And? Did you check the table that you passed into the page to see if it has a 'LoginName 'column. It's telling you that the column isn't in the table you gave it and if it's telling you this, it's correct.

Solution 1

Notice you are creating a new DataTable but have not given it a schema ("layout"), so no columns exist on it.

Try something like:

DataTable dt = new DataTable();

dt.Columns.Add("LoginName");
dt.Columns.Add("NavigateUrl");

DataRow row = dt.NewRow();

or populate the datatable from a data source

DataBinding: 'System.Web.UI.WebControls.RepeaterItem' does not contain a property with the name 'LoginName'.

Add the columns to the datatable [Below two additional code lines] =

C#

DataTable dt = new DataTable();
dt.Columns.Add("LoginName", Type.GetType("System.String"));
dt.Columns.Add("NavigateUrl", Type.GetType("System.String"));
DataRow row = dt.NewRow();
row["LoginName"] = "pallavi";
row["NavigateUrl"] = "xyz";
dt.Rows.Add(row);

RepeaterLinks.DataSource = dt;
RepeaterLinks.DataBind();

Please check the code for design page i.e. aspx page :-

C#

 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default4.aspx.cs" Inherits="Default4" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:repeater id="RepeaterLinks" runat="server" xmlns:asp="#unknown">
         <itemtemplate>
            <asp:hyperlink id="HyperLink2">
                runat="server" 
                NavigateUrl='<%# DataBinder.Eval(Container.DataItem, "NavigateUrl") %>'> <%# DataBinder.Eval(Container.DataItem, "LoginName") %></asp:hyperlink>
             <br />
        </itemtemplate>
        </asp:repeater>
    </div>
    </form>
</body>
</html>

Please check the below code behind code :-

C#

protected void Page_Load(object sender, EventArgs e)
{
    DataTable dt = new DataTable();
    dt.Columns.Add("LoginName", Type.GetType("System.String"));
    dt.Columns.Add("NavigateUrl", Type.GetType("System.String"));
    DataRow row = dt.NewRow();
    row["LoginName"] = "LoginName";
    row["NavigateUrl"] = "Default.aspx";
    dt.Rows.Add(row);

    row = dt.NewRow();
    row["LoginName"] = "LoginName1";
    row["NavigateUrl"] = "Default2.aspx";
    dt.Rows.Add(row);

    RepeaterLinks.DataSource = dt;
    RepeaterLinks.DataBind();
}
