Ich habe versucht, einen HTML-Text von einigen, wo etwa 10 Strings zusammen mit mit in einer Datagrigd-Spalte verkettet. Ich kann es aber nicht auf die Größe der Zelle übertragen. Ich versuche, dies in eine HBox einzubetten und dann in die Zelle zu legen. Aber ich bin nicht in der Lage, die Größe der Zelle zu ändern, da ich sehe, dass die HBox schrumpft, obwohl in der Zelle genug Platz ist. Kann mir jemand helfen, diese HBox an die Größe der Datagrid-Zelle anzupassen?Datagrid item rendering
Ich habe versucht mit UpdateDisplayList(), aber es wird in Endlosschleife und der Bildschirm wird einfrieren. Bitte finden Sie den Code unten.
Unten ist die Klasse Iam einen Aufruf an den Renderer. Kann jemand bitte helfen Sie mir aus.
