Easy DateTime question

I have never used a check constraint in the way you are wanting to use it. I am not sure it can be done. If all records getting inserted had a certain rule then a check constraint would be the correct one to use. I am under the impression that each record might have a different rule. In that case I would not use the check constraint. Ben

It is going to be a complicated solution. I think you should just try your best and figure it out any way you can. Ben

The rowfilter you can use in a DataView. I can't remeber if you do vb.net or C# but it is something like this: DataView dv = yourdatatable.DefaultView; dv.RowFilter = "columname = "+textbox.Text; gridview.datasource = dv; gridview.databind(); Anyway, that is what the C# looks like. Ben

Here is the content of the link: Subtracts the specified date and time from this instance. Namespace: System Assembly: mscorlib (in mscorlib.dll) Syntax Visual Basic (Declaration) Public Function Subtract ( _ value As DateTime _ ) As TimeSpan Visual Basic (Usage) Dim instance As DateTime Dim value As DateTime Dim returnValue As TimeSpan returnValue = instance.Subtract(value) C# public TimeSpan Subtract ( DateTime value ) C++ public: TimeSpan Subtract ( DateTime value ) J# public TimeSpan Subtract ( DateTime value ) JScript public function Subtract ( value : DateTime ) : TimeSpan Parameters value An instance of DateTime. Return Value A TimeSpan interval equal to the date and time represented by this instance minus the date and time represented by value. Exceptions Exception type Condition ArgumentOutOfRangeException The result is less than MinValue or greater than MaxValue. Remarks This method does not change the value of this DateTime object. Instead, a new TimeSpan is returned whose value is the result of this operation. Before subtracting DateTime objects, insure that the objects represent times in the same time zone. Otherwise, the result will include the difference between time zones. Example The following code example demonstrates the Subtract method and operator. Visual Basic Copy Code Dim date1 As New System.DateTime(1996, 6, 3, 22, 15, 0) Dim date2 As New System.DateTime(1996, 12, 6, 13, 2, 0) Dim date3 As New System.DateTime(1996, 10, 12, 8, 42, 0) Dim diff1 As System.TimeSpan ' diff1 gets 185 days, 14 hours, and 47 minutes. diff1 = date2.Subtract(date1) Dim date4 As System.DateTime ' date4 gets 4/9/1996 5:55:00 PM. date4 = date3.Subtract(diff1) Dim diff2 As System.TimeSpan ' diff2 gets 55 days 4 hours and 20 minutes. diff2 = System.DateTime.op_Subtraction(date2, date3) Dim date5 As System.DateTime ' date5 gets 4/9/1996 5:55:00 PM. date5 = System.DateTime.op_Subtraction(date1, diff2) Ben

What are the settings to be change for me to show the header on load?. I found out that it depends on the number of rows. Thanks bernie

In the gridview prerender event you need this kind of code: if (!GridView1.TopPagerRow.Visible) { GridView1.TopPagerRow.Visible = true; } Ben
this is a C# code right?how about in VB?. i tried to write as if GridView1.TopPagerRow.Visible = false then GridView1.TopPagerRow.Visible = true but i got some error "Object reference not set to an instance of an object." is that because my gridview was controlled by dropdown?.How can i do that? Bernie

You need to turn paging on. Set the page size to be really big so you only have one page. Ben
is that the only setting that i need? it will not display the next or previous? Bernie
