HI

I want to show blank row at top of multicolumncombobox. My code is in vb.net

   Dim dr = dbManager.GetDataReader("SP_NewLotNo_Select", CommandType.StoredProcedure, parameters.ToArray(), connection)
        Dim dt As DataTable = New DataTable()

        dt.Load(dr)

        Try
            'Insert the Default Item to DataTable.
            Dim row As DataRow = dt.NewRow()
            row(0) = 0
            row(1) = "---Select---"
            dt.Rows.InsertAt(row, 0)

            'Assign DataTable as DataSource.
            cmbLotNo.DataSource = dt
            cmbLotNo.DisplayMember = "LotNumber"
            cmbLotNo.ValueMember = "NewLotId"

            cmbLotNo.Refresh()

            cmbLotNo.SelectedIndex = -1

            cmbLotNo.AutoCompleteMode = AutoCompleteMode.SuggestAppend
            cmbLotNo.AutoSizeDropDownToBestFit = False
            cmbLotNo.BestFitColumns(True, False)
            cmbLotNo.Columns(0).IsVisible = False
            cmbLotNo.Columns(3).TextAlignment = ContentAlignment.MiddleRight
            Me.cmbLotNo.AutoSizeDropDownToBestFit = True

            Me.cmbLotNo.AutoFilter = True
            Me.cmbLotNo.DisplayMember = "LotNumber"
            Dim filter As New FilterDescriptor()
            filter.PropertyName = Me.cmbLotNo.DisplayMember
            filter.Operator = FilterOperator.Contains
            Me.cmbLotNo.EditorControl.MasterTemplate.FilterDescriptors.Add(filter)
        Catch ex As Exception
            MessageBox.Show("Error:- " & ex.Message)
        Finally
            dr.Close()
            dbManager.CloseConnection(connection)
        End Try

its working but not perfectly as i want attaching image for output.

Thanks

I'd like to start off by saying that your code editor performs better than any of your major competitors with very large files which is great for my purpose. Really very impressed with how well it works!

That said I have a couple of issues that are really affecting my user experience with using it.

The first is there does not appear to be a word wrap option. Not sure if I am blind, but if so could you please point out how to use it?

The second is the number of lines scrolled when using the mouse wheel is far too many. Is there an option to configure this? Typically in most editors 3 is a good default. Unfortunately with this the number is 15+.

One more to top it off is the Line number margin. How do I increase the size? The number is getting cut off noticeably with anything 20,000 and above. I attached a screenshot to show what I mean for that. I might be blind again but I cannot see how to configure this in the documentation.

Morning,

I have a project in VS2022 targeting .NET 6.0 and using the UI.for.WinForms.AllControls.Net60 NuGet package. On installation of the package all controls appear in the Toolbox as expected. Upon restarting Visual Studio, all of the controls have disappeared. Attempting to re-add them manually from Choose Toolbox Items and browsing to the package DLLs results in errors as below for each DLL.

Do you have any suggestions as to why the controls won't persist in VS?

We've tried uninstalling and re-installing VS so as to start with a fresh install but the same issue occurs.

Many thanks,

John.

Dear all,

probably a very simple question

I am using a SplitContainer with four vertical panels. The default behavior is that the handles (little arrows) are always visible even when the panel is "minimized" with only one center little arrow shown as handle.. (see attached image).

If I use panel.collapsed = true, the panel is masked but the handle is not shown anymore and the user cannot act on it .

How can I do to programmatically mimic the standard interactive behavior and manipulate the three arrows ?

Many thanks

Patrick

Hi.

Im tring to design a form like this to display some info. prop3 is a list of N string where N is variable. after i learnt some controls and found that property grid with custom item is accessible. i also read the custom item in property grid and tried, but i didnt get the result i want. 

in my code, i changed enum to list<string>. and item.deliveryType to item.prop3 which type is string.

btw, i use managed c++. thanks.

In our application, we are using RadMaskedEditbox for the Phone and Fax values.

We are using the property for MaskType is Standard & Mask is (###) ###-#### & & & & & & & &

Here we need to allow only the numeric value, not special characters. (Do not allow them to enter the hyphen.)

The problem is: https://prnt.sc/xsW5oONnZLN4

Hi

I have two tables issue and receive how to show balance (issue qty )- (receive qty) balance in radgridview

Only one of two checkbox columns can be checked at any given time for any given row. 

What I'm experiencing is when one column is checked and the other is selected, both are then unchecked including the one clicked.

Sample project illustrating the issue is attached and the event handler code is below.  

What am I doing wrong?  Any help would be most appreciated.

TIA

Event handler code:

        private void Dgv_MenuItems_ValueChanged(object sender, EventArgs e)
        {
            if (_settingItemAvail)
            {
                return;
            }

            if (sender != null && sender is RadCheckBoxEditor checkBoxEditor)
            {
                var cell = checkBoxEditor.EditorElement.Parent as GridDataCellElement;
                var cellName = cell.ColumnInfo.Name;
                var row = cell.RowInfo;

                if (row.Index < 0)
                {
                    return;
                }

                _settingItemAvail = true;

                switch (cellName)
                {
                    case "Unavailable":
                        if (checkBoxEditor.Value.ToString() == "On")
                        {
                            if ((bool)dgv_MenuItems.Rows[row.Index].Cells["Available"].Value)
                            {
                                dgv_MenuItems.Rows[row.Index].Cells["Available"].Value = false;
                            }
                        }
                        break;

                    case "Available":
                        if (checkBoxEditor.Value.ToString() == "On")
                        {
                            if ((bool)dgv_MenuItems.Rows[row.Index].Cells["Unavailable"].Value)
                            {
                                dgv_MenuItems.Rows[row.Index].Cells["Unavailable"].Value = false;
                            }

                        }
                        break;
                }

                _settingItemAvail = false;
            }
        }

Hello, I am having a bit of a weird issue. It seems the mouse down event / context menu only fires when I click the the border line of the control but not the inside of the control. When I click the inside of the control I get the default windows right click menu. Is there a way to fix this? 

 Private Sub txtHomePath_MouseDown(sender As Object, e As MouseEventArgs) Handles txtHomePath.MouseDown
        If e.Button = MouseButtons.Right Then
            Dim c As New RadDropDownMenu
            c.BeginInit()
            c.ThemeName = Me.ThemeName
            Dim item As New RadMenuItem("Delete Folder") With {.Image = My.Resources.folder_delete_fatcow.GetThumbnailImage(16, 16, Nothing, Nothing)}
            AddHandler item.Click, AddressOf DeleteFolder
            c.Items.Add(item)
            c.EndInit()
            c.Show(Control.MousePosition)
      End If

    End Sub
