从WPF中的datagrid表中删除选定的行

问题描述

大家好，

我有一个小查询，

在按钮上单击应从DataGrid表中删除所选行。

以下是我的代码：

On button click the selected row should be deleted from the DataGrid table.
Below is my code:

public partial class
MainWindow ：Window

{

        DataView dv;        


        DataTable dt;

        DataRow dr;

  Public MainWindow（）

 Public MainWindow()

  {

 {

             InitializeComponent（）;

            this.SizeToContent = SizeToContent.WidthAndHeight;

            DataTable dt1 = new DataTable（）;

            dt1.Columns.Add（ " ListOfPhases" ）;

            dt1.Columns.Add（ " PhaseCount" ）;

            dt1.Columns.Add（ " S_no1" ）;

            DataRow dr = dt1.NewRow（）;

            dgvListOfPhasesAndCount.ItemsSource = dt1.DefaultView;

                     {

                        iNumber ++;

                        dr [ " ListOfPhases" ]
= cbInBuildList.SelectedItem.ToString（）;

的" ListOfPhases" 的]。ToString（））;

的                         dr [ " PhaseCount" ]
= tbEnterCountValue.Text;

的" PhaseCount" 的]。ToString（））;

的                         dr [ " S_no1" ]
= iNumber;

               &NBSP ;        dt.Rows.Add（dr）;

                    }

                }

                

            }

            catch（NullReferenceException）

            {

            }

 }

私人无效Button_DeleteSelectedRow_Click（对象发件人，RoutedEventArgs E）

 Private void Button_DeleteSelectedRow_Click(object sender, RoutedEventArgs e)

  {

     
//需要代码

    //Need code here

  }

 }

}

任何人都可以帮助我完成这个过程。

Can anyone kindly help me through this process.

提前感谢。
