? Is this the only solution for my problem?
UPDATE: In fact form scales. Only ribbonbar and statusbar doesn't scale.
Cheers,
Kuba.

Hello,
I have a table with three fields: RowID, CustomerName and Selected. I am loading this into the gridview and I would like to programmatically select the row where Selected is true. If this was ASP.NET I would use the RowDatabound event and check the value of Selected and highlight. What is the best way here? After I load the list loop back through the data, get the one that is selected and then loop through the rows in the grid to select it? Seems like there would have to be a more efficient way of doing this.
Thanks,
Warren

When I tab through the controls in my form, and while tabbing through datetime picker Current Date is populated as value. I do not want to the control to enter any date without user selection. Also, I have a pair of datetime picker like start date and end date and each is of the control's Opened & Leave Events are utilized as below but without these also, the same issue occurs.
private void dtProdStartDate_Leave(object sender, EventArgs e) { if (dtProdEndDate.Text == String.Empty && dtProdStartDate.Value != DateTime.Parse("1/1/0001")) { DateTime dtStart = dtProdStartDate.Value; dtStart = dtStart.AddMonths(1); DateTime dtEnd = dtStart.AddDays(-dtStart.Day); dtProdEndDate.Value = dtEnd; } else { if (DateTime.Compare(dtProdStartDate.Value, dtProdEndDate.Value) > 0) { DateTime dtStart = dtProdStartDate.Value; dtStart = dtStart.AddMonths(1); DateTime dtEnd = dtStart.AddDays(-dtStart.Day); dtProdEndDate.Value = dtEnd; } } } private void dtProdStartDate_Opened(object sender, EventArgs e) { if (this.dtProdStartDate.Value == DateTime.MinValue) { ((RadDateTimePickerCalendar)this.dtProdStartDate.DateTimePickerElement.GetCurrentBehavior()).Calendar.FocusedDate = DateTime.Now; } }

I have add a couple of extra fields in a CustomEditAppointmentDialog.
When i select an appointment in the scheduler I want to put the information out of one of the extra
fields in a textbox on my form.
I can reach all the information in the standard fields from Appointment class. But i can't reach the
information of the extra fields created in the CustomAppointment class.
Can someone help me out how i can reach that information?
private void radScheduler1_AppointmentSelected(object sender, SchedulerAppointmentEventArgs e)
{
if (e.Appointment.Description != null)
{
labelCalendarCustomerNo.Text = e.Appointment.CustNo; //this does not work
labelCalendarCustomerName.Text = e.Appointment.Location; //this works
labelCalendarEnd.Text = e.Appointment.End.ToString(); //this works
labelCalendarStart.Text = e.Appointment.Start.ToString(); //this works
}
}
}
public class CustomAppointment : Appointment { public CustomAppointment() : base() { } private string custNo = String.Empty; public string CustNo { get { return this.custNo; } set { if (this.custNo != value) { this.custNo = value; } } }

Hi,
Is it possible to draw a filled polygon area (more than 4 points) on top of the grid.
Points inside the area is of special interest.

My need seems fairly straightforward, but after poring through help text, forum postings, example apps, and making many trials, I still can't make the whole picture work--I'm missing a couple of key pieces.
.NET C# Winforms, Telerik 2013.1.321.20
The RadGrid is unbound. The data is populated (so far) through creating a new row with "GridViewRowInfo row = Grid.Rows.NewRow(), and then iterating through the cells of the row and setting the value of the GridViewCellInfo.
I need multiple columns of a custom cell type. Each cell contains a multicolumn combo box bound to a datatable (the same for all cells), a text box or label to display a value, and a button. The combo box should display all the time (as would an individual one on the form), not just when the cell is selected. I need to catch the combo box change, and handle it, potentially through methods on the parent form. The label is display only. The button needs to open a dialog form with access to the info from the cell, and again I need to reach back to the parent form. I need to be able to change the formatting on cell initialization, for the selected cell, and when the data changes. And that's it. No new rows after initialization, no sorting, no filtering, no reordering columns.
I can create the elements in CreateChildElements on the cell, and I can arrange them in ArrangeOverride on the cell. I can do some formatting in the Grid_CellFormatting event.
So these seem to be my stuck places:
o I don't seem to be able to inherit my column from GridViewMultiColumnComboBoxColumn, because I need the combo box to show all the time, not just when the cell is in edit mode. AND because I cannot find a cell element for the Multi Column Combo parallel to GridComboBoxCellElement. I can bind and set up the combo box in Grid_CellBeginEdit, but in that case it only shows when it is in edit mode. So what is my best way to get the combo box set up for the cells? (Bind the datatable, set DisplayMember, and ValueMember, set up the MultiColumn grid dropdown, set an event handler.)
o I need to pass at least three values to the cell--the selected value for the combo box, the value to display in the label, and an ID. I believe I can pass all of these to the cell in a small object or tuple in the Value or Tag,. But how do I get them to populate the objects at the right time? I think I'm having some major misunderstanding between the logical cell and the visual cell. I need to store these values in the logical cell and populate the visual cell at the right time--but how exactly, because what I've tried has made everything confused, and the values changed on all the combo boxes at once.
o What is my best way to handle the SelectedIndexChanged or SelectedValueChanged event on the combo box and the Click event on the button, with access to (ideally) methods on the parent form and values from the cell? (I might be able to pass an object reference to the form or an object on the form in the tag, if there is no direct access to methods and properties of the parent form.)
o What is my best way to handle cell formatting, including formatting the controls within the cell (e.g., combobox backcolor) on initialization, on value changed, and on current? So far I haven't seen how to get to the child controls on the Grid_CellFormatting.
Any help will be greatly appreciated.
