I have a DetailsView on the page and I have made one of the fields a TemplateField. In the EditItemTemplate and InsertItemTemplate I have a DropdownList that is databound to a table in my Sql Server database. I wanted to add an initial value to the DropdownList
namely "- select -" .
I set the AppendDataBoundItems property to true and added the initial value as a ListItem.Markup of the DropdownList
<asp:DropDownList ID="DropDownList_HP" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_HP" [code]...
This works fine for new input. The problem is however that the database already has records that were entered through a Windows Application and many of these records has a null value in this field and exceptions are thrown when I tried to open these records
and the system tried to set the SelectedValue of the DropdownList.After some more searching I found this help
http://msdn.microsoft.com/en-us/library/ms366709.aspx
So I changed the ListItem in the DropDownList markup to the following:
<asp:DropDownList ID="DropDownList_RefHospDV4" runat="server"
AppendDataBoundItems="True" DataSourceID="SqlDataSource_RefHosp" [code]...
This now solved the problem of opening a record where the value is null in the database, BUT now the RequiredFieldValidator is not validating anymore to make sure that a databound item is selected for this field and not the initial value "- select -". So basically now it is not checking anymore to see if valid input has been entered for the DropDownList and it accepts "- select -" thus it acts as if the field is not a required field anymore.
In short what is required is that I want to make sure that the user enters a valid selection in the DropDownList, but it must also cater for old records that do not have this field entered yet so that those old records can be opened in the DetailsView .Opening Old records (with null in that field):When these old records are opened in the DetailsView the DropDownlist should show "- select -" when the value in the database is null.
Saving records (old or new records):When saving the record in Insert mode or Update mode the RequiredFieldValidator should show that a valid input is not selected if the DropDownList is still on "- select -".

i have imported data from excel to datatable but i need to validate port no column which should
allow only numeric value and also i need to check the single quotes and need to replace to double quotes.
If i use DataAnnotations on my Model and my model have something like this:
[Code]....
and in my View, i have a textbox WITHOUT client side validation. If the user enter non-numbers caracters in this field, i would like to validate on the server side that the user have entered non-authorized caracters and message him back on that. But since that my Model's Days property is a INT, the ModelBinder can't parse the string in the int property and generate an error in the ModelState with no message at all. And if the user doesnt enter anything on this field, the ModelBinder also try to put an empty string in a int property and generate an error in the ModelState with the message "a value is required". This is not the message that is written within the DataAnnotation. I have no control on the message that is generated.
So my question is:how can i valide the users input for int properties (or DateTime, etc...) and if the user enter a bad value i can put in the ValidationSummary something like this: "You can't only enter a numeric value for Days".
I have the code below that works fine, but I need to have more than one field using the same command.

{
string val = e.OldValues["txtDate2"].ToString();
}

I have <asp:Button ID="btnDelete" ..../> and <asp:DataList ID="lstOrder"..../>
"lstOrder" has <asp:CheckBox ..../> for each "lstOrder" item. I am binding "lstOrder" to DataTable at run time (DataTable is being created dynamically"
"btnDelete" first loops through the "lstOrder" and stores the indexes of items which are marked(checked). Next rows are deleted from the DataTable and "lstOrder" is binded again.
I don't want to postback if none of the items are marked in the "lstOrder"
How to validate ?
