Re[2]: Unable to access "Choices" in DotCMIS 0.7
Thank you, Florian!
The problem was that I needed to cast the property definition I was
looking for to "IPropertyStringDefinition" before I could see the choice
list.
Here is the corrected, working code (in C# - VB.Net will work exactly
the same):
private void getChoiceList(string docClassName, string propName)
{
logMsg("Querying TypeDefinition(" + docClassName + ")...");
ITypeDefinition docClassDef =
m_session.GetTypeDefinition(docClassName);
logMsg("Searching for PropertyDefinition(" + propName +
")...");
IPropertyDefinition propDef = null;
foreach (IPropertyDefinition pd in
docClassDef.PropertyDefinitions)
{
if (pd.Id.Equals(propName))
{
propDef = pd;
break;
}
}
logMsg("Choices:");
IPropertyStringDefinition stringPropDef =
(IPropertyStringDefinition)propDef;
int i = 0;
foreach (IChoice<string> ch in stringPropDef.Choices)
{
logMsg(" ch[" + i + "]: " + ch.DisplayName + "=" +
ch.Value);
i++;
}
}
- Output =>
11/27/15 13:00:09 Querying TypeDefinition(RGBClass2)...
11/27/15 13:00:09 Searching for PropertyDefinition(RGBChoiceList)...
11/27/15 13:00:10 Choices:
11/27/15 13:00:10 ch[0]:
Joe=System.Collections.Generic.List`1[System.String]
11/27/15 13:00:10 ch[1]:
Dan=System.Collections.Generic.List`1[System.String]
11/27/15 13:00:10 ch[2]:
Paul=System.Collections.Generic.List`1[System.String]
Problem solved - thank you!
