1 - Handle the click event.
2 - Write query to delete.

You need to contact them and ask about the APIs they provide.

Hi,I want to access a session variable of one application from another web application.How can I achieve that?

you can't, not without some sort of intermediary, like a service on the server that hosts them both, to store/pass the value. Of course, your next problem is, which session on app a, is related to the session I am accessing in app b, I assume there's a username the two apps have in common or similar that you can use for this.

It seems that your are accessing the file PrjDailUpdatesExtElt in the button click event handler...Make sure that the file actually exists..Also see FileModes if you are writing to the file...

Hi,
I am working with asp.net page.I have a drop down list which displays values(like 1,2,3,4....).Now what i want is based on these values we must generate a textbox.
E.g: Dropdown list value = 1 1 Textbox must be generated.
value = 2 2 Textboxes must be generated...So on...
I have added a place holder and tried with Events of Dropdown List...
But i am unable to generate any text boxes...Please help
Thanks in Advance

First set the AutoPostBack property True for DropDownlist and handle the SelectedIndexChange Event.
void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
int txtCount = int.Parse(DropDownList1.SelectedValue)
for(int i=0;i<;txtcount;i++; )
{
TextBox txtBox = new TextBox()
....
.....
placeHolder.Controls.Add(txtBox)
}
}

That approach will generate the texboxes, but since it is created after viewstate events, ASP.NET will not maintain viewstate for it. Thus the values entered in the texboxes will not be persisted across postback.

Thanks for correcting my mistake.... I haven't try that way so I wasn't sure just give him a hint.

Think textbox doesnt use viewstate for maintaining the text across postbacks
Even if the viewstate is false,text will be still maintained during postbacks
Correct me if i am wrong.
