                                        <ItemTemplate>         
                                            <asp:DropDownList runat="server" ID="ddlApplicationStatus">         
                                            </asp:DropDownList>         
                                        </ItemTemplate>         
                                    </telerik:GridTemplateColumn>         
                                </Columns>         
                            </MasterTableView>         
                        </telerik:RadGrid> 
            
            
            
                    

Questions:

1. Should i use this gridtemplatecolumn or a GridDropDownColumn? I need to show a dropdown box in the grid which is in non -Editable mode.

2. How to fix this error?

Displaying Heirarchical Data in one row

I have a rad grid that displays in the following manner. What I am trying to accomplish to is if you see the columns with the heading(s) Name, LegName, MedicalConditions, DateofBirth and id displays as two rows, as it normally would, but what I would like to do is to have all that data display in ONE Row because it all belongs to one registration. If you look at the two images, image one is how the data comes out of the DB normally. Image two is how I would like to be. Please keep in mind that this is a small example and I actually have more fields than just this, so I am looking for something extensible. Thanks for your help!

radgrid scolling

Hello,

I have a radgrid that is paged and i have enabled scrolling, with 3 frozen columns.

I have three problems:
1) I would like to disable vertical scrolling. The user of my grid can set the page size to a number of rows and I would like the proper number of rows to be shown, without vertical scrolling. Can this be done?
2) It seems that the column widths are not scrolled at the same time as the columns are when using horizontal scrolling. By this I mean that when columns are scrolled, the size that they will take is the size of the original column that was showing in that spot before the scrolling took place. This does not look good and reduces the amount of data I can show in the grid at the same time.
3) As soon as I enabled horizontal scrolling, a number of columns on the right are missing and can't be scrolled to. If I disabled horizontal scrolling then they reappear and I can scroll to them using Internet Explorer's horizontal scroll bar.

An alternative for me would be to use the default IE scrolling, which fixes problems #1,#2 and #3, but this prevents me from freezing some columns and also the grid displays a vertical line in middle of the column that is at the right of the window.

Regards,

Sylvain

[Solved] how to determine when mouse has left the RadMenu

Is there an easy way to determine when the mouse has completely left the menu? The MouseOut event gets fired when moving from one menu item to the next, so the mouse may or may not have completely left the menu. How can I determine for sure that the mouse isn't over the menu, or any child menus?

Thanks,
Brian

RadDateInput SelectedDate='<%#DateTime.Now%>' does not work

Here's the line of code:

    
            <telerik:RadDateInput Label="Order Date:" width="700" ID="RadDateInput1" 

            DateFormat="MM/dd/yy" ForeColor="GrayText" 

            SelectedDate='<%#DateTime.Now%>' 

            runat=server />

When the control is rendered to the page. The DateInput is empty. I would expect it to be today's date.

Ideas?

Telerik.Charting.Styles.StyleLabel exists in both ...

Hello,
I got an exception with Q3 2009 Chart Control, the exception is
The type 'Telerik.Charting.Styles.StyleLabel' exists in both c:\...\...\...\Telerik.Charting.DLL

I have cleaned the asp.net temp folders but the problem persisted, on the machine there is no Telerik Reporting installed.

This happens on two development machines so it is not a localized case.

What could the cause be, and what might the solution be.

Thanks,
Martin
