How can i achieve these requirements?

Question

<p>We have a reporting requirements where:<br />1. Number of different reports are more than 300<br />2. User should have flexibility to select coulumns what s/he wants<br />3. Page width is constant i.e. if number of columns width is greater than page width, report should auto wrap</p><p>We are using the following approach to create dynamic reports.</p><p>1. Reports are getting created with prtDoc...</p><p><br />2. Then in a for loop (i.e. based on number of columns user has chosen..</p><p><br />  2.1 add a field..<br />  <br />  2.2 set top,let,width,height for each field<br />  <br /> <br /> The follwoing is snippent of the code</p><p>                                <br /> <br />dtlSection= (Section) rptDoc.getReportDefController().getReportDefinition().getDetailArea().getSections().getSection(0);</p><p>fldTop =10;<br />fldLeft = 5;<br />for(int i=0;i<columnName.length;i++){<br />                                if(filedLeft>=pagewidth){<br />     dtlSection=getNewDetailsSection();<br />     fldLeft= 5;<br />     fldTop =10 + fldHeight;// add field height ..<br />                                <br />                                }<br />  DBField oDBField = new DBField();<br />  oDBField.setName(field_name);//field_name is name of the column<br />  oDBField.setType(oFieldValueType);//data type of that column<br />  FieldObject oFieldObject = new FieldObject();<br />  oFieldObject.setDataSource(oDBField.getFormulaForm());<br />  oFieldObject.setFieldValueType(oDBField.getType());<br />  IndentAndSpacingFormat indentSpacing = new IndentAndSpacingFormat();<br />  IStringFieldFormat stringFieldFormat = oFieldObject.getFieldFormat().getStringFormat();<br />  stringFieldFormat.setIndentAndSpacingFormat(indentSpacing);<br />  oFieldObject.getFieldFormat().setStringFormat(stringFieldFormat);<br />  rptDoc.getReportDefController().getReportObjectController().add(oFieldObject, oSection, -1);  <br />  add_db_field(dtlSection,oTable.getName()"."columnName<i>,fldValueType,javaDataType,fldLeft,fldTop, fldWidth,fldHeight);<br />  fldLeft = fldLeft+fldWidth;</p><p>}</p><p><br />Our question is</p><p>1. Is there any way by which auto wrapping of page width is taken care? (instead of manually done as shown in the program)<br />   <br />   For each column, we are calculating max width and storing into database. This value is supplied based on the report column type</p>

Answer 1

It should work if you select the following when setting up password security:
Changes Allowed: Filling in form fields and signing existing signature fields
Enable copying of text, images, and other content: [Checked]
To allow for digital signing you will need to set up one or more signature fields.
