Syntax to get the field names for a particular object, which changes dynamically?

hi,

 

I have displayed all the object names in a select list and while an object is selected, i am retrieving the object name and i have to select the field names for it. For this i found that the syntax as given below,

 

Schema.DescribeFieldResult f = Schema.sObjectType.Account.fields;

 

The Account object is hardcoded here, but, in my scenario, object name is dynamically changing, how to modify this syntax into dynamically changing one. any ideas or any other syntax's available to get field names?? 

Or is there any soql query to retrieve the field for the requested object? please provide any ideas or suggestions to retrieve the field names...

 

thanks,

abivenkat,

Hi abhivenkat,

public string object{get;set;}

Here object is dynamic value which object You selecting.

 

Schema.sObjectType sobject_type = object.getSObjectType();
Schema.DescribeSObjectResult sobject_describe = sobject_type.getDescribe();
Map<String, Schema.SObjectField> field_map = sobject_describe.fields.getMap(); 

 

Hope this will help you..!!!!!

 

Thanks

public virtual class Describe {

private Map<String, SObjectField> mapFields;

/** constructor */

}
public Describe(sobject obj) {
DSR = obj.GetSObjectType().getDescribe();
}


/**
get the field map.
Simliar to fields.getMap() but will cache the calls.
*/
public Map<String, SObjectField> fieldMap {
GET {
try {
if (mapFields==null)
mapFields=DSR.fields.getMap();
return mapFields;
}
catch(exception ex){ return null; }
}
}

Error: GridRep Compile Error: Method does not exist or incorrect signature: [String].getSObjectType()

Then how did you avoid this error?
