Our enterprise has chosen Telerik as our tool to convert XLSX files to PDF. One limitation that has become an issue for our clients is that Telerik's API doesn't seem to support images in the XLSX header/footer. I've been trying to get around this limitation using the Telerik.Windows.Documents.Spreadsheet.Model.Shapes.FloatingImage class, but when I move the image past the top margin into the header region, the image gets cut off. Is it possible to work around this somehow? I was hoping to see a z-index parameter in the FloatingImage class, but nothing like that seems to exist.

Column text alignment issue.

I have two columns in the GridView. I want one column's text(including header) is on the left, the other column is on the right.

<telerik:GridViewDataColumn Header="Content" DataMemberBinding="{Binding Content}" TextAlignment="Left" HeaderTextAlignmemt="Left" />

<telerik:GridViewDataColumn Header="Date" DataMemberBinding="{Binding Date}" TextAlignment="Right" HeaderTextAlignmemt="Right" />

But it is not working, two columns are always aligned to the left. Then I used Visual Tree to check the properties. For the GridViewCell.

PART_CellBorder [Border]

Background_Over [Border]

Background_Selected[Border] etc

The default HorizontalAlignment is Stretch. I am not sure how to set the styles for the alignment.

Thanks.

How to select a folder instead of individual files

I'm looking for a way of not just selecting files for upload but entire folder structures. I was hoping I could use the CreateOpenFileDialog delegate to return the RadOpenFolderDialog however this function expects a return type of Microsoft.Win32.OpenFileDialog which the Telerik controls do not inherit from.

Any suggestions?

Dynamic Grid Columns

I am trying to get the GridView to work in a rather complex scenario that involves numerous dynamic columns all with their own editing and display criteria. I have come up with a solution that involves storing a metadata object on the column and then I bind to the properties on the metadata object in the Tag property.

This approach has been working fine or non-dynamic columns but I am unable to successfully determine the property to bind to in the cell template as the property name is decided at runtime, hence why I store it in the DynamicPropertyName property in the metadata.

I tried using a MultiValueConverter which works fine for the ConvertTo, but I am unable to provide the correct values in the ConvertBack.

This is my current cell template with the binding issue highlighted - if there is a way to also bind the Column.Tag.DynamicPropertyName property on the ParentRow. object which is a DynamicObject, then this approach would work in its current form.

                                         ShowColumnFooters="True" CanUserSortColumns="True" ShowColumnHeaders="True"
                                       AutoGenerateColumns="False"
                                       CanUserInsertRows="True"
                                       NewRowPosition="Top"
                                       GroupRenderMode="Flat"
                                       ShowColumnSortIndexes="True"
                                       ItemsSource="{Binding SizeDetailsList}"
                                         SelectionMode="Single"
                                       RowIndicatorVisibility="Visible"
                                       VerticalAlignment="Stretch"
                                         IsReadOnly="False" AddingNewDataItem="radGridSizeDetails_AddingNewDataItem">

Let me know if I miss anything.

Thanks

Dilip

RadDataBar: How to make the text fit at the end

I need to get the fit of the maximum on the length of the control, either that or move the label below the line.

For the first option, I was thinking of reducing the value,and then customizing the labeltext that shows up. Only issue is, not sure how to modify the textblock that shows that value.

Second option, kind of related to the first one, how can I use a datatemplate to have a template where the label is below the line?

Please refer to image attached.

Thanks!

RadLegend

Hello,

I am struggling to include a <telerik:RadLegend> tag in my code. I have been using your documentation at http://www.telerik.com/help/wpf/radlegend-overview.html as a reference but always get an error message.

I have included a reference to Telerik.Windows.Controls.dll as well as including xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation" as a namespace declaration in my XAML, but whenever I try to use a <telerik:RadLegend> tag I get an error stating "The type 'telerik:RadLegend' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been build."

Any help on this would be appreciated.

Andrew.
