c# - sync data grid view -

i have data grid view data source data table in form in c#, how can make read table database continuously mean if program running in many computers in same network , connected same database , if computer 1 add row database appears automatically in computer 2 without clicking button refresh.

void load()     {         c.connect("sel_dep");         c.com.commandtype = commandtype.storedprocedure;          sqldataadapter da=new sqldataadapter (c.com);         datatable dt = new datatable();         c.open();         int last = 0;         while (true)         {             if (dt.rows.count > 0)                 dt.rows.clear();             da.fill(dt);             dd = dt;             if (dt.rows.count != last)             {                 last = dt.rows.count;                 this.invoke((methodinvoker)delegate { datagridview1.datasource = dt; datagridview1.selectedrows[0].selected = true; label1.text = datagridview1.rowcount.tostring(); });             }         }         c.close();      }     private void form3_load(object sender, eventargs e)     {         aa = new thread(() => { load(); });         aa.start();        }

if using winforms create desktop application, not need timer.

simply drag , drop timer control toolbox on form, in design mode.

' form load should altered below private void form3_load(object sender, eventargs e) {     ' assume timer control named 'otimer'     otimer.enabled = true;     otimer.interval = 60000;    ' in milliseconds, equates 1 minute     otimer.start(); } 

create tick event timer. event fired each time interval elapses.

private void otimer_tick(object sender, eventargs e) {     <call function initiate/refresh datagrid.datasource within event> } 

in order further understand how timer class works, refer timer class (system.windows.forms).
