Not exactly sure what you mean by this, but, it sounds like perhaps you should use a TemplateColumn and adjust the button controls as required.

Handle the RowDataBound or RowCreated event and update the button text appropriately.

i couldnt find both events that u suggested...i have UserAddedRows and RowsAdded..i tried both

private void datagridview1_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
        {
            datagridview1.CurrentRow.Cells[6].Value = "Insert";
        }

i cant catch Text Property here..that is why i used Value property but it gives error like "Object reference not set to an instance of an object."
so what else i can try ?

This[^] may help.

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

You cannot change the Location. It´s readonly. You can use the Left or Top property (I never know what X/Y is ...)

I cannot remember: What did I before google?

Shouldn't this be You.Location.X += 1;? BTW, you haven't actually shown what your error is, you've just shown where it is.

I'm not a stalker, I just know things. Oh by the way, you're out of milk.

You can't change the values of a Point: they are read only.
Create a new point instead:

private void Form2_keydown(object sender, KeyEventArgs e)
        {
          if (e.KeyCode == Keys.Up)
            {
                You.Location = new Point(You.Location.X + 1, You.Location.Y);
            }
        }

The online help for the Location property describes the behaviour and how to resolve your problem.
Control.Location Property "Because the Point class is a value type (Structure in Visual Basic, struct in Visual C#), it is returned by value, meaning accessing the property returns a copy of the upper-left point of the control. So, adjusting the X or Y properties of the Point returned from this property will not affect the Left, Right, Top, or Bottom property values of the control. To adjust these properties set each property value individually, or set the Location property with a new Point."

You.Location.X = new Point(You.Location.X +1, You.Location.Y);

Architecture is extensible, code is minimal.
