Getting Variable Value from One form to another

[everard]

I have a program with multiple form in C#. I used a DataGridView to display a list of Students from my database. Whenever the user clicks on the datagrid, it automatically saves the name of the selected student on a string variable.

My question now is, how can I get the value of that variable from Form1 to Form2?

I almost never use C# but this might help.
Try in form1:
form2.Variable

That might work (it does in Vb and C# is C++ combined with vb so I guess It would work..)

I tried that already but it doesn't work.

Everything in .Net is an object and derives from System.Object. So, even a form is an object.

//Create object of Form2
Form2 frm = new Form2();

//Now access that variable and set it's value
frm.Variable = set_value

One note is the in Form2, the variable "Variable" must be set to public or else an error will be generated.

//Create object of Form2
Form2 frm=new Form2();

//Assign the value to Form2 Variable
frm.variablename=value

Another question, how can I get a specific value from a data column? For example, I have a row for student's last name, first name, middle name, course, and year level. Then when the user clicks on a single student record, the last name of the selected student will automatically assigned to variable "StudLastName".

Sorry, my question was not detailed. What I'm trying to ask is how can I get a specific value from a datagridview. Getting a specific data from a student (ex. LastName).

[JenniferBabe]

ok you want to click on a row and retrive the student last name correct? That is a very simple method for a data table structure, I cant' rememebr it right now but it's simple, you just got to pass the name of the column to pull out what you want. From what I see, its mostly string manipulation that might solve your problem.

If you can't find the method, please reply, if so I will find some time to look up the method for you.

I guess this is what you're looking for
DataGridView[0, DataGridView.CurrentCell.RowIndex].Value;
0 is the colomnumber
