Hi,

Loading the propertygrid using RadPropertyStore and PropertySort.CategorizedAlphabetical has become slow in the recent versions.

The performance is Ok, when using PropertySort.NoSort

(100 items, 10-15 categories)

Using version 2014.1.226.40

MouseMove Listview

When I use the mouse on the [MouseMove] event, I can retrieve a value if I am in Columns, details, and scroll?

I have a problem with ListView DoDragDrop not allow me to slide the scrool or columns.

Code:

private void lvwDetalle_MouseMove(object sender, MouseEventArgs e)
{

if (this.mouseDown && !this.dragged) {

Point pt = this.lvwDetalle.PointToClient(Control.MousePosition);

this.dragged = true;
List<ListViewDataItem> selectedItems =
this.lvwDetalle.SelectedItems.ToList<ListViewDataItem>();
if (selectedItems.Count > 0) {
//DragDropEffects.

this.lvwDetalle.DoDragDrop(selectedItems, DragDropEffects.Move);
}

}
}

Hello,

I would like to activate a dockwindow by dragging something over the tabstrip.

Could this be achieved by a simple property or do I have to code it?

UserControl within DocumentWindow not visible after LoadFromXml()

I have a single DocumentWindow that I am using to host my own tab control to display a set of tabs. Prior to calling the LoadFromXml() method to restore a docking layout, I can perform actions within my app that correctly adds tabs to my own tab control. See attached image "Document Windows - Before Load Layout.jpg". However, after I call "LoadFromXml()", my tab control disappears. See attached image "Document Windows - After Load Layout.jpg".

I can inspect the "Parent" property of my tab control, and it is still set to the "DocumentWindow", but my tab control does not show up in "DocumentWindow.Controls" property. If I force adding my tab control back into the "Controls" list for the DocumentWindow, I still do not see my tab control on the screen.

Can you offer a solution and best practices for how to restore my user controls within a DocumentWindow after a call to LoadFromXml()?

Thank you.

How to Save Appointments at database

I need Use a InSERT INTO Statement...

My problem is, after I insert an Appointment to appointments table. the radscheduler shows nothing... if I delete this record(manually added) and try showing data again, the appointments appears again..

that no sense, if I have data in database, and the scheduler fill datasets based in database,,, why if I add manually a record, no appointments are showed?????

I tried too, copy and paste a valid stored appointment in a new record with another autonumeric and the same behaviour,,

I tried too copy and paste this record and change the start and end date(to avoid possibles duplicated problems)

Then, I just need add appointments in database level..... no in the form with the scheduler...

I follow this example.. or better i use that project and them improved this

Update: Another Question, I get this error "Cannot set column 'Description'. The value violates the MaxLength limit of this column."
Which is the limit of caracters? of this field???, Is possible make larger the description?

thanks

Missing column Issue with RadGridView when bounded to a DataSource

Hi,

I bind the datasource of RadGridView to a datatable.
The datatable only contains 2 rows but 260 columns.

The problem is that a column is missing in the ui grid.

I used the steb by steb debugger to watch values :

dt = GetData(); //dt contains 260 columns
RadGrid.DataSource = dt; //RadGrid.DataSource contains 260 columns

BUT!!! RadGrid.DataSource.Columns contains 259 columns!!!

What's wrong?

Thank you,

Kind Regards.
