The Hidden Field still carries the Old Value on the First postback - ASP.NET Discussion Boards

As you have an example you like (CodeProject), did you look at its source? you can see the main page's HTML using "View Source" in any browser, and then explicitly fetch the files it relies upon, such as the CSS and JS files

Have a look at http://s.codeproject.com/App_Themes/Std/CSS/CodeProject.min.css?dt=2.3.101117.3[^], it probably holds what you want.

Hy,
I have two application which are running simultaneously (p1,p2). If i am working on application p1, i have to restart the clock of application p2 also.For this i have written a java script code which works perfectly on my machine but gives error in server.
Here is my code

string strOut = @"
<SCRIPT language='JavaScript'>
var tparent;
alert('In PC.SearchResult.ascx Script');
debugger;
try{
if(parent.EnableClock == null)
{
alert(' In PC.SearchResult.ascx Script:parent.enableclock=null');
alert(parent.parent.EnableClock);
if(parent.parent.EnableClock == null)
{
alert('In PC.SearchResult.ascx Script: parent.parent.enableclock=null');
tparent = parent.parent.parent;
}
else
{
alert('In PC.SearchResult.ascx Script: parent.parent.enableclock!=null');
tparent = parent.parent;
}
}
else
{
alert('In PC.SearchResult.ascx Script: parent.enableclock!=null');
tparent = parent;
}
alert('The value of tparent is');
alert(tparent.value);
tparent.resetClock();
tparent.EnableClock = true;
alert(" + Session.Timeout.ToString() + ");" +
"tparent.startClock(" + Session.Timeout.ToString() + " );} catch (err){alert(err.message)}</SCRIPT>";
// string strOut = @"<SCRIPT language='JavaScript'>try{var tparent;if(parent.EnableClock == null){if(parent.parent.EnableClock == null){tparent = parent.parent.parent;}else{tparent = parent.parent;}}else{tparent = parent;} tparent.resetClock();tparent.EnableClock = true;tparent.startClock(" + Session.Timeout.ToString() + ");}catch(err){alert(err.message);}</SCRIPT>";
Response.Write(strOut);

The error that i get is when the debugger goes on "parent.parent",it says "ACCESS IS DENIED"

Please help

I open a web page with window.showModalDialog() and it works great
But when I type text in text box , TextChanged action has- then the window opened on a regular web page How can I prevent this?

Try to get the focus, to the new window.

First Page:

<html>
<head>
<title>Page 1</title>
<script language="JavaScript">
function func() {
newwin=window.showModalDialog("ModalPage.html", "popup",
"dialogLeft:50px;dialogTop:50px;dialogWidth:300px; dialogHeight:200px;center:
0");
}
</script>
</head>
<body>
<form>
<input type="button" value="Open" onClick="javascript:func()">
</form>
</body>
</html>

ModalPage:

<html>
<head>
<title>Modal Page</title>
<script language="JavaScript">
function setVar() {
document.forms[0].Name.focus();
}
</script>
</head>
<body onload="javascript:setVar()">
<form>
<input type="text" name="Name" value="Hello !!">
</form>
</body>
</html>

suppose i am showing images through datalist control. datalist have 5 rows and 5 columns. all rows and all columns will show a small image. so when i am showing images then it is taking little time. so i want to show a image pre-loader for each image. so at the very beginning when page will be running then many busy indicator will show for each image and when each image will show in the page gradually then image preloader for that image will be invisible. so please guide me how to develop my image gallery in this way.

example site is http://davidwalsh.name/dw-content/lazyload-fade.php

i want the output like above url.

thanks

You will need to use some Ajax. Post a progress image in place of the image and call an Ajax method to download the image asynchroniously, then update the image when complete. There are many, many resources and examples of this methodology.

Good Day Everyone

i have a javascript function written like this

function TestForDuplicates() {

      //Make an Arrary Values of the Textboxes
      var Texboxes = new Array(); // regular array (add an optional integer
      Texboxes[0] = document.getElementById("<%= txtUnitLen1.ClientID %>").value;      // argument to control array's size)
      Texboxes[1] = document.getElementById("<%= txtUnitLen2.ClientID %>").value;
      Texboxes[2] = document.getElementById("<%= txtUnitLen3.ClientID %>").value;
      Texboxes[3] = document.getElementById("<%= txtUnitLen4.ClientID %>").value;
      Texboxes[4] = document.getElementById("<%= txtUnitLen5.ClientID %>").value;
      Texboxes[5] = document.getElementById("<%= txtUnitLen6.ClientID %>").value;
      Texboxes[6] = document.getElementById("<%= txtUnitLen7.ClientID %>").value;
      Texboxes[7] = document.getElementById("<%= txtUnitLen8.ClientID %>").value;
      Texboxes[8] = document.getElementById("<%= txtUnitLen9.ClientID %>").value;
      Texboxes[9] = document.getElementById("<%= txtUnitLen10.ClientID %>").value;
      Texboxes[10] = document.getElementById("<%= txtUnitLen11.ClientID %>").value;
      Texboxes[11] = document.getElementById("<%= txtUnitLen12.ClientID %>").value;
      Texboxes[12] = document.getElementById("<%= txtUnitLen13.ClientID %>").value;
      Texboxes[13] = document.getElementById("<%= txtUnitLen14.ClientID %>").value;
      Texboxes[14] = document.getElementById("<%= txtUnitLen15.ClientID %>").value;
      Texboxes[15] = document.getElementById("<%= txtUnitLen16.ClientID %>").value;
      Texboxes[16] = document.getElementById("<%= txtUnitLen17.ClientID %>").value;
      Texboxes[17] = document.getElementById("<%= txtUnitLen18.ClientID %>").value;
      Texboxes[18] = document.getElementById("<%= txtUnitLen19.ClientID %>").value;
      Texboxes[19] = document.getElementById("<%= txtUnitLen20.ClientID %>").value;


