View 5 RepliesValidation - Rangevalidator For Calendar Extender Entries In Safari?
Mar 24, 2010I have the following scenario:
arrival and departure dates have to be selected on a form, through 2 textboxes with a calendar extender each.
I validate the entries to check that no date before today is selected and to check that the departure is after the arrival. I used a rangevalidator and a comparevalidator.
In IE, Firefox and Opera it is working fine, in Safari (on windows) however both the validators go off even on entries that should be accepted.
It makes me suspect that the date format dd/MM/yyyy causes trouble for Safari.
(the dd/MMMM/yyyy also gave the same troubles in the other browsers, probably due to the dependency on UIculture)
The code is:
<tr>
<td>
<asp:TextBox ID="txtArrive" runat="server"></asp:TextBox>
<cc1:TextBoxWatermarkExtender ID="txtArriveWatermarkExt" runat="server"
Enabled="True" TargetControlID="txtArrive" WatermarkText="arrival date">

Forms Data Controls :: Refresh A Gridview When Textchanged Event Occurs?

Within it, I have a repeater, inside of ITEMTEMPLATE I put one TextBox for product quantities and one Button, for update the quantity inserted on that textbox.

Web Forms :: RegularExpressionValidation (moving From RangeValidator)?
Dec 9, 2010I am using RangeValidator whose Minimum and Maximum vales are set in code behind dynamically. Minimum and Maximum values are exracted form the database. These values are in the range of 0 to n (integers only). Therefore user can enter values from0 to n (integers only).Now I have a situation where user can also put -1 which can't be handled by range validator. So my last option is to regular expression to handle such situation.Valid values for the user are (-1, 0-n). But I don't now how to get such regular expression , any help would be appreciated. I can manipulate expression in code behind based on values extracted from the database.Also , maximum possible value for n is 255 (Note: minimum and maximum values are extracted from the database)
