c# - Displaying data on a datagrid too slow -

-

I have the DataGrade (WPF / C #), which is pulling from a large field into two fields. However, It takes a very long time to render on the screen and I want to know that there is a fast way? 

  Private Zero SetupDataGrid () {try {_con.Open ()} Var com = New MySqlCommand ("Select Record ID", `TLBTist by Company Name`; all)" { Connection = _con, commandtip = commandtip.text}; var dt = new dataTable (); var sdt = new MySqlDataAdapter (com); sdt.Fill (DT); DataGrade activitivity.datcontext = dt;} hold (exception before) {message Show the box (ex.ToString ());} _con.Close (); You can apply paging in the grid, and only remove the records from the database. Another way would be to remove data, cache, and then access the cache - but in this case it will slow down for the first time.  
 If there is a problem removing large data sets , Then I can only remove items for the current page.  
 With MySQL you can do this in the following approach  
  SELECT * FROM [TABLE] LIMIT 5,10;

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
