Hi.

I have this:

GridViewSummaryItem Duracao = new GridViewSummaryItem();
Duracao.Name = "Duração";
Duracao.FormatString = "{0}";
Duracao.AggregateExpression = "(sum(T_H))";

sum(T_H) it's the sum of times in seconds. I need show the result in time format (hh:mm:ss)

How i can do it? help please.

i'm program in C#.

Thank you.

As the title suggest, how can I deselect currently selected row if it's previously selected? I have MultiSelect set to False. Ctrl + click doesn't work.

I have a RadAutoCompleteBox working as expected allowing user to type and pick an item from the list.

The token is then shown in the Textbox as expected.

Would like to have a way when they type again and pick another item, to then remove the 1st and only show the 2nd item.

Tried the  radautocompletebox.Text = "" but received some error.  It would be nice to have a property stating (Multiple Tokens (true/false).

Maybe there is a programmatically way to click the X in the token to remove it before adding the 2nd token?

Hello,

I am working an application where I need to open the different application forms in the same main window; in other words, I have created a dashboard where it contains a several buttons, each of them should open a specific form for example, The Employees, Products, Tasks, and etc. when I click on each of the buttons, It should show the other forms but in the same RAD form.

Form.TopLevel = False property isn't working so, How can I do it?

My project is a VB.NET 2019.

Thanks in advance for your continues assistance and cooperation,

Hi.

After a date is picked I want to delete it and set the value to null on the data bound item.

The NullableValue is set to null/Nothing:

 Me.DateRadDateTimePicker.NullableValue = Nothing

The Value property is bound to an entity's nullable date field:

 Me.DateRadDateTimePicker.DataBindings.Add(New System.Windows.Forms.Binding("Value", Me.binder, "Date", True))

If I select the date text and delete it, the entity still has a 01/01/0001 date value. However, the null text correctly displays in the picker.

I've even tried to manually set the null date (in three different ways!) based on the empty text but to no avail:

Dim dtp As RadDateTimePicker = ctrl
If dtp.Text = "" Then
  dtp.NullableValue = Nothing
  dtp.DateTimePickerElement.SetToNullValue()
  dtp.Value = Nothing
End If

What am I missing?
