That's a bit vague. Why do you need a project idea? For what purpose is the project? If it is for your own education, what things are you interested in?

How about a Mars Rover control panel in asp.net
That should be challenging.

Hi,
I'm using a pop-up window to display a contact form. This same window is re-used to contact various departments.
So for example a user clicks a link to contact Department 1, a window pops up with a contact form. Now the user changes their mind and clicks to contact Dept 2. The form is reloaded with the necessary contact details.
The problem here is that the pop-up window is pushed to the background due to the main page doing a postback. I need to be able to bring the pop-up window back to the foreground when this happens / when the content of the pop-up window is reloaded / refreshed.
Can anyone help me with this please?
Thanks!

My Suggestion is better go for AJAX technology instead of posting back your main page.Even if the cotent of the pop window is reloaded it will still remain in the front.There will not be any dependency between Main page and Pop up window.

Put a repeater into your page, define how each row looks and then bind your data from db to the repeater.

a repeater will be a good choice for ur problem. datlist is used if u need to make changes to the data. since u just need some links to another page, it is always better to use repeater.

Hi,
Yes repeater is an good option.
You can do it as:
Code:
qrystr = "select link_text,url from url_links"
adaplnk = New SqlDataAdapter(qrystr, conn)
adaplnk.Fill(drlnk)
y = drlnk.Rows.Count
Repeater2.DataSource = drlnk
Repeater2.DataBind()
Design:
<%if y> 0 then%>
< asp:repeater id="Repeater2" runat="server" >
< ItemTemplate >
< a target="_blank" href="<%#DataBinder.Eval(Container.DataItem, "url")%>" class="popurl" > < IMG height="11" src="images foldername/<%#DataBinder.Eval(Container.DataItem, "link_text")%>" width="14" border="0 >< /a >< /ItemTemplate >
< /asp:repeater >
<%end if%>

In ASP.NET if a application is using Form Authentication ,and if the user skips the login page and directly tries to browse the inner page using its link what will happen?Will the authentication be violated by the user?
|
|
|
|
|
The user will be redirected to login page as in Web.config
|
|
|
|
|
Hi,
If in the web.config file, you set authentication to Forms and LoginUrl to Login.aspx....and authorization deny users "?" ......Then client cannot go to other page without first going to Login.aspx.
Hope helped.
Happy Programming.

I have a simple VB ASP.NET 2.0 page with a Button and a Label.
The Label text is "0". For each click of the button (btnAdd), it should
increment the Label text by 1.
The code:
Protected Sub btnAdd_Click(...) Handles btnAdd.Click<br />
Trace.Warn("Before add: " & lblCounter.Text)<br />
lblCounter.Text = (Int32.Parse(lblCounter.Text) + 1).ToString<br />
Trace.Warn("After add: " & lblCounter.Text)<br />
End Sub<br />
However, each time I click the button, the label always increase by 2 instead of the expected 1. What's the problem area?
I tried to debug using Trace.
I get the following result from the trace:
Begin Raise PostBackEvent
Before add: 0
After add: 1
Before add: 1
After add: 2
End Raise PostBackEvent
Is this signifies PostBack event is being run twice per button click?
How to solve it?
Thanks for your assistance.

Protected Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
'Label1.Text = Val(Label1.Text) + 1
Label1.Text = (Int32.Parse(Label1.Text) + 1).ToString
End Sub

Hi,
I've had similar problems in the past with updating data. Its not a 'problem' as such that can be solved and sounds more like a case of how and when you are binding data / incrementing the values.
In most cases it is to do with the fact that you're increment code is being called twice. How and when this occurrs i couldnt tell you because it is of course specific to your page / code.
The simplest - although perhaps most time consuming solution - is to rebuild the page from scratch. Implement the incremental code at the earliest of opportunities whilst there is minimal additional code associated with the page. This will make it much easier to work out exactly what is going on.
Hope this helps.

I'd also make sure that there isn't another delegate registered on the page for that event, could force it to call twice.
