问题描述

        this.dataGrid1 = new System.Windows.Forms.DataGrid();
        this.dataGrid1.DataMember = textBox1.Text.ToString();
        this.dataGrid1.Location = new System.Drawing.Point(36, 46);
        this.dataGrid1.Name = "dataGrid1";
        this.dataGrid1.Size = new System.Drawing.Size(364, 532);
        this.dataGrid1.TabIndex = 0;
        //
        this.AutoScaleBaseSize = new System.Drawing.Size(50, 13);
        this.ClientSize = new System.Drawing.Size(592, 573);
        this.Controls.AddRange(new System.Windows.Forms.Control[] { this.dataGrid1 });
        ((System.ComponentModel.ISupportInitialize)(this.dataGrid1)).EndInit();
        this.ResumeLayout(false);


        XmlDataDocument xmlDatadoc = new XmlDataDocument();
        xmlDatadoc.DataSet.ReadXml("abcd.xml");

        DataSet ds = new DataSet("abc");
        ds = xmlDatadoc.DataSet;

        dataGrid1.DataSource = ds.DefaultViewManager;

这是显示了分层结构，但它不是子和父节点区分properly.i只想看看这应该是其子node.also链接根节点，我想数据网格要能够编辑XML文件。

It is showing the hierarchial structure but it is not distinguishing between the child and parent node properly.i only want to see the root node which should be a link to its child node.also,i want the datagrid to be able to edit the xml file.

推荐答案

阅读DataSet中的Xml你为什么不设置数据表，而不是整个数据集作为网格的数据源后？

After reading the Xml in DataSet why dont you set the DataTable rather than the whole DataSet as DataSource of the Grid ?

    XmlDataDocument xmlDatadoc = new XmlDataDocument();
    xmlDatadoc.DataSet.ReadXml("abcd.xml");

    DataSet ds = new DataSet("abc");
    ds = xmlDatadoc.DataSet;

    dataGrid1.DataSource = ds.Tables[0];

调整与相应的根表的表索引。

Adjust the Table index with your appropriate Root table.
