Hi all,
i have a aspx:text box, aspx:list box and an html button in my webform and when the user type something in the text box and click this value will be added to the list box, i have used javascript for this. now my problem is that, when i tried to take the items in the listbox in csharp code ( in submit button click), i dont get any value ( listbox.items.count shows zero). How can i get the values of this list box at server side code that i have populated at the client side? anyone please help me.
Thanks in Advance...

function AddToList()
{
optn = new Option();
optn.text = document.forms[0].txtMonth.value;
optn.value = optn.text;
document.forms[0].listBox1.options.add(optn);
}
this is the code to add items to list box from textboc txtMonth.

1) I try you code and it doesn't work.
2)
Protected Sub Submit1_ServerClick(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit1.ServerClick
MsgBox(listBox1.SelectedItem.Text)
End Sub
I hope that I understood what you meant

Hey all! ive been using ASP Ajax Beta 2 now for a few days and its already driving me crazy!!!
First of all, ill be happily dragging controls onto the my design view (scriptmanager, updatepanel, progress and so on) and it all looks good...
I switch to source view and all my ajax controls have the "red line of doom" and my error list says things like:
Error 20 Element 'ScriptManager' is not a known element. This can occur if there is a compilation error in the Web site.....
Switch back to Design view and it renders ok and builds propperly! And the other problem ive noticed is if i change any properties in design view of any control, and switch back to Source view it has screwed all the markup code up! It does things like put all the code on one line and make it very difficult to work with and i have to tab it all out again!
Does anyone know why its doing this and any solutions?

Hi Guys,
I wrote an image httphandler that works 60% of the time.
I'm trying to render 10 images on 1 page... ex. MyImage.aspx?id=1 , MyImage.aspx?id=2 etc.
Every now and again (when I'm lucky) all 10 images load, other times only 6 or 5 or some random number of images load.
The ProcessRequest method executes the same amount of random times. 
Is there some setting which I should change in the web.config to handle a few simultaneous requests??
Or whats going on??

Hi friends,
I have to upload and download .txt or .doc file on server.
I uploaded files properly.
But when downloading files, if file is .doc file then it get downloaded correctly,and if I download .txt file that saved .txt file containing some html code.
If I cheched it on server directly it is showing .txt without html code.
This is my code for download.
Response.Clear()
Response.ContentType = "application/octet-stream"
Response.AddHeader("Content-Disposition", _
"attachment; filename=""" & filename & """")
Response.Flush()
Response.WriteFile(filepath)
Why this is so.
Please help me.........thanks in advance.

Hi
I have started using the GridView and SqlDataSource in ASP.NET 2.0. It makes connecting and databinding very easy. But is it not moving away from the n-tier approach, where the presentation layer does not connect directly with the datalayer?

you can either do it all client side and use the onblur event on A and B to call a function that checks both A an B for values and if they have values fills C with their sum or you can do it clientside using the autopostback="true" and then using the OnTextChanged event to make the same operations.

you can use javscript function when you are setting focus to your third textbox.
<asp:textbox .... onFocus="javascript:alert('hello');>
use your javascript function insteadof alert();

write :
<script>
function addTwoTextbox
{
document.getElementById("Textbox3").value =
document.getElementById("Textbox1").value + document.getElementById("Textbox2").value;
}
</script>
and call addTwoTextbox() fn where you declared textbox like :
<asp:textbox id=... runat=... onFocus="javascript:addTwoTextbox();">
