Hi,
Sorry about that but i dont know about the GridView.
You can use the cells collection of the row -
r.Row.Cells(0) where the '0' is column number of your desired column.
I am not sure about it but you can atleast try !

check this -

Hi Blur Member ....

u may use ," e.Row.Cells[index].Text " to get the value on that Particular Cell ( index th position, zero indexing) of the current row.

Hope It works..

Jay

if (e.Row.Cells[3].Text == "P")

put '==' operator for comparision

Basically I have a dropdownlist which filter adminNo and then display each record at the gridview. So user can see how many P exists in column Category for each adminNo.

the result display at the footer is 0.

i hope it is not due to me filtering records by dropdownlist.

jay thanks

Whether it works or not ? You need to declare the variable 'presentCount' as a 'static' variable inorder to retain its value during the Gridview is population.

Jay

I hope my declaration is correct.

public static int presentCount = 0;

But yet the footer still show 0.

Believe me it works fine... I think , ur data "P" came from database. It may have some white spaces. use Trim() method to remove that, then the string comparision works properly.

Hope it help u...

static int count = 0;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string tmp=(e.Row.Cells[3].Text).Trim();

if (tmp == "P")
{
count += 1;
}
}

if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[3].Text = count.ToString();
}
}

When the user click from the ListBox to view each adminNo, the Show Footer manage to calculate the number of P exist in the gridview.

But when the user click another adminNo, the Show Footer number was accumulated with the previous Show Footer.

Example:
when the user click for the first time
Show Footer: 18
second output when user click for the second time, the number of P exist in the gridview is suppose to be 10, but show 38 instead
Show Footer: 38

thanks in advance. Much appreciated.

i think the static variable 'showCount' keeps its old value. So you may declare it properly , in such a way that when u click a item from ur ListBox , the variable is set to zero.

hope it helps u

Try out this !.............

int presentCount = 0;
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
   YourType  obj =  e.Row.DataItem as YourType;
  if ( obj.Property = "P")
	presentCount++;
}
else if (e.Row.RowType == DataControlRowType.Footer)
{
e.Row.Cells[3].Text = presentCount.ToString();
}
}
