Only users that have Telerik installation version 2021.1.122 are affected.

Symptoms:

Clients that have Telerik installation version 2021.1.122 can not build successfully .NET Core/.NET 5.0 projects. The following error occurs while compiling the project:

The problem is a missing NuGet fallback folder.

Solution:

You should create the missing ToolboxNuGetPackages folder in the installation folder of the controls, usually at C:\Program Files (x86)\Progress\ToolboxNuGetPackages.

.NET Framework 4.8

Telerik controls 2022 R1

 

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,

I already check the "Scheduler" function for Angular on your website but It seems not as good as the other (even with the scheduler for ASP on your website). 
I wonder that if I buy UI for Angular I can make the scheduler the same as the attached picture?

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

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

Patrick

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

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:

Hi there

 

I have a column in my DataTable that is called "checked"

I want to make this a checkbox.

With this code it is not changing it:

                GridViewCheckBoxColumn checkboxcolumn = new GridViewCheckBoxColumn();
                checkboxcolumn.DataType = typeof(int);
                checkboxcolumn.Name = "checked";
                checkboxcolumn.FieldName = "checked";
                checkboxcolumn.HeaderText = "Checked?";
                this.grdIssueAcceptance.MasterTemplate.Columns.Add(checkboxcolumn);

With this it added the type nicely, but it is another field. I do not want to ADD a field. 

                GridViewCheckBoxColumn checkboxcolumn = new GridViewCheckBoxColumn();
                checkboxcolumn.DataType = typeof(int);
                checkboxcolumn.Name = "checked02";
                checkboxcolumn.FieldName = "checked02";
                checkboxcolumn.HeaderText = "Checked?";
                this.grdIssueAcceptance.MasterTemplate.Columns.Add(checkboxcolumn);

 

Regards

Kobus
