Questions on UI for WinForms Forum

I upgraded from 2009 Q2 SP1 to 2009 Q3 and have noticed some odd behavior with Autohide toolwindows that was not there before.

On the main MDI form, I have a toolwindow set as autohide. With the new release, I find that when I open a child MDI form, the autohidden toolwindow opens or animates as if I hovered over its tab. This did not use to occur. I only want animation when I hover over the tab.

On a child MDI form, I have a toolwindow set as pinned. When I hide it, hovering over the tabs does not do anything until I resize the main MDI form window. That action causes the tabs to animate normally. Again, this did not use to occur. I want animation anytime I hover over a tab.

Has anybody else experienced this?

More importantly, how can I get back the old (normal) behavior short of rolling back to Q2?

Hello muralitharan,

You use a very old edition of RadGridView. Please download and use the latest edition of RadControls for Winforms (Q3 2009). We have made many improvements and fixes in filtering.

For example:

    
            childnode = new RadTreeNode("child");

            childnode.MouseDown += new MouseEventHandler(node_MouseDown);

The code as above is work OK in RadControls for WinForm Q2 2009,but it'll occur error message when compile these codes for WinForm Q3 2009,

The error message show "Telerik.WinControls.UI.RadTreeNode' is not include the Definition of 'MouseDown'..."

This problem have led to some functions can't work of our software now.

MultiColumn Combobox Error

Hi,

I have a multicolumn comboBox, it worked properly for me till i selected a row from the grid.

After selecting the row and focusing on the textbox, whenever i press any key it gives the following exception. (See Attached File.)

I also tried it in your DEMOS of multicolumn comboBox and i received the same result.

It surely seems as a bug, i hope it will be removed in Q3.

Regards,

Onur

Overlapping Controls Parent/Child

I have a RadGridView control on a form which I need to place a RadButton over the top of. The RadGridView will be disabled in code using the enabled property based on a timer. Basically a timer will disable the grid and the refreshing aspect of it. The RadButton will then be made visiable and allow the user to re-enable the grid display and thus allowing data to update again.

The problem I am having is that the RadButton docks to the RadGridView Control meaning it becomes a child of the RadGridView control. This means when I disable the RadGridView the button also becomes disabled.

Do you have any idea how I can have the button overlapping the RadGridView Control without it becoming a child of the control?

Regards
Neil

ResourceUpdater improvement

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"]);
