Call Widget Function when using DataRepeater

0
0

Hi all.  Hope everyone is well.

Using the following init script,  Im able to call the  “LoadMedia”  function   just fine from a button click event on the Window.

My goal is to be able to call the  “LoadMedia” function for the widget  after adding it to a  DataRepeater, but I’m unable to do the same using any of the   events associated with DataRepeater.

 

I get an error saying “Unknown Function: LoadMedia”

 

Package name = “WaveSurfer.js”

Source = “https://unpkg.com/wavesurfer.js”

 

 

.fctbNone{ color:#000000; }
.fctbStyle0{ color:#2e75b6; }
.fctbStyle1{ color:#a31515; }
.fctbStyle2{ color:#008000;font-style:oblique; }
this.init = function(options) {
    
this.container.id = "waveform";

    // your initialization code.
    var wavesurfer = WaveSurfer.create({
        container: '#waveform',
        waveColor: 'blue',
    progressColor: 'purple'
});

this.LoadMedia = function(value){

    wavesurfer.load(value);
};

}

 

Any suggestions would be appreciated.

 

Thanks

Hi Lennox,

ItemCloned is fired when a new item is created but the new item is NOT the item on the screen. A data repeater with 1000 records and 3 visible items will fire ItemCloned 3 times, not 1000.

When the item is populated it fires ItemUpdate, is your first,
The second step, Wisej loads js packages asynchronously and therefore it is ideal to use this procedure:


//js initialization
this.init = function(options) {
// your initialization code.
this.widget = WaveSurfer.create({
container: '#'+this.getId()+"_container",
waveColor: 'blue',
progressColor: 'purple'
});
'VB Event
Private Sub DataRepeater1_ItemUpdate(sender As Object, e As DataRepeaterItemEventArgs) Handles DataRepeater1.ItemUpdate
Dim Player As Widget = e.DataRepeaterItem.Controls("Widget1")
Player.Instance.load("http://ia902606.us.archive.org/35/items/shortpoetry_047_librivox/song_cjrg_teasdale_64kb.mp3")
End Sub
Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Widget2.Instance.load("http://ia902606.us.archive.org/35/items/shortpoetry_047_librivox/song_cjrg_teasdale_64kb.mp3")
End Sub

Happy Coding,

I attached one sample

    Hello Kevin. Thank you for the prompt reply and excellent code example. The ultimate goal is to have the Data Repeater populated from a Database and call Load function with different mp3 files. I should be able to pass those values along quite easily. Thanks again.

Please find attached.

 

 

One button simply loads the widget  and call the  “LoadMedia” function by itself.

The other  populates the Repeater and tries to call the function using the  DataRepeater1_ItemCloned() event

 

I had to remove the “Wisej.Framework.dll” to keep the size of the zip file down.

Hi Lennox,

can you please post a complete sample that includes the Data Repeater and where you want to call the widget code?

Thanks in advance.

Best regards
