GridGroupFooterItem Excel Export Formatting

I am having trouble formatting one column in the grouped footer.
I can access the GridDataItems by "item" or "e" but I have NO idea how to access the grouped footer items and change their style.

Below is what I have for code in regards to exporting to Excel and formatting the GridDataItems, but I need to format the GroupedFooterItems.

 
             protected void RadGrid1_ExcelExportCellFormatting(object source, ExcelExportCellFormattingEventArgs e)  
        
                {  
        
                    GridDataItem item = e.Cell.Parent as GridDataItem;  
        
                    item.Style["background-color"] = "#ffffff";  
        
                    e.Cell.Style["text-align"] = "center";  
        
                }

Help please!

Search results in RadGrid

Hello,

I am populating the Grid with xml dynamically from server side.
I have gone through this blog: http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/filtering/defaultcs.aspx
and looked at the filtering mechanism.

Is it possible for me to implement search (within the grid results) instead of filtering my column? Please guide me through this (considering that we don't know the column names until they are displayed).

Thanks

[Solved] RadWindow incorrect when displayed from user control

I have been using RadWindow for some time now in various applications and with no problems. I have successfully sent parm's to the window and received values back on close. I only say this so you know I've been using it for some time and am not a complete newbie.

I have a RadWindow which I am trying to display from a user control (which is, of course, located on a web page which uses a master page). When I display the window, resizing does not work, setting the title text value does not work, and setting the behaviors has no effect on the window that is displayed.

I can take exactly the same code, put it on another web page that does not use a user control or master page and it works fine. Is there something about doing this from a user control that causes the RadWindow to behave improperly?

    
                        <telerik:RadWindowManager ID="RadWindowManager1" runat="server">  
        
                        <Windows> 
        
                            <telerik:RadWindow   
        
                                id="RadWindow2"   
        
                                runat="server" 
        
                                showcontentduringload="false" 
        
                                width="900px" 
        
                                height="100px" 
        
                                title="Telerik RadWindow" 
        
                                behaviors="Close">  
        
                            </telerik:RadWindow> 
        
                        </Windows> 
        
                        </telerik:RadWindowManager>

    
                    function openy() {  
        
                        radopen("UserControls/ARadWindowTest.aspx", "RadWindow2");  
        
                    }

    
            <asp:LinkButton ID="LinkButton2" OnClientClick="openy(); return false;" runat="server">RadOpen</asp:LinkButton>

The attached file contains a screen capture of the results of this action. Please note that the RadWindow2 is defined as being 900 pixels wide, 100 pixels high, and containing a title of "Telerik RadWindow".

Is there some kind of problem with displaying a RadWindow from within a User Control? Is there something you can see that I am doing wrong, because I have taken this same code to another page (without the user control) and it has worked perfectly.

Help, please!

Why no crossfade?

I really would like to be able to crossfade images when using RadRotator in slide show mode. But option doesn't exist.

My options are to use Flash (I really don't want to do that), to go out and buy another component, write it myself from scratch or figure out how to extend the Telerik script to do it.

I'd like to try the latter with some help from Telerik if possible.

Surely it is just a matter of stacking the images in one spot and then gradually changing opacity of the top image until the one below is completely revealed. Then shuffle the top image's z-index to put it at the bottom of the stack, no?

And as far as opacity, I think there are only three CSS implementations I need to worry about:

1. Mozilla pre-CSS3 -> MozOpacity (a value between 0 and 1)
2. CSS3 compatible -> opacity (a value between 0 and 1)
3. IE -> filter(alpha=???) where ??? is a value between 0 and 100

Of course, some browser don't support opacity. They'll just ignore the dynamic changing of opacity in CSS and will change images when the top image is shuffled to the bottom of the stack.

Telerik: Can you help me get going? I'll upload the code back to Telerik.com.

TelerikModalOverlay

I have a question regarding this style class. I know that I can override this in my page to control the background opacity for modal radWindows by putting this in my page:

.TelerikModalOverlay

{

filter: progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=90) !important;

opacity: .9 !important;

-moz-opacity: .9 !important;

}

</style>

However, is there any way to modify the background shading differently for different radwindows? I have a scenario on a single page where I want the normal lightly shaded gray background (opacity=50) for one radwindow but I want a complete covering of the parent window (opacity=100) for another. The above override will set the opacity the same for both.

Thanks in advance.

The size of the uploaded file exceeds max size allowed

Hello there;

We have installed the latest version of the mosseditor in our sharepoint environment. We have ran into the max size issue when trying to upload , for example, wmv files. This particular file is 29 mbs.

I have followed suggestions to modify the Config.xml file <property name="MaxDocumentSize">512000</property>

Also I have modified, or tried to modify the maxRequestLength in our sharepoint web application , however, it was already set to 512000. After performing these changes, my expectation was to be able to upload the file, however, that is not the case.

please help.

thanks

[Solved] Hide 'refresh' button on radgrid, for all on site

I would like to be able to hide the 'refresh' button on every single radgrid on my site. I came across this page on how to hide the control manually, but if I've got a dozen radgrids on the site, it makes maintaining/adding new ones a pain. Is there some hidden property I can add to my asp skin file that would apply to all of the radgrids?
