Hi saifullahiit

step1:
take database connection and create command for selecting the values like(select * from employee--this will give all the values of employee)

step2:
use any databound contorl(gird or datalist or list view or repeter) then bind that data to that contorl

like this:

need to add namespace:
Using System.Data.Sqlclient;

SqlConnection con=new SqlConnecton("give here your connection string");
SqlCommand cmd=new SqlCommand("give your query here");
Dataset ds=cmd.ExecuteReader();
if(ds.tables.count>0)
{
if(ds.tables[0].rows.count>0)
{
grid1.Datasource=ds.tables[0];
grid1.databind();
}
}

like this you need to do,if you have any doubts,let me know

thanks
