從SQL逗號分隔的字符串重新填充GridView中的複選框列表

Question

這是我的情況。

我從的CheckBoxList保存的數據：

foreach (ListItem li in CheckBoxList1.Items) 
{ 
    Steps = String.Join(", ", CheckBoxList1.Items.Cast<ListItem>() 
            .Where(i => i.Selected)); 
} 

它工作正常，但我要的是要回從這個數據庫中的數據一個CheckBoxList的DataGrid中。

波紋管是我嘗試過的很多東西。請幫助：

<div align="center" style="margin-top: 50px;">

private void Bind_CheckBoxList()

} 


    if (e.Row.RowType == DataControlRowType.DataRow)

        if (c != null) 
        { 
         Label test = (Label)(e.Row.FindControl("lblBrand")); 
         Steps = test.Text; 

         string[] items = Steps.Split(new[] { ", " }, StringSplitOptions.None); 

         foreach (ListItem li in c.Items) 
          li.Selected = items.Contains(li.Text); 

        } 
        dt = new DataTable("tbl"); 
        da.Fill(dt); 
       } 
      } 
      c.DataSource = dt; 
      c.DataTextField = what to write here to pass the array Text; 
      c.DataValueField = "SNo"; 
      c.DataBind(); 
     } 
    }

的C＃代碼嘿感謝我解決它通過建立的步驟所需文件另一個表和相同的,,,現在它的顯示checkBoxList，我想進入數據網格和波紋管代碼

if ((e.Row.RowState & DataControlRowState.Edit) == 0) 
     { 
      CheckBoxList c = (CheckBoxList)e.Row.FindControl("CheckBoxList2"); 
      CheckBoxList CheckBoxListDR = (CheckBoxList)e.Row.FindControl("CheckBoxList3"); 
      DataTable dt; 
      String SQL = "SELECT distinct S.Steps, D.DocumentsRequired, T.TransactionID FROM [StepsIsSelectedTable] S JOIN TransactionDetail T " + 
       " ON S.TransactionIDSteps = T.TransactionID JOIN DocumentsRequiredIsSelected D " + 
       "ON D.TransactionIDDR = T.TransactionID WHERE " + 
       "TransactionIDDR ='" + TreeView1.SelectedValue + "' and S.StepsIsSelected='True' and D.DocumentsRequiredIsSelected='True'" + 
       " group by S.Steps, D.DocumentsRequired ,T.TransactionID"; 

      string sConstr = ConfigurationManager.ConnectionStrings["conStr"].ConnectionString; 
      using (SqlConnection conn = new SqlConnection(sConstr)) 
      { 
       using (SqlCommand comm = new SqlCommand(SQL, conn)) 
       { 
        conn.Open(); 
        using (SqlDataAdapter da = new SqlDataAdapter(comm)) 
        { 
         dt = new DataTable("tbl"); 
         da.Fill(dt); 
        } 
       } 

       c.DataSource = dt; 
       CheckBoxListDR.DataSource = dt; 
       c.DataTextField = "Steps"; 
       c.DataValueField = "TransactionID"; 
       CheckBoxListDR.DataTextField = "DocumentsRequired"; 
       CheckBoxListDR.DataValueField = "TransactionID"; 
       c.DataBind(); 
       c.SelectedValue = "TransactionID"; 
       CheckBoxListDR.DataBind(); 
       CheckBoxListDR.SelectedValue = "1"; 
      } 
     }
