Questions on UI for ASP.NET AJAX Forum

Hi,
I'm just looking for the standard idiom for catching an event (a button click for example) on the client, doing an ajax postback to do a save and then displaying a dialog afterward. Basically, in my app, I have a button for running a particular report. However, before running the report I want any changes the user made to be saved. Once saved, I need to display a dialog to collect parameters for the report.
So, the psuedo code on the client would be something like this:

function OnSomeButtonClick()
{
// make a call to the server to save the current page data
// upon returning from the previous ajax call, open an RadWindow
}

If someone could kindly help me fill in the blanks I'd sure appreciate it.
Thanks ... Ed

[Solved] method registered to OnContextMenuItemClick event has no effect

In my ContextMenuItemClick event handler, I'm adding a new RadTreeNode to e.Node.Nodes, but the code has no effect.

Can you tell me why?

I have attached my small VS2008 project where the problem occurs. I had to change the extension from .zip attachment to .jpg, so detach it and rename to .zip before extracting it.

Thanks.

[Solved] Space Between RadDcoks

I would like about 3 pixels between each of my RadDocks boxes and I have set the style of each to have a bottom padding of 3px. The problem is that when the page initial loads all the docks are squished together and I have to actually move them and drop them back in place before the padding "shows up". I am using the Office 2007 skin. Any ideas on how to force space between the docks (We are calling them Widgets).

Thanks

Retaining Text in Multi Selection Combo

I have a RadComboBox with an Item Template to do multi selection. When the user clicks in the check boxes in the drop down the appropriate text is placed in the Combobox Text just as in the Telerik examples. But When the user closes the combo I want the server event OnSelectedIndexChanged to fire so I can reload other combos based on the selections from the previous combo.

The only way I could get OnSelectedIndexChanged to fire is by setting AutoPostPack to "True". But when I did that it would wipe out the text of the changed combobox. So I set EnableViewState to "False" and that wiped out the entire combobox.

How can I retain the text values in the combobox after a postback? Or am I going about this the wrong way?

    
            <telerik:RadComboBox ID="cbOrganization" Runat="server"  
        
                                    AppendDataBoundItems="True" HighlightTemplatedItems="True"                          
        
                                    OnItemsRequested="cbOrganization_ItemsRequested" 
        
                                    OnSelectedIndexChanged="cbOrganization_SelectedIndexChanged"                         
        
                                    AutoPostBack="True"> 
        
                                    <ItemTemplate> 
        
                                        <asp:CheckBox ID="chk" runat="server" onclick="StopPropagation(event)"  
        
                                            Text='<%# DataBinder.Eval(Container.DataItem, "fffb_organizations") %>'  
        
                                            oncheckedchanged="chk_CheckedChanged" /> 
        
                                    </ItemTemplate> 
        
                                    <CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation> 
        
                                </telerik:RadComboBox>

Images Disappear After Initial Dropdown

Folks,

I have seen this issue referenced, but no resolution. Essentially, it is this:

When a StartsWith or Contains Filter is used with the RadComboBox, the images disappear in the dropdown after the first Open. I noticed that if a full postback occurs, the images will eventually show again, but if AJAX is used on the selecteditemchanged event then the images are forever gone until the entire page is reloaded. I have tried to workaround this is numerous ways, even trying to set the text to an initial null state...all to no avail.

What is the workaround for this issue. Under the current situation the image is essentially useless (and invisible) after a single click, regardless of how many times a user may be opening and closing it.

Thoughts? Help!

                {  
        
                    if (e.Command == SchedulerNavigationCommand.SwitchToDayView)  
        
                    {  
        
                        RadScheduler1.SelectedView = SchedulerViewType.DayView;  
        
                        RadCalendar1.SelectedDate = e.SelectedDate.Date;  
        
                    }  
        
                    else

                            {  
        
                                RadScheduler1.SelectedView = SchedulerViewType.MonthView; 

                                    // I THINK THE PROBLEM IS THAT I NEED TO SET THE MONTHS DATE HERE, BUT AM NOT SURE IN WHAT FORMAT?                   
        
                            }

                                RadCalendar1.SelectedDate = e.SelectedDate.Date;  
        
                            }  
        
                        }  
        
                    }  
        
                    datetimeFilter = e.SelectedDate.Date.ToShortDateString(); // this is used elsewhere in the page          
        
                    BindData(); // binds data elsewhere  
        
                }

The viewstate error i get is

Execution
Error

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

Thanks for your help in this matter

[Solved] FilterExpression string pattern

Hi,

I have to parse FilterExpression string (grd.MasterTableView.FilterExpression), and I look for some pattern for this string.
I get Filter Expressions like:
(iif(firstname == null, "", firstname).ToString().Contains("a"))

Now I use this pattern (Regex):
.*\\(.*,.*,(.*)\\)\\..*\\.(.*)\\(\"(.*)\"\\)\\)

so I get column name, current filter function and input text.
But I'm not sure it'll be correct in all cases.

Please, help me to find valid pattern for FilterExpression.
Thanx

RadGrid Refresh button Event

I need to to a Rebind() when the Page is refreshed, but not when a new record is first inserted (I lose all of the "new" values if I do). What can I check on in order to perform the Rebind?

Particularly when the user clicks the "Refesh" button on the Grid.

Thanks
