Displaying the Column Headers

This example demonstrates how to display the column headers.

Code sample

1. WebGridHeaders colHeaders = reportGrid.getColumnHeaders();

2. for (int i=0; i < colHeaders.size(); i++){

3. WebHeaders colElements = colHeaders.get(i);

4. for (int j=0; j < colElements.size(); j++){

5. WebHeader colElement = colElements.get(j);

6. int colSpan = colElement.getColSpan();

7. int rowSpan = colElement.getRowSpan();

8. int depth = colElement.getDepth();

9. WebElement webElement = colElement.getWebElement();

// using the attributes, generate the HTML to display them.

…HTML code…

10. }

11. }

Explanation

Line 1 gets the column headers from the WebReportGrid object. Lines 2-8 iterate through all the WebHeader objects. Line 9 gets the WebElement object that provides information about the elementID and the name of the display. Line 9 onwards generates the HTML for displaying the grid using all the attributes obtained.
