As per Prerak K’s update comment (since deleted):
I guess I have not presented the question properly.
Situation is this: I want to load data into a global variable based on the value of a control. I don’t want to change the value of a control from the child thread. I’m not going to do it ever from a child thread.
So only accessing the value so that corresponding data can be fetched from the database.
The solution you want then should look like:
UserContrl1_LOadDataMethod() { string name = ""; if(textbox1.InvokeRequired) { textbox1.Invoke(new MethodInvoker(delegate { name = textbox1.text; })); } if(name == "MyName") { // do whatever } }
Do your serious processing in the separate thread before you attempt to switch back to the control’s thread. For example:
UserContrl1_LOadDataMethod() { if(textbox1.text=="MyName") //<<======Now it wont give exception** { //Load data correspondin to "MyName" //Populate a globale variable List<string> which will be //bound to grid at some later stage if(InvokeRequired) { // after we've done all the processing, this.Invoke(new MethodInvoker(delegate { // load the control with the appropriate data })); return; } } }
