Column custom Value Render

[wohral]

Is there any way, how to make custom rendering of value in grid. For example I would like to render text field, and put the icon in front of text.

$someTextColumn->setCustomValueRender(function($item) {
    return "<i class='icon'>".$item->getValue()."</i>";
});

Something like used in Ubladoo datagrid for Nette https://ublaboo.org/datagrid/column#renderer

Or I have to specify my custom Type? and define custom class and block?

You have to specify your own custom column type and its rendering. In this case you can extend TextColumn, use a different column type name

public function getType()
{
    return 'class_icon';
}

and put the html part into render
