MSDN ASP.NET GridView 範例集 Group Row 部份程式碼修正

 

  可能因為排版緣故,導致刊登於MSDN上的ASP.NET GridView 範例集中Group Row的部份程式碼有錯誤,

 特於此列出正確的程式碼(主要是泛型List的泛型參數問題,由於使用了<,> 符號,可能於排版時漏掉了).

 

Group Row 程式碼

private void PrepareGroup() {       int lastSupID = -1;       GridViewRow currentRow = null;       List<GridViewRow>  tempModifyRows = new List<GridViewRow>();       foreach (GridViewRow row in GridView1.Rows)       {                     if (row.RowType == DataControlRowType.DataRow)          {             if (currentRow == null)             {                 currentRow = row;                 int.TryParse(row.Cells[2].Text, out lastSupID);                 continue;             }             int currSupID = -1;             if (int.TryParse(row.Cells[2].Text, out currSupID))             {                if (lastSupID != currSupID)                {                   currentRow.Cells[2].Attributes["rowspan"] = (tempModifyRows.Count+1).ToString();                   currentRow.Cells[2].Attributes["valign"] = "center";                                          foreach (GridViewRow row2 in tempModifyRows)                      row2.Cells.RemoveAt(2);                   lastSupID = currSupID;                   tempModifyRows.Clear();                   currentRow = row;                   lastSupID = currSupID;                }                else                   tempModifyRows.Add(row);         }                       } }   if (tempModifyRows.Count > 0)   {        currentRow.Cells[2].Attributes["rowspan"] = (tempModifyRows.Count + 1).ToString();        currentRow.Cells[2].Attributes["valign"] = "center";        foreach (GridViewRow row2 in tempModifyRows)             row2.Cells.RemoveAt(2);   } } protected void GridView1_PreRender(object sender, EventArgs e) {     PrepareGroup(); }
