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

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!

after the data source for the grid is being updated the columns adjusts them widths perfectly by using "BestFitColumns(BestFitColumnMode.DisplayedCells)" ,but what i wan to acheive next is to resize the hole grid based on the new size of the columns , i have set the autosize property to true and also tried AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill but that stops the columns to adjust based on the text inside , can't i adjust both together columns and hole grid width ??

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

Best Regard

Hello all!  It's been a while :)

I'm working with your radDock control to give my Users a more graceful way of managing their visual data and so far it's working out quite well with one notable exception:

When a User has multiple DocumentWindow docked, the look and feel is fine (VS2012LightTheme) and looks like the image in DockSample1.  However, this is not the intended layout - it's merely the default for when new windows are opened.  Once opened my User move the windows to their desired locations as seen in image, DockSample2.  This is where the trouble is.

1) Which document has focus?  Only those with outstanding eyes can tell.

DockSample3 shows the effect I'm going for.  At a glance, this is only touching the BackColor of the TabStripItem but in fact I need to adjust all of the following:

BTW - I am GUESSING that this is a TabStripItem!  Please forgive me if i got this one wrong, and correct as needed :)

TabStripItem BackColor and Font Forecolor when Tab is ActiveWindow, Mouse Over and Not ActiveWindow

I did find a number of possible solutions in the Forums but most are for much older versions of Telerik UI for Winforms and did not translate.

Any help you can provide would be very helpful.

Kindest regards,

Curtis
