Question

I have a gridview controller with a set of BoundField columns to my data source. I also have a CheckBoxField that I want checked depending on if that row in the table I get from the database is marked accordingly. The problem is, Oracle does not have a boolean type and ASP.NET is expecting a boolean to mark the check box. Is there some sort of work around for this?

Here is my gridview with the check box column.

<asp:GridView ID="DeviceGridView" runat="server" CssClass="SmallGridView"  
       DataSourceID="DeviceDataSource" AutoGenerateColumns="False" 
       EmptyDataText="No devices found." CellPadding="4" ForeColor="#333333" 
       GridLines="None"  OnRowCreated="GridView_RowCreated" 
       OnRowDataBound="GridView_RowDataBound"  >
    <FooterStyle CssClass="gridViewFooter" />
    <RowStyle CssClass="gridViewRow" />
    <EditRowStyle CssClass="gridViewEditRow" />
    <SelectedRowStyle CssClass="gridViewSelectedRow" />
    <HeaderStyle CssClass="gridViewHeader" />
    <AlternatingRowStyle CssClass="gridViewAltRow" />
    <Columns>
        <asp:BoundField HeaderText="DeviceID" DataField="device_id" />
        <asp:BoundField HeaderText="Device Type" DataField="device_type" />
        <asp:BoundField HeaderText="Description" DataField="description" />
        <asp:BoundField HeaderText="Enable Logging" DataField="enable_logging" />
        <asp:CheckBoxField DataField="normal_toggle" Text="Normal User Logging" />
    </Columns>
 </asp:GridView>

Instead of using <asp:CheckBoxField>, try using a template field:

<asp:TemplateField>
    <ItemTemplate>
        <asp:CheckBox ID="cb" runat="server" 
                      Checked='<%# Eval("normal_toggle") == 1 %>' 
                      AutoPostBack="true" 
                      OnCheckedChanged="YourCheckedChangedEvent"/>
    </ItemTemplate>
</asp:TemplateField>

That will make your checkbox checked if normal_toggle value equals 1 and unchecked otherwise. Adjust to your data accordingly.

Update

Added an event to the <asp:Checkbox> inside the template field.
