[Solved] Nested DockingManagers

I have a docking manager on the main form. I have a docking manager in each dynamically generated document pane. How can I restrict docking of panels in the document pane to the docking manager of the same document pane? I don't want the user to be able to drag dockables from one docking manager to another...

Refresh radGridView

Hi All,

I have a radGridView that is populated via a TableAdapter:

    
            buUserTableAdapter buUserTA = new buUserTableAdapter();  
        
            protected BindingSource buUserBindingSource = new BindingSource();  
        
            buUserBindingSource.DataSource = buUserTA.GetData();  
        
            this.radGvAdminUsers.DataSource = buUserBindingSource;

The radGridView is read only, however, I have a "detail" section below the radGridView where users can edit the contents of the records. The database is updated upon clicking a "save" button via a stored procedure of the TableAdapter:

    
            private void radBtnAdminSaveUser_Click(object sender, EventArgs e)  
        
            {  
        
                int userId = Convert.ToInt32(lblAdminUserDBID.Text);  
        
                string userLogin = this.radTxtAdminLoginId.Text.ToUpper();  
        
                string lastName = this.radTxtAdminLastName.Text;  
        
                string firstName = this.radTxtAdminFirstName.Text;  
        
                string userPhone = this.radMTxtAdminPhone.Value.ToString().Trim();  
        
                int userRole = Convert.ToInt32(this.radComboAdminRole.SelectedValue);  
        
                string userRoleDesc = radComboAdminRole.Text;  
        
                bool userActive = Convert.ToBoolean(this.radCbAdminUserIsActive.Checked);  
        
                if (userId != 0)  
        
                {  
        
                    buUserTA.UpdateSP(userId, userLogin, lastName, firstName, userPhone, userRole, userActive, System.Configuration.ConfigurationManager.AppSettings["UserNetworkId"].ToString());  
        
                }  
        
                else 
        
                {  
        
                    //Need to do an insert for a new user and update for the new id  
        
                    userId = Convert.ToInt32(buUserTA.InsertSP(userLogin, lastName, firstName, userPhone, userRole, System.Configuration.ConfigurationManager.AppSettings["UserNetworkId"].ToString()));  
        
                }  
        
            }

When this is clicked, the database is properly updated, however, the radGridView does not refresh to reflect the changes.

From what I've read, it seems like the radGridView is supposed to automatically updated. What am I missing or doing wrong? Any help with this is greatly appreciated.

Do not allow user to select item

Hello,

I would like to not allow the user to select an item in my radListBox. I have set the selection mode to none, but this still places a border around the edge of the item. How can I ensure that items do not show as selected in any visible way?

Thanks

Best Fit each gridview column based on the record stored

Hi,

I have been facing problems adjusting the column length to best fit based on the maximum data present in any of the columns field.

i.e.

the column should automatically maximize to the maximum length of the records in that column

Can you please Help me out, as currently all of my columns are compressed and i have to manually expand each column to have a look at my data.

Note: My gridview is being populated by list using the (datasource) property.

Hiding The Menu Bar

I'm looking for a way to toggle hide and unhide for the menu bar on an application. I want it to toggle when the user presses 'Alt' just like on Internet Explorer 8.
All attempts I have made so far have failed. Capturing KeyDown has a tendancy to make the toggling flicker if the Alt key is pressed too long. Also, the menu toggles if the user trys ALT+Tab or any other Alt key function.

After install process, I ran my application and failed process before load ribbon form.

I think my msi file have some problem about telerik dll files.

Do you have any suggestions about that? Actually I didn't use msi file before.

[Solved] Custom Items

I have created a new EditAppointDialog form, using a custom Appointment Factory. C#

1) How can I set the new custom appointment data during manual creation? I don't see "Email" show as an option. Am I missing something? The email data does save & load within the session.

Appointment appointment = null;

appointment = new Appointment(start, end, summary, description, location);

this.radScheduler.Appointments.Add(appointment);

this.radScheduler.AppointmentFactory = new CustomSchedFactory();

public class CustomSchedFactory : IAppointmentFactory

{

#region IAppointmentFactory Members

public IEvent CreateNewAppointment()

{

return new MySched();

}

#endregion

}

public class MySched : Appointment

{

public MySched()

:base()

{ }

string email = String.Empty;

public string Email

{

get { return this.email; }

set

{

if (this.email != value)

{

this.email=value;

this.OnPropertyChanged("Email");

}

2) I also will have a new combobox added to the custom AppointmentDialog, and I want to add items at form load (similiar to Resources). How I can I add drop-down values to my custom combobox on the radScheduler during Onload of RadForm (not Appointment form)?

this.radScheduler.Resources.Add(new Resource(1,"Test"));

(I have a new "Types" combobox on the custom EditAppointmentDialog)
