本文介绍了在WPF中如何从Datagrid中获取选中行的数据，包括公司ID和公司名称。提供了两种方法实现，一种直接针对DataRowView，另一种适用于自定义数据模型。当使用自定义的CompanyInfoModel时，通过属性访问器获取选中行的CompanyID和CompanyName。

方法一:

private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

if (dataGrid1.SelectedIndex != -1)
{

this.textBox1.Text=(e.AddedItems[0] as DataRowView).Row["CompanyID"].ToString();
this.textBox2.Text=(e.AddedItems[0] as DataRowView).Row["CompanyName"].ToString();

}

方法二:

private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

if (dataGrid1.SelectedIndex != -1)
{

this.textBox1.Text =(dataGrid1.SelectedItem as DataRowView).Row["CompanyID"].ToString();
this.textBox2.Text = (dataGrid1.SelectedItem as DataRowView).Row["CompanyName"].ToString();

}

红色部分表示dataGrid1绑定的数据模型.

如果是自定义的数据模型,那么应该做相应的修改.举例:

自定义绑定数据模型:

public class CompanyInfoModel
    {
        /// <summary>
        /// 返回两个字段
        /// </summary>
        ///
        #region properties
        public string CompanyID { get; set; }
        public string CompanyName { get; set; }
        #endregion

        public static CompanyInfoModel CreateNewCompanyInfoModel()
        {
            return new CompanyInfoModel();
        }
        public static CompanyInfoModel CreateCompanyInfoModel(string companyid,string companyname)
        {
            return new CompanyInfoModel { CompanyID = companyid, CompanyName = companyname };
        }
        public CompanyInfoModel()
        {

        }
    }

....省略绑定过程....

    private void GetDataFromDataProvider()
        {
            _companyInfoDataProvider = new CompanyInfoDataProvider();
            this.AllCompanyInfo = new ObservableCollection<GMMIS.Model.CompanyInfoModel>            (_companyInfoDataProvider.GetCompanyInfoData());
        }

....省略绑定过程....

那么,最终,dataGrid单击数据行后,返回数据的方法如下:

private void dataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
             if (dataGrid1.SelectedIndex != -1)
            {
                this.textBox1.Text = (e.AddedItems[0] as Model.CompanyInfoModel).CompanyID;
               this.textBox2.Text = (e.AddedItems[0] as Model.CompanyInfoModel).CompanyName;

            }

        }
