Hi All,

I am binding combobox at runtime with table named tblcty (which has records) but not showing in combobox.

SqlDataAdapter adp = new SqlDataAdapter("Select * from tblcty", con);
DataSet ds = new DataSet();
adp.Fill(ds);
cbfrom.DataSource = ds.Tables["tblcty"];
cbfrom.DisplayMember= "CtyName";
cbfrom.ValueMember = "CtyID";

Regards!
Aman

Try these.It may help

1.Check if ds is empty or not.
2.try ds.Tables[0]; instead of ds.Tables["tblcty"];
3.Check DisplayMember name & Valuemember name is the same column name in dataset.

Solution 1

See your code here.

MIDL

adp.Fill(ds);
cbfrom.DataSource = ds.Tables["tblcty"];

dataset is not setting table name itself based on table name in db you're retrieving.

You need to define it explicitly, In other way if you aren't defining it then you simply fetch table from dataset using indexing.

So Update your snippet with.

MIDL

adp.Fill(ds);
cbfrom.DataSource = ds.Tables[0];

OR

MIDL

adp.Fill(ds,"tblcty");
cbfrom.DataSource = ds.Tables["tblcty"];

Hope it helps.
