Memo component
Basic Memo
MemoEdit is used to create multiline text input (text-area).
<MemoEdit Rows="5" />
Usage
With bind attribute
By using bind-*
attribute the text will be automatically assigned to the member variable.
<MemoEdit @bind-Text="@description" />
@code{
string description;
}
With event
When using the event TextChanged
, you also must define the Text
value attribute.
<MemoEdit Text="@description" TextChanged="@OnDescriptionChanged" />
@code{
string description;
void OnDescriptionChanged( string value )
{
description = value;
}
}
Settings
Text Changed mode
By default the TextChanged
event will be raised on every keypress. To override default behavior of TextChanged
event and to disable the change on every keypress you must set the ChangeTextOnKeyPress
to false
on application start. After setting it to false
the event will be raised only after the input loses focus.
public void ConfigureServices( IServiceCollection services )
{
services
.AddBlazorise( options =>
{
options.ChangeTextOnKeyPress = false;
} );
}
Text Delay mode
Because of some limitations in Blazor, sometimes there can be problems when ChangeTextOnKeyPress
is enabled. Basically if you try to type too fast into the text field the caret can jump randomly from current selection to the end of the text. To prevent that behaviour you need to enable DelayTextOnKeyPress
. Once enabled it will slightly delay every value entered into the field to allow the Blazor engine to do it’s thing. By default this option is disabled.
public void ConfigureServices( IServiceCollection services )
{
services
.AddBlazorise( options =>
{
options.DelayTextOnKeyPress = true;
options.DelayTextOnKeyPressInterval = 300;
} );
}
Note: All of the options above can also be defined on each MemoEdit
individually. Defining them on MemoEdit
will override any global settings.
