Grid - Performance - too slow.

Dear Alex,
I am using demoversion to check whether it suits our site or not.
I m facing some problems, please help me to sort it out.

I used virtual mode - false. but still page rendering is very slow. it taking 5 to 10 mins to display the data of 700 rows and 10 columns, having one column with HyperLink.

more over IE showing following warning message___

"A script on this page is causing Internet Explorer to run slowly, if it continues to run your computer may become unresponsive.

Do you want to abort the script?
Yes No
"
MY PC Cong.
Intel P4 2.00 GHz

PF Usages: 507 MB
for 3 mins.

Please Help me regarding this performance issue.

Ashish,

I'm a different Alex from the one you are addressing, but I'm guessing I may have a clue as to why the grid is slow. Virtual mode needs to be turned on for grid to be faster, so you set it to true not false.

>> I used virtual mode - false.

You should keep virtual mode = true for the large datasets. Switching off virtual mode is only suitable for the small grids (less than 100 rows).

Hey ALEX,

THANKS BOTH OF U....
BUT STILL I M FACING SAME PROBLEM... EVEN AFTER ALTERING THE VERTUAL MODE BETWEEN "TRUE" AND "FALSE".....

STILL IT TAKING SAME TINE [~2 MINS] TO LOAD DATA IN GRID...

IF U CAN SPARE SOME TIME AND TRY MY CASE, U MAY FOUND MY MISTAKE WHICH CAUSING THIS PROBLEM

u can try the explample taking 700 rows and 9 cols and following data...

>> Code goes here <<

<span id="grid1"></span>

>> Break <<

>> Javascript Code <<

function onpenNewWinCompIPO(cLink,cTitle)
{
window.open(cLink,cTitle,'scrollbars=yes,resizable=yes,top=150,left=150,width=430,height=320')
}

var grRowNum;
grRowNum = 0;
var grid1 = new AW.UI.Grid;
grid1.setId("grid1");
grid1.setColumnCount(9);
grid1.setHeaderText("Date", 0);
grid1.setHeaderText("Reference No", 1);
grid1.setHeaderText("Exch.", 2);
grid1.setHeaderText("Bank", 3);
grid1.setHeaderText("Cheque", 4);
grid1.setHeaderText("Description", 5);
grid1.setHeaderText("Debit", 6);
grid1.setHeaderText("Credit", 7);
grid1.setHeaderText("Balance", 8);
//grid1.setCellText("Cell");
grid1.setHeaderHeight(20); // header height - 40px


>> Code Break <<

>> Code: Continue <<
grid1.addRow(grRowNum);
grRowNum++;
grid1.setCellData("04/04/2007",0,grRowNum);
grid1.setCellData("DR/003/---92 ",1,grRowNum);
grid1.setCellLink("javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')",1,grRowNum);
grid1.setCellTemplate(new AW.Templates.Link,1,grRowNum);
grid1.setCellData(" ",2,grRowNum);
grid1.setCellData(" ",3,grRowNum);
grid1.setCellData("By Bill DR/003/---92 for Ex: BSE,- BT: DEPOSITORY - Settlement=2007003,,",4,grRowNum);
grid1.setCellData("",6,grRowNum);
grid1.setCellData("1,590,957.99",7,grRowNum);
grid1.setCellData("2,871,224.47&nbsp;Cr",8,grRowNum);


>> break <<

like this 700 rows having one cell a link opning a popup.

and at last some more code .....

>> Code: Continue <<

grid1.setVirtualMode(false);
//grid1.clearSortModel();
//grid1.onHeaderClicked = function(){return true};
//grid1.getHeaderTemplate().refresh();
grid1.refresh();
//object.write(grid1);

>> end <<


NOW IF U CAN TRY THIS U CAN FIND IT TAKING TIME.... PLEASE SUGGEST ME IF U CAN TRACK OUT THE PROLEM......

THAKNS ONCE AGAIN RESPONDING ME.....

i m sorry alex,

please try this code at last....

>> Code: Continue <<

grid1.setVirtualMode(true);
//grid1.clearSortModel();
//grid1.onHeaderClicked = function(){return true};
//grid1.getHeaderTemplate().refresh();
grid1.refresh();
//object.write(grid1);

>> end <<

thanks

Ashish,

Does your application structure allow you to load the data as a javascript array as illustrated by:

/grid.examples/asp-adodb.html

I think it could be faster since it runs on the server and sends the completed data to the browser for processing by AW.

Thanks Alex,

as u said I tried with the arrays, its really incredibly fast.
but as I need
OnClick - some PopUp should open
or applying different styles to columns as per need of data
or changing font color in individual CELL as per data; like credit amount should appear in GREEN and debit amount should appear RED...

such Cell Level scripting i not able to perform with arrays...

in previous code i used OnClick on 2nd column.

but now code which i m giving is like what u said in ur replay...

correction:

1) change

grid1.setCellTemplate(new AW.Templates.Link,1);

to

grid.setCellTemplate(new AW.Templates.Link,1);

2) change

cellUrl = cellUrl & "grid1.setCellLink(""javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')"",1," & rowCount & ");" & vbCrLf

to

PLEASE FIND BUG IN MY CODE AND LET ME KNOW....

WARM REGARDS,
ASHISH DHANORKAR.
Ashish Dhanorkar [Ashida001@gmail.com]

Ashish,

The problem seems to be with the row ids. This line:

grid.setCellLink("javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')",1,0);

attempts to assign the url to the first row by calling it row 0. This is the bug since the row is called "4/1/2007" as indicated by the myRowIDs array. This means that the cell link should be assigned with the following kind of reference:

grid.setCellLink("javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')",1,"4/1/2007");

In order to produce this kind of code, the ASP code I sent earlier needs to be modified such that the line:

cellUrl = cellUrl & "grid.setCellLink(""javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')"",1," & rowCount & ");" & vbCrLf

changes to:

cellUrl = cellUrl & "grid.setCellLink(""javascript:onpenNewWinCompIPO('bill.asp?title=Bill%20Details&e=ALL&b=2007003&v=BSE &cc=60366 &brc=RT &r=DR/003/---92 &d=4/4/2007&da=0&cam=1590957.99&cn=VIRESH P SHAH ','Comp')"",1," & quote & rsq.Fields("Date") & quote & ");" & vbCrLf
