Hello,

Is there a way to have RadDataEntry controls read only? I know I can set Enabled =False for the whole RadDataEntry control but i"d like to limit it for some users while allow others to make changes. Also, users with read only access should be able to copy RadDataEntry controls values which is not the case for Enabled=False scenario.

Any clue is appreciated.

Thanks

Hello, 

how can I change the "GridViewPdfExport.PageSize Property" from Default 210 x 297 mm to Din A 4 Landscape 297 x 210 mm?

Namespace "Telerik.WinControls.Export" is imported.

Using PdftoExport is not an option because I need the header feature. 

I am using VB.Net.

Thanks in advance,

hi ,

I want my binding data source to update or refresh after adding a new record to the database.When I add one it won't update till closing and re-opening the form.

I would like the Ribbonbar to always appear collapsed even when I select some of the tabs on it.  I want to be able to expand it only when certian criteria are met.

So far I have been unable to get the ribbonbar to start off Collapsed, nor can I get it to remain collapsed.

Please Advise

Thanks

I have a RadSplitbutton with 6 subitems.    When I click on the arrow, I expect the dropdown menu to be displayed, instead it is first firing the click event of the button, then displaying the menu.  This is not what I wan to happen!

How to I prevent this from happening when trying to select the Arrow?

Thanks

Grid is cleared and then Loaded with data. User selects "new row" and the system puts them on a specific cell. User enters a value and TABS or ENTERS. Then does other tasks. User returns to the grid which is again cleared and then Loaded with data. The user selects "new row" and the system puts them on a specific cell, which is prepopulated with the previous value entered. 

>>> Would like not to have the new row cell pre-populated 

Steps:

1. Add a value to a cell (a) on a new grid row and commit it.

2. Perform other tasks on the form

3. Return to the Grid in (1) and open a new row. 

> The value from (1) is set as the default for the cell (a)

Although I clear the grid before repopulating, I haven't been able to remove this default (previous) value. 

Just before I Load the grid:  

Any ideas how to prevent it from pre-populating? 

Hi,

I'm working on a project where I need to display data in Telerik RadGridView.

One of the column is going to display icons (can be multiple, displayed horizontally). These icons will be provided from .resx file of the project.

I was exploring custom column, tried creating custom column with RadPanelElement assuming that I'll be able to add picturebox windows control to the RadPanelElement object like

protected override void SetContentCore(object value)
        {
            if (this.Value != null && this.Value != DBNull.Value)
            {
                //this.radProgressBarElement.Value1 = Convert.ToInt16(this.Value);
                //this.radImageList
                foreach(string strImgIndex in this.Value.ToString().Split(','))
                {
                    PictureBox pbIcon = new PictureBox();
                    switch (int.Parse(strImgIndex))
                    {
                        case 0:
                            pbIcon.Image = WindowsFormsApplication1.Properties.Resources.binoculars;
                            break;

                        case 1:
                            pbIcon.Image = WindowsFormsApplication1.Properties.Resources.open;
                            break;

                        case 2:
                            pbIcon.Image = WindowsFormsApplication1.Properties.Resources.printer;
                            break;
                    }

                    //this.radImageList.Controls.Add (NOT ABLE TO ADD CONTROLS DYNAMICALLY)
                    //pbIcon.Image = Image.
                }
            }

It didn't work as not able to add controls to RadPanelElement. Please provide a way out to achieve the required custom column.

Thanks & Regards

Hello,

I have a grid view with a cell containing either a TextBox which is ReanOnly or a ComboBox for which the user has to select a value.

The arrow button of ComboBox cell is only visible when user clicks on cell to edit it. Thus, the user does not know if he has to select or not a value

I'd like that the arrow button of ComboBox cell is always visible to indicate to user that a value has to be selected.

