FlatColorPicker Events
This article describes the available events of the Telerik FlatColorPicker for Blazor.
OnChange
The OnChange event fires when the user commits their selection with:
- Apply or Cancel button click
- Enter keypress
Note that the OnChange event may also fire when the actual selected color has not changed.
The event type is EventCallback<object>. The OnChange event does not prevent two-way binding for the Value attribute.

<p>@EventLog</p>
<TelerikFlatColorPicker @bind-Value="@Color" OnChange="@FlatColorPickerOnChange" />
@code {
string Color { get; set; }
string EventLog { get; set; }
async Task FlatColorPickerOnChange(object newColor)
{
EventLog = string.Format("The selected color is: {0}", (string)newColor);
}
}ValueChanged
The ValueChanged event fires when the user selects a new color and the component value changes.
The event type is EventCallback<string>. Using ValueChanged requires one-way binding for the Value attribute and manual value update in the event handler.
@* Handle the FlatColorPicker ValueChanged event *@
<TelerikFlatColorPicker Value="@Color" ValueChanged="@FlatColorPickerValueChanged" />
@code {
string Color { get; set; }
async Task FlatColorPickerValueChanged(string newColor)
{
Color = newColor;
}
}ViewChanged
The ViewChanged event fires when the user toggles between the component views.
The event type is EventCallback<ColorPickerView>. Using ViewChanged requires one-way binding for the View attribute and manual value update in the event handler.
@* Handle the FlatColorPicker ViewChanged event *@
<TelerikFlatColorPicker @bind-Value="@Color" View="@View" ViewChanged="@FlatColorPickerViewChanged" />
@code {
string Color { get; set; }
ColorPickerView View { get; set; }
async Task FlatColorPickerViewChanged(ColorPickerView newView)
{
View = newView;
}
}
