Hi all
I have a grid I use in tree grid
Everything works well, expect when the grid gets a nice chunk of data it gets slower…
I can handle that however, what I would like to do is when someone opens the page with the grid, it tells them on the screen somewhere to please wait…
Once the grid goes to show on the screen, the please wait message would go away and the data would be loaded.
concept is easy, just not sure of the approach with dhtmlx software. I can’t use frames etc to check for session updates etc to process it so something native to your software would be ideal
Thanks in advance on this

I have tried adding but I don’t see it being shown before the grid data
Below is where I added it to my JS file …
I have made it bold etc for easier viewing…

function buildGrid(){
//set grid parameters
mygrid.selMultiRows = true;
mygrid.setImagePath("…/…/images/grid/");
var flds = “<img src=”/modules/messages/images/paperclip.gif">,<img src="/modules/messages/images/items.gif">,From,Subject,Received";
mygrid.setHeader(flds);
mygrid.setInitWidths(“15,20,150,*,180”)
mygrid.setColAlign(“left,left,left,left,left”)
mygrid.setColTypes(“ed,ed,ed,ed,ed”);
mygrid.setColSorting(“str,str,str,str,str”)
mygrid.setColumnColor("#ffffff,#ffffff,#ffffff,#ffffff,#ffffff")
mygrid.enableDragAndDrop(false);
mygrid.enableEditEvents(false,false,false,false,false); //Disables doubleclick edit ability in grid
//start grid
mygrid.init();
mygrid.attachEvent(“onXLS”,function(){
//show loading message here
document.write(“testing”);
})
mygrid.attachEvent(“onXLE”,function(){
//hide loading message here
})
mygrid.loadXML("…/…/modules/messages/gridxml.php");
mygrid.treeToGridElement = function(treeObj,treeNodeId,gridRowId){
return [0,treeObj.getItemText(treeNodeId)];
}
//redefine grid-to-tree drop element
mygrid.gridToTreeElement = function(treeObj,treeNodeId,gridRowId){
return this.cells(gridRowId,1).getValue()+""+this.cells(gridRowId,2).getValue();
}
mygrid.rowToDragElement = function (id){
if(this.cells(id,2).getValue()!="")
return this.cells(id,2).getValue()+""+this.cells(id,1).getValue();
return this.cells(id,1).getValue();
}
document.write is not the best technique here, the method will be called after document rendered so result of such operation is not predictable, more safe approach - use already existing container. Loading …
mygrid.attachEvent(“onXLS”,function(){
document.getElementById(‘message’).style.display=‘block’;
})
mygrid.attachEvent(“onXLE”,function(){
document.getElementById(‘message’).style.display=‘block’;
})
