Group Panel Printing

I have code:
RadGridView1.TableElement.GridViewElement.GroupPanelElement.Text = "Some Text"
RadGridView1.TableElement.GridViewElement.GroupPanelElement.TextAlignment = ContentAlignment.TopLeft

and I want to print my GroupPanelElement.Text along with my GridView. Is this possible? and if so can someone please provide the code to to do this.

I tried:
RadGridView1.TableElement.GridViewElement.GroupPanelElement.GridControl.PrintStyle.PrintGrouping = True

But that doesn't work.

Thank you in advance,

Curtis

gridview load on demand

hi
I'm working on an application that in one part of this, we have to display physical disk content in grid for user.
we have a cache(reduce disk access and increase performance) that load 10 kilo byte of data and use it in CellValueNeeded event of radGridView1 as below

private void radGridView1_CellValueNeeded(object sender, GridViewCellValueEventArgs e)
{

try
{
e.Value = cache.retriveCellElement(e.RowIndex, e.ColumnIndex);
}
catch
{
MessageBox.Show(e.RowIndex.ToString() + " + " + e.ColumnIndex.ToString());
}

}
but when the rowCount of radGridView1 greater than 1000000 this is very slow and when rowCount greater than 2000000 radGridView1 doesn't show anything. is there any limit on rowCount? is there any alternative solution in this case?
Thank you in advance for your help.

fa-Ir Culture in RadDateTimePicker problem

hello,
I am using Q2 2011 and want to have a Persian DateTimePicker but when I set RadDateTimePicker culture property to fa-Ir, an exception is thrown in this line:

this.radDateTimePicker1.Culture = new System.Globalization.CultureInfo("fa-IR");

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

I tried everything said in other forum threads like setting thread culture and calendar to persian :

CultureInfo info = new CultureInfo("fa-Ir");

info.DateTimeFormat.Calendar = new PersianCalendar();

Thread.CurrentThread.CurrentCulture = info;

this.radDateTimePicker1.Culture = info;

but I get the same exception at this line:

this.radDateTimePicker1.Culture = info;

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: index

Then I tried another code posted in MSDN forums:

System.Globalization.CultureInfo calture = new System.Globalization.CultureInfo("fa-IR");

System.Globalization.DateTimeFormatInfo info = calture.DateTimeFormat;

info.AbbreviatedDayNames = new string[] { "ی", "د", "س", "چ", "پ", "ج", "ش" };

info.DayNames = new string[] { "یکشنبه", "دوشنبه", "ﺳﻪشنبه", "چهارشنبه", "پنجشنبه", "جمعه", "شنبه" };

info.AbbreviatedMonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

info.MonthNames = new string[] { "فروردین", "ارديبهشت", "خرداد", "تير", "مرداد", "شهریور", "مهر", "آبان", "آذر", "دی", "بهمن", "اسفند", "" };

info.AMDesignator = "ق.ظ";

info.PMDesignator = "ب.ظ";

info.ShortDatePattern = "yyyy/MM/dd";

info.FirstDayOfWeek = DayOfWeek.Saturday;

System.Globalization.PersianCalendar cal = new System.Globalization.PersianCalendar();

typeof(System.Globalization.DateTimeFormatInfo).GetField("calendar"

, System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(info, cal);

object obj = typeof(System.Globalization.DateTimeFormatInfo).GetField("m_cultureTableRecord"

, System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(info);

obj.GetType().GetMethod("UseCurrentCalendar", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance).Invoke(obj, new object[] { cal.GetType().GetProperty("ID", System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).GetValue(cal, null) });

typeof(System.Globalization.CultureInfo).GetField("calendar"

, System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(calture, cal);

typeof(System.Globalization.CultureInfo).GetField("calendar"

, System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.NonPublic).SetValue(calture, cal);

System.Threading.Thread.CurrentThread.CurrentCulture = calture;

System.Threading.Thread.CurrentThread.CurrentUICulture = calture;

System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat = info;

System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat = info;

the same exception is thrown again in this line:

this.radDateTimePicker1 = new Telerik.WinControls.UI.RadDateTimePicker();

System.ArgumentOutOfRangeException was unhandled

Message=Index was out of range. Must be non-negative and less than the size of the collection.

How to add a column to display related data

I'm sure there's already an answer to my question in the forum, but I haven't been able to locate one:

In a WinForms project I'm using an entity framework entity that represents a table of invoice data: Project_ID, Principal, Interest, etc. Since I'm using an entity representation of a table, it doesn't include, in this case, the ProjectName located in the projects table. I want my grid to be based on the entity to use the framework's functionality to update the table, but I want a column next to the Project_ID that displays the related ProjectName. How can I accomplish this?

Thank you in advance for your help.
