In jqgrid treegrid, how can I specify that I want to load the entire tree up front versus on demand?

If I understand your question correct, the most important lines of the Tree Grid code to answer on your question you will find here and here . I can describe the code fragment so: if the user try to expand a node it will be examined the contain of the hidden column 'loaded' of the node. You can post the contain of 'loaded' column together with the JSON/XML row data.

If the 'loaded' column contains false (or the 'loaded' is not set by the server) the parameters nodeid parentid and n_level will be set and the tree grid will be reloaded.

I think you do this with a combination of the adjacency model that is specified, and altering your response so it responds with ALL the data in ALL the nodes.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
