Create Drawer items server-side
The Drawer renders its items client-side based on the ItemsTemplate. The code below shows how you can abstract the string formatting and just create custom objects which you can pass to the method and receive a fully functionaly ItemsTemplate:
public class MyDrawerItem
{
public string Text { get; set; }
public bool IsSelected { get; set; }
public bool IsSeparator { get; set; }
}
public string itemTemplate = "<li data-role='drawer-item' {1}><span class='k-item-text'>{0}</span></li>";
public string selectedItemClass = "class='k-state-selected'";
public string separatorTemplate = "<li data-role='drawer-separator'></li>";
public string GetItems(IEnumerable<MyDrawerItem> items)
{
StringBuilder str = new StringBuilder("<ul>");
foreach (var item in items)
{
var itemContent = item.IsSeparator ? separatorTemplate :
string.Format(itemTemplate, item.Text, item.IsSelected ? selectedItemClass : string.Empty);
str.Append(itemContent);
}
str.Append("</ul>");
return str.ToString();
}
protected void Page_Load(object sender, EventArgs e)
{
var data = new List<MyDrawerItem>()
{
new MyDrawerItem(){ Text = "Item 1"},
new MyDrawerItem(){ Text = "Item 2"},
new MyDrawerItem(){ IsSeparator = true },
new MyDrawerItem(){ Text = "Item 3", IsSelected=true},
new MyDrawerItem(){ Text = "Item 4"},
new MyDrawerItem(){ IsSeparator = true },
new MyDrawerItem(){ Text = "Item 5"},
new MyDrawerItem(){ Text = "Item 6"},
new MyDrawerItem(){ Text = "Item 7"},
new MyDrawerItem(){ IsSeparator = true },
new MyDrawerItem(){ Text = "Item 8"},
new MyDrawerItem(){ Text = "Item 9"},
new MyDrawerItem(){ Text = "Item 10"},
};
RadDrawer1.ItemsTemplate = GetItems(data);
}
