推荐答案

您将它们添加到模板中以显示数据.您的问题是，然后需要在页面加载之前添加它，以使viewstate起作用.

您从不在网格中搜索，而总是在搜索数据源.

dat不是一个单词.

You add them in your template for how the data is displayed. Your issue is, then need to be added before page load in order for viewstate to work.

You never search in your grid, you always search your data source.

dat is not a word.

Christian正确地将文本框添加到数据网格.以下是可帮助您的代码示例:

Christian is right regarding adding textbox to the datagrid. Below is code sample to help you:

<asp:datagrid id="dg" runat="server" autogeneratecolumns="false" xmlns:asp="#unknown">
            <columns>
                <asp:boundcolumn datafield="id"></asp:boundcolumn>
                <asp:templatecolumn>
                    <itemtemplate>
                        <asp:textbox id="txt" runat="server" text="<%#DataBinder.Eval(Container.DataItem,"name") %>"></asp:textbox>
                    </itemtemplate>
                </asp:templatecolumn>
            </columns>
        </asp:datagrid>

要读取文本框数据，您需要首先找到每一行的控件.以下示例可能会为您提供帮助:

To read textbox data you need to first find the control for each row. Below sample may help you:

// Loop through the datagrid rows
foreach (DataGridItem item in dg.Items)
{
    // Get textbox corresponding to the row
    TextBox a= item.FindControl("txt") as TextBox;
    if (a != null)
    {
        // Your logic to access the textbox
    }
}

这用于服务器端代码.您还可以在客户端访问网格的控件(建议使用JQuery).

This is for server side code. You can also access the grid''s controls at client side (JQuery recommended).
