Problem editing checkbox ListViewItems by getting new values

Question

User-1072848465 posted

Is it possible to iteriate through ListViewDataItems to save changes to checkboxes in a ListView? My problem is when I modify the checkboxes the new values are not being passed to my code behind.

Here is my ListView ItemTemplate is is being populated by binding a list in code behind

<ItemTemplate>
<asp:CheckBox ID="standardChkBox" runat="server" Checked='<%# Convert.ToBoolean(Eval("Applied")) %>'Text='<%# Eval("Abbreviation") %>' />
</ItemTemplate>

Once the list is displayed on the page I need to have the ability for the user to modify the checkboxes and save them back to the table. I have an OnClick event on a button that calls this

    protected void applyStandardsBtn_Click(object sender, EventArgs e)
    {
        
        foreach (ListViewDataItem item in StandardsListView.Items)
        {
                    bool chkBox = false;
                    CheckBox checkselect = item.FindControl("standardChkBox") as CheckBox;
                    if (checkselect.Checked)
                        chkBox = true;
                    Byte bchkBox = Convert.ToByte(chkBox);

                    Label lblStandardId = item.FindControl("standID_lbl") as Label;
                    int iStandardID = Convert.ToInt32(lblStandardId.Text);

                    using (var context = new CurriculumModelContainer())
                    {
                        AppliedStandard s = context.AppliedStandards
                                .First(i => i.Id == iStandardID);
                        s.applied = bchkBox;
                        context.SaveChanges();

                    }
        }
    }

How can I retrieve the new values on the checkboxes?

Thanks!
