Since you just want a grid solution maybe something like this would work?

;with StateData as

(

select t1.*, ROW_NUMBER() over(partition by t1.STATE order by t1.city) as RowNum

from #tempCityState t1

join #tempCityState t2 on t1.STATE = t2.STATE and t1.City <> t2.City

group by t1.STATE, t1.CITY

)

select case RowNum when 1 then STATE else '' end as STATE, City

from StateData

order by StateData.State, City

I still say it would be better in the front end but this does what I think you are after.

this gives a layout similar to what am looking however it does not group rows . the row concactenation has been lost: its not what am looking for . Tks anyway

Then I would go back to my previous position that this belongs in the front end. I don't think you need to use Item Templates for this though. I tossed together a really quick page that does just what you are looking for.

First your proc needs to be tweaked slightly.

create proc RowsDisplayed as

if object_id('tempdb..#tempCityState') is not null

drop table #tempCityState

Create TABLE #tempCityState (State Varchar(5), City Varchar(50))

Insert Into #tempCityState

Select 'CO', 'Denver' Union

Select 'CO', 'Teluride' Union

Select 'CO', 'Vail' Union

Select 'CO', 'Aspen' Union

Select 'CA', 'Los Anggeles' Union

Select 'CA', 'Hanford' Union

Select 'CA', 'Fremont' Union

Select 'AK', 'Wynne' Union

Select 'AK', 'Nashville'

Select Distinct State, (Select Stuff((Select City + '

'

From #tempCityState

Where State = t.State

FOR Xml Path(''),TYPE).value('.','VARCHAR(1000)'),1,0,'')) AS Cities

From #tempCityState t

Now in your .net page you just need to add a grid. The HTML section looks like this.

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">

<Columns>

<asp:BoundField DataField="State" HeaderText="State">

<ItemStyle VerticalAlign="Top" />

</asp:BoundField>

<asp:BoundField DataField="Cities" HeaderText="Cities" HtmlEncode="False" />

</Columns>

</asp:GridView>

Notice that the Cities column has HtmlEncode = False. That means it will render any html as html instead of encoding it first.

So to complete this I just created the following snippet in Page_Load:

using (SqlConnection connection = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString))

{

string sql = "RowsDisplayed";

SqlCommand command = new SqlCommand(sql, connection);

command.CommandType = CommandType.StoredProcedure;

connection.Open();

SqlDataReader dr = command.ExecuteReader();

GridView1.DataSource = dr;

GridView1.DataBind();

connection.Close();

}

The output looks like this:

Used the htmlencode = false but it didn't change nothing . please note i do already have a gridview.databind() code in my page load(). i was also unable to download the attachment: the link is taking me to the forum home page. In the latest tsql code that you provided i would appreciate if you can combine the first two lines togheter as not sure whether i got them copied correctly. have them as follow:

Select Distinct State, (Select Stuff((Select City + ''

Still believe i will have to use templatefield as a workaround even do i would prefer a boundfield which gives more flexibility in term of sorting and filtering

julesbenone SSChasing Mays Points: 601 More actions · Answer 6

based on your various recommendations i finally found a good workable solution without having to compromise that much with my early tsql code in the views. i stayed with my first tqsl as follow:

Stuff

(

Select ',' + City As [text()]

From #tempCityState

Where State = t.State

For Xml Path('')

)

, 1, 1, ''

) As Cities,

Please note this is part of a view that is used in a stored procedure that feeds an asp.net gridview

i made this adjustment in my stored procedures:

Replace(ViewName.Cities, ',' , '

') AS Cities

then after i added the HtmlEncode="False" property recommended by Sean in the BoundField.

by using this solution i didn't have to review rows concactenation tsql code(s) i have in several views and as a result affect others sto proc and frontends that connect to my sql server database.

To conclude i resolved my formatting problem by adding one additional property in my gridview boundfield and slightly adjusted a specific stored procedure that is only used by the asp.net application

Thanks to all who have contributed in this thread ... i think the topic can be closed now .. happy week end

This code is a modification to the above post to have the cities adjusted under each other

Create TABLE #tempCityState (State Varchar(5), City Varchar(50))

Insert Into #tempCityState

Select 'CO', 'Denver' Union

Select 'CO', 'Teluride' Union

Select 'CO', 'Vail' Union

Select 'CO', 'Aspen' Union

Select 'CA', 'Los Anggeles' Union

Select 'CA', 'Hanford' Union

Select 'CA', 'Fremont' Union

Select 'AK', 'Wynne' Union

Select 'AK', 'Nashville';

with States as (

select distinct

State

from

#tempCityState

)

select

State,

stuff((select CHAR(9) + ' ' + City + char(13) + char(10)

from #tempCityState tcs

where tcs.State = States.State

order by tcs.City

for xml path(''),TYPE).value('.','varchar(max)'), 1, 3, '') as Cities

from

States;

Drop table #tempCityState
