Hello,
At run time, my Rascheduler displays a blank header (please see attachment) (on Windows 7). I'm using Telerik version 2011.2.712.40 with VisualStudio 2010. In the designer, the header is shown as expected.
Does anyone have this problem? Thanks.

Below is my simple aspx file.

Radwindow, can I go back to previous page?

Is there back/forward navigation like in a webbrowser. For example in the demo of Radwindow I can open up Google in a radwindow and do a search. If I click on a link how do I go back to the search results.

I could save the NavigateUrl property and reload that page when the user clicks a back button. I was just hoping it was built in.

Thanks,
Corey

How to call a Javascript function from RadGrid Update Button

Hello,

I have a Radgrid in my web application . When I edit a row in the Radgrid, I want to call a javascript function (which will get the geocodes ) from the update button. I know we can add the attributes if the button is on the form. But that is not the case now.

I am accessing that update button in the itemDatabound event like this

Dim editItem As GridEditFormItem = DirectCast(e.Item, GridEditFormItem)
Dim updateButton As ImageButton = DirectCast(editItem.FindControl("UpdateButton"), ImageButton)

Appreciate the Help
Thanks

ObjectDataSource bound RadComboBox inside RadGrid

I have a EditFormSettings FormTemplate inside a RadGrid that contains two comboboxes:
(Looks something like this):

    
            <FormTemplate> 
        
                                <table> 
        
                                    <tr> 
        
                                        <td>

                                        <td>

                                                DataSourceID="ObjectDataSourceInventoryName" DataTextField="Name" DataValueField="InventoryId" AutoPostBack="true"> 
        
                                                <Items> 
        
                                                    <telerik:RadComboBoxItem Text="" Value="" Selected="true" /> 
        
                                                </Items>

                                        </td> 
        
                                    </tr> 
        
                                    </tr>

                                            </telerik:RadComboBox> 
        
                                        </td> 
        
                                    </tr> 
        
                                    <tr> 
        
                                        <td align="left" colspan="2"> 
        
                                            <asp:Button ID="btnUpdate" Text='<%# (Container is GridEditFormInsertItem) ? "Insert" : "Update" %>' 
        
                                                runat="server" CommandName='<%# (Container is GridEditFormInsertItem) ? "PerformInsert" : "Update" %>'> 
        
                                            </asp:Button>&nbsp; 
        
                                            <asp:Button ID="btnCancel" Text="Cancel" runat="server" CausesValidation="False" 
        
                                            CommandName="Cancel"></asp:Button></td> 
        
                                    </tr> 
        
                                </table> 
        
                            </FormTemplate>

Simple enough... There are two RadComboBoxes with two different ObjectDataSources applied. The ObjectDataSources look like this:

    
                <asp:ObjectDataSource ID="ObjectDataSourceInventoryName" runat="server"  
        
                    TypeName="Ams.Web.BackOffice.InventoryAdapter"  
        
                    DataObjectTypeName="Ams.Core.DomainObject.Inventory"  
        
                    OldValuesParameterFormatString="original_{0}" 
        
                    ConflictDetection="CompareAllValues" 
        
                    SelectMethod="GetInventoryForComboBox"> 
        
                 </asp:ObjectDataSource> 
        
                <asp:ObjectDataSource ID="ObjectDataSourceAttribute" runat="server"  
        
                    TypeName="Ams.Web.BackOffice.InventoryTypeAttributesAdapter"  
        
                    DataObjectTypeName="Ams.Core.DomainObject.InventoryAttribute_InventoryType"  
        
                    OldValuesParameterFormatString="original_{0}" 
        
                    ConflictDetection="CompareAllValues"  
        
                    SelectMethod="GetAttributeByInventoryId"> 
        
            <SELECTPARAMETERS> 
        
                            <asp:ControlParameter Name="aInventoryId" PropertyName="SelectedValue" ControlID="RadComboBoxInventoryName" /> 
        
                        </SELECTPARAMETERS> 
        
                 </asp:ObjectDataSource>

Note, the ObjectDataSource of interest is the second, as it has a dependency on the first for one of its SelectParameters. When the page loads, I get an error stating:

Could not find control 'RadComboBoxInventoryName' in ControlParameter 'aInventoryId'.

Basically, it reports that it cannot find the control for the aInventoryId parameter (as its not rendered on the page yet).
Is it possible to use ObjectDataSources with parameter dependencies inside an edit form? If not, is there a work around?
Thanks in advance,
Tim
PS. I've tried the $ sign trick some other have posted.. No dice. (Inspected the client "name" attribute for the input control of the RadComboBox --

ctl00$ContentPlaceHolderBody$mImportMappingGrids$RadGridOrigin$ctl00$ctl07$RadComboBoxInventoryName

Nope...

If I want to use Virtual scolling and page, I need to expose a function Int32 GetTotalItemCount()?

Which is the better strategy/solutions?

And about Filtering feature, how can I work using VirtualItemCount?

Radgrid Columns in Edit Mode

Hi, I am new to this forum and new to rad controls. I have spent a little time on understanding the usage of these control and no trying to implement one.

I have a radgrid binded to a datatable(code behind). I would like to display dropdown for a column(say Prefix) with prefilled values from another datatable when in Edit Mode. I tried using GridDropDownColumn this does not display data for that column but does gives me a dropdown control in Edit mode.

I have the grid this way.
