Dove posso trovare i modelli XAML per un DataGrid WPF?

Question

Desidero modificare il modello per Microsoft WPF DataGrid (versione 4.0) ma non sono sicuro di come sia il modello esistente. Qualcuno sa cosa sia o dove potrei trovarlo?

Answer 1

Consiglio di andare in Blend (se lo avete) e l'estrazione del modello. Altrimenti, puoi ottenere XAML usando XAMLWriter.

Questo unfortunately named page (non penso che questo sia davvero "roba per bambini", vero?) Ha un esempio di fare entrambe queste cose.

Nel caso in cui la pagina non capita di andare via (il 2009 è abbastanza lontano nello specchietto retrovisore):

// Get the template from the control 
ControlTemplate template = ctl.Template; 

// We want our xaml of be properly indented, ohterwise 
// we would not be able to indent them. 
XmlWriterSettings xmlSettings = new XmlWriterSettings(); 
xmlSettings.Indent = true; 

// Make the string builder 
StringBuilder sb = new StringBuilder(); 
XmlWriter writer = XmlWriter.Create(sb, xmlSettings); 
XamlWriter.Save(template, writer); 


// Now the sb.ToString() should give us the template 

Tutto il merito per Shafqat Ahmed.

Ecco come fare a livello di codice:

Answer 3

ci sono due grandi liste di modelli/stili su MSDN che uso spesso:

http://msdn.microsoft.com/en-us/library/aa970773.aspx

purtroppo, non sono come pubblicizzato come dovrebbero essere ...

quindi, per quanto ti riguarda, ti consiglierei questo (ottenuto dal secondo link): http://msdn.microsoft.com/en-us/library/ff506248.aspx

Ecco quello che ho ottenuto fuori Blend 4:
