Facing prob in retriving data .
When a item is selected from dropdown its index value goes in database , now when i want to retrive value in front end
i m not able to do tht as backend has int value and dropdown in list item contains string value
|
|
|
|
|
for dropdown there is a ValueField and TextField. hold the int value in ValueField and use dropdown.SelectedValue
hope this is what u asked?

You can convert that(string value) to Integer like this:
Convert.ToInt32("string value");

Hi!
I’m getting on buttonclick event following exception
Sys.Webforms.PageRequestManagerServerErrorException
When updatepanel is used in page.
Do you have any idea to solve this exception.
I tried a lot ,I got some ways to solve it Like
1) set EnablePartialRendering to false, but it is of no use bcoz whole page is getting refreshed ,to solve this issue only I’m using updatepanel.
<asp:scriptmanager id="ScriptManager1" runat="server" enablepartialrendering="false">
2)Set EnableEventVaildation=”false” not possible bcoz server side validation wont happen.
3)disabling cache in Role Manger in web.config
i put following code snippet in web.config
<rolemanager enabled="true" cacherolesincookie="false">
<providers>
<add
name="SQLOLEDB"
="" type="System.Web.Security.SqlRoleProvider" connectionstringname="ConnectionString" applicationname="MClosetURL">
but problem didnt get solved
4) I used javascript to catch the exception at client side in script tag in aspx page , In this case I’m not getting exception but nothing is happening after that ,server side click is not getting fired
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
if (args.get_error() != undefined)
{
var errorMessage;
if (args.get_response().get_statusCode() == '12031' || args.get_response().get_statusCode()=='12030' || args.get_response().get_statusCode() == '405')
{
args.set_errorHandled(true);
}
else
{
}
}
}

This block should be below the ScriptManager. Check whether you placed it in the right place.

good morning venkatesh!!
Thank you for replying me, after much longer wait finally i got reply from someone. Actually the code I have put in my page is working
bcoz sys.webforms.... exception is not coming but server side event is not getting fired afte button click, Postback is not happening at all.
I have used script manager in master page and written code in script in the page
in which that error is comming.
Even if i tried putting this script below script manager in master page but nothng different happened.
I Think in the if condition of code below
is it enough to have statement args.set_errorHandled(true);
or something more is needed.
Pls guide I want button click event at server side should get fired after exception is handled by the following code which is not happening in my page .
thanks a lot again!
have a very nice day!!
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
if (args.get_error() != undefined)
{
var errorMessage;
if (args.get_response().get_statusCode() == '12031' || args.get_response().get_statusCode()=='12030' || args.get_response().get_statusCode() == '405')
{
args.set_errorHandled(true);
}
else
{
}
}
}

I want to draw your attention to the behaviour of a custom dropdown combobox such as one on:
http://www.codeproject.com/aspnet/ComboAdjustDropDownWidth.asp[^]
when the page containing it is loaded on a custom browser created using the WebBrowser Control that comes with Microsoft Visual Studio 2005. It is impossible to scroll using the vertical scrollbar. When you click on the scrollbar with an intention to scroll, it just closes. I tried this from a custom browser I created and also on another by Thomas Maxwell on Planet Source Code:
http://www.planet-source-code.com/vb/scripts/ShowCode.asp?lngWId=10&txtCodeId=5484[^]
with the same result.
On IE, its scrolling ability is OK. Is it possible that Microsoft's WebBrowser control might have some deficiencies?

Hello everyone,
How can i make fastest website or program in ASP.NET
wht should include to make fastest website or program
Thnx in advance
|
|
|
|
|
fastest...does not have any tricks...
if you follow basic programming practices your application/website will be fast.
look into some optimisation techniques.......
some tips.
1) make sure you use SP and no SQL statements on code behind.
2) and in SP's make sure there are less sub queries, use joins instead. use profiler and see how much time does it take for execution.
3) inside code behing take care of all the loops and functions.
4) use javascript/ajax
5) avoid repeatable codes......
etc etc..........

ChildWindow = window.open('frmCalender.aspx?FormName=' + document.forms[0].name + '&CtrlName=' + CtrlName, "PopUpCalendar", "width=200,height=210,toolbars=no,scrollbars=no,status=no,resizable=no,titlebar=no,top=300,left=350");

Hey all,
Can some kind sole please tell me how I write to a panel (using c# in .net)
from a page load event (the page load is irrelevant, it could be any event).
Basically I have a list of links being created as the page loads and I want them to be in one of two panels and I can't seem to find the answer anywhere.
any help will be appreciated

ok, thanks for that but its not where to write the code thats the problem.
Its what to write that I can't seemto find.
I have a panel called Panel1 and a panel called Panel2.
For layout reasons I have placed my web controls in Panel2 using VS2005, not a problem there.
When I load the page I am using the .aspx.cs file to generate a loop of files in a folder and write the list of them inside Panel1.
if I just response.write the it'll always appear at the top left of my page above my header etc, so I want to specifically write into Panel.
I tried out of desperation to write the whole page in the code behind page (everything between the body tags!) but of course then my webcontrols don't yet exist for VS to build the site.
Any other suggestions pleease?
thanks
mark

Hi guys and gals.
I have a crystal report that makes use of an ado.net dataset. The problem is that this dataset is getting filled at run-time only. I dont know if I am just stupid, but I cant seem to set the datasource at runtime and bind the data to the report. Please help if someone know how to do this.

Elizma
