Hi,
it's possible.

for ex: When you are pressing a button you want to validate a text box.
In Page load add following code
MyButton.Attributes.Add("onclick", "javascript:MyJSFun('" & MyTextBox.ClientID & "')")

Then your JS function.

<br />
function MyJSFun(txt)<br />
{ <br />
//This will print the textbox value(ASP text box).<br />
alert(document.getElementById(txt).value)<br />
}<br />

To succeed, we must first believe that we can.

why don't you use the required field validator control for that.

by using that, your page will not be postbacked and authencation will be done at client side

Hi Add a requiredFieldValidator from validation controls.
Set ControlToValidate,errormessege Properties of the validator control.
Control to validate will be your textbox name.

Thats all....

drag a requiredfieldvalidator control next to your username textbox control

set the controltovalidate property of your requiredfieldvalidator control
set the error message property u want to display for example "User Name Required"
set the text property of your required field property to "*"

repeat this for password field

both username and password textboxes must contain a attribute <runat='server'> in their html view

now if u want to display the error messages at one place u can also just drag drop the validationsummary control

there u go...
if still u face a problem try google Smile | :)

or ask again Smile | :)

Hi,
I created one user with name "srinivasanb" and pwd "Mpls7880" in my system giving full rights for that user( In my system only i have docs folder for file server) and same username & pwd was created on host system there also giving full rights for that user.

In put web.config and data.config and bin folder,template folder,xml folder,documents folders in docs folder in my system.

In web.config file i included the following code
------------------------------------------------

httpHandlers
add verb="*" path="*.pdf" type="Coverpoint.WillisBloodstock.BusinessServices.FileHandler,BusinessServices"
add verb="*" path="*.doc" type="Coverpoint.WillisBloodstock.BusinessServices.FileHandler,BusinessServices"
add verb="*" path="*.xml" type="Coverpoint.WillisBloodstock.BusinessServices.FileHandler,BusinessServices"
add verb="*" path="*.xls" type="Coverpoint.WillisBloodstock.BusinessServices.FileHandler,BusinessServices"
/httpHandlers

add key="WebSiteURL" value="http://localhost/Bloodstock2.2/"/

authentication mode="None"/

authorization
allow users="*"/
/authorization

In globalization tag i am giving the username and password which were created in my system and hosted machince (on both machines users should have same name and pwd)

identity impersonate="true" userName="zslindia\srinivasanb"
password="Mpls7880" /

Note:I removed less thn and greater than symbols ( tags )in web.config please recognise so that to print user friendly

login.aspx

I also had the same message. But i was not using any security related things in my Web App. I resolved my problem by running "aspnet_regiis -i". When I had this problem i searched and found that this problem arises if IIS is installed after the VS.Net 2005 / 2003. Try this. It might help you too.

Hi add a div in to your page, where you want to add the text box.
eg:

<br />
          <div id="div1"></div><br />

then in your javascripr code add following code to create text box

<br />
  document.getElementById("div1").innerHTML+="<input type='text'  <br />
  name='text1'/>";<br />

I think this will help You. please post your result.
