You can do like this:
<%=someVariable%>
However, if you use that your code quickly gets a mess of page level variables that you assign a vaule in one place and use in another place.
You don't have to use a label or textfield to display values in the page, you can use any server control you like.
A Literal control is useful if you want a control that does not add any html to what you put in it:
<asp:Literal id="objInfo" />
objInfo.Text = "Hello world!";
This will put the text "Hello world!" in the page where the literal control was. There is no span tag added around the text.
A PlaceHolder is useful for adding controls to the page:
<asp:PlaceHolder id="objContainer" />
objContainer.Controls.Add(new LiteralControl("Hello world!"));

It's amazing to see how much work some people will go through just to avoid a little bit of work.

i want to add a regular expression to validate the user input to be only in currency formate
thanks

Hi mate,
The best way forward for all those kind of validators is using a regular expression validator:
<asp:regularexpressionvalidator>
Look it up. It should be quite easy. There is a "ValidationExpression" property where you are supposed to input a complex expression which validates the input of Currency/Date/Time/Datetime/Numbers/Strings/Anything!
Visit http://regexlib.com.DisplayPatterns.aspx
It's a good site.

Can you please elaborate more on this? Like are you getting some exception, or you do not have webservice placed properly?
I did not get what exactly you are trying to say. :

I have written soap server and soap client using SoapSender and SoapReceiver class of WSE2.0. The soap server in console application while the soap client is in web application. The client requests the server. When the server replies some message to the client. This message is received in the client portion ie in the function Receive.
protected override void Receive(SoapEnvelope env)
{
}
Now the problem is, if i write some code inside the Receive function as
protected override void Receive(SoapEnvelope env)
{
//some code to extract message from the soapenvelope
WewForm1 wf=new WebForm1();
wr.Response.Redirect("WebForm2.aspx");
}
It won't redirect to page WebForm2.aspx. My objective is to take some action (either redirect to another page or just display the message received in the current page) when the message is received.
Could somebody tell me how to do this?
Thanks in advance.

In your custom class, you need to get reference to the Response object of the current HttpContext[^] instance and redirect the user to a new page.

Did you read the readme.txt file in the download to have an idea on how to build the source code and the runtime files? Also, you'll have to manually add the assembly to the Toolbox of the VS 2003.

I have a master page (MasterPage.master) and it's called by Default.aspx. Then I added a web user control (WebUserControl.ascx), I tested it all and everything was working great. I decided to add some color to the user control by way of CSS (StyleSheet.css), now I have problems. I don't want to add a link to the MasterPage head since not all pages using the master need the css. How do I programmatically have my WebUserControl.ascx.vb add a link tag to my page head? I think I explained this well, but if not just post your questions and I'll try to answer them. Thanks for any help offered.

Hi,
There are two ways available to resolve your issue.
1. Simple and easy way.
Put all your CSS styles in a style sheet and save into your project.
<your script> string should be:
<link href="your css path" type="text/css" rel="stylesheet" />
Add the following code to your control's page load event:
Page.ClientScript.RegisterClientScriptBlock(GetType(), <unique string identifier>, <your script>, false);
2. Some more work but efficient.
Create a function in for your master page like,
public void AddCssLink(string cssfile)
{
HtmlGenericControl styleCtrl = new HtmlGenericControl("link");
styleCtrl.Attributes.Add("href", "Styles/" + cssfile);
styleCtrl.Attributes.Add("rel", "stylesheet");
styleCtrl.Attributes.Add("type", "text/css");
Page.Header.Controls.add(styleCtrl);
}
from your control's page load event,
Master.AddCssLink("<your css file>");
Happy programming.

I think there are many ways to do what you want. You can programmatically access the Header[^] of the current page using the Page.Header[^] property and simply add the stylesheet. You can also do as someone said by injecting text or control (should use the HtmlLink Class instead of the generic one).

Hi
Am having few fields in my db table whose dbtype in SQL Server 2000 is money.Its of length 8 chars.
Now i want to display them in textbox for editing and saving.
Can anyone please tell me, if the length is as 8 whether it means the whole number part or the digits after the decimal point?(Say, i=12345678.0000--> whether the whole length of 'i' is 8 or only that '12345678' should be of length 8 chars).
I need this because i want to set the maximum length of the textbox such that
it should restrict the numeric entry to that of the Datatype's length in thw textbox and
if the user enters the 9th character as Whole number,it shouldnt allow.
Is there any explicit way of writing validation expression for this?
Please help me.
Thanx

As per my understanding, money can take upto
Monetary data values from -2^63 (-922,337,203,685,477.5808) through 2^63 - 1 (+922,337,203,685,477.5807), with accuracy to a ten-thousandth of a monetary unit.
So you need to restrict from user text box....

Thanx Amit
I need to know how to know to restrict that from Textbox.
Can you please help me for this?

I am using Money in my application. This is what I did.
The name of money columns were: mnColumnName
The datatype of money columns were: Int
The display formats in the TextBox/DataGrid were Currecy
Look up data formatting for ASP Controls. This was the easiest for me.
|
|

|

Thanx Friend
I am able to format the 'Money' data in the grid.
But i need to restrict the user from entering incorrect format.
For example,if he wants to enter '1244566.87' or '1244566',either of these should be allowed..
The whole number part(here '1244566') of maxlength as 8 characters and that of digits after decimal point(here '87') of 4 chars in maxlength.
Can anyone help me?
|
|
|
|
|
Let me get this straight..
You want to the user to input data which is from 1-8 character long AND 1-4 decimal places?
So the user CAN input: 12345678.1234 // 1.1 // 1 // 12345678 // 1.0
and CANNOT input : 0.1234 // 123456789 // 0
If that is correct, then just go to the website (http://regexlib.com/DisplayPatterns.aspx) and look for the correct regular expression for it. When you find the espression, use a <asp:RegularExpressionValidator>.
The thing is, I don't have the time to search for you. I did not have the same conditions as you did. I am trying to meet a deadline myself. Hope you find your answer.
