I'm trying to create a file upload or download function to the cloud in WPF.

I heard that this product can upload to the cloud, but I would like to know if it is compatible with all clouds.

I would also like to know the maximum size that can be uploaded.

In my `telerik:RadGridView`, I have configured a `CellValidating="RadGridView_CellValidating"` callback.  It successfully catches a validation error, which then invokes this code:

e.IsValid = false;
e.ErrorMessage = "Enter a valid URL with 'https://' or 'http://'";

The cell does properly receive a red border, and what looks like a tool-tip notation in the top right corner.  However, unfortunately, I am unable to see the tool-tip, regardless if I hover or click on the tool-tip.  What are perhaps the top three to five reasons this might be happening?

It is specifically the "Documentation" column above, which is a `GridViewHyperlinkColumn`, which is failing validation...with no tool-tip showing.  To be clear, actually none of the columns have a working or "showable" tool-tip.  Even so, here is the code specifically for my "Documentation" column:

    <telerik:GridViewHyperlinkColumn
        IsReadOnly="{Binding IsEditModeWithPermissions, Converter={StaticResource InverseBooleanConverter}}"
        CellStyle="{StaticResource GridViewCellStyleStretch}" IsCustomSortingEnabled="False"
        ValidatesOnDataErrors="InViewMode"
        UniqueName="Documentation"
        MinWidth="80" MaxWidth="350" Width="150"
        DataMemberBinding="{Binding Documentation}"
        Name="DocumentationColumn" Header="Documentation">
        <telerik:GridViewHyperlinkColumn.CellTemplate>
            <DataTemplate>
                <TextBlock Text="{Binding DocumentationFormatted, StringFormat='{}{0}'}"/>
            </DataTemplate>
        </telerik:GridViewHyperlinkColumn.CellTemplate>
        <telerik:GridViewHyperlinkColumn.CellEditTemplate>
            <DataTemplate>
                <telerik:RadComboBox x:Name="DocumentationBox"
                    Text="{Binding Documentation, Mode=TwoWay}" KeyDown="RadComboBox_PreviewKeyDown"
                    IsTextSearchEnabled="True" TextSearchMode="StartsWith" OpenDropDownOnFocus="True"
                    StaysOpenOnEdit="False" Loaded="RadComboBox_Loaded" IsEditable="True" >
                    <telerik:RadComboBox.Resources>
                        <Style TargetType="TextBox">
                            <Setter Property="MaxLength" Value="{Binding DocumentationColumnWidth}" />
                        </Style>
                    </telerik:RadComboBox.Resources>
                </telerik:RadComboBox>
            </DataTemplate>
        </telerik:GridViewHyperlinkColumn.CellEditTemplate>
    </telerik:GridViewHyperlinkColumn>

And here is the RadGridView initial declaration:

    <telerik:RadGridView Grid.Row="1"
        CellValidating="RadGridView_CellValidating"
        BorderThickness="{Binding GridBorderThickness}"
        SelectedItem="{Binding SelectedLineItem, Mode=TwoWay}" Pasting="UxGrid_OnPasting"
        SelectionChanged="UxGrid_OnSelectionChanged" CopyingCellClipboardContent="UxGrid_OnCopyingCellClipboardContent"
        RowIndicatorVisibility="Visible"
        ValidatesOnDataErrors="InViewMode"
        EditTriggers="CellClick"
        ActionOnLostFocus="CommitEdit" Name="uxGrid"
        PreparingCellForEdit="uxGrid_PreparingCellForEdit" Deleted="UxGrid_OnDeleted"
        CellEditEnded="uxGrid_CellEditEnded"
        KeyDown="GridKeyDown"
        ScrollMode="Deferred"
        IsReadOnly="{Binding IsGridEditable, Converter={StaticResource InverseBooleanConverter}}"
        CanUserDeleteRows="{Binding CanEditNotReleased}" CanUserInsertRows="False"
        AreRowDetailsFrozen="True" EnableColumnVirtualization="False"
        RowDetailsVisibilityMode="{Binding RowDetailsVisibility}"
        DataLoaded="UxGrid_OnDataLoaded"
        RowEditEnded="RadGridViewRowEditEnded" BeginningEdit="RadGridViewBeginningEdit"
        AlternationCount="2" AutoGenerateColumns="False" 
        ItemsSource="{Binding LineItemsView, UpdateSourceTrigger=PropertyChanged}" SourceUpdated="uxGrid_SourceUpdated_1"
        Loaded="uxGrid_Loaded"
        LoadingRowDetails="UxGrid_OnLoadingRowDetails"
        ColumnWidthChanged="GridViewDataControl_OnColumnWidthChanged"
        DataContext="{Binding}"
        ColumnReordering="uxGrid_ColumnReordering"
        CanUserSortColumns="{Binding IsEditMode, Converter={StaticResource InverseBooleanConverter}}"
        IsFilteringAllowed="{Binding IsEditMode, Converter={StaticResource InverseBooleanConverter}}">

Use Case

our users have the possibility to save and load their own RadGridView filter settings.

One user want to get all entries where the value of the property \ column "CreateionDateUtc" is older than 90 days.

Problem

Currently you can only configure Is Less Than "Fixed Date". That means you have to change the "Fixed Date" every day to get the required result.

Is there a possibility to add a filter to the DateTime Column for example Less than 90 Days?

Thanks

Hi,

Is there a way for a telerik radbutton to only show the image that's chosen for a button? 

Opacity is at 100% yet i am still seeing the actual button outline and grey fill/background around my buttons.

See below image.

Thanks

Hello!  I'm interested in the VirtualGrid control for WPF, since the demo looks very fast for very large data sets.  For our application, we want to show a column group header, to indicate that a set of columns are related to each other.  In this dummy example, the data for four people is displayed.  We'd like to indicate that there were four groups of results for each person, and have the results displayed under each group like so:

Ideally, the Row header (the name of each person), the Column headers and the Column Group headers should be fixed, so the user can scroll the rows and columns at will, but still see the headers.   We would also like to be able to capture mouse inputs when the user clicks on a column or row header or the group header, if possible.

Is something like this possible using the control? 
Thanks,
Ed

I need help with the node shape I have provided in the image. If this type of node can be drawn in your control , then can you please provide me with the code of the chart drawn in diagram control with the help of node (as per layout shown in attached png file) (include three or four nodes for the example).

I have tried to use it in custom shape but I didn't get any success.

I am using ui for WPF ( version latest ).

If you can help  me out with this problem  (as I have failed by other tool providers) then i might think of purchasing your product license soon.

Hello

I have a RadRibbonView that I would like to set some properties, and assign events, through the page code-behind.

e.g, setting the text on the various RadMenuItems in the Ribbon.

Any suggestions or help on how to do this is appreciated.

Thanks!

I am currently using a RadCartesianChart and ChartSeriesProvider to display multiple ScatterPointSeries.  These series will have 10's of thousands of points in them.  The only rendering option that has worked well for this is BitmapRenderOptions. However, when using BitmapRenderOptions I can't get tooltips to show and I can't select any points.

Is this a know limitation of the BitmapRenderOptions or is there a way to get it to work?  I'm basically using the Large Data demo but trying to add a selection and tooltip behavior. 

Selection and tooltip work fine if I use the default XamlRenderOptions, but the performance is too bad to use.
