Add checkbox in the table on the client-side

danielvc

Hi Allan,

I am using this amazing webcomponent, and I already did a donation and I want to do that every month.. Thank you very much for this component.

Brother, I'm having a problem when I try to use the datatable on the following way. I want to render a checkbox in each row of the datatable... I know how to do that, but not in my way. For example... the datatable receives from the server the data... at total, are 6 columns, but, my datatable has 7 columns... the last one column (7) is specific to put the checkbox.

my table:
"[code]


NFS-e
Data de Emiss

UPEngineer

What I would do for this is return the 7th row from the Server.

Don't know what your server code looks like but just output the with it.

At least that is how I do it.

Hi UP!

I could do that.. for example.. in my server side I have:

[code]
foreach (DataRow item in dt.Rows)
{
alNotas.Add(new string[7] {item["NUNUMERO"].ToString(),
item["DTCOMPETENCIA"].ToString(),
item["STTOM_NOME"].ToString(),
item["VLTOTALLIQUIDO"].ToString(),
item["VLTOTALISS"].ToString(),
item["VLDEDUCOES"].ToString(),
"Nothing"
});
}
return new JsonResult { Data = new { aaData = alNotas } };
[/code]

well.. where is written "nothing", it shouldn't exist..I should return just 6 fields, not 7, so, in the the 7th column would be created dinamically (with the checkbox).

I could do to return insted of "nothing"... return "", however, I wouldn't like to return a html element from my business layer.

If my donation ins't important for a answer.. ok, I stop to give donations

First of all - you can , as mentioned return "".
If you realy don't want to mix business layer with presentation - just return "" or "0"/"1" (If you want to know if the checkbox should be on from the get go) in the seventh col, and in client side handle that - just like you did.

It is not realy mixing business layer with presentation because the checbox is part of your BL - I guess it is not there only for viewing - it is in some way part of your BL.
