问题描述
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"><asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowCancelingEdit="GridView1_RowCancelingEdit" OnRowDeleting="GridView1_RowDeleting" OnRowEditing="GridView1_RowEditing" OnRowUpdating="GridView1_RowUpdating" >
<Columns>
<asp:BoundField DataField="player_name" HeaderText="name" />
<asp:BoundField DataField="score" HeaderText="score" />
<asp:BoundField DataField="address" HeaderText="address" />
<asp:TemplateField HeaderText="photo">
<ItemTemplate>
<asp:Image ImageUrl= <%#Eval("photo") %> runat="server" ToolTip= <%#Eval("player_name") %> AlternateText="image not found" Height="100" Width="100" />
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="true" ShowCancelButton="true" ShowDeleteButton="true" ShowInsertButton="true" ShowSelectButton="true" />
</Columns>
</asp:GridView></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"])
