I am using mulitple uploader, and need to get the file size at client side when user selects the file.
Is there any direct method or property to get size?
For now I am using the below code, but it is not working in IE

function selectedFile(sender, eventArgs) {
   var inputs = sender.getFileInputs();
   for (i = 0; i < inputs.length; i++) {
                    if (navigator.appName == "Netscape") {
                        size = inputs[i].files[0].fileSize;
                    }
   else if (navigator.appName == "Microsoft Internet Explorer") {
                        var filepath = inputs[i].value;
                        var SizeINIE = User_book.GetFileSize(filepath);     //This always returns 0 as the file will not be existing on server
                        if (SizeINIE != null) {
                            alert(SizeINIE.value);
                            size = SizeINIE.value;
                        }
                    }
}
Can anyone provide me solution for this ASAP?

Update ComboBox on client side

Hi,
I try to find a way to update the RadComboBox on client-side with an existing JavaScript array.

To lower the number of server requests we introduced a JavaScript file where we created arrays of countries, states and cities. Those elements won't change so a server request is not necessary. Now we'd like to use the RadComboBox for selecting the country, state and city. However I haven't found an easy way to do this.

We have:
- ASPX file with 3 RadComboBoxes for country, state and city
- JavaScript file with array of countries, states and cities

When the user selects a country, a javascript method should choose the correct state array and fill the state combo box with the possible items. Same for the state and city.

Does anyone have an idea if and how we can do this?

Thanks,
Hilmar

I am using the RadDock control on a client website page where the decorator is also used. The Decorator has the capability to turn off the feature for certain control types. Is there any way to turn off the Decorator for a RadDockZone/RadDock?

Thanks in advance!

Add new record accesskey?

My user has asked to add the ability to hit ctrl+a to run the Add New Record link on the grid. How can I provide this capability?

On a HRef html attribute, I would simply add a accesskey setting. How can I do this in the RadGrid?

Thanks for your help.

a Datatable named '' already belongs to this dataset

"a Datatable named 'table' already belongs to this dataset" is the error I am getting in a message box on my page. Here is the scenario of what is going on. I am saving the users grouped columns in my database. Upon reentering the page I pull from the database and regroup the grid using the stored values. Example of stored value: Balance Type|balance_type - First item is the name I use to display and the second is the actual field name that we want to group on. This works beautifully. They can save this and renter the grid and the settings is there. BUT!!! When the user selects to change the grid page size is when it generates the above error. I cannot determine where this is happening or why.

I am using needdatasource to bind my data from the SQL server and settting the grids settings after I populate the grid. I only get the settings from the database on the first load of the page because I don't want to stomp on the users changes every time they do something that might cause a postback to the page, that would be annoying.

So any ideas on what this is or why it is happening would be greatly appreciated.

What has changed to the height recently?

Hi,

I've just been alerted by a user that the latest version of the RadTreeView is now rendering extra height on the page - using the Black skin.

If I set the row height to 20 px I seem to end up with an extra 1px border being added. Interestingly when I do a mouse over the border for that row collapses and the row position moves up and to the left.

Please let me know what CSS hack I can apply to remove this behaviour. I've played around with the CSS tools in Chrome but couldn't find the problem..

Regards,

Jon

Change row view on row drag started?

Is it possible to change the view of the row when you drag it? By default you get to see a full floating row when you start to drag it. I would like to change this to an icon, basically the way Windows Explorer works when you drag a row from the details view.

I'm looking at the row drag started client side event to achieve this but not sure if that is correct or if indeed this is possible?

Dynamically created controls disappear or multiply on postback

Hi There,

I'm trying to add some extra GridTemplateColumns on my Page_Init using my own custom template class. When the page loads the first time, everything is fine and dandy. Yet after a postback from a filter or paging command, things go horribly wrong. More specifically, the extra columns that I i'm adding on Page_Init remain, but for every postback, an extra set of blank columns are added to the grid. My initial thought was to just wrap my Page_Init inside a if(!isPostBack) statement, but then no extra columns show at all after a postback. Please help!

Here's my Page_Init:

    
            protected void Page_Init(object sender, EventArgs e) 
        
                { 
        
                    ListBuilderTableAdapters.listsTableAdapter listAdapter = new ListBuilderTableAdapters.listsTableAdapter(); 
        
                    ListBuilder.listsDataTable dt = listAdapter.GetActive(); 
        
                    foreach (ListBuilder.listsRow dr in dt.Rows) 
        
                    { 
        
                        GridTemplateColumn gtc = new GridTemplateColumn(); 
        
                        gtc.HeaderText = dr.list_name; 
        
                        gtc.ItemTemplate = new MailingListTemplate(dr.list_name, dr.id); 
        
                        mlRadGrid.MasterTableView.Columns.Add(gtc); 
        
                    } 
        
                }

... and my custom template looks like this.

    
            public class MailingListTemplate : ITemplate 
        
                { 
        
                    protected string Text; 
        
                    protected int listID; 
        
                    public MailingListTemplate(string Text, int listID) 
        
                    { 
        
                        this.listID = listID; 
        
                        this.Text = Text; 
        
                    } 
        
                    public void InstantiateIn(Control container) 
        
                    { 
        
                        HiddenField hf = new HiddenField(); 
        
                        hf.Value = listID.ToString(); 
        
                        CheckBox cb = new CheckBox(); 
        
                        container.Controls.Add(hf); 
        
                        container.Controls.Add(cb); 
        
                    } 
        
                }

Also, my NeedDataSource uses the same datasource that I bind to on my Page_Load:

    
            protected void mlRadGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e) 
        
                { 
        
                        mlRadGrid.DataSource = recipientAdapter.GetUnique(); 
        
                }
