TUniDBGrid - Grouping - Text of group-header

[erich.wanker]

HI,

in a table - i have a lot of persons - and 50% are in different categories - 50% are in no category  (must be a empty database field !!)

i use TUniDBGrid - Grouping with Fieldname "category-Name" and FieldCapture "Category-Name" 

Works fine ! :-)

BUT: I want change the caption of group header to "Persons without Categories" if the "category-Name" is empty ???

 

Actual i have a uniDBGrid like this

+   Category-Name:                                                               <- here are all Records without Category 
+   Category-Name:  FisteCategoryDescription
+   Category-Name:  SecondCategoryDescription  
+   Category-Name:  and so on ...

 

I want a uniDBGrid like this

+   Persons without Categories  
+   Category-Name:  FisteCategoryDescription
+   Category-Name:  SecondCategoryDescription  
+   Category-Name:  and so on ...

 

ThanX

Erich

I already explained that in one of my videos :-)

WOW .. THANX a lot :-) ... works perfect !!!!

 

i stored it in "onFrameCreate" and search the right index number 

gruppenname_id:='0';
cnt := Mydbgrid.Columns.Count;
        for colIdx := 0 to cnt - 1 do
          begin
            if Mydbgrid.Columns[colIdx].FieldName = 'gruppenname' then gruppenname_id:= inttostr(colIdx);
          end;


Mydbgrid.ClientEvents.UniEvents.Add('beforeInit=function beforeInit(sender, config)'+
'{ '+
' config.groupingFeature = Ext.create('+#39+'Ext.grid.feature.Grouping'+#39+',{ '+
'   groupHeaderTpl:new Ext.XTemplate('+#39+'{[this.getGroupTitle(values.rows[0])]}'+#39+','+
'    { '+
'      getGroupTitle: function(values) {'+
'             if(values.data['+gruppenname_id+']=='+#39+''+#39+')'+
'              return '+#39+'All the ungroupt Things are here :-) '+#39+';'+
'            else '+
'              return '+#39+'Gruppenname: '+#39+'+values.data['+gruppenname_id+']; '+
'        } '+
'     })'+
'  });'+
'  config.features= [config.groupingFeature]; '+
' } ');
