GridView更新和删除显示提示信息
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#" %>
<script runat="server">
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();
}
