Question

我试图用刀尖在网格上的每一行显示细节每当在特定的小区用户所指向的每一行。它应该显示每一行的细节，但它只显示第一行的细节。谁能帮我？

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以循环的所有行：

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

但对我来说，你应该使用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; 
     } 
    } 
    } 
    }
