C# Step by Step How to dynamically get values from textboxes into gridview

First Step Open Visual studio 

Click on New Project

Now Menu visible Select option Visual C# just like in Picture below

now  select windows form from visual C# windows and name project and save it

now project will be loaded and open the project to design and code

now their is form visible you can now start working

now you see label in toolbox where it can be dragged to create identification of something on interface to use it

now we have dragged

now to change the name of label1 to ID so we write click of mouse and go to its properties which will be visible on write side to change the text name just like below

Another label drag and dropped and change the text name to Name

Now we need textBoxes to get values from user

To identify user to use it we have to change its accessability name value to use in code by going to its properties

Now its accessable for id values now applying same above procedure we have to show textbox for name in change accessibility name is txtName

now to save the data we have to use button on interace where user click and these values in boxes will be stored by drag button from toolbox and drop on form just like that below and change textname from button to Save by using properties

 changing accessibility name of the button to accessable in code

Now after that we need some visible excel like sheet view to visible all the records on button click to user in less time so for show data we use gridview and then drag from toolbox and drop it on form

just like below

now we do code by double click on interface where save button is displaying click on it you will se code view where you can do code

after coding with no error debug and result will be displayed you give input and result dropped and showed in gridview just like that

make sure your project name is same at that line else you will get error to run code

write code as below with different textboxes are used on interface like txtID and txtName dont confuse below is mine written code with different names so dont write as exact just go to your button , textbox property and copy accessibility name use them in code you will avoid errors
