在插入模式下插入不在detailview上工作的记录

Question

我有一个包含多个字段的详细信息视图，并且始终仅在插入模式下使用。我遇到的问题是当我将所有值输入到我的详细信息视图中并点击插入按钮时没有任何反应。那么屏幕会刷新，但没有新的记录插入到表中。

这是我的aspx代码：

            <td class="style2" colspan="2">
                <asp:DetailsView ID="DetailsView1" runat="server" 
                DataSourceID="ObjectDataSource1" DataKeyNames="requestid"
                Height="29px" Width="928px" AutoGenerateRows="False" CellPadding="4" ForeColor="#333333"
                GridLines="None" Style="margin-right: 0px; text-align: left; margin-top: 0px;" 
                    ondatabound="DetailsView1_DataBound" 
                    onitemcommand="DetailsView1_ItemCommand" 
                    oniteminserting="DetailsView1_ItemInserting" >
                <Fields>
                    <asp:TemplateField AccessibleHeaderText="Request ID" HeaderText="Leave Request ID" Visible="False">
                        <EditItemTemplate>

                        <InsertItemTemplate>

Answer 1

在添加记录后，DetailsView1.DataBind();中缺少详细信息DetailsView1_ItemInserting，请调用DetailsView1.DataBind();方法。

protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
           // do your work 
          // .........
          //...... 
    DetailsView1.DataBind();
}

Answer 2

添加此代码以便在添加数据后进行绑定

void DetailsView1_ItemInserted(object sender, 
    DetailsViewInsertedEventArgs e)
  {
    // Refresh the GridView control after a new record is inserted 
    // in the DetailsView control.
    DetailsView1.DataBind();
  }

并将其添加到您的控件OnItemInserted="DetailsView1_ItemInserted"
