Checkbox Within EditItemTemplate Of GridView Column

I have a template field within a GridView to display a checkbox in edit view and some custom text in normal view.

The results of the query to populate the grid are coming back in a DataSet.

In the edit view I can't get the checkbox to accept the column that is retuning from the DataSet (which is in T/F format) as it says its not the correct type. Even if I return "true" or 1 in the column it still dosn't work.

I take it I need to convert but can't get the syntax correct in this context 

<EditItemTemplate>
              <asp:CheckBox ID="cbPostToFarm" runat="server" Checked='<% Bind("BOOL_COL")' />
            </EditItemTemplate>

You were so close! Just missing the # and the ending %>

<EditItemTemplate>
<asp:CheckBox ID="cbPostToFarm" runat="server" Checked='<%# Bind("BOOL_COL") %>'/>
</EditItemTemplate>

Note that the use of single quotes after Checked and not Double Quotes is important. You will get errors with double quotes.

This seems working for me (.net Visual Studio 2010)

<asp:TemplateField HeaderText="Ordered" SortExpression="Ordered">
                        <ItemTemplate>
                            <asp:CheckBox ID="ID_CKBOX" runat="server" 
                            Checked='<%#Eval("ordered") %>' />
                        </ItemTemplate>
                        <ItemStyle Width="8px" />
                    </asp:TemplateField>

Where 'ordered' is the one of the db field of select statement.

I got round the issue by not binding directly to the dataset but creating a strongly typed list.

I'm sure there must be a syntactical trick to get the checkbox to bind directly to a DataSet but for the sake of a simple type I gave up looking.

Use the GridView DataBound event to set the value. Inside of the DataBound event:

Ensure the row you are working with is not a Header/Footer row.
Create a reference to the CheckBox.
Create a reference to the data that is being bound.
Mark the CheckBox checked when appropriate.
