Old-school marquee?

Hi,

I want to thank you all for your quick and helpful answers to questions. I hope that I am not posting something that has already been posted, but I have given a thorough look.

I have a specific need of an old-school marquee. You know, scrolls one line of text from right to left, continuously. I would like to pass it a string that I construct in the code-behind. This works fine for the <marquee> html element, but that is not smooth at all.

I came back to telerik because I've been around the internet and consulting other resources for many days, even weeks, and you guys are the ones that seem to help me best, though I don't know if you have any resources for my specific question. I have tried dynamic drive's marquee (smoother but freaks out and won't render at random times), many javascript resources (I can't seem to get any javascript examples to work for me... no idea why) and I don't know how flash interacts with asp.

I see you have a ticker and a rotator... could those be used in the way I need? I haven't been able to get them to render, probably because I haven't passed them data sources. Could I get them to emulate the marquee, and would it be smooth?

Thank you so much, I hope you can grant me some rest from my silly, yet difficult to solve problem.

RadRotator IE7 position issue

Hi,

I have a problem with RadRotator in IE7. Rotator is placed inside a table cell and the table (width:800px;height:450px) position is defined, so that it stays always in the middle of viewport using text-align:center and vertical-align:middle. When user resize the window then the rotator does not move (is not placed inside the table cell anymore) like it should and it falls out of its boundaries. See enclosed images. This works fine in IE8 and FF3. Can you tell me what I am doing wrong / is there any workaround for this behaviour?

Disable menu scrolling

I have a drop down menu that displays an "arrow" section to scroll down to items that would normally render at the bottom of the page. I don't want this scrolling effect to be used at all, if the menu is too long and goes past the page length I want it to just display past the page. How do I disable this function?

Problem with Single Group Expand/Collapse

Hello,

we have changed the Grid behaviour to support a "Single Group Expand/Collapse" mechanism. The property "GroupsDefaultExpanded" is set to false on the MasterTableView. Paging is set to false by default, the PageSize is set to 15 by default.
The DataSource contains 150 items, which are configured to build 5 groups.

When a group is expanded, the ItemCommand event handler is called, which collapses all group headers and expands the currently selected. AllowPaging is set to true and then "Rebind()" is called.

Consider the following scenario:
1.) The page is initially called.
2.) The DataSource is added in the NeedDataSource event.
3.) The Grid is build with 5 groups, no paging enabled, all is fine.

4.) The third group expand button is clicked.
5.) The ItemCommand event handler gets called and processes the steps as defined above.
6.) The NeedDataSource event handler gets called and retrieved the Items based on the selected group header. (This data is transfered from the ItemCommand event handler). The DataSource contains now 34 entries. 4 just to build the groups, and 30 detail entries for the group to expand.
7.) The ItemCreated and ItemDataBound event handler gets called.

Result:
The page now displays 3 Groups, the second with an expanded image button, but no items in the group. The paging bar contains figures for the three pages. Now I click on the second page, back to the first page.
After that, the first page is displayed as expected: The first and second Groups are collapsed, the third is openned and displays the items.

When now another group (say the second) is openned, the same happens: The first group is initial collapsed, the second expanded, but no items in it. After using paging, the page looks like expected.

Could you please help me to determine the issue, why group items are displayed only after a paging event? Is there some call missing?

Following is some Code from the ItemCommand event handler:

    
            if (e.CommandName == RadGrid.ExpandCollapseCommandName) 
        
                        { 
        
                            GridGroupHeaderItem groupHeaderItem = (GridGroupHeaderItem) e.Item; 
        
                            GridItem[] groupHeaderItems = grid.MasterTableView.GetItems(GridItemType.GroupHeader);  
        
                            // collapse all group header items currently on the page to support a "single open group" effect  
        
                            foreach (GridGroupHeaderItem grpHeaderItem in groupHeaderItems) 
        
                            { 
        
                                grpHeaderItem.Expanded = false;  
        
                            } 
        
                            // When "Expand" is clicked, the expanded state is set to false. Therefore, the division from this group header  
        
                            // needs to be read. When "Collapse" is clicked, the state is assigned "true"  
        
                            if (!groupHeaderItem.Expanded) 
        
                            { 
        
                                string currentDivision = this.GetDivisionFromGroupHeader(groupHeaderItem); 
        
                                new ObjectLifecycleHelper(this.Page, this.ViewState).SetCurrentSelectedGridDivision(currentDivision); 
        
                                groupHeaderItem.Expanded = true; 
        
                            } 
        
                            if (!grid.AllowPaging) 
        
                            { 
        
                                grid.AllowPaging = true; 
        
                                grid.PageSize = 15;  
        
                            } 
        
                            // rebind in each case, because otherwise the Expanded/Collapsed state is not changed by the view  
        
                            grid.Rebind();

Thanks for your support!

Sincereley,
