Questions on UI for ASP.NET AJAX Forum

Greetings.

I'm using RadGrid with an ObjectDataSource and SQL Server. All works well. However, I would like to have more control over when the changes to the data are sent (updated) to the database. That is, I would like to allow the user to make changes in multiple rows of the grid, and then save them when he presses a "Save" button or discard them by pressing a "Cancel" button.

I set AllowAutomaticUpdates to false, but then the user's changes to the data are lost when he presses "Update."

I've done my due diligence with the documentation, forums and such, but can't find the solution.

Thanks.

set blank text to GridDropDownColumn when no matching value

Hi,
I have a GridDropDownColumn which is bound to a datafield.
The column works very well - shows the right text for the corresponding values.

Problem is when the datafield holds a value which does not exist in the DropDown DataSource the Column always displays the first value in the DataSource.
My wish is to display a blank value (not text) when there is no matching Value in the dataSource.

Is there an easy way to do that (I mean without catching the ItemDataBound event and manually checking each value against the dataSource).

Thanks,
Revital

Display a field vertically

I have a grid in my web site with a GridTemplateColumn inside and I am using <ItemTemplate> to layout a custom appearance.
Here's the ItemTemplate contents :

    
            <asp:Image ID="Image1" Style="float: left;" Width="171px" Height="167px"   
        
                                                ImageUrl='<%# "ImageFromDB.ashx?ID=" + Eval("KeyID") %>' runat="server"   
        
                                                AlternativeText="Stock Image" />  
        
                                            <div>  
        
                                                <span style="font-weight: bold; font-family: Arial Black;">Description:</span>  
        
                                                <%# Eval("Description") %>  
        
                                                <br />  
        
                                                <br />  
        
                                                <span style="font-weight: bold;">Manufacturer:</span>  
        
                                                <%# Eval("Manufacturer") %>  
        
                                                <br />  
        
                                                <br />  
        
                                                <span style="font-weight: bold;">Code:</span>  
        
                                                <%# Eval("Code") %>  
        
                                            </div>

I want to enter two dynamically created divs to the left of the template that will appear vertically with a Field Description inside.
How can I do that?
Thank you very much!

How to access the Ajax Panel in a popUp Window

I have a base page (Default.aspx) and two pop-up windows (PopUp1.aspx and PopUp2.aspx). When I click a button in Default.aspx I bring the PopUp1.aspx as a modal window. For some purpose I need to open another PopUp window (PopUp2.aspx) from the PopUp1.aspx as the second pop-up window.

And when I close each of these windows I need to perform some server side actions.So I have OnClientClose event in my Window manager. All required JavaScript codes are called from a file named Default.js and every aspx file has a referance to it.

To visualize the example please refer to the shape below:
http://www.freeimagehosting.net/uploads/c8747568ca.jpg

Everything runs OK until I close the second poup and try to call raise a request to the ajax panel in the first popup. I mean

    
            ajaxManager = $find('ajaxPanelMain'); 
        
            ajaxManager.ajaxRequest('UpdateMain');

code works fine but

    
            ajaxManager = $find('ajaxPanelPopUp1'); 
        
            ajaxManager.ajaxRequest('UpdatePopUp');

crashes because it can not find the Ajax Panel "ajaxPanelPopUp1" which is in the PopUp1.aspx. IT seems that this code can only see the Ajax Panel at the main page "Default.aspx". How can I call the Ajax Panel in the first pop-up window PopUp1.aspx?

Regards & Thanks in advance.

Usercontrol GUI lock by Ajax

Hi

I have countered a problem using your radgrid, ajax and webusercontrol on insert

Im trying to create a new record using the built in "add new record" from CommandItemDisplay="Top". A webusercontrol shows up a everything is fine.

But:
In my usercontrol i have a textbox where I have a OnTextChanged event which sets up some settings for the user.
Now when i hit the tab-button the event fires correctly but after that my usercontrol GUI is locked. That is when i try to click on any other textbox inside my usercontrol is gets the "focus" or "pipe blinking" but i cant enter any text.

If I mark anything outside the usercontrol or have a button in the usercontrol that gets the focus it allows me to use the textboxes again.

I've trying running the usercontrol in another .aspx without it beeing used in a radgrid and that works fine. It is also working in the grid when im not using any Ajax.

This is how I use the Ajax:

    
            <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                        <AjaxSettings> 
        
                            <telerik:AjaxSetting AjaxControlID="radGRegisterTime">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="radGRegisterTime" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
                        <AjaxSettings> 
        
                            <telerik:AjaxSetting AjaxControlID="radGRegisterTimeSecondaryTasks">  
        
                                <UpdatedControls> 
        
                                    <telerik:AjaxUpdatedControl ControlID="radGRegisterTimeSecondaryTasks" LoadingPanelID="RadAjaxLoadingPanel1" /> 
        
                                </UpdatedControls> 
        
                            </telerik:AjaxSetting> 
        
                        </AjaxSettings> 
        
                    </telerik:RadAjaxManager> 
        
                    <telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Height="75px" Width="75px" Transparency="10">  
        
                       <img alt="Loading..." src='<%= RadAjaxLoadingPanel.GetWebResourceUrl(Page, "Telerik.Web.UI.Skins.Default.Ajax.loading.gif") %>' style="border:0;" /> 
        
                    </telerik:RadAjaxLoadingPanel>

The problem also occurs when using ms updatepanel.

So im thinking if there could be some threading that kinda lock the control.

Hope you see my problem.

Thanks in advance

A Couple of Bugs

Have noticed a couple of bugs whilst developing a wrapper for your Window controls.

I think it would help you to know that with my wrapper, every window gets spawned from window.top where there is an instance of RadWindowManager exposed. This is to prevent dialogs opening inside each other.

Bug 1:
When multiple modal windows are open (non-modal can be open too) and I call the cascade() function, the modal windows become non-modal.

Bug 2:
To see this bug you need to do the following...
- Open a Modal Dialog that has a link inside that will spawn another modal dialog (from window.top).
- Ok, so we've got a dialog open - now click the link to spawn the second dialog and then quickly right click in some whitespace of the first dialog, before the second one has appeared. Wait for dialog 2 to render and load. Your browsers context menu should still be visible. If you then click on Refresh (IE), or This Frame > Reload (FF) the first dialog will reload and re-render itself on-top of dialog 2!

I am personally not overly bothered about bug 2, but bug one is a little annoying, as I want our clients to have an always-on-top global controls panel that contains a Cascade Windows button.

Any help is greatly appreciated!

Bind SPList to RadGrid

Hello,

We have tried to bind SPList to the RadGrid using two strategies that we saw in the examples and forum.
1.To use the method SPList.GetDataTable() and to bind the dataTable to the RadGrid. The problem with this option that GetDataTable() contains only String and Int32 types, no Boolean and other types of SPField.
2. The second strategy was to bind SPListItemCollection of the list (we tryed to return spesific columns and all items).
The problem here is RadGrid does not display all columns that are in SPListItemCollection, particulary it does not display the columns that were added manually from sharepoint UI. We work on server side, we also tried autogenerate columns and custom generate, in both cases there is no results in RadGrid.

Can you please sent us some example of how to bind SPListItemCollection to RadGrid or any other way to bind SPList to RadGrid.

Thank you,
Shiri.
