trapping a click on calendar control

On the standard asp.net calendar control how can I pick up the fact that the selected date has been clicked? I have created a user control that displays the calendar control within a panel when a button is clicked. When the selection is changed the panel is hidden. Works ace except that if the currently selected date is clicked I also want to disappear the panel. Clicking on the selected date doesn’t disappear the thing, and I can’t find another event to trap the click on the calendar. Can anyone help? Its driving me crazy. The user can close the calendar by clicking the button again, but I know my users and there will be much complaining about it not disappearing when they select the same day, and I would kinda agree with them too!  thanks in advance

Cheers

ASP .NET Custom Controls

Hi,

As part of a project, I need to create a custom ASP .NET control that outputs a few lines of HTML including Javascript on to the page. I searched the internet and followed a few tutorials such as this one:

http://blogs.msdn.com/coding4fun/archive/2007/05/05/2429765.aspx

I tried following the instructions and the code compiles OK, but when it loads in the browser I get an error. It states that the tag is an unknown server tag. This is despite the fact that the class's code file is in the App_Code folder and the namespace matches the one in the web.config file.

I also tried other tutorials that involved putting the control in a class library. I couldn't get that to work either. If I try to add a reference to the DLL, it does it on the local machine and not the server.

I'm using Visual Web Developer, although I also bought Visual Studio 2005 Standard recently. I am connecting to a remote web server using FTP.

Does anybody have any suggestions? Any help would really be appreciated.

Thanks,

James

Are you registering the custom tag on the top of ASPX page ?

Hi,

Yes, I have tried using the following within the relevant page:

<br />
<%@ Register TagPrefix="cust" Namespace="myControls" %><br />

I also tried modifying the Web.config file like so:

<br />
<pages><br />
<br />
  <controls><br />
<br />
    <add tagPrefix="cust" namespace="myControls"/><br />
<br />
  </controls><br />
<br />
</pages><br />

myControls matches the namespace containing the control. The author of the article suggests that doing either of these should be enough. Intellisense correctly recognises the tag and the pages compile OK. But I get the error I mentioned in the first post. I suspect that the code compiled for the control is not being sent to the server for some reason.

Hi,

Thank you for the replies. I am having trouble understanding the difference between a user control and a custom control. The article I mentioned is about custom controls, inheriting from the WebControl class. The user control is a different thing, and I'm not sure if it can do what I need. The control will need to output Javascript, but dynamically setting the contents of a script tag is difficult because ASP .NET seems to try to interpret the code as C# code, even with the type set to "text/javascript".

@Navaneeth:

It seems I can't use the src attribute because it doesn't seem to work for custom web controls, only user controls.

@Sandeep:

The control is in a CS file in the App_Code directory, so it's not within an assembly. According to the article this should be OK.

trapping errors in asynchronous page

In my application, i need to generate a pdf which takes around 10 minutes. The pdf generation code i have written in a page which i have made as an asynchronous page. for this i have added a httphandler in the web.config file too. I have a global error catch httpmodule in my app. It traps the errors throughout the application. But the problem is the error module doesn't trap any error generated by asynchronous page. Is there anyway I can trap the errors generated by asynchronous page? I am badly need of this

Thanks in advance

I have a page viz. printform.aspx. This doesn't have any controls. It just has the code for generating the pdf. In the web.config file, i have added an httphandler for this page. So when I tried to load this page, it execute as an asynchronous page and the pdf generation will be a back ground process. This is the implementation.

Hi All,

I need to enter decimal value in a textbox but only one decimal.
For eg: 55.3 (Valid)

It should not accept second decimal.
Also, I need to validate for dash(-) ie it should not accept minus sign.

I want to use javascript for this.

Please help...

Thanks in advance...

Hi Varsha
Have look at this code i think you are looking for the same

<br />
 function CheckText()<br />
    {<br />
        var returnValue=false;<br />
        var text=document.getElementById("TextBox1").value;<br />
        var temp=new Array();<br />
        var temp1=new Array();<br />
        <br />
        //Code for checking minus<br />
         for(var index=0;index<text.length;index++)<br />
      {<br />
           <br />
            if(text.charAt(index)=='-')<br />
            {<br />
                alert("Text Containd Minus");<br />
                returnValue=false;<br />
                break;<br />
            }<br />
      <br />
      }<br />
        // logic to get digits after decimal <br />
        temp = text.split('.');<br />
        <br />
         if(temp!='undefined' && temp.length>2)<br />
        {<br />
            alert("Text Contains more than 1 decimal ");<br />
            returnValue=false;<br />
        }<br />
        <br />
     <br />
       return returnValue;<br />
      <br />
    }<br />

You can check the dot in the loop itself but the complexity will increase

For this u have to create 3 validators. Apply 2 validators for save button and 1 validator for cancel button.
Check the Validation Group property in Save button and its validators, Apply the same name for both.
Apply the different Validation Group name for cancel button.
