Hello Telerik,

Currently, ResourceUpdater, which comes with RadControls WinForms, can update only one project file per application instance because it disables "Upgrade" button everytime it performs a project conversion (and it will never be enabled again).

I would like to ask you to add just one line to UpgradeForm.cs, which allows us to perform multiple conversions without re-starting the ResourceUpdater application over and over again:

    
            private void Browse_Click(object sender, EventArgs e) 
        
            { 
        
              // ... 
        
              if (dialog.ShowDialog() == DialogResult.OK) 
        
              { 
        
                this.ProjectFile.Text = dialog.FileName; 
        
                this.UpgradeButton.Enabled = true; // <--- this line 
        
              } 
        
            }

Please consider reflecting this change or something similar to the RadControls source tree, since I don't want to go through all the process of building the source code release, just to enable one button in the ResourceUpdater.

Thanks in advance,
Toshiyuki

RadRibbonBarButtonGroup Orientation

Hi,

I have some RadRibbonBarButtonGroup that I want to give Horizontal Orientation, everything seems to set fine, but then I close the designer or run the program and it returns to Vertical.
This wasn't an issue in previous versions, but I've just updated to Q3 2009 and this started.

ComboBox binding to Items Collection

Hello,

We are upgrading to the latest version of the WinForms components. I see there have been changes to the binding logic. I have a RadComboBox and I'm binding a list to it. If I create the combo dynamically and assign my list to the datasource property the Items collection is not bound (Items.Count = 0) until I assign the combo box to a container.

Is there a way to force this sooner without requiring a parent component? In this case our combo box is in a grid with an image associated with each item in the list so we are doing some initialization and need the items to be there for this.

Thanks,

-Gary

Here is some code to demonstrate the problem:

    
                public partial class Form1 : Form 
        
                { 
        
                    const string DISPLAY_FIELD = "Name"; 
        
                    const string VALUE_FIELD = "ID"; 
        
                    public Form1() 
        
                    { 
        
                        InitializeComponent(); 
        
                    } 
        
                    private void radButton2_Click(object sender, EventArgs e) 
        
                    { 
        
                        List<ComboItems> comboItems = new List<ComboItems>(3); 
        
                        comboItems.Add(new ComboItems("Red", 1)); 
        
                        comboItems.Add(new ComboItems("White", 2)); 
        
                        comboItems.Add(new ComboItems("Blue", 3)); 
        
                        RadComboBox rcb = new RadComboBox(); 
        
                        rcb.DisplayMember = DISPLAY_FIELD; 
        
                        rcb.ValueMember = VALUE_FIELD; 
        
                        rcb.DataSource = comboItems; 
        
                        // rcb.Items.Count == 0 at this point 
        
                        rcb.Parent = this; 
        
                        // now rcb.Items.Count == 3  
        
                    } 
        
                } 
        
                public class ComboItems 
        
                { 
        
                    public string Name { get; set; } 
        
                    public int ID { get; set; } 
        
                    public ComboItems(string displayMember, int valueMember) 
        
                    { 
        
                        Name = displayMember; 
        
                        ID = valueMember; 
        
                    } 
        
                }

grid grouping error

I am trying to make a multi row column that has two column header (groups) and 3 rows. In the first row, the first column has 2 columns under it and the second column has two columns as well. but in the third row the first column is blank (or atleast looks that way to the user), the second column has three columns where on column belongs to on parent and the other 2 belong to the other column

    
            +------------------------------------+----------------------------------------------------+     
        
            |               Name                 |                   Location                         |     
        
            +----------------+-------------------+--------------------------------+-------------------+     
        
            |     fname      |       lName       |           address 1            |    address 2      |
        
            +----------------+-------------------+---------------+----------------+-------------------+     
        
            |                |                   |     street    |      state     |     country       |

