Forms Data Controls :: Bind A Dropdownlist Which Is Present Only In The EditItemTemplate

Jun 15, 2010

I am handling the row databound event. I need to bind a dropdownlist which is present only in the EditItemTemplate.

So it is throwing:

DropDownList ddlAccountingPeriod = e.Row.FindControl("ddlAccountingPeriod") as DropDownList;

this throws a null exception as the dropdown is not present in the ItemTemplate.

Is there a way to check whether it is itemtemplate or edititemtemplate.

Forms Data Controls :: Use Eval Or Bind In A Databound Control?

Sep 8, 2010

I have a repeater I've databound with a generic arraylist from a LINQ query (.ToList() ) in the code behind.

I was using

<%# Bind("FirstName")%> but noticed
<%# Eval("FirstName")%> works just as well.

Is it better to use Eval or Bind? or does it depend on the situation?

Forms Data Controls :: Putting Radiobutton / Radiolist Inside Formview

Mar 4, 2010

I have been searching the net for quite a while and can't find an example of how to put a radiobutton or radiolist inside a formview. I have an objectdatasource that goes back to a table. One field in the table is Hydro -- which is an int field. There are three valid choices:

value Text
0 None
1 15 Amp Service
2 30 Amp Service

When I set my Formview to the objectdatasource my Hyrdo binding looks like this:


How would I change the above so that it would replace the TextBox with either a radiolist or 3 radiobuttons (I am ok with whichever is easier) so that it would look like this

Hydro: o None o 15 Amp o 30 Amp

Also, in the case of the update mode that the correct item is selected based on the value of 0, 1, 2 being read from the datatable

Forms Data Controls :: Using Custom Text Before Eval?

Mar 4, 2011

I have a repeater that has been given a datasource from my database containing pictures. The problem is that when i create and log a user into my site i send him to a folder that has no access from others than the ones with a roles called User. When he creates his profile, he uploads a picture which is saved in the same folder "User/picture/picturename" and in the database "picture/picturename".

Now i need to pull this picture to the Default page page where users are not logged in. If i add an Image Control to the frontpage with ImageUrl='<%#Eval ("PictureThumbURL") %>' it tries to pull out the picture from the folder User which is obvious that it can't since it lacks the User/ in front.

Is it possible to get this picture by manually adding User/ to the ImageUrl='<%#Eval ("PictureThumbURL") %>' and if so, how?
