radGridView1_CustomSorting event not firing

Hey everyone,

Title Correction: radGridView1_CustomGrouping event not firing

I am trying to implement the following example I have found in the Telerik forums to get custom month sorting to work. (Link) I tried setting the CustomDataOperation on the column as the example indicates. When I did that, the Intellisense description stated that the CustomDataOperation property was deprcated and to use EnableCustomGrouping, EnableCustomSorting, etc on the GridView instead.

I have set all of these properties to true, yet the radGridView1_CustomSorting event does not fire.

Why? What else is needed?

For a quick test

But will it work if we build the application (which uses Telerik) with platform target as x64?

Calculated Column Value Issue

Hi All,

I'm having a strange problem which I can't seem to work out the reason for. I have a series of columns of which one is calculated. When I go to save the values (be it a new row or an update), the field which the calculated column is linked with does not get updated.

My code for creating the calculated column is as follows:

GridViewDecimalColumn col = new GridViewDecimalColumn();

col.Name = "Total";

col.HeaderText = "Total";

col.FormatString = "{0:c0}";

col.MaxWidth = 90;

col.MinWidth = 90;

col.Width = 90;

col.FieldName = "Total";

col.FormatInfo = CultureInfo.CreateSpecificCulture("en-GB");

radGridView1.Columns.Add(col);

radGridView1.Columns["Total"].Expression = "IsNull(Ink, 0) + IsNull(PB_Products, 0) + IsNull(Office_Supplies, 0) + IsNull(Freight, 0)";

radGridView1.Columns.Move(11, 9);

For the Save Button, I'm using TableAdapter.Update()

Where abouts have I gone wrong?

Regards,

Guy

Databinding with DataSet

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 -
