I am using the Radcontrol Windows Grid to bind data returned by a 'Select' query.
The piece of code is something like this:

            SqlDataReader dr = null;
            SqlConnection conn = null;
            try
            {
                this.radGridView1.MasterGridViewTemplate.AutoGenerateColumns = true;
                this.radGridView1.GridElement.BeginUpdate();
                DataSet ds = new System.Data.DataSet();
                string connectionString = ConfigurationManager.AppSettings["Conn"];
                conn = new SqlConnection(connectionString);
                SqlCommand cmd = new SqlCommand("SELECT * FROM Payment");
                cmd.Connection = conn;
                conn.Open();
               SqlDataAdapter da = new SqlDataAdapter();
                da.SelectCommand = cmd;
                da.Fill(ds);
                radGridView1.DataSource = ds.Tables[0].DefaultView;
             }
            catch (Exception ex)
            {
            }
            finally
            {
                conn.Close();
                dr.Dispose();
            }
Although the dataset is returning rows as a resultset, but when the grid loads, it displayes nothing. Is there anything I am missing.
I want to Auto generate the columns.
Thanks,
Saikat

Grouping on more levels

If we add more GroupDescriptors to the collection. Only the first group will be displayed.

This is our code :

var descriptor1 = new GroupDescriptor(new[]{ new SortDescriptor("Country", ListSortDirection.Ascending) });

var descriptor2 = new GroupDescriptor(new[]{ new SortDescriptor("User", ListSortDirection.Ascending) });

radListView1.EnableGrouping = true;

radListView1.ShowGroups = true;

radListView1.GroupDescriptors.Add(descriptor1 );

radListView1.GroupDescriptors.Add(descriptor2 );

Do we still have to do something extra or is this not supported yet?

Kind regards,

Kim

RadApplicationMenu vs RadCommandBar vs RadMenu vs RadRibbonBar

Are there any guidelines on when to use RadApplicationMenu/ RadCommandBar/ RadMenu/ RadRibbonBar?

I want a tool bar interface at the top of my form (without any drop down menus). All items will have an image and some text. And I also want accelerator key support (put an "&" in item text to underline an alphabet and create a short cut key).

With so many choices, I am not sure which of these is the best control to use.

Most of the above is achievable using RadCommandBar, but it does not have accelerator key support.

Regards.

Default Alignment

Hi,

How do I set the default alignment of the command bar to the right?

For example see attached screenshot "before".
What I want to do is display the commandbar on the right by default as shown in screenshot "after".

I have tried setting the Alignment property of CommandBarStripElement to "TopRight", but this does not make a difference.

Regards.

Display Business object containing list of another business objects

Hi -

I'm binding my ListView to a class that contains a list which is a list of another class.

For instance,

public class Person

{

public List<Orders> Orders {get; set;}

}

public class Orders

{

public Guid Id {get; set;}

public string {get; set;}

}

When I bind the ListView to an instance of the person class, how could i display specific value for one of the orders on the row that displays for the person class?

Thanks -

Multiple rows cannot be pinned simultaneously

Hello all,

This is my first post after i started working with Telerik Radcontrols for winforms.
Currently i would like to select multiple rows from the grid and i would like to pin them all (either at top or bottom).

At present, eventhough it is possible to select multiple rows, only the first row is pinned.

Is it possible to extend the rad grid row header context menu, item click event handler ? such an event handler is really available in the first place ? Kindly throw some light guys....

Format string problem

Hi...

I have a radgridview linked to a datasource.

One of the columns (a decimal column) takes the data from an integer value in the database... this value represents a time, but I can´t change the type in the database.

I want to show the value in a HH:MM:SS format.
To do that in other situations I just set a string.Format this way:
string.format("{0:00}:{1:00}:{2:00}", value/3600, (value%3600)/60,(value%3600)%60)

Is there a way to apply this custom format to the column?

I´ve tried using a date format in the FormatString property of the columm this way: {0:hh.mm.ss} but then the columm shows data like this "hh.Valuemm.ss" (Value is the integer in the column, like 4 or whatever).

Any help will be welcomed

Thanks in advance

GridView FontSize of Q3 2007 SP1

Hi Telerik Team,

I am currently using Q3 2007 SP1. I have poblem with the fontsize of the GridView. I try to change the fontsize through visual style builder (the edit element). It works fine when design. However, on runtime, it prompts me error of index and the fontsize back to as the default.
Please clarify if this problem existed in the version i mentioned.
Thanks in advance
