如何閱讀網

Question

我試圖用刀尖在網格上的每一行顯示細節每當在特定的小區用戶所指向的每一行。它應該顯示每一行的細節，但它只顯示第一行的細節。誰能幫我？

for (int i = 1; i <= e.Row.Cells.Count - 1; i++) 
{ 
    if (e.Row.Cells[i].Text == "0" || string.IsNullOrEmpty(e.Row.Cells[i].Text) || e.Row.Cells[i].Text == "&nbsp;") 
    { 
     e.Row.Cells[i].Text = ""; 
    } 
    else 
    { 
     e.Row.Cells[i].BackColor = System.Drawing.Color.Blue; 

     dateSetExport.Tables.Clear(); 
     dateSetExport.Reset(); 
     SqlParameter[] param = new SqlParameter[2]; 
     param[1] = new SqlParameter("@Startdate", gvDetails.HeaderRow.Cells[i].Text); 
     param[0] = new SqlParameter("@Employe_Id", e.Row.Cells[0].Text.Split('-')[0]); 
     DataTable dt1 = DataHelper.getDataTableExecuteSP("usp_GetToolTip", param); 
     dt1.TableName = "ToolTip"; 
     dateSetExport.Tables.Add(dt1); 
     string tooltip = ""; 
     for (int j = 0; j < dt1.Rows.Count; j++) 
     { 
      tooltip = tooltip + dt1.Rows[j]["normal_working_hours"].ToString() + " Hours : " + dt1.Rows[j]["description"].ToString()+"\n\n"; 
     } 
     e.Row.Cells[i].ToolTip = tooltip; 
    } 
}

您可以使用其他的foreach以循環的所有行：

foreach (GridViewRow row in GridView.Rows) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     //do your staff 
    } 
} 

但對我來說，你應該使用GridView_RowDataBound事件：

protected void GridView_RowDataBound(Object sender, GridViewRowEventArgs e) 
{ 
    if (e.Row.RowType == DataControlRowType.DataRow) 
    { 
     for (int i = 1; i <= e.Row.Cells.Count - 1; i++) 
     { 
     if (e.Row.Cells[i].Text == "0" || string.IsNullOrEmpty(e.Row.Cells [i].Text) || e.Row.Cells[i].Text == "&nbsp;") 
     { 
    e.Row.Cells[i].Text = ""; 
      } 
    else 
    { 
     e.Row.Cells[i].BackColor = System.Drawing.Color.Blue; 

     dateSetExport.Tables.Clear(); 
     dateSetExport.Reset(); 
     SqlParameter[] param = new SqlParameter[2]; 
     param[1] = new SqlParameter("@Startdate", gvDetails.HeaderRow.Cells[i].Text); 
     param[0] = new SqlParameter("@Employe_Id", e.Row.Cells[0].Text.Split('-')[0]); 
     DataTable dt1 = DataHelper.getDataTableExecuteSP("usp_GetToolTip", param); 
     dt1.TableName = "ToolTip"; 
     dateSetExport.Tables.Add(dt1); 
     string tooltip = ""; 
     for (int j = 0; j < dt1.Rows.Count; j++) 
     { 
     tooltip = tooltip + dt1.Rows[j]["normal_working_hours"].ToString() + " Hours : " + dt1.Rows[j]["description"].ToString()+"\n\n"; 
     }`enter code here` 
     e.Row.Cells[i].ToolTip = tooltip; 
     } 
    } 
    } 
    }
