Solution 1

in text property u can not provide Boolean value.

try this to checked property

<asp:CheckBox ID="chkReimbursable" runat="server"
 Text="your text"    Checked ='<%# (Convert.ToBoolean(Eval("[GroupFlag]"))) %>'/>

your groupflag value must be 'true' or '1'

Hii,
I tried that code but i am getting same issue.in my database my value 'T'and 'N'

dont use 'T' and 'N' use '1' and '0 or 'true' and 'false'' in database as value

Hi, as you said your database have value 'T' and 'N'. Then in your sp or query, you must check for this values, if 'Y' then convert to 1 and if 'N' then convert to 0. It may solve your issue.

Hii,
I used string datatype in database is it corrrect or not

Harshil_Raval 4-Sep-13 1:19am

No, for this you should use boolean value. change your db field from string to bit

if u use proper conversion then it not matter but u should take as Boolean in database for future aspects
