I am new to the whole MVP thing and slowly getting my head around it all. The a problem I am having is how to stay consistent with the MVP methodology when populating GridViews (and ddls, but we will tackle that later).
Is it okay to have it connected straight to an ObjectDataSourceID? To me this seems wrong because it bypasses all the separation of concerns MVP was made to do.
So, with that said, how do I do it? How do I handle sorting (do I send over handler events to the presentation layer, if so how does that look in code)? Right now I have a GridView that has no sorting. Code below.

I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?

I have a database containing a table with about 700,000 images so I recently enabled Filestream. However, I can't figure out how to render the images.
I have an Imagefield control within a Detailsview which is using an .aspx file to render the image through the DataImageUrlFormatString (which is typical). In my select statements I tried changing the binary field containing the image from objectdata to objectdata.PathName() per the Microsoft documentation but this does not work. I get the red X image box.

I have a ListView which is filled by generic list of type MyClass. I can easily bind data from this list into ListView. But I have problems with reading data in opposite direction. This is my class:
[Code]....
I have also generic list of type MyClass:
[Code]....
Finally I bind data to ListView this way:
[Code]....
My ListView template:
[Code]....
How can I read data from ListView into my List list?
The operation of reading ListView data into List generic list should begin after clicking the button "GetData".
I saw the following advice:
[Code]....
but it does not work - the DataItem property of each Item of ListView has null value. The point is that I have generic list with data. I am binding this data into ListView which can be edited by user. After that after click Save or GetData data from ListView is read into generic list of MyClass type.

I am new to asp.net. I need to send a value from send.html to get.aspx.cs
In send.html, I have
<a href="<%=var%>">The Link</a>
where the value of var is anotherPage.html
how do I get the value of var from send.html when send.html calls get.aspx?
Many hours spent still can't figure out. I probably could make the url like get.aspx?link=<%=var%>.... and then use Request.QueryString["link"] in get.aspx.cs to retrieve it, but shouldn't there be an easier way to look up the variable in send.html?
