asp.net Datagrid问题 [英] asp.net Datagrid issues

问题描述

我是这个发布的新手，所以......
我有一个数据网格，在一行中有一些金额，在另一行中有一个复选框.我也有一个计算按钮.当我单击计算"按钮时，我希望代码通过数据网格并计算复选框中已检查的每一行的数量，如果未选中复选框，则不应使用该数量.我很困惑，但是到目前为止我已经掌握了编码.它是通过按钮on_Click事件调用的:

hi i''m new at this posting thing so here goes...
I''ve got a datagrid with some amounts in one row and a checkbox in another. I also have a calculate button. When i click the calculate button, i want the code to go through the datagrid and calculate the amounts of each row that has been checked in the checkbox, if a checkbox is not checked, it should not use that amount. I''m stumped, but here''s the coding i''ve got so far. It''s called from the button on_Click event:

foreach (GridViewRow rows in dgServices.Rows)
           {
               CheckBox cb = (CheckBox)rows.FindControl"cbAddTo");
               if (cb.Checked == true)
               {
                   CalculatedItem += float.Parse(dgServices.Rows[0].Cells[8].Text);
               //here''s the problem in the .Rows[0]
}
               else
               {
          //do nothing
               }

               txtTB4V.Text = CalculatedItem.ToString();
           }

所以基本上我需要知道我是否走在正确的轨道上，或者是否有更简单的方法来做到这一点.在此先感谢:)

推荐答案

为什么不只使用循环变量:"rows"

Why not just use the loop variable: "rows"

CalculatedItem += float.Parse(rows.Cells[8].Text);
