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

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

Dear Sir,

Telerik UI

Dear all,

I am having difficulties to fix the column size in a ListView in Detail mode.

My set up code is very simple and as follow :

        private void SetLisViewProduitBase()
        {
            ListViewDetailColumn PBaseColumn;
            rlvProduitBase.ViewType = ListViewType.DetailsView;
            rlvProduitBase.AutoSizeColumnsMode = ListViewAutoSizeColumnsMode.None;
            rlvProduitBase.HeaderHeight = 18;
            rlvProduitBase.Font = new Font(rlvProduitBase.Font, FontStyle.Regular);

            rlvProduitBase.ShowCheckBoxes = true;
            rlvProduitBase.ThreeStateMode = false;

            PBaseColumn = new ListViewDetailColumn("Code");
            PBaseColumn.Width = 40;
            rlvProduitBase.Columns.Add(PBaseColumn);

            PBaseColumn = new ListViewDetailColumn("Forme");
            PBaseColumn.Width = 50;
            rlvProduitBase.Columns.Add(PBaseColumn);

            PBaseColumn = new ListViewDetailColumn("Nom Usuel");
            PBaseColumn.Width = 100;
            rlvProduitBase.Columns.Add(PBaseColumn);

            PBaseColumn = new ListViewDetailColumn("Nom Botanique");
            PBaseColumn.Width = 100;
            rlvProduitBase.Columns.Add(PBaseColumn);

            PBaseColumn = new ListViewDetailColumn("Origine");
            PBaseColumn.Width = 70;
            rlvProduitBase.Columns.Add(PBaseColumn);

            PBaseColumn = new ListViewDetailColumn("Labels");
            PBaseColumn.Width = 70;
            rlvProduitBase.Columns.Add(PBaseColumn);
        }

While empty, the columns width are displaying fine as seen on image 1.

When I connect the Datasource (as in https://docs.telerik.com/devtools/winforms/controls/listview/populating-with-data/data-binding), all columns get the same "default" size.

As you say (in the Adding Columns doc) that using a datasource will require to set the column width within the ColumnCreating event, I have tried this.

When this event is first called after defining the columns as in the previous code, I get a NullReference exception as if the columns are not defined.

If I try to create the columns them within the event and test first for column existence, I will get a column already exist exception (An item with the same key already exist).

What am I doing wrong ?

Many thanks for your answers

Hello,

I'd like to translate parts of the date filter in the radgridview - see the pic (numbers 1, 2, 3 are in order of clicks to get to the specific filter settings).

Those red rectangles need to be translated. And the date format should be in a short form (like 11.05.2022).

How to do that? It seems it has to do something with a FilterPopupInitialized event but I don't know what to do there.

Thanks in advance.

Regards,

Tomáš

Hi

Is there a way to create a floating action button like this but in Telerik WinForms ?

Thank you.

I have a RadPageView control in a RadForm. When I show the form, the first RadPageViewPage is scaling regarding DPI as expected. But when I select the second RadPageViewPage it is not scaled. When I move the form to another screen and back, it is scaled as expected. The RadPageViewPAge contains a UserControl with another RadPageView control.

As expected:

Too small:
