Bug in setting value of UnboundCheckBoxField from code-behind?
posted

Hi,

I have an issue when setting the value of an UnboundCheckBoxField from code-behind. Here is some sample code:

Markup:

<%@ Page Language="C#" AutoEventWireup="false" CodeBehind="Default.aspx.cs" Inherits="UnboundCheckBoxFields._Default" %>

<%@ Register Assembly="Infragistics35.Web.v11.2, Version=11.2.20112.1019, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
    Namespace="Infragistics.Web.UI" TagPrefix="ig" %>

<%@ Register Assembly="Infragistics35.Web.v11.2, Version=11.2.20112.1019, Culture=neutral, PublicKeyToken=7dd5c3163f2cd0cb"
    Namespace="Infragistics.Web.UI.GridControls" TagPrefix="ig" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <ig:WebScriptManager ID="WebScriptManager1" runat="server">
        </ig:WebScriptManager>
        <ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" Width="400px" AutoGenerateColumns="false">
            <Columns>
                <ig:UnboundCheckBoxField Key="Check" ></ig:UnboundCheckBoxField>
                <ig:BoundDataField Key="Value" DataFieldName="BoundFieldName" ></ig:BoundDataField>
            </Columns>
        </ig:WebDataGrid>
    </div>
    <asp:Button ID="btnPostBack" runat="server" />
    </form>
</body>
</html>

 

Code-behind:

public partial class _Default : System.Web.UI.Page
    {
        protected override void OnInit(EventArgs e)
        {
           
            base.OnInit(e);

            Load += Page_Load;
        }
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                List<MyClass> list = new List<MyClass>();
                for (int i = 0; i < 10; i++)
                {
                    list.Add(new MyClass(i));
                }

                WebDataGrid1.DataSource = list;
                WebDataGrid1.DataBind();

                foreach (GridRecord gridRecord in WebDataGrid1.Rows)
                {
                    gridRecord.Items[0].Value = Convert.ToInt32(gridRecord.Items[1].Text) % 2 == 0;
                }
            }
        }


    }

    public class MyClass
    {
        public int BoundFieldName { get; set; }
       
        public MyClass(int boundFieldValue)
        {
            BoundFieldName = boundFieldValue;
        }
    }

 

The rows with values 0,2,4,6,8 are checked, but doing postback by clicking the button removes all rows from the grid. If I set EnableDataViewState to true the data is displayed after postback, but no rows are checked, neither on initial load nor after postback.

Is there another way to solve this?

I am using version 11.2.20112.1019.
