Answer 2

RowDataBound事件中
     if (e.Row.RowType == DataControlRowType.DataRow)
     {
         e.attributs.add("onDblClick", "...")

Answer 3

onDblClick 后怎么办 ........ 关键部分省略 你真高

Answer 4

        <asp:TemplateField>
                                                        <ItemTemplate >
                                                            <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("InfManageID", "~/Web/InfManage/InfManageSee.aspx?InfManageID={0}") %>'
                                                                Text='<%# Eval("Title") %>' Target="_blank"></asp:HyperLink>
                                                            <asp:Image ID="ImageNew" runat="server"  visible="false" Width="25" Height="10" />
                                                            <asp:HiddenField ID="HF_ContentOrLink" runat="server" value='<%# Eval("ContentOrLink") %>'/>   
                                                        </ItemTemplate>
                                                        <ItemStyle Width="80%" />
                                                    </asp:TemplateField>
<%# Eval("Title") %>'  使用这个绑定 难道 非得 DataSourceID="SqlDataSource1" 不能直接从后台给定一个DT 绑定吗?

Answer 5

<Columns>   
    <asp:ButtonField Text="DoubleClick" CommandName="DoubleClick" 
                            Visible="false" />
</Columns>
rowdatabound中：
if (e.Row.RowType == DataControlRowType.DataRow)
{
    LinkButton _doubleClickButton = (LinkButton)e.Row.Cells[1].Controls[0];   
    string _jsDouble = ClientScript.GetPostBackClientHyperlink(_doubleClickButton, "");  
    e.Row.Attributes["ondblclick"] = _jsDouble;
}然后在RowCommand中判断CommandName

Answer 7

RowCommand中怎么写  问题是如何实现双击的那个单元格变成文本框

Answer 8

// 获得行索引
int _rowIndex = int.Parse(e.CommandArgument.ToString());
// 解析事件参数（在RowDataBound中增加的），从而获得被选中的列的索引
int _columnIndex = int.Parse(Request.Form["__EVENTARGUMENT"]);
// 设置GridView被选中的行的索引（每次回发后判断GridView1.SelectedIndex > -1则更新）
 _gridView.SelectedIndex = _rowIndex;
_gridView.DataBind();// 获得被选中单元格的显示控件并设置其不可见
 Control _displayControl = _gridView.Rows[_rowIndex].Cells[_columnIndex].Controls[..];
_displayControl.Visible = false;
// 获得被选中单元格的编辑控件并设置其可见
Control _editControl = _gridView.Rows[_rowIndex].Cells[_columnIndex].Controls[..];
_editControl.Visible = true;