I've tried to set the visibility of arrow button in EditorRequired event but it has no effect.

        void QualityControlsEntryGridView_EditorRequired(object sender, EditorRequiredEventArgs e)
        {
            if (QualityControlsEntryGridView.Columns["Result"].IsCurrent)
            {
                if (QualityControlsEntryGridView.CurrentRow.Cells["ReferenceValueToType"].Value.ToString() != "")
                {
                    e.Editor = new RadTextBoxEditor();
                    e.EditorType = typeof(RadTextBoxEditor);
                }
                else
                {
                    e.Editor = new RadDropDownListEditor();
                    e.EditorType = typeof(RadDropDownListEditor);
                    RadDropDownListEditorElement editorElement = (RadDropDownListEditorElement)((RadDropDownListEditor)e.Editor).EditorElement;
                    editorElement.ArrowButton.Visibility = ElementVisibility.Visible;
                }
            }
        }

Hi all,

some time ago starting from some code I found here, I wrote a method to add a button in a dropdownlist (I have used a label with an image instead of a button), it seems to work fine but if I use it with a dropdownlist that is contained in a RadWizard or RadTreeView page, the button is shown only if that page is the selected page when the form is loaded, but is not shown when I click on a Tab move to the page that contains the dropdownlist.

I usually add call the method in the Load event of the form, but I've tried tu use other events with effects.

This is the method :

        public static void ButtonizeDropDown(RadDropDownList ddlistControl, EventHandler OnClick, out RadLabelElement btnElement) {
            btnElement = null;
            EventHandler onLabelElementClicked = (object s, EventArgs ea) => { ddlistControl.SelectedIndex = -1; };
            if (OnClick != null) onLabelElementClicked = (object s, EventArgs ea) => { OnClick(ddlistControl,ea); };
            ddlistControl.BeginInit();
            RadLabelElement lbl = new RadLabelElement();
            btnElement = lbl;
            lbl.Click += onLabelElementClicked;
            lbl.Margin = new Padding(0, 0, 0, 0);
            lbl.AutoSize = false;
            lbl.Text = "";
            lbl.Tag = ddlistControl;
            lbl.Image = new Bitmap(global::K2O.UI.Properties.Resources.Delete_Thin_BW_UltraLight_12);
            lbl.ImageAlignment = ContentAlignment.MiddleCenter;
            lbl.TextAlignment = ContentAlignment.MiddleCenter;
            lbl.TextImageRelation = TextImageRelation.Overlay;
            lbl.Alignment = ContentAlignment.MiddleCenter;
            ddlistControl.DropDownListElement.EditableElement.ShouldPaint = false;
            RadDropDownTextBoxElement textBoxElement = ddlistControl.DropDownListElement.EditableElement.TextBox;
            RadTextBoxItem textboxitem = textBoxElement.TextBoxItem;
            ddlistControl.DropDownListElement.EditableElement.TextBox.Children.Remove(textboxitem);
           
            lbl.Size = new System.Drawing.Size(textBoxElement.Size.Height, textBoxElement.Size.Height);
            StackLayoutElement stackPanel = new StackLayoutElement();
            stackPanel.Orientation = Orientation.Horizontal;
            stackPanel.Margin = new Padding(0, 0, 0, 0);
            stackPanel.Size = lbl.Size;
            stackPanel.Children.Add(lbl);
            DockLayoutPanel dockPanel = new DockLayoutPanel();
            dockPanel.Size = lbl.Size;
            dockPanel.Children.Add(stackPanel);
            dockPanel.Children.Add(textboxitem);
            DockLayoutPanel.SetDock(textboxitem, Dock.Right);
            DockLayoutPanel.SetDock(stackPanel, Dock.Left);
            ddlistControl.DropDownListElement.EditableElement.TextBox.Children.Add(dockPanel);
            if (ddlistControl.DropDownStyle == RadDropDownStyle.DropDownList) {
                textboxitem.ReadOnly = true;
                ddlistControl.DropDownListElement.EditableElement.TextBox.Visibility = ElementVisibility.Visible;
                ddlistControl.DropDownListElement.EditableElement.TextBox.Enabled = true;
                lbl.Enabled = true;
                lbl.Visibility = ElementVisibility.Visible;
            }
            //Per fare in modo che tutti gli elementi del controllo acquistino lo stesso stato (Enabled/Disabled) del controllo stesso;
            ddlistControl.Enabled = !ddlistControl.Enabled;
            ddlistControl.Invalidate();
            ddlistControl.Enabled = !ddlistControl.Enabled;
            ddlistControl.EndInit();
        }

can you please tell me what I must change to have it work in every page of a RadPageView or RadWizard ?

Thanks
