Solution 1

use the dropdown's SelectedIndexChanged event to load the table of interest in a DataTable, then bind that to your DataGrid.

protected void ddlUsers_SelectedIndexChanged(object sender, EventArgs e)
{
string strQuery;
string userName = ddlUsers.SelectedItem.Text;
if(userName=="All")
strQuery = "SELECT .....";
else
strQuery = "SELECT .....Where SCEUD.UserId='" + userName + "'";
DataSet dsHistory = ExecStatements(strQuery);
//here I am using the list box ... ur code goes here
lstHistory.DataSource = dsHistory;
lstHistory.DataTextField = "url";
lstHistory.DataBind();
}

protected DataSet ExecStatements(string sqlCmd)
{
SqlConnection sqlConn = new SqlConnection(strConnection);
SqlCommand sqlComm = new SqlCommand(sqlCmd, sqlConn);
SqlDataAdapter sqa = new SqlDataAdapter(sqlComm);
DataSet ds = new DataSet();
sqlConn.Open();
sqa.Fill(ds);
sqlConn.Close();
return ds;
}
