How to use remove string method in textbox in C#

C#

Hi,

I have an text box called planned hours which accepts hours. It will allow only numeric and decimal values.And only single decimal is allowed.
So example the valid values are:

1.5-- ok
1-- ok
12.5-- ok
12 -- ok
12.0-- ok
1.0-- ok

So the max length of textbox is 4.

I have two screens:
1.Create plan
2.View plan

while creating the plan when i pass planned hour text box value as 12.5, in plan view screen, the planned hour value is displayed correctly(i.e 12.5) and zero is not appended after 5

but when i pass planned hour text box value as 1.5 or 1, in plan view screen, the planned hour value is displayed 1.50 or 1.00

Am using the below condition in plan view screen:

txtPlannedHours.Text = PlannedTime.ToString().Remove(4);


since i have passed a value as 4 in remove string method, its appending a value as zero when the planned hour length is only 3 .

so how can i resolve this issue? so that it should display correct value as what ever was entered while creating in C#.


So when 12.5 was entered while creating, even in view it should be displayed as 12.
and when 1 or 1.4 was entered while creating even in that case it should just display as 1 or 1.4 instead of 1.00 or 1.40
