I have a GridComboBoxColumn and would like to do searches according to what is being written, right now I have it with a datasource by code, but it is not enabled for it to be written and filtered, now I digit a letter and find the first coincidence, I would like it to search for me the whole text chain what I type, not just the beginning, I would like it to be more interactive, and to be editable, not just selectable. Does anyone know how?
Thanks in advance

Hi,

 

I have a RadDropDownList as part of my ribbon bar, is it possible to drag (then drop) the selected item onto another control ?

I have done this before using a RadListControl (and RadListDataItems) on a form which has a MouseMove handler, however the  RadDropDownList control in the ribbon bar does not have a mouse move handler.

In the ribbon bar mouse down handler, I have tried using

RadDropDownListEditableAreaElement b = radRibbonBar1.ElementTree.GetElementAtPoint(e.Location) as RadDropDownListEditableAreaElement;

but how do I get a reference to the original RadListDataItem which has some data in the Value and Tag fields ?

Regards

Toby

Hello, my English is bad, very bad 8D 

BindingNavigator don't work, when I write code:

 

RadBindingNavigator.BindingSource = tableBindingSourse;

 

however, in the standart BindingNavigator it's working this code

pls, help ^___^ 

On a number of my gridviews I have button columns which I want to have set to a fixed width, otherwise they resize very wide which just looks weird.. To add my button column as a fixed width column I do something like this:


I also have the grid set to auto resize the columns with:


The problem is that the columns no longer take up the full width of the grid as a result of the fixed width column(s).. When I manually resize the columns, sometimes it will "snap" to the width of the grid, but I want it to be done automatically when the grid loads..

Any ideas?

Hi.

How do i change the "time" color in a appointment? I have figured out to change everything else, but not this. See attached file.

I have a column with multiple data types. I'm using the EditorRequired event to set the editor as a RadDateTimeEditor or RadDropDownListEditor as needed. In some cases I set the RadDropDownListEditor's datasource to a datatable as shown in the code below. When I click in the cell, the radDropDownListEditor works perfectly, but when I click away from that cell, the cell shows the OfficeNumber (the valueMember) instead of the OfficeName (the displayMember). How do I get it to show the OfficeName?

       Private Sub dgv_EditorRequired(sender As Object, e As EditorRequiredEventArgs) Handles dgv.EditorRequired
             Select Case dgv.CurrentRow.Cells("EditorType").Value
                    
                    Case EditorType.OfficeDropDown
                        Dim editor As New RadDropDownListEditor
                        editor.DropDownStyle = RadDropDownStyle.DropDownList
                        DirectCast(editor.EditorElement, RadDropDownListEditorElement).DataSource = dtOffices
                        DirectCast(editor.EditorElement, RadDropDownListEditorElement).DisplayMember = "OfficeName"
                        DirectCast(editor.EditorElement, RadDropDownListEditorElement).ValueMember = "OfficeNumber"
                        e.Editor = editor
                End Select
End Sub

We’re having a serious performance issues with RadGridView in Telerik v.2017.1.221.40 for Winforms. It is very easy to reproduce.
The code below opens up a Form with the only control, RadGridView and then adds 5,000 rows to it. The control has a single column containing Boolean values. Since the EnableHeaderCheckBox property of the column is set to true, it is possible to manually tick the check box in the column header.
With v.2017.1.221.40, after the checkbox ticked, it takes 10 seconds to the program to actually tick the boxes in all 5,000 rows and then 7 seconds to untick them. During this time the control (and the form too of course) remains unresponsive.

In another code example, which is virtually identical to the one below (it’s part of a large application), it takes more than 30 seconds to perform the operation.

However with v.2015.1.331.40, this operation is executed instantaneously.

Environment: i7-4770 CPU @ 3.40Gz, 24GB RAM, Windows 10 Pro, .Net 4.6.
