"Replace" not replacing..

[eramgarden]

If I use this to replace an empty string with Zero, it doesnt work. The value is "Nothing"

 

Dim test = Replace(CType(e.Item.FindControl("txtForcast"), TextBox).Text(), "", 0)

 

Why?? I used If-else instead but wondering why that doesnt work..

what? this doesnt work -

e.Item.FindControl("txtForecast").Text = e.Item.FindControl.("txtForecast").Text.Replace("","0")

 

forget the old vb6 way of doing things!!!

Still doesnt work, I get:

 

String cannot be of zero length. Parameter name: oldValue

LOL - you're trying to replace empty string with something? The Replace function/method is meant to replace a valid string inside of another string with something else. But you can't say "replace nothing with something".

 

I think in your case, the most elegant solution is to just do an If. If you like readability:

If e.Item.FindControl("txtForecast").Text = String.Empty Then

e.Item.FindControl("txtForecast").Text = "0"

End If

 

Or if you want "performance":

If e.Item.FindControl("txtForecast").Text.Lenght = 0 Then

e.Item.FindControl("txtForecast").Text = "0"

End If

 

Of course, you might want to put the reference e.Item.FindControl("txtForecast") into a variable for readability.
