我创建了一个分页网格视图，其中包含多个选择的复选框。但是在网格视图中循环遍历数据行时，只有最后一页的行值才能得到。我知道这是因为分页
我的代码在
下面 protected void btnSaveItemMapping_Click(object sender, EventArgs e)
{
grdCustomers.AllowPaging = false;
foreach (GridViewRow gvrow in grdCustomers.Rows)
{
CheckBox myCheckBox = (CheckBox)gvrow.FindControl("chkBoxBrandCustomers");
if (myCheckBox.Checked == true)
{
Label lblCustomerCode = (Label)gvrow.FindControl("lblCustomerCode");
//INSERT TO DATABSE
}
}
grdCustomers.AllowPaging = true
}
在更改页面索引后保持选中复选框，如下面的代码。
protected void grdCustomers_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
savechkdvls_cst();
grdCustomers.PageIndex = e.NewPageIndex;
if (Session["AllCustomers"] != null)
{
lstAllCustomers = (List<CustomerMaster>)Session["AllCustomers"];
}
grdCustomers.DataSource = lstAllCustomers;
grdCustomers.DataBind();
chkdvaluesp_cst();
}
private void chkdvaluesp_cst()
{
ArrayList usercontent = (ArrayList)Session["chkditems_customers"];
if (usercontent != null && usercontent.Count > 0)
{
foreach (GridViewRow gvrow in grdCustomers.Rows)
{
int index = Convert.ToInt32(grdCustomers.DataKeys[gvrow.RowIndex].Value);
if (usercontent.Contains(index))
{
CheckBox myCheckBox = (CheckBox)gvrow.FindControl("chkBoxBrandCustomers");
myCheckBox.Checked = true;
}
}
}
}
private void savechkdvls_cst()
{
ArrayList usercontent = new ArrayList();
int index = -1;
foreach (GridViewRow gvrow in grdCustomers.Rows)
{
index = Convert.ToInt32(grdCustomers.DataKeys[gvrow.RowIndex].Value);
bool result = ((CheckBox)gvrow.FindControl("chkBoxBrandCustomers")).Checked;
// Check in the Session
if (Session["chkditems_customers"] != null)
usercontent = (ArrayList)Session["chkditems_customers"];
if (result)
{
if (!usercontent.Contains(index))
usercontent.Add(index);
}
else
usercontent.Remove(index);
}
if (usercontent != null && usercontent.Count > 0)
Session["chkditems_customers"] = usercontent;
}
任何帮助将不胜感激。
