I dynamically created an image (imageA), what I require is onclick event another image (imageB) should display and save the imageA id in string (which later I store in a dataset).

My question is how do I change and save the imageA id? , JavaScript can handle onclick event but don’t know how it handle in <asp:placeholder>

Here is a code

default.aspx

<asp:PlaceHolder runat="server" ID="image_placeholder"></asp:PlaceHolder>

default.aspx.vb

Dim imageA As System.Web.UI.WebControls.Image = New System.Web.UI.WebControls.Image()

imageA.ID = "imageA"

imageA.ImageUrl = "Box1.gif"

image_placeholder.Controls.Add(imageA)

Thanks In Advance

It shouldn't be possible. In order to display a webpage within a browser, it will have to know two things:

1) What page do you want
2) Where is that page

"Home.aspx" is the name of the page. "Localhost" is the place where that page resides.

"Localhost" is the domainname for your local computer. You could change that in the hosts-file, to get something like "http://mycomputer/home.aspx".

You could also set the default page to "home.aspx", that's a setting in IIS. That would give you an address like "http://mycomputer/".

Surely the better way would be to just have a textbox and then let the user write down their info into that and then update the database that way.

Telerik has a combo box in its rad controls. They cost about $1000 per person.

I didn't get any requirements for the signature

Timer controls work well on an asp.net page. As a web page refreshes each time it is back, You should declare the time control as a static attribute of the page, as well as the timer event handler.

protected System.Timers.Timer timer1; <br />
private int test; <br />
<br />
protected void Page_Load(object sender, System.EventArgs e) <br />
{ <br />
// Put user code to initialize the page here <br />
test = 1; <br />
<br />
timer1.Interval = 1000; <br />
timer1.Start(); <br />
<br />
timer1.Enabled = true; <br />
<br />
} <br />
<br />
<br />
<br />
private void timer1_Elapsed(object sender, System.Timers.ElapsedEventArgs e) <br />
{ <br />
<br />
test = test+1; <br />
<br />
lblCounter.Text = "count:"+test; <br />
<br />
} <br />
<br />

No, they really don't. In your example every user will have the same timer Hmmm | :|

A javascript timer will work, such as the one within the AJAX Toolkit.

Please consider your answer to questions before posting them, if you're unsure its probably better to not bother posting.

I'm never 100% sure..

..even an answer that isn't 100% can give you a pointer in the right direction. Sometimes such an answer becomes the base for an entire discussion. It does happen that we generate an adequate answer as a group, because we interact.

FWIW; you can make the code user-specific Smile | :)

And a stupid answer like the one given can lead you down the garden path, round the block and back again. In addition, im 99% sure the OP wanted a timer on the client not the server. He may not have specified that, but after years of answering questions on forums like CP, you can generally tell.

Not with a static Timer you cant. You may wish to read up on the static keyword.

Will do. I assumed that the component is simply shared among the users. Am I mistaken?

FilteredTextBox for invalid chars as (@%$&*)

17-Sep-08 2:25

One problem I found on the timer control is that if I had code running on page load and the timer was set to update say eevry minute the code on the page load would run as well.
This is a big drawback if you are using postback scripts etc

Try using a regex validator to check chars.

Hello,
U can assign a regularexpression validator to the text box.
regularexpression can be "^[a-zA-Z0-9]$"
try this.

Hello, You can check on client side also.
using textchanged event of that textbox.
call a function on textchange and on the function check the keychar
if it is within your range then text will be added otherwise it return false, means character not appended on that textbox. Only valid char will appears.
Try to make a javascript function..
Best of luck. Blush | :O
