Do not find ItemOffset property for radribbonbar commandtabs

Hi,

I am using the radribbonbar commandtabs in my page. But I didn't find the itemoffset property for the commandtabls just like we have for radtabstrip. My tabs are starting by leaving some blank space initially. In radtabstrip we set the itemoffset property to remove that space. Is there any way to remove that space in commandtabs.

Thanks,
Ashish K

How to add 4 level hierarchy to radgrid in winform

Hi All,

I am using gridview in my desktop application.
I want to show a hierarchical grid in the following manner,

+ Great-GrandFather
            +GrandFather
                       +Father
                                                 Children

My dataset has 4 tables like table1,table2,table3 and table4.
I am assigning the dataset to my gridview as

    
             ds = getGrandparent_to_child_Dataset(); 
        
            //this will return me a dataset with 4 tables 
        
            mygridview1.DataSource = ds; 
        
            mygridview1.DataMember = ds.Tables[0].ToString();

Now I am getting a hierarchy upto three level i.e. upto Father

So please help me to find out how to get Children also in Gridview i.e. 4th level of grid

Thanks in Advance
Rahul K.

SelectedIndices

In the Q1 release of the Telerik WinForms the

listbox.SelectedIndices

is gone. Is there a equivalent or do i have to check against the values?
since i'm working with a static list in this case the index is the ID of the item, and
the performance of caching the indices is better than getting the object values of the raditem.
(Multiselection of course)

What do you guys suggest?

BeginUpdate suspend events ?

Hi!

I'm having some troubles with my radcombobox. In the loading of my form I add the items dynamically in my radcombobox. But when I do so, the SelectedIndexChanged event is fired. To avoid this I have try to use BeginUpdate() and EnUpdate() methods but it does nothing !
How could I supend the events while I'm loading the items of my combobox ?

Thanks in advance,

Problem with DataSource

Hi,
I used your class MyAppointment in your trial example...

This is my code :

String query;

query ="Select * from myTable";
SqlConnection myConn = new SqlConnection("Data Source=MyServer;Initial Catalog=MyCatalog;User Id=MyUser;Password=MyPassword;");
SqlCommand cmd = new SqlCommand(query, myConn);
SqlDataReader read;
myConn.Open();
read = cmd.ExecuteReader();
while (read.Read())
{
MyAppointment app = new MyAppointment(Convert.ToDateTime(read.GetString(2)), Convert.ToDateTime(read.GetString(3)), Convert.ToString(read.GetInt32(0)), read.GetString(1), read.GetString(4));

appointments.Add(app);
}
myConn.Close();

SchedulerBindingDataSource dataSource = new SchedulerBindingDataSource();
AppointmentMappingInfo appointmentMappingInfo = new AppointmentMappingInfo();
appointmentMappingInfo.Start = "Start";
appointmentMappingInfo.End = "End";
appointmentMappingInfo.Summary = "Subject";
appointmentMappingInfo.Description = "Description";
appointmentMappingInfo.Location = "Location";
appointmentMappingInfo.UniqueId = "Id";
SchedulerMapping idMapping = appointmentMappingInfo.FindByDataSourceProperty("Id");
dataSource.EventProvider.Mapping = appointmentMappingInfo;
dataSource.EventProvider.DataSource = appointments;

this.ux_cedule.DataSource = dataSource;

But I have error message : impossible to convert object 'System.GUID to 'Telerik.WinControls.UI.EventId' type. Do you understand wath is my problem?

Thanks a lot again

Problem with Grouping and GridViewCheckBoxColumn

Hi,

I have 7 columns and one gridviewcheckboxcolumn. I am grouping with "GroupByExpression". I have three expressions in order to group by the three columns. So, I have the "AutoExpandGroups" and "ShowGroupedColumns" properties to FALSE.

The problem is the following:

When I set one cell checkbox to true, and I am going to set other cell checkbox to true, I don't know why, but all the groups are expanded.

Please, help me!

Thanks,

GridView

Issues manually entering a date into DateTimePicker

Just trying out the Telerik Controls for Win Forms to see if it is worth switching to them from the ones I currently use. However I had a couple of problems when trying to manually enter dates on the DateTimePicker. I found that if the date has been set to the null date by hitting the DEL key, then you tab off the control, then you cannot type in a date when you tab back to that control. Also the DateTimePicker does not recognise partially entered years i.e. 1/1/08 for 01/01/2008.

Is there a way to get around these issues?
Thanks