Is there a parent child relationship I am missing to get the second row under it's respected parent or is it another GridViewColumnGroup

    
            view.ColumnGroups.Add(new GridViewColumnGroup("Name"));  
        
            view.ColumnGroups.Add(new GridViewColumnGroup("Location"));  
        
            view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());  
        
            view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());  
        
            view.ColumnGroups[0].Rows[0].Columns.Add(radGridView1.Columns["fname"]);  
        
            view.ColumnGroups[0].Rows[0].Columns.Add(radGridView1.Columns["lName"]);  
        
            view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());  
        
            view.ColumnGroups[1].Rows.Add(new GridViewColumnGroupRow());  
        
            view.ColumnGroups[1].Rows[0].Columns.Add(radGridView1.Columns["address 1"]); 

            view.ColumnGroups[1].Rows[0].Columns.Add(radGridView1.Columns["address 2"]); 
        
            view.ColumnGroups[1].Rows[1].Columns.Add(radGridView1.Columns["street"]);

            view.ColumnGroups[1].Rows[1].Columns.Add(radGridView1.Columns["state"]); 

            view.ColumnGroups[1].Rows[1].Columns.Add(radGridView1.Columns["country"]);

[Solved] GridViewDateTimeColumn queries

Hello,

I have a few questions regarding the GridViewDateTimeColumn.

One, is there a way to set the range of dates that you can pick? Or perhaps a way to disable future dates?

Two, is there a way to create a TimePicker column?

Three, when editing an empty DateTime column it seems I have to make a selection, if i leave the selected date as it is (i.e. todays date) that date does not "stick" when I leave the column. The only way to select todays date it seems is to select another date first (using arrow keys) then today's date or to select the date in the actual date picker. Is there a way to make today's date "stick", if you will, without having to make an explicit selection?

Thank you
Johan

No Snap-to GridLine for Bottom of Text inside a RadComboBox

When I'm moving a RadComboBox up / down in the Designer, no horizontal snap-to grid line pops up when the bottom of the text inside the TextBox portion of the Control aligns with the bottom of at least a Label or RadLabel Control or the text inside at least a TextBox or RadTextBox if not other controls as well. The line only pops up when the bottom of the entire RadComboBox aligns with the above items.

ListBox Add Item as object (not RadItem)

the built-in windows forms listbox allows you to add items as objects, however the radlistbox forces you to add a listboxitem. why is that?

this is especially confusing because the SelectedItem property returns an object and NOT a RadItem.

I want to be able to add an object like I do for a regular listbox. can this be done?

RadColorDialog with Named Colors

Trying to use the RadColorDialog with only the web tab showing to select Named colors. Oddly after the "named" color is selected in the dialog, the SelectedColor is not a named color. Pick Blue then see what happens.

    
                        radColorDialog1.ColorDialogForm.ShowBasicColors = false; 
        
                        radColorDialog1.ColorDialogForm.ShowProfessionalColors = false; 
        
                        radColorDialog1.ColorDialogForm.ShowSystemColors = false; 
        
                        radColorDialog1.ColorDialogForm.ShowHEXColorValue = false; 
        
                        radColorDialog1.ColorDialogForm.AllowColorPickFromScreen = false; 
        
                        radColorDialog1.ShowDialog(); 
        
                        var color = radColorDialog1.SelectedColor; 
        
                        var blue = Color.FromName("Blue"); 
        
                        var areSame = color == blue ? "Same Color" : "Different Colors"; 
        
                        var isKnown = color.IsKnownColor ? "Yes named" : "Not named"; 
        
                        MessageBox.Show(string.Format("Color 1: {0} ({4})\nColor 2: {1} ({5})\n{2} : {3}", color, blue, areSame, isKnown, color.ToArgb(), blue.ToArgb()));

Blue != Blue, Same ARGB != Same ARGB, Is not a named color.

[Solved] Filtering multiple columns with or

I was wondering if the grid view do a complex or statement between multiple columns.. I basically want the following statement.

var_1 = 1234

Show me all rows where (column_1 contains var_1 ) or (column_2 contains var_1 ) or (column_3 contains var_1 ) or (column_4 contains var_1 )

So I can have 1 field that searches multiple columns... can this be done with the radGridView or does it have to be done server side? Any sample code would be greatly appreciated.
