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?

View 1 RepliesI have a gridview with two bound fields. On clicking a button i want to display the values in first row of gridview in two textboxes. But if gridview cell is empty i am getting the text in textbox to which the value of cell is given as -' 'i know my problem will be solved if i use the template fields instead.

View 2 RepliesThe datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

I have two imagebuttons which are associated with a modalpopupextender. When I click imagebutton1, it opens up the panel and within that panel there is a grid which loads with the information. However, when I click Imagebutton2 it opens up the panel but does not display the gridview even though that gridview tag is under that panel.
find the code below:
<asp:Panel ID="PNL" ScrollBars="Auto" runat="server" Style="border: 2px solid Black; display: none; width: auto;
background-color: White; padding: 20px; text-align: center;" Height="444">
<asp:Label ID="LabelCount" runat="server" Text="Label" Font-Size="Large"
style="text-align: center"></asp:Label>
<asp:Button ID="ButtonOK" Text="OK" runat="server" />

<ItemTemplate>
test</ItemTemplate>
</asp:DataList>

Question for Print functionality in ASP.Net GridView control artical. I tried you code in my project, when click print current page, nothing happens.
So I download your code into my test web project "WebSite1", greate, it works.
Then in your CS.aspx page,
I added (which is the case of my project of using AJAX).
<asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate>
<div> <asp:GridView ID="GridView1" runat="server"

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
