[Solved] Javascript error when retrieving data when embedded in a grid

[Richard Murphy]

Hi,

I am attempting to embed a RadCombo box in a grid for adding and updating items.

<WC:CustomDataGrid ID="dgDiscWorks" Runat="server" DataKeyField="disc_work_id" ClearNewOnCancel="true">
                                                            <Columns>
                                                                <asp:TemplateColumn HeaderText="">
                                                                    <ItemTemplate>
                                                                    <%# Container.ItemIndex + 1 %>.
                                                                    </ItemTemplate>
                                                                </asp:TemplateColumn>
                                                                <asp:TemplateColumn HeaderText="Composer">
                                                                    <ItemTemplate><a href="ComposerDetail.aspx?composer_id=<%# DataBinder.Eval(Container.DataItem, "composer_id") %>"
                                                                        ><%# ComposerName(DataBinder.Eval(Container.DataItem, "first_name"), DataBinder.Eval(Container.DataItem, "last_name")) %></a></ItemTemplate>
                                                                    <EditItemTemplate><Combo:Composer id="dw_composer" runat="server" width="200px" FontSize="10px" /></EditItemTemplate>
                                                                </asp:TemplateColumn>
                                                                <asp:TemplateColumn HeaderText="Work">
                                                                    <ItemTemplate><a href="WorkDetail.aspx?work_id=<%# DataBinder.Eval(Container.DataItem, "work_id") %>"
                                                                        ><%# WorkTitle(DataBinder.Eval(Container.DataItem, "article"), DataBinder.Eval(Container.DataItem, "title")) %></a></ItemTemplate>
                                                                    <EditItemTemplate><Combo:Work id="dw_work" runat="server" width="200px" FontSize="10px" /></EditItemTemplate>
                                                                </asp:TemplateColumn>
                                                            </Columns>
                                                        </WC:CustomDataGrid>

The problem is that everytime I attempt to click or type in the combo and it, consequently, attempts to retrieve the items from the database it throws a runtime javascript error. The combo's work fine retrieving the data outside the grid - it just happens on dynamic retrieval within the grid on edit/add.

Does any know why or have a solution please?

Many thanks, Richard

Hi,

Sorry for the delay in replying.

The part of the javascript it seems to break at is:

eval("\x76arcallBa\x63\x6bDat\x61\x20= "+od+"\x3b");

If you need the full javascript which is quite long please let me know.

Thanks,

Richard

Hi Richard Murphy,

Yes, it will be more helpful if you provide more of the related JavaScript code (where it this eval(); call located?; where is this code used?).

Additionally, can you paste the RadComboBox's ItemsRequested event handler code as well?
