Delegates And Cross Thread Exception
- by Neo
Whenever i am updating UI in windows form using delegate it gives me cross thread exception
why it is happening like this?
is there new thread started for each delegate call ?
void Port_DataReceived(object sender, SerialDataReceivedEventArgs e)
{
//this call delegate to display data
clsConnect(statusMsg);
}
protected void displayResponse(string resp)
{
//here cross thread exception occur if directly set to lblMsgResp.Text="Test";
if (lblMsgResp.InvokeRequired)
{
lblMsgResp.Invoke(new MethodInvoker(delegate { lblMsgResp.Text = resp; }));
}
}
