I have a form with 2 fields, say "name" and "tel" of a person.
My visitors may need to add from 1 to n persons
I need to display only fields for 1 record and a button that adds omre records' fields on the runtime as visitors' needs
I can use javascript code to create html form fields on the fly
Is there any better idea using ASP.NET powerfull controls?

Hi there. You are probably best off using javascript as it will give your visitors the best experience in their browsers.
You could do it server-side by dynamically adding the text box controls in your Page_Load - something like Placeholder1.Controls.Add(tb) but as a user, I'd prefer the javascript route to avoid the server postbacks.

You could use a GridView, adding an empty record each time the user clicks the Add button. Of course the new row would need to be in edit mode. Unless you use an AjaxPanel this will produce postback flashing of course.

Another way is create a user control having the fields that you want to add after clicking (2 text boxex)
Now add a repeater to your page bind this user control to repeater
Thanks and Regards

Hi everyone,
I am developing an asp.net webpage where i would like the user to play a game.
The game is moving a car for every time tick.
I got the timer function and made the movement in javascript.
Now my problem is that how to call the javascript function from my timer which i have in asp ajax.
Love to hear any advise.
Thanking you
|

|

I think you need to reverse your logic. The timer should be in the JavaScript, and it should make out of band calls to your page class, rather than you page class trying to communicate with the JavaScript.

As you are using .Net 1.1, and don't have the option of theming, the easiest way would be to have multiple stylesheets, and use the QueryString variable to determine which stylesheet to link to.
In the <head> section of your aspx page, add a standard link element that links to your default CSS file. Give it an ID and mark it to runat="server". In your code-behind file, make sure the link element is declared as type System.Web.UI.HtmlControls.HtmlLink along with the other page controls.
Then, when the page loads you can simply check the QueryString to see which stylesheet to use. If you have a valid stylesheet then simply set your declared link elements href property.
Hope this helps...

I have a gridview that is in a webpart, , one column is a checkbox column.
in the grid_row created event I set the proberties for the check box like so:
private void Grid_RowCreated(object sender, GridViewRowEventArgs args)<br />
{ TableCell cell;<br />
CheckBoxField column;<br />
CheckBox checkBox;<br />
if (args.Row.RowType == DataControlRowType.DataRow)<br />
{ for (int i = 0; i < args.Row.Cells.Count; i++)<br />
{ cell = args.Row.Cells[i];<br />
column = Grid.Columns[i] as CheckBoxField;<br />
<br />
if (column != null)<br />
{ foreach (System.Web.UI.Control ctl in cell.Controls)<br />
{ checkBox = ctl as CheckBox;<br />
if (checkBox != null)<br />
{ CaseCategory dataObj = args.Row.DataItem as CaseCategory;<br />
if (dataObj != null)<br />
{<br />
checkBox.ID = dataObj.CategoryId.ToString(System.Globalization.CultureInfo.InvariantCulture);<br />
}<br />
checkBox.AutoPostBack = true;<br />
checkBox.EnableViewState = true;<br />
checkBox.CheckedChanged +=new EventHandler(checkBox_CheckedChanged);<br />
checkBox.Enabled = true; <br />
} } } } } }
before converting this code worked perfectly, after the event does not get fired. I have removed the scriptmanager and related controls from the page, with no effect.
does anyone have any ideas what is going wrong, or how to fix it?

Hello, I have created an ASP.NET web user control which has only one ImageButton. I have added 2 new properties to the class called OnMouseOverImage, OnMouseOutImage, these are both strings with getters and setters. Is it possible to make the designer open the file browser dialog when i click on these properties in the designer? Do I have to add some code, set some properties?..i don't know. I want them to behave like the PostbackURL or NavigateURL or ImageURL in the standard ASP classes for example. If this is possible, then please tell me how. 
Uh...isn't there anybody who knows it? i didn't find anything about this problem.

Hi,
You should be able to accomplish this by marking your property with the required Editor attributes. By default all properties appear as straight text editable fields within the designer. By associating your property with an Editor that inherits from UITypeEditor, you should be able to achieve this. For example:
Reference the following namespaces within your class:
using System.ComponentModel;<br />
using System.Windows.Forms.Design;<br />
using System.Design;<br />
using System.Drawing.Design;
Mark your public property with the following:
Editor(typeof(FileNameEditor), typeof(UITypeEditor))
There are a number of pre-built editors that you could utilise so it may be worth having a play and seeing which works best.

do you have to write something like this?
[Editor(typeof(FileNameEditor), typeof(UITypeEditor))]
public string PostbackURL
{
get
{
return ImageButton.PostBackUrl;
}
set
{
ImageButton.PostBackUrl = value;
}
}
It doesn't work, probably i'm doing something wrong.

I am developing a point-of-sales software on asp.net. When sending crystal
report to client browser for printing cash bill, browser always popup Acrobat Reader report viewer at client browser before bill can be printed.
Anyway for asp.net to send report directly to printer at client side? Too
many steps for cashier to get printed bills makes the system unfavorable.
):

|
|

ASP.NET works on the server and sends HTML to the browser. It don't have any access to the printer.

What about window.print()?

It's java script and won't send print command directly to printer. It will open the print dialog box.

Oh yes it will open printer dialog box. sorry that i forgot he want print directly. i think the window.print is the only way to print something from client side
