,因为你有页码,为什么不创建一个列表(或使用字典的页码作为重点) ,然后在按钮处理程序中>>和< <收集当前页面的文本(并将其放入列表或字典中),并将其替换为上一页(来自列表或字典)的文本。
代码可能是这个样子:
public partial class Form1 : Form
{
Dictionary<Decimal, String> TextInfo;
public Form1()
{
InitializeComponent();
TextInfo= new Dictionary<Decimal, String>();
}
private void Form1_Load(object sender, EventArgs e)
{
numPage.Value = 1;
}
private void bnForward_Click(object sender, EventArgs e)
{
if (TextInfo.ContainsKey(numPage.Value))
{
TextInfo[numPage.Value] = textBox1.Text;
}
else
{
TextInfo.Add(numPage.Value, textBox1.Text);
}
numPage.Value++;
if (TextInfo.ContainsKey(numPage.Value))
{
textBox1.Text = TextInfo[numPage.Value];
}
else
{
textBox1.Text = "";
}
}
private void bnBack_Click(object sender, EventArgs e)
{
if (numPage.Value == 1)
return;
if (TextInfo.ContainsKey(numPage.Value))
{
TextInfo[numPage.Value] = textBox1.Text;
}
else
{
TextInfo.Add(numPage.Value, textBox1.Text);
}
numPage.Value--;
if (TextInfo.ContainsKey(numPage.Value))
{
textBox1.Text = TextInfo[numPage.Value];
}
else
{
textBox1.Text = "";
}
}
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
}
}
