示例1: AllowDelete
public void AllowDelete()
{
DataTable dt = DataProvider.CreateParentDataTable();
DataView dv = new DataView(dt);
// AllowDelete - default value
Assert.Equal(true, dv.AllowDelete);
// AllowDelete - true
dv.AllowDelete = true;
Assert.Equal(true, dv.AllowDelete);
// AllowDelete - false
dv.AllowDelete = false;
Assert.Equal(false, dv.AllowDelete);
dv.AllowDelete = false;
// AllowDelete false- Exception
Assert.Throws<DataException>(() =>
{
dv.Delete(0);
});
dv.AllowDelete = true;
int RowsCount = dv.Count;
// AllowDelete true- Exception
dv.Delete(0);
Assert.Equal(RowsCount - 1, dv.Count);
}示例2: TestDeleteAndCount
public void TestDeleteAndCount()
{
DataSet dataset = new DataSet("new");

dataView.AllowDelete = true;
// Deleting the first row
dataView.Delete(0);
Assert.Equal(2, dataView.Count);
}示例3: Delete
public void Delete()
{
//create the source datatable
DataTable dt = DataProvider.CreateChildDataTable();
//create the dataview for the table
DataView dv = new DataView(dt);
int CountView = dv.Count;
int CountTable = dt.Rows.Count;
DataRowView drv = dv[0];
// Delete - DataView Row Count
dv.Delete(0);
Assert.Equal(dv.Count, CountView - 1);
// Delete - Table Row Count
Assert.Equal(dt.Rows.Count, CountTable);
// Delete - check table
Assert.Equal(dt, drv.Row.Table);
}示例4: TestDeleteClosed
public void TestDeleteClosed()
{
Assert.Throws<IndexOutOfRangeException>(() =>
{
DataView TestView = new DataView(_dataTable);

dataset.AcceptChanges();
DataView dataView = new DataView(dataset.Tables[0]);
// 'new' table in this sample contains 6 records
dataView.AllowEdit = true;
