動態填充數據網格

Question

while (rawCode.IndexOf("<a href") != -1) 
{ 
       string[] parts = link.Split(new string[] { "./" }, StringSplitOptions.None); 
       string column = string.Format("Column{0}",1); 
       dataGridView1.Columns.Add("Link","Links"); 
       for (int i = 0; i < parts.Length; i++) 
       { 
        if (parts[i] != "") 
        { 

         dataGridView1.Rows.Add((new Object[] { i, parts[i]})); 

         dataGridView1.Columns.Add("Link", "Name"); 
         dataGridView1.Rows.Add((new Object[] { i, parts[i]})); 
         //Here i need to insert data into already existing row. 
        } 
       } 
} 

我可以使用上面的代碼動態地創建一行。但我沒有得到如何將數據插入已經創建的行。下圖顯示了上述代碼的輸出。

我想添加鏈接後單元格旁邊的數據。當我試圖使用相同的代碼，新的行正在創建，但我想插入數據到已經創建的行。

您可以更新現有的行，像這樣：

dataTable.Rows[i]["columnNameHere"] = valueYouWantToUse; 

另外，您可以輸入該行中的信息之前，將其添加到數據源。

DataRow row = dataTable.NewRow(); 
row["columnName"] = valueYouWantToUse; 
//any other information can be put here too, for each column in the row. 
dataTable.Rows.Add(row); 

if (parts[i] != "") 
       { 

        dataGridView1.Rows.Add((new Object[] { i, parts[i]})); 

        dataGridView1.Columns.Add("Link", "Name"); 
        DataRow row = dataTable.NewRow(); 
        row["Link"] = i.ToString(); 
        row["Name"] = parts[i].ToString(); 

        //here add all your column values for that row in the same manner, then, 
        dataTable.Rows.Add(row); 
       }
