What you set the button enable value on on page load ?
After post back he don't what you set the button enable value. so you need to check on page load.
because HTTP is a state less.

Thanks for your reply!
In page load, i have set the button .Enabled = True
but whatever i type, e.g. msgbox ("Hello")
also no response...
|

|

I'm not sure you can have anything after the Response.Flush(). I think you might have further problems as it is going to treat this page like a .txt file, not an aspx page.

Thanks for your reply!
Response.Flush() <-- it will show the save as dialog and let user to save the file
it works correctly, but the button cannot change to enable = true

iam having a text box if user enters a date it should be checked if the date is in dd/mm/yyyy formate other wise it should promt the user the enter date is wron
|
|
|
|
|
better you can use some calender controls instead of allowing users to enter date.

How to remove a node in an xml file.If the xml file is like
<?xml version="1.0" encoding="ISO-8859-1"?>
<countries>
<country>
<text>India</text>
<value>I</value>
</country>
<country>
<value>A</value>
</country>
<country>
<value>F</value>
</country>
</countries>
I want to remove the node country.How is it possible..
|

As per my perception, this is possible with Dataset.
Load the XML into Dataaset and manipulate it whatever you want. This is the easy way.

hi all
am using asp.net 2.0 with ajax...if am trying to debug any page by putting a break point and in between if i stopped for a while den the following error is coming....den after tht again i nne d to close and run it again
Error:
sys.WebForms.PageRequestManagerTimeoutException:The server request timed out.
?
|
|
|
|
|
Try setting AsyncPostBackTimeOut property of scriptmanager to a large time. Do you have a long running process ? I guess it is waiting for completion and getting timeout.
|
|
|
|
|
i think u r using ScriptManager. then it is not error. u r taking lots of time to debug ur program then its fire. u increase ur AsyncPostBackTimeout time in property of ScriptManager.

hi all...
i have put a div tag inside table......
the code is like this
<td style="width: 14%;height:100%" >
<table style="height:100%;width:100%;">
<tr>
<td valign="top" style="background-color:#C7B39A;height:525px;width:214px;" >
<div style="POSITION: absolute; HEIGHT: 530px;width:100%; z-index: 100;background-color:#E6DDD2; left: 0px; top: 0px;overflow:auto">
<uc2:uc_NavigationTree_Reports ID="Uc_NavigationTree_Reports1" runat="server" />
</div>
</td>
</tr>
</table>
</td>
here first TD width is 14%...the table inside the TD is 100%..so it wl take the 100% of that 14%....correct?...so in the div also i have given 100%....so it should take the 100% of tha table....
this was working fine before,that time i was using IE6...now i am using IE7....now the div is taking the full spacelike it is coiming full scraan....why is it happening like that?

Hi Sandhya,
Is it neccesary to take the "z-index " in the div? Try to remove it from div and try again. I am not sure for this, but you can try it.
Regards,
Keep Smiling
