Hi, everybody!
This is my first post here!

I'm having some problems to implement a checkbox inside a gridview.

My scenario is this:

I have a grid, inside this grid I have some informations (brief description) of an event.
I want to enable people select wich event they want (one or more than one).

For this, I constructed an Grid with RowExpander.
To select each event, I tried it in tree ways:

1st: I added the checkbox selection model <ext:CheckboxSelectionModel>
But, in this case, its add an "master" checkbox to select all rows, and I dont want it.
Question: can I disable this "check all" checkbox?
Question: How I can add database values (record_id field) to this checkbox?
Example: http://www.fsba.edu.br/semanaacademi...ricao/ext.aspx

2nd: I removed the checkboxSelectionModel and added <ext:RowSelectionModel>
In this case, i added an checkboxcolum in my gridview. But all checkbox came checked and te user can't uncheck or check it (cant change state).
Question: How can I enable user check/uncheck checkbox?
Question: How I can add database values (record_id field) to this checkbox?
Example: http://www.fsba.edu.br/semanaacademi...icao/ext2.aspx

3rd: Still in <ext:RowSelectionModel> and removed the checkboxcolum
In this way, i tryed to put an checkbox inside a expander, like this:


<Plugins>
<ext:RowExpander>
<Template ID="Template1" runat="server">
<div style="padding-left:40px">
<p>Ementa: {ementa}</p>
<p>Local: {local}</p>
<p>Das{hora_inicio} às {hora_fim}</p>



<ext:Checkbox runat="server" />




</Template>
</ext:RowExpander>

But, when I run the page: Parser Error Message: The 'Text' property of 'Template' does not allow child objects.


Any ideas? Can someone help-me?

Thanks!!
