CheckColumn Checked

[Maia]

Hi,
I would like know what's the function to know if the CheckColumn is checked or no?

<ext:CheckColumn ColumnID="mnuPermissao" Header="Permissão" Align="Center" Sortable="true" DataIndex="mnuPermissao" Width="70" Editable="true">                                                                                        
         <Renderer Handler="if(checked){#{GridPanel1}.disable();}" />                                            
</ext:CheckColumn>

Hy!
I tried with function below:

<Renderer Handler="if(checked){#{GridPanel1}.disable();}" />

but error occurred

 checked is not defined

Any tip?

Hi Maia,

You can use 'value' instead of 'checked'.

A simple way of determining the parameter names is to inspect the configuration script. You should find something similar to the following.

Example

renderer : function (value, metadata, record, rowIndex, colIndex, store) { /* YOUR LOGIC HERE */ }

The first parameter is the field value.

More information regarding the renderer is also available at the following location, see

Hi Geoffrey!
I tried your tip, but when I put the Script with Renderer Checkbox disappeared from the grid. See the attachment.

<script type="text/javascript">
    var checkPermissao = function(value, metadata, record, rowIndex, colIndex, store) {
        alert(record.data.mnuDescricao);        
        
    };
</script>

<ext:CheckColumn ColumnID="mnuPermissao" Header="Permissão" Align="Center" Sortable="true"  DataIndex="mnuPermissao" Width="70" Editable="true">                                              
            <Renderer fn="checkPermissao" /> 
</ext:CheckColumn>

Tks.

Hi Maia,

The Renderer must return the html required to render the contents of that particular cell. You can confirm by returning the value.


Example

return value.toString();

Please note as well, the renderer will fire once for each record. If you're calling alert(), the alert will render once for each record being renderer in your GridPanel.


Hope this helps.

Hi Geoffrey,

para verificar se o checbox está assinalado.">In the Checbox have the function <Check handler> to verify that the checbox is marked or not.
With CheckColumn is it possible?

Tks Maia.

Hi,

You have to read check column value from the store. Do not use renderer for it. For example, for first row

Store1.getAt(0).get('mnuPermissao')
