Question

我有三个列名称，比率，类别的网格视图

我也在这里使用ajax rate和edittemplate中的一个下拉列表，它与sqldatasource绑定。

但是当点击编辑时，它没有显示下拉列表。

请帮助解决这个问题。

代码是

<asp:gridview id="GVTweet" runat="server" allowpaging="True" allowsorting="True"
    autogeneratecolumns="False" gridlines="None" pagesize="15" width="700px" onselectedindexchanged="GVTweet_SelectedIndexChanged"
    onrowcancelingedit="GVTweet_RowCancelingEdit" onrowediting="GVTweet_RowEditing"
    onrowupdated="GVTweet_RowUpdated" onrowupdating="GVTweet_RowUpdating">
        <HeaderStyle />
        <AlternatingRowStyle Height="70px" />
        <RowStyle Height="70px" />

Answer 1

尝试在gridview上声明DataKeyNames属性。

<asp:GridView ID="GVTweet" runat="server" DataKeyNames="PrimaryKeyName"...

Answer 2

像这样使用并更改数据源解决了我的问题

Answer 3

试试这个

    protected void GVTweet_RowEditing(object sender, GridViewEditEventArgs e)
    {
            GVTweet.EditIndex = e.NewEditIndex;

            //Load Grid
    }

<asp:gridview id="GVTweet" runat="server" allowpaging="True" allowsorting="True"
autogeneratecolumns="False" gridlines="None" pagesize="15" width="700px"     onselectedindexchanged="GVTweet_SelectedIndexChanged"
onrowcancelingedit="GVTweet_RowCancelingEdit" onrowediting="GVTweet_RowEditing"
onrowupdated="GVTweet_RowUpdated" onrowupdating="GVTweet_RowUpdating">

gridview edittemplate不显示内容
