Repeater

[Peter Kirk]

Hi there

I have some c# code which extracts a list of data (an array of Port objects)
from a database, and I need to display this data on an asp, where the user
can see and edit the data (and press a "save" button to write changes back
to the database).

I am using a "repeater" to list the Port items on the page, where some of
the attributes of the Port objects are textboxes where the user can edit the
data.

My problem is the "save" button - for this I have an onclick handler, but
how does the list of Port objects get supplied to the onclick method so I
can write to the database?

Thanks for any help,
Peter

Peter,

The Save button is a single button and is not repeated, correct?

In the button's Click event, declare textbox variables that correspond to
the textboxes in each row of the repeater.

foreach(RepeaterItem rItem in rptRepeater.Items)
{
txtPort1 = (TextBox)rItem.FindControl("txtPortName");
txtPort2 = (TextBox)rItem.FindControl("txtPortPrice"); //Other
processing. }Where I've written 'other processing', you can take the
values in the textboxes, and save them back to the database. This will get
performed for each row of the repeater.

Peter,

The save button is in the "Footer" section of the repeater.
Do you know how I can stop the footer from being processed if the repeater
list is empty? For example, if there is no list then I don't want the save
button to be dsiplayed.

Thanks,
Peter

OK, I found out I can check <% if (myList.Items.Count > 0) ....
