HI,

The VCL community lacks a decent Gantt chart component, the best one with professional looking is from EzPlan-It but it's data source accepts only TDataSet which I don't want. So I am considering implement a Gantt chart with the custom draw support of next grid. Is NextGrid capable of doing this? Any tips of implement this? Thank you.

Edwin.

Hello Edwin,

If you like to implement gant chart inside cell this may be done with using OnCustomDrawCell event (http://dn.bergsoft.n...in-nextgrid.htm).

If you like I may help you with implementation, and maybe include column type with Gannt chart.

Best regards

boki,

in fact i'v not yet get to the implementation stage, rather i am just want to get things be ready upfront. can the mouse events nextgrid exposed support implementing drag and drop? also the column headers must be able to be switched between week,month and year.

boki, i.d suggest you implement it base on nextgrid, not to difficult for you i think. i am sure will buy it, i can event preorder it if you can give the timeframe. may be you can have a survey for potential requirements in borland newsgroup.

Hello,

I think that I have one small sample created with NextGrid. I will try to find it and give it to you to check it.

Hello Boki,

I have been waiting for your example for weeks, have you found it already? Many thanks

Hello Edwin,

I didn't succeed to find it I am sorry for giving false hope. But I will like to help you with your implementation.

You may do a much with custom sorting. For example cell may contain start time, length etc. of project but drawing to been made custom. I will send you small example tomorow.

Best regards
