Syntax

public class SfComboBox<TValue, TItem> : SfDropDownList<TValue, TItem>, IInputBase, IDropDowns, IVirtualList<TItem>

Type Parameters

Name	Description
TValue	The type of the value selected or entered in the ComboBox.
TItem	The type of items displayed in the ComboBox dropdown list.

Remarks

The ComboBox extends DropDownList and provides additional features such as custom value input, autofill, and filtering capabilities. Use TValue for the value type and TItem for the data type of items in the dropdown list.

Examples

<SfComboBox TValue="string" TItem="string" DataSource="@MyList" AllowCustom="true" Autofill="true">
    <ComboBoxEvents TValue="string" TItem="string" ValueChange="@OnValueChange" />
</SfComboBox>
@code {
    protected List<string> MyList = new List<string> { "Apple", "Banana", "Orange" };
    private void OnValueChange(ChangeEventArgs<string, string> args)
    {
        // Handle value change
    }
}

Constructors

SfComboBox()

Declaration

public SfComboBox()

Properties

AllowCustom

Gets or sets a value indicating whether the ComboBox allows users to enter custom values not present in the data source.

Declaration

public bool AllowCustom { get; set; }

Property Value

Type	Description
System.Boolean	A boolean where `true` allows users to enter custom values; otherwise, `false`. The default value is `true`.

Remarks

When set to true, users can type a value that does not exist in the data source, and the CustomValueSpecifier event is triggered to handle the custom value. If set to false, only predefined values from the data source can be selected.

Examples

<SfComboBox TValue="string" TItem="string" AllowCustom="true" DataSource="@MyList">
    <ComboBoxEvents TValue="string" TItem="string" CustomValueSpecifier="@OnCustomValue" />
</SfComboBox>
@code {
    protected List<string> MyList = new List<string> { "Apple", "Banana", "Orange" };
    private void OnCustomValue(CustomValueSpecifierEventArgs<string> args)
    {
        args.Item = args.Text;
    }
}

Autofill

Gets or sets a value indicating whether the ComboBox automatically fills the input with the first matched item while typing.

Declaration

public bool Autofill { get; set; }

Property Value

Type	Description
System.Boolean	A boolean where `true` enables autofill functionality; otherwise, `false`. The default value is `false`.

Remarks

When set to true, the ComboBox automatically completes the input with the first matching item from the data source as the user types. This enhances the user experience by suggesting relevant options dynamically.

Examples

<SfComboBox TValue="string" TItem="string" Autofill="true" DataSource="@MyList" />
@code {
    protected List<string> MyList = new List<string> { "Apple", "Banana", "Orange" };
}

IsClearButtonStopPropagation

Declaration

protected bool IsClearButtonStopPropagation { get; set; }

Property Value

Type
System.Boolean

ShowClearButton

Gets or sets a value indicating whether the ComboBox displays a clear button to reset the selected value.

Declaration

public override bool ShowClearButton { get; set; }

Property Value

Type	Description
System.Boolean	A boolean where `true` displays the clear button; otherwise, `false`. The default value is `true`.

Overrides

Syncfusion.Blazor.DropDowns.SfDropDownList<TValue, TItem>.ShowClearButton

Remarks

When the clear button is clicked, the Value and Index properties are reset to null, allowing users to easily clear the current selection and start anew. This feature enhances usability by providing a quick way to reset the input.

Examples

<SfComboBox TValue="string" TItem="string" ShowClearButton="true" DataSource="@MyList" />
@code {
    protected List<string> MyList = new List<string> { "Apple", "Banana", "Orange" };
}

ValidateOnInput

Gets or sets a value indicating whether the ComboBox performs validation on input changes.

Declaration

public bool ValidateOnInput { get; set; }

Property Value

Type	Description
System.Boolean	A boolean where `true` enables validation on input; otherwise, `false`. The default value is `false`.

Remarks

When set to true, the ComboBox validates the input as the user types and updates the model value. The ValueChange event is triggered after the component loses focus, allowing for form validation or further processing of the input value.

Examples

<SfComboBox TValue="string" TItem="string" ValidateOnInput="true" DataSource="@MyList">
    <ComboBoxEvents TValue="string" TItem="string" ValueChange="@OnValueChange" />
</SfComboBox>
@code {
    protected List<string> MyList = new List<string> { "Apple", "Banana", "Orange" };
    private void OnValueChange(ChangeEventArgs<string, string> args)
    {
        // Handle value change
    }
}

Methods

BuildRenderTree(RenderTreeBuilder)

Declaration

protected override void BuildRenderTree(RenderTreeBuilder __builder)

Parameters

Type	Name	Description
Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder	__builder

Overrides

Syncfusion.Blazor.DropDowns.SfDropDownList<TValue, TItem>.BuildRenderTree(Microsoft.AspNetCore.Components.Rendering.RenderTreeBuilder)

IsCustomValue()

Declaration

protected override bool IsCustomValue()

Returns

Type
System.Boolean

Overrides

Syncfusion.Blazor.DropDowns.SfDropDownList<TValue, TItem>.IsCustomValue()

UpdateChildProperties(Object)

Updates the ComboBox field settings based on the provided field value.

Declaration

public override void UpdateChildProperties(object fieldValue)

Parameters

Type	Name	Description
System.Object	fieldValue	The ComboBoxFieldSettings object containing field mappings for the ComboBox.

Overrides

Syncfusion.Blazor.DropDowns.SfDropDownList<TValue, TItem>.UpdateChildProperties(System.Object)

Remarks

This method updates the Fields property with the provided fieldValue properties, such as GroupBy, Text, and Value, and applies them to the ComboBox for data binding.
