    <p>I was looking at that form earlier, the one you just found, which is what prompted me to ask. The methods below seem to be the ones I'm focusing on the most as it would seem they are responsible for the population of the check box and the checking of each entry. </p> <p>The thing is, what you have now is good, you would just have to substitute your checkbox control into the code rather than create one like they do.</p> <p>EDIT: I went through the <a href="http://www.telerik.com/community/code-library/aspnet-ajax/scheduler/customize-the-advanced-form-with-the-advanced-template-user-controls.aspx" rel="nofollow">Program</a> to see what gets called <strong>in order</strong>, so that you may adjust them accordingly to fit your data.</p> <pre><code>protected void Page_Load(object sender, EventArgs e) { SemanticCheckBoxList resourceValue = new SemanticCheckBoxList(); resourceValue.ID = "ResourceValue"; ResourceValuesPlaceHolder.Controls.Add(resourceValue); if (resourceValue.Items.Count == 0) { PopulateResources(); MarkSelectedResources(); } } private void PopulateResources() { foreach (Resource res in GetResources(Type)) { ResourceValue.Items.Add(new ListItem(res.Text, SerializeResourceKey(res.Key))); } } private IEnumerable&lt;Resource&gt; GetResources(string resType) { List&lt;Resource&gt; availableResources = new List&lt;Resource&gt;(); IEnumerable&lt;Resource&gt; resources = Owner.Resources.GetResourcesByType(resType); foreach (Resource res in resources) { if (IncludeResource(res)) { availableResources.Add(res); } } return availableResources; } private bool IncludeResource(Resource res) { return res.Available || ResourceIsInUse(res); } private string SerializeResourceKey(object key) { LosFormatter output = new LosFormatter(); StringWriter writer = new StringWriter(); output.Serialize(writer, key); return writer.ToString(); } private void MarkSelectedResources() { foreach (Resource res in Appointment.Resources.GetResourcesByType(Type)) { ResourceValue.Items.FindByValue(SerializeResourceKey(res.Key)).Selected = true; } } </code></pre> <p>I'd think the code via the page load wouldn't be used in yours, you would just need to call the methods inside the conditional if statement.</p>

    1. COI implemented the controls from the project you linked and my scheduler is now using that grid with the multiple values resource control (excluding the provider, I'm using the ResourceTypes field). But I can't for the life of me get the program to select more than one of the resources whose relationship are defined in the database. When I put a breakpoint and step through the MarkSelectedResources() method, the call to Appointment.Resources.GetResourcesByType(Type) only returns one of the resources.

    2. COWhen you step through the code and get to foreach (Resource res in resources), how many resources is your scheduler pulling. The example has 3 students and when it gets to the private IEnumerable<Resource> GetResources(string resType) method, you can see it is pulling the correct amount and then proceeding to mark them in a different method. http://i.imgur.com/MqxMf.png

    3. COI'm thinking I may know what the problem is, but it's frowned upon to chat in the comments. Think you could possibly join the Chat room called Telerik, located at the top of this site? I'm the only one in there and could probably help you out.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
