ado.net, data grid view updating

[clyde11]

Hello all,
I'm reading a tutorial about updating an sql table
using ado.net capabilities, in this example,
using a data grid to get input values and update the
needed row in the table, now, the problem is that
i don't really understand what is the content
of the "UpdateView()" function, i've tried several things but don't really achieve the thing updateView() need’s to do (just updating the view, after the :
"grid.EditItemIndex = e.Item.ItemIndex;")

if anyone can helps..
Best,
P.

public void EditCommand(Object sender,
DataGridCommandEventArgs e)
{
// Set the current item to edit mode
grid.EditItemIndex = e.Item.ItemIndex;

// Refresh the grid
UpdateView();
}

public void UpdateCommand(Object sender,
DataGridCommandEventArgs e)
{
// TODO: Retrieve new text and update the data source

// Reset the edit mode for the current item
grid.EditItemIndex = -1;

// Refresh the grid
UpdateView();
}

public void CancelCommand(Object sender,
DataGridCommandEventArgs e)
{
// Reset the edit mode for the current item
grid.EditItemIndex = -1;

// Refresh the grid
UpdateView();
}

UpdateView() is a function that rebinds the DataGrid. You do this after every time you excute you DataGridCommand(Update, Cancel, Delete) code.

I'm assuming you got this code from somewhere because you mentiobned a tutorial - consult that code. There should eb a function called UpdateView
