Data range filter

Hi again,

#1
---------------------------------
I have a grid with a data type column. I want to create a filter for this column, using a double calendar. I want to have a function

myCal.rightCalendar.attachEvent("onClick", function(date){...});

and in this function I want to can create something in order to can apply a condition filter for my grid, something like

myCal.leftCalendar.getFormatedDate() < columnData < myCal.rightCalendar.getFormatedDate()

How can I do this? Is there any other posibility to do this?

This is not working:

mygrid.filterBy(3, '>'+myCal.leftCalendar.getFormatedDate());
mygrid.filterBy(3, '<'+myCal.rightCalendar.getFormatedDate(), true);



#2
---------------------------------
When I'll have the data range filter working, I want to attach a div and button

<div id='objId'></div><input type='button' id='bt' onClick='hide_show()' value='Show / Hide'/>

in my grid header, for a specific collumn. How can I do this?



#3
---------------------------------
I have this function:

    function hide_show() {
        myCal.isVisible () ? myCal.hide () : myCal.show ();
        }

which is called when I press the input button. My problem here is the div with double calendar is shown in top of my grid, and the grid is moved down. I want the functionality to be like this: when I press pe calendar botton, the calendar to be shown right there, in the data column header, above of my grid.


I hope all is clear, please give me some ideas.. Thanks in advance..

Thanks for your help.. BUT IT ISN'T ENOUGHT! We have a PRO dhtmlx version, and I'm very worried because I can't find in time all the information I need..

For example, I was looking very long time after seeing a method to know the column index using the column index. I didn't found this information in your documentation, but I found it in knowledge base.. I think this isn't so easy and normal.. Here I found this information:

http://dhtmlx.com/docs/products/kb/index.shtml?cat=search&page=5&q=6465&ssr=yes&s=column%20Index

please, tell me where can I find this information in documentation, not in knowledge base.. Please, give me a link..


About my problem with data range filter, I didn't find yet an answer for the issue #3.. So I'm still waiting for you to help me.. Please..

If dbl-calendar was initialized inside div, the show and hide methods will affect only visibility of calendar's container. If it has not position:absolute style defined - it will not be shown over grid, but will shift all content of the page.
