Hello,

I want a listeView, and when I click on an item, layout expands smoothy to show details. 

So I decided to use RadExpander as ItemTemplate. But its not working very well. 

1. When I click on an item, it doesnt expand. I have to refresh the layout to see the expand (I refresh with scroll/unscroll). And then I can see it expand/reduce.

2.When I scroll/unscroll, its like if wrong data is displayed on cells. New text is superimposed with old text. 

 

Code below to reproduce (testing on android device).

I am open to any advice to achieve a smoothy expand on listview. 

Thanks.

Hi there,

I am using RadDataForm as a read-only Sheet to display certain detail information. That works pretty nice on android, but for iOS the layout makes it almost impossible to read any data (see attachment).

 

So my questions are:

- are there any possibities to use a line-break on iOS for long text cells?

- are there any possibilities to modify the text size. I know it is possible for the header, but it would also be needed for the value.

 

Regards,

I have a ListView where I am trying to sort by three columns: NumRejected, DueDate, Number. I have three sort descriptors:

MyListView.SortDescriptors.Add(
    new PropertySortDescriptor
    {
        PropertyName = "NumRejected",
        SortOrder = SortOrder.Descending
    }
);

MyListView.SortDescriptors.Add(
    new PropertySortDescriptor
    {
        PropertyName = "DueDate",
        SortOrder = SortOrder.Ascending
    }
);

MyListView.SortDescriptors.Add(
    new PropertySortDescriptor
    {
        PropertyName = "Number",
        SortOrder = SortOrder.Ascending
    }
);


This works until there is a null value for DueDate. What I'm trying to do is: if there is a null for DueDate don't apply that SortDescriptor, just move on to the next. So for example I have three results in the ListView with values in all columns, they get sorted by NumRejected first, then DueDate then Number. If I also have some results with no DueDate I want them to be sorted NumRejected then Number, ignoring the DueDate. These should be below the three with DueDates. 

At the moment a null on DueDate is being treated as the lowest value for that column, so they are at the top of the list.

I think a DelegateSortDescriptor might be the way to go, but I can't find any examples how to use that.

I would like to say that recently we purchased Telerik.UI.for.Xamarin and added Telerik Nuget in our app. It works fine after integration and configured with our app. But App build fails on Xamarin Mobile Center (https://mobile.azure.com) with Telerik.UI.for.Xamarin. This happens when we try to create build.

Hi,

In calendar multi day view I can see two Thursdays as day names and can't see the Sunday.

Attached the image.

Thanks

 

 

I want to show total number of elements and number of currently loaded elements in the text property of a label which is inside the DataTemplate of LoadOnDemandRowTemplate.

Setting up Text={Binding ViewModel.TotalNumberOfProducts } for the Label does't seem to work as BindingContext of the LoadOnDemandRowTemplate seems different from the pages's binding context. I couldn't figure out the correct way of implementing this with binding. Can you help?

 

I currently have a GRID with data with four columns (Hour, "Yesterday's Price", "Current Price", "Tomorrow's Price")
but they ask me that the price columns can be 1 day or more days.
How can I BINDING the columns?

 

(VIew FILE)

<telerikDataGrid:RadDataGrid x:Name="DataGrid"
                                             AutoGenerateColumns="False" 
                                             ItemsSource="{Binding EnergyPriceValues}"    >
                    <telerikDataGrid:RadDataGrid.Columns>
                        <telerikDataGrid:DataGridTextColumn  CanUserGroup ="False"   CanUserFilter="False" CanUserEdit="False"  PropertyName="Date"            HeaderText="{Binding TitleColDate}"  />
                        <telerikDataGrid:DataGridTextColumn  CanUserGroup ="False"  CanUserFilter="False" CanUserEdit="False" PropertyName="YesterdayValue"       HeaderText="{Binding TitleColYesterday}"  />
                        <telerikDataGrid:DataGridTextColumn  CanUserGroup ="False"  CanUserFilter="False" CanUserEdit="False" PropertyName="TodayValue"           HeaderText="{Binding TitleColToday}"  >
                            <telerikDataGrid:DataGridTextColumn.CellDecorationStyle>
                                <telerikDataGrid:DataGridBorderStyle BackgroundColor="Aqua"  />
                            </telerikDataGrid:DataGridTextColumn.CellDecorationStyle>
                        </telerikDataGrid:DataGridTextColumn>
                        <telerikDataGrid:DataGridTextColumn CanUserGroup  ="False"  CanUserFilter="False" CanUserEdit="False" PropertyName="TomorrowValue"        HeaderText="{Binding TitleColTomorrow}"  />
                    </telerikDataGrid:RadDataGrid.Columns>
                  
                </telerikDataGrid:RadDataGrid>

-------------------------------------

(In ViewModel, fill the object "EnergyPriceValues")

           EnergyPriceValues.Add(new GridEnergyPrices()
                {
                    Date = DateValue.Hour.ToString () ,
                    YesterdayValue = Math.Round(_energyYesterday[i].value, 2).ToString(),
                    TodayValue = Math.Round(_energyPriceToday[i].value, 2).ToString(),
                    TomorrowValue = Math.Round(_energyTomorrow[i].value, 2).ToString()
                });

-----------------------------------------

Thank you in advance :-)

 

I would like the ability to be able to go to another view and pass the id of the row clicked within the data grid I no I used to be able to do this in winforms and asp.net but the xamrain version elludes me any ideas would be most great-full. Say my id would be items id in the below grid how would i pass that to another view.

 

I xamrain I made a short jinq video to explain what is going wrong. Basically, the reference is being destroyed on every rebuild in visual studio 2019.

Only in the shared code libary, i might add which is the one i need to be an able to reference the dll as that is where my shared code base is this is a standard xamrian project and should work within it.

Dear Telerik,

we created an Application in Xamarin.Form.
Our customer asked us to make besides an android version, a Windows 10 desktop version.

We have some problems using the mouse (double click and swipe behavior) instead of touch.
In general it is hard to find the right spot where the controls recognize a mouse-action.

1)  RadTreeView
a) how to select a treeitem (RadTreeView) with double click  ?
b) is it possible to highlight the selected row ?(in this case we could add an OK and Cancel button on the bottom of the page)

 

2) RadListView

a) the buttons (delete , edit) in ItemSwipeContentTemplate are only accessible if the mouse-pointer is in the upper-left corner.
Is it possible to swipe with the mouse when clicked on cell, now matter where ?

b) double click on a cell is only registered when click some regions.

 

Could you help us out ?

 

Regards,

Henry
