I am working on this problem a couple of days, I did not get solution.

in my web page , there is a gridview with a checkbox templatefield
I need to know if checkbox is checked, I use following way, Even though I saw the checkbox is checked, I get checkbox.check is false.

<asp:gridview id="GridView1" runat="server" datakeynames="empid" cellpadding="4" forecolor="#333333" gridlines="None" width="335px">

<columns>

<asp:templatefield>
<headertemplate> <asp:checkbox id="chkall" runat="server">
<itemtemplate>
<asp:checkbox id="chk" runat="server">

protected void Button1_Click(object sender, EventArgs e)
{
string EmpId="";
//bool chkBox=false ;

foreach (GridViewRow row in GridView1.Rows)
//for(int row=0;row<gridview1.rows.count;row++)
{
="" checkbox="" cb="((CheckBox)row.FindControl("chk"));
"
="" if="" (cb="" !="null" &&="" cb.checked)
="" if(cb.checked="=true)
" chkbox="true" ;
="" empid="GridView1.DataKeys[row.RowIndex].Value.ToString();
" label1="" .text="" +="string.Format(
" "this="" would="" have="" deleted="" {0}<br="">", EmpId);

}
}

For this kind of value you have to use ' or " to enclose the Value

Ex// 1,'john,store',aroda

Hi Chetan,
This did not work when I read "1,'john,store',aroda" from file and split it on comma to convert to a datatable, "john" and "store" are coming in different columns. I want this in same column.

Well you're not operating on this as a CSV (which would honour the quotes as a text identifier) - you're simply splitting the string using comma:

string[] columns = rows[j].Split(',');

If you want to roll your own code to read from a CSV then you'll need to build something into this line above that honours quotes as a text identifier.

I suppose u first split your string by ' and then split it by comma. Hope it works.

for (int j = 0; j < rows.Length; j++)
{
string[] columns = rows[j].Split(',');
if (dtCustomer.Columns.Count == columns.Length)
{
dtCustomer.Rows.Add(columns);
}
}

change your code like this

arrTemp[]=rows[j].Split("'")
you get three parts

1,'abc,def',asd
as 1,
abc,def
,asd
now

add this like this

for (int j = 0; j < rows.Length; j++)
{
arrTemp[]=rows[j].Split("'")
dtCustomer.Rows.Add(arrTemp[0].subString(1,arrTemp[0].Length-1);
dtCustomer.Rows.Add(arrTemp[1]);
dtCustomer.Rows.Add(arrTemp[2].subString(2);
}

Maximum total file size for upload in a form

Hello everyone,

This is developed in .Net 2.0 (ASP .NET with VB .NET as code)

In a page, I have 9 fields for user to upload files. I have just encountered a situation where I choose a file for all the fields (that means 9 files), and when the total sum of file size (of the 9 files) exceeds a certain amount, the next page that I see after I click on submit is "Page cannot be displayed".

When I choose the 9 files with smaller size, the system works just fine.

Do you have any idea if there is such a limitation on the file size to be uploaded in a form? If there is, what is the size?

Appreciate your help.

Thanks,
Yenyen

That's becuase you are going beyond default maximum size that request can have you need to make it more in Web.config
httpRuntime maxRequestLength="100000" add this in system.web tag
