Hai
Purpose: To make custom column to enter only decimals (inlcuding period once).
I use Code below to read current cell value from Datagrid in PreviewKeyDown.
and I am getting the value also.The content received is like this
"System.Windows.Controls.DataGridCell:" then cell text. But I want only the Content of cell.
Please tell me how to get this and I want this in PreviewKeyDown event or OnPreviewTextInput.
var cellInfo = Dgv.SelectedCells[0];
var cellContent = GetDataGridCell(cellInfo);
string xx = Convert.ToString(cellContent);
MessageBox.Show(Convert.ToString(xx));
public DataGridCell GetDataGridCell(DataGridCellInfo cellInfo)
{
var cellContent = cellInfo.Column.GetCellContent(cellInfo.Item);
if (cellContent != null)
return (DataGridCell)cellContent.Parent;
return null;
}
void OnPreviewTextInput(object sender, System.Windows.Input.TextCompositionEventArgs e)
{
e.Handled = new Regex("[^0-9.]").IsMatch(e.Text);
}
I want to check weather period exist more than once. Or is there any alternate.
Thanks
programmer
