你的问题细节太少，但作为一个建议，我会尝试放一些代码，也许它会给你一些提示。

// In case if you're dealing with WinForms
// For WPF solution could have similar approach

public class DataGridForm : Form
{
    private DataGrid _grid;

    public DataGridForm()
    {
        InitializeComponent();// <-- here _grid is instantiated      
    }

    public void LoadData(object data)
    {
        // load data into grid
        // I don't know, could be smt like
        DataGridCell cell = _grid.Cells[0,0];
        cell.Value = data; 
    }
}

public class FormWithComboBox : Form
{
    private ComboBox _comboBox;

    public DataGridForm DataGridForm { get; set; }// value is set by some externat user

    public FormWithComboBox()
    {
        InitializeComponent();// <-- here _grid is instantiated      
        // including handler for OnSelectedItemChanged event
    }

    private void _comboBox_OnSelectedItemChanged(object sender, EventArgs e)
    {
        DataGridForm.LoadData(_comboBox.SelectedItem);
    }
}

如何使用C＃.net将一个表单中的组合框中的数据传递到Windows应用程序中另一种形式的gridview
