5.45 How can I change the width of the row headers or hide them?

You can get at the width and visibility of the header row/column through a DataGridTableStyle. DataGridTableStyle has properties such as RowHeadersVisible and RowHeadersWidth. DataGridTableStyle also controls things like selections colors and GridLine styles.

// Create a table style that will hold the new column style

// that we set and also tie it to our customer's table from our DB

DataGridTableStyle tableStyle = new DataGridTableStyle();

tableStyle.MappingName = "customers";

//hide the column headers

tableStyle.ColumnHeadersVisible = false;

//change width of the row headers

tableStyle.RowHeadersWidth = 100;

// make the dataGrid use our new tablestyle and bind it to our table

dataGrid1.TableStyles.Clear();

dataGrid1.TableStyles.Add(tableStyle);
