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

[Solved] 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> 
        
                                            Inventory Name: 
        
                                        </td> 
        
                                        <td> 
        
                                            <telerik:RadComboBox SelectedValue='<%# Bind( "InventoryId") %>' ID="RadComboBoxInventoryName" runat="server" Height="300px" Width="300px" 
        
                                                Filter="Contains" MarkFirstMatch="true" ChangeTextOnKeyBoardNavigation="false" 
        
                                                DataSourceID="ObjectDataSourceInventoryName" DataTextField="Name" DataValueField="InventoryId" AutoPostBack="true"> 
        
                                                <Items> 
        
                                                    <telerik:RadComboBoxItem Text="" Value="" Selected="true" /> 
        
                                                </Items> 
        
                                            </telerik:RadComboBox> 
        
                                        </td> 
        
                                    </tr> 
        
                                    </tr> 
        
                                        <tr> 
        
                                        <td> 
        
                                            Attribute: 
        
                                        </td> 
        
                                        <td> 
        
                                            <telerik:RadComboBox Text='<%# Bind( "Attribute") %>' ID="RadComboBoxAttribute" runat="server" Height="300px" Width="300px" 
        
                                                Filter="Contains" MarkFirstMatch="true" ChangeTextOnKeyBoardNavigation="false" 
        
                                                DataSourceID="ObjectDataSourceAttribute" DataTextField="Attribute" DataValueField="Attribute" AutoPostBack="true">

                                                <ItemTemplate> 
        
                                                    <%# DataBinder.Eval(Container.DataItem, "Type")%>.<%# DataBinder.Eval(Container.DataItem, "Attribute")%> 
        
                                                </ItemTemplate> 
        
                                            </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...

VirtualItemCount

I have a WCF services that expose a function List<MyDataDTO> FindPagedData(pageIndex, pageCount).

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?

Thanks.

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.

Performance problem - 900 total nodes w/ 227 root nodes

I have a set of hierarchical data I am binding to a Tree List control. The source data contains 900 total rows with 227 of the being roots resulting in a long original list plus each branch can have sometimes 6 levels.

The tree list is:
1) very slow to load initially
2) very slow to expand children when expand button clicked (postback to server is slow but grid/page painting is instant)
3) focus does not go to the node that was expanded

Here's some info from the trace log

aspx.page	Begin Load	0.000159517480573648	0.000017
	Start OnNeedDataSource	0.000180190499071809	0.000021
	Start database call	0.00020058415245513	0.000020
	Finish database call	6.53778594765536	6.537585
	Start generation of parent ids	6.53783343972488	0.000047
	Finish generation of parent ids	6.56655440845135	0.028721
	Finish OnNeedDataSource	6.56660441480691	0.000050
aspx.page	End Load	14.5043473402346	7.937743

Please advise how i can speed up the performance of the grid. I read posts about Tree View having load on demand features but couldn't find documentation for the same feature for Tree List.
