Perintah RowEditing tidak diaktifkan

Saya memiliki tampilan grid yang menambahkan baris di footertemplate yang berfungsi dengan baik. Saya ingin menambahkan RowEditing dan RowDeleting ke grid. Saya menambahkan metode RowEditing tetapi ketika saya mengklik tombol 'Edit', baris tambah ditampilkan di footer seolah-olah itu adalah perintah "Tambahkan Baris". Ketika saya membuat prototipe kisi, saya memiliki kolom hanya untuk mengedit dan itu adalah bidang perintah. Saat Anda mengklik tombolnya, barisnya akan berubah sehingga semua bidang dapat diedit. Bagaimana saya bisa melakukan itu jika bidang tersebut adalah bidang ItemTemplate?

Ini markup saya:

<asp:GridView ID="MappingGridView" runat="server" AllowSorting="True" AutoGenerateColumns="False" Caption="Enrollment Mapping Information" CaptionAlign="Top"

 </asp:GridView>

Ini kode saya di belakang:

protected void MappingGridView_RowEditing(object sender, GridViewEditEventArgs e)
    {
        MappingGridView.EditIndex = e.NewEditIndex;
        populateEnrollMappingGrid();
    }

Ketika saya mengklik tombol edit, metode RowEditing tidak dipanggil dan baris footer menampilkan tindakan penyisipan.

Bagaimana cara mendapatkan tombol Edit agar baris yang diklik dapat diedit?

INFORMASI TERBARU Page_Load Ini adalah Metode Page_Load:

 protected void Page_Load(object sender, EventArgs e)
    {          
        try
        {
            if (!IsPostBack)
            {
                //Get the Environment Setting to determine the database to access
                txtBoxEnvironment.Text = CurrentEnvironment;
                DAL.setCurrentEnvironment(CurrentEnvironment);

                //Get All Section information from database
                CSectionInfo.getData();

                //Get All Mapping informatio from database
                CEnrollMappingInfo.getData();

                //Populate the Mapping grid
                MappingGridView.DataSource = CEnrollMappingInfo.getInitialData();

                //Populate the Drop Down Section List
                populateDropDownSectionList(CEnrollMappingInfo.SelectedSectionID);

                //Grid must be bound after the Dropdown List is set so the value in the footer can be determined
                MappingGridView.DataBind();

                //Populate the Section grid
                SectionGridView.DataSource = CSectionInfo.getDataUsingSectionID(CEnrollMappingInfo.SelectedSectionID);

                //Get Course information from database
                populateCourseGrid();

                //Populate the Drop Down Course List
                populateDropDownCourseList(CSectionInfo.SelectedCourseID);

                //Grid must be bound after the Dropdown List is set so the value in the footer can be determined
                SectionGridView.DataBind();
            }
        }
        catch (Exception ex)
        {
            logger.ErrorException(ex.Message, ex);
            Response.Redirect("~/Error.aspx");
        }
    }

Terima kasih.

Coba tebak, Anda menyatukan data GridView pada setiap postback.

Anda memiliki Page_Load yang mirip dengan:

protected void Page_Load(object sender, EventArgs e)
{           
    populateEnrollMappingGrid(); // a method where you assign the DataSource and call grid.DataBind()
}

Gunakan properti IsPostBack:

protected void Page_Load(object sender, EventArgs e)
{    
    if(!IsPostBack)       
        populateEnrollMappingGrid();
}

Saya menambahkan metode Page_Load. Saya memiliki 3 grid semuanya. tetapi kisi Pemetaan diisi di (!IsPostBack) - person Gloria Santin; 12.05.2014

Saya tidak mengerti kapan metode MappingGridView_RowEditing TIDAK dipanggil ketika saya mengklik Tombol 'Edit'. Saya telah mengikuti tutorial untuk fungsi ini. Saya memiliki prototipe yang menggunakan CommandField untuk mengedit dan berfungsi dengan baik. Haruskah TemplateField diubah kembali ke CommandField? - person Gloria Santin; 12.05.2014

Saya memperbaiki masalahnya...

Di markup saya, saya mengatur Tombol Edit CausesValidation=true dan ValidationGroup-MappingGrid yang merupakan validasi sisipan di footer. Untuk memperbaikinya, saya menyetel CausesValidation ke false dan menghapus ValidationGroup.

Saya menetapkan nilai-nilai ini di bidang Tombol Perbarui.

Bekerja sekarang!

Terima kasih.
