如何将文本框输入传递给asp.net中的gridview ?

I have two textbox and one gridview in my webform. The gridview is binded with database. But I want to add one more column on runtime which will be the textbox input from the webform. Because the scenario is like: I am maintaining two formula to calculate some percentage using the two textbox and the client wants to see this calculation for each row in the gridview.

我的webform中有两个文本框和一个gridview。gridview与数据库绑定。但是我想在运行时上再添加一列，这是来自webform的文本框输入。因为场景是这样的:我使用两个文本框来维护两个公式来计算百分比，而客户端希望看到gridview中每一行的计算。

But I cannot do this.

但我做不到。

Is there anyone who can help me on this please? May be some suggestion.

有谁能在这件事上帮助我吗?可能是一些建议。

Thanks in advance.

提前谢谢。

You could add the column in your GridView markup with a label control to display the result as follows.

您可以在GridView标记中添加带有标签控件的列，以显示如下所示的结果。

Here is the markup needed, please note Visible is set to false.

这是需要的标记，请注意可见被设置为false。

<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField Visible="false">
    <ItemTemplate>
        <asp:Label ID="label1" runat="server"></asp:Label>
    </ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

Use the RowDataBound event to find the label and calculate your result as below:

使用RowDataBound事件查找标签并计算结果如下:

void GridView1GridView_RowDataBound(Object sender, GridViewRowEventArgs e)
{ 
 if(e.Row.RowType == DataControlRowType.DataRow)
 {
  //find the control
  var label1 = e.Item.FindControl("label1") as Label;
  if (label1 != null)
  {
   if (!string.IsNullOrEmpty(tbInput1.Text) && !string.IsNullOrEmpty(tbInput2.Text))
   {
      // Do the calculation and set the label
      label1.Text = tbInput1.Text + tbInput2.Text;
      // Make the column visible
      GridView1.Columns[0].Visible = true;
   }
  }
 }
}

Please forgive any errors, I have not tested the above.

请原谅我有任何错误，我没有测试过以上。
