TreeGrid

Is there any update in this? Is it possible to addRowData with the any of current releases? I am not able to edit cell content as well in the tree grid. Any clue?

Thanks,

Also looking for an update. Is it possible to insert and edit tree nodes?

The isNodeLoaded function does not appear to be returning the correct value for a node that has not been loaded yet. The debugger shows the value for rc[isLeaf] as 'false' and the number of node children is zero. The current implementation checks that rc[isLeaf] is defined, not that it has a particular value. So it seems the method will always return true (unless rc.loaded is defined, but I don't see that set anywhere in the tree grid code).

should the statement:

} else if ( rc[isLeaf] || $(t).jqGrid(“getNodeChildren”, rc).length > 0) {

instead be:

} else if ( (rc[isLeaf] == “true” || $($t).jqGrid(“getNodeChildren”, rc) > 0) {

Or maybe I am misunderstanding something…Thanks, Toby

Is there a reason that the multiselect and altRows settings get forcibly disabled? I can sorta get why altRows would be disabled (it probably would require doing a complete traversal of the table every time you open/close a node). But I can't understand why multiselect is disabled.

If nothing else, this should probably be documented, along with the other things that are forced off in this mode?

When there is a child node that belongs to two or more parent nodes, treegrid doesn't work properly. In other words:

+ A (parent_group_id)

+ C  (child_group_id)
  + 1 (member_id)
  + 2 (member_id)
  + 3 (member_id)
+ D  (child_group_id)
+ E  (child_group_id)

+ B (parent_group_id)

+ C  (child_group_id)
  + 1 (member_id)
  + 2 (member_id)
  + 3 (member_id)
+ F  (child_group_id)
+ G  (child_group_id)

We didn't want to have duplicated group in our system. Therefore we made code to share common sub groups such as C. However, under this situation, treegrid seems to be malfunction. Is there any advice?

HI, I want to display the folder structure of a drive of system. First I show all the drives available and than when user clicks on the Drive node, it will display folders inside it.

Is there a way I can pass the nodeid to the server where nodeid should be the folder/drive name what user clicked on?

Can we have pager enabled with treeGrid (by any hack or something).

How to extended all node when treegrid loading？

  gridComplete: function(){
	    setTimeout(function(){	   
	       rootNode = $( "#youGridObject" ).jqGrid('getRowData')[0];
	       rootNode._id_ = rootNode.id;
	       $( "#youGridObject" ).jqGrid('expandRow'   ,rootNode);
	       $( "#youGridObject" ).jqGrid('expandNode'  ,rootNode);	
	       $( "#youGridObject" ).jqGrid('setSelection',rootNode.id);       
	    }, 10);

}

In your demo example of treeview, you have 'id' as a key column but if i change that column to any other column by adding colmodel as { name: 'id1', index: 'id1', width: 1, hidden: true, key: true } then it gives me error Cannot read property 'rowIndex' of undefined. In my application i want all nodes exapanded by default. for that i have added exapnded:true and loaded:true values in data.

It is possible that some way to get a list of open items in the tree?

how can i catch the parent_id when i am adding it is not post does anyone has an idea??

We are currently having a difficult time trying to auto expand a jqGrid treegrid to the 3rd level of the tree so that all children are visible. The current data set is thousands or rows deep and we were forced to dynamically load each node when requested to be expanded, which requires reloading the grid. Expanded node ids are saved in an array as a saved tree state so that the nodes can be re-expanded when the tree is redisplayed. This goes through the process of loading each node from the database as the expansion happens. AS each node is dynamically loaded and expended gridComplete and loadComplete events are handled as expected.

We are trying to trigger the 3rd level expansion by utilizing the save tree state and the existing logic to break out the tree appropriately within the existing logic. The problem we are experiencing is that the tree cannot expand out fast enough in order to be processed, and we can never break the tree apart completely.

Here is the function to iterate through the parents to capture the appropriate ids to expand:

function ExpandGridLevel(level) { if (ExpandGridLevels == false) { ExpandTotalLevels = level; ExpandLevelCurrent = 0; ExpandGridLevels = true; } if (!TreeExpandState) { TreeExpandState = new Array(); } $(”.treeclick”, ”#Grid”).each(function () { if ($(this).hasClass(“tree-plus”)) { var id = $(this).parents(“tr”).attr(“id”); var rowLevel = $(”#MaGrid”).getLocalRow(id); if (rowLevel.level == ExpandLevelCurrent) { TreeExpandState.push(id); $(this).removeClass(“tree-plus”); $(this).addClass(“tree-minus”); } } }); $(this).trigger(“reloadGrid”); $(”#Grid”).jqGrid(“setGridParam”, { datatype: “local” }); ExpandLevelCurrent++; RefreshGrid(); }

Our gridComplete and loadComplete sections of code:

loadComplete: function (data) { $(”#Grid”).jqGrid(“setGridParam”, { datatype: “local” }); if (TreeExpandState.length == 0) { setTimeout(function () { ExpandGridLevel (ExpandTotalLevels); }, 3000); } }

gridComplete: function () { if (TreeExpandState) { var rowId = TreeExpandState.shift(); ExpandNode(rowId); } }

Is what we are trying to do possible with jqGrid? If so, how do we know when the tree expansion is truly complete and we can reiterate over the expended grid to begin the expansion of the next level of parents?

In case someone needs this, If you have a treegrid with checkboxes, but only need the last leaf to have the checkbox control, you can easily empty the parent cells by using the gridComplete function and the first td ( which has the IsLeaf column )

gridComplete:function(){

var r = $(this).find("tr td:first-child");
r.each(function (index, instance) {
          var _td = $(instance);
          if(_td.text()==='false') {
               _td.siblings().find('input').each(function (sindex, sinstance) {
               $(sinstance).parent().empty();
           });
     }
});

}

ExpandColumn not work with rownumbers:true
