C#: adding a new row to datagrid with values from textboxes using bindingsource

I have a datagridview and textboxes all bound to a bindingsource. I also have buttons for actions Create and Update. The latter works as intended: the item in the selected row updates with values from the textboxes. Here's the whole code behind the Update button:
myBindingSource.EndEdit();
myTableAdapter.Update(myDataSet.myTable);
The Create button in current implementation adds an empty row and clears all the textboxes, so the only way to add actual values is using the Update button afterwards. Here's the whole code behind the Create button:
myBindingSource.CancelEdit();
myBindingSource.AddNew();
But I want the Create button to add a row with values already entered into the textboxes, and then clear them. I tried to only use this line:
myBindingSource.AddNew();
But if I don't cancel pending changes, 1) they'll be applied to the item currently selected in datagridview, 2) an empty row will be added to datagridview.
How can I change the Create button's behavior, so that it added rows with values from the textboxes without affecting currently selected row?

How to add new editable row on the first row of a Populated GridView OnClick

I am currently working on a website using ASP.Net and C# on Visual Studio 2012.
I have a GridView that displays data on Page_Load from my database and a button that should add new row AT THE FIRST ROW of my GridView .
Is there a way on doing this? I tried adding rows with textboxes dynamically but I can't retrieve the input data from it because it disappears on PostBacks.
Ideas so far:
Start populating the gridview from 2nd row to make the first row
clear and add control to it from the client side but I dont know how
to do it and if it is even possible.
Place the textboxes on the HeaderRow, then hide HeaderRow on Page_Load, then display the HeaderRow on button click. But the labels of the column will disappear because it will be replaced with TextBoxes.

how to add button click event in grid view in asp.net

1)
I had a GridView and I added a button in every row. I want to know how to select one row by clicking that button according to that row. And I should insert that record into an other table.
Eg:- I have two tables (Course and Wish List)
I bind the course details into the GridView and add a button as "ADD TO WISHLIST" at last column.
I want to add that record into the wishlist table clicking the button.
enter image description here
2)
My second need is: I have added an image in a database table as binary value successfully. But now I can't load this data. How can I do that?

How to add a new row into datagridview using grid only. i.e by showing textboxes and add button in WinForm

I want to add a new row to a datagridview such that when a user clicks on new button , a new is is generated with few textboxes and combo boxes and after filling up all the details he save the info by clicking on save button.
EDIT
I want to do it like it is seen in gridview(Template Fields) in asp.net
I am looking for same kind of functionality.

Since I'm not sure exactly how you want to achieve this.. I would have a hidden panel with your text boxes, ...etc, show the panel when the new button is clicked. After all information is entered into the fields, click the save button. Assuming that you will be inserting this information into a table, after the row is inserted, call the stored procedure to get the desired records from the table being displayed in the grid.

Assuming your _dataGridView.Columns collection is not null and contains a template of the rows you wish to add, it is as simple as something like this:
foreach(var item in _collection)
{
_dataGridView.Rows.Add(item.Foo, item.Bar);
}
In order for this to work, you will have had to design your Columns collection in the VisualStudio designer or programatically add DataGridViewTextBoxColumn objects to the Columns collection.
In the example above, I added two DataGridViewTextBoxColumn objects to the _dataGridView.Columns collection and then populated the datagrid from a List of my object that contained a 'Foo' and a 'Bar'.
EDIT
Have you checked out the DataGridView FAQ? The information about using the DataGridView in unbound mode may help you.
