LazReport heading
« on: March 02, 2018, 02:39:09 pm »
Hi

In a LazReport pageheader I want a text from an TEdit component visible on screen. From LazReport tutorial I see

      procedure TForm1.Button1Click(Sender:TObject);
      begin
        frReport1.Values.FindVariable('test').Field := QuotedStr('test1');
        frReport1.ShowReport;
     end;

The .lrf file is loaded, I have created the variable 'test' in category 'myown' in frReport1. 'test' is connected to values [None] in variables editor. Variable 'test' is placed  in band on canvas together with a label.

I expected to see 'test1' printed when clikcing Button1, but only the label are printed.

I have removed the master data band at this stage.

Is there an explanation to the poor result. >:(

Start a new application drop an frReport on the form, set its property StoreInForm to true in the object inspector, open the designer and drop a report title band, in that band drop a rectangle object and start its editor, in the memo editor type [Test1], close the editor and the report designer. Drop a button on the form and double click it to autocreate  the click event add the code below.
Code: Pascal  [Select]
  1. procedure TForm1.Button1Click(Sender :TObject);
  2. begin
  3.   frVariables.Variable['Test1'] := 'This is a test' ;
  4.   frReport1.ShowReport;
  5. end;
  6.  
save and execute your application, press the button. The first time the code is executed the variable will be auto inserted, the consequent clicks will only change its value.
