c# - 在插入模式下插入不在详细信息视图上的记录

Question

我有一个具有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。好吧，屏幕已刷新，但表中没有插入新记录。

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" >

Answer 1

DetailsView1.DataBind();在DetailsView1_ItemInserting添加记录调用该DetailsView1.DataBind();方法后，您缺少详细信息。

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中OnItemInserted="DetailsView1_ItemInserted"
