GridViewMultiComboBoxColumn dropdown closed

[james]

Dear all 

I have a question 

how do all this syntax in GVMCCB ? 

    Private Sub CMMBCustomer_CustomFiltering(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCustomFilteringEventArgs)

        Dim element As RadMultiColumnComboBoxElement = MCCBCustomer.MultiColumnComboBoxElement

        Dim textToSearch As String = MCCBCustomer.Text
        If AutoCompleteMode.Append = (element.AutoCompleteMode And AutoCompleteMode.Append) Then
            If element.SelectionLength > 0 AndAlso element.SelectionStart > 0 Then
                textToSearch = MCCBCustomer.Text.Substring(0, element.SelectionStart)
            End If
        End If

        If String.IsNullOrEmpty(textToSearch) Then
            e.Visible = True

            For i As Integer = 0 To element.EditorControl.ColumnCount - 1
                e.Row.Cells(i).Style.Reset()

            Next

            e.Row.InvalidateRow()
            Return
        End If

        e.Visible = False
        For i As Integer = 0 To element.EditorControl.ColumnCount - 1
            Dim text As String = e.Row.Cells(i).Value.ToString()
            If text.IndexOf(textToSearch, 0, StringComparison.InvariantCultureIgnoreCase) >= 0 Then
                e.Visible = True
                e.Row.Cells(i).Style.CustomizeFill = True
                e.Row.Cells(i).Style.DrawFill = True
                e.Row.Cells(i).Style.BackColor = Color.FromArgb(201, 252, 254)
            Else
                e.Row.Cells(i).Style.Reset()

            End If
        Next
        e.Row.InvalidateRow()
    End Sub
    Private Sub CMMBCustomer_KeyDown(ByVal sender As Object, ByVal e As KeyEventArgs)
        With MCCBCustomer
            If e.KeyCode = System.Windows.Forms.Keys.Enter Then
                If .ValueMember <> "" Then
                    .SelectedValue = .EditorControl.CurrentRow.Cells(.ValueMember).Value

Hello James,

Thank you for writing.  

Note that you can handle the RadGridView.CellEditorInitialized event which is fired once the editor is initialized. This is the place where you have access to the RadMultiColumnComboBoxElement and you can subscribe to any of the desired events that you want to use:

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.ProductsTableAdapter.Fill(Me.NwindDataSet.Products)
    Me.CategoriesTableAdapter.Fill(Me.NwindDataSet.Categories)

    Me.RadGridView1.DataSource = ProductsBindingSource

    Dim col As GridViewMultiComboBoxColumn = New GridViewMultiComboBoxColumn("Category")
    col.DataSource = Me.CategoriesBindingSource
    col.DisplayMember = "CategoryName"
    col.ValueMember = "CategoryID"
    col.FieldName = "CategoryID"
    Me.RadGridView1.Columns.Add(col)

    AddHandler Me.RadGridView1.CellEditorInitialized, AddressOf CellEditorInitialized
End Sub

Private Sub CellEditorInitialized(sender As Object, e As GridViewCellEventArgs)
    Dim mccb As RadMultiColumnComboBoxElement = TryCast(e.ActiveEditor, RadMultiColumnComboBoxElement)
    If mccb IsNot Nothing Then
        RemoveHandler  mccb.KeyDown, AddressOf mccb_KeyDown
        AddHandler mccb.KeyDown, AddressOf mccb_KeyDown
    End If

End Sub

Private Sub mccb_KeyDown(sender As Object, e As KeyEventArgs)
    Console.WriteLine(e.KeyData)
End Sub

I hope this information helps. Should you have further questions I would be glad to help.

Hello Dess 

Thanks for fast respone... i will try it first ...

thanks You very much

 

[james]

Hello Dess 

i need to fill the field "NAMA" inside the gridview from mccb.dropdown how make this happen ? 

i need to filtering too when user type in mccb gridview 

Thanks before

 

Note : please give me the very simple code... 

[Dess | Tech Support Engineer, Principal]

Hello James, 

Thank you for writing back. 

