示例1: Form_AccountList
public Form_AccountList()
{
InitializeComponent();
dataSet1 = arxDs.ds;
accountsBindingSource.DataSource = arxDs.ds;
dataGridView1.DataSource = accountsBindingSource;
using (var remainingColumn = new DataGridViewTextBoxColumn { Width = 100, HeaderText = "Текущее состояние", ReadOnly = true })
{
dataGridView1.Columns.Add(remainingColumn);
}
var view1 = new DataView(arxDs.ds.Tables["Accounts"], "", "",
DataViewRowState.CurrentRows);
if (!view1.Cast<DataRowView>()
.Any(rv => rv.Row.Field<string>("Account") == "Основной"))
{
DataRowView newRow = view1.AddNew();
newRow["Account"] = "Основной";
newRow["StartSum"] = 0;
newRow.EndEdit();
}
}示例2: fillComboBoxes
private void fillComboBoxes()
{
var view1 = new DataView(arxDs.ds.Tables["Accounts"], "", "",
DataViewRowState.CurrentRows);
var view2 = new DataView(arxDs.ds.Tables["Accounts"], "", "",
DataViewRowState.CurrentRows);
if (!view1.Cast<DataRowView>()
.Any(rv => rv.Row.Field<string>("Account") == "Основной"))
{
DataRowView newRow = view1.AddNew();
newRow["Account"] = "Основной";
newRow["StartSum"] = 0;
newRow.EndEdit();
}
comboBox1.DataSource = view1;
comboBox1.DisplayMember = "Account";
comboBox2.DataSource = view2;
comboBox2.DisplayMember = "Account";
}示例3: GetKeys
public IEnumerable<KeyValuePair<string, CryptoKey>> GetKeys(string bucket) {
// properly escape the URL to prevent injection attacks.
string value = bucket.Replace("'", "''");
string filter = string.Format(
CultureInfo.InvariantCulture,
"{0} = '{1}'",
dataSet.CryptoKey.BucketColumn.ColumnName,
value);
string sort = dataSet.CryptoKey.ExpiresUtcColumn.ColumnName + " DESC";
DataView view = new DataView(dataSet.CryptoKey, filter, sort, DataViewRowState.CurrentRows);
if (view.Count == 0) {
yield break;
}
foreach (CustomStoreDataSet.CryptoKeyRow row in view.Cast<DataRowView>().Select(rv => rv.Row)) {
yield return new KeyValuePair<string, CryptoKey>(row.Handle, new CryptoKey(row.Secret, row.ExpiresUtc));
}
}示例4: GetIndexNames
private static IEnumerable<string> GetIndexNames(DataView indexes)
{
var list = new List<string>();
foreach (var indexName in indexes.Cast<DataRowView>().Select(row => row["INDEX_NAME"].ToString()).Where(indexName => !list.Contains(indexName)))
{
list.Add(indexName);
}
return list.OrderBy(n => n);
}示例5: SaveRemarks
static public void SaveRemarks(string ownerGUIDFieldName, string ownerGUID, string userMessagePrefix, DataView v)
{
if (v == null) return;
string savefilter = v.RowFilter;
v.RowFilter = "";
// ReSharper disable InconsistentNaming
using (var Remark_u = new iTRAACProc("Remark_u"))
// ReSharper restore InconsistentNaming
foreach (var remark in v.Cast<DataRowView>().Where(remark => remark.IsDirty()))
{
Remark_u.AssignValues(remark);
if (!Remark_u.ExecuteNonQuery(userMessagePrefix + " Save Remark: ")) continue;
remark["RowGUID"] = Remark_u["@RowGUID"]; //for inserts
remark.AcceptChanges();
}
v.RowFilter = savefilter;
