Tutorial :Date format in RangeValidator



Question:

I am using RangeValidator to validate date enter in textbox and its working fine with default date format but now i want the date format in "dd/MM/yyy" but its generating excption with this date format. please provide me solution my code:

in aspx page:

<asp:TextBox ID="txtrequiredby" runat="server" ></asp:TextBox >  <cc1:CalendarExtender ID="txtrequiredby_CalendarExtender" Format="dd/MM/yyyy"  runat="server" Enabled="True" TargetControlID="txtrequiredby" >  </cc1:CalendarExtender >     <asp:RangeValidator ID="rvreqby" runat="server" ErrorMessage="Required By Date  Greater Than or Equal to current date" ControlToValidate="txtrequiredby"    Display="Dynamic" Type="Date" ></asp:RangeValidator >  

in codebehind:

rvreqby.MinimumValue = clsGeneral.FromSqlDate( DateTime.Now);  rvreqby.MaximumValue = clsGeneral.FromSqlDate( DateTime.Now.AddYears(200));    public static string  FromSqlDate(DateTime  date)  {     return date.ToString("dd/MM/yyyy");  }  


Solution:1

MinimumValue & MaximumValue need to be set in the Page_PreRender event and appear to require the date format as "dd-MM-yy"...see last post on Rangevalidator Min Max Value error

protected void Page_PreRender(object sender, EventArgs e)  {      RangeValidator1.MinimumValue = DateTime.Now.Date.ToString("dd-MM-yy");      RangeValidator1.MaximumValue = DateTime.Now.Date.AddYears(90).ToString("dd-MM-yy");  }  


Solution:2

Format of the MinimumValue and MaximumValue should be yyyy/MM/dd
