[Solved] Selecting value from Radlistpicker

[RM]

I am having a little problem trying to get the selected value from the RadListPicker control.

How do I get the value from a select dropdown item, that is get the Content value “One”, “Two” etc…?

<telerik:RadListPicker  Height="49" Margin="0,5,5,0" InlineModeThreshold="6" SelectedIndex="0" Width="292" HorizontalAlignment="Left" Background="#BF15BED4" Name="rlpBottleSize">

                    <telerik:RadListPickerItem Content="One" Background="#BF15BED4" ></telerik:RadListPickerItem>

                    <telerik:RadListPickerItem  Content="two" Background="#BF15BED4</telerik:RadListPickerItem>

                    <telerik:RadListPickerItem Content="three" Background="#BF15BED4"></telerik:RadListPickerItem>

                </telerik:RadListPicker>

 

I was thinking that in the C# code you could do something like this:
string s = this.rlpBottleSize.SelectedVisualItem.ToString();

Or

string s = ((ListBoxItem)this.rlpBottleSize.SelectedItem).Content.ToString();

 

But these do not work to get the value.

Hi Richard,

Thanks for writing.
You need to get the content of the visual item. For example:

this.rlpBottleSize.SelectedVisualItem.Content.ToString();

Write again if you need further assistance.

All the best,

I just tried the above.  Rather than the Content value, I get: "System.Windows.Controls.ListBoxItem".

My specific code is this.StateList.SelectedVisualItem.Content.ToString();

???

Hi Randall,

Please try the following:

private void ListPicker_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    var item = (this.StateList.SelectedItem as RadListPickerItem).Content.ToString();
}

That didn't work either.  Generates error: "An exception of type 'System.NullReferenceException' occurred in Here I Am.DLL but was not handled in user code".

I don't understand why this.StateList.SelectedVisualItem.Content.ToString(); by itself doesn't work. 

(StateList.SelectedIndex); produces the selected index value exactly as I would expect... so why does StateList.SelectedVisualItem.Content produce the name of the control instead of the content's value?  Looks like a bug to me.

Hi Randall,

Thank you for the follow-up. Please make sure you're using the latest release of RadControls for Windows Phone. Then take a look at the attached project and let me know if you're still able to reproduce the issue.
