Winform中用comboBox来选择显示Dataset中表格数据

2024年4月28日发(作者：)

for (int i = 0; i < 1000; i++)

{

("Item 1" + ng());

}

ate();

}

//初始化数据可以从数据库中取

public DataSet initdata()

{

ds = CreateHotelPriceDataSet();

for (int i = 0; i <= 5;i++ )

{

DataRow dr = ["test"].NewRow();

dr["CityCode"] = "CityCode_" + ng();

dr["HotelCode"] = "HotelCode_" + ng();

dr["testHotelCode"] = "testHotelCode_" + ng();

["test"].(dr);

DataRow dr2 = ["testtest88"].NewRow();

dr2["CityCode"] = "2CityCode_" + ng();

dr2["HotelCode"] = "2HotelCode_" + ng();

dr2["testHotelCode"] = "2testHotelCode_" + ng();

dr2["test"] = "2test_" + ng();

["testtest88"].(dr2);

}

return ds;

}

public static DataSet CreateHotelPriceDataSet()

{

DataSet ds = new DataSet();

DataTable dtHotelDetails = new DataTable("test");

("CityCode", typeof(String));

("HotelCode", typeof(String));

("testHotelCode", typeof(String));

(dtHotelDetails);

DataTable RoomsInfo = new DataTable("testtest88");

("CityCode", typeof(String));

("HotelCode", typeof(String));

("testHotelCode", typeof(String));

("test", typeof(String));

// (dtHotelDetails);

(RoomsInfo);

return ds;

}

private void cbtable_SelectedValueChanged(object sender, EventArgs e)

{

//string select = ng();

//string select2 = ng();

// string select = ng();

string select2 = ;

if (select2 != "naryEntry")

{

urce = [ng()].DefaultView; //["table1"].DefaultView;//['"'+select2+'"'].DefaultView;

}

}

private void button1_Click(object sender, EventArgs e)

{

int selectedIndex = edIndex;

Object selectedItem = edItem;

// Object selectvale = edValue;

("Selected Item Text: " + ng() + "n" +

"Index: " + ng());

}

//填充选择表

private void button2_Click(object sender, EventArgs e)

{

();

ds = null;

ds = initdata();

pdate();

for (int i = 0; i < ; i++)

{

([i].TableName);

}

ate();

edIndex = 0;

}

}

}

总体来说实现了想要的效果。
