如何计算在c＃中选择的单选按钮的数量？ [英] how to count no of radio buttons which are selected in c#?

问题描述

嗨......



i有一个gridview ....在这个gridview中我在每个gridview行中都有两个单选按钮...

1>必须满足

2>不想见面

如何计算在必须见面和不符合中选择的单选按钮的数量???

解决方案

< blockquote>在Gridview ItemTemplate中添加RadioButton列

 <  < span class =code-leadattribute> ItemTemplate  >  <   asp：CheckBox     ID   =  ChkMustMeet    runat   =  server   < span class =code-attribute> AutoPostBack   =  True    /  >  
 <   / ItemTemplate  >  

CodeBehind：

  protected   void  Page_Load（  object  sender，EventArgs e）
 {
  if  
（！ IsPostBack）
 {
 BindGrid（）;  //  网格绑定代码 
} 
  else  
 {
 GetCount（）; 
} 
} 

  private   int  GetCount（）
 {
  int  count =  0 ; 
 GridViewRow row =  null ; 
  for （ int  i =  0 ; i <  GridView1.Rows.Count; i ++）
 {
 row = GridView1.Rows [i]; 
  bool  isChecked =（（RadioButton）row.FindControl（  ChkMustMeet））经过。 
  if （isChecked）
 {
 count ++; 
} 
} 
 返回计数; 
} 

如果您需要每次检查并取消选中使用选择更改的活动，请相应地更改以上内容。



希望这会有所帮助......

你好，

  int  meet =  0 ，dont_meet =  0 ; 
  for （ int  i =  0 ; i <  GridView1.Rows.Count; i ++）
 {
 RadioButton rb1 =（RadioButton）GridView1.Rows [i]。 FindControl（  rd_meet）; 
 RadioButton rb2 =（RadioButton）GridView1.Rows [i] .FindControl（  rd_dontmeet ）; 
  if （rb1.Checked）
 {
 meet ++; 
} 
  if （rb2.Checked）
 {
 dont_meet ++; 
} 
}

2> dont want to meet
how to count no of radio buttons which are selected in "must meet" & "dont meet"???

解决方案

Add RadioButton Columns in the Gridview ItemTemplate

<ItemTemplate><asp:CheckBox ID="ChkMustMeet" runat="server" AutoPostBack="True" />
                   </ItemTemplate>

CodeBehind:

protected void Page_Load(object sender, EventArgs e)
 {
  if 
  (!IsPostBack) 
    { 
      BindGrid(); //Grid Binding code
    }
  else 
    { 
      GetCount(); 
    }
  }

private int GetCount()
    {
        int count = 0;
        GridViewRow row = null;
        for (int i = 0; i < GridView1.Rows.Count; i++)
        {
            row =GridView1.Rows[i];
            bool isChecked = ((RadioButton)row.FindControl("ChkMustMeet")).Checked;
            if (isChecked)
            {
                count++;
            }
        }
       return count; 
    }

Change the above accordingly if you need each time check and uncheck use select changed event.

Hope this helps...

Hello,

int meet=0,dont_meet=0;
for (int i = 0; i < GridView1.Rows.Count; i++)
{
 RadioButton rb1 = (RadioButton)GridView1.Rows[i].FindControl("rd_meet");
 RadioButton rb2 = (RadioButton)GridView1.Rows[i].FindControl("rd_dontmeet");
 if (rb1.Checked)
 { 
    meet++;
 }
 if (rb2.Checked)
 { 
    dont_meet++;
 }
}
