I use Devexpress GridControl. And I want to change cell value according to tcp messages.
private void Form1_Load(object sender, EventArgs e)
{
grid_mygrid.DataSource = Get_Devices_Info.Get_Device_From_DB().Tables[0];
this.tcpListener = new TcpListener(IPAddress.Any, 2000);
this.listenThread = new Thread(new ThreadStart(ListenForClients));
this.listenThread.Priority = ThreadPriority.Highest;
this.listenThread.Start();
}
private void ListenForClients()
{
this.tcpListener.Start();
while (true)
{
TcpClient client = this.tcpListener.AcceptTcpClient();
Thread clientThread = new Thread(new ParameterizedThreadStart(HandleClientComm));
clientThread.Start(client);
}
}
private void HandleClientComm(object client)
{
...
try
{
gridView1.SetRowCellValue(row_index, "boot_progress", 50);
}
catch(Exception e)
{
if (e.InnerException != null)
{
Log2LogText(e.InnerException.Message);
}
}
...
}
if I want to try this under the thread
gridView1.SetRowCellValue(row_index, "boot_progress", 50);
if row_index=0 -> It is OK
if row_index>0 -> An unhandled exception of type 'System.Reflection.TargetInvocationException' occurred in mscorlib.dll
About GridControl if i try this with button click
gridView1.SetRowCellValue(1, "boot_progress", 50); -> It is OK
gridView1.SetRowCellValue(2, "boot_progress", 50); -> It is OK
gridView1.SetRowCellValue(4, "boot_progress", 50); -> There is no row with index 4. But there is no error. It is OK.
gridView1.SetRowCellValue(5, "random_column", 50); -> There is no column with "random_column". But there is no error. It is OK.
I use try-catch but this code still give an error and program stop. When I comment this line
gridView1.SetRowCellValue(row_index, "boot_progress", 50);
there is no problem
I'm waiting for your suggestions.
