2 Datagrid columns questions

[Mark B]

I have a Datagrid working fine, outputting:

Group
Most Popular Product Code
--------
-------------------------------

Earth.New Zealand
32
Earth.New Zealand
32
Earth.New Zealand.Aucklan d
32
Earth.New Zealand.Aucklan d
32
Earth.New Zealand.Aucklan d.Auckland
7
Earth.New Zealand.Aucklan d.Auckland.Parn ell
7
Earth.New Zealand.Aucklan d.Henderson
10024
Earth.New Zealand.Aucklan d.Henderson.New Account
10024
Earth.United States
32
Earth.United States.Texas
32


Now I want to do these 2 things:

1) Have clickable hyperlinks on each sub-group and not the periods e.g. for
the last entry above (Earth.United States.Texas):

<a href="http://www.mysite.com/showgroups/?GroupName=Eart h">Earth</a>.<a
href="http://www.mysite.com/showgroups/?GroupName=Eart h.United
States">United States</a>.<a
href="http://www.mysite.com/showgroups/?GroupName=Eart h.United
States.Texas">T exas</a>

I still want people to be able to sort the column as displayed though.


2) Rather than display the Most Popular Product Code (SQL int), I want the
result of the function fConvertCodeToP roductTitle(lng ProductID as Long) as
String. I still want people to be able to sort by the long integer value
though -- even though I don't want it displayed for the column.

How can I do this with the Datagrid control (Visual Web Developer 2008
Express)?

TIA

Hi

on item data bound change your output as you want...

RE: 2 Datagrid columns questions

Hi Mark,

For your scenario, since the string transforming logic is not that
simple(you need to format both the display string and the url string ), I
think you'd better write a helper function in codebehind and call this
function to perform transform in your databinding control.

Here is a test function I've written which accept an input string and
transform it to output html hyperlinks:

=============== ============
protected void Page_Load(objec t sender, EventArgs e)
{
string ret =parse_string(" Earth.New Zealand.Aucklan d.Henderson.New
Account");

Response.Write( "<br/>" + ret);
}

string parse_string(st ring input)
{
const string stmp = "<a
href='http://www.mysite.com/showgroups/?GroupName={1}' >{0}</a>";


string[] items1 = input.Split('.' );
string[] items2 = new string[items1.Length];

for (int i = 0; i < items1.Length; ++i)
{
items2[i] =string.Join(". ", items1, 0, i + 1);
}


StringBuilder sb = new StringBuilder() ;
sb.AppendFormat (stmp, items1[0], items2[0]);

for (int i = 1; i < items1.Length; ++i)
{
sb.Append("."); sb.AppendFormat (stmp, items1[i], items2[i]);
}
return sb.ToString();

}
=============== ==========

You can call this funcction in your databinding control to format the
certain data field (string value).

Hope this helps.

Steven Cheng
