gridControl 单元格换行的问题
找了半天不知道在哪设置!!就是数据满行后自动换下一行显示!!怎么设置!!?? --------------------编程问答-------------------- gridcontrol// 不知道是什么控件,不过帮顶一下. --------------------编程问答-------------------- DataGrid控件的单元格内文字列的换行表示，可以通过作成DataGridColumnStyle类的派生类，重载Paint方法描绘文字列实现。
下面的例子是继承DataGridTextBoxColumn类作成新类（DataGridTextBoxColumnEx）。
补充：如果使用VB.NET时，需要PropertyDescriptor可以把C#代码生成DLL然后引用。

this.dataGridView1.RowsDefaultCellStyle.WrapMode = DataGridViewTriState.True;//换行
this.dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCells;//自动行高
foreach (DataGridViewColumn c in this.dataGridView1.Columns)
c.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCellsExceptHeader;//行动列宽
