Disabled child checkboxes

[Aniket]

Hi,

 I was wondering if there is a way to disable child check boxes when parent check boxes have been disabled. I have used the selectableMode property to disable parent checkbox but am running into issue disabling child checkbox using same property.

 C#:

//This is for disabling child checkbox

protected void BindChildGrid(GridDataItem parentItem)

        {
            var ucQuoteRows = parentItem.ChildItem.FindControl("ucExpiringRealServices") as UserControls.CustomerGrid;
            CheckBox checkBox = (CheckBox)parentItem["BulkActionSelect"].Controls[0];

            if (ucQuoteRows != null)
            {
                checkBox.Attributes.Add("data-customergridid", ucQuoteRows.ClientID);
                //var envelopeName = parentItem.GetDataKeyValue("Name");
                ucQuoteRows.ParentId = parentItem.GetDataKeyValue("ObjectId").ToString();
                /*ucQuoteRows.ExportFileNamePrefix = envelopeName.ToString();
                ucQuoteRows.TaInfoEnable = RoleEngine.CurrentUserHasTARead();*/
                //BindCustomerGrid(ucQuoteRows, null);
                if (parentItem.SelectableMode == GridItemSelectableMode.None)
                {
                    ucQuoteRows.AllowSelection = false;
                }
                else if (parentItem.SelectableMode == GridItemSelectableMode.ServerAndClientSide)
                {
                    ucQuoteRows.AllowSelection = true;
                }
                ucQuoteRows.ColumnCollection = null;
                ucQuoteRows.Rebind();
            }
        }



//this correctly disables parent checkbox
protected void rgExpiringServices_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {

                var dataItem = ((GridDataItem)e.Item);
                var ObjectId = Guid.Parse(dataItem.GetDataKeyValue("ObjectId").ToString());

                e.Item.SelectableMode = this.DisabledIds.Contains(ObjectId) ? GridItemSelectableMode.None : GridItemSelectableMode.ServerAndClientSide;

            }
        }

Hi,

WIthin the OnItemDataBound event of your nested grid you could get reference to the parent data item and set its SelectableMode to the nested items:

protected void ucExpiringRealServices_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        (e.Item as GridDataItem).SelectableMode = (e.Item.OwnerTableView.OwnerGrid.NamingContainer as GridNestedViewItem).ParentItem.SelectableMode;
    }
}

Hope this helps.

This won't work since it is a custom create user control.

Hello,

For custom user control you could try to get reference to the checkboxes in the NestedViewTemplate with FindControl method and manually disable them.
