如何使用Ajax ModalPopUpExtender控件在ListView中获取所选行的ID? [英] How to get the ID of the selected row in the ListView with Ajax ModalPopUpExtender control?

问题描述

我有一个ListView，其中显示了员工提交的建议.在此ListView的最后一列中，我有一个(状态)列，该列将由管理员更新.当管理员单击它时，将打开带有RadioButtonList的ModalPopUpExtender，其中显示(Status)的可能选项.无论如何，我现在需要获取管理员单击该建议的状态"单元格的行的ID.我需要在以后使用它向该建议的所有者发送电子邮件通知.
除了GridView控件，我已经做了所有这些事情，如下所示:

I have a ListView that shows the suggestions submitted by the employees. In the last column of this ListView, I have a (Status) column that will be updated by the Admin. When the Admin clicks on it, a ModalPopUpExtender will be opened with RadioButtonList that shows the possible options for (Status). Anyway, I need now to get the ID of the row where the Admin clicked on the Status cell of that suggestion. I need in order to use it later on for sending an email notification to the owner of that suggestion.
I already did of all this but for GridView control as following:

protected void lnkSuggestionStatus_Click(object sender, EventArgs e)
    {
        LinkButton lnkSuggestionStatus = sender as LinkButton;

        //var safetySuggestionsId =

        //get reference to the row selected
        GridViewRow gvrow = (GridViewRow)lnkSuggestionStatus.NamingContainer;

        //set the selected index to the selected row so that the selected row will be highlighted
        GridView1.SelectedIndex = gvrow.RowIndex;

        //This HiddenField used to store the value of the ID
        HiddenField1.Value = GridView1.DataKeys[gvrow.RowIndex].Value.ToString();
        //ViewState["Username"] = gvrow.Cells[4].Text;

        //show the modalPopUp
        modalPopUpExtender1.Show();
    }

但是我现在需要它用于ListView， **所以该怎么做?**

当前隐藏代码:

But I need it now for the ListView, **so How to do that?**

Current Code-Behind:

protected void lnkSuggestionStatus_Click1(object sender, EventArgs e)
    {
        LinkButton lnkSuggestionStatus1 = sender as LinkButton;

        //show the modalPopUp
        modalPopUpExtender2.Show();
    }

推荐答案

您需要设置ListView的DataKeyNames，然后

You need to set DataKeyNames of your ListView and then

protected void lnkSuggestionStatus_Click1(object sender, EventArgs e)
    {
        ListViewDataItem item = (ListViewDataItem)(sender as Control).NamingContainer;
        string idValue= ListView1.DataKeys[item.DataItemIndex].Value.ToString();

    }
