Hi Bruce,
Thanks for reply.
I did the search for C# UML as well before posting but that didn't give
links where I can find UML diagram for "c# api" you know. I am not
really looking for UML generation or design features in IDE, I am
looking for diagram of the system api itself :(
But I get what you are saying, it will take time to get used to this
MSDN stuff.
I will keep looking.
Now as we are on this thread, I would ask one more question, actually I
am trying to develop Windows Forms application (not Web.UI stuff), and
I wanted to put LinkLabel in the DataColumn of DataGrid but I am not
able to do so. I got this below link where the guy extended
DataGridColumnS tyle to have combobox but I can't figure out how to put
LinkLabel instead of combobox used there.
http://www.c-sharpcorner.com/winform...ataGridSKJ.asp
The issue with that example code is I have to setup too many things to
run it as its using Sql. I appreciate his sharing but I wish he would
have done it more simplistically to show an example rather than having
those sql things in there.
I copied his code and all and tried to understand by putting Enum
object in combobox but all in vein...though I now understand those
DataSet and all upto some extent. So at the end I decided to extend the
DataGridColumnS tyle to put LinkLabel and copied Paint method from his
code and have mixed things right now. Here is the code which is not
working, :)
namespace TestUIApplicati on
{
public class LinkColumn:Data GridColumnStyle
{
int xMargin = 5;
int yMargin = 5;
private LinkLabel linkLabel;
//
// Create a new column - DisplayMember, ValueMember passed by string
//
public LinkColumn(Link Label linkLabel)
{
this.linkLabel = linkLabel;

break;
}
Format.FormatFl ags =Format.FormatF lags;

g.FillRectangle (BackBrush, Rect);
Rect.Offset(0, yMargin);
Rect.Height -= yMargin;

Format.Dispose( );

DataGridLineSty le.Solid)
{
return 1;
}

}
}
}
}
}
And here is the method that loads things,
private void Form1_Load(obje ct sender, System.EventArg s e)
{
listBox1.DataSo urce = this.coloursCol lection;
DataSet ds = new DataSet("Colour sSet");
DataTable dt = ds.Tables.Add(" ColoursTable");
dt.Columns.Add( "ColoursColumn" ,typeof(LinkLab el));
LinkLabel ll = new LinkLabel();
ll.Name = "maulin";
ll.Text ="Maulin";
DataRow dr = dt.NewRow();
dr["ColoursCol umn"] = ll;
dt.Rows.Add(dr) ;
GridTableStyle = new DataGridTableSt yle();
GridTableStyle. MappingName = "ColoursSet ";
GridTableStyle. GridColumnStyle s.Add(new LinkColumn(ll)) ;
GridTableStyle. GridColumnStyle s[0].MappingName =
"ColoursTab le";//EDIT ME
GridTableStyle. GridColumnStyle s[0].HeaderText = "test";
GridTableStyle. GridColumnStyle s[0].Alignment =
HorizontalAlign ment.Left;
GridTableStyle. GridColumnStyle s[0].Width = 700;
GridTableStyle. GridColumnStyle s[0].NullText = string.Empty;
dataGrid1.DataS ource = ds;
dataGrid1.DataM ember = "ColoursTab le";
dataGrid1.Table Styles.Add(Grid TableStyle);
}
Please ignore my table,column names and all , its all the code after
much playing around so far and names might not make sense...
Do you have any idea how to do this? If you wish I can repost this same
thing so it appears in people's search as it would be in appropriate
thread...otherw ise somebody might just go into abysmal I am in...:)
Thanks ton for helping.
Regards,
Maulin

I typed "C# UML diagram" into Google and came up with a bunch of
hits.
As well, VS2005 is coming with a bunch of code refactoring and code
design features in it, including (correct me if I'm wrong), UML-to-C#
and C#-to-UML features.
When I moved from Java to C#, it too cost me time and a bit of
frustration getting my head around the MSDN documentation format.
It's now second nature to read the stuff and figure out how to do things.
The only thing I miss is knowing--for sure--which exceptions the
various methods and properties throw. :(
