JS error in SelectorField


I've placed SelectorField into my GridView to have a RadioButton column there.
<mb:SelectorField SelectionMode="Single" AutoPostBack="false" />
When my page loads IE reports a JS error:
Line: 5
Char: 19
Error: 'MetaBuilders_SelectorField_CheckAllBoxes' is undefined
Code: 0
URL: (mine)
How to fix it ?
I looked into the JS file, it seems like this variable/array was not defined anywhere...

Same error. I used the SelectorField in a GridView which sits inside a usercontrol. Always shows the js error 'MetaBuilders_SelectorField_CheckAllBoxes' is undefined'.

Anyone got any ideas? Thanks

For me, this error occurs when the GridView that contains the SelectorField is not Visible. In this case, MetaBuilders_SelectorField_CheckAllBoxes is undeclared. To test for an undeclared JavaScript variable, you could use typeof(). In "SelectorFieldScript.js" change the first function so that it looks like this:

function MetaBuilders_SelectorField_Init() {
if ( typeof( document.getElementById ) == "undefined" ) return;
window.MetaBuilders_SelectorField_Fields = new Object();
if (typeof(MetaBuilders_SelectorField_CheckAllBoxes) != "undefined") {
    for( var i=0; i < MetaBuilders_SelectorField_CheckAllBoxes.length; i++ ) {
        var info = MetaBuilders_SelectorField_CheckAllBoxes[i];
        var checkAllBox = document.getElementById( info.ID );
        checkAllBox.participants = new Array(); 
        MetaBuilders_SelectorField_Fields[ info.Field ] = checkAllBox;

        for( var j=0; j < MetaBuilders_SelectorField_CheckBoxes.length; j++ ) {
            var selectorInfo = MetaBuilders_SelectorField_CheckBoxes[j];
            if ( selectorInfo.Field == info.Field ) {
                checkAllBox.participants[ checkAllBox.participants.length ] = document.getElementById( selectorInfo.ID );

I just downloaded v0.9.4, converted the old RowSelector to SelectorField, converted my DataGrid to a GridView, ran my code and immediately encountered the error 'MetaBuilders_SelectorField_CheckAllBoxes' is undefined'.

Any chance someone could fix this?

Also: According to the documentation CheckAllBox(es) is used when SelectionMode = Multiple. I've set SelectionMode = Single.

Is there a workaround? Perhaps I can setup an empty CheckAllBox object and the JS code will function w/o error?
There's no example in the documentation so I don't know how to set up an CheclAllBox object.

Hi guys...

I found the same problem and i fix it when i put the follow block of code.
<script type="text/javascript"> //<![CDATA[ var MetaBuilders_SelectorField_CheckAllBoxes = new Array({ Field:'ctl00_ContentPlaceHolder1_GridView1_SelectorField1', ID:'ctl00_ContentPlaceHolder1_GridView1_ctl01_ctl00' }); var MetaBuilders_SelectorField_CheckBoxes = new Array({ Field:'ctl00_ContentPlaceHolder1_GridView1_SelectorField1', ID:'ctl00_ContentPlaceHolder1_GridView1_ctl02_ctl01' }, { Field:'ctl00_ContentPlaceHolder1_GridView1_SelectorField1', ID:'ctl00_ContentPlaceHolder1_GridView1_ctl03_ctl01' }, { Field:'ctl00_ContentPlaceHolder1_GridView1_SelectorField1', ID:'ctl00_ContentPlaceHolder1_GridView1_ctl04_ctl01' }); //]]> </script>

You need to download the source of MetaBuilders.WebControls,
open it in VS,
then edit the file "SelectorFieldScript.js", as DarthRob pointed out
then rebuild and you're done!

Hi guys,

I am having the same problem here, did any one manage to get it working,
can any one attach the generated dll file after changing the first function in "SelectorFieldScript.js" as DarthRob pointed out.
