This is very good and working fine but I have a small problem with the below code.

dataGridView1[col + i, row].Value =

Convert.ChangeType(cells[i], dataGridView1[col + i, row].ValueType);

If the type of column is nullable i.e., decimal? or byte? then valuetype returns “Nullable” type but not the underlying decimal or byte which is resulting in exceptions. Is there any work around for nullable fields?

I encapsulated the code for dragging and dropping between DataGridView’s into a control. I saw a lot of code, but no control that was pre-built.

It is available at…

I think you can continue to hold CTRL when you drag.

I am unsure because in my use case I have multiselect disabled for to DGV

This works great except I have one problem. If select multiple rows and then click the selection to drag the rows to their destination. The MouseDown event has been processed and the only row that is selected is the row I clicked to drag. Is there a way to suppress the MouseDown event from selecting the clicked row when I want to drag the selection?
