How to prevent form from auto loading when running the application?

Question

i have a data grid view in a form,its data source code is in form load event which depends on variables in the main form, but when i enter the variables in the main form it goes wrong because the form was loaded when i run the application before i enter the variables
so i need the form to load only when i use the code below
i hope i expressed it clearly

Answer 1

Did you put this code in main form's form load event code? if you did then that's why formtable is loaded.

If the formtable is already loaded simply set the form to foreground and set the grid filter with your input in main form.

Please clarify what you mean by "it goes wrong"?

Sorry if I misunderstood you.

Answer 2

@Aziz, let's begin with fixing that code in formtable_load.
on line 14:
Replace case(universal.x) with switch(universal.x)

Then we'll talk again, good luck.

Answer 3

@Aziz, add another button and write the same code with button1_click, but change universal.x=0. Test if that works assigning dt1 for the grid. I'll be waiting.

Answer 4

@Aziz let's verify the value of universal.x in formtable by adding a label control, and before switch(universal.x) add label1.Text=universal.x; I'm curious why this is happening.

Answer 5

@Aziz, great, can I see the changes you made

Answer 6

i found the mistake
i swapped line 14 with line 15,16 in button1 code
thank you for your patience

Answer 7

it's my bad because i don't know where to start.
i have 2 forms: main form and table form

main form has button1 which load formtable

universal is a class and x is public static with default value 0

formtable_load code is
https://code.sololearn.com/ci83DNE8VyxO/?ref=app

when i click on button1 i get dt1 instead of dt2
but when i click on it for second time i get dt1
I'm not sure what's wrong

Answer 8

sorry about that, of course I didn't write that in the actual project :)

Answer 9

i have already button2 with x=0, it works perfectly