In order to populate the RadMultiColumnComboBoxElement in the GridViewMultiComboBoxColumn with data, you can set the GridViewMultiComboBoxColumn.DataSource property to the desired collection. Additional information how to setup the columns is available here: http://docs.telerik.com/devtools/winforms/gridview/columns/column-types/gridviewmulticomboboxcolumn

After making a selection in the editor, you can set the value for another cell on the same row. Here is a sample code snippet which result is illustrated in the attached gif file: 

Me.RadGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill

Private Sub ValueChanged(sender As Object, e As EventArgs)
    Dim mccb As RadMultiColumnComboBoxElement = TryCast(Me.RadGridView1.ActiveEditor, RadMultiColumnComboBoxElement)
    If mccb IsNot Nothing Then
        Dim rowInfo As GridViewDataRowInfo = TryCast(mccb.SelectedItem, GridViewDataRowInfo)
        Me.RadGridView1.CurrentRow.Cells("CategoryID").Value = rowInfo.Cells("CategoryID").Value
    End If
End Sub

As to the filtering functionality, you can refer to the following example. Thus, when typing in the editor, the popup grid is filtered: 

AddHandler Me.RadGridView1.CellEditorInitialized, AddressOf CellEditorInitialized

Private Sub CellEditorInitialized(sender As Object, e As GridViewCellEventArgs)
    Dim mccb As RadMultiColumnComboBoxElement = TryCast(e.ActiveEditor, RadMultiColumnComboBoxElement)
    If mccb IsNot Nothing Then
        mccb.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown
        mccb.AutoFilter = True
        If mccb.EditorControl.FilterDescriptors.Count = 0 Then
            Dim filter As New FilterDescriptor()
            filter.PropertyName = mccb.DisplayMember
            filter.Operator = FilterOperator.Contains
            mccb.EditorControl.MasterTemplate.FilterDescriptors.Add(filter)
        End If
    End If
End Sub

I hope this information helps. If you have any additional questions, please let me know.

Hello dess... ?

i've tried the code you wrote why it doesn't work for me ? 

Private Sub ValueChanged(sender As Object, e As EventArgs)
    Dim mccb As RadMultiColumnComboBoxElement = TryCast(Me.RadGridView1.ActiveEditor, RadMultiColumnComboBoxElement)
    If mccb IsNot Nothing Then
        Dim rowInfo As GridViewDataRowInfo = TryCast(mccb.SelectedItem, GridViewDataRowInfo)
        Me.RadGridView1.CurrentRow.Cells("CategoryID").Value = rowInfo.Cells("CategoryID").Value
    End If
End Sub

 

how to call this sub ? 

 

Thanks before

Hai Dess 

or how access dropdownclosed in gridviewmulticolumncombobox....

"Me.RadGridView1.CurrentRow.Cells("CategoryID").Value = rowInfo.Cells("CategoryID").Value" i need this code run when dropdwonclosed

Thanks

 

[Dess | Tech Support Engineer, Principal]

Hello, Hengky, 

Thank you for writing.  

The ValueChanged event in RadGridView is fired when you change the value in the editor. RadMultiColumnComboBoxElement automatically closed its popup when a row is selected in the inner grid. Then, the ValueChanged event will be fired and the value of the neighboring cell will be updated accordingly.

I hope this information helps. Should you have further questions I would be glad to help.

Hai Dess thanks for writing back 

how if i need to change the category id, not the category name.

your example is change the categoryname, what i need is change the CategoryId on Product table

 

thanks before 

* i will mentioned about licensing.

[Dess | Tech Support Engineer, Principal]

Hello, Hengky, 

Thank you for writing back. 

It is up to you for which field you will add the GridViewMultiComboBoxColumn. It is necessary to specify the column's FieldName property (e.g. "CategoryID") and populate it with data (by the DataSource property). Then, in the RadGridView.ValueChanged event you can manipulate each cell value according to your custom requirement.  

I hope this information helps. If you have any additional questions, please let me know.

