Question

I’m trying to insert date with “MM/dd/yyyy” Format into a date format field in a detailed view. But I am gettin error Message:

 String was not recognized as a valid DateTime

I tried Like

<asp:TextBox ID="TextBox2" runat="server" 
Text='<%# Bind("RenewalDate","{0,MM/dd/yyyy}")%>' ></asp:TextBox>

How can I insert date with format MM/dd/yyyy????

Answer 1

The format string is invalid. You need a colon after the placeholder instead of a comma:

Text='<%# Bind("RenewalDate","{0:MM/dd/yyyy}")%>'

That should fix the problem, assuming RenewalDate is a DateTime column. If it isn’t a DateTime column, you’ll need to convert it before you apply the format:

Text='<%# Convert.ToDateTime(Bind("RenewalDate")).ToString("MM/dd/yyyy") %>'

EDIT

To ensure that the input is valid, you can add compare and required field validators:

<asp:RequiredFieldValidator ID="reqDateValidator" runat="server" Display="Dynamic" ErrorMessage="*" ControlToValidate="TextBox1" />
<asp:CompareValidator
    id="dateValidator" runat="server" 
    Type="Date"
    Operator="DataTypeCheck"
    ControlToValidate="TextBox1" 
    ErrorMessage="Invalid Date">
</asp:CompareValidator>
