Error in Filter in MultiColumnComboBox

[mohammad]

When I use the tree as MultiColumnComboBox
 The table has a relation with itself
When I click on MultiColumnComboBox the popup
  The following error occurs

radMultiColumnComboBox1.MultiColumnComboBoxElement.EditorControl.Relations.AddSelfReference(this.radMultiColumnComboBox1.MultiColumnComboBoxElement.EditorControl.MasterTemplate, "id", "parentid");
            sqlDataAdapter1.Fill(dataSet11);
            radMultiColumnComboBox1.DataSource = t1BindingSource;
            radMultiColumnComboBox1.DisplayMember = "name";
            radMultiColumnComboBox1.ValueMember = "id";




            this.radMultiColumnComboBox1.AutoFilter = true;
            this.radMultiColumnComboBox1.DisplayMember = "name";
            FilterDescriptor filter = new FilterDescriptor();
            filter.PropertyName = this.radMultiColumnComboBox1.DisplayMember;
            filter.Operator = FilterOperator.Contains;
            this.radMultiColumnComboBox1.EditorControl.MasterTemplate.FilterDescriptors.Add(filter);

sql create table
relation in id and parentid

CREATE TABLE [dbo].[T1](
    [id] [int] NOT NULL,
    [name] [nvarchar](50) COLLATE Arabic_CI_AS NULL,
    [parentid] [int] NULL,
 CONSTRAINT [PK_T1] PRIMARY KEY CLUSTERED
(
    [id] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
ALTER TABLE [dbo].[T1]  WITH CHECK ADD  CONSTRAINT [FK_T1_T1] FOREIGN KEY([parentid])

Hi Svett, i have the same error when i upgrade our radcontrol winform 2011 to 2013. All multicolumncombobox with Self Reference has error.

Thanks in advance.

comboBox.AutoFilter = true;

FilterDescriptor filter = new FilterDescriptor();
filter.PropertyName = comboBox.DisplayMember;
filter.Operator = FilterOperator.Contains;
comboBox.EditorControl.MasterTemplate.FilterDescriptors.Add(filter);

comboBox.EditorControl.MasterTemplate.Columns["EquipStructNodeID"].IsVisible = false;
comboBox.EditorControl.MasterTemplate.Columns["Display"].IsVisible = false;
comboBox.EditorControl.MasterTemplate.Columns["ParentEquipStructNodeID"].IsVisible = false;

if (comboBox.EditorControl.RowCount > 0)
{
      comboBox.EditorControl.Relations.AddSelfReference(comboBox.EditorControl.MasterTemplate, "EquipStructNodeID", "ParentEquipStructNodeID");
      comboBox.EditorControl.TableElement.ShowSelfReferenceLines = true;
      comboBox.EditorControl.MasterTemplate.ExpandAll();
}

Hello Daniel,

Thank you for contacting us.

I was able to reproduce the issue you are describing. I appears to exist only when the RadMultiColumnComboBox's EditorControl is in SelfReferenceMode. I have logged it in our Public Issue Tracking System. You can find it on the following URL - http://www.telerik.com/support/pits.aspx#/public/winforms/15899. Unfortunately I cannot provide you with a workaround due to the nature of the issue.

I have updated your Telerik Points for your report.

Let me know if I can be of further assistance.

Regards,
George
