I have dynamic list item. 我有动态列表项。 This list is not static. 此列表不是静态的。 In view of the necessity, I will have at least one/more list. 鉴于必要性,我将至少有一个/多个列表。 what I need is, I gotta split that list into at least two unique records. 我需要的是,我必须将该列表分成至少两个独特的记录。 This I can part. 我可以参加。 Yet, I need to bind this list into datagridview. 但是,我需要将此列表绑定到datagridview。
This is my code: I have two list, 这是我的代码:我有两个列表,
List<string> list1=new List<string>();
list1.add("THE BOOK OF BURGER");
list1.add("The Hogwarts Library");
list1.add("NEW Day in the Life of a Farmer");

list4.. etc..
I have Datagridview. 我有Datagridview。 I want to bind this into data grid view as, 我想将其绑定到数据网格视图中,

You can create a BooK
class and shape your data in a List<Book>
and bind the grid to the list. 您可以在List<Book>
创建BooK
类并对数据进行整形,并将网格绑定到列表中。
Book 书
public class Book
{
public string Title { get; set; }
public string Price { get; set; }
}
Bind data to DataGridView 将数据绑定到DataGridView
var list = new List<Book>();
for (int i = 0; i < list1.Count; i++)
{
list.Add(new Book()
{
Title = list1[i],
Price = list2[i]
});
}
this.dataGridView1.AutoGenerateColumns = true;
this.dataGridView1.DataSource = list;
Based on comments, I suppose you have a Dictionary<String, List<String>>
and you want to add them dynamically to the grid. 基于注释,我想你有一个Dictionary<String, List<String>>
,你想要动态地将它们添加到网格中。
I suppose you will use the key of dictionary as header text for the column. 我想你会使用字典的键作为列的标题文本。
//Add your lists to the dictionary
var dictionary = new Dictionary<string, List<string>>();
dictionary.Add("list1", list1);
dictionary.Add("list2", list2);
// And some othet lists ....
//Calculate the count of rows.
int rowCount = dictionary.Cast<KeyValuePair<string, List<string>>>()
.Select(x=>x.Value.Count).Max();
//Create the data table and for each table, add a column
var dataTable = new DataTable();
foreach (var key in dictionary.Keys)
{
dataTable.Columns.Add(key);
}
//Add items of each list to the columns of rows of table
for (int i = 0; i < rowCount; i++)
{
var row = dataTable.Rows.Add();
foreach (var key in dictionary.Keys)
{
try
{
row[key] = dictionary[key][i];
}
catch
{
row[key] = null;
}
}
}
//Show data in grid
this.dataGridView1.AutoGenerateColumns = true;
this.dataGridView1.DataSource = dataTable;
and here is the result: 这是结果:
I guess you need to make a DataTable
and add
data in it. 我想你需要创建一个DataTable
并在其中add
数据。
As you have the Lists
you can make a List
as column
of DataTable
and the data you are adding in List
will be row
of that column
. 如果您有Lists
,则可以将List
作为DataTable
column
,并且您在List
中添加的数据将是该column
row
。
DataTable dt = new DataTable();
dt.Columns.Add("Title");
DataRow dr = dt.NewRow();
dr["Title"] = "THE BOOK OF BURGER";
dt.Rows.Add(dr);
dt.Columns.Add("Price");
DataRow dr = dt.NewRow();
dr["Price"] = "$200";
dt.Rows.Add(dr);
grdBooks.DataSource = dt;
grdBooks.DataBind();
If you are receiving List
you can loop
through list
to add data in Rows
of DataTable
. 如果您收到List
,你可以loop
通过list
中添加数据Rows
的DataTable
。
