Hi all.
I have a slight problem on a project I'm working on. The way things are structured is: I have a master page (obviously with the placeholder for the children). I have the placeholder surrounded by an ajax update panel (this was the only work around for a problem we had). Now the children pages all bind their drop downs with tables from an MDB.
The problem? Some pages (even though some have like only three drop downs) take AGES to bind. And even more when a button is clicked (this shouldn't post back as it's in an update panel right?).
I don't see why this is happening in only particular pages. Sometimes, a very short page takes 10-20 seconds to respond to a click, whilst much larger pages respond instantly.
What could be the problem? I'm blocked.

If you use server code to print the bar code, it's obviously going to be printed on a printer connected to the server. You can't access the client printer from the server code.
You could render the barcode as an image to display in the browser, so that the user can print it.

I have a panel in masterpage.how can I change the visiabillity of that panel from codebehind of another page like homepage?
|
|
|
|
|
Master page's control can be accessed from all the Contentpages that have the same masterpage.Check the panel as runat="server" and get the control in codebehind and change the visibility according your needs.
Cheers!!

Hi...
You can get the refernce of Master page control like this and handle as you need
Panel pn = (Panel)Master.FindControl("Panel1");
Response.Write(pn.ID);
pn.Visible = false;
|
|
|
|
|
Cast the reference in Page.Master to the specific type of your master page class, then you can access it's controls. Example:
((MyFabulousMasterPage)Page.Master).MyGreatPanel.Visible = false;
Despite everything, the person most likely to be fooling you next is yourself.

Dear Friends,
I want to know that what process take place at page level when any Exception fired and how was it handle by default by the Exception Handler class.
Please give me any link regarding this.
Thanks and Regards,

if you have any method where you didnt handle Exception , using Try , Catch then you have to handle the Error using Following way
1. Page Level
if you handel exception in page level there is a event Page_error where you can handle.
void Page_Error(Object o,EventArgs e)
{
Trace.Write("Error Message " + Server.GetLastError());
Server.ClearError();
}
Note : You can print this Error in any conrols, because from Page_Error Event you dont have any access of any control
2. Application Level:
in Gloabl.asax , ther is and event which fires when any application level error happen.
void Application_Error(object sender, EventArgs e)
{
}
Hope this clear your doubt.
cheers,
Abhijit

hi all,
I have a grid which contains checkboxes(similar to mail inbox).I have one href control outside the grid.When i click all the chekboxes inside the grid must b selected.When i click again they should b deselected.Can any1 tell me how to accomplish this using client side code?(i mean in javascript)
i wrote a code like this
var isChecked = false;
function check()
{
isChecked = !isChecked;
var checkboxes = document.getElementsByTagName("INPUT");
var index;
for(index = 0; index < checkboxes.length; index++)
{
if(isChecked)
checkboxes[index].checked = true;
else
checkboxes[index].checked = false;
}
}
Check/Uncheck All
The above code is working 5n if the page has no other select controls(radiobutton,checkbox,listbox)outside the grid.
But i have one radiobutton control in my page.So when i click the href all the checkboxes inside the grid gets checked but the radiobutton also gets checked.That shoud not happen.How 2 accomplish this?

code.Is it possible to make any check that checkboxes are inside the grid and continue ,like
var isChecked = false;
function check()
{
isChecked = !isChecked;
var checkboxes = document.getElementsByTagName("INPUT");
//HERE I WANT TO CHECK CONDITION LIKE
if(document.getElementbyid("ct100_gvclust1")=="ct100_gvclust1")
// AND CONTINUE
var index;
for(index = 0; index <checkboxes.length;>{
if(isChecked)
checkboxes[index].checked = true;
else
checkboxes[index].checked = false;
}
}

Your tag
<a onclick="return check_uncheck1(this );" id="Check" runat="server" href="#">check</a>
and Javascript function is as like this
function check_uncheck1(Val)
{
var ValChecked = Val.checked;
var ValId = Val.id;
var frm = document.forms[0];
// Loop through all elements
for (i = 0; i < frm.length; i++)
{
if(frm.elements[i].checked == true)
{
frm.elements[i].checked=false;
}
else
{
frm.elements[i].checked=true;
}
}
}
