Javascript在文本框上显示gridview列的总和。 [英] Javascript to show the gridview column sum on a textbox.

问题描述

先生，我有一个Gridview。我在一个列中的文本框。我需要当我在gridview文本框中输入数字时，它会计算文本框的总和并显示另一个文本框。我的asp代码在这里： -

 < ;   asp：GridView     ID   =  GridOtherFee    runat   =  server    AutoGenerateColumns   =  false     CssClass   =  mGrid    DataSourceID   =  SqlOtherFee >  
 <  列 > ;  
 
 
 <   asp：BoundField     DataField   =  Abb    HeaderText   =  FeeHead    ReadOnly   =  True      HeaderStyle-Width   =  100px  /   >  
 
 <   asp：TemplateField     SortExpression   = 金额    HeaderText   = 金额    ItemStyle-Horizo​​ntalAlign   = 右    HeaderStyle-Horizo​​ntalAlign   = 右      HeaderStyle-Width   =  150px >  
 <   ItemTemplate  >  
 <   asp：TextBox     ID   =  TxtRecd      runat   =  server   宽度  =  100px     AutoPostBack   = < span class =code-keyword> true    CssClass   =  aligntext >  <   / asp：TextBox  >  
 <   / ItemTemplate  >  
 <   / asp：TemplateField  >  
 
 <   /列 >  
 
 <   / asp：GridView  >  

< br $>


< asp：TextBox ID =txtFeeRecdrunat =servername =aWidth =100 pxReadOnly =trueCssClass =aligntext>






当我输入数字时
在gridview txtrecd文本框中显示textfeereced textbox中的显示总和..

解决方案

在某些按钮单击或新行创建或任何您想要的事件上调用此方法

  private   void  GrandTotal（）
 {
  float  GTotal = 0f; 
  for （ int  i =  0 ; i <  GridView1.Rows.Count; i ++）
 {
  String  total =（GridView1.Rows [i] .FindControl（  lblTotal） as  Label）.Text; 
 GTotal + = Convert.ToSingle（total）; 
} 
 txtTotal.text = GTotal.toString（）; 
} 

希望它有所帮助..

解决方案

Call this Method on some button click or on new row creation or whatever event you want to

private void GrandTotal()
    {
     float GTotal = 0f;
     for (int i = 0; i < GridView1.Rows.Count; i++)
     {
        String total = (GridView1.Rows[i].FindControl("lblTotal") as Label).Text;
        GTotal += Convert.ToSingle(total);
     }
     txtTotal.text=GTotal.toString();
    }

Hope it will help..