      //+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
      var btn = document.getElementById("<%= btnComplete.ClientID %>");
      document.getElementById("<%= hidDuplicate.ClientID %>").value = findDuplicates(Texboxes);
      return false;
  }

and i am using the Function on the server side like this

protected void btnComplete_Click1(object sender, EventArgs e)
{


    Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "TestForDuplicates();", true);

    if (hidDuplicate.Value == null || hidDuplicate.Value == "")
    {

        Response.Write("<script>alert('There are no Duplicaets');</script>");
    }
    else
    {
        Response.Write("<script>alert('There are Duplicate Units: " + hidDuplicate.Value + "');</script>");

    }
}

and the button is defined like this

<asp:Button ID="btnComplete" runat="server" 
                     Text="Complete" Width="83px" 
                      TabIndex="20" onclick="btnComplete_Click1" />

and the hidden field like this

<asp:HiddenField ID="hidDuplicate" runat="server" />

Now this is working fine but , lets say i have 10 textboxes, if i change the value one the first textbox to be the same as the second textbox , it means it is a duplicate, now the problem here is that the value of the hidden field does not get updated immidiately , you have to click twice to get the real value.

Thanks

If the purpose is to check for duplicate values before posting the page back to the server then why are you not performing the check on the clientside before the submit?

I know the language. I've read a book. - _Madmatt

Your problem has to do with the setting of the hidden field. So you posted all of the code except for the function that sets the hidden field. You also should have something in the onclientclick of your button that will set the value on the hidden field before the submit happens.

Good Morning Gray

in the code i posted , there i part that assigns the hidden field with a value

document.getElementById("<%= hidDuplicate.ClientID %>").value = findDuplicates(Texboxes);

and the same javascript function gets called on the server side like this

Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "TestForDuplicates();", true);

Thanks

I have a content place holder in which there is a print button which creates a notepad file on the click of it for the records which are selected (checkboxes) in the grid view. The print button is placed in a

tag and the tag is hidden by default on the load of content place holder.

A javascript code is called on the onclick event of the checkbox in the grid which makes the

for print button visible (if any of the checkbox is checked) and hide it when all the checkboxes are unchecked.

The problem I am facing is that when I click on the print button then some events occurs and the content place holder refreshes and hence the

tag for the print button gets hidden although the checkboxes already checked remains checked only.

Now what i have done is: I have made the

tag visible true always and looking to write a javascript code for making the

tag invisible while the grid is not filled. But I am wondering that where should i call this particular javasscript code?

If someone could help me out?

Thanks

Varun Sareen

You would obviously want to call the javascript on the checkbox click events. You of course need logic to validate each checkbox's status and show/hide the button appropriately. I would recommand looking at JQuery[^]

Experts,

I have a excel sheet which has 7 lakhs records in which password has been encrypted. I have to decrypt the password column and find the passord whose length is greater than 7.

I have created encrypt and decrypt methods and the way to find the length of the password

----
----
----
OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$] where len(password) < 7", oledbConn);
----
----
----
My requirement is, is there any way to decrypt the whole passoword column or i have to loop through all the cells one by one.

One by one. Each piece of data is encrypted separately so it needs to be decrypted separately. If you have a piece of data that when encrypted turns into 12345 and another piece of data that turns into 67890 trying to decrypt 1234567890 would not give you the two original pieces of data (unless you are using a really horrible encryption method like ROT13). It's like if you took a zip file and chopped it in half, you aren't going to be able to unzip either piece by itself.

Hi,

I have a TabContainer that contains 5 TabPanels,
and all of them are visible = false.

At runtime i want to show only part of them,
my problem if i'm not setting the first tab to visible i can't show any other tabs.

I mean, i the fist tab prop. visible is set to false,
all other will not show even if their prop. is set to true.

is it posible???

Sounds like an odd UI design. The first tab should be the most important / most commonly used tab. If you are making it disappear then maybe you need to rethink your tab order.

Hy,
I have a web site which has two different web projects in it.the problem is when ever i am not using any page of one of the Project(P1) and using a page of the other project(p2), it give me session time out soon as session of P1 gets expired.
I have to write the code in such a way that,the session values of 2 different project can interact with each other so that even if i am not working on any of the pages to which a particular project belong ,it wont give me session time out.
