    <p>I have 5 cascading drop downs on my page. I'd like them to <strong>try</strong> cascade, but if it doesn't cascade - gracefully stop trying or erroring-out. I would also like all of the comboboxes to be enabled, rather than be disabled until the previous combobox is filled.</p> <p>I've tried to .Enable(true) on the enabled fluent API, but the dropdowns are still disabled. Any idea how I can go about doing this?</p> <pre><code> &lt;div class="span5"&gt; &lt;div class="control-group"&gt; @Html.Label("Product Types", new { @class = "control-label" }) &lt;div class="controls"&gt; @( Html.Telerik().ComboBox() .Name("drpProductTypes") .BindTo(new SelectList(ViewBag.drpProductTypes)) .Placeholder("Select Category...") .CascadeTo("drpClass1").Enable(true) ) &lt;/div&gt; &lt;div class="fix"&gt;&lt;/div&gt; &lt;/div&gt; &lt;div class="control-group"&gt; @Html.Label("Class 1", new { @class = "control-label" }) &lt;div class="controls"&gt; @( Html.Telerik().ComboBox() .Name("drpClass1") .DataBinding(binding =&gt; binding.Ajax().Select("_GetDropDownClassOne", "List")) .Placeholder("Select Class 1...") .CascadeTo("drpClass2").Enable(true) ) &lt;/div&gt; &lt;div class="fix"&gt;&lt;/div&gt; &lt;/div&gt; &lt;div class="control-group"&gt; @Html.Label("Class 2", new { @class = "control-label" }) &lt;div class="controls"&gt; @( Html.Telerik().ComboBox() .Name("drpClass2") .DataBinding(binding =&gt; binding.Ajax().Select("_GetDropDownClassTwo", "List")) .Placeholder("Select Class 2...") .CascadeTo("drpClass3").Enable(true) ) &lt;/div&gt; &lt;div class="fix"&gt;&lt;/div&gt; &lt;/div&gt; &lt;div class="control-group"&gt; @Html.Label("Class 3", new { @class = "control-label" }) &lt;div class="controls"&gt; @( Html.Telerik().ComboBox() .Name("drpClass3") .DataBinding(binding =&gt; binding.Ajax().Select("_GetDropDownClassThree", "List")) .Placeholder("Select Class 3...") .CascadeTo("drpClass4").Enable(true) ) &lt;/div&gt; &lt;div class="fix"&gt;&lt;/div&gt; &lt;/div&gt; &lt;div class="control-group"&gt; @Html.Label("Class 4", new { @class = "control-label" }) &lt;div class="controls"&gt; @( Html.Telerik().ComboBox() .Name("drpClass4") .DataBinding(binding =&gt; binding.Ajax().Select("_GetDropDownClassFour", "List")) .Placeholder("Select Class 4...").Enable(true) ) &lt;/div&gt; &lt;div class="fix"&gt;&lt;/div&gt; &lt;/div&gt; </code></pre> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
