Working in asp.net 2.0/C#
I have a form in my webpage.aspx file that implements a droplist control. The form looks like this:
<form id="formEmpSurvey" runat="server">
<center>
<br />
<table style="width:680px;" border="0" cellspacing="0" cellpadding="0">
<tr>
<td style="width: 187px; height: 26px;" align="left">
<asp:CheckBox ID="checkSymptomCough" runat="server" Text="Persistent cough" Enabled="True" />
</td>
<td style="width: 250px; height: 26px;" align="right">
<asp:Label ID="labelDurationCough" runat="server" Text="Duration" Enabled="False"></asp:Label>
<asp:DropDownList ID="comboDurationCough" runat="server" Enabled="False">
<asp:ListItem Value="0">Choose One...</asp:ListItem>
<asp:ListItem Value="1">Less than one month</asp:ListItem>
<asp:ListItem Value="2">1 month</asp:ListItem>
<asp:ListItem Value="3">2 months</asp:ListItem>
<asp:ListItem Value="4">3 months</asp:ListItem>
<asp:ListItem Value="5">4 months</asp:ListItem>
<asp:ListItem Value="6">5 months</asp:ListItem>
<asp:ListItem Value="7">6 months</asp:ListItem>
<asp:ListItem Value="8">More than 6 months</asp:ListItem>
</asp:DropDownList>
</td>
</tr>
</table>
</form>
Next, I have javascript that looks like this:
//------------------------------------------------------------------------------
function disableLabel(lbl, disable)
{
lbl.obj.disabled = disable;
}
//------------------------------------------------------------------------------
function disableCombo(combo, disable)
{
combo.obj.disabled = disable;
}
//------------------------------------------------------------------------------
function resetCombo(combo)
{
combo.selectedIndex = 0;
}
//------------------------------------------------------------------------------
function checkChanged(name)
{
var check = new getObj("checkSymptom" + name);
var label = new getObj("labelDuration" + name);
var combo = new getObj("comboDuration" + name);
// if the checkbox is checked, enable the duration lable/combobox pair
if (check.obj.checked == true)
{
disableLabel(label, false);
disableCombo(combo, false);
}
else
{
// otherwise, reset the combo selection and disable them
resetCombo(combo);
disableLabel(label, true);
disableCombo(combo, true);
}
}
//------------------------------------------------------------------------------
function checkCoughChanged()
{
checkChanged("Cough");
}
Finally, in the aspx.cs Page_Load function, I have this:
protected void Page_Load(object sender, EventArgs e)
{
checkSymptomCough.Attributes.Add("onclick", "checkCoughChanged();");
}
====================================
As you can see, the label and droplist start out in a disabled state. When I check the checkbox, the form correctly enables the label and the droplist controls.
When I un-check the checkbox, the desired result is that the label and droplist become disabled, and the droplist set to the 0'th index ("Select One...").
However, when I un-check the checkbox, the label and droplist are correctly disabled, but the selection in the droplist doesn't change.
IE reports no javascript errors at all.
What am I doing wrong?

I think that your problem is in resetCombo / combo.SelectedIndex = 0. 0 is a valid index (at least in c#). You might try comob.SelectedIndex = -1, or combo.SelectedItem = null.

Neither of those worked (separately or combined).

I changed the resetCombo() function as follows:
function resetCombo(name)
{
if (name == "Cough")
{
document.formEmpSurvey.comboDurationCough.selectedIndex=0;
}
else if (name=="blah blah")
{
}
}

Apparently my brain was a little sleepy last night, and the code I gave was in c#, not in javascript. Glad you got it figured out.

