问题描述

我在更新面板中有网格，它有金额列..在"n"行中，我希望在按键上显示所有金额列的总计，并在txtTotalAmt中显示它，对于金额列中的每次插入，都必须添加总计在txtTotalAmt

i have grid in update panel it has amount column.. in that ''n'' rows i want total of all amount column on keypress and display it in txtTotalAmt,for each insertion of amount in amount column it has to add total in txtTotalAmt

推荐答案

中，您可以将Java脚本用于按键事件.
或者您可以使用gridview的文本框文本更改事件.

为此，您需要在行绑定事件中绑定事件处理程序

you can use java script for key press event..

or u can use textbox text changed event of gridview.

for that u need to bind event handler in row bound event

尝试以下代码:-

Hi Kiirrii

Try this code:-

private void DataGridView1_KeyPress(object sender, KeyPressEventArgs e)
     {
       foreach(DataGridViewRow row in DataGridView1.Rows)
        {
          txtTotalAmt.Text = Convert.ToString(Convert.ToDouble(txtTotAmount.Text)+
                             Convert.ToDouble(row.Cells["amount"].value))
        }
     }

希望这项工作!!
