Forms Data Controls :: Gridview Non-visible Values Always Go To Null?

Jun 24, 2010

Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?

Forms Data Controls :: Making A Row Of A Designated Column Clickable To See The Details In Another Page?

Apr 10, 2010

I have a GridView which is linked to the database via SqlDataSource.

What I would like to do is to make each row of a designated column clickable. Once the user has clicked on a row, the application should postback to another page to allow the user to read all the details of that row.

The effect should be as we can see in this post: if you go to "mypost", you have a list of posts and then when you click on one of them you are able to see the details of that.

I read lots of posts that are using, however, other methods such as datalist + dataset controls etc.

Forms Data Controls :: Access Value Of Column In Selected Row In Gridview

Nov 9, 2010

I have seen a lot of things on the net on this but nothing seems to work. I have a GridView with name and other information on files stored in a database but also on a Server. I display the gridview with the files and the user selects the file to delete (row) by hitting the command field for Delete. I have an event on the gridview for code behind. Here I want to access the file name for the row selected, to be able to include it in the File.Delete statement.

Even before this I want to display the selected file name in a label back to the web page. I have tried everything including findcontrol selectedValue, etc. Nothing is working. I either get complier error, or nothing is displayed in label. If I let it go the the File.Delete step I get access error becasue there is no file name. HELP. here is screen shot of the gridview. Ignore the download button for now. That is my next headache to figure out. So based on the screen shot I want the value of log_doc from the gridview. It is in a column called file_name

File ID
File Name

I'm currently working on a small project and therefore created a gridview, including one bit column which has been linked with a checkbox in both the itemtemplate as the edititemtemplate (autopostback = true).Databinding for these two checkboxes has been linked (two-way) to the bit column.Now I want to display the gridview to end-users.
