如何將行刪除按鈕連接到我的GridView_RowDeleted事件？

Question

我創建了一個GridView，並設置其標題：

<asp:GridView ID="ProductsGridView" 
    DataSourceID="ProductsDataSource" 
    AllowPaging="True" 
    AutoGenerateColumns="False" 
    runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" 
    AutoGenerateDeleteButton="True" 
    AutoGenerateEditButton="True" 
    OnRowCancelingEdit="GridView1_RowCancelingEdit" 
    OnRowUpdating="GridView1_RowUpdating" 
    OnRowEditing="GridView1_RowEditing" 
    OnRowDeleted="ProductsGridView_RowDeleted" 
    onselectedindexchanged="ProductsGridView_SelectedIndexChanged"> 

我可以看到在網格中的刪除按鈕，但是當我上雙擊按鈕時，Visual Studio帶我到：

protected void ProductsGridView_SelectedIndexChanged(object sender, EventArgs e) 

代替：

protected void ProductsGridView_RowDeleted(object sender, GridViewDeletedEventArgs e). 

這個事件沒有對發送行信息。我錯過了什麼？

Answer 1

我通常做到以下幾點：

<asp:GridView ID="ProductsGridView" 
    DataSourceID="ProductsDataSource" 
    AllowPaging="True" 
    AutoGenerateColumns="False" 
    runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" 
    AutoGenerateDeleteButton="True" 
    AutoGenerateEditButton="True" 
    OnRowCancelingEdit="GridView1_RowCancelingEdit" 
    OnRowUpdating="GridView1_RowUpdating" 
    OnRowEditing="GridView1_RowEditing" 
    onrowdeleting="GridView1_RowDeleting" 

protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e) 
{ 

}

我寧願建議你一個簡單的方法，如果您擔心刪除而已，沒有價值觀的內聯編輯在網格本身。

<asp:GridView ID="ProductsGridView" DataSourceID="ProductsDataSource" 
       AllowPaging="True" AutoGenerateColumns="False" 
       runat="server" CellPadding="4" ForeColor="#333333" GridLines="None" 
       AutoGenerateEditButton="True" OnRowCommand="Gridview1_RowCommand"> 
    <columns> 
     <table> 
      <tr> 
      <td> col1val1 </td> 
      <td> col1val1 </td> 
      <td> col1val1 </td> 
      <td> col1val1 </td> 
      <td> col1val1 </td> 
      <td> <asp:Button Id="btnDelete" CommandName="DeleteRow" 
        CommandArgument='<%#Eval("PrimaryKeyFromTheDataSource") %>' 
       Text="Delete" Tooltip="DeleteCurrentRow" 
       onclientclick='return confirm("Are you certain to delete?");'/> 
      </td> 

      </tr> 
     </table> 
    <columns> 
</asp:Gridview>` 

C＃ - 行命令事件

int i = Convert.ToInt32(e.CommandArgument); 
if(e.commandname.equals("deleterow")) 
{ 
    DeleteItemById(i); 

}

Protected void CustomersGridView_RowDeleting(Object sender, GridViewDeleteEventArgs e) 
{ 
    TableCell cell = CustomersGridView.Rows[e.RowIndex].Cells[2]; 
    if (cell.Text == "Beaver") 
    { 
     e.Cancel = true; 
     Message.Text = "You cannot delete customer Beaver."; 
    } 
    else 
    { 
     Message.Text = ""; 
    } 
} 
<asp:GridView ID="CustomersGridView" runat="server" 
    DataSourceID="CustomersSqlDataSource" 
    AutoGenerateColumns="False" 
    AutoGenerateDeleteButton="True" 
    OnRowDeleting="CustomersGridView_RowDeleting" 
    DataKeyNames="CustomerID,AddressID"> 
    <Columns> 
     <asp:BoundField DataField="FirstName" 
      HeaderText="FirstName" SortExpression="FirstName" /> 
     <asp:BoundField DataField="LastName" HeaderText="LastName" 
      SortExpression="LastName" /> 
     <asp:BoundField DataField="City" HeaderText="City" 
      SortExpression="City" /> 
     <asp:BoundField DataField="StateProvince" HeaderText="State" 
      SortExpression="StateProvince" /> 
    </Columns> 
</asp:GridView>
