Hi All,
I'm tring to create a very simple composite control, consisting of a textbox and a label (and some html to style it..)
I have created it and at first it seemed to work, but now it appears I have missed out something fundamental.
I have a Text property in which I am setting the text property of the child text control and retreiving the same child property.
public string Text
{
get
{
EnsureChildControls();
return childTextBox.Text;
}
set
{
EnsureChildControls();
childTextBox.Text = value;
}
}
This works fine, unless on loading the page containing the control, I assign some text to the Text property. The text I assign appears in the child textbox fine, but when edited and attemped to save, it loses the new child textbox value, and reverts to the Text property as it was set on page load (or any other event that I use to populate it).
I'm guessing it's some kind of viewstate issue? Though this is the first time I have attempted a custom control of any sort and the help I've been looking up has led to me breaking it completely a number of time while trying various solutions.
If anyone has any idea what the problem is, then I'd appreciate your help as I'm running out of time to spend on it and don't want to have to abandon it because of deadlines.
Thanks in advance..

Where are you setting the default value for the textbox? In the Load event of your user control? Have you place that inside if(!IsPostBack) block?

Hi,
Thanks for the reply. Yes it was in the page load and even though I tried it on other events, I somehow never remembered to remove the onload version of the event, coupled with it not being in a (!Page.IsPostBack) block.
Having done that, it works just fine.
Thanks for pointing out the error, I'd spent so long looking for problems with the control, I didn't even think it could be with my page 
Thanks again
Mark

First of all your code is not understand at all. You need to post code with proper formatting.

Which Visual Studio version are you using ? is VS 2005 or Vs 2008 ? If VS 2005, please select AJAX Enabled web Site instead of Normal web site. Hope that may resolve your problem.
Thanks !

Hello all
I have 2 textboxes on my aspx site which I want to validate.
I want to make sure that the second textbox value is higher than the first one.
For example:
The user inputs 40 in the first textbox and 20 in the second.
This will give an error since 20 is less than 40.
But if the user types 40 and 60 it should work.
It should also be numbers only 
Any ideas?
Cheers!

What is the issue ? You can easily do it using JavaScript.

I am trying to download to a file on the client from my database, then confirm with an email, and record sucess / failure in the acoount access log. I generate the data, then do the following:
Response.Buffer = true;
Response.ContentType = "text/plain";
Response.AddHeader("content-disposition", "attachment;filename=" + user.UserName + ".AccountActivity.txt");
Response.BinaryWrite(System.Text.Encoding.ASCII.GetBytes(data.ToString()));
Response.Output.Flush();
And fine, I get the Save As dialog, the file saves.
Problem: If I do just as above, the full HTML for the client page is appended to the file, but the email and log are fine.
If I add Response.End(), the saved file is fine, no extra HTML there, but the email and log don't occur.
Is there a way to end the file transfer without ending the page?

If you dont close the response it will keep on adding htmls to the document. If you are only downloading a file, always close the Response.
do the email sending and log before you download if it affects the Response.
Now before you add ContentType, use Response.Clear
and then use your code to download the file.
