DataGridView Selection

When data is added or searched in a DataGridView, it make it easier for the user to programmatically
change the DataGridView selection.

Set DataGridView Selection

Here's how to set the active row of a DataGridView. The two example variables will be dataGrid, which is
a DataGridView, and index, which is the index of the row you want to select with C# code.

First is to scroll down the DataGridView so the row is visible in the screen:

dataGridView1.FirstDisplayedScrollingRowIndex = index; dataGridView1.Refresh();

Then you must select the row so that binding sources update their Current item:

dataGridView1.CurrentCell = dataGrid.Rows[index].Cells[0];

Finally, you can visually select the row with C#:

dataGridView1.Rows[index].Selected = true;


The C# code above assumes that you are trying to select an entire DataGridView row. However it is simple
to adjust if you just want to select a Cell. Otherwise the code will work to set the DataGridView selection.
