Question

我目前正在使用两个内容占位符来显示列表项的标题和摘要。 Currenlty我只显示2个列表项的标题和摘要。我希望能够在后面的代码中创建一个表来生成行和单元格，而不是使用占位符，这些行和单元格显示了在for循环中指定的列表项目的标题和摘要。下面的代码显示了我当前在代码beheind中创建表的方法，但还没有弄清楚如何将它连接到for循环中我当前必须显示列表项：

//for loop to iterate through the list retrieving the required amount of lits items
//the number of times to iteratie through the loop will be specified by the user using 
//the custom property
if (this.WebPart != null & this.WebPart.ListName != null & 
!this.WebPart.OverviewArticle)
{
string Listname = this.WebPart.ListName; //get the value of the ListName custom 
property
int publicationNumberofitems = this.WebPart.pubNumOfItems; //get the value of the 
                                                           //pubNumOfItems as int

//since the first iten in the list is 0 (making this variable -1 cause the correct 
//amount of details to be displayed based on the number
//provided via the pubNumOfItems custom property. So if a value of 2 is provided then 
//only two items will be displayed and so on.
int listItemsNumber = publicationNumberofitems - 1;

SPWeb web = SPContext.Current.Web;
SPList list = web.Lists[Listname];

SPListItemCollection collListItems = list.Items;

//creating a table to hold the list items in the for loop. This will replace the use 
//of the placeholders
Table table1 = new Table();
TableRow tr = new TableRow();
TableCell tc = new TableCell();



//for loop to iterate through the list retrieving the required amount of lits items
//the number of times to iteratie through the loop will be specified by the user using 
//the custom property
for (int i = 0; i < listItemsNumber && i < collListItems.Count; i++)
{
SPListItem listItems = collListItems[i];

string title1 = (string)collListItems[i]["Title"];
string summary1 = (string)collListItems[i]["Summary"];

//generating the table rows and cell is not currenlty working               
tr.Cells.Add(tc);
tc.Controls.Add(new LiteralControl(title1));

//placeholders are no longer required, a table with rows and cells generated by the 
//for loop is required instead
//plhPubTitleHyper.Controls.Add(new LiteralControl(title1));
//plhPubSummary.Controls.Add(new LiteralControl(summary1));

}

}

对此的任何帮助将不胜感激。提前致谢

更新代码：

//creating a table to hold the list items in the for loop. This will replace the use  
//of the placeholders
Table table1 = new Table();
TableRow tr = null;

//for loop to iterate through the list retrieving the required amount of lits items
//the number of times to iteratie through the loop will be specified by the user using 
//the custom property
for (int i = 0; i < listItemsNumber && i < collListItems.Count; i++)
{
SPListItem listItems = collListItems[i];

string title1 = (string)collListItems[i]["Title"];
//string summary1 = (string)collListItems[i]["Summary"];


tr = new TableRow();

TableCell c1 = new TableCell();
TableCell c2 = new TableCell();

c1.Controls.Add(new LiteralControl(title1));
//c2.Controls.Add(new LiteralControl(summary1));//This needs to be in another row

tr.Cells.Add(c1);
//tr.Cells.Add(c2);

table1.Rows.Add(tr);

//plhPubTitleHyper.Controls.Add(new LiteralControl(table1));

//plhPubTitleHyper.Controls.Add(new LiteralControl(title1));
//plhPubSummary.Controls.Add(new LiteralControl(summary1));

}

plhPubTitleHyper.Controls.Add(table1);
}

更新的代码有效，但我现在需要能够添加行并将摘要放在不同的行中，而不是放在同一行的列中。

    Table table1 = new Table();
    TableRow tr = null;

    for (int i = 0; i < 5; i++) {
       tr = new TableRow();

       //You can also do a loop for the cell
       TableCell c1 = new TableCell();
       TableCell c2 = new TableCell();
       TableCell c3 = new TableCell();

       c1.Text = "Cell One";
       c2.Text = "Cell Two";
       c3.Text = "Cell Three";

       tr.Cells.Add(c1);
       tr.Cells.Add(c2);
       tr.Cells.Add(c3);

       table1.Rows.Add(tr);
    }

    form1.Controls.Add(table1);

在后面的代码中使用for循环创建表
