GridView更新和删除显示提示信息

来源：互联网发布：oppo手机查看mac地址编辑：程序博客网时间：2024/05/06 13:10

以前做Asp.Net 1.X是经常会碰到处理列表控件的提示情况，现在开始学习Asp.Net2.0了，用GridView完成相似的事情，更新和删除显示提示信息，确认后使用SqlDataSource 完成数据库操作的　

<%@ Page Language="C#" %>

    void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        switch (e.CommandName.ToLower())
        {
            case "edit":
                GridView1.Columns[0].Visible = false;
                GridView1.Columns[1].Visible = true;
                break;
            case "update":
            case "delete":
            case "cancel":
                GridView1.Columns[0].Visible = true;
                GridView1.Columns[1].Visible = false;
                break;
            default:
                // Do nothing.
                break;
        }
    }

    void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {
        int index = GridView1.EditIndex;
        GridViewRow row = GridView1.Rows[index];

TextBox firstNameTextBox = (TextBox)row.Cells[1].FindControl("FirstNameTextBox");

        String firstName = "";
        if (firstNameTextBox != null)
        {
            firstName = firstNameTextBox.Text;
        }

TextBox lastNameTextBox = (TextBox)row.Cells[2].FindControl("LastNameTextBox");

        String lastName = "";
        if (lastNameTextBox != null)
        {
            lastName = lastNameTextBox.Text;
        }

Parameter lastNameParameter = new Parameter("au_lname", TypeCode.String, lastName);
Parameter firstNameParameter = new Parameter("au_fname", TypeCode.String, firstName);

        SqlDataSource1.UpdateParameters.Clear();
        SqlDataSource1.UpdateParameters.Add(lastNameParameter);
        SqlDataSource1.UpdateParameters.Add(firstNameParameter);
    }

    void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        SqlDataSource1.DeleteParameters.Clear();
    }
