Hi

Please Help

Language: VB.Net (VS2017)

I am printing from radGridView with RadPrintDocument. Please advise how to add row numbers in the printpreview/print document.

In radGridView, row number is there in Row Header.

Hi,

I have a RadGrid containing a self-referencing hierarchy of data. All works perfectly. 

However, when it comes to styling, I am using one of the standard theme. However, I would like to change the default images for the expand/collapse arrows for showing/hiding the child elements, but nothing else .

How do I go about handling this?

Regards

Thomas

I am trying to disable HTML-like text formatting for appointments in a Scheduler that I have, but so far nothing is working. I have tried setting the DisableHTMLRendering property to true for myScheduler.ViewElement, myScheduler.SchedulerElement and have even tried it in the CellFormatting event handler where I set the property for mySchedulerCellEventArgs.CellElement. I am getting the same results in my main project as well as in a new test project that I created.

Thanks - Logan

All,

A simple question regarding the Calendar for the RadDateTimePicker using Microsoft WinForms.

The behavior I'm trying to fix is this:

I've put a KeyDown handler on the parent RadDateTimePicker that filters out backspace presses (since we don't want them in that control or any hosted controls in it). This appears to work fine (I can see the handler fire when this control has the focus). The RadDateTimePicker also has a hosted calendar control that can be accessed via a mouse click. When clicking on the UI element to get the popup Calendar, it properly pops up.. but when in the Calendar, if I now press the Backspace key, the Calendar popup disappears (this is the undesirable behavior).

I've tried this type of C# code to override keydown for the popup RadCalendar to get it to ignore Backspaces and it does not appear to work (I'm using exactly the same handler for now since I know it works):

            this.m_radDateTimePicker = new Telerik.WinControls.UI.RadDateTimePicker();

            //other initialization of the m_radDateTimePicker..

           Telerik.WinControls.UI.RadDateTimePickerCalendar calendarBehavior = (this.m_radDateTimePicker.DateTimePickerElement.GetCurrentBehavior() as Telerik.WinControls.UI.RadDateTimePickerCalendar);
            Telerik.WinControls.UI.RadCalendar calendar = calendarBehavior.Calendar as Telerik.WinControls.UI.RadCalendar;
            Telerik.WinControls.UI.RadCalendarElement calendarElement = calendar.CalendarElement as Telerik.WinControls.UI.RadCalendarElement;
            calendarElement.KeyDown += new System.Windows.Forms.KeyEventHandler(this.RadDateTimePicker_KeyDown);

I've tried this also on the RadCalendar (calendar.KeyDown += ...), to no effect.  Where should I place KeyHandler to get the popup Calendar to ignore Backspaces?

Thanks for your attention,

Richard

I need to draw 2,520 square shapes on a RadMap. I have the  locations (let, lng) of each square. They should have different colors (as in the attached image)

 When I use polygons to draw the squares, I face 2 issues:

(1) it takes very long time to complete the drawing of 2520 squares,

(2) I run out of memory as this process takes over 3 GB of memory.

Is there a better way to do this task?

I have tried to use <span style="font-family: 'Segoe UI'; color:gray; font-size: 12">Forename</span> but I do not believe the font is being applied. I use this style when the row is selected within a WinForms RadGridView. If the row is not selected (as a test) I have the same HTML markup without the font-family style and a different font is loaded (not sure which).  

The screenshot shows the highlighted row in purple. Notice the lower curl of the g and y is present - whereas on the unselected rows - these letters have that part missing.

Note: The rendering of the grid take a very long time - as if it is failing to render rows with this font and so falls back to a default

Could you explain the problem?

I am trying to work on a scheduler interface that will allow a user to enter appointments.

The system is working when I apply no filter and load data through the following:

try
{
entities.Appointments.Load();
schedulerBindingDataSource1.EventProvider.DataSource = entities.Appointments.Local.ToBindingList();//filteredAppointmentsByLocation;
this.radScheduler1.DataSource = schedulerBindingDataSource1;
}

The above works and allows me to add, edit and delete without issues.

If I try to add a filter to get specific information:
var filteredAppointmentsByLocation = entities.Appointments.Local.ToBindingList().Where(x => x.LocationID.Equals(ActiveLocation));

and set this as the datasource, I cannot add new items when I do entities.SaveChanges().  I get an error saying it cannot add to a read-only or fixed-size list.  Edits are saved, deletes are not done.

Please advise

So I use the RadAutoCompleteBox to list many options a user can pick that are then added to another textbox.

So once they select it, I take that "Token" and copy it to a "Selected Box".

How would I go about Removing the token after I have copied it in the token validating event.

Thanks
