Can a DataList HeaderTemplate bound Items from the DataSource? 1

[Alcar]

Greetings all,

I am using a DataList to recreate an order form. I have some Header information and then the Order Details. I am trying to DataBind the Header information in the HeaderTemplate and I get no result. (no errors either)

Eg:

<aspataList id=&quot;dlOrders&quot; runat=&quot;server&quot; Width=&quot;100%&quot;>
<HeaderTemplate>
<asp:Label ID=&quot;lblOrderNumber&quot; Runat=&quot;server&quot;><%# DataBinder.Eval(Container.DataItem, &quot;OrderNumber&quot.ToString()%></asp:Label>
</HeaderTemplate>

and I get absolutely nothing. ANYHOO... I was wondering if I could work around this...
Or should I just re-think my datasource structure...

Jelly-beans for helpers =)

Try it without the .ToString and see if it will just display the number.

BRAVO btw! You've correctly spelled ANYHOO!

No, the header doesn't work like that... since the databinding is, in effect, a loop -- a vertical one at that.

If you need to adjust the appearance of your header, use the onItemDataBound event, and tell him:

if e.item.itemType = listItemType.Header then
e.item.cells(0).text = &quot;header1&quot;
e.item.cells(1).text = &quot;header2&quot;
'and so on
end if

Anywho, I hope that helps! ;-)

Paul is at the top of the list here and it shows he spells anyWHO right.

Paul I looked thru some of my old code and what I did is probably massively innefficient but.. I used the databinder for the headers.


<HeaderTemplate>
<asp:Label id=Label1 runat=&quot;server&quot; Text='<%# DataBinder.Eval(DataSet11, &quot;Tables[Employees].DefaultView.[0].EmployeeID&quot %>'>
</asp:Label>
</HeaderTemplate>


I didn't specify the Container which is what the list is bound to but used the dataset itself instead.
Just thought I would add that to the pile That'l do donkey, that'l do

Extremely interesting Mark. What index is passed to choose the right Dataview? Is it the same as the DataSetIndex passed by the datalist events?
Eg:

DataList_DoEdit(Object sender, DataGridCommandEventArgs e)
{
int dsIndex = (int)e.Item.DataSetIndex;
}

Not sure I understand the question. Or what I was doing when I wrote that actually.

This only works when the table only has one row or when a column is the exact same throughout as it would be for an id in a details section for example.

I use the HTML view as little as possible, VS doesn't seem to like it much.
When I put this together I added a label to the header section of the datalist and then hit the databinding button. From there I just chose the options I wanted.

In the page_load event I made sure the datalist I was using was filled... and the villagers danced!

Not sure if I cleared anything up on that let me know. That'l do donkey, that'l do

Here it is:

System.Data.DataRowView DataView[int recordIndex]

It returns a DataRowView that you can access through the recordIndex (equal to the DataSetIndex).

Et voila'!

So if we have a DataSet that filles the DataList, we can access it through the:

<%# DataBinder.Eval(DataSetID, &quot;Tables[TableName].DefaultView.[recordIndex].FieldName&quot %>

Thanks Mark!
