Forms Data Controls :: Displaying A Null Or Empty Cell For A Null Datetime Database Value In Gridview?

Dec 6, 2010

I have setup my business object to have a create_date and edit_date members both datetime datatypes. My company want to display the create_date and edit_date fields in a gridview for each transaction. The problem i have is that after insterting a record it will have a valid create_date but no edit_date and when displayed in the gridview it defaults to datetime.minvalue (My default). How on earth do i show an empty field in my gridview for a null datetime field in the database?

I am using similar architecture to the Imar Spaanjaars example of a tiered solution. With a few small tweeks it has worked well for me for ages. I am passing a List<Database> to my object datasource which connects to my gridview.

Forms Data Controls :: Detailsview Mode Updates Read Only Field To Null Or Empty

Sep 10, 2010

I have a detailsview on my page binding a table with information about the employees. They can update their information. Some info should be visible but not updateable. I could change the update command not updating but I like the control where I can set the column to read only. In that way the employee will find the data visible and they will see that the field/column cannot be changed. But having the column read only will return a null-value into that column when editing and updating anything. Why is that? Shouldn't it just update it's read only value?

Forms Data Controls :: Preventing The Display Of Titles For Data Fields If The Data Field Is Empty In ListView?

Nov 14, 2010

I have a listview control bound to an SqlDataSource. As part of the formatting I want to add a title to the data returned from my database. For instance if the data base returns a phone number I want to add 'Tel.' first. However I do not want to diplay this
title if the datafield is empty. Here is what I have done so far.

<ItemTemplate>
<asp:Label ID="BusinessLabel" runat="server" Text='<%# "Tel. "+Eval("Business") %>' CssClass="TeleStyle" />

Or This:Tel.
<asp:Label ID="BusinessLabel" runat="server" Text='<%# Eval("Business") %>' CssClass="TeleStyle" />
</ItemTemplate>

Business is a phone number. If the data field contains a number I get: Tel. 1234 123456. If the field is empty I get Tel. If Business is null I want nothing dsplayed, how do I do this?
