我的gridview是这样的，我正在使用命令字段 < pre lang = xml > & lt; asp：GridView ID =& quot ; GridView1&安培; QUOT; RUNAT =安培; QUOT;服务器&安培; QUOT;的AutoGenerateColumns =安培; QUOT假安培; QUOT; OnRowCancelingEdit =安培; QUOT; GridView1_RowCancelingEdit&安培; QUOT; OnRowDeleting =安培; QUOT; GridView1_RowDeleting&安培; QUOT; OnRowEditing =安培; QUOT; GridView1_RowEditing&安培; QUOT; OnRowUpdating =安培; QUOT; GridView1_RowUpdating&安培; QUOT; & gt; & lt; Columns& gt; & lt; asp：BoundField DataField =& quot; player_name& quot;的HeaderText =安培; QUOT;名称&安培; QUOT; /&安培; GT; & lt; asp：BoundField DataField =& quot;得分& quot;的HeaderText =安培; QUOT;得分&安培; QUOT; /&安培; GT; & lt; asp：BoundField DataField =& quot; address& quot;的HeaderText =安培; QUOT;地址&安培; QUOT; /&安培; GT; & lt; asp：TemplateField HeaderText =& quot; photo& quot;& gt; & lt; ItemTemplate& gt; & lt; asp：Image ImageUrl =& lt;％＃Eval（& quot; photo& quot;）％& gt; RUNAT =安培; QUOT;服务器&安培; QUOT; ToolTip =& lt;％＃Eval（& quot; player_name& quot;）％& gt; AlternateText =& quot; image not found& quot;高度=安培; QUOT; 100&安培; QUOT;宽度=安培; QUOT; 100&安培; QUOT; /&安培; GT; & lt; / ItemTemplate& gt; & lt; / asp：TemplateField& gt; & lt; asp：CommandField ShowEditButton =& quot; true& quot; ShowCancelButton =安培; QUOT;真&安培; QUOT;的ShowDeleteButton =安培; QUOT;真&安培; QUOT; ShowInsertButton =安培; QUOT;真&安培; QUOT; ShowSelectButton =安培; QUOT;真&安培; QUOT; /&安培; GT; & lt; / Columns& gt; & lt; / asp：GridView& gt; < / pre > 和代码隐藏我正在尝试的是 < pre lang = cs > 受保护void GridView1_RowUpdating（object sender，GridViewUpdateEventArgs e） { string name =（GridView1.Rows [e.RowIndex] .Cells [0]）。Text; int score = Convert.ToInt32（GridView1.Rows [e.RowIndex] .Cells [1] .Text）; string adress = GridView1.Rows [e.RowIndex] .Cells [2] .Text; updateTheRow（姓名，得分，地址）; } < / pre > 其中updateTheRow是我更新数据库记录的方法。

解决方案

首先改进你的问题。 可能你需要这个 DataRowView datarow = e.Row.DataItem int qty =转换。 ToDouble（datarow.Row [ Order_QTY]）

my gridview is like this and i am using command field <pre lang="xml">&lt;asp:GridView ID=&quot;GridView1&quot; runat=&quot;server&quot; AutoGenerateColumns=&quot;False&quot; OnRowCancelingEdit=&quot;GridView1_RowCancelingEdit&quot; OnRowDeleting=&quot;GridView1_RowDeleting&quot; OnRowEditing=&quot;GridView1_RowEditing&quot; OnRowUpdating=&quot;GridView1_RowUpdating&quot; &gt; &lt;Columns&gt; &lt;asp:BoundField DataField=&quot;player_name&quot; HeaderText=&quot;name&quot; /&gt; &lt;asp:BoundField DataField=&quot;score&quot; HeaderText=&quot;score&quot; /&gt; &lt;asp:BoundField DataField=&quot;address&quot; HeaderText=&quot;address&quot; /&gt; &lt;asp:TemplateField HeaderText=&quot;photo&quot;&gt; &lt;ItemTemplate&gt; &lt;asp:Image ImageUrl= &lt;%#Eval(&quot;photo&quot;) %&gt; runat=&quot;server&quot; ToolTip= &lt;%#Eval(&quot;player_name&quot;) %&gt; AlternateText=&quot;image not found&quot; Height=&quot;100&quot; Width=&quot;100&quot; /&gt; &lt;/ItemTemplate&gt; &lt;/asp:TemplateField&gt; &lt;asp:CommandField ShowEditButton=&quot;true&quot; ShowCancelButton=&quot;true&quot; ShowDeleteButton=&quot;true&quot; ShowInsertButton=&quot;true&quot; ShowSelectButton=&quot;true&quot; /&gt; &lt;/Columns&gt; &lt;/asp:GridView&gt;</pre> and in codebehind what i am trying is <pre lang="cs">protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { string name = (GridView1.Rows[e.RowIndex].Cells[0]).Text; int score = Convert.ToInt32(GridView1.Rows[e.RowIndex].Cells[1].Text); string adress = GridView1.Rows[e.RowIndex].Cells[2].Text; updateTheRow(name, score, adress); }</pre> where updateTheRow is my method to update the record in database.

解决方案

First improve your questions. May be you need this DataRowView datarow = e.Row.DataItem int qty = Convert.ToDouble(datarow.Row["Order_QTY"])
