Capturing Mouse Wheel event in C#

Microsoft chose not to display the MouseWheel event in the Event box. However, it is easy to hook it through the editor.

In the constructor of the Form / custom control, type - "MouseWheel+=", and press TAB twice. Once for completing the statement, and again to insert the handler in the class.

to catch the wheel rotation, if the value of e.Delta >0 then it scrolls up and if the value of e.Delta <0 then it scrolls down:

if (e.Delta < 0)
    x--;
else
    x++;

Create Duplicate Table in MySQL

MySQL provides many methods to create duplicate table with its data or without its data. The following is a simple example to create a duplicate table along-with data of the original table:

CREATE TABLE new_table_name SELECT * FROM old_table_name; 

An important point to note is that this query will not create column attributes and indexes as defined in the original table.

If you also want to have such attributes, this can be done with another easy way. Below queries will create a copy of the original table with all its constraints and attributes and also insert entire data from the original table to the new on:

CREATE TABLE new_table_name LIKE old_table_name;

INSERT INTO new_table_name SELECT * FROM old_table_name;

Teleric Radcontrol Combobox on SelectedIndexChanged

The SelectedIndexChanged event occurs when the user selects a new item in the drop-down list.

The SelectedIndexChanged event does not fire unless the AutoPostBack property is True.

The SelectedIndexChanged event handler receives two arguments:

1. The RadComboBox that is loading items. This argument is of type object, but can be cast to the RadComboBox type.
2. An EventArgs object. This object has the following properties for identifying what has changed:
   • Text is the text of the item that was just selected.
   • Value is the value of the item that was just selected.
   • OldText is the text of the item that was previously selected
   • OldValue is the value of the item that was previously selected

Use the SelectedIndexChanged event handler to respond in server-side code when the user changes the current selection:

  

ASPX code:

<telerik:radcombobox 
  id="RadComboBox1" 
    runat="server" 
    autopostback="True" 
    onselectedindexchanged="RadComboBox1_SelectedIndexChanged">
</telerik:radcombobox>

C# code behind:

private void RadComboBox1_SelectedIndexChanged(object o, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
{
    Label1.Text = "You selected " + e.Text + " item";
}
