I am the whole DGV table cell background color is stored, the color of each cell is different, save, and then read the assignment to DGV form cell,
Speed is too slow, a DGV form will be more than 3 seconds, is there a way to save and read quickly?

CodePudding user response:

Datagridview background color can be stored in XML, as long as open a program, will load the background color, by rows and columns, and color, then the binding datagridview, then change color line directly

As long as you bind data do not refresh will not disappear!
DataGridView1. The DataSource=dt;
Such as the dataGridView1. The DataSource did not rebound would not be refreshed

Thank you for your answer, don't know how to give to you, hope I can appreciate your guidance,
The binding you said I know, I the problem now is that my data is more, the color is more complex, this binding approach speed is slow, is there a better way, bulk binding background color,
Is not only the increase speed to get out of the way
