Advantages/Disadvantages Of Public Shared Functions

Jan 8, 2010

We have an application that has quite an extensive APP_Code directory (about 150 functions). The functions are split across multiple files and then classes and namespaces.

On numerous pages we have to create numerous instances of the classes to be able to access the functionality, which can get very repetitive and means we're repeating code on every page declaring the instance etc.

As far as I can tell, a way to navigate this issue, is to make the functions Public Shared (as opposed to just Public functions).

Forms Data Controls :: Databinding A Dropdownlist Within A Gridview?

Mar 29, 2010

I have a gridview in which I have two drop downs. One is populated with values that are static, so I have a regular sub that does that in the code behind. I tried to add code for databinding the other ddl to a datatable. I cannot get this to work. It just comes up empty. My asp code is fine, and the datatable definately has data in it - just nothing gets populated.

One other thing - the code for the static ddl has worked fine, but when I add this other block (either to the same sub as that, or dow the rowdatabound event) the static one doesn't work either.

Forms Data Controls :: Databinding With Templated Used Control?

Jan 27, 2010

I've created a templated user control by following the example on the microsoft support pages. I won't post it all but the important part of the CS file looks as follows:

[Code]....

I'm not sure if the whole _CurrentDataItem business is required, I don't think so.The problem I've got, is that I've tried nesting it inside a FormView control so I can use it to display a record from a database. My ASPX looks like this:

[Code]....

Now, the bound properties (TitleText and TitleSubText) bind correctly, but the nested / template content is blank when the page loads. I'm not sure if this is something to do with the order in which everything is loaded or because I'm missing some code in the SimpleTemplate to get it to bind (etc.).

Forms Data Controls :: FormsView DataBinding In Code Behind?

Sep 26, 2010

I have a forms view with an EditItemTemplate. I would like to populate the EditItemTemplate using the code behind vs. mixing the data in the UI as so:

text='<%#Bind("Question") %>'

At what point do I do this? I thought it would be on FormView_DataBinding, but there is no e.item.dataitem like other databound controls. My issue is that I need to check criteria of the data prior so I know which inputs to make visible, to set properties of controls within the EditItemTemplate, and manipulate the data prior to binding (less of an issue as I can always just tweak the data prior to binding, but it doesn't solve my other problems).

Forms Data Controls :: Changing Data In A Gridview During Databinding Or After Databound?

Feb 2, 2010

im building a simple message messenger web application, i currently have a column in my database dedicated to the status of a message. Its bound to the third column in a datagrid.

After converting the column to a TemplateField and using a Label to fetch the data how do i change the text from the database to a small message, e.g. if the data in the database (as an interger) is 0. how do i change the interger to a string to display "UnRead". Do i need to do this during the databinding call or after the grid has been databound?

I know it would be easier to use a boolean and checkbox control but the interger column represents more values than true or false.
