Gets or sets the starting point of text selected in theToolStripTextBox.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
If no text is selected in the control, this property indicates the insertion point for new text. If you set this property to a location beyond the length of the text in the control, the selection start position will be placed after the last character. When text is selected in the text box control, changing this property might decrease the value of the SelectionLength property. If the remaining text in the control after the position indicated by the property is less than the value of the SelectionLength property, the value of the SelectionLength property is automatically decreased. The value of the property never causes an increase in the SelectionLength property.
You can programmatically move the caret within the text box by setting the to the position within the text box where you want the caret to move to and set the SelectionLength property to a value of zero (0). The text box must have focus in order for the caret to be moved.
