Hi!

I need use a different image from data base, i will asign the image(PNG) in order of an specific process.

The images recovered from data base are created in a temporal folder in order to use them in the dynamic process when i need chage the image.

At this moment the asignation of an image is ok but i can not see the image in the button:

RadRibbonButton objArea = new RadRibbonButton();
objArea.LargeImage = new BitmapImage(new Uri(auxPath + (string)dt.Rows[i].ItemArray[1], UriKind.Relative));
objArea.Size = Telerik.Windows.Controls.RibbonView.ButtonSize.Large;

If i use a RadRibbonButton created manually in xaml, i can change the image and the result is ok.

//control created in xaml
btnExample.LargeImage = new BitmapImage(new Uri(auxPath + (string)dt.Rows[i].ItemArray[1]));

If you help me i will be greateful.

Hi,

i'm looking for help with removing lines/border from column where i have hierarchical tree.

Property GridLinesVisibility is not solution because removes/adds lines in whole grid, but i want remove only in my first column.

I created styles based on GridviewCellStyle and applied them to cells, but without any results. RadTreeListView shows or not lanes only according to GridLinesVisibility, my styles changes nothing.

Best regards,

Jakub.

        <Style TargetType="telerik:GroupHeaderRow">
            <Setter Property="ShowGroupHeaderColumnAggregates" Value="True" />
            <Setter Property="ShowHeaderAggregates" Value="False" />
        </Style>

But the result is double lines: one for group title and another to aggregates.
I wanna aggregates in same line that group title but in collumns.

Regards, JP.

On RowValidating, when a GridViewCellValidationResult is added with a PropertyName such as "Hours", and a column that precedes the Hours column has a binding path of say "SourceHours", the GridView logic incorrectly does a .Contains() on the PropertyName to get the cell, which leads to the SourceHours column being highlighted as the one with the validation error, instead of the Hours column.

I'm using Telerik.Windows.Controls.GridView, Version=2015.3.1104.45, and the offending method is Telerik.Windows.Controls.GridView.GridViewRow.TryGetCellFromPropertyName.

Here's the relevant XAML:

                    <telerik:GridViewDataColumn Header="Source Hours" DataMemberBinding="{Binding SourceHours}" DataFormatString="n" TextAlignment="Right" />

                    <telerik:GridViewDataColumn Header="Hours" DataMemberBinding="{Binding Hours}" DataFormatString="n" TextAlignment="Right" />

And here is how I'm adding the GridViewCellValidationResult in the RowValidating event handler:

if (attendance.Hours == 0m) {

    e.ValidationResults.Add(new GridViewCellValidationResult { PropertyName = "Hours", ErrorMessage = "Hours cannot be zero."});

}

And this is why it's failing ( the Contains(this.propertyName) part):

internal bool TryGetCellFromPropertyName(string propertyName, out GridViewCell gridViewCell)
        {
            Func<GridViewBoundColumnBase, bool> func = (GridViewBoundColumnBase c) => c.GetDataMemberName().Contains(this.propertyName);
            GridViewDataControl gridViewDataControl = base.GridViewDataControl;
            if (string.IsNullOrEmpty(propertyName) || gridViewDataControl == null)
            {
                gridViewCell = null;
                return false;
            }
            gridViewCell = (
                from c in base.Cells.OfType<GridViewCell>()
                where c.DataColumn != null
                select c).FirstOrDefault<GridViewCell>((GridViewCell c) => func(c.DataColumn));
            return gridViewCell != null;
        }

If it instead was coded as c.GetDataMemberName() == this.propertyName (or similarly ignoring case if desired), it seems to me that it would work as expected.

For now I will use a UniqueName to get around the issue, but I wanted to bring it to Telerik's attention.

Hello.

I'am trying to bind ViewModel property to a CommandProperty of a GridViewCheckBox inside of CreateCellElement. Unfortunately the binded command doesn't run while clicking on checkbox. Any ideas why this isn't working?

I'm posting the code where I belive is the mistake. I have made a test Visual Studio 2013  project to try to solve this. It is enable to download here: HERE

Creating  cell element:

Any ideas? This error consumed 1 day of my work for now..

I was trying to figure out why the titles of my RadPanes were not being translated.  I finally figured out that the LoadLayout() also loads the header of the panes and that overrides my XAML's {x:Static properties:Resources.xxx}.

I could say "After the LoadLayout(), change the title of each pane according to the resource strings" but it would be nice if it could be done directly in the XAML.  I don't believe there's a way to prevent the "Header" tag from being included in the SaveLayout/LoadLayout functions, right?  To tell you the truth, I don't even see why the header is included at all!

Hi!

The DocxFormatProvider resets any Color informations of any Styles to the default light blue when I export with it.

 I export like this:

DocumentFormatProviderBase format = null;
 
format = new DocxFormatProvider();
 
format.Export(radRichTextBox.Document, File.Open(filename, FileMode.Create));

I used versions 2015.3.1104.45, 2015.3.1104.40 and 2015.3.930.40

Did i miss some setting or, if not, is there any workaround?

It works fine with the htmlformatprovider, but i need the header and footer, which is cut off by it.

Hello.

I am experiencing a problem with RadDatePicker

In my application, the user chooses Start date and End date and according to that, the grid is updated.

I would like to avoid using Refresh button, i.e. letting the user pick both dates and then click refresh to get the data.

On the other hand, I don't want to update the data each time one of the Pickers is changed, before the second one is also picked.

I would like to do it this way: when user picks one of the dates, the second DatePicker expands for him so he can immediately choose a second date, and no need to click a refresh button. What happens is that DatePicker.IsDropDownOpen property seems not working from code behind.

In DatePicker1 SelectionChanged event handler, I am doing DatePicker2.IsDropDownOpen=true, but this doesn't work. The DatePicker2 stays closed.

Maybe there is another control, like doubleDatePicker which makes it possible to choose a range of dates? Like in CheckIn-Checkout pages on the internet, the datepicker control consists of 2 calendars.

Thanks in advance for your help.
