Example of Master/Detail

First, I'm sorry.

For some time I'm trying to make an example of master / detail with ZQuery / DataSetProvider / ClientDataSet, but I'm not getting.

I followed the fixed of bugs 43 and 59, but even then still having problems.

Does someone can give me a example, please?

I also got the example in the bug 43...

Someone??

My small project is stopped because of this problem.

Will it be that I will have to change the structure?

Thanks for all..

Diego.

Hi acakadut.

Thanks for the example.

But isn't working fine. Try to delete or to insert a new record in detail, you'll get a error similar to: "ClientDataSet1: Dataset not in edit or insert mode".

hi diegocm,

yeah... you'll see that message because the button1 click event is post & applyupdate on clientdataset1 and clientdataset1 datastate not in dsEdit or dsInsert.

u must change clientdataset1 datastate to dsedit / dsinsert before edit or insert in detail, because the button1 click event is posting the clienstdataset1 & applyupdate or u can enabled / disabled the button.

btw... i forget to put Clientdataset2.applyupdates(-1) in button1 click event, to posting clientdataset2, before posting and update make it sure the dataset state is on dsedit / dsinsert.

it's all depend on how u want to make the code...

hope can help u...
