Appearance
In this article, you will find information about the styling options and rendering of the Telerik UI for ASP.NET Core ComboBox.
For a live example, visit the Appearance Demo of the ComboBox.
Options
The ComboBox supports the following styling options:
-
Size—configures the overall size of the component. -
Rounded—configures the border radius of the component. -
FillMode—configures how the color is applied to the component.
Size
The Size option controls the size of the ComboBox. The k-input-{size} class, which is applied to the wrapping span element of the ComboBox, reflects the value of the Size option.
The following values are available for the Size option:
-
Small—small size (applies thek-input-smclass to the wrapping span element) -
Medium—medium size (applies thek-input-mdclass to the wrapping span element) -
Large—large size (applies thek-input-lgclass to the wrapping span element) -
None—unset.
The following example demonstrates how to set Size in the declaration of the ComboBox:
@(Html.Kendo().ComboBox()
.Name("combobox")
.Size(ComponentSize.Medium)
.DataTextField("Text")
.DataValueField("Value")
.Filter("startswith")
.HtmlAttributes(new { style = "width:100%;" })
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item 1", Value = "1"
},
new SelectListItem() {
Text = "Item 2", Value = "2"
},
new SelectListItem() {
Text = "Item 3", Value = "3"
}
})
)
@{
var items = new List<SelectListItem>()
{
new SelectListItem()
{
Text = "Item 1", Value = "1"
},
new SelectListItem()
{
Text = "Item 2", Value = "2"
},
new SelectListItem()
{
Text = "Item 3", Value = "3"
}
};
}
<kendo-combobox name="combobox"
size="ComponentSize.Medium"
datatextfield="Text"
datavaluefield="Value"
filter="FilterType.StartsWith"
bind-to="items">
</kendo-combobox>
The default Size value is Medium and it is applied to the wrapping span element through the k-input-md class.
<span class="k-combobox k-input k-input-md">
</span>
Rounded
The Rounded option controls the border radius of the ComboBox. The class that corresponds to the Rounded option is k-rounded-{rounded}.
The following values are available for the Rounded option:
-
Small—small border radius (applies thek-rounded-smclass to the wrapping span element) -
Medium—medium border radius (applies thek-rounded-mdclass to the wrapping span element) -
Large—large border radius (applies thek-rounded-lgclass to the wrapping span element) -
Full—largest border radius (applies thek-rounded-fullclass to the wrapping span element) -
None—unset.
The following example demonstrates how to set Rounded in the declaration of the ComboBox:
@(Html.Kendo().ComboBox()
.Name("combobox")
.Rounded(Rounded.Medium)
.DataTextField("Text")
.DataValueField("Value")
.Filter("startswith")
.HtmlAttributes(new { style = "width:100%;" })
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item 1", Value = "1"
},
new SelectListItem() {
Text = "Item 2", Value = "2"
},
new SelectListItem() {
Text = "Item 3", Value = "3"
}
})
)
@{
var items = new List<SelectListItem>()
{
new SelectListItem()
{
Text = "Item 1", Value = "1"
},
new SelectListItem()
{
Text = "Item 2", Value = "2"
},
new SelectListItem()
{
Text = "Item 3", Value = "3"
}
};
}
<kendo-combobox name="combobox"
rounded="Rounded.Medium"
datatextfield="Text"
datavaluefield="Value"
filter="FilterType.StartsWith"
bind-to="items">
</kendo-combobox>
The default Rounded value is Medium and it is applied to the wrapping span element through the k-rounded-md class.
<span class="k-combobox k-input k-rounded-md">
</span>
FillMode
The FillMode option controls the way color is applied to the rendered ComboBox. The k-input-{fillMode} class, which is applied to the wrapping span element of the ComboBox, reflects the value of the FillMode option.
The following values are available for the FillMode option:
-
Solid—applies thek-input-solidclass to the wrapping span element -
Flat—applies thek-input-flatclass to the wrapping span element -
Outline—applies thek-input-outlineclass to the wrapping span element -
None—unset.
The following example demonstrates how to set FillMode in the declaration of the ComboBox:
@(Html.Kendo().ComboBox()
.Name("combobox")
.FillMode(FillMode.Solid)
.DataTextField("Text")
.DataValueField("Value")
.Filter("startswith")
.HtmlAttributes(new { style = "width:100%;" })
.BindTo(new List<SelectListItem>()
{
new SelectListItem() {
Text = "Item 1", Value = "1"
},
new SelectListItem() {
Text = "Item 2", Value = "2"
},
new SelectListItem() {
Text = "Item 3", Value = "3"
}
})
)
@{
var items = new List<SelectListItem>()
{
new SelectListItem()
{
Text = "Item 1", Value = "1"
},
new SelectListItem()
{
Text = "Item 2", Value = "2"
},
new SelectListItem()
{
Text = "Item 3", Value = "3"
}
};
}
<kendo-combobox name="combobox"
fill-mode="FillMode.Solid"
datatextfield="Text"
datavaluefield="Value"
filter="FilterType.StartsWith"
bind-to="items">
</kendo-combobox>
The default FillMode value is Solid and it is applied to the wrapping span element through the k-input-solid class.
<span class="k-combobox k-input k-input-outline">
</span>
Rendering
Starting with version R1 2022, the component has a new rendering. For additional information on the decision behind these changes, visit the Components Rendering Overview article.
To review the latest rendering of the component, refer to the HTML specifications in the Kendo UI Themes Monorepo. The tests folder of the repository contains the rendering for all flavors of the components, providing a clear reference for how their elements are structured. The rendering information can help you customize a component's appearance and behavior by applying custom CSS or JavaScript to suit specific design or functional requirements.
