Next, you need to override the InitializeEditingControl() method to configure the editing control when the cell switches into editing mode. This is the point at which you need to copy the value from the cell into the editing control. ... public override void InitializeEditingControl(int rowIndex, object initialFormattedValue, DataGridViewCellStyle dataGridViewCellStyle) { base.InitializeEditingControl(rowIndex, initialFormattedValue, dataGridViewCellStyle); CalendarEditingControl ctl = (CalendarEditingControl)DataGridView.EditingControl; ctl.Value = (DateTime)this.Value; } ... And last of all, you can override the DefaultNewRowValue property to set the default content that should appear in this column when a new row is inserted. ... public override object DefaultNewRowValue { get { // Use the current date and time as the default value. return DateTime.Now; } } } Now the only remaining task to create the example shown in Figure 15-16 is to build the custom CalendarEditingControl. This step is quite easy, although there s a fair bit of boilerplate code to write. The basic technique is to derive a new class from the .NET control that you want to use. For example, in this case you need the editing features of the DateTimePicker, so it makes sense to derive from the DateTimePicker control class. However, there s another ingredient every control needs to work as an editing control for the DataGridView it must implement IDataGridViewEditingControl. Here s the class declaration you need: public class CalendarEditingControl : DateTimePicker, IDataGridViewEditingControl { ... } The rest of the work is to implement the IDataGridViewEditingControl members. Most of these are quite straightforward. For example, you need properties that expose the linked DataGridView, the current row index: how to create a thumbnail image of a pdf in c#: PDF Thumbnail Generator download | SourceForge.net generate pdf thumbnail c# Generate Thumbnail Images from PDF Documents - Aspose.PDF for ...

This is a 500 pages concise technical eBook available in PDF , ePub (iPad), and Mobi ... private DataGridView dataGridView; public DataGridView EditingControlDataGridView { get { return dataGridView; } set { dataGridView = value; } } private int rowIndex; public int EditingControlRowIndex { get { return rowIndex; } set { rowIndex = value; } } Notice you don t need to supply any real code, other than a private variable to track each of these details. The DataGridView takes care of setting these properties when it creates an editing control. Along with these basics are some more important details. For example, whenever the value changes in your editing control, you need to call the DataGridView.NotifyCurrentCellDirty() method to notify the DataGridView (which will then display the pencil icon next to that cell). In the case of the DateTimePicker, the easiest way to implement this step is to override the OnValueChanged() method: // This is the only member in CalendarEditingControl that's not implemented // to satisfy the IDataGridViewEditingControl interface. protected override void OnValueChanged(EventArgs eventargs) { // Notify the DataGridView that the contents of the cell // have changed. valueChanged = true; this.EditingControlDataGridView.NotifyCurrentCellDirty(true); base.OnValueChanged(eventargs); } private bool valueChanged = false; public bool EditingControlValueChanged { get { return valueChanged; } set { valueChanged = value; } } Notice that you also need to implement the EditingControlValueChanged property to track whether the control value has changed. Another property you need to implement is EditingControlFormattedValue. This property allows your control to receive a formatted string from the cell, which it must convert into the appropriate DateTime value and display. generate pdf thumbnail c# Generate a pdf thumbnail (open source/free) - Stack Overflow

The last business tier addition to make is a method for updating orders. Previously you ve achieved this using the OrderAccess.Update method, which used an OrderInfo struct parameter to specify the data to update. Now you have a more active representation of order data, namely public object EditingControlFormattedValue { get { return this.Value.ToShortDateString(); } set { string newValue = value as string; if (newValue != null) this.Value = DateTime.Parse(newValue); } } public object GetEditingControlFormattedValue( DataGridViewDataErrorContexts context) { return EditingControlFormattedValue; } Two more interesting methods are ApplyCellStyleToEditingControl() and EditingControlWantsInputKey(). In ApplyCellStyleToEditingControl(), you configure the control to match the style properties of the DataGridViewCell. In EditingControlWantsInputKey(), you define what keystrokes your control should handle. public void ApplyCellStyleToEditingControl( DataGridViewCellStyle dataGridViewCellStyle) { this.Font = dataGridViewCellStyle.Font; this.CalendarForeColor = dataGridViewCellStyle.ForeColor; this.CalendarMonthBackground = dataGridViewCellStyle.BackColor; } public bool EditingControlWantsInputKey( Keys key, bool dataGridViewWantsInputKey) { // Let the DateTimePicker handle the keys listed. switch (key & Keys.KeyCode) { case Keys.Left: case Keys.Up: case Keys.Down: case Keys.Right: case Keys.Home: case Keys.End: case Keys.PageDown: case Keys.PageUp: return true; default: return false; } } The Odejava sphere combines GeomSphere and Body objects. The GeomSphere is for detecting collisions with other spheres and the box. The Body object stores the mass, position, and the linear and angular velocities. create pdf thumbnail image c# C# Create PDF Thumbnail SDK: View, preview PDF thumbnail ...
