Hi All

I went through the forum for the above topic, I found many entries, but I have some specific question on this dynamic data loading. Here is my HTML Code.

}
window.onload = Form_Load;
=====================================================
I want to populate the data returned by the GetXMLData function, which in turn calls a ASP page using HTTPRequest.
The data returned by HTTPRequest in a array with delimiter "|". I split it in the js file and taking the first element aND assignign to the row count.
The second element in the array is the data, which is returned in the following format.
["12345","3/16/2006","ABC","This is test","1","DealerQuote","3/16/2006","Quoted"].
and assigned to the listdata variable.

Now my question is how do I set the data to the grid.
"objRepair.setDataProperty("text",function(i,j){return listdata[i][j]});"
The above statement is returning an error "listdata[...] is null or not an object".

I will appreciate if some one in this forum can help solving the problem. I am struggling to get the basic grid working for more than a week.

Thanks in advance

It looks like the row count does not match the number of rows in array for some reason. Could you add try/catch into the data function (function(i,j){return listdata[i][j]}) and check values for i, j when there is an error?

Hi Alex

As you mentioned, problem is with the row count. I tried to just return one row, but the problem is, where do I create the array.
Whether on the server side program or in the js file.
The data returned from the server looks like this
[["12286", "3/8/2006", "Gunline Tools", "Customer will send closer after replacement ships. A=17-22/32, F=flush b1=1.6125. Wants 16001 also\r\nNardini TT1030", "1", "RLNoNDealerQuoteNew.rpt", "3/8/2006", "New", ], ]

When I assign the data to the variable listdata, I get the same error "listdata[...] is null or not an object".

Can you help me fix this problem.

Thanks

Some suggestions -

- remove the comma after your last array element

- try listdata = sdata[1]; instead of [sdata[1]]

- put error check inside data text function

function textfunc(i, j){
try {
return listdata[i][j];
}
catch(err){
alert("error, i=" + i + " listdata.length=" + listdata.length);
}
}

objRepair.setDataProperty("text", textfunc);

Hi Alex

I followed your suggestions and made the changes. I removed the square brackets from sdata[1] and inserted the function textfunc,
the textfunc is returning an error
"error i=0 listdata.length=256" and the grid column is filled with word
"undefined"

Any further help will be appreciated.

Thanks
