Excel Export - Date Formatting Based Upon Culture

I have a Grid in which dates are always displayed in MM/dd/yyyy format. However, when we export the grid to Excel, we want the date format to be culture-specific. For example, a US-based user would see 5/27/2014 for today's date while a UK-based user would see 27/05/2014.

Is there a simple way to accomplish this? Setting the Culture property of the Grid did not do the trick. I eventually solved the problem by putting some code into the Grid's ExportCellFormatting event in which I convert the Cell.Text to a DateTime (from a string) and subsequently cast the DateTime to a string for the Culture that I retrieve from Request.UserLanguages.

Thanks in advance!

Theme builder themes or built in Skins

Just wondering which is better for performance to use embedded skins, or create using theme builder and use a custom skin.

I prefer to use a custom skin as I can tweak the css to suit, rather than target the correct specificity to change an inbuilt skin.

What I used to do was take the skin form the skin folder and rename / edit that, but have found that using the Theme builder files the CSS doesn't match exactly the built in skins, so I'm thinking about going back to the built in, but curious about performance.

Rad Grid Rebind issue with multiple control parameters

I have a rad grid that is selecting fields from 2 different tables. If i have one control parameter in the SQL data source, the grid rebinds fine and shows the data. When i add an OR clause to my SQL statement in the data source configurator for another control parameter. The grid no longer rebinds. But if i test the query from the SQL data source "Test Query", the statement works fine and pulls the data it is supposed to. Any reason as to why the grid would have an issue with the SQL statement having multiple control parameters? I can post code if you need me to.

get_selectedNode

Hi Telerik Community,

I am trying to get the text for the selected node, but keep getting "undefined" Here is my javascript:

var tree = $find("<%= RadTreeView1.ClientID %>");

var node = tree.get_selectedNode();

var ParentFolder = tree.get_selectedNode().get_text();

Right now I just have an alert box to show the value of node and the value of ParentFolder but they both keep coming back "undefined" even when I have a node seleted on my RadTreeView (id=RadTreeView1). I am using version 2011.1.519.35 (not sure if that would make a difference in the syntax).

Thanks,
Joe

Add Hidden Fields to OrgChart Node/Group Item

Hi,

I have created an OrgChart and added a rendered field using RadOrgChart.RenderedFields.ItemFields.Add().

Is there a suitable way that I can add additional data to each Node/Group Item in the OrgChart without displaying it to the user and be able to access it from the client-side? Could this be done through a hidden field or through additional rendered fields?

Thanks,

Mark

The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).

We are getting this error when the following code is added to a User Control:

    
            <telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="JawbCategoryComboBox">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="JawbOccupationComboBox" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManagerProxy>

It is the <telerik:AjaxUpdatedControl> line that is causing the issue. If I comment it out, the error goes away. I read the other posts about code within the <head> tags, but the only code in the <head> section is stylesheet code. There aren't any <% %> tags anywhere in the <head> section of the master page or any of the children. Here is the exact error:

[HttpException (0x80004005): The Controls collection cannot be modified because the control contains code blocks (i.e. <% ... %>).]
   System.Web.UI.ControlCollection.AddAt(Int32 index, Control child) +8669270
   Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) +132

[HttpException (0x80004005): Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.]

   System.Web.UI.Control.RenderControl(HtmlTextWriter writer) +25
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1266

What else causes this error?

Thanks,

RadToolTip(Manager) on RadGrid column header

I have RadGrid with many custom filters and I want to use RadToolTip(Manager) to show tooltip window with information of applied filter on column with filter. Tooltip can be closed by user manually and then I programmatically remove filter. I have been trying unsuccessfully for three hours to attach RadToolTip to column header because that element does not have either server or client ID. How to open programmatically RadToolTip over column name?

Sitemap Column Question

I have been looking for a bit, and have not found the answer. I feel like I just might have overlooked it.

How does the RadSiteMap control know where to break the items into the next column. I am using one of your demos (loading it with XML from code behind - which doesn't work straight out of the ZIP btw). The menu item is set up with a RadSiteMap control with three columns. I can add and remove items from each of the groups, and it will continue to break in the same place. There are two groups under the first column, and one group under each of the others. How does it know, or - more importantly - how do I tell it when to break to another column?
