Control.EnsureChildControls Method
Assembly: System.Web (in system.web.dll)
This method first checks the current value of the ChildControlsCreated property. If this value is false, the CreateChildControls method is called.
ASP.NET calls it this method when it needs to make sure that child controls have been created. In most cases, custom server control developers do not need to override this method. If you do override this method, use it in a similar fashion as its default behavior.
The following example uses the EnsureChildControls method to ensure that the current server control has child controls. It then gets or sets a Text property for a child TextBox Web control in the current server control's ControlCollection object.
// Ensure the current control has children, // then get or set the Text property. public int Value { get { this.EnsureChildControls(); return Int32.Parse(((TextBox)Controls[1]).Text); } set { this.EnsureChildControls(); ((TextBox)Controls[1]).Text = value.ToString(); } }
// Ensure the current control has children,
// then get or set the Text property.
/** @property
*/
public int get_Value()
{
this.EnsureChildControls();
return Int32.Parse(((TextBox)(get_Controls().get_Item(1))).get_Text());
} //get_Value
/** @property
*/
public void set_Value(int value)
{
this.EnsureChildControls();
((TextBox)get_Controls().get_Item(1)).set_Text(((Int32)value).ToString());
} //set_Value
// Ensure the current control has children, // then get or set the Text property. public function get Value() : int { this.EnsureChildControls(); return Int32.Parse(TextBox(Controls[1]).Text); } public function set Value(value : int) { this.EnsureChildControls(); TextBox(Controls[1]).Text = value.ToString(); }
