title: How to customize DBAdvGrid Columns in order to display data from database?
body: <p>I am trying to display data from database table into DBAdvGrid so that first column will show only checkbox, while other 3 columns will show label, description and image field from database table. 
  I am using UniConnection, UniQuery, UniDatasource components to display data. I am setting UniConnection Database properties via code as I can give relative path of the database rather than full path. At object inspector it accepts only fiull path of database.</p>
  
  <p>My code is as follows
  At FormCreate event</p>
  
  <pre><code>  filepath1 := ExtractFilePath(Application.ExeName);
    UniConnection1.Database := filepath1+'empdata.s3db';
    UniConnection1.Connected := True;
    UniQuery1.SQL.Text := 'Select '', label, description, image from emp';
    UniQuery1.Open;
  
    DBAdvGrid1.Columns[0].FieldName := '';
    DBAdvGrid1.Columns[2].FieldName := 'label';
    DBAdvGrid1.Columns[3].FieldName := 'description';
    DBAdvGrid1.Columns[4].FieldName := 'image';
  </code></pre>
  
  <p>The above code connect and display data successfully but problem is with displaying data at DBAdvGrid as I want first column to display only checkbox (no data from DB). At DBAdvGrid I cannot set field name of particular column through object inspector as it is connecting to the database through code with by extracting path.</p>
  
  <p>I have set first column of <code>DBAdvGrid</code> editor type property to the <code>edDataCheckBox</code> so that it would display checkbox in first column but it is getting overlapped by label data, similarly at second column it is showing 'description' and at 3rd column image.</p>
  
  <p>How to customize it via code so that it would show </p>
  
  <pre><code>1st column - No Data
  2nd column - label
  3rd column - description
  4th column - image
  </code></pre>
  
  <p>What I am getting as</p>
  
  <pre><code>1st column - label overlapped with checkbox
  2nd column - description
  3rd column - image {MEMO}
  4th column - 
  </code></pre>
  
  <p>How to sort out this problem ?</p>
