如何为转发器内的复选框列表提供DataText字段，DataValue字段值 [英] How to give the DataText field ,DataValue field value for a checkbox list inside a repeater

问题描述

我在转发器控件中使用了一个checkboxlist。我正在绑定像这样的复选框列表



< asp：CheckBoxList ID =CheckBoxList1runat =serverDataSource ='<％＃（（系统。 Data.DataRowView）Container.DataItem）.Row.GetChildRows（Child）％>'>



但是我无法使用datatext字段和Datavalue字段属性...如何给出这个。

解决方案

为Property取一个类。

  public   class  CheckBoxValues 
 {
  public   string  ValueToDisplay { get ;  set ;} 
  public   string  ValueToBind { get ;  set ;} 
} 

现在获取一个对象列表这个类和绑定此列表wi你的价值就像......

 ... 
 List< checkboxvalues> ChkList =  new  List< checkboxvalues>（）; 
  //  获取类的新对象。 
 CheckBoxValues obj; 
 obj =  new  CheckBoxValues（）; 
 obj.ValueToDisplay =   Cricket; 
 obj.ValueToBind =   crick; 
 ChkList。 add （obj）; 
  //  让我们添加另一个对象 
 obj =  new  CheckBoxValues（）; 
 obj.ValueToDisplay =   Football; 
 obj.ValueToBind =   ft; 
 ChkList。 add （obj）; 
  //  您也可以动态添加。 
 ... 
  //  现在将其作为复选框列表的文本字段和值字段。 
 chklistControll.DataSource = ChkList; 
 chklistControll.DataTextField =   ValueToDisplay; 
 chklistControll.DataValueField =   ValueToBind; 
 chklistControll.DataBind（）; 

希望这个帮助

如果它解决了您的问题，请将其标记为答案。

 <   asp：checkboxlist     runat   =  server    datatextfield   =  [ColumnName]    datavaluefield   =  [ColumnName]    /  >  

I am using a checkboxlist inside a repeater control. i am binding the checkbox list like this

<asp:CheckBoxList ID="CheckBoxList1" runat="server" DataSource='<%# ((System.Data.DataRowView)Container.DataItem).Row.GetChildRows("Child") %>' >

but i am not able to use the datatext field and Datavalue field property...How to give this.

解决方案

take a class for Property.

public class CheckBoxValues
{
   public string ValueToDisplay{get;set;}
   public string ValueToBind{get;set;}
}

Now Take a list of object of this class and bind this list with your value like...

...
List<checkboxvalues> ChkList =  new List<checkboxvalues>();
//take new object of class.
CheckBoxValues obj;
obj = new CheckBoxValues();
obj.ValueToDisplay = "Cricket";
obj.ValueToBind = "crick";
ChkList.add(obj);
//lets add another object
obj = new CheckBoxValues();
obj.ValueToDisplay = "Football";
obj.ValueToBind = "ft";
ChkList.add(obj);
//you can also add this dynamically.
...
//now give it as your checkBox list's textfield and valuefield.
chklistControll.DataSource = ChkList;
chklistControll.DataTextField = "ValueToDisplay";
chklistControll.DataValueField = "ValueToBind";
chklistControll.DataBind();

Hope This Help