Hello Dess,

thanks for the solution and now it works,

but i have problem... like the attachment pic.

it's error when i hit enter on column 3,4 

column 5 is expression on column 3 and 4

 

Thanks

[Dess | Tech Support Engineer, Principal]

Hello, Hengky, 

Thank you for writing back. 

I was not able to replicate the issue with my sample project. However, according to the error message, I suppose that you have only constructors with parameters in your custom object. In this case, the parameterless constructor is required by our implementation in RadGridView to create a new instance of the class and populate the data according to the data in the columns. So in order to be able to add new rows you need to add a parameterless constructor as well. 

If it is not the case, feel free to submit a support ticket where you can provide a sample project demonstrating the undesired behavior. Thus, our support staff will gladly assist you.

I hope this information helps.

Hai dess... sorry for late reply.... 

how to make this happen if i use Entity Framework for fill the col ... 

            For Each s In query_detail
                RadGridView1.Rows.Add(s.Kode, s.NamaBarang, s.Qtty, s.Harga, s.Nilai)
            Next

            Dim col As GridViewMultiComboBoxColumn = New GridViewMultiComboBoxColumn("KodeBarang")
            Dim SqlBarang = From Barang In db.MstBarangs
                            Select New With {Barang.KodeBarang, Barang.NamaBarang}

            col.DataSource = SqlBarang.ToList

            col.DisplayMember = "NamaBarang"
            col.ValueMember = "KodeBarang"
            col.MinWidth = 100
            col.FieldName = "KodeBarang"
            Me.RadGridView1.Columns.Add(col)

the code working fine, but with one miss ... it doesn't want to show the NamaBarang for the first time

Hi Hengky,

You can check the following resources discussing in details how you can bind the grid using Entity Framework:

• https://docs.telerik.com/devtools/winforms/gridview/populating-with-data/binding-to-entityframework-using-database-first-approach
• https://www.telerik.com/support/kb/winforms/gridview/details/binding-radgridview-to-entity-framework-using-code-first-approach

From your code snippet, it appears that you are doing a select which returns anonymous types. Please avoid this as the grid would not be editable. This behavior can also be observed with the standard .NET grid control. The following articles provide more information on that matter: 

• https://blogs.msdn.microsoft.com/swiss_dpe_team/2008/01/25/using-your-own-defined-type-in-a-linq-query-expression/
• https://stackoverflow.com/questions/3474531/linq-and-how-to-return-a-list-of-a-specific-type

I hope this information was useful.

Hello Hristo, thanks for writing back... 

i already bind the grid from EF. the blank column on the picture is MultiColumnComboBox... that fill with data to like example from Dess. ( if i use ado.net binding, its very well working) 

How make this happen with EF.. ?

 

 

 

[Hristo]

Hi Hengky,

Binding the GridViewMultiComboBoxColumn to Entity Framework should not be much different compared to the grid. As demonstrated in the grid`s article please make sure that you load the collection in the DbContext and then access it through the Local property like this: 

col.DataSource = dbContext.Orders.Local.ToBindingList();

 
As I said before, please also make sure that you do not bind to a collection of anonymous types. In case you need further assistance, please open a support ticket and send us your project so that we can investigate it locally.

Let me know if you have other questions.

Hristo

Hello, Hengky,

According to the provided code snippet, it seems that you are extracting the data from a database. I suspect that this takes most of the time. It would be good to detect how much time the DataSet population takes.

I have created a project with a GridViewMultiComboBoxColumn bound to Northwind.Categories table. It is bound immediately on my end. I have attached my sample project. Could you please specify the exact steps how to reproduce the problem with it?

Feel free to submit a support ticket from your Telerik account where you can provide a sample project demonstrating the performance problem that you are facing. Thus, we would be able to make an adequate analysis of the precise case and provide further assistance. Thank you in advance. 

I am looking forward to your reply.

Hai dess 

I have created the project from the example that u gave to me long years ago ... 

i have still facing the same problem .... because of this I tried the other product ... hehehehe....

it's have faster performance then telerik ... with the same code ... but telerik have more friendly in GUI development ... 

actually i just need to make in line add data with gridview ... 

