I* have so many controls for each application type. Setting visiblity for all the controls depending on application type will result in many lines of code. Insted of this approach, can we write the condition in aspx page like <% applicationtype > controls related to this type?
Thanks

No, I'm afraid you reach a point in life where you have to write actual code. How many lines can it take to show one of five different controls ?

Put the controls in a PlaceHolder and show/hide the one placeholder depending on condition.
|
|
|
|
|
you hjave to check condition for your application and based on that just show your controls.
e.g
protected void Page_Load(.....)<br />
{<br />
if(Condition of Application1)<br />
{<br />
} <br />
else if(Condition of Application2)<br />
{<br />
} <br />
.<br />
. <br />
} you can also Switch statement for that

Another way is to create different user controls for different applications types
And load one og these user controls at run time depending on our business logic
Thanks and Regards

Hi,
I'm new to web development and asp.net and can't figure this one out.
I've manually created a datatable in my dataset.xsd page and now I want to bind a gridview to that datatable. I need to do this so I can design the gridview at design time and manipulate it at runtime. I will be populating the datatable at runtime as well.
I can't see how to create a suitable datasource to link to the table?
Can someone point me in the right direction please. Obviously I'm coming from a forms background.
Thanks.

Hi,
using a Gridview "id" to bind the data. For example,
GridviewID.DataSource = ObjectDataTable;
GridviewID.DataBind();

So, I have an ashx called image upload. Inside I have code like this:
<br />
if ( context.Session[Base.SessionKeys.CurrentRequest] != null && context.Session[Base.SessionKeys.CaseId] != null)<br />
{<br />
if (int.TryParse(context.Session[Base.SessionKeys.CurrentRequest].ToString(), out currentRequest) && int.TryParse(context.Session[Base.SessionKeys.CaseId].ToString(), out caseID))<br />
{<br />
bool success = ImageUpload.UploadImage(context.Request.Files[key], currentRequest);<br />
This all works in IE, and the first line fails in FF, and in the debugger, I see that context.Session is empty. I've looked through the context object and can find no data in it whatsoever. Is there a trick here, or does this just not work in FF ?

Hello,
I am looking for a way to programatically edit the web.config file for the section below. Most importantly I will need to set the website login password to a certain value stored in the database. The password keeps changing in database whereas username remains the same. Can you please suggest a way this can be done using C# 2.0?
<authentication mode="Forms">
<forms loginurl="Login.aspx" timeout="60" protection="All">
<credentials passwordformat="Clear">
<user name="testuser" password="test123" />
</credentials>
</forms>
</authentication>
Thanks!

Just Check this Example
using System.Web.Configuration <br />
AuthenticationSection section =<br />
(AuthenticationSection) WebConfigurationManager.GetSection("system.web/authentication"); <br />
Label1.Text = section.Mode.ToString();
now you can able to solve your problem. for every settings of web.config there is a class on given name space. Asp.net Web Administration Tool Also used same API.
if you have any doubts ask me !!!

hi,
I am using the following code on Page_Load event of login page:
// Get the section.
AuthenticationSection section =
(AuthenticationSection)WebConfigurationManager.GetSection("system.web/authentication");
// Get the users collection.
FormsAuthenticationUserCollection formsAuthUserColl = section.Forms.Credentials.Users;
this.lblMsg.Text = formsAuthUserColl[0].Password;
formsAuthUserColl[0].Password. = "testuser";
The step that assigns current password to a label text works fine, however when I try to assign a password "testuser", the page fails at run-time with error "Exception Details: System.Configuration.ConfigurationErrorsException: The configuration is read only". I looked up Visual Studio 2005 documentation. It says Password property can be get or set. I have no clue why it errs out with read-only. Please advise.
Thanks.

Can some one tell me how to do this. Say I have created a Test website which has a default.aspx page. I have another folder called admin in the same root directory. Inside this folder i have a web page PostMessage.aspx which has a form with a Message text box and a dropdown box called visible which has only 2 values true or false. When the user clicks the Submit button I want the message in the text box to be displayed based on the visibility set on the drop down box to true or false. I actually want the message to be displayed in the default.aspx page which is in the same folder level like the Admin folder. How can I do this. I dont want to use a database for the time being.This is really urgent. Any sample code or tutorial will be great help. Thanks
Ex:
Test Website
Default.aspx
Admin Folder
PostMessage.aspx

1. The place where you save files here is not important.
2. You need to implement passing values between web pages.[^]
3. If you don't need to save message values in database which you write then you can leave option of database.

what is your SCOPE?

Gosh - are you serious ? You posted a bunch of code and said 'is this right'. No-one is going to trawl through your code with such a vague question. Why do you ask ? Is it working as expected ? What is your specific concern ?

Hi,
This is a rather obscure question but:
I was wondering if there was a way that when a user clicks a button to take data(either in a single or multiple datagrids, or arraylist etc,doesnt matter) and store it in a xls with multiple worksheets and then email it as an attachement? All automatically without using Response.ContentType = "application/ms-excel" or Response.ContentType = "application/vnd.ms-excel" or any other technique that will open up excel on the clients machine? Currently I use my sqlserver 2000 database(xp_smtp_sendmail stored procedure) to send the email.
So far my only idea is to use the server side technique of having excel installed on my web server. Create a template of the file I want on the server and having it fill in the relevant data each time it needs to be sent. Then send the absolute path as a parameter to my database that will then email it as an attachment.
My only other idea would be to use the client to create the xls file and then instead of having it open on the client, have it be sent to the server and then emailed?
Sorry if this is confusing, I will be happy to elaborate,
thanks,
Drew.

NM, I think i got this working using a 3rd party dll to save locally to xls and then used SmtpMail.Send.
Thanks for reading,
Drew.

A bit, what I don't understand is why you want to send a mail with the file.
If you don't want it opened on the client you can use Response.AppendHeader
Response.ContentType = "application/ms-excel"
Response.AppendHeader("Content-Disposition","attachment; filename=testfile.xls")
Response.TransmitFile( Server.MapPath("~/temp/testfile.xls"))
