Question

我试图更新我的gridview，我以前在另一个Web表单上做了它，它工作得很好，但是现在当我单击编辑按钮时，它甚至都没有进入编辑模式。我有命令去做可能会影响这种情况的事情吗？

<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="FOLIO" DataSourceID="SqlDataSource1" OnRowEditing="GridView1_RowEditing1" OnRowCancelingEdit="GridView1_RowCancelingEdit1" OnRowUpdating="GridView1_RowUpdating"  OnRowCommand="GridView1_RowCommand">

我的OnRowEditing，OnRowCancelEditing和OnRowUpdating也有代码。

protected void GridView1_RowEditing1(object sender, GridViewEditEventArgs e)
{
    GridView1.EditIndex = e.NewEditIndex;
    GridView1.DataBind();
}
protected void GridView1_RowCancelingEdit1(object sender, GridViewCancelEditEventArgs e)
{
    GridView1.EditIndex = -1;
    GridView1.DataBind();
}

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    using(OracleConnection conn= new OracleConnection("Data Source=RH; User Id=rechum; Password=madrec3v"))
    {
        conn.Open();
        string sqlCom = "UPDATE FOLIOS_HRS_EXTRA SET NO_EMPL_CAPTURO=:NO_EMPL_CAPTURO, FECHA_CAPTURO=:FECHA_CAPTURO, DEPTO=:DEPTO, NO_EMPL_JEFE=:NO_EMPL_JEFE, FECHA_AUT_JEFE=:FECHA_AUT_JEFE, NO_EMPL_SUB=:NO_EMPL_SUB, FECHA_AUT_SUB=:FECHA_AUT_SUB, ESTADO=:ESTADO, NO_EMPL=:NO_EMPL WHERE FOLIO=:FOLIO";
        OracleCommand cmd = new OracleCommand(sqlCom, conn);

        cmd.Parameters.AddWithValue(":NO_EMPL_CAPTURO", (GridView1.Rows[e.RowIndex].FindControl("txtNoEmplCaptG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":FECHA_CAPTURO", (GridView1.Rows[e.RowIndex].FindControl("txtFechaCaptG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":DEPTO", (GridView1.Rows[e.RowIndex].FindControl("txtDeptoG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":NO_EMPL_JEFE", (GridView1.Rows[e.RowIndex].FindControl("txtNoEmplJefeG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":FECHA_AUT_JEFE", (GridView1.Rows[e.RowIndex].FindControl("txtFechaAutJefeG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":NO_EMPL_SUB", (GridView1.Rows[e.RowIndex].FindControl("txtNoEmplSubG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":FECHA_AUT_SUB", (GridView1.Rows[e.RowIndex].FindControl("txtFechaAutSubG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":ESTADO", (GridView1.Rows[e.RowIndex].FindControl("txtEstadoG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":NO_EMPL", (GridView1.Rows[e.RowIndex].FindControl("txtNoEmplG") as TextBox).Text.Trim());
        cmd.Parameters.AddWithValue(":folio", Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Value.ToString()));

        cmd.ExecuteNonQuery();
        GridView1.EditIndex = -1;

    }
}

您应该在调用DataBind（）之前设置数据源

创建一个函数调用BindGridData(GridView grid)，然后调用它。

设置grid.Datasource并在函数中调用grid.Databind（）。

为什么我的gridview不进入编辑模式？
