In my form, I have two dropdownists called Countries and States which are dynamically generating. These controls are generating only at the run time and the Country dropdown gets loaded for the first time.
I have written code for the SelectedIndexchanged of the Country dropdown so that the corresponding States also will get updated in the States dropdownlists. These are all working fine.
My issue is these are working in a Postback condition. Can I use an UpdatePanel dynamically so that the User doesn't get an impression that the page is actually posting back. Any idea how to create the Update panels dynamically so as to include both the dropdownlists and populate without a postback? Thanks for any help.

How user is getting that page is posting back? A post-back and page refresh is not same. Are you saying your page is refreshing?
Not sure I got you correctly.

Thank you for the immediate response. Sorry that I didn't mention clearly the issue.
Page is not refreshing. It is posting back, means when the User Selects a country from the CountryDropdownlist, the corresponding States are populated from sql database by passing the CountryId.
I made the AutoPostBack property of Country to True so that it posts back to the server when the index changed. Hope this is clear now.

Well, how can the second dropdown be filled without a post-back? AFAIK, you can't avoid page posting back. BTW, what is wrong by doing so and why are you trying to prevent it?
|
|
|
|

You are right. The second dropdown is filled with a post-back only. But while using the UpdatePanel, the user will not get the feeling that the page is actually posting back. This will help him to enter the data in other controls and need not wait for the page to be reloaded.

If updatepanel is used only for filling the dropdowns without page refresh, why don't you try Cascading Dropdown[^]?

We can add update panels dynamically. Please refer the following code sample(working):
Note: This is a Sample code

Hi,
I am sending message to multiple user. I am using forloop and using this for loop it takes the numbers one by one from the textfile and send the sms.
but it takes to much time for 10 numbers at a time.
Is it possible with Multithread or Webservices ? Or any other solution.
Thanks
sjs

How you are sending SMS
Are you using a SMS Gateway
OR
Sending SMS from mobile using symbian API's
|
|
|
|
|
|
Then you need to check out with Gateway Documentation, whether they allow comma separated list in to field
|
|
|
|
|
Yes. Gateway supports comma Separate list
|
|
|
|
|
So then send it comma separated list 
|
|
|
|
|
then, where is the problem, send the comma separated list 
|

Hi All,
I am creating a custom server control for multiselection drop down list. This control contains AspxEditButton, check box list and panel. AspxEditButton and check box list are placed in that panel. I have to display selected items from check box list to AspxEditButton at the time of MouseOut from panel. Can I use code as follows at WebControl1.cs,
_panel.Attributes.Add("onmouseout", "Javascript:CtrlLeave(); ");
And can I write CtrlLeave() javascript function at WebControl1.cs How can I write a javascript function at WebControl1.cs?
Regards,
Anu

Just render the JS function along with the control. A better way would be to use embedded resources. I have explained it here[^]. Please take a look at that.

hi all,
My application is on one drive and i want to locate another file or use a file from another drive.How can i do this.i am using asp.net and c#.
Thanks in advance...

You can't. ASP.NET will have access only in the website area. It can't access files from some other drive.

Hi everebody,
After we applied the security update that is described in security bulletin MS07-040 - our ASP.NET 2.0 application started showing garbage data.
I read this http://support.microsoft.com/kb/940521/en-us[^] and suspecting that this is happening beacuse of this.
If we refresh the page then the garbage characters are removed.
Please help if you could suggest anything.
Thanks much.
Regards

Hi, I am still a newbie in ASP.net development,
I try to learn about nested master page, and I got this problem
Cannot find ContentPlaceHolder 'ContentPlaceHolderUser' in the master page '/OnlinePrayer/MasterPage/AdminUser.master'
I have done some research in internet, but until now, I have not got the right solutions.
basically, in my website, there are 2 master page : AdminUser.master and User.master
and AdminUser is child of User,
In User.Master , I've got this following code
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="User.master.cs" Inherits="MasterPage_User" %>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>UserPage</title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:contentplaceholder id="ContentPlaceHolderUser" runat="server">
</asp:contentplaceholder>
</div>
</form>
</body>
</html>
and in AdminUser.master, i've got this code
<%@ Master Language="C#" MasterPageFile="~/MasterPage/User.master" AutoEventWireup="true" CodeFile="AdminUser.master.cs" Inherits="MasterPage_AdminUser" %>
<asp:Content ID= "SubContent1" contentplaceholderid="ContentPlaceHolderUser" runat="server">
</asp:Content>
I thought that I had define ContentPlaceHolderUser in User.Master, but I dunno why I still got this error? in Admin.Master
I would be grateful if you could give me feedbacks about my problems,
thanks

Hi,I hope I understand your problem in a correct way.
Here iam giving you the code for two nested master pages and an aspx page which uses these master pages.
try it out.
1.User.master as follows.
<title>Title
Some content in main master page
<asp:contentplaceholder id="ContentPlaceHolder1" xmlns:asp="#unknown">
runat="server">
Child master page will be placed here...
2.AdminUser.Master as follows(child master page for User as you said and here the Master page file is User.Master).
<asp:content id="Content1" runat="server" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder1">
This is child master page
| <asp:contentplaceholder id="ContentPlaceHolder1">
runat="server" EnableViewState="true">
Contents of pages...
Content in Child master page.
<asp:contentplaceholder id="ContentPlaceHolder2">
runat="server" EnableViewState="true">
Contents of pages.
|
3.Default.aspx page which uses the master page.(Master Page file is AdminUser.Master)
<asp:content id="Content1" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
<asp:content id="Content2" xmlns:asp="#unknown">
ContentPlaceHolderID="ContentPlaceHolder2" runat="Server">
Hope it helps.

I am trying to find a way to display the contents of multiline textbox on a print preview page to display and print the entire contents of what the user has typed in. Once the user types in data in the multiline textbox, the data is stored in a SQL database and then retrieved to be displayed on a print preview page to be printed? Any ideas? Sorry if the question is a little easy for some of you but I am a newbie to C# and .Net prgramming. Thanks is advance.
