Is there a way to fully cancel a user insert of a new row programatically?

I am looking to simulate the user hitting the esc key once initiating an insert of a new row.

Thanks,

Hello everybody,

I have a problem using the element visibilty property on ElementVisibility.Collapsed on the radgridview RowFormatting event.

When i try to put the row visibility to ElementVisibility.Collapsed, there is a strange behavior, the rows are not correctly displayed.

Here is a sample that reproduces the problem :

Maybe i'm missing something, but when i replace Telerik.WinControls.ElementVisibility.Collapsed by Telerik.WinControls.ElementVisibility.Hidden, i have the expected behavior (except that the rows are not collapsed).

Thanks in advance for your answers, and sorry for my aweful english ... I'm french.

I'm using Windows 7 64 bits, with 2016.3.1024.40 version of radcontrols, and .Net Framework v4

Hi. I understand that we need to create new themes for each different appearance of a control (eg button) unless it's done in the designer etc.

It's of concern that each of the theme packets is pretty large eg 500k in size and seems an awful waste of disk space if a whole theme needs to be generated for the sake of a single control where, in my case, I'm using 4 - 5 different shaped/coloured buttons on a single form, this is the first one I'm changing to telerik out of several hundred forms in the application.

Am I understanding this correctly? Or is it possible to strip a theme packet down to cover a selection of controls with just what's needed by those controls?

If so then is it possible to add changing the functionality of the themes/visual designer to the 'wish list' for a future version please :)

I'm complete new to the Winforms. I use Progress/OpenEdge 11.6.

I build the "getting started" Example and tried to customize it.

My questions:

Is it possible to disable the context menu (Close, close all ...) for the last shown Tab, because I want one Tab always stay open?

Is it possible to float out a complete document container with all document windows in it?

When I autohide as Document, is it possible to put the information to the bottom of the form?

When I set the CloseAction to "Hide" is there a build in function to manage then hidden Documents?

Thank yout for answers

I would like to add an Add, Edit and Delete buttons to the RadGridView, similar to what is seen in this ASP.NET Ajax control

http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/commanditem/defaultcs.aspx

A colleague show me an odd behavior of a grid in a tool that I programmed.

After inserting a new row, a column with check boxes was moved and overlay a column some a little bit further on the right side. At the original position was a gap then. He show me on the screen, but I have no screenshot to show, nor I can reproduce.

Do you any idea, how this could happen?

Trying to add a RadLinearGauge, gallery is empty.

Tried using upgrade wizard, tried rebooting machine and Visual Studio (several times).

Tried Clean and Rebuild all, tried removing and re-adding gauge, nothing works.

I'm having an issue with regards to having multiple node levels in the treeview.

First I load all the data into the treeview by binding a datatable as the the source.

When you drill down in a category you'll notice that the first two nodes are not flagged as Indeterminate, but when you click on the second node to open up its children the parent nodes get refreshed and get flagged as indeterminate.

'Loads tree nodes

      Public Sub LoadItemCategories()
        mItemCategoryDT = Datalayer.ItemCategoryRetrieveByRetail(ComboItemDataAsInt(cboRetail))

        InitTree()

        tvItemCat2.BeginUpdate()
        tvItemCat2.DisplayMember = "ItemCat"
        tvItemCat2.ParentMember = "PARENT_ITEM_CATEGORY_CD"
        tvItemCat2.ChildMember = "ITEM_CATEGORY_CD"
        tvItemCat2.DataSource = mItemCategoryDT
        tvItemCat2.EndUpdate()

        ' tvItemCat2.ExpandAll()
        AddHandler Me.tvItemCat2.NodeCheckedChanged, AddressOf tvItemCat2_NodeCheckedChanged
        AddHandler Me.tvItemCat2.NodeFormatting, AddressOf tvItemCat2_NodeFormatting

    End Sub 

    Private Sub tvItemCat2_NodeFormatting(sender As Object, e As TreeNodeFormattingEventArgs)
        Dim data As DataRowView = TryCast(e.Node.DataBoundItem, DataRowView)

        If data IsNot Nothing Then

            Dim value As Object = data.Row("Checked")
            If value Is DBNull.Value Then
                e.Node.CheckState = ToggleState.Indeterminate
            Else
                e.Node.Checked = CBool(value)
            End If
        End If


    End Sub
