Hi there! I am a hobby code writer. I am new to C# here. The above is the code I try to generate but having problem. When I try to debug it say that "Invalid expression term 'else'". I am also unable to try "End if" in the intellisense. Can anyone tell me what is wrong.............................................please
if..then..else

the "{" and "}" represent code blocks.
"if" doesn't take a "then" in c#
";" is the end of a statement therefore you dont need a ";" at the end of the "if" line becaues the statement is not complete, it needs the code block. same thing with the "else" that is unless you want the "if" and/or "else" to have an empty block.
protected void Button1_Click(object sender, EventArgs e)
{
if (DetailsView1.Visible == false)
{
Button1.Text = "Update";
DetailsView1.Visible = true;
}
else
{
Button1.Text = "New";
DetailsView1.Visible = false;
}
}
Also, you only need the "{" and "}" in the if/else code blocks if the code blocks are multi statement. If single statement you can follow jsut with the statement.
protected void Button1_Click(object sender, EventArgs e)
{
if (DetailsView1.Visible == false)
DoSomething();
else
DoSomethingElse();
}
you can even keep them on the same line, but this is a matter of style (some don't like it)
if (DetailsView1.Visible == false) DoSomething();
else DoSomethingElse();

Oh I see.
I now know where I've been (completely) wrong.
Thank you so much.

Hi Yok,
It looks like you're trying to mix syntax learned in VB into something intended for C#.
Grouping multi-line statements or functions typically require curly-brackets in C# - there is no "end" keyword in C#. So try the following:
if(DetailsView1.Visible == false){
}else{
}
"C" style syntax is much different than "basic", thus the feuds that often take place surrounding the different languages :-)
Good luck, and happy coding.
