範例

下列程式碼範例示範設定各種 ToolStripTextBox 通用屬性設定的語法,包括 MaxLength 屬性 。

// This code example demonstrates the syntax for setting
// various ToolStripTextBox properties.
// 
toolStripTextBox1.AcceptsReturn = true;
toolStripTextBox1.AcceptsTab = true;
toolStripTextBox1.AutoCompleteCustomSource.AddRange(new string[] {
"This is line one.",
"Second line.",
"Another line."});
toolStripTextBox1.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend;
toolStripTextBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource;
toolStripTextBox1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle;
toolStripTextBox1.CharacterCasing = System.Windows.Forms.CharacterCasing.Upper;
toolStripTextBox1.HideSelection = false;
toolStripTextBox1.MaxLength = 32000;
toolStripTextBox1.Name = "toolStripTextBox1";
toolStripTextBox1.ShortcutsEnabled = false;
toolStripTextBox1.Size = new System.Drawing.Size(100, 25);
toolStripTextBox1.Text = "STRING1\r\nSTRING2\r\nSTRING3\r\nSTRING4";
toolStripTextBox1.TextBoxTextAlign = System.Windows.Forms.HorizontalAlignment.Center;
' This code example demonstrates the syntax for setting

toolStripTextBox1.AcceptsReturn = True
toolStripTextBox1.AcceptsTab = True
toolStripTextBox1.AutoCompleteCustomSource.AddRange(New String() {"This is line one.", "Second line.", "Another line."})
toolStripTextBox1.AutoCompleteMode = System.Windows.Forms.AutoCompleteMode.SuggestAppend
toolStripTextBox1.AutoCompleteSource = System.Windows.Forms.AutoCompleteSource.CustomSource
toolStripTextBox1.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle
toolStripTextBox1.CharacterCasing = System.Windows.Forms.CharacterCasing.Upper
toolStripTextBox1.HideSelection = False
toolStripTextBox1.MaxLength = 32000
toolStripTextBox1.Name = "toolStripTextBox1"
toolStripTextBox1.ShortcutsEnabled = False
toolStripTextBox1.Size = New System.Drawing.Size(100, 25)
toolStripTextBox1.Text = "STRING1" + ControlChars.Cr + ControlChars.Lf + "STRING2" + ControlChars.Cr + ControlChars.Lf + "STRING3" + ControlChars.Cr + ControlChars.Lf + "STRING4"
toolStripTextBox1.TextBoxTextAlign = System.Windows.Forms.HorizontalAlignment.Center

備註

您可以使用此屬性來限制控制項中輸入的文字長度,例如郵遞區號和電話號碼,或限制在資料庫中輸入資料時輸入的文字長度。 您可以將控制項中輸入的文字限制為資料庫中對應欄位的最大長度。
