Check ListBox items on DataBound

[Jordan]

Hello,

 I am using a "Combined" filter type on a RadGrid and some of my columns use the CheckList filter like the one shown below. 

<telerik:GridBoundColumn
    DataField="State" HeaderText="State" ReadOnly="true" HeaderStyle-Width="40px" FilterControlWidth="40px"
    ItemStyle-Width="40px" AutoPostBackOnFilter="true" UniqueName="State" SortExpression="State"
    FilterCheckListEnableLoadOnDemand="false" FilterControlAltText="Filter State column" CurrentFilterFunction="StartsWith"/>

We are using a persistence manager to restore the state of the grid, sometimes this includes values that were checked in the column above. When restoring from the persistence manager, the grid is filtered correctly however, the values are not checked in the FilterCheckList.

 I tried checking the values in the DataBound event handler for the list box and the values get selected correctly but not checked correctly.

private void ListBox_DataBound(object sender, EventArgs e)
{
    RadListBox listBox = sender as RadListBox;
    string filter = grdOpportunities.MasterTableView.FilterExpression;
    filter = filter.Replace("AND", "&");
    string[] filters = filter.Split('&');

    foreach (string f in filters)
    {
        if (f.Contains(listBox.DataKeyField))
        {
            string current = f.Replace("OR", "&");
            string[] options = current.Split('&');

            foreach (string o in options)
            {
                foreach (RadListBoxItem item in listBox.Items)
                {
                    if (o.Contains(item.DataKey.ToString()))
                    {
                        item.Selected = true;
                        item.Checked = true;
                    }
                }
            }
        }
    }
}

Attached is what I see after this code block is executed. 

Please advise, thank you!

Hello Jordan,

Could you please send me a runnable sample where I could observe the problem?

Peter,

 Here is a link to a runnable demo: https://drive.google.com/file/d/0B_is1WIRqr-jTWF4d0dvYUx0aGM/view?usp=sharing

With this demo you are able to filter the grid by check box, save the state, and restore the state. When restoring, the check boxes are no longer checked.

Thanks,

Jordan

I submitted a support ticket for this as well.

Persistence Framework does not support persistence of the checkbox filter state at this time.
