Door library (Beta) - Special library

[berndgoedecke]

Hello Erol,
What I need at first is an answer to the question in the title.
I try to show the table only with a horizontal ScrollBar, similar to the example from agrahm:
Horizontal Scroll Bars

AddTable ("TabGrid", "TG", 0, 0, FW, FH-(12*Hs))
TOb.New1(True)
TOb.FromControl("TG")
TOb.SetProperty("ScrollBars","Horizontal")
TabGrid.show

The line, TOb.SetProperty("ScrollBars","Horizontal") results in an error like
Objectreference is not fixed in an objectintance (translated from german).
I think, this error is in context with the last line of your object dicription:
System_NS, System_Data, System_Drawing, System_Windows_Forms, System_Windows_Forms_Datagrid - Returns the fully qualified named (do you mean names?(d-key next s-key)) of these assemblies. System_Windows_Forms_Datagrid will only be set if at least one of the objects was initialized with New1(true).
If so, it would be nice to know how to use.

In the future I want to use features to reorder columns, to get the row height and to autosize columns, rows or cells, if this is possible.

Best regards

As you can see in the MSDN documentation, the DataGrid doesn't include a ScrollBar property.

Adding additional events to controls is now supported. Each type of event provides access to an EventArgs which contains information about the event. I've taken Erel's first post and used it as the basis for a sort of help file and included an indication of the information in each type of EventArgs. To find out more detail I would suggest Googling for the name of the EventArgs you are interested in.

Thanks agraham

As an example of the power of this library (and of .NET) I have created this example application which can "look inside" controls (this is called reflection in .NET-speak) and show the properties, events and methods they support.

Enter the type of a control (it is case-sensitive so "TextBox" not "Textbox") in the textbox and press Enter. Select the type of members to display and click on items in the list box for information about it. Events will show the type of EventHandler they use which should be one of those listed by Erel in the first post if they are to be used by this library.

Some B4PPC control names are not the same as their .NET names. A B4PPC Image is PictureBox, Menu is MenuItem, NumUpDown is NumericUpDown, RadioBtn is RadioButton, Table is DataGrid.

Calendar and ImageButton are custom controls based on the Control type.

Hello Agraham,
if I use your program with DataGrid on the Device the error Message: "Please enter a valid .NET control name" apears. Framework2.0 is installed and programs , using Tablecontrol are working. How could it be ? Is there an Framwork SP missing?

Best Regards

I now realise the significance of the System_Windows_Forms_Datagrid property of the Door library. On the desktop DataGrid lives in the System_Windows_Forms assembly, on the device it lives in the System_Windows_Forms_Datagrid assembly.

A crudely modified version of ControlInfo is attached which will show you DataGrid on the device. More elegantly it now shows all the signatures for overloaded mathods.

Hi. Could this library be possibl ported down to the .NET framework 1.1 and .NET CF 1.0? Thanks.

[Erel]

It uses several methods which are not available in .Net CF 1.0.
