Objectdatasource更新问题

Question

大家好我正在使用objectdatasource创建更新功能。实际上它工作正常，直到我没有更改UpdateMethod的参数。我有两个参数但它期望三个参数。给我低于错误。

 ObjectDataSource 'ODSConfig' could not find a non-generic method 'UpdatePagedDataSet' that has parameters: CONFIG_VALUE, configKey, configValue.

C＃代码：

protected void ODSConfig_Updating(object sender, ObjectDataSourceMethodEventArgs e)
  {
    TextBox val = (TextBox)GVConfig.Rows[GVConfig.EditIndex].Cells[2].Controls[0];
    Parameter objKeyConfig = new Parameter("configKey", DbType.String, GVConfig.Rows[GVConfig.EditIndex].Cells[1].Text);
    Parameter objKeyValueConfig = new Parameter("configValue", DbType.String, val.Text);
    e.InputParameters["configKey"] = objKeyConfig.DefaultValue;
    e.InputParameters["configValue"] = objKeyValueConfig.DefaultValue;
  }

Answer 1

添加参数后，只需添加ODSConfig.Update();

在此之后，您的代码将如下所示：

protected void ODSConfig_Updating(object sender, ObjectDataSourceMethodEventArgs e)
  {
    TextBox val = (TextBox)GVConfig.Rows[GVConfig.EditIndex].Cells[2].Controls[0];
    Parameter objKeyConfig = new Parameter("configKey", DbType.String, GVConfig.Rows[GVConfig.EditIndex].Cells[1].Text);
    Parameter objKeyValueConfig = new Parameter("configValue", DbType.String, val.Text);
    e.InputParameters["configKey"] = objKeyConfig.DefaultValue;
    e.InputParameters["configValue"] = objKeyValueConfig.DefaultValue;
ODSConfig.Update();
  }
