Visibility problem with ajax control

hi,

I have a textbox and required field validator control.when the page is 1st loaded the Textbox is invisible and after clicking a button it becomes visible but

the problem is that the validator control is not working though the text box is visible now? why any idea pls?

Hi,

Can you post sample code to illustratete problem? I cannot get the same problem just by placing textbox and required validator in update panel and makeing TextBox invisible initially.

If you are using Validators inside UpdatePanel, then it is not compatible with it

You can download compatible validators control from here

hi,

I have used the usual asp validators.Now I have add the tag mapping required in web.config file and add reference to validation.dll.But when I run the program it shows error in my user controls which are in another folder with a custom namespace.any idea pls? the pages are not showing error but the user controls are showing error.By the By the Pages where these user controls are imported are also in a folder.

pls reply...


I have put the error messags given in my User Controls below:

pls see this and reply quickly............

Error 150 Could not load file or assembly 'Validators, Version=1.0.0.0' or one of its dependencies. The system cannot find the file specified. (D:\SSDTracker\Tracker\web.config line 92) D:\SSDTracker\Tracker\User Controls\CompetencyDatabase\CompetencySectionUI.ascx 32


Hi,

I think the error message explained the issue clear.Make sure Validators.dll is in the right folder and the version of it is right. Make sure you made the right setting in the config file.

Good luck!

Watermark Extender Validation error

I have a textbox with an ajax watermark extender attached to it. As well as a required feild validator. One button on my page is "CauseValidation = true". Before i applyed the watermark extender the validation check worked perfectly, but now the validation check doesnt work as i think it see`s the watermarktext as text in the textbox, is there any way around this? si!

Hi blink18jew,

Would you mind posting your simple source code here?


sure its like this :

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TestBox" ErrorMessage="ERROR"></asp:RequiredFieldValidator>
<asp:TextBox ID="TestBox" runat="server"></asp:TextBox>
<ajaxToolkit:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" TargetControlID="TestBox" WatermarkText="Watermarked..." WatermarkCssClass="water" runat="server">
</ajaxToolkit:TextBoxWatermarkExtender>

the watermark seems to ruin the validation checks...si!


Hi blink18jew,

I'm afraid that I cannot reproduce your problem.Here is my test sampe based on yours. It works fine locally.

Aspx:

<%@. Page Language="VB" %><!DOCTYPE html PUBLIC"-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server"></script><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>Water Mark</title></head><body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TestBox" ErrorMessage="ERROR"></asp:RequiredFieldValidator> <asp:TextBox ID="TestBox" runat="server" CausesValidation="true"></asp:TextBox> <ajaxToolkit:TextBoxWatermarkExtender ID="TextBoxWatermarkExtender1" TargetControlID="TestBox" WatermarkText="Watermarked..." WatermarkCssClass="water" runat="server"> </ajaxToolkit:TextBoxWatermarkExtender> <asp:Button ID="Button1" runat="server" Text="Button" /> </form></body></html>

So would you give us more details including source code or error information? If you can help us reproducing your problem step by step, it will be greatly appreciated.

By the way, did you use your Validator in a UpdatePanel? If yes, maybe you can benefit from this thread: http://forums.asp.net/t/1066821.aspx

Hope it helps.
