How do I programmatically add an internal style tag to the header in an ASP.NET page? Eg. like...
<head><br />
<title>Title</title><br />
<style type="text/css"><br />
<br />
p<br />
{<br />
font-size: 70%;<br />
margin-bottom: 4px;<br />
font-family: Verdana, Sans-Serif;<br />
}<br />
<br />
</style><br />
</head>
I want to programmatically add/manipulate the <style type="text/css"> tag from the code behind. Any ideas?

Use a FileUpload control.
---
b { font-weight: normal; }
|
|
|
|
|
Where can I find one of those?

System.Web.UI.WebControls.FileUpload
---
b { font-weight: normal; }

Is fileupload available in .net 1.1?

|
|
|

Yes. It is available in the Visual Studio's HTML Controls (toolbox). When you add it just remember to make it runat=server.
When the page postbacks you can access the file by fileUpload1.postedFile, if i'm not mistaken.

This forum is open source so you can download it.
A couple versions available, see David Wulff's version which seems to be complete http://www.codeproject.com/asp/aspforum-n-membersys.asp[^]
Otherwise just do a search on CodeProject and you can find plenty stuff.

Hi,
I am trying to access its datasouce property after the gridview has been databind, but the value is always null.
here is the example I did:
in button1_click:
...
GridView1.DataSource = dataTable1;
GridView1.DataBind();
....
in button2_click:
....
DataTable dt = GridView1.DataSource;
....
The value of dt in button2_Click is always null. I read about that the data source needs to be bound to the GridView control only when the page is first loaded. Thereafter, the values are stored in view state.
How to access ViewState to get the data source property?
Is there anybody know about it?
Thanks in advance!

The datasource isn't maintained in viewstate as a raw dataset.
|

Datagrid is stored in a table, which is stored in ViewState.
ViewState doesn't store the DataTable. only serialized data can be stored in viewstate.

I think you may just have to cast the datasource to a datatable
DataTable dt = (DataTable)GridView1.DataSource;
|
|
|
|
|
I did try that. But it still is null..
|
|
|
|
|
I saved the datatable into viewstate when the GridView is binded. Then, when I want to use it, I just get it from viewState...
Do you think it could cause any issue, like perfomance?
|
|
|
|
|
Storing multiple rows or even a single row with considerable no. of columns is going to create an impact on the page's performance.
|
|
|
|
|
to dynamically add rows into GridView without really adding records into database, so that user can add as many rows as he wants, and dump all the rows into db at once.
Is there any other ideas to do it?
|
|
|
|
|
Remember that you're actually storing the datatable twice (in a sense). It's values are being stored in the viewstate inside the binded control, and you are storing it, as a whole, also.
With minimal rows, this would be fine. But at the table grows, the viewstate grows twice as fast and could lead to major memory headaches down the road.
You also have the option of turning off viewstate for the binded control. There are several articles explaining this process.

Need support....
I d'like to copy a file aspnetdb.mdf (ms sql 2005 db) created with microsoft visual web developer 2005 to my websites host. I have already a website copied with asp 2.0 sites to my host without problems.
But now it is the first time that i try to copy a ms sql 2005 db. The aspnetdb.mdf works fine on my local PC. Now the provider told me, that i have to create a db Login in his Control Panel for accessing sql 2005 server.
I have to define a Login user name and a password. And later a sql 2005 db.
My Problem: Why should i create an new sql 2005 db on the host server. I d'like to transfer my local sql 2005 db (microsoft visual web developer 2005) to the host?
What changes are necessary in the web.config:
The definition on my local pc:
<connectionStrings>
<add name="ASPNETDBConnectionString1" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\ASPNETDB.MDF;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
</connectionStrings>
Do I have to add a user id and a password?
What connection string is necessary to access to my host sql server?
Do you know some recommended tutorials? I could not see a solution in the following video:
http://www.asp.net/learn/videos/view.aspx?tabid=63&id=5
Thanks a lot for your support.
You see -- I am a beginner....
Best regards

The provider might not have a way or the time to import SQL Express database into SQL Server 2005 Database. The database created by the provider is usually blank and you are required to re-create all the necessary objects through the provided interface

I'm creating an on-line application that has a submit button. When submit action occurs, the form data is then submitted to a Positional Flat File. The reason why I have to use flat file is because the company that we outsourced for our recruiting database uses flat file text to input into the database. I have no idea how to submit form data to a positional flat file. I have to flat file template with the record lengths. Can anyone help?
|
|
|
|
|
just create a sting of the record length. Then place each item in the string in the respective position. Another option is to pad each item to its max length, they append it to create the record.
You may want to consider creating a simple class that contains each field, then a create method to concatenate the individual fields to the record length.

Is there code snippets that I can see to help me get started? Any tutorials or examples?
