Hi,

I have a problme with the treegrid that really baffles me.

Some context:

I have a grid with a custom formatter, and a switch to change this grid to a treegrid (with a .GridUnload method)

this is some code:

Hello Stefan,

Nothing wrong here.

The limitation is that the level field is not accesable during this operations. To explain better. Level field is the last field (if I remember right) and is provided as last in the data.

Example if you have field1, field2, field3,..

then if you format the data of field2 you have acces to field1 and field2, but not to field3, since this field is not yet fetched from the grid.

To resolve the problem

1. You can use afterInsertRow event to add a link, where all the row info is available

2. We can use some tricky way to do this, but my question is in wich format is your data – xml or json? The idea is to use named conventions in the data, wehre you provide the level element before the info element.

Hope this helps

Regards

Tony

ah, I see.

I'm using JSON, and my data is like this:

{"total":"1","rows":[{"level":"0","isLeaf":"false","expanded":"false","description":" group description" ,"name":"groupname01","parent":"null","id":"groupname01"},{"level":"1","isLeaf":"true","expanded":"true" ,"name":"name02","parent":"groupname01","id":"name02"} ....

So the level is sent first.

I don't have “info” in my JSON, this is an extra column in the view, that I map to the name (with jsonmap:”name”) because i need that to construct the url.

So I think i have everything for option 2, or do i need to do something else? I'm not sure I understand “named conventions”, do you mean i need to explicitly define in my jsonReader to use “level”?

Thanks already,

Stefan

Hello Stefan,

This is what I mean.

“I'm not sure I understand “named conventions”, “

sorry I mean data is provided as name:value i.e. the way that you do.

Please let me known if the option 2 work.

Regards

sorry i took some time to answer, i had to deliver the application.

In the end we decided to remove the treegrid from this applicatoin, due to performance issues: i have a tree with 2 root elements and each one has about 400-500 children. it loads quickly, but closing the folder (to hide the children) it took about 8 sec's!

Anyhow, back to the original problem:

I've tried it like this:

colNames:['level','Id','Name','Description','info'],
