嘗試檢測gridview的哪一行處於編輯模式，然后在選中復選框字段時調整文本框

Question

我一直在研究實現此目的的幾種不同方法。 當前的一個嘗試使用jquery。

//Find each edit link
var chks = $('#ContentPlaceHolder1_GVJobList').find('a');
//For each edit link bind click with function
$.each(chks, function () { $(this).on('click', function () {
    // trying to get the calling element
    var $self = $(this);
    // trying to get the parent(cell) then parent(row) then find the checkbox
    alert($($self).parent().parent().find('input:checkbox').val());
}) });

一段時間以來一直是一個問題，因此將不勝感激。 我願意使用任何可以實現這一目標的方法。

<asp:GridView ID="GVJobList" runat="server" AutoGenerateColumns="False" DataSourceID="SDSJobsDetails" OnRowCommand="GV_JobList_RowCommand" DataKeyNames="InvoiceID">

Answer 1

因此，DJ KRAZE的建議沒有足夠的信息對我有用。 但是我發現一個關鍵詞組合，谷歌放棄了部分答案。

protected void chkChanged(object sender, EventArgs e)
{
    GridViewRow row = (GridViewRow) (sender as CheckBox).Parent.Parent;
    CheckBox chk = (sender as CheckBox);
    TextBox comp = row.Cells[11].Controls[0] as TextBox;
    TextBox totalAmt = row.Cells[7].Controls[0] as TextBox;
    TextBox paid = row.Cells[8].Controls[0] as TextBox;
    TextBox datePaid = row.Cells[12].Controls[0] as TextBox;

    if (chk.ID.Equals("CB_Completed") && chk.Checked)
    {
        comp.Text = DateTime.Now.ToString();
    }
    else if (chk.ID.Equals("CB_Completed") && !chk.Checked)
    {
        comp.Text = "";
    }

    if (chk.ID.Equals("CB_PaidInFull") && chk.Checked)
    {
       datePaid.Text = DateTime.Now.ToString();
       paid.Text = totalAmt.Text;
    }
    else if (chk.ID.Equals("CB_PaidInFull") && !chk.Checked)
    {
        datePaid.Text = "";
        paid.Text = "";
    }
}

這意味着有一些到服務器的調用，有時它可能很慢，但是可以完成工作。 也許有一天我會重新審視整個事情，然后嘗試使用javascript或jquery對其進行處理。

基本上，我用模板字段和復選框替換了checkboxfield。 這使我在不處於編輯模式時仍能保持外觀不變，而asp.net可以為我完成啟用工作。 這使我可以比較ID。 然后，我將AutoPostBack與CheckedChange一起使用來檢測帖子之間復選框的更改，這是服務器可以做到的唯一方法（這很有意義）。
