Question

我有一个有分页的网格视图。在将数据绑定到网格视图后，我将根据下拉列表的选择过滤网格。这导致2页的结果。但是当我点击第2页时，网格刷新了原始结果。这是我的代码：

DataTable dtSyncQueueTransfer = syncStatusBizManager.GetSyncTransferResult(syncRequestId, serverIds, statusIds, txtFileName.Value);
ViewState["SyncResults"] = dtSyncQueueTransfer;
gvSyncQueueList.DataSource = dtSyncQueueTransfer;
gvSyncQueueList.DataBind();

protected void ddlProjectId_SelectedIndexChanged(object sender, EventArgs e)
{
    DataTable dtSyncResults = (DataTable)ViewState["SyncResults"];
    //To display all the sync results when the dropdown selected value is All.
    if (ddlProjectId.SelectedValue.ToString().Equals("All"))
    {
        gvSyncQueueList.DataSource = dtSyncResults;
        gvSyncQueueList.DataBind();
    }
    //To display the sync results when the user selects a projectId from the drop down.
    else
    {
        DataView viewResults = new DataView(dtSyncResults);
        //Filtering sync results based on projectid.
        viewResults.RowFilter = "ProjectId =" + Convert.ToInt32(ddlProjectId.SelectedValue);
        gvSyncQueueList.DataSource = viewResults;
        gvSyncQueueList.DataBind();
    }
}

protected void gvSyncQueueList_OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvSyncQueueList.PageIndex = e.NewPageIndex;
    gvSyncQueueList.DataSource = (DataTable)ViewState["SyncResults"];
    gvSyncQueueList.DataBind();
    string activetab = GetActiveTab();
    ShowTabs(activetab);
}

有人可以为此提供帮助吗？

这是我的问题的解决方案。我们需要在分页时重新过滤结果。在更改网格页面时，我们需要更改代码如下：

QOS_CLASS_DEFAULT

将数据视图结果和绑定值过滤到具有分页的网格
