I'm using a datagrid to display records from a database.  Based on the 

value of a specific field, I want to set the "checked" property of a 

asp:checkbox control accordingly.  For example, if the value 

equals "YES", the checkbox is checked; if the value equals "NO", then the 

check box is not checked.  Any suggestions?

Depending on you datasource, use a test for equivalence:



Example for Boolean 0,1 Values:



<ASP:CHECKBOX AutoPostBack="True" Runat="Server" Checked=<%# ((int)

DataBinder.Eval(Container.DataItem,"YourBooleanField")==1) %> />



Example for "YES" / "NO" Strings:



<ASP:CHECKBOX AutoPostBack="True" Runat="Server" Checked=<%# 

(DataBinder.Eval(Container.DataItem,"YourYesNoField")=="YES") %> />



Remember that the Checked attribute expects a boolean value. I recommend 

using 0,1 values as they result in better performance.

When I use the convention you've suggested, the following HTML code is 

generated:



<input type="checkbox" checked=True  value="49">

<input type="checkbox" checked=False  value="50">



However, when the page is viewed in IE6, both checkboxes are selected 

(i.e., checked ). Did I miss something?

I think that you must write :



	<input type="checkbox" checked  value="49">

	<input type="checkbox" value="50">



And that's right
