【问题描述】：
我已经创建了带有分页的gridview 并在gridview 中搜索了一个数据。如果你在gridview 中过滤数据，它会成功显示带有分页的结果，我有数据数量和页面数量。显示后，我将单击下一页，因为 gridview 每页仅显示 10 条记录，但我有超过 10 条已过滤的记录，因此它将按页面显示。然后，当我单击下一页时，gridview 将从数据库中加载整个数据并显示，但我希望在搜索数据时仅显示过滤记录。 aspx 代码如下
<asp:Button ID="Search" Text="Search" runat="server" CssClass="searchbtn" OnClick="Search_Click" />
<asp:GridView ID="gvEdit" runat="server" AutoGenerateColumns="False" DataKeyNames="slno" OnRowCreated="gvEdit_RowCreated" OnPageIndexChanging="gvEdit_PageIndexChanging" Width="100%" AllowPaging="True" PageSize="10" OnRowCommand="gvEdit_RowCommand">

下面是 aspx.cs 代码
protected void Search_Click(object sender, EventArgs e)
{
this.BindGrid();
}
private void BindGrid()
{
try
{
if (txtsearch.Text != "")
{
if (ViewState["data"] != null)
{
DataTable dt = (DataTable)ViewState["data"];
DataView dv = new DataView(dt);
dv.RowFilter = "ref_no Like '%" + txtsearch.Text + "%' OR fum Like '%" + txtsearch.Text + "%' OR filing_type Like '%" + txtsearch.Text + "%'OR business_name Like '%" + txtsearch.Text + "%'OR filing_status Like '%" + txtsearch.Text + "%'";
ViewState["filter"] = dv;
gvEdit.DataSource = dv;
gvEdit.DataBind();
//gvformlist.DataSource = dv;
//gvformlist.DataBind();
}
}
}
catch (Exception ex)
{
string a = ex.Message;
}
}
protected void Reset_Click(object sender, EventArgs e)
{
txtsearch.Text = "";
gvEdit.DataSource = ViewState["data"];
gvEdit.DataBind();
//gvformlist.DataSource = ViewState["data"];
//gvformlist.DataBind();
}
protected void gvformlist_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
//gvEdit.PageIndex = e.NewPageIndex;
//gvformlist.PageIndex = e.NewPageIndex;
LoadFormList();
}
protected void gvformlist_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow pagerRow = gvEdit.TopPagerRow;
Label pageLabel = (Label)pagerRow.Cells[0].FindControl("CurrentPageLabel");
if (e.Row.RowType == DataControlRowType.Pager)
{
pageLabel.Text = "Page " + (gvEdit.PageIndex + 1) + " of " + gvEdit.PageCount;
}
}
protected void gvEdit_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvEdit.PageIndex = e.NewPageIndex;
LoadFormList();
}
public void SetPagerButtonStates(GridView gridView, GridViewRow gvPagerRow, Page page, string DDlPager)
{
// to Get No of pages and Page Navigation
int pageIndex = gridView.PageIndex;
int pageCount = gridView.PageCount;
ImageButton btnFirst = (ImageButton)gvPagerRow.FindControl("ImgeBtnFirst");
ImageButton btnPrevious = (ImageButton)gvPagerRow.FindControl("ImgbtnPrevious");
ImageButton btnNext = (ImageButton)gvPagerRow.FindControl("ImgbtnNext");
ImageButton btnLast = (ImageButton)gvPagerRow.FindControl("ImgbtnLast");
btnFirst.Enabled = btnPrevious.Enabled = (pageIndex != 0);
btnNext.Enabled = btnLast.Enabled = (pageIndex < (pageCount - 1));
DropDownList ddlPageSelector = (DropDownList)gvPagerRow.FindControl(DDlPager);
ddlPageSelector.Items.Clear();
for (int i = 1; i <= gridView.PageCount; i++)
{
ddlPageSelector.Items.Add(i.ToString());
}
ddlPageSelector.SelectedIndex = pageIndex;
string strPgeIndx = Convert.ToString(gridView.PageIndex + 1) + " of "
+ gridView.PageCount.ToString();
Label lblpageindx = (Label)gvPagerRow.FindControl("lblpageindx");
lblpageindx.Text += strPgeIndx;
}
protected void ddlPageSelector_SelectedIndexChanged(object sender, EventArgs e)
{
gvEdit.PageIndex = ((DropDownList)sender).SelectedIndex;
LoadFormList();
}
protected void gvEdit_RowCreated(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Pager)
{
SetPagerButtonStates(gvEdit, e.Row, this, "ddlPageSelector");
}
}
protected void gvEdit_RowCommand(object sender, GridViewCommandEventArgs e)
{
}
我已根据某人的建议更改了 gvEdit_PageIndexChanging 中的代码
protected void gvEdit_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
try
{
if (ViewState["filter"] != null)
{
gvEdit.PageIndex = e.NewPageIndex;
gvEdit.DataSource = ViewState["filter"];
gvEdit.DataBind();
}
else
{
gvEdit.PageIndex = e.NewPageIndex;
LoadFormList();
}
}
catch (Exception ex)
{
string a = ex.Message;
}
}
之后我运行代码，我得到了错误 错误是 System.Runtime.Serialization.SerializationException: Type 'System.Data.DataView' in Assembly 'System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' 未标记为可序列化。强>
【问题讨论】：
-
为什么不使用Jquery Datatables？它们具有丰富的定制功能。
-
我需要没有 jquery ............如果有任何解决方案请帮助我
-
你被文本框过滤了吗？
-
是的....我在文本框的帮助下搜索数据
-
我发布了一个答案。看看它。我希望它是你想要的答案。
