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:

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);

Hello Guys,

we are trying to use the Nuget to install the telerik controls instead of local installation, but I found under the winFrom project, it doesn't work, I try to search "Telerik.WinControls.ChartView",  but no expected results return, my telerik Nuget settings is like below:

I don't think the ".Telerik.Windows.ChartView" is what we want.

the only thing for winforms controls is named "TelerikWinCompositeUI", when I installed it,

I found the "Telerik.WinControls.ChartView" doesn't exist.

Hi,

Is it possible to get an example of how to to create a custom TextHighlightTag? To try and recreate what the 'Find All' achieves in the search dialog.

It's the only TaggerBase I'm having trouble getting working. I've literally copied the source code from TextSearchHighlightTagger.cs but no matter what when I try to use UpdateSearchWord it results in an exception 'Object reference not set to an instance of an object.'

If I don't register a custom tagger and just use:

syntaxEditor1.SyntaxEditorElement.HighlightAllMatches("Test");

It does exactly what I want to do, only that I can't seem to set the TextFormatDefinition.

What I'm hoping to achieve is to have a text field that controls what is highlighted. Custom would be ideal as I could have more than one then but for my intended purpose I'd be happy just to be able to configure the default colors.

Thanks in advanced!

Regards

I am using a default RadListView control, and wish to use custom list items. Following the directions here, I wrote the following class.

using System;
using System.Drawing;
using Telerik.WinControls.UI;
using Telerik.WinControls.Layouts;

namespace CustomListItemTest
{
    class SampleVisualItem : SimpleListViewVisualItem
    {
        private LightVisualElement sampleNumberField;
        private StackLayoutPanel stackPanel;

        public string sampleNumber = string.Empty;

        protected override void CreateChildElements()
        {
            base.CreateChildElements();

            stackPanel = new StackLayoutPanel
            {
                Orientation = System.Windows.Forms.Orientation.Horizontal,
                EqualChildrenWidth = true,
                ShouldHandleMouseInput = false,
                NotifyParentOnMouseInput = true
            };

            sampleNumberField = new LightVisualElement
            {
                StretchHorizontally = true,
                MinSize = new Size(50, 0),                
                ShouldHandleMouseInput = false,
                NotifyParentOnMouseInput = true                
            };
            stackPanel.Children.Add(sampleNumberField);

            Children.Add(stackPanel);
        }

        protected override void SynchronizeProperties()
        {
            base.SynchronizeProperties();

            Text = "";            
            sampleNumberField.Text = sampleNumber;
        }

        protected override Type ThemeEffectiveType
        {
            get
            {
                return typeof(SimpleListViewVisualItem);
            }

        }
    }
}

On the form I handle these events.

private void RadForm1_Load(object sender, EventArgs e)
        {
            ListViewDataItem newItem = new ListViewDataItem();
            newItem.Key = "sampleNumber";
            newItem.Value = "123434";
            SampleList.Items.Add(newItem);
        }

        private void SampleList_VisualItemCreating(object sender, ListViewVisualItemCreatingEventArgs e)
        {
            if (SampleList.ViewType == ListViewType.ListView)
            {
                e.VisualItem = new SampleVisualItem();
            }
        }

However the added item does not appear. If I click around enough and move the mouse off screen, the item does appear (so it does exist), but if I click off-screen again it's gone.

What am I doing wrong?

I've searched and found a few suggestions on how to do this, but none of them seem to work for me.  

Here's what I've tried in the CellFormatting event:

        e.CellElement.DrawBorder = False
        e.CellElement.BorderWidth = 0
        e.CellElement.BorderBottomWidth = 0
        e.CellElement.BorderTopWidth = 0
        e.CellElement.BorderLeftWidth = 0
        e.CellElement.BorderRightWidth = 0

and I'm still seeing a horizontal line between rows:

Clearly I'm not doing the right thing, can someone please point me in the right direction?  

Thanks!

            txt_DB_Code.Text = lb.clsGenerator.get_table_code(cboTabels.Text, dtColumns);
            byte[] byteArray = Encoding.ASCII.GetBytes(txt_DB_Code.Text);
            MemoryStream stream = new MemoryStream(byteArray);
            txt_DB_Code_syntax_editor.Document = stream;

 txt_DB_Code.Text value is :

Hi

I have a problem updating the RadMultiColumnComboBox header when I retrieve which rows in the data grid are to be selected from the database.
the lines are selected with the lines that I set to true, but they are not put in the combo box header until I use the drop down function. Can this be solved or what am I doing wrong.

Private Sub FrmTestTelerik_Load(sender As Object, e As EventArgs) Handles Me.Load
        SetCheckStateToActvityTypes()
    End Sub

    Private Sub SetCheckStateToActvityTypes()
        For i As Integer = 0 To RadMultiColumnComboBox1.MultiColumnComboBoxElement.Rows.Count - 1
            Dim item As Object = RadMultiColumnComboBox1.MultiColumnComboBoxElement.Rows(i)
            Dim id As Integer = item.Cells(0).value
            If id = GetSelectetActivityTypeIDFromDB(id) Then
                RadMultiColumnComboBox1.MultiColumnComboBoxElement.Rows(i).Tag = Boolean.TrueString
                RadMultiColumnComboBox1.Refresh()

            End If
        Next
    End Sub
