GridView有多个DataSources？ [英] GridView With Multiple DataSources?
问题描述
我有一个包含选项集的下拉列表。如果用户选择一个选项，则网格视图将根据该选项显示数据。如果用户选择另一个选项，那么我想在不替换旧数据的情况下将该数据显示在同一网格视图中。
下拉列表事件代码
protected void ddlOptions_SelectedIndexChanged（object sender，EventArgs e）
{
List< OptionsObj> oOptionDetailsList = OptionsDataManager.GetOptionWiseOperationDtls（int.Parse（ddlOptions.SelectedValue.ToString（）））;
OptionDetailsList = oOptionDetailsList;
dgvOptions。 DataSource = OptionDetailsList;
dgvOptions.DataBind（）;
}
请帮我这样做。

推荐答案
List< OptionsObj> oOptionDetailsList = OptionsDataManager.GetOptionWiseOperationDtls（int.Parse（ddlOptions.SelectedValue.ToString（）））;
if（OptionDetailsList == null）
{
OptionDetailsList = oOptionDetailsList;
}
else
{
var isExists =来自OptionDetailsList中的de
其中de.PartId == int.Parse（ddlOptions.SelectedValue.ToString（））
select de ;
if（isExists.Count（）> 0）
{
lblList0.Text =" Process Allready Exists";
}
else
{
OptionDetailsList.AddRange（oOptionDetailsList）;
}
}
List<OptionsObj> oOptionDetailsList = OptionsDataManager.GetOptionWiseOperationDtls(int.Parse(ddlOptions.SelectedValue.ToString()));
if (OptionDetailsList == null)
{
OptionDetailsList = oOptionDetailsList;
}
else
{
var isExists = from de in OptionDetailsList
where de.PartId == int.Parse(ddlOptions.SelectedValue.ToString())
select de;
if (isExists.Count() > 0)
{
lblList0.Text = "Process Allready Exists";
}
else
{
OptionDetailsList.AddRange(oOptionDetailsList);
}
}
