GridView中删除行的方法

我正在尝试实现删除方法并传递删除操作的参数。我正在使用sqldatasource。由于 ID 在我的 gridview 中没有列，如何获取 ID 的值并将其设置为删除参数？

ID 不需要 GridView 中的列，只要它位于数据源中即可。这是一个简单的 GridView 教程，解释了该过程...

http://www.aspdotnetcodes.com/GridView_Insert_Edit_Update_Delete.aspx

他们的 RowDeleting 处理程序...

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  customer.Delete(GridView1.DataKeys[e.RowIndex].Values[0].ToString());
  FillCustomerInGrid();
}

ID doesn't need a column in the GridView, as long as it is in the datasource. Here's a simple GridView tutorial explaining the procedure...

Their RowDeleting handler...

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
  customer.Delete(GridView1.DataKeys[e.RowIndex].Values[0].ToString());
  FillCustomerInGrid();
}

您可以设置一个方法来处理 gridview 的 OnRowDeleting 事件，取消那里的删除，并实现您自己的逻辑来执行删除（即基于 id 之外的某些字段进行删除）：

<asp:GridView OnRowDeleting="gridview_rowdeleting" />


protected void gridview_rowdeleting(Object sender, GridViewDeleteEventArgs e)
    {
    e.Cancel = true;
        // logic for performing delete here...e.Rows returns the collection of deleted rows so you can access whatever values you need...e.Rows[0].Cells[0] gives the value in the first column for the first deleted row for example
    }

You can set up a method to handle the gridview's OnRowDeleting event, cancel the delete there, and implement your own logic to perform the delete (ie delete based on some field besides id):

<asp:GridView OnRowDeleting="gridview_rowdeleting" />


protected void gridview_rowdeleting(Object sender, GridViewDeleteEventArgs e)
    {
    e.Cancel = true;
        // logic for performing delete here...e.Rows returns the collection of deleted rows so you can access whatever values you need...e.Rows[0].Cells[0] gives the value in the first column for the first deleted row for example
    }
