WPF datagrid 行数据字段获取

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;

            }
           
        }
