[Solved] Self Reference Hierarchy not working on child template

Self Reference Hierarchy only seems to work on MasterTemplate. I would like to have the following hierarchy:
Group
> Category
> Category
> Product
Where category can have any number of levels. If I make MasterTemplate the categories and then AddSelfReference, it works fine, but if I have groups at the MasterTemplate level and then have a CategoryTemplate and AddSelfReference I only get one level of categories.

GroupCategory relation is Group.id = Category.groupId

I have tried this:
this.radGridView1.Relations.AddSelfReference(this.CategoryTemplate, "id", "parentId");
and
this.radGridView1.Relations.AddSelfReference(this.radGridView1.Templates[0], "id", "parentId");
and these both show only one level of categories.

With categories at the root (MasterTemplate) this works:
this.radGridView1.Relations.AddSelfReference(this.radGridView1.MasterTemplate, "id", "parentId");
I get several levels of categories.

Drag and Drop in ListControl Will not fire

Hi:

I'm trying to use the ListControl. I have two on my form and I use the DragDropManager to join them. However, it seems that I am unable to get any of the events associated with drag and drop to fire. I've created them using the properties list and everything in code is correct. Yet if I put a break point in the dragdrop event, it never gets there. (allow dragdrop is set to true).

Anyone know what gives ?

Thanks,
Ken

Get Appointment ID on doubleclick

I have a custom Appointment dialog because the one I use is very different from the default. I'm interrupting the default dialog by using e.cancel in RadScheduler1_AppointmentEditDialogShowing, and then displaying my custom form. This works great for new appointments but I need it to populate existing appointments when they are selected in the calendar. How can I retrieve the SQL ID of the appointment being selected? I need to pass this value to my custom form.

[Solved] SpellChecker not working on subclass of RadTextBox

Hello,

I would like to use the functionality of the RadTextBox and SpellChecker, but I also need to use my framework's databinding interface. So I created a subclass of the RadTextBox control and implemented the interface for binding.

public partial class SFRadTextBox : RadTextBox, IBusinessBindable

After calling spellChecker1.Check(sfRadTextBox1) I get the following error:

NotSupportedException

No spell check for GKGInc.i2Catalog.Controls.SFRadTextBox is not supported. 

   You should implement IControlSpellChecker interface.

Source : MicroFour StrataFrame Business

Stack Trace:

at Telerik.WinControls.UI.RadSpellChecker.Check(Control editControl)

Why isn't it picking up on the fact that the base class has the IControlSpellChecker interface implemented arleady?
Can someone please tell me what I'm doing wrong here and what I should be doing to get this working.

Thank You,
Govinda

[Solved] Formatting on a column's value change

Hello

In a Gridview, is there a way to use the same kind of tool than ".IsOdd", but applied to a particular cell's data? In short, I want the row color to change everytime the value in a particular column changes. Said columns happens to be my "ORDER BY" column.

private void radGridUsagers_CellFormatting(object sender, Telerik.WinControls.UI.CellFormattingEventArgs e)

{

e.CellElement.DrawFill = true;

e.CellElement.GradientStyle = GradientStyles.Solid;

if (e.CellElement.ColumnInfo.ReadOnly)

{

if (e.CellElement.RowElement.IsOdd)

e.CellElement.BackColor = clsColor.ReadOnlyOdd();

else

e.CellElement.BackColor = clsColor.ReadOnlyEven();

}

else

{

if (e.CellElement.RowElement.IsOdd)

e.CellElement.BackColor = clsColor.WritableOdd();

else

e.CellElement.BackColor = clsColor.WritableEven();

}
