[C#]fill a datagridview from a secondary thread

[akshaycjoshi]

I have one datagridview which i fill using the connected verion of ADO.NET.
When the user presses the search button a seperate thread is created and in that thead i connect to the database and fill the datagridview.

        private void cmdsearch_Click(object sender, EventArgs e)
        {
            ThreadStart t = fillthegrid;
            Thread fillthread = new Thread(t);
            fillthread.Start();
        }
        
        void fillthegrid()
        {
            //do some stuff like disabling the search button to avoid repetitive calls
            //here I connect to the database and show it in datagridview
            //enabling the search button again
        }

In the fillthegrid() I will have acces the button.enable property and access the the rows for writing but since the thread is not the primary I cant access it.
How to get around this problem ?

Thanks !

Create a new Thread class whose constructor takes a grid and use that.

And what about the button ?
Also, since the thread is the not the one which created the Grid will I be able to access it is suspecious.

If your thread takes a grid as argument then it doesn't matter who created it. The thread should be able to work on that grid just fine.
A similar approach should suffice for the button. If the thread needs to update many more controls though then a different approach would be required.

Please explain that method by an example as I need to update many controls from a secondary thread.

bump ! (to get it on top again)

If you need to update many controls then make that thread an inner class in the class that has those controls.
