我正在使用存储过程添加客户。插入后我以某种方式设法选择了新添加的客户,但我无法专注于列表框中的记录..
我尝试了一切,例如:
lbxCustomers.ScrollIntoView(this.lbxCustomers.SelectedIndex);
并使用物品和东西进行了许多修改,但没有任何效果。它仍然没有将视图滚动到所选项目..有什么想法吗?
这是WPF。
我的初始化看起来像这样:
private void init()
{
SqlConnection connection = null;
SqlDataReader reader = null;
try
{
connection = new SqlConnection(this.strConnection);
connection.Open();
SqlCommand command = new SqlCommand("SELECT CustomerID, CompanyName, ContactName FROM Customers", connection);
SqlDataAdapter sda = new SqlDataAdapter(command);
reader = command.ExecuteReader();
ListItem listItem;
while (reader.Read())
{
listItem = new ListItem(reader.GetValue(0).ToString(), reader.GetValue(1).ToString(), reader.GetValue(2).ToString());
this.lbxCustomers.Items.Add(listItem);
}
}
catch (Exception e)
{
MessageBox.Show(e.Message, "Error", MessageBoxButton.OKCancel, MessageBoxImage.Exclamation);
}
finally
{
connection.Close();
reader.Close();
}
}
init2 是相同的,除了以下行:
SqlCommand command = new SqlCommand("SELECT CustomerID, CompanyName, ContactName FROM Customers WHERE CompanyName = '" + correctID + "'", connection);
它指的是 ListItem,它看起来像这样:
class ListItem
{
private string customerID, companyName, contactName;
public ListItem(string customerID, string companyName, string contactName)
{
this.customerID = customerID.Replace("'", "''");
this.companyName = companyName.Replace("'", "''");
this.contactName = contactName.Replace("'", "''");
}
public override string ToString()
{
return this.companyName + " (" + this.contactName + ")";
}
public string CustomerID
{
get { return this.customerID; }
}
}
