Specifying Templates

Basic Information

Templates define the way data is rendered inside of DataView. You can define multiple templates and switch between them dynamically.

view = new dhtmlXDataView({
    container:"data_container",
    type:{
        template:"#Package# : #Version#<br/>#Maintainer#",
        height:40
    }
});

The { Package:"a", Version:"b", Maintainer:"c"} will be rendered as:

a : b <br/> c

A template can be defined as a part of the constructor (or not) as:

view.define("type",{
    template:"#Package# : #Version#<br/>#Maintainer#"
});

If you need to provide only a text string and don't need any extra properties, you can use the "template" property directly on the top level (i.e. don't use the type parameter):

view = new dhtmlXDataView({
    container:"data_container",
    template:"#Package# : #Version#<br/>#Maintainer#"
});

Types of Templates

JS string

view.define("type",{
    template:"#Package# : #Version#<br/>#Maintainer#"
});

JS method

view.define("type",{
    template:function(){ return obj.Package +"<br/>"+obj.Maintainer; }
});

HTML container

<textarea id="template_container" rows="5" cols="60">
#Package# : #Version#
<br/>#Maintainer#</textarea>
...
view.define("type",{
    template:"html->template_container",
})

HTML file

view.define("type",{
    template:"http->../common/template.html",
})

Named templates

dhtmlx.Type.add(dhtmlXDataView,{
    name:"dataA",
    template:"#Package# : #Version#<br/>#Maintainer#",
    height:40
});
 
data = new dhtmlXDataView({
    container:"data_container", 
    type:"dataA"
});

Templates Syntax

"#property#" - replaced with a value of the related property

view.define("type",{
    template:"#a# - #b#"
})
// a - b

"{common.property}" - replaced with a constant value from the template

view.define("type",{
    template:"#a# - {common.mydata}",
    mydata:25
})
// a - 25

"{common.method()}" - replaced with the result of a method call

view.define("type",{
    template:"#a# - {common.mymethod()}",
    mymethod:function(obj){
        return obj.b.toUpperCase();
    }
})
// a - B

"#property?valueA:valueB#" - ternary operator

view.define("type",{
    template:"#a# - #flag?exist:not exist#"
})
// a - not exist

"{-obj" - replaced with #

Changing Parameters of Templates

Sometimes it can be useful to change some parameter of a template. As a result, the view will be repainted with new configuration.

view.customize({
    height:100
});

If you define some property in template as {common.some}, you will be able to change it any time by using the "customize" command.

Predefined Properties of Templates

view = new dhtmlXDataView({
    container:"data_container",
    type:{
        template:"#Package# : #Version#<br/>#Maintainer#",
        css:"some",
        width:120,
        height:40,
        margin:5,
        padding:0,
    }
});

template - (string) the template definition
height - (number) the item height. The default value - 115;
width - (number) the item width. The default value - 210;
margin - (number) the item margin. The default value - 0;
padding - (number) the item padding. The default value - 0;
border - (number) sets the border of the item container. The default value - 1;
css - (string) allows applying an additional css class to the template (see details below). The default value - 'default'.

Styling of Templates

If you want apply a custom CSS style to the template, use the following technique:

Set the css property of the type parameter to some value, for example 'custom'

view = new dhtmlXDataView({
    container:"data_container",
    type:{
        template:"#Package# : #Version#<br/>#Maintainer#",
        css:"custom",
    }
});

Define 2 css classes on the page with the following names (use the !important declaration to guarantee that the defined css property will be surely applied):

.dhx_dataview_[css]_item - applied to items in the unselected state
.dhx_dataview_[css]_item_selected - applied to items in the selected state

.dhx_dataview_custom_item_selected{
    font-weight:bold !important;
}
.dhx_dataview_custom_item{
    font-size:12px !important;
}

Note, the css property has the default value - 'default'. So, you can skip step 1 and define the css classes with the following names:

.dhx_dataview_default_item - applied to items in the unselected state
.dhx_dataview_default_item_selected - applied to items in the selected state

Special Templates

In addition to a standard template, dataview can have additional task-specific templates defined:

template_edit - applied to items during the Items editing process
template_loading - used as a stub during the Dynamic loading of data from the server

view = new dhtmlXDataView({
    container:"data_container",
    edit:true,
    type:{
        template:"#Package# : #Version#<br/>#Maintainer#",
        template_edit:"<input class='dhx_item_editor' bind='obj.Package'>",
        template_loading:"Loading..."
    }
});
