Disable or hide checkbox in listgrid which has selectionAppearance : checkbox

[sankg2001]

I have a listgrid which has selectionAppearance:true. I want to disbale or hide checkbox based some other column value.

Please let me know if someone has tried it successfully.

I am using 7.0 version of Smartclient. I read somewhere that the checkbox created is a autochild of listgrid. Trying to find how to get access to it so that it can be disabled/hidden.

Have you tried overriding the showIf property of a listgridfield?

[sankg2001]

Yes I tried canEdit, canEditCell, showif etc etc. but didn't work. I am currently using ListGridRecord.enabled = false to disbale selectyion of a particular record. But this is not a good solution as selection of the record should be allowed. Only checkbox should be disabled.

to gain access to the checkbox, you can use editorProperties - for example I just tried editorProperties:{disabled: true}, when in edit mode the checkbox looks disabled..may be a good point to start? Also canEdit on ListGridField renders the checkboxes as read-only

[sankg2001]

I tried editirProperties but no luck.

[acarur01]

no luck as in it doesn't show as read-only for you? If so, then there must be something wrong with your code. Mind sharing a snippet?

[sankg2001]

This editorProperties:{disabled: true}, is attached to ListGrid, ListGridField or checkBoxField , ListGridRecord.

As I want to disable the checkbox when data comes from server based on another column's value.

Please can you send code snippet as I am very new to smartclient.

editorProperties:{disabled: true}, should be attached to which component ListGrid, ListGridField or checkBoxField , ListGridRecord ?????

[acarur01]

listgridfield

[sankg2001]

I tried it in following way which is not working.

var obj = this.getCheckboxField();
obj.setEditorProperties("disabled", true);

this is a reference to ListGrid.

[sankg2001]

PLease can you tell me how to apply editorProperties on listgridfield checkbox as there is no corresponding field in list grid.

You need to override the canEditCell method.

@Override
protected boolean canEditCell( int rowNum, int colNum )
{
ListGridRecord row = this.getRecord( rowNum );// grab the record

if(//whatever you want to check)
return false;
else
return super.canEditCell( rowNum, colNum );
