推荐答案

您的意思是类似MS Access的记录视图吗?

您可以使用数据集来绑定字段

Do you mean something like MS Access''s record view?

You Could use a dataset to bind fields

首先必须编写一个方法[ShowData()]，通过该方法我们可以显示在给定控件中填充的整个数据...在页面加载之前声明一个变量(BILLNo).然后在每个按钮中单击即可写入，

私有void btnFirst_Click(对象发送者，EventArgs e)
{
如果(BILLNo == 1)
{
MessageBox.Show(已经在首页...！");
}
其他
{
BILLNo = 1;
ShowData();
}


}


私有无效btnPrev_Click(对象发送者，EventArgs e)
{
如果(BILLNo == 1)
{
MessageBox.Show(已在第一页..！");
}
其他
{

BILLNo--;
ShowData();

}
}

私有无效btnNext_Click(对象发送者，EventArgs e)
{

如果(BILLNo == bill)
{
MessageBox.Show(已在最后一页.！");
}
其他
{

BILLNo ++;
ShowData();
}

}

私有void btnLast_Click(对象发送者，EventArgs e)
{

如果(BILLNo == bill)
{
MessageBox.Show(已在最后一页.！");
}
其他
{

BILLNo = bill;
ShowData();
}
}

First have to write a method[ShowData()] through which we can show the entire data which are populating in the given controls...and have to declare a variable(BILLNo) before pageload.Then in every button click just write,

private void btnFirst_Click(object sender, EventArgs e)
{
if (BILLNo == 1)
{
MessageBox.Show("Already at First Page...!");
}
else
{
BILLNo = 1;
ShowData();
}


}


private void btnPrev_Click(object sender, EventArgs e)
{
if (BILLNo == 1)
{
MessageBox.Show("Already at First Page..!");
}
else
{

BILLNo--;
ShowData();

}
}

private void btnNext_Click(object sender, EventArgs e)
{

if (BILLNo==bill)
{
MessageBox.Show("Already at Last Page..!");
}
else
{

BILLNo++;
ShowData();
}

}

private void btnLast_Click(object sender, EventArgs e)
{

if (BILLNo==bill)
{
MessageBox.Show("Already at Last Page..!");
}
else
{

BILLNo =bill;
ShowData();
}
}
