C# 使用JSGrid控件的甘特图

我正在尝试使用共享点控件创建甘特图生成器：

<Sharepoint:JsGrid>

（此代码来自教程中的答案）

在钥匙里，我要放什么？如果有人做了或者知道怎么做，那就太好了。

不确定你是否仍然面临这个问题。但这是我们为

前辈

专栏所做的，据我所知：

1] 稍微更改依赖项类以添加一个构造函数，如图所示（否则会出错）

2] 然后，基本上需要将一个

依赖项

数组传递给

前置项

列，这意味着JSGrid控件需要知道依赖项的起点/行和终点/行（因此需要一个数组）。由于继承和

ToJson

方法，JSON序列化已经得到了处理，因此无需担心

代码：

1] 依赖类：

public class Dependency : IJsonSerializable
{
    public object Key { get; set; } // recordKey
    public LinkType Type { get; set; } // SP.JsGrid.LinkType

    public Dependency() {
        Key = DBNull.Value;
        Type = LinkType.FinishStart;
    }

    public string ToJson(Serializer s)
    {
        return JsonUtility.SerializeToJsonFromProperties(s, this);
    }
}

2] 如果不是针对SharePoint任务列表（其中数据是DataTable的对象），则添加列：

3] 将右对象数组设置为

preventors

列：

    if (<<A predecessor exists>>){
    Dependency[] dep = new Dependency[2];
    dep[0] = new Dependency();
    try{
        /*
        // Unique Identifier for your row based on what you are 
        // passing to the GridSerializer while initializing it 
        // (as a third parameter which is called keyColumnName)
        // In my case I had to get it by doing some coding as  
        // shown. The first object in the array represents the 
        // previous row and so the unique identifier should  
        // point to the previous row
        */
        dep[0].Key = (
                data.Select(
                    "ID=" + 
                    data.Rows[s]["PredecessorsID"].ToString()
                    )
                    [0]["Key"]
                );
    }catch (Exception ex){ 
        dep[0].Key = DBNull.Value; 
    }
    dep[0].Type = LinkType.FinishStart;

    /*
    // Unique Identifier for your row based on what you are 
    // passing to the GridSerializer while initializing it 
    // (as a third parameter which is called keyColumnName)
    // In my case I had to get it by doing some coding as  
    // shown. The second object in the array represents the 
    // current row and so the unique identifier should  
    // point to the current row
    */
    dep[1] = new Dependency();
    try{ 
        dep[1].Key = data.Rows[s]["Key"]; 
    }catch (Exception ex){ 
        dep[0].Key = DBNull.Value; 
    }
    dep[1].Type = LinkType.StartFinish;
    data.Rows[s]["Predecessors"] = dep;
}

确保StartFinish和FinishStart链接类型与正确的行相匹配，并且任务正确列出，任务开始日期、任务结束日期和前置键正确

data.Columns.Add(new DataColumn("Predecessors",typeof(Dependency[])));

    if (<<A predecessor exists>>){
    Dependency[] dep = new Dependency[2];
    dep[0] = new Dependency();
    try{
        /*
        // Unique Identifier for your row based on what you are 
        // passing to the GridSerializer while initializing it 
        // (as a third parameter which is called keyColumnName)
        // In my case I had to get it by doing some coding as  
        // shown. The first object in the array represents the 
        // previous row and so the unique identifier should  
        // point to the previous row
        */
        dep[0].Key = (
                data.Select(
                    "ID=" + 
                    data.Rows[s]["PredecessorsID"].ToString()
                    )
                    [0]["Key"]
                );
    }catch (Exception ex){ 
        dep[0].Key = DBNull.Value; 
    }
    dep[0].Type = LinkType.FinishStart;

    /*
    // Unique Identifier for your row based on what you are 
    // passing to the GridSerializer while initializing it 
    // (as a third parameter which is called keyColumnName)
    // In my case I had to get it by doing some coding as  
    // shown. The second object in the array represents the 
    // current row and so the unique identifier should  
    // point to the current row
    */
    dep[1] = new Dependency();
    try{ 
        dep[1].Key = data.Rows[s]["Key"]; 
    }catch (Exception ex){ 
        dep[0].Key = DBNull.Value; 
    }
    dep[1].Type = LinkType.StartFinish;
    data.Rows[s]["Predecessors"] = dep;
}
