Hello..........

i am working on C# Windows From Developemnt.i want to add automatically primary key value in Master and Detail Form.
Please give me idea about this.





Continusous work with commitment lead towards a new creation

Primary Keys are set on the DataTable of the data. Simply get the column and set the .Unique property as true;


//This sets a single column

DataTable dt = new DataTable();
DataColumn dc = new DataColumn("Id");
dc.Unique = true;

dt.Columns.Add(dc);

//This sets several columns

DataTable dt = new DataTable();
DataColumn dc1 = new DataColumn("Id1");
DataColumn dc2 = new DataColumn("Id2");

dt.Columns.Add( dc1);
dt.Columns.Add( dc2);

dt.PrimaryKey = new DataColumn[] {dc1, dc2};

Regards,

Dom
