备注：只适用于只读列

二.代码案例：

自定义单据提附加背景色方法：

///
/// 设置单据体背景颜色
///
/// 实体
/// 行
/// 字段
/// 颜色代码
private void SetEntityBackgoundColor(string entityKey, int row, string fieldKey = “”, string backgroundColor = “#FA8072”)
{
EntryGrid grid = this.View.GetControl(entityKey);
List<KeyValuePair<int, string>> backgroundList = new List<KeyValuePair<int, string>>();
backgroundList.Add(new KeyValuePair<int, string>(row, backgroundColor));
if (fieldKey.IsEmpty())
{
grid.SetRowBackcolor(backgroundList);

            IDynamicFormState formState = this.View.GetService<IDynamicFormState>();
            formState.AftInvokeControlMethod(grid.ControlAppearance, "UpdateFieldStates",
                new JSONObject() {
                    {
                        "backcolor", new JSONObject() {
                            { row.ToString(), backgroundColor }
                        }
                    }
                });

        }
        else
        {
            grid.SetCellsBackcolor(fieldKey, backgroundList);//设置单元格背景颜色
        }
    }

项目代码调用案例：

//加载事件
public override void OnLoad(EventArgs e)
{
base.OnLoad(e);
Entity entity = this.View.BillBusinessInfo.GetEntity(“FTreeEntity”);
DynamicObjectCollection rows = this.Model.GetEntityDataObject(entity);
for (int i = 0; i < rows.Count - 1; i++)
{
//行标识一致，则是变更前和变更后 替代物料
if (rows[i][“RowId”].ToString() == rows[i + 1][“RowId”].ToString())
{
string MATERIALID1 = ((DynamicObject)rows[i][“MATERIALIDCHILD”])[“Id”].ToString();
string MATERIALID2 = ((DynamicObject)rows[i+1][“MATERIALIDCHILD”])[“Id”].ToString();

                //替换前数据行
                string sql = $"/*dialect*/ select FHeight from t_BD_MaterialBase where FMATERIALID = '{MATERIALID1}'";
                DynamicObjectCollection data1 = DBUtils.ExecuteDynamicObject(this.Context, sql);

                //替换后数据行
                string sql2 = $"/*dialect*/ select FHeight from t_BD_MaterialBase where FMATERIALID = '{MATERIALID2}'";
                DynamicObjectCollection data2 = DBUtils.ExecuteDynamicObject(this.Context, sql2);

                if (data1.Count > 0 && data2.Count > 0)
                {
                    //如果替换后物料行高 大于 替换前物料行高，两行数据变色
                    if (Convert.ToDouble(data1[0]["FHeight"]) < Convert.ToDouble(data2[0]["FHeight"]))
                    {
                    	//单据体标识，行，颜色
                        SetEntityBackgoundColor("FTreeEntity", i, "", "#FF0000");
                        SetEntityBackgoundColor("FTreeEntity", i + 1, "", "#FF0000");
                    }
                }

            }
        }

    }
