我的gridview asp.net有问题请帮忙！ [英] i have a problem with my gridview asp.net please help!!!

问题描述

你好，

在我的项目中，我有一个gridview，我想得到文本框中特定列的总和，但我无法访问其单元格并获取值

i认为这是因为我在GridView中使用INSERT，EDIT，DELETE的TemplateFields和FooterTemplate

是问题???我该如何解决？



i甚至无法使用此获取单元格值：



Label1.Text = GridView1.Rows [0] .Cells [0] .Text;



它适用于其他gridview而不是这一个



pleaaase help !!!!!



谢谢。

hello,
in my project , i have a gridview and i want to get the sum of a specific column in a textbox, but i'm not able to access its cells and get the values
i think that it's because of TemplateFields and FooterTemplate that i'm using to INSERT,EDIT,DELETE in my GridView
is that the problem??? and how can i solve it???

i can't even get the cell value using this:

Label1.Text = GridView1.Rows[0].Cells[0].Text;

it works for other gridview but not this one

pleaaase help!!!!!

thank you.

试试这个..

try this ..

for (int i = 0; i < grdvtest.Rows.Count; i++)
        {
            string value= ((TextBox)grdvtest.Rows[i].Cells[1].FindControl("txtname")).Text.Trim();

}



试着拿走这样的价值



txtname是模板字段中的文本框...........

如果有任何问题请告诉

}

try to take the value in this way

txtname is the textbox inside the template field...........
if any problm pls tell

试试这个：

Try this:

int total = 0;
TextBox textbox;
foreach(GridViewRow row in GridView1.Rows)
{
   textbox = (TextBox)row.Cells[0].FindControl("name of textbox");

      int number;
      bool result = Int32.TryParse(textbox.Text.Trim(), out number);
      if (result) // if true that the textbox value is int32
      {
         total += number;
      }
}

您应该使用Int32.TryParse来验证文本框值是否为数字。

如果你期望十进制数，然后使用Decimal.TryParse方法。

You should use Int32.TryParse to validate that the textbox value is number.
If you expect decimal number, then use Decimal.TryParse method instead.
