问题描述

hi如何从GridView中删除记录，而不是从数据库中删除记录? 这是我的代码.

 DataTable dt = 新 DataTable();
        如果(grdCart.Rows.Count <  =  1 )
        {
            e.Cancel =  true ;
            Response.Write(" )；
        }
        其他
        {
            如果(grdCart.SelectedIndex >  =  0 )
            {
                dt.Rows.RemoveAt(grdCart.SelectedIndex);
                e.Cancel =  false ;
                grdCart.DataSource = dt;
                grdCart.DataBind();
                grdCart.Visible =  true ;
            }
        } 

解决方案

1.您可以使用数据集和数据表来获取结果.

2，您可以在表格中有一个标志"字段，并在单击按钮时设置标志.

或，请尝试以下方式:
将数据库中的数据绑定到"dbTable"之类的数据表.使用dbTable绑定gridview.

在gridview_rowDeleting上...编写以下代码...

 dbTable.Rows [e.RowIndex] .Delete();

Gridview.DataSource = dbTable;

GridView.DataBind(); 

有 [DataTable dt =new DataTable(); if (grdCart.Rows.Count <=1) { e.Cancel = true; Response.Write("You Must Keep One record"); } else { if (grdCart.SelectedIndex >= 0) { dt.Rows.RemoveAt(grdCart.SelectedIndex); e.Cancel = false; grdCart.DataSource =dt; grdCart.DataBind(); grdCart.Visible = true; } }

解决方案

1. u can use a dataset and datatable to get the result.

2, u can have a "flag" field in the table and set the flag when u click the buttons.

or , try in the following way:
bind the data from database to a datatable like "dbTable". Use dbTable to bind the gridview.

on gridview_rowDeleting ...write following code...

dbTable.Rows[e.RowIndex].Delete();

Gridview.DataSource =dbTable;

GridView.DataBind();

GridView.DeleteRow Method [^] which is used to deletes the record at the specified index from the data source.
Have a look there[^]