 

Hope u understand what i mean ...

[Dess | Tech Support Engineer, Principal]

Hi, Hengky,

Without replicating the issue locally, we can make only conjectures what causes the undesired slow loading on your end. Have you tried to run my sample project? Is it loaded as expected on your end? I would suggest you to detect how much time the DataSet population takes on your end. How many record do you have in the DataSet?

Would it be possible to submit a support ticket from your Telerik account and provide a runnable sample project demonstrating the undesired behavior that you are facing? If it would be easier for you, feel free to modify the previously provided sample project.

Once we replicate the issue locally, we would be able to investigate the precise case and think about a suitable solution.

An alternative solution that is worth considering is using a RadPopupEditor and hosting either RadGridView in the popup container or a RadVirtualGrid.

The following example demonstrates how to get started with the RadPopupEditor and host the desired controls in the container: https://docs.telerik.com/devtools/winforms/controls/editors/popupeditor/getting-started 

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

on "OK" click it will return the value of column 1 & 2 in FrmCari 

what i get is, always error if the row blank .... (or new state)

[Dess | Tech Support Engineer, Principal]

Hello, Hengky,

Following the provided code snippet, I have updated my sample project. It seems that you are using the filtering functionality in the GridViewMultiComboBoxColumn. Indeed, with 9000 rows in the RadMultiColumnComboBoxElement editor, there is a slight delay because the filtering is performed on each key stroke and there are a lot of records to iterate and find the matches. 

Since R2 2017 version, you can improve the user experience with cursor lagging while filtering in the editor. In the CellEditorInitialized event you can set the RadMultiColumnComboBoxElement.AutoFilterDelay property to 1000 for example. Thus, you can specify the value in milliseconds indicating delay between last key press and filtering operation. 

    Private Sub CellEditorInitialized(sender As Object, e As GridViewCellEventArgs)
        Dim mccb As RadMultiColumnComboBoxElement = TryCast(e.ActiveEditor, RadMultiColumnComboBoxElement)
        If mccb IsNot Nothing Then
            mccb.DropDownStyle = Telerik.WinControls.RadDropDownStyle.DropDown
            mccb.AutoFilter = True
            If mccb.EditorControl.FilterDescriptors.Count = 0 Then
                Dim filter As New FilterDescriptor()
                filter.PropertyName = mccb.DisplayMember
                filter.Operator = FilterOperator.Contains
                mccb.EditorControl.MasterTemplate.FilterDescriptors.Add(filter)
                mccb.AutoFilterDelay = 1000
            End If
        End If
    End Sub

I hope this information helps. If you need any further assistance please don't hesitate to contact me.

Hai dess i have tried the code you give to me. 

but the performance not increase so much .... 

because of this, i use to call the commandcell to open the searching form ... and return to the source form ... it's better performace..

and the problem .... how to call this : 

    Private Sub GridDetail_CommandCellClick(sender As Object, e As GridViewCellEventArgs) Handles GridDetail.CommandCellClick
        baris = GridDetail.CurrentRow.Index

        ParamForm = "TrTerimaBarangEntri"
        Dim frm As New FrmCari

        Select Case e.Column.Name
            Case "BtnCariBarangGrid"
                frm.Text = "BarangGrid"
        End Select
        SettingFrmCari(frm)
        frm.ShowDialog()

    End Sub

when column "kode"(radgridview column index no1) validating ( i mean when it empty string, or hit enter, something like that ... ) 

Thanks dess

[Dess | Tech Support Engineer, Principal]

Hello, Hengky,

To be honest, using a separate form with a RadGridView that uses its search row for finding the matches is the best possible performance that you can get. RadGridView internally uses a BackgroundWorker for its search functionality and it produces quite good performance.

The following KB article demonstrates a sample approach how to edit a row in the grid via a dialog: https://docs.telerik.com/devtools/winforms/knowledge-base/edit-a-cell-in-gridview-with-a-dialog You can use a similar approach and build any custom dialog that you would need for covering your scenario.

Should you have further questions please let me know.
