    Windows Store App displaying Data in two more columns in ListView

    • 2 Comments

    Windows Store apps comes with some amazing data bound controls. The most favorite among them is ListView and GridView. The ListView shows data in vertical scrolling mode and GridView shows data in horizontal scrolling.

    My pal was building an app where she needs to display data in two columns while having the vertical scrolling enabled. This forced to have two data in two columns within ListView. We tried many things on it, even reached at an extent to have two image control in DataTemplate of ListView's ItemTemplate, but anyways it was obvious that approach was wrong. Because the inside DataTemplate if we click it considers all as one item. Then we found this trick of using WrapGrid this allows the column to be formatted. So we said there will be maximum of 2 columns and the size of the image needs to be defined inside it. The whole magic of displaying data is in MaximumRowsOrColumns

    <ListView x:Name="lstData" Grid.Row="1">
    
        <ListView.ItemTemplate>
    
            <DataTemplate>
    
                <Image Source="{Binding Path=ImagePath}" Stretch="Fill" HorizontalAlignment="Left" 
    
                   Margin="10,10,0,0" VerticalAlignment="Top"/>
    
            </DataTemplate>
    
        </ListView.ItemTemplate>
    
        <ListView.ItemsPanel>
    
            <ItemsPanelTemplate>
    
                <WrapGrid ItemHeight="100" ItemWidth="150" Orientation="Horizontal" MaximumRowsOrColumns="2"/>
    
            </ItemsPanelTemplate>
    
        </ListView.ItemsPanel>
    
    </ListView>

    Windows Phone Adding Rating Button in Apps

    • 0 Comments

    Often times as a developer we get motivated to see ratings being given to our Windows Phone apps. However, this is possible only when one downloads and installs it in the Phone from Marketplace/Store.

    I was not aware that the app list (not the desktop) has the context menu to rate, earlier to that I used to go to marketplace and rate if I really like the apps. This takes some efforts considering the fact that I am using Windows Phone unlike desktop. But we have context menu in the app list apart from the two “Uninstall” & “Pin this..”. Anyways, I would love to see AppBar button which lets me rate the apps from the app itself without navigating away. This is possible through the SDK API but you need to do what I like to call as “blind coding”. Let me explain the reason behind it. Unless your app is in the store the code you write to invoke the marketplace rating page will not work. So follow the people who has tried this and working well. We need to use the “Task” and the code looks as below

    MarketplaceReviewTask rev = new MarketplaceReviewTask();
    
    rev.Show();

    This would show up the rating page of Marketplace and hence you are.

    Windows Phone Emulator Orientation is not working

    • 0 Comments

    Another classic problem of Windows Phone emulator is that it does not respond as expected if we have the support for both the orientations (Portrait & Landscape) by mentioning

    image

    it still not changing in Emulator. What could be the reason, think?

    It is because you have removed the On-Screen keyboard by pressing Ctrl+Page Up (I discussed this in my previous post), so you just need to get them back to the default mode by pressing ctrl+Page Down.

    This behavior is not regular, if you are lucky your Emulator should work as is without this trick as well. This is what I found during my tryouts.

    Windows Phone : How to use PC keyboard in Emulator

    • 1 Comments

    In Windows Phone when we use PC emulator and launch app there we could type using mouse through the onscreen keyboard. However, this is not very convenient and we would like to use our own keyboard while typing.

    So its very simple, to disable the on screen keyboard you need to press Ctrl+Page Up, to revert press Ctrl+Page Down

    But there is a problem and I am going to discuss in my next blog.
