我是使用DevExpress的新手。我需要设计并绑定一个复杂的DataGrid。
我是使用Designer设计的。数据网格类型为Master-Detail,它包含“MainGrid”和其他详细网格。其中一个是类型:'advBandedGridView'
MainGrid的设计如下所示:
'advBandedGridView'的设计如下:
现在,我需要使用Lists集合填充我的DataGrid,因此我使用了以下代码:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Collections;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void simpleButton1_Click(object sender, EventArgs e)
{
ArrayList a = new ArrayList();
Term_Space_Grid t = new Term_Space_Grid("x", "y", true, "z");
t.expansions = new List<MyExpansions>();
t.expansions.Add(new MyExpansions(0, "Aya", 0, 0, 0, 0, 0));
a.Add(t);
resultsGridControl.DataSource = a;
}
}
public class Term_Space_Grid
{
public string x { get; set; }
public string y { get; set; }
public string g { get; set; }
public bool z { get; set; }
public List<MyExpansions> expansions { get; set; }
public Term_Space_Grid(string x, string y, bool z, string g)
{
this.x = x;
this.y = y;
this.z = z;
this.g = g;
}
}
public class MyExpansions
{
public Morphos morphos { get; set; }
public Semantics semantics { get; set; }
public MyExpansions(int morphoID, string morphoDerivation, int synID, int subID, int supID, int hasID, int insID)
{
this.morphos = new Morphos(morphoID, morphoDerivation);
this.semantics = new Semantics(synID, subID, supID, hasID, insID);
}
}
public class Morphos
{
//public List<Morph> morph{ get; set; }
public Morph morph { get; set; }
public Morphos(int morphoID, string morphoDerivation)
{
//this.morph = new List<Morph>();
//this.morph.Add(new Morph(morphoID, morphoDerivation));
this.morph = new Morph(morphoID, morphoDerivation);
}
}
public class Semantics
{
public List<Sem> synonyms { get; set; }
public List<Sem> subClasses { get; set; }
public List<Sem> superClasses { get; set; }
public List<Sem> hasInstances { get; set; }
public List<Sem> instanceOf { get; set; }
public Semantics(int id1,int id2, int id3, int id4, int id5 )
{
this.synonyms = new List<Sem>();
this.subClasses = new List<Sem>();
this.superClasses = new List<Sem>();
this.hasInstances = new List<Sem>();
this.instanceOf = new List<Sem>();
this.synonyms.Add(new Sem(id1));
this.subClasses.Add(new Sem(id2));
this.superClasses.Add(new Sem(id3));
this.hasInstances.Add(new Sem(id4));
this.instanceOf.Add(new Sem(id5));
}
}
public class Morph
{
public int MorphoID { get; set; }
public string MorphoDerivation { get; set; }
public Morph(int morphoID, string morphoDerivation)
{
this.MorphoID = morphoID;
this.MorphoDerivation = morphoDerivation;
}
}
public class Sem
{
public int SemID { get; set; }
//public string MorphoDerivation { get; set; }
public Sem(int semID)
{
this.SemID = semID;
}
}
}
但是,我发现结果是作为一个没有任何设计形式的新DataGrid构建的。我的意思是我在Designer中定义的细节选项卡没有出现在结果网格中。
结果如下:

首先,您应该通过GridColumn.FildName属性在数据对象属性和GridView列之间创建关联。
对于您的主视图(gridView2
),它看起来像这样:
// gridColumn1
this.gridColumn1.Caption = "ID";
this.gridColumn1.FieldName = "x"; // associate this column with Term_Space_Grid.x property
this.gridColumn1.Name = "gridColumn1";
请阅读以下文章了解更多详情:Creating Columns and Binding Them to Data Fields
其次,您不能直接将列绑定到对象的嵌套属性(例如,MyExpansions.semantics.subclasses.SemID
)。
要绕过此限制,您可以使用以下几种方法:
第三,要获得正式且有保证的答案,您应该直接向DevExpress Support Center解决与任何DevExpress产品相关的紧急问题。
