創建自定義的驗證供應商的DevExpress

Question

我使用的DevExpress 13.1和我想創建一個自定義的驗證提供了一個文本框

我嘗試用這個代碼

DevExpress.XtraEditors.DXErrorProvider.ConditionValidationRule containsValidationRule = new DevExpress.XtraEditors.DXErrorProvider.ConditionValidationRule(); 
containsValidationRule.ConditionOperator = DevExpress.XtraEditors.DXErrorProvider.ConditionOperator.GreaterOrEqual; 
containsValidationRule.Value1 = '0'; 
containsValidationRule.ErrorText = "Veuillez saisir un valeur supérieur a zéro"; 
containsValidationRule.ErrorType = ErrorType.Warning; 

CompareAgainstControlValidationRule compValidationRule = new CompareAgainstControlValidationRule(); 
compValidationRule.Control = txtStockMax; 
compValidationRule.CompareControlOperator = CompareControlOperator.LessOrEqual; 
compValidationRule.ErrorText = "Veuillez saisir un valeur inférieur au stock max"; 
compValidationRule.CaseSensitive = true; 

dxValidationProvider1.SetValidationRule(txtStockMin, containsValidationRule); 
dxValidationProvider1.SetValidationRule(txtStockMin, compValidationRule); 

我要找的是該txtStockMin是greaterOrEqual比0和txtStockMin是lessOrEqual到txtStockMax

請檢查DXValidationProvider幫助話題。本主題還包含一個清晰的代碼示例，介紹如何創建任何自定義驗證規則。
