如何使listview项拖放。

问题描述

创建列表视图并绑定到Radlist视图。单击列表视图项时，我可以将文本框控件插入到表格单元格中（动态生成表格），实际上我必须拖动列表视图项目并将控件放入表格单元格中。在这种情况下，我将文本框控件插入零索引。有人可以帮帮我，我该怎么办？



谢谢，问候。



注意：尝试像vs工具箱一样创建。



我尝试过：



脚本：

Creating a listview and bind to Radlist view. On clicking of listview item i am able insert the textbox control into a tablecell (generated table dynamically), actually i have to drag the listview item and drop the control into table cells. In this case i am inserting the textbox control at zero index. can someone help me out, how can i do this??

Thanks, regards.

Note: Trying to create same like vs toolbox.

What I have tried:

Script:

function GetDynamicTextBox(value) {
                    return '<input name = "DynamicTextBox" type="text" value = "' + value + '" />';

 function StepChange() {
                    var table = document.getElementById('myTable');
                    table.rows['0'].cells['0'].innerHTML = GetDynamicTextBox("");
                }
                function insertData() {
                    $find('<%=RadAjaxManager1.ClientID%>').ajaxRequest('InsertClick');
                }
