Binding to a checkbox

Posted By:      Posted Date: October 06, 2010    Points: 0   Category :ASP.Net
 

I have the following code:

 <label>Date Code Check:</label>
        <div class="editor-field ">
                <%= Html.CheckBoxFor(Function(m) m.PackingCheck.Date_Code_Check)%>
                <%= Html.ValidationMessageFor(Function(m) m.PackingCheck.Date_Code_Check)%>
        </div>


And I am getting the following error: 

Templates can be used only with field access,
property access, single-dimension array index, or single-parameter custom indexer expressions.

I am just starting to learn MVC and I am liking it.  My editor-fields for textboxes work just fine.

Thanks for the information and help.

Brad

Binding Nested Listviews in MVC ViewPage

  

I am a longtime .NET developer but for big applications and services.  This is my first asp.net project and I have chosen MVC.   I have a need for nesting a ListView within a ListView.  In this simple catalog app, I have EF 4 Entities that are Categories, SubCategories, ItemTypes, and Items.

My goal is to display a 5 column layout of SubCategories with their ItemTypes below them in a ViewPage.  I did just fine with it done out in C# as server directives such as:

    var subcats = Model.SubCategory.ToArray();
    var nrSubCats = subcats.Count();
    var rows = (nrSubCats/5) + (((nrSubCats % 5) > 0) ? 1 : 0);
    for (var row = 0; row < rows; row++)
    { %>
        <div style="width: 100%; float: left; clear: right;">
        <%
        var start = row * 5;
        for (var i = start; (i < start + 5) && (i < nrSubCats); i++)
        {
        var subcat = subcats[i];
        %>
            <div style="float: left; clear: right; width: 20%; margin-left: 5;">
                <h2> <%:subcat.Name%></h2>
                <ul>
                    <%
                    foreach (var its in subcat.ItemType)
                    {%>
                        <li>
                            <%:Html.
