Question

目前我使用的是在GridView控件中执行编辑的标准方法。但是这允许我一次只执行一个操作。在我的应用程序中，当一个字段的一个值发生变化时，用户点击“更新”。应该更新行，并且还应该触发一个删除查询。

我尝试使用手动编辑

<asp:GridView ID="GridView1" runat="server" AllowPaging="True" 
               AllowSorting="True" AutoGenerateColumns="False" DataKeyNames="ID" 
               DataSourceID="sdsample1" Visible="False" OnRowEditing="GridView1_OnRowEditing" OnRowUpdated="GridView1_OnRowUpdated">

- 想要获取backnd中当前编辑行的CheckboxField值及其在gridview中的8列

<asp:CheckBoxField   DataField="Goal_Type" HeaderText="Goal_Type" 
                       SortExpression="Goal_Type" />


protected void GridView1_OnRowEditing(object sender, GridViewEditEventArgs e)
{

((CheckBox)GridView1.Rows[GridView1.SelectedIndex].FindControl("Goal_Type"));
CheckBox chk2 = ((CheckBox)GridView1.Rows[GridView1.EditIndex].Cells[7].Controls[0]);
goal_type =Convert.ToString(chk2.Checked);
if(goal_type.Equals("False"))
Goal_flag.Value ="0";
else
Goal_flag.Value = "1";
}

然后一旦我得到checkbox字段的值设置了一些标志变量，我在下面的函数中执行删除操作

protected void GridView1_OnRowUpdated(object sender, GridViewUpdatedEventArgs e)
{

CheckBox chk2 = ((CheckBox)GridView1.Rows[e.AffectedRows].Cells[7].Controls[0]);
Boolean goal_type = chk2.Checked;
if (goal_type == true && Goal_flag.Value.Equals("0"))
{

string connectionString =
WebConfigurationManager.ConnectionStrings["DataCollectionConnectionString"].ConnectionString;
SqlConnection con = new SqlConnection(connectionString);
SqlCommand cmd;
int ID = Convert.ToInt32(((TextBox)GridView1.Rows[e.AffectedRows].FindControl("ID")).Text);
　

cmd =new SqlCommand("Delete from XXX WHERE (ID = " + ID + ") ", con);
　

cmd.CommandType =

CommandType.Text;
con.Open();

　

cmd.ExecuteNonQuery();

con.Close();

}

我在“GridView1_OnRowEditing”函数本身遇到此错误指数超出范围。必须是非负数且小于集合的大小。参数名称：index

如果在GridView中同时操作我的方法是正确的，请告诉我。

将RowEditing事件用于多个更新。正如本issue中所述：

protected void ASPxGridView1_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e) {
    datasource.UpdateCommand = "UPDATE .....";
    datasource.Update(...);

    datasource.UpdateCommand = "UPDATE .....";
    datasource.Update(...);

    datasource.UpdateCommand = "UPDATE .....";
    datasource.Update(...);

    e.Cancel = true;
    ASPxGridView1.CancelEdit();
}

为了找到控件，我建议使用本期中提到的方法： http://www.devexpress.com/Support/Center/p/Q91970.aspx

protected void grd_ReportChartSeries_RowUpdating(object sender, DevExpress.Web.Data.ASPxDataUpdatingEventArgs e) {
    ASPxGridView gridView = sender as ASPxGridView;
    ASPxComboBox combo = gridView.FindEditRowCellTemplateControl(gridView.Columns["Data2"] as GridViewDataColumn, "comboData2") as ASPxComboBox;
    object data2 = combo.Value;

    combo = gridView.FindEditRowCellTemplateControl(gridView.Columns["ID"] as GridViewDataColumn, "comboID") as ASPxComboBox;
    object ID = combo.Value;

    ASPxTextBox textBox = gridView.FindEditRowCellTemplateControl(gridView.Columns["Data1"] as GridViewDataColumn, "txtData1") as ASPxTextBox;
    object data1 = textBox.Value;

    ds = Session["DataSet"] as DataSet;
    DataTable dataTable = ds.Tables[0];
    DataRow row = dataTable.Rows.Find(e.Keys[0]);
    row["ID"] = ID;
    row["Data1"] = data1;
    row["Data2"] = data2;
    gridView.CancelEdit();
    e.Cancel = true;

}

或者您可以通过一个存储过程调用进行更新和删除。
