Classe: TButtonColumn  - X-Ref

TButtonColumn class

TButtonColumn contains a user-defined command button, such as Add or Remove,
that corresponds with each row in the column.

The caption of the buttons in the column is determined by {@link setText Text}
and {@link setDataTextField DataTextField} properties. If both are present,
the latter takes precedence. The {@link setDataTextField DataTextField} property
refers to the name of the field in datasource whose value will be used as the button caption.
If {@link setDataTextFormatString DataTextFormatString} is not empty,
the value will be formatted before rendering.

The buttons in the column can be set to display as hyperlinks or push buttons
by setting the {@link setButtonType ButtonType} property.
The {@link setCommandName CommandName} will assign its value to
all button's <b>CommandName</b> property. The datagrid will capture
the command event where you can write event handlers based on different command names.
The buttons' <b>CausesValidation</b> and <b>ValidationGroup</b> property values
are determined by the column's corresponding properties.

The buttons in the column can be accessed by one of the following two methods:
<code>
$datagridItem->ButtonColumnID->Button
$datagridItem->ButtonColumnID->Controls[0]
</code>
The second method is possible because the button control created within the
datagrid cell is the first child.
