gridControl 单元格换行的问题

Question

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!!??

Answer 1

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。C#]
 using System;
 using System.Drawing;
 using System.Windows.Forms;
 using System.Data;
 using System.ComponentModel;
 
 namespace Dobon.Samples.Forms
 {
     /// <summary>
     ///为了在DataGrid上表示改行字符串的DataGridColumnStyle
     /// </summary>
     public class DataGridTextBoxColumnEx : DataGridTextBoxColumn
     {
         //指定描绘文字列的Margin
         Point _margin = new Point(1, 2);
 
         //TypeConverter取得
         private TypeConverter _typeConverter = null; 
         public override PropertyDescriptor PropertyDescriptor
         {
             set
             {
                 base.PropertyDescriptor = value;
                 if (PropertyDescriptor != null &&
                     PropertyDescriptor.PropertyType != typeof(object))
                 {
                     _typeConverter =
                         System.ComponentModel.TypeDescriptor.GetConverter(
                         PropertyDescriptor.PropertyType);
                 }
             }
         }

             string text =
                 GetText(GetColumnValueAtRow(source, rowNum));

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

Answer 2

gridControl.DataSource=ds;
gridControl.DataMember=ds.Tables[0].TableName;
DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit x=new DevExpress.XtraEditors.Repository.RepositoryItemMemoEdit();
gridView1.Columns[1].ColumnEdit=x;
gridView1.Columns[1].FiledName="内容";//绑定的字段
gridView1.Columns[1].Width=100;
gridView1.OptionsView.RowAutoHeight=true;
