So why didn't you tell us your need in the first place. We are no mind readers.
Regarding your actual problem. Search the articles for "file extension" or something similar and you should get what you need.

Like this:
dataGrid1.DataSource = ds.Tables[0].Columns[indexofcolumn];

My task is to fill a DataSet from a data source and update another data source
in C#.
For example I have two databases in SQL Server (i.e. db1 and db2).
I have table named ProdMkt_Contrib_Link in db1 with following columns:
ProdMkt_Contrib_Link
--------------------
ProdMktContributorID (PK)
ProductMarketID
Priority
Inactive
Contrib_Type_Override
ProdMkt_Contrib_Link_ID
The above columns data should be mapped/sync to the table named
ProdMktContribLink in db2:
ProdMktContribLink
------------------
ProdMktContributorID (PK)
ProductMarketID
Priority
InactiveFG
ContribTypeOverRide
AcumenProdMktContribLinkID
Note: The table name and few column name are different
Suppose few records are added and few are updated in the
db1.ProdMkt_Contrib_Link table.
I have filled the typed DataSet (DS1) with db1.ProdMkt_Contrib_Link (this
contains only added and updated records) ans also filled the another DataSet
(DS2) with db2.ProdMktContribLink (this contains all records).
Now I want that DS1 should be sync with the DS2. That is, the added records
should be added to the DS2 table rows and also updated records should be updated
to the DS2 table rows.
How can I achieve this in c#. Please suggest any good design or sample code.
Thanks,
Kamran

or execute the query.

Your statement getsthe query string into the string variable str. The compiler error occurs, because str is declared as an int.
If you want to use LINQ to query the datasource, try this article:
http://www.codeproject.com/useritems/SudokuSolver.asp[^]
Otherwise you have to connect to the database and query it with an SqlCommand:
<br />
using (SqlCommand selectCommand = new SqlCommand("select dashboardid from dashboardlogin where userid=101", connection))<br />
{<br />
object objResult = selectCommand.ExecuteScalar();<br />
if (objResult != null)<br />
{<br />
int str = (int)objResult;<br />
}<br />
}<br />

You got it all wrong.
Please read a database tutorial.
Just a hint. Someone must execute the desired sql command , don't you think?
Its just as you have written
int a="Hello World";
the you just happen to have for text an a sql command.
Read the db tutorial.

nekshan,
your variable str should also be the same type of the column, here your coulmn datatype is int, so declare @str int and try.
Check whether the dashboardid datatype in your table!!!
