View 3 RepliesI 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?

View 5 RepliesI am using c# with VS 2010 and dynamic data. I have a gridview that is populated by scaffolding. I then want to use the "Delete" command on the row. While the command works fine, it does not seem to know the datarecord has child tables in a one to many relationship, thus it wont properly delete the child tables before deleting the parent table. Which is fine, i can call some linq to sql to get the table id and delete all of its children before the parent table is deleted. Odd thing is, the Gridview is retruning "" emtpry strings for the cell that has the table uniqe ID.

I am working with a gridview that pulls data from a SQL database based on selections in dropdown lists. The source table has six columns for attributes of the selection, but depending on what is chosen, there could be anywhere from one to six of those that are empty (all null values). When the column is empty, I would like to have it hidden so the page is less clunky and confusing.
I've searched around for an answer for the past couple days, but what I have found so far is either related to hiding columns that you know are empty which I will not know or removing them in the SQL code which I think doesn't work if the column is called for in the gridview code and doesn't exist in the query.

I am building a Web Content form in which the user enters some data in asp:TextBoxes, and presses submit to store the data in the database.

Note that I have implemented code, which sets my TextBox.Text = string.Empty in my aspx.cs file, which of course does not work since I am using the update panel with an AsyncPostBackTrigger...

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
