调用DoValidate()始终返回true

解决方案

txtCarNo.IsModified = true;
result = result & txtCarNo.DoValidate();

 

 

LayoutControl设置LayoutControlItem的MaxSize和MinSize。

 

对于设置的最大Size和最小Size，能够设置simplebutton的AutoWidthInLayoutControl属性为true，并设置 当前simplebutton的layoutitem的 SizeConstraintsType属性为SupportHorzAlignment，便可使最大Size和最小Size起做用！

GridView验证行并取消不经过时弹窗  去掉验证行失败时弹出的确认框

        void gv_CardTime_ValidateRow(object sender, DevExpress.XtraGrid.Views.Base.ValidateRowEventArgs e)
        {
            bool V = true;
            if (String.IsNullOrEmpty(gv_CardTime.GetFocusedRowCellDisplayText("CardTime")))
            {
                gv_CardTime.SetColumnError(gridColumn1, "时间不能为空!");
                //e.ErrorText = "时间不能为空！";
                V = false;
            }
            e.Valid = V;

        }



        void gv_CardTime_InvalidRowException(object sender, DevExpress.XtraGrid.Views.Base.InvalidRowExceptionEventArgs e)
        {
            //去掉验证行失败时弹出的确认框
            e.ExceptionMode = DevExpress.XtraEditors.Controls.ExceptionMode.NoAction;
        }

慎于行,敏于思！GGGGGG
