Panel Behavior

I have created a panelbar that has 3 sections. The second section always comes up when the page is loaded. I would like for the 1st to come up instead. What properties would I set to make this happen? I have had various properties set before and nothing has helped so far. One that I was using is [ Selected="true" ] for the section I wanted to open up on when the page loads, but to no avail.

    
            <telerik:RadPanelBar runat="server" ID="RadPanelBar1" ExpandMode="SingleExpandedItem" Width="800px" Height="750px">     
        
                    <Items>    
        
                      <telerik:RadPanelItem Text="Project Search" runat="server" Selected="true" Font-Bold="true">      
        
                        <Items>    
        
                          <telerik:RadPanelItem Value="ProjectSearch" runat="server">     
        
                            <ItemTemplate>    
        
                               ...     
        
                            </ItemTemplate>    
        
                          </telerik:RadPanelItem>    
        
                        </Items>    
        
                      </telerik:RadPanelItem>    
        
                      <telerik:RadPanelItem Text="Contract Search" runat="server" Font-Bold="true">     
        
                        <Items>    
        
                          <telerik:RadPanelItem Value="ContractSearch" runat="server">     
        
                            <ItemTemplate>    
        
                              ...     
        
                            </ItemTemplate>    
        
                          </telerik:RadPanelItem>    
        
                        </Items>    
        
                      </telerik:RadPanelItem>    
        
                      <telerik:RadPanelItem Text="SOI Search" runat="server" Font-Bold="true">     
        
                        <Items>    
        
                          <telerik:RadPanelItem Value="SOISearch" runat="server">     
        
                            <ItemTemplate>    
        
                              ...     
        
                            </ItemTemplate>    
        
                          </telerik:RadPanelItem>    
        
                        </Items>    
        
                      </telerik:RadPanelItem>    
        
                    </Items>    
        
                    <CollapseAnimation Duration="100" Type="None" />    
        
                    <ExpandAnimation Duration="100" Type="InElastic" />    
        
                </telerik:RadPanelBar>

FYI - I would like to use the aspx-side to set these properties instead of the cs-side.

Any help would be great. Thanks!

Using RadEditor with FileExplorer

I've been experimenting with the FileExplorer, specifically connecting the FileExplorer to a SQL DB based on this article. So far, this solution seems to be a fit for my current needs. But, I'd like to see if I can extend the functionality so that when certain files are opened they are opened in a RadEditor (or other text editing control - but I'd prefer a RadEditor). For example, I want to be able to edit a text file (.xml, .txt, etc...) and ultimately save the changes.

I believe the above example relies on a DBContentProvider as well as a handler, which I'm not yet quite grasping, and I suspect this might effect how a RadEditor solution is implemented. So, I'm hoping someone can help me solve my objective.

I'd also like to ask for suggestions on learning resources or the like where I can learn more about what's going on here. I know the code here says a lot but there's much of it that is still way over my head. I'm hoping for something (book, video, etc...) that "holds my hand" as it explains the ins and outs of what's going on. Perhaps a bit much to ask for but I thought I'd throw it out there.

Many thanks,
Michael

Textbox in GridTemplateColumn ignored in postback

Hi;

I'm having an issue with a usercontrol I created. I've used this exact same method before atleast twice and it's always worked, but for some reason this isn't working as expected. I have a RadGrid inside the user control which contains 4 GridTemplateColumns. For some reason when I change the text in these columns the TextChanged event does not fire. Here is the code for the ascx file.

    
            <%@ Control Language="C#" AutoEventWireup="true" CodeFile="CmlDetailsGrid.ascx.cs"

I've placed a break point in the CmlGridFieldsTextChanged event but it never reaches that point when the boxes are changed.

I've also tried several different RadAjaxManagerProxy settings but no luck. What I have above is almost identical to two other controls I've written, which both trip the text changed event without any problem.

    
            <telerik:RadAjaxManagerProxy ID="RadAjaxManager_DetailsGrid" runat="server">

Grid does not refresh on Ajax

Good day!

I'm trying to delete records from a grid via javascript (__doPostBack() method). For the __doPostBack(), I'm passing in the client ID of a RadMenu. I'm able to successfully delete records from the grid, and it refreshes ok. But if I add the RadMenu to my
AjaxSetting and the Grid as the AjaxUpdatedControl, the grid doesn't refresh anymore eventhough the loading panel appears.
Why is this so?

Thank you very much.

Dynamically added row, no controls???

I have a grid that allows the user to add a new row to the list of objects that is saved in view state. The new row is added correctly, I can see them and they are populated. When the user clicks the save button, I have a method to get loop through all the rows in the grid and save the values off to an object, everything works fine EXCEPT when I try to find the controls on my dynamically added row, it can't find any of them...Am I missing something.

So to summarize:
User clicks button - add a new object to the list of objects in viewstate, set the datasource = new list of objects
User enters data and clicks the "save question" button - Loop through all of the form data and the grid and collect values to save to object. This is where I get the error because it can't seem to find the controls on my dynamic row. I have attached the necessary code.

Permissions issues on production server

Hi, we are using Q3 FileExplorer & .net 2 framework on a Windows 2003 server. We have the view, upload, delete paths set correctly, but the upload button is inactive. On the server, the security settings the Asp.net machine account, the Network and Network Service accounts have FULL CONTROL permissions applied at the root level of the site, with 'Allow inheritable permissions' Checked. I have verified that the sub folders where we are trying to upload files indeed have these permissions set as well. Does anyone know what would cause this and what I should do to get this working. I am puzzled as we have other sites on the same box configured the same way, and the file Explorer works fine (except those use Q2 Telerik rather than Q3 but I dont think this is the issue). Thanks in advance for any help on this.

Change DataFormatString for cell based on another cell

I have a situation where one column can have either dollar amounts or plain decimal amounts (these are used as multipliers) and I need to change the DataFormatString for the cell based on the value of another cell in the row.

We are binding the grid in the OnNeedDataSource event to a IList<>. I've looked at the ItemDataBound event walk throughs but I can't seem to figure out how to access the DataFormatString.

How can I do this?

Thanks
Curtis

Skype in editor

Is there a way to enter a Skype link?

<a href="skype:[Skype username]?call">Call me on Skype</a>

Does not work. It is just removed from the html-editore mode.

This is the way Skype suggest you put a button in your webb page:
<a href="skype:[Skype username]?call"><img src="http://download.skype.com/share/skypebuttons/buttons/call_blue_transparent_70x23.png" style="border: none;" width="70" height="23" alt="Skype Me™!" /></a>

Looking for a solution for this!
