protected void gvRestore_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
for (int i = 1; i <= 7; i++)
{
LinkButton lt = (LinkButton)e.Row.Cells[i].Controls[0];
lt.Attributes["href"] = "#";
lt.OnClientClick = string.Format(" return sortDataGridView('{0}','{1}')", lt.CommandArgument, "ASC");
}
}
if (e.Row.RowType == DataControlRowType.Pager)
{
e.Row.Visible = false;
}
}
到这一步，思路基本上已经清晰，剩下的事，就是在服务端响应ajax请求了，很简单，直接看代码，要注意是调用GridView的RendControl方法，输出html。
现在可以实现gridview的ajax排序和分页 ，总结一下思路其实很简单，但在实现的时还是走了点弯路，主要时原本想同通过code形式手工实例化一个GridView，但最终还是没有实现，因为我添加了一个模板列。在模板列中添加一个intput type='Radio' 我在code时继承ITemplate，但我确不知怎样实现value='<%#Eval("operatePath") %>'的绑定，这里留下一个问题吧，谁知道，请告诉我。
复制代码 代码如下:
<asp:TemplateField HeaderText="选择">
<ItemTemplate>
<input type="radio" value='<%#Eval("operatePath") %>'/><label for="Radio1">选择</label>
</ItemTemplate>
</asp:TemplateField>
代码
复制代码 代码如下:
static string sortDirection = "ASC";
protected void Page_Load(object sender, EventArgs e)
{
if (hasKeyName("page"))
{
if (!string.IsNullOrEmpty(Request.QueryString["page"].ToString()))
{
this.gvRestore.PageIndex = int.Parse(Request.QueryString["page"].ToString());
ResponseData(this.gvRestore);
}
}
else
if (hasKeyName("sortEx"))
{
string sortEx = Request.QueryString["sortEx"].ToString();
string sortDir = Request.QueryString["sortDir"].ToString();
if (string.Compare(sortDir, sortDirection, true) == 0)
{
this.gvRestore.Sort(sortEx, SortDirection.Ascending);
sortDirection = "DSAC";
}
else
{
this.gvRestore.Sort(sortEx, SortDirection.Descending);
sortDirection = "ASC";
}
ResponseData(this.gvRestore);
}
}
private bool hasKeyName(string key)
{
string[] keys = Request.QueryString.AllKeys;
foreach (string str in keys)
{
if (String.Compare(key, str, true) == 0)
return true;
}
return false;
}
private void ResponseData(GridView gv)
{
gv.DataSourceID = this.SqlDataSource1.ID;
System.Globalization.CultureInfo info = new System.Globalization.CultureInfo("ZH-CN", true);
System.IO.StringWriter sWriter = new System.IO.StringWriter(info);
System.Web.UI.HtmlTextWriter html = new HtmlTextWriter(sWriter);
gv.DataBind();
if (gv != null)
{
gv.RenderControl(html);
}
Response.Write(html.InnerWriter);
Response.Write(GetNav(gv.PageCount));
Response.Flush();
Response.End();
}
public string GetNav(int pagesize)
{
string NavStr = @"<table><tr>";
for (int i = 0; i < pagesize; i++)
{
NavStr = NavStr + @"<td><a href='#'>" + (i + 1).ToString() + @" | " + @"</a></td>";
}
NavStr = NavStr + @"</tr></table>";
return NavStr;
}
public override void VerifyRenderingInServerForm(Control control)
{
//base.VerifyRenderingInServerForm(control);
}
protected void gvRestore_PreRender(object sender, EventArgs e)
{
this.gvRestore.Visible = false;
}
