We are using a Tree View control with a context menu, and it doesn't seem to be working on OS 10.4/Safari 3.

I couldn't seem to find much information pertaining current versions of the Tree View control. Does anyone have any information on this subject?

To be specific, doing a Ctrl-Click doesn't trigger a menu to pop up. It just highlights the word(s).

Thanks,
Seth

how to get the filtered datasource

hi telerik,

I have some questions with the radgrid. I am using the grid with the AllowFilteringByColumn and paging properties enabled. It works as expected. My question is how can I get all the filtered rows if the grid has more than one page. I trie radGrid.Items, it shows only the items of the curent page.

i am looking forward to hear from you guys.

Image button overlap RadColorPicker

Hello Telerik :

I have a problem with a image button and a radcolorpicker.

The scenario is as follows :

The page has a radcombobox and a radcolorpicker and below it has a table with a label and an image button.

When I open the combobox works fine. But when I open the the radcolopicker the image button overlap the radcolorpicker.

I have been playing with z-index and with absolute position , but I don't get anything.

Any ideas ?

Edit on double-click demo error

I was looking at ideas for a project I'm currently working on - and I was trying out some stuff on your demo site. Specifically, the demo which shows how to edit on double-click. While doing so, I found a possible issue.

Here are the steps to recreate the issue:

1) Goto: http://www.telerik.com/DEMOS/ASPNET/Prometheus/Grid/Examples/DataEditing/EditOnDblClick/DefaultCS.aspx
2) Double click on a row to edit it.
3) Make a change to the data
4) Click on the pager to navigate to page 2
5) Click on the pager to navigate back to page 1
6) Double click on the same row to edit it - you will get a popup which asks Update Changes?
7) Click OK
8) Site error message displays.

I'm just guessing here, but it seems like using the pager to navigate doesnt trigger a check to see if the data has changed - but when you come back to the page and double-click - it knows the data was changed but that data is now inaccessible and the update fails.

[Solved] Show image directly from database

Hi all

I have a Databasetable with images in it.
Now I want to show those images in a GridTemplateColumn.
I want to show them directly from database, without first storing the pics on disk.
Is this possible? And how?

The code so far looks like this:

    
            <telerik:GridTemplateColumn UniqueName="ImageColumn">  
        
                <ItemTemplate> 
        
                    <img id="PlantImage" src='<%# Eval("Image") %>.jpg' alt=""/>  
        
                </ItemTemplate> 
        
                <HeaderStyle Width="100px" /> 
        
                <ItemStyle Width="240px" /> 
        
            </telerik:GridTemplateColumn>

But the images wont show up in the Grid.
I'm just stuck.

Thanks for your help.
Joffrey

FYI, this is the code I use to upload the images into the database. They are uploaded with radUpload. Code is mostly from a Telerik KB article.

    
            protected void btnUpload_Click(object sender, EventArgs e)  
        
                {  
        
                    mediaTypeTable = mediaType.GetAllMediaTypes();  
        
                    foreach (UploadedFile file in ruplMedia.UploadedFiles)  
        
                    {  
        
                        string extension = file.GetExtension().Remove(0,1);  
        
                        string imageType = file.ContentType;  
        
                        string name = file.GetNameWithoutExtension();  
        
                        //Set the mediaTypeId  
        
                        int mediaTypeId = 0;  
        
                        foreach (DataRow row in mediaTypeTable.Rows)  
        
                        {  
        
                            if (extension.Equals(row["Extension"].ToString()))  
        
                            {  
        
                                mediaTypeId = Convert.ToInt32(row["MediaTypeId"]);  
        
                                break;  
        
                            }  
        
                        }  
        
                        //ImageData  
        
                        byte[] binaryImageData = new byte[file.InputStream.Length];  
        
                        file.InputStream.Read(binaryImageData, 0, Convert.ToInt32(file.InputStream.Length));  
        
                        media.Insert(Convert.ToInt32(rcbPlant.SelectedValue), mediaTypeId, name, name, binaryImageData);  
        
                    }  
        
                }

Load on demand in template

Hi,

I've a control that contain a radcombobox in wich I've put a radmenu to make the selection. It's works great but now I want to add the "load on demand" option to my control to update de radmenu (the menu is filled with a SqlDataSource in the ascx).

When I try to use the "load on demand" I got this error :
"Script control 'mnu_test' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Nom du parametre;: scriptControl"

My code looks like :

    
            protected void list2_ItemsRequested(object sender, RadComboBoxItemsRequestedEventArgs e) 
        
                    { 
        
                        (list2.Items[0].FindControl("mnu_test") as RadMenu).Items.Clear(); 
        
                        list2.Items[0].FindControl("mnu_test").DataBind(); 
        
                    }

The update works in the code but the page does'nt update and the error is raised. Where's my error ?

Thx a lot !
