When I was using a GridClientSelectColumn to select rows in my RadGrid, I used this post and this post to persist the checked state on the client side, using JavaScript to store the selected row ids in a hidden field.

I'd like to do this with checkboxes that are GridTemplateColumns defined on the server side, like this:

    foreach (blah blah)
    {
        templateColumn = new GridTemplateColumn();
        RadGrid1.MasterTableView.Columns.Add(templateColumn);
        templateColumn.ItemTemplate = new MyTemplate(blah);
        templateColumn.HeaderText = blah;
    }
 
private class MyTemplate : ITemplate
{
    protected CheckBox chk;
    private string columnName;
 
    public MyTemplate(string columnName)
    {
        this.columnName = columnName;
    }
 
    public void InstantiateIn(Control container)
    {
        chk = new CheckBox();
        chk.ID = "chk" + columnName;
        chk.DataBinding += new EventHandler(DataBinding);
        chk.Enabled = true;
        container.Controls.Add(chk);
    }
 
    void DataBinding(object sender, EventArgs e)
    {
        CheckBox cBox = (CheckBox)sender;
        GridDataItem container = (GridDataItem)cBox.NamingContainer;
        cBox.Checked = (bool)((DataRowView)container.DataItem)[columnName];
    }
}

I think I can do the same kind of thing here, except I can no longer call the JavaScript function RadGrid1_RowSelected since I'm not selecting the row, just checking boxes. I'll need to use another event that fires when a checkbox is checked or unchecked (I guess that's CheckChanged). But how do I add a handler on the server side and have it handled on the client side?