I have 2 Web Pages page1.aspx and page2.aspx.
On page1.aspx i am selecting values fom list box and transfering to page2.aspx using Button -- "Select".This works fine.
Suppose user doesn't select any value from list box then message box pops up to user ...code for messagebox is like this
Private Sub btnHighlightYears_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnHighlightYears.Click
If Lstbox_Years.SelectedValue.ToString() = "" Then
MessageBox.Show("Please Select Atleast One Year")
Else
Server.Transfer("Acct_Details.aspx?type=h")
End If
End Sub
Message box is a class and using java script and other controls it is made - which looks similar like a windows based application message box.
Now on page1.aspx i have one more button - "Select All and Continue".This also works fine and transfers me to page2.aspx
Problem
=======
When i first click on Button -- "Select" and nothing is selected fom list box then message box pops up ...click okay and then click button - "Select All and Continue" and it takes me to pafe2.aspx.
When i returns back to page1.aspx through Back button if IE/browser , the message box again pops up.
Is it an error or an issue...How can i solve this ?
Please help me.
Thanks,
|

It pops up again because it is displaying the cached page that is in your history. I imagine the back button is similar to javascript:history.go(-1);
I don't know if restricting the caching of the page will work or not, but i have a domain hosting control panel that always (seems to) re-request a page when i click the back button on the browser. This would be the result you are aiming for, then you can check server side if you want the message box code to be written into the page.

Using Javascript to run the window.open method
IE 7 always puts a url bar just under the Titlebar. IE6 does not do this. Does anyone know how to get rid of it? None of the IE BOM settings work:
open("myfile.html","_blank","directories=no, height=400, left=100, location=no, menubar=no, resizable=yes, scrollbars=no, status=yes, titlebar=no, toolbar=no, top=100, width=400)
This is totally annoying... can't find anything on the MS site about it either

You can't get rid of it. It's a security feature.

Thank you again... guess I'll have to design my way around it 
I did find this link finally that explains the why and wherefor:
http://blogs.msdn.com/ie/archive/2005/11/21/495507.aspx[^]
I can see why MS does it... but I wish they'd made it "more beautiful" ... the address bar just "hangs out in the middle of nothing if you don't set the toolbar / menubar. Seems like MS could have made it so that the address bar sits within the menubar but without the buttons <sigh>.

Hi All
I need to know whether isolating a website in a separate application pool on the server causes the initial page load to be slower or not??
My website is hosted on a webserver but lately they isolated it into a separate application pool but I noticed a slower load so is these cuz of the new application pool??
Thanks a lot in advance
|
|
|
|

There is no reason why one application pool would be slower than another.
I think that it's the other way around. You are experiencing the same performance problem that they try to rectify by doing changes to the server.

I am new to asp ...please help me...
Thanking you in anticipation.
If you fail for the first time , call it version 1.0.

to kill the entire session use: Session.Abandon

Hi,
I require Javascript code for the below. Please help me if anybody knows.
I have a datagrid with link buttons. The Datagrid contains Analyst Name and Site. While clicking on any Analyst Name or Site, the corresponding entry will come in two text boxes below the grid for modifying. This is the business requirement. Even though I am doing this using Item Command Event of Datagrid, it comes with a postback. Could anybody please help me by giving javascript code for this so that I can avoid this unnecessary postback? That is, while clicking on the grid, the corresponding entry should come in the text boxes. The item may be 7th , or 1st, or 16th. But there will be only one entry at a time.
Advance thanks for any help.
Regards

Hi Guys,
I would appreciate it if any body can give/show me some html/flash free templates for a simple web site for a business company.
Thanks in advance 
|
|
|
|
|
So you want free templates?? You do realize this site is for developers who create those sites...
Anyway I think you will find it hard to get a "flash and html" template simply because flash should only be used for specific tasks. You would not have a pulsating Welcome sign on a business website.
Did you have any designs in mind?
|
|
|
|
|
Hi,
Unfortunately, i don't have any thing in my mind, but the customer has something that he don't know yet. He want me to show him something simple but yet impressing. So, any thing modern will do even if with out flash embedded.
Thanks again
|
|
|
|
|
When you say modern do you mean wikipedia modern or adobe.com modern or what?
Give me some information on your customer and i'll try help you.
Use Email.
