TreeView ClientSide Events with MasterPage

Hi,

I am using RadTreeView in my project. If my page has not a masterpage ClientSide events of TreeView working exactly. But if it has a masterpage, i can't use scripts that is related with events. In example, i can use Drag& Drop events/scripts if my page has not a masterpage, but if has, i can not use these events/scripts.

How can I solve this problem,

Thanks for your help.

Edit : Oops! I solved this problem :) I used $find('RadTreeView1'), but in MasterPage; naturally tree's id changing so i change my function to $find('<%= RadTreeView1.ClientID %>') and worked :)

[Solved] RadCombo in Toolbar

Hello

I have a RadCombo in the template for a RadToolBarButton in the RadToolBarDropDown.

I want to allow the user to make a selection from the Combo Box and then have him click the RadToolBarButton to perform the post back.

As soon as a selection is made from the combo box the RadToolBarDropDown closes.

I want to be able to leave the RadToolBarDropDown open after a selection has been made in the combo box and hence avoid an extra click which is currently needed to reopen RadToolBarDropDown.

I have attached the image with this message.

Any insight will be greatly appreciated.

Thanks
Imran

Export To Excel From Rad Grid

Hi Telerik,
While Exporting to Excel, i am getting error like

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I am using the VB Code as bellow

    
            If (Not RadGrid1.MasterTableView.Items.Count = 0) Then   
        
            With RadGrid1   
        
             .ExportSettings.IgnorePaging = True   
        
             .ExportSettings.ExportOnlyData = True   
        
             .ExportSettings.FileName = "ExportedResult"   
        
             .MasterTableView.ExportToExcel()  
        
            End With   
        
            End If

if i'll remove the line " ExportSettings.IgnorePaging = True" , it will work. but i need all the pages to be exported.

Radgrid.ExportToExcel With DataList

I've got a RadGrid that contains multiple DataList in a template column, most all the values are numeric, but not all. I can export to excel, and most everything is correct, however in my situation, I need different formats for the cells, depending on the datalist.

This is my export secion

    
                    gv.ExportSettings.FileName = Format(Now(), "MMddyyyy")  
        
                    gv.ExportSettings.IgnorePaging = True 
        
                    gv.ExportSettings.ExportOnlyData = False 
        
                    gv.ExportSettings.OpenInNewWindow = True 
        
                    gv.ExportSettings.HideStructureColumns = True 
        
                    gv.MasterTableView.ExportToExcel()

Example Output

From the sample, which is linked to above, I need a different format on the numeric values for SP, CFM, BHP and Sone, which I have working on the screen. The issue is when I export to excel trailing 0's on the decimal fields are chopped off. If it's whole number, the trailing 0's aren't chooped off. Per the link to the Example output,
SP cell c1 should be 0.000 cell K1 should be 1.000, always contain three decimals
BHP cell c6 should be 1.370, always contain three decimals

The Radgrid is a copy of the grid shown on the screen, I need slightly different formating when exported versus what's shown on the screen. I've wired up the ExcelExportCellFormatting event to gv

    
            AddHandler gv.ExcelExportCellFormatting, AddressOf Me.gv_ExcelExportCellFormatting

I can get the individual datalist in this event, but how do I apply a specific format to the Cells within the Datalist whenexported to Excel?

Hopefully I've provided enough info to get some assistance here, of not let me know and I'll try respond with additional info.

Thanks in Advance

How to get detail table client id on the OnHierarchyCollapsed/OnHierarchyExpanded

Hi,
I have a grid with 3 level hierarchy. I wanted to get the client id of the expaned/collapsed detailtable when the expand/collapse image button is clicked.The detailtable just below the button expanded/collapse.
I can get this work for two level by the following code

    
             <ClientSettings AllowExpandCollapse="True"> 
        
                                            <ClientEvents OnHierarchyCollapsed="Collapsed" /> 
        
                                            <ClientEvents OnHierarchyExpanded="Expanded" /> 
        
            </ClientSettings> 
        
            <script type="text/javascript" language="javascript"> 
        
                function Collapsed(sender, eventArgs) { 
        
                    var radgrid = sender; 
        
                    var detailTablesArray = radgrid.get_detailTables(); 
        
                    document.getElementById(detailTablesArray[eventArgs.get_itemIndexHierarchical()]._data.ClientID).style.display = "none"; 
        
                } 
        
                function Expanded(sender, eventArgs) { 
        
                    var radgrid = sender; 
        
                    var detailTablesArray = radgrid.get_detailTables(); 
        
                    document.getElementById(detailTablesArray[eventArgs.get_itemIndexHierarchical()]._data.ClientID).style.display = "inline"; 
        
                } 
        
            </script>

But incase of 3 level hierarchy i get the value of "eventArgs.get_itemIndexHierarchical()" for the level two "expand/collapse" click as something like "2:0_2" and hence not able to index the detailtable array.
I need to do this for totally different issue though it seems from code above that i am just hiding / showing the detail table. All i need is the client id for the detailtable for the expanded/collapsed row.

Appreciate any help on this.
Thanks,
Sudhir.

TabStrip + MultiPage within user control in RadGrid

I have this problem which i've been trying to resolve for quite awhile.

Here's what i have:

RadControls AJAX 2010.1 309
RadAjaxManagerProxy on a page
RadGrid
User control that's used to edit record
TabStrip and MultiPage in the usercontrol
"Update & Next" button in the user control that saves edited record and moves to the next record.

Everything seems to work fine, except:

When click Edit for the same record twice the the tabs stop changing pages within MultiPage
The tabs themselves get changes, but not the content within Multipage
If i go to another record i can change tabs ok.
Basically the first time i edit a record the tabs work, and if i try to edit it again it does not work
It irrespective of the page i'm in
Tabs on records with the same index on the page don't work on any page.

So it appears that those lines that i've opened to edit get "locked" and after that tabstrip or mutipage stops working.

Has anybody had the same issue found a solution for this scenario?

Some code snippets:
