小编给大家分享一下asp.net如何实现Gridview分页保存选项,相信大部分人都还不怎么了解,因此分享这篇文章给大家参考一下,希望大家阅读完这篇文章后大有收获,下面让我们一起去了解一下吧!

代码如下:


#region //'Revision: 1.00 Created Date: 2013/08/02 Created ID: Una [#1300071]增加多選框
///


/// Session獲取多選框值
///

private void RememberOldValues()
{
ArrayList categoryIDList = new ArrayList();
string index = "";
foreach (GridViewRow row in gridView.Rows)
{
index = (string)gridView.DataKeys[row.RowIndex].Value;
bool result = ((CheckBox)row.FindControl("DeleteThis")).Checked;

// Check in the Session
if (Session["id"] != null)
categoryIDList = (ArrayList)Session["id"];
if (result)
{
if (!categoryIDList.Contains(index))
categoryIDList.Add(index);
}
else
categoryIDList.Remove(index);
}
if (categoryIDList != null && categoryIDList.Count > 0)
Session["id"] = categoryIDList;
}

///


/// Session分頁時之前多選框為true
///

private void RePopulateValues()
{
ArrayList categoryIDList = (ArrayList)Session["id"];
if (categoryIDList != null && categoryIDList.Count > 0)
{
foreach (GridViewRow row in gridView.Rows)
{
string index = (string)gridView.DataKeys[row.RowIndex].Value;
if (categoryIDList.Contains(index))
{
CheckBox myCheckBox = (CheckBox)row.FindControl("DeleteThis");
myCheckBox.Checked = true;
}
}
}
}
#endregion

复制代码 代码如下:


protected void gridView_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
RememberOldValues();
gridView.PageIndex = e.NewPageIndex;
BindData();
RePopulateValues();
}

复制代码 代码如下:


protected void btnSelect_Click(object sender, EventArgs e)
{
string items = "";
ArrayList categoryIDList = new ArrayList();
string index ="";
foreach (GridViewRow row in gridView.Rows)
{
index = (string)gridView.DataKeys[row.RowIndex].Value;
bool result = ((CheckBox)row.FindControl("DeleteThis")).Checked;

// Check in the Session
if (Session["id"] != null)
categoryIDList = (ArrayList)Session["id"];
if (result)
{
if (!categoryIDList.Contains(index))
categoryIDList.Add(index);
}
else
categoryIDList.Remove(index);
}
if (categoryIDList != null && categoryIDList.Count > 0)
for (int i = 0; i < categoryIDList.Count; i++)
{
items += categoryIDList[i] + ",";
}
items = items.Substring(0, items.Length - 1);
ScriptManager.RegisterStartupScript(this, this.GetType(), "", "check('" + items + "');", true);
Session.Remove("id");
}
