使用控件 DxValidationProvider
/*用代码设置规则*/
/// <summary> /// 设置控件组对象必填 /// </summary> /// <param name="validationProvider">DXValidationProvider类型对象</param> /// <param name="param">一组BaseEdit对象</param> public static void SetRequired(DXValidationProvider validationProvider, params BaseEdit[] param) { //实例化一个必填规则，错误提示为：该字段不能为空 ConditionValidationRule required = new ConditionValidationRule("RequiredRule", ConditionOperator.IsNotBlank) { ErrorText = $"该字段不能为空" }; for (int i = 0; i < param.Length; i++) { //给控件对象设置规则 validationProvider.SetValidationRule(param[i], required); //设置文本显示位置 validationProvider.SetIconAlignment(param[i], ErrorIconAlignment.MiddleRight); } }
验证时使用
//false时未全部通过验证 bool valid= dxValidationProvider1.Validate();
实例：
二、设置输入限制（在TextDdit正则）
//常用正则 -?\d* 可负整数 (\d|[1-9]\d*)(\.\d+)? 正实数 -?(\d|[1-9]\d*)(\.\d+)? 实数 ([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(\.[a-zA-Z0-9_-]+)+ 邮箱 ([1-9]\d{6,7})|(0\d{2}-\d{8}(-\d{1,4})?)|(0\d{3}-\d{7,8}(-\d{1,4})?) 电话号码 1[3,4,5,7,8]\d{9} 手机号码 [0-9a-zA-Z]+ 账户信息,包含字母和数字 \d{6} 邮编 (\d+(\;?|\；?|\*?|\,?|\，?))+ 发票号及‘*’，‘；’，‘;’,‘，‘
以仅能输入数字为例："\d+"
textEdit1.Properties.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.RegEx; textEdit1.Properties.Mask.IgnoreMaskBlank = true; textEdit1.Properties.Mask.AutoComplete = DevExpress.XtraEditors.Mask.AutoCompleteType.None; textEdit1.Properties.Mask.EditMask = @"\d+"; //设置输入提示 textEdit1.Properties.NullValuePromptShowForEmptyValue = true; textEdit1.Properties.NullValuePrompt = "请输入数字"; textEdit1.ToolTip = "请输入数字"; //ButtonEdit同上 buttonEdit1.Properties.Mask.MaskType = DevExpress.XtraEditors.Mask.MaskType.RegEx; buttonEdit1.Properties.Mask.IgnoreMaskBlank = true; buttonEdit1.Properties.Mask.AutoComplete = DevExpress.XtraEditors.Mask.AutoCompleteType.None; buttonEdit1.Properties.Mask.EditMask = @"\d+"; //设置输入提示 buttonEdit1.Properties.NullValuePromptShowForEmptyValue = true; buttonEdit1.Properties.NullValuePrompt = "请输入数字"; buttonEdit1.ToolTip = "请输入数字"; //GridColumn gridColumn1.DisplayFormat.FormatType = FormatType.Custom; gridColumn.DisplayFormat.FormatString = @"\d+"; //添加输入提示 gridColumn1.ToolTip = "请输入数字";
