Hey guys,

Not sure if this is a bug or if I'm just doing something wrong.

I'm using a multiColumnComboBox with AutoFilter set to true.

Open the drop-down box (optional, see 3)
Type some text into the box.
Open the drop-down box (optiona, either 1 or 3 is same)
Select an entry with mouse or keyboard - same effect
Try to type new text into the box.

After step 5, my box is looking up for each individual character I type, and selecting the first entry on each return..

After step 5, if I open the box first and then type, the box will select and close after I hit a single character.

After step 5, if I hit the semicolon, no character will appear in the box - but the fiddly behaviour goes back to normal.

Not sure if this is to do with my code or not. Here's the section where I bind to the multiColumn:

                                        internal void FillDropDowns(bool bRefill)         
                                {         
                                    string sSuburbText = this.mcboSuburb.Text;         
                                    // string sTownText = this.cboTown.Text;         
                                 
                                    if (bRefill)         
                                    {         
                                        this.LocationsSentTo.Clear();         
                                        this.LocationsSentToTableAdapter.Fill(this.DataSet, "LocationsSentTo");         
                                    }         
                                 
                                    this.mcboSuburb.DataSource = this.LocationsSentTo; // This is a wrapper property around the DataSet table referred to above.         
                                    this.mcboSuburb.DisplayMember = "postCode_prefix";         
                                    this.mcboSuburb.ValueMember = "postCode";         
                                 
                                    RadGridView gridView = this.mcboSuburb.MultiColumnComboBoxElement.EditorControl;         
                                 
                                    GridViewDataColumn prefixColumn = gridView.Columns["postCode_prefix"];         
                                    prefixColumn.HeaderText = "Suburb";         
                                    prefixColumn.Index = 0;         
                                    prefixColumn.BestFit();         
                                 
                                    GridViewDataColumn postCodeColumn = gridView.Columns["postCode"];         
                                    postCodeColumn.HeaderText = "PostCode";         
                                    postCodeColumn.Index = 1;         
                                    postCodeColumn.BestFit();         
                                 
                                    GridViewDataColumn sentToColumn = gridView.Columns["sentTo"];         
                                    sentToColumn.HeaderText = "SentTo (D)";         
                                    sentToColumn.Index = 2;

                                    sentToColumn.BestFit();         
                                 
                                    GridViewDataColumn siteIdColumn = gridView.Columns["siteId_fk"];         
                                    siteIdColumn.HeaderText = "Site ID (D)";         
                                    siteIdColumn.Index = 3;         
                                    siteIdColumn.IsVisible = Program.DebugMode;         
                                    siteIdColumn.BestFit();         
                                 
                                    if (this.mcboSuburb.EditorControl.MasterGridViewTemplate.FilterExpressions[this.mcboSuburb.DisplayMember] == null)         
                                    {         
                                        FilterExpression filter = new FilterExpression(         
                                            this.mcboSuburb.DisplayMember, FilterExpression.BinaryOperation.AND,         
                                            GridKnownFunction.Contains, GridFilterCellElement.ParameterName);         
                                 
                                        filter.Parameters.Add(GridFilterCellElement.ParameterName, true);         
                                 
                                        this.mcboSuburb.EditorControl.MasterGridViewTemplate.FilterExpressions.Add(filter);         
                                    }         
                                 
                                    this.mcboSuburb.SelectedItem = null;         
                                    this.mcboSuburb.Text = sSuburbText;         
                                }         

Note that the FillDropDowns is not being called by any events while the typing or opening is taking place.

Hi Cameron,

Thanks for writing and for reporting this issue. I managed to reproduce the case and indeed, this is an issue in the RadMultiColumnComboBox control. Unfortunately I was not able to find a workaround for you, however, we are going to investigate this further and provide a fix for our next major release. I have updated your Telerik points for bringing our attention to this issue, as well.

Do not hesitate to write back if you need further assistance.

Sincerely yours,
Deyan
