I am working on a matrix problem in C# windows form application and i have gotten alot of the code to work but cant get

I am working on a matrix problem in C# windows form application and i have gotten alot of the code to work but cant get the calculate button to work. When i get the matrix to be generated and click multiply or add or subtract it automaticly calculates without me pressing the calculate button. Another thing that isnt working is the rows and cols text boxes should have a default value of 3 when the program is ran. Also i cant seem to figure out how to Make the matrix and Identiy. When i clik the Make B identity it should convert the matrix to an identity but cant seem to figure it out. could you please fix the code so i could understand what changes i should make in order for it to work.

The Select Operation GroupBox has 3 RadioButton objects to multiply matrices, add matrices and subtract matrices, respectively. The Multiply RadioButton should be checked when the form loads (Hint: double-click on the form-What event is created?). Make sure that only one RadioButton can be selected at a time. The calculate Button should perform the operation selected in the Select Operation GroupBox. Make sure that no operation can crash your application and that all operations can only execute correctly. You can use a validation approach or handle the exceptions. In any case, provide a clear message to the user what went wrong and how to correct the problem. Things to consider: 1. The A and B matrix are not nu 2. For multiplication, the rows of A match the columns of B and the columns of A match the rows of B 3. For addition and subtraction the A and B matrices should have the same dimensions. When calculate is clicked, the C matrix should be created with the proper dimensions to contain the result of the operation given the sizes of A and B. After selecting Multiply and clicking Calculate, the form should have the result in the Matrix C TextBox as shown below. Matrix ops A Marne B 3 Make Malik A Make Matt Make B identity Select Operaton Mutoly O Add O subtract
