Then How to get RowIndex of a wpf datagrid when i Checked or Unchecked CheckBox of WPF DataGrid Column…

Answer 1

Actually you don’t need row index. What you really need is changing your bound item. According to your previous question, you are trying to change properties of items, assigned to grid. You don’t have to do that manually. If you have class

public class UserForm
{
    public int FormId { get; set; }
    public string FormName { get; set; }
    public bool Visibility { get; set; }
}

And you assign list of forms to DataGrid:

<DataGrid ItemsSource="{Binding UserForms}" />

or from code

dataGrid.AutoGenerateColumns = true;
dataGrid.ItemsSource = UserForms;    

Then properties of bound UserForm object will be updated when you check/uncheck checkboxes in Visibility column of grid.
