Is it possible to validate a date format when you use a form view to enter the record into the database? I have a form view that is used to sign out for the day or week. I need to dates to be in mm/dd/yyyy format. Is there someway to use the validation controls so that it won't let you enter the record unless it is correct and will prompt them to enter the right info.

I have the following piece of code which I was hoping would result in an error message being displayed if an incorrect date format was input rather than an website error page saying "The string was not recognized as a valid DateTime."
<asp:TemplateField HeaderText="DateCompleted" SortExpression="DateCompleted"> <EditItemTemplate> <asp:TextBox ID="TextBox2" runat="server" Text='<%# Bind("DateCompleted") %>'> </asp:TextBox> <asp:CompareValidator ID="CompareValidator" ValidationGroup="GridView1" ControlToValidate="TextBox2" errormessage="Invalid Date" Display="Dynamic" Operator="DataTypeCheck" Type="Date" runat="Server" /> </EditItemTemplate> <ItemTemplate> <asp:Label ID="Label2" runat="server" Text='<%# Bind("DateCompleted") %>'></asp:Label> </ItemTemplate> </asp:TemplateField>
I'm looking for the best way (Performance) to do gridview columns formating RunTime /Dynamic depending on the datatable Columns type ,I want to bind the datatable to a gridview and format the Date columns to short date, and currency columns formatted with comma ex 10,000.00 inplace 100000.00 at datatable the column type is double run time (without converting them to String) since I do a filtering and sorting at these columns.

I have written a small web app to take fill a dataset from an xml file, which is then bound to a Gridview control. The problem I am having is that I am trying to format a date field as it is currently displayed as '2010-06-03T16:37:26.043+01:00'. I can usually set a format to an item within a templatefield by setting the bind or eval text, but in this case I cannot.

I want for the date to be displayed in the Grid at the following format MM/YYYY - that is:
Databound
Databound
Till Period
From Period
Databound
(I have just started programming in C#.net via Microsoft Visual Studio 2010, so I really don't have programming knowledge yet).
From the database - 2 of my GridView cells: From Period, and Till Period - retrieve dates in the format YYYYMM - that is: just Year and Month. For Example:
Databound
Databound
Till Period
From Period
Databound
200008
200005
200011
200009

I am having a table with some fields in which one field is emp's DOB of varchar datatype.I want to display the date in Gridview in 'DD-MM-YYYY' format as well as the dates should be in sorted in descending order.
For e.g:12/03/2010' should be displayed before '12/03/2009'.
I have 2 textboxes in my page. One is supposed to hold the Date and the other Time. These 2 data are merged when saving into one database field having a datetime datatype. Upon retrieve, the datetime field value is split into 2 and put into the Date Textbox and Time TextBox.
Upon input, when I am trying to update, the validator always says "Invalid Time."

I want to pass date from one page to another page using querystring. I have used a gridview hyperlinkfield.
When user click hyperlink in gridview the data should display on other page.
I have tried this but due to date format (dd/MM/yyyy) that is showing in gridview the hyperlink is not showing. I think '/' is creating problem. In gridview I already tried by replacing / to -.
I want to have a date format in gridview column when user is in edit mode.
That is when user is editing the date he should automatically get the format like this
'--/--/----' (i.e 12/01/2010) now he can write his desired date, he is not going to type the forward slash "/" using Key Board.
