推荐答案

试试这个：

分配：

Try this:
Assign:

static int f;
static string chain;

在删除按钮中，gridview的click事件使用此代码段：

In the delete button click event of gridview use this code snippet:

using (GridViewRow row = (GridViewRow)((ImageButton)sender).Parent.Parent)
       {

           Label lblid1 = (Label)row.FindControl("lbl_id");
           int id1 = Convert.ToInt16(lblid1.Text);

           if (f == 0)
           {
               chain += id1.ToString();
           }
           else if (f != 0)
           {
               chain += ',' + id1.ToString();
           }

           f++;

           ImageButton btn = (ImageButton)sender;

           GridView1.Rows[row.RowIndex].Visible = false;

       }

和完整按钮点击事件

and in complete button click event

string[] text = chain.Split(',');
 foreach(string word in text)
 {
//delete query here where id=word
//Console.WriteLine(word);  
 }


chain = "";

或试试：



1.从删除按钮上选定的gridview行获取ID单击



2.从Datasource（DataTable或DataSet）中删除特定记录并将选定的ID存储在变量



3.然后再将它与gridview绑定



4.on完成按钮点击获取id并删除它。

尝试使用

RemoveAt()

方法对gridview行进行软删除。

这不会从数据库中删除，只能从gridview集合中删除。

method for the gridview rows to have a soft delete.
This wont delete from the DB but only from the gridview collection.

首先需要在数据库表和列中输入列'状态' 'status'的属性将Default Value或Binding属性设置为1，因此对于每个新条目'Status'列自动设置为1.然后使用'status = 1'的行加载datagrid视图，如

First you need to and a column 'status' in your DB Table and in the Column properties of 'status' Set the Default Value or Binding property to 1 , so for every new entry 'Status' column is automatically set to 1. Then load your datagrid view with rows having 'status=1' like

select * from [Table_name] where status=1

然后在行删除网格视图事件中你应该更新你需要删除的记录状态为0

Then in the row deleting event of grid view you should update the status of record u need to delete to 0

string str = GridView1.DataKeys[e.RowIndex].Values["id"].ToString(); 
        SqlDataAdapter da = new SqlDataAdapter("UPDATE [Table_name] set status=0 WHERE id = '" + str + "' ", connStr);

然后再次调用函数加载网格，

then again call the function to load grid,
