[英]How to get ResourcesTree node from schedulerstorage resource datasource in Devexpress Winforms
[英]In devexpress winforms, how can I import data into spreadsheet from a datasource?
下面是我的代码。 基本上,我只想从数据表及其原始列和行将数据输出到电子表格中。
public Spreadsheet()
{
InitializeComponent();
Worksheet worksheet = spreadsheetControl1.Document.Worksheets[0];
string connectionString = null;
SqlConnection conn;
connectionString = "Server=localhost\\SQLEXPRESS;Integrated security=SSPI;database=jms";
SqlDataAdapter sda = new SqlDataAdapter("Select * from students", connectionString);
conn = new SqlConnection(connectionString);
DataTable dt5 = new DataTable("Students");
worksheet.Import(dt5, true, 1, 1);
}
我知道这很旧,但是您尚未用任何数据填充DataTable
。
您的代码应如下所示:
DataTable dt5 = new DataTable("Students");
//this actually executes the SQL and populates the DataTable
sda.Fill(dt5);
worksheet.Import(dt5, true, 1, 1);
