I am new at C#, I have a WPF, and a GridControl. I want users be able to import their own datas from their own excel files. How can i do that?

I started to learn c# this week, i tried sth from the net but it didn't work

I downloaded DevExpress, and i added a DataControl to my WPF. I clicked "Create Data Source" and it gave those options

ADO.NET Data Set
Entity Framework
Linq to SQL
WCF Data Services
IList/IE Numerable...

I guess this way i can import some data from a excel from my computer. But i want every users can choose their own excel files. So i guess i needed an address bar kind of thing.

I want to create a WPF form. Users can create their own matrix tables.(For example one of them needed 3*7 matrix- user will make this choice) or ( I want WPF have "Add Row" and "Add Columns" button, and by using them Rows and Columns will be added)

How can i do that?

Can i create a table in WPF and let users set the column and row number? How?

says ".... have some invalid arguments"

No but,mw2.Owner = this; solved!

mw2.Owner = this; solved! Thanks

"does not contain a definition for TopMost " gives this error

How can i do that?

I wrote like this but didnt work.

else
{
mw2.ShowDialog();
mw2.Activate();
}
}
}

Thank you but;
-------------
WPF1.Show();
this.Close();
-------------
Also worked. But there is another problem. When i open the WPF by button. It
is opened behind the WPF which is exist. So i can't see that. How can i take the
new WPF to the front?

How can i do that?

I have a "enter" window and it has a button "enter". when i click it,
antoher window(mw1)
is opened.

And that time i want the "enter" window" closed.

Is it too hard?, I have an homework. A form can perform matrix multipication. Will it be too hard?

It worked!, Thanks. Sorry, i started to learn c# this week and i couldn't find a good source.

How can i add it?

says..."Could not be found" .In the project folder. Those two
in different folders. Can it be because of that?

Yes it is in DXWPFApplication3. I dropped. Still not working.

When I tried
----------
using DXWPFApplication3;
----------
says "could not be found".....

I accept the code but doesn't accept the namespace...(says" identifier expected,namespace is a keyword)...How do i identify it?

I added the code.

Nope, it didnt work. underlined "DXWPFApplication3;"

I wrote this:
---------------------------------------------
using Namespace_that_MainWindow_2_Resides_In;
---------------------------------------------

But it didn't accept it. I tried this then;
-----------------------------------
using namespace.DXWPFApplication3;
-----------------------------------

Now VS accepts the MainWindow_2(Remove the red underlines), but now doesn't
accept "namespace" word in the using place. Says "identifier expected, namespace is a keyword".

What should i do?
Thank you very much.

It didn't work

I am new at C#, could you tell me have to do that

Thanks.(It's in the same assembly)

VS underlines "MainWindow_2" and says "Namespace or Type couldn't be found"
But my second forms have that name:
----------------------------------------------------
public partial class MainWindow_2 : DXRibbonWindow
----------------------------------------------------

What's the problem?

Or can you just tell me the codes,for a button to open a new form.

x:Class="DXWPFApplication3.MainWindow_2" i changed the name like this. But didn't solved.

I looked but, all i found is a code which add the column in the end of DataTable.

I want the colmuns be added after 3.column. How can i do that?

Thanks

I couldn't find, can you give the link?
Thanks

I mean windows app forms

I just wanted to pointed out the problem which is this; any XXXXX.cs project can't be debugged. And how can i run any project without .sln file of the project. By the way, thank you for your concern.

Thanks

How can i run the .cs projects?

What should i do?

No its not my screenshot i just have the same problem. When i copy the codes and paste to a "new project", debug option is available but, whenever i open an another project, its off again. why?

You didn't understand. That's not mine. I just have that problem. Debug option is
not available.

it's like in that picture.
