resize image

Based on your help file code, I would like to figure out how to create two thumbnails (one <=100 pixels wide and another <=700 pixels wide) and maintain the aspect ratio (constraint).

    
            string target = Server.MapPath("~/Images/Logos/");  
        
            Image.GetThumbnailImageAbort thumbnailImageAbortDelegate =  
        
            new Image.GetThumbnailImageAbort(ThumbnailCallback);  
        
            foreach (UploadedFile file in RadUpload1.UploadedFiles)  
        
            {  
        
            file.SaveAs(Path.Combine(target, file.GetName()));  
        
            using (Bitmap originalImage = new Bitmap(file.InputStream))  
        
            {  
        
            //You can implement additional logic to compute  
        
            // the width / height according your requirements  
        
            int width = originalImage.Width / 2;  
        
            int height = originalImage.Height / 2;  
        
            using (Image thumbnail =  
        
            originalImage.GetThumbnailImage(width, height, thumbnailImageAbortDelegate, IntPtr.Zero))  
        
            {  
        
            string thumbnailFileName = Path.Combine(target,  
        
            string.Format("{0}_thumb{1}", file.GetNameWithoutExtension(), file.GetExtension()));  
        
            thumbnail.Save(thumbnailFileName);  
        
            }

I am using this tooltip in content page.

        Me.UpdateToolTip(e.Value, e.UpdatePanel)
    End Sub
    Private Sub UpdateToolTip(ByVal elementID As String, ByVal panel As UpdatePanel)
        Dim ctrl As Control = Page.LoadControl("UserControlDetails.ascx")
        panel.ContentTemplateContainer.Controls.Add(ctrl)
        Dim UserDetails As UserControlDetails = DirectCast(ctrl, UserControlDetails)
        UserDetails.UserIDGUID = elementID
    End Sub
    Private Sub RadGridUsers_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles RadGridUsers.ItemDataBound
        If e.Item.ItemType = GridItemType.Item OrElse e.Item.ItemType = GridItemType.AlternatingItem Then
            Dim target As Control = e.Item.FindControl("targetControl")
            If Not [Object].Equals(target, Nothing) Then
                If Not [Object].Equals(Me.RadToolTipManager1, Nothing) Then
                    Dim currentRow As DataRowView = DirectCast(e.Item.DataItem, DataRowView)
                    Me.RadToolTipManager1.TargetControls.Add(target.ClientID, currentRow.Row("unique_identifier").ToString(), True)
                End If
            End If
        End If
    End Sub

Grid Grouping Column

Hi,
please can you help me with this, I am using RadGrid and I am grouping my column by code behind, the user select which column he want to group by and then press a command button I put in my page and by this button I used GroupByExpressions property to group my Grid, the question is: after the grid grouped a new column is added which is the grouping column and with each group header there is (+),(-) sign for collapse and expand the grouped rows, I put another button in my page to give the user the option to collapse or expand all the grouped rows and every time he press the button I used "GroupsDefaultExpanded" property to switch between True and False. is there any way to put the sign (+,- the collapse sign) in the header of the new added group column ?? and when the user press on it collapse or expand all the rows instead of using button for this, it will be more elegant and useful. by the way I tried to reach this new added grouping column but I could not.
Please advise me if I can do this or not.
Thanks

Grid Data Source Problem

HI Telerik team,

i would like to discuss the Grid data source problem with you (In case of MVC Framework).

i am supplying the list of objects to the grid as a data source. when the data source is a list of objects and object are single level then there is no prob. but when i pass the list and in list some of the objects are again a collection of objects then how to paint the grid.

example:

List

<Activity> list;

radGrid.DataSource = list;

and Activity class is something like this

public string CustomerName { get; set; }

public string AllocatedTo { get; set; }

public string Status { get; set; }

public UserInfoVO RaisedBy { get; set; }

Now RaisedBy is the object of class UserInfoVO which contain following properties
string firstName;
string LastName;
string phone;

now in this case in the view page i am using

<%

# Eval("Status ")%> to paint the field of the grid.

when it is for the primitive data type it display the value but how does it work for user defined classes... like i would like to print first name and phone no from UserInfoVo class.

thanks.

Regards,
Tej.

Removing "not-allow" cursor...

Is there any way to permanently remove the "not-allow" cursor?

That is, always having a pointer or hand cursor, no matter what happen to the tree or mouse action.

I'd like to add the ability to drag anything from outside and drop it on the treeview.

Can anybody give me some hints or pointers of how to do this?

Thanks.

[Solved] radCombobox Selected item display

I have a form with several radcomboboxes and a few buttons and textboxes. Each combobox has an empty Text Message that displays in gray italics. In the webform, you can select an item in the combobox using the dropdown UI or you can also click on an ad on the side of the page and the item is selected for you using javascript.

When the item is selected using javascript it displays the text for the item (as though it is actually selected), but the text is rendered with the Empty Item Text Style. So, it looks like the item was not selected.

Hope that makes sense. Please let me know if there is something I need to do to get the selected item to display properly.

[Solved] Use custom commands to trigger event on control

I'm just getting started with Telerik controls.

I would just like a bit of advice using the RadDock. I need to populate the RadDock with various user controls programatically which I can do great.

BUT - all of the RadDocks need an edit area which expands when a custom command is clicked, rather like the BBC site.

What would be the best way to go about creating this functionality? I was thinking that a regular CollapsiblePanelExtender would be good for that but how can i make it happen using the custom commands in the RadDock?

Any thoughts or pointers would be greatly appreciated!
