set checkbox in gridview based on datatable value

Question

I have a gridview control with a checkbox field and several bound fields. The checkbox field does not directly map to a field in the database. Rather, i want to read a val

Answer 1

You can do it like this:

First in sql server:

SELECT 
    CAST(CASE PROCESSED WHEN 'Y' THEN 1 ELSE 0 END AS BIT) AS PROCESSED
    NAME
    DATE
FROM ExampleTable

in c# code:

SqlCommand cmd = new SqlCommand(sql query here); 
SqlDataAdapter da = new SqlDataAdapter(); 
DataTable dt = new DataTable(); 
da.SelectCommand = cmd; 

// Save results of select statement into a datatable 
da.Fill(dt);

gridview_all_applicants.DataSource = dt;          
gridview_all_applicants.DataBind(); 

and finally in aspx:

<asp:TemplateField HeaderText="Complete">
<ItemTemplate>
    <asp:CheckBox ID="process_flag" runat="server" Checked='<%# bool.Parse(Eval("PROCESSED").ToString()) %>' Enable='<%# !bool.Parse(Eval("PROCESSED").ToString()) %>'/>
</ItemTemplate>

Answer 2

How about a database agnostic solution, just on the off chance you are using a non sqlserver database ;)

<asp:CheckBox ID="process_flag_check" runat="server" 
            Checked='<%# Eval("process_flag").ToString() == "Y" ? "True": "False" %>'
            Enabled="false"/>
</asp:Content>

Answer 3

<asp:CheckBox ID="process_flag_check" runat="server" 
            Checked='<%# bool.Parse(Eval("process_flag").ToString() == "Y" ? "True": "False") %>'
            Enabled="false"/>

</asp:CheckBox>

This one Perfectly Works.I have modified using Kevin and marco Code. Thank u Kevinv and Marco
