I have a radgrid bound by entity datasource and has the following column:

<telerik:GridTemplateColumn UniqueName="Color" HeaderText="Background Color" DataField="Colour" ItemStyle-Width="150px" ItemStyle-HorizontalAlign="Center"
                                    SortExpression="myColor" AllowFiltering="false" HeaderStyle-Width="32px">
                                    <ItemTemplate>
                                        <div style='width: 16px; height: 16px; background-color: #<%# Eval("Colour") %>'></div>
                                    </ItemTemplate>
                                    <EditItemTemplate>
                                        <telerik:RadColorPicker runat="server" ShowIcon="true" ID="RadColorPicker1" SelectedColor='<%# System.Drawing.ColorTranslator.FromHtml("#" + Eval("Colour")) %>' />
                                    </EditItemTemplate>
                                </telerik:GridTemplateColumn>

 

The datasource looks like this

 

<asp:EntityDataSource ID="eds1" runat="server" OrderBy="[it].Name" ConnectionString="name=DBSchoolsEntities" DefaultContainerName="DBSchoolsEntities" EnableDelete="True" EnableFlattening="False" EnableInsert="True" EnableUpdate="True" EntitySetName="Classifications" EntityTypeFilter="Classification">
                    </asp:EntityDataSource>

I have other columns on the grid that dont have EditItemTemplates and these fields update in the db just fine, but the colour picker column doesnt update in the database and I dont know why?

Hi Andrew,

Try to use a two-way binding expression for the value of the ColorPicker. Replace Eval with Bind and see how the behavior changes.

If you would like additional information on binding expressions you would find the following article interesting.
