Inline editing uden gridview.

Jeg er igang med at arbejde på et mindre skoleprojekt i form af en chat.

Jeg har lavet chatrums administration, så der kan laves både kategorier og rum i de kategorier.

Det jeg godt kunne bruge nu er den funktionalitet der er i GridView med når der klikkes på edit. Altså, at der bliver sat tekstbokse ind i den række der skal redigeres i stedet for at det bliver lavet i eget panel et andet sted.

Koden ser ud som følger. Jeg har på nuværende tidspunkt lavet paneler der bliver visible når jeg klikker på Edit uden for en hvilken som helst række, men den skal som sagt gerne ind i den rigtige række.
