检查gridview内的复选框是否已选中？ [英] check checkbox inside gridview either it is checked or not?

问题描述

大家好，

我有gridview，其中包含复选框作为templatefield。我已经尝试过如此努力，但我仍然无法获得所需的结果，即如果选中复选框，则执行action-1否则执行action-2，但每次执行action-2.Below是我的代码我需要你的帮助。



Gridview代码：< br $>

< asp：GridView ID =   final runat =   server AutoGenerateColumns =   False; >  
<柱体和GT; 
< asp：BoundField DataField =   name HeaderText =  员工姓名 SortExpression =  日期 /> 
< asp：BoundField DataField =   ldate HeaderText =  离开日期 SortExpression =   ldate 
 /> 
< asp：TemplateField HeaderText =  半/全 >  
< ItemTemplate> 
< asp：RadioButtonList ID =   RadioButtonList1 runat =   server >  
< asp：ListItem Enabled =   true值=  一半>一半< /   asp：ListItem  >  
< asp：ListItem已启用=   true值=  完整>完整< /   asp：ListItem  >  
 < /   asp：RadioButtonList  >  
 < /   ItemTemplate  >  
 < /   asp：TemplateField  >  
< asp：TemplateField HeaderText = < span class =code-string> 批准 >  
 <&的ItemTemplate GT; 
< asp：CheckBox ID =   CheckBox1 runat =   server /> 
 < /   ItemTemplate  >  
 < /   asp：TemplateField   >  
 < /  列 >  
 < /   asp：GridView  >  

代码我已检查过收音机和复选框：

 DataTable dtable =  new  DataTable（）; 
 dtable.Columns.Add（ new  DataColumn（ 日期， typeof （DateTime）））; 
 dtable.Columns.Add（ new  DataColumn（ 半/完全， typeof （ float ）））; 
 dtable.Columns.Add（ new  DataColumn（ 状态， typeof （ string ）））; 
会话[  dt] = dtable; 
 SqlConnection conn =  new  SqlConnection（）; 
 conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings [  leave]。ConnectionString ; 
 conn.Open（）; 
  foreach （GridViewRow gvrow  in  final.Rows）
 {
 dtable =（DataTable）Session [  dt]; 
 CheckBox chk =（CheckBox）gvrow.FindControl（  CheckBox1）; 
  if （chk！=  null & chk.Checked）
 {
 RadioButtonList rButton =（RadioButtonList）gvrow.FindControl（  RadioButtonList1）; 
  if （rButton.SelectedValue ==  一半）
 {
  //  执行操作-1  
} 
 其他 
 {
  //  < span class =code-comment>执行操作-1  
} 
} 
  其他 
 {
执行行动-2 
}  
} 

每次它进入了最后的其他...为什么？Anyhelp真的很有意思，因为我正在尝试这个以来的一周。

解决方案

嘿Rohan，



除了以下内容之外，您所做的事情是正确的。

  foreach （GridView行gvrow  in  final.Rows）
 {
 dtable =（DataTable）Session [  dt]; 
 CheckBox chk =（CheckBox）gvrow.FindControl（  CheckBox1）; 
  如果（chk！=  null & chk.Checked）
 { 
 RadioButtonList rButton =（RadioButtonList）gvrow.FindControl（  RadioButtonList1）; 
  if （rButton.SelectedValue ==  一半）
 {
  //  执行操作-1  
} 
 其他 
 {
  //  < span class =code-comment>执行操作-1  
} 
} 
 其他 
 {
执行操作-2 
} 
} 

这表示您的复选框不在所有选中。请填写网格并检查代码部分中的网格填充方法

  if （！IsPostBack）
 { 
  //  使用复选框填充网格的代码 
} 

好运

Hi everyone,
I have gridview which contains the checkbox as templatefield.I have tried so hard but i am still unable to get the desired results,that is if check box is checked,than perform action-1 otherwise perform action-2,but everytime it is performing action-2.Below is my code i need little help from your side.

Gridview code:

<asp:GridView ID="final" runat="server" AutoGenerateColumns="False";>
        <Columns>
<asp:BoundField DataField="name" HeaderText="Employee Name" SortExpression="date" />
<asp:BoundField DataField="ldate" HeaderText="Date Of Leave" SortExpression="ldate"
                   />
<asp:TemplateField HeaderText="Half/Full">
   <ItemTemplate>
            <asp:RadioButtonList ID="RadioButtonList1" runat="server">
                            <asp:ListItem Enabled="true" Value="Half">Half</asp:ListItem>
                            <asp:ListItem Enabled="true" Value="Full">Full</asp:ListItem>
           </asp:RadioButtonList>
   </ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Approve">
    <ItemTemplate>
     <asp:CheckBox ID="CheckBox1" runat="server" />
    </ItemTemplate>
</asp:TemplateField>
        </Columns>
</asp:GridView>

code i have made to check the radio and checkbox:

DataTable dtable = new DataTable();
dtable.Columns.Add(new DataColumn("Date", typeof(DateTime)));
dtable.Columns.Add(new DataColumn("Half/Full", typeof(float)));
dtable.Columns.Add(new DataColumn("Status", typeof(string)));
Session["dt"] = dtable;
SqlConnection conn = new SqlConnection();
conn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["leave"].ConnectionString;
conn.Open();
foreach (GridViewRow gvrow in final.Rows)
{
     dtable=(DataTable)Session["dt"];
     CheckBox chk = (CheckBox)gvrow.FindControl("CheckBox1");
     if (chk != null & chk.Checked)
     {
          RadioButtonList rButton = (RadioButtonList)gvrow.FindControl("RadioButtonList1");
          if (rButton.SelectedValue == "Half")
          {
               //perform action-1
          }
          else
          {
              //perform action-1
          }
     }
  else
     {
          perform action-2
     }
}

everytime its going into the last else...why?Anyhelp would be realy realy appreciated as i am trying for this since last one week.

解决方案

Hey Rohan,

What ever the things you have done is correct except the following thing.

foreach (GridViewRow gvrow in final.Rows)
{
     dtable=(DataTable)Session["dt"];
     CheckBox chk = (CheckBox)gvrow.FindControl("CheckBox1");
     if (chk != null & chk.Checked)
     {
          RadioButtonList rButton = (RadioButtonList)gvrow.FindControl("RadioButtonList1");
          if (rButton.SelectedValue == "Half")
          {
               //perform action-1
          }
          else
          {
              //perform action-1
          }
     }
  else
     {
          perform action-2
     }
}

This shows your check box is not at all getting selected.Please fill the grid and check the grid fill method in the code section

if(!IsPostBack)
{
    //Code to fill Grid with check box
}

GoodLuck
