displaying tiny items without specific dates

Hi all,

I have C# class called EventHandler that looks like this. StartTime and EndTime both represent the number of seconds since the start of its "parent", which is basically just a list of Events.

public class EventHandler

{

public Event Event;

public float StartTime => Event.StartTime;

public float EndTime => Event.EndTime;

}

I'm trying to use RadGanttView to display the parent, (i.e. a List<Event>), but since StartTime and EndTime are both relative and don't have specific dates, I'm not sure where to begin. Values are both also typically below 5 seconds. Can anyone point me in the right direction?

Thanks in advance!

Cannot prevent user from entering the footer when document is protected

Create new Word-inspired project. Add the event handler below:

private void radRichTextEditor1_CommandExecuting(object sender, CommandExecutingEventArgs e)

{

if (e.Command is EditFooterCommand)

{

e.Cancel = true;

}

If document is not protected then user cannot enter the footer, either by menu or by double-click. If the document is protected (menu Review > button Protect Document) the user cannot edit the footer (as document is protected), nor can they enter it by menu (Insert > Footer), but they can still enter it by double-click. Is there a way to prevent them even from entering the footer by double-click when the document is protected?

Drag&Drop cannot work under the column sorting

Hello,

My gridview is in bound mode. I reorder the rows by drag & drop. I'm inspired by this telerik github demo:

https://github.com/telerik/winforms-sdk/tree/master/GridView/BoundGridReorderRows/GridViewRowsReorderBoundModeVB

I change the order of data source in order to reorder the rows by drag & drop. It worked well.

But if a column is sorted, any drag & drop cannot be toke into account. And then if I canceled a column sorting, the order synchronize well by drag & drop.

I wonder the column sorting maybe changed the order of child rows, not the order of rows, but then I change the order of rows (data source) by drag & drop, the order of child rows stays put strangely. So that's why there is no reordering affecting the display.

What happens between child rows and rows when I cancel the column sorting ?

What is the way out of this situation? I would like drag & drop has higher priority than column sorting/grouping.

Thank you by advance.

RadTreeView ContextMenu for certain nodes only

Hello,

I am wondering if it is possible to set a RadContextMenu for certain nodes when creating them programmatically.

For example, my tree will look something like this:

[MAIN NODE]

[Child1]

[Child2]

[MAIN NODE 2]

[Child1]

[Child2]

Would it be possible to have a RadContextMenu only for the parent node, and then a separate RadContextMenu for all the Child nodes?

Cannot select the entire row

Dear all,

After setting the selectionmode attribute to CellSelect in RadGridView, look at the photos below.

Click on the area in the red circle and the back cell row becomes highlighted in orange. However, the inner part of the circle does not change color.

This is not a whole row selection, I need a whole row selection

Is that possible?

What should I do?

Best wishes

Autocomplete gridViewComboBoxColumn: Suggestion getting appended to input incorrectly

I have a GridViewComboBoxColumn whose autocomplete behavior is undesired upon first cell click. Users are entering in a value, but when they first try to do something their input isn't properly appending to what they type and instead appends the first suggestion entirely onto their input. Please see UndesiredBehavior.gif.

Strangely enough, if they delete everything in the cell or change it and go back to it later on, then the behavior is desired: suggestions are being appended properly to what their input is. Please see DesiredBehavior.gif.

I am having a work around right now by instructing users to CTRL + A upon first entering into the cell and then deleting whatever is appended to their first key stroke, and then typing again, but I get complaints from users that they shouldn't have to do this.

Here is my code. Any suggestions?

         private void radGridViewDetail_CellEditorInitialized(object sender, GridViewCellEventArgs e)

        {



            if (e.ActiveEditor is RadDropDownListEditor)

            {

                //RadDropDownListEditor editor = (RadDropDownListEditor)e.ActiveEditor;

                RadDropDownListEditor editor = this.radGridViewDetail.ActiveEditor as RadDropDownListEditor;

                if (editor != null)

                {

                    RadDropDownListEditorElement element = (RadDropDownListEditorElement)editor.EditorElement;

                    element.AutoCompleteSuggest.DropDownList.SelectAllText();

                    element.AutoCompleteSuggest.DropDownList.DropDownSizingMode = SizingMode.UpDownAndRightBottom; // This does not work

                    element.ArrowButton.Visibility = Telerik.WinControls.ElementVisibility.Collapsed; // This works

                    element.AutoCompleteMode = AutoCompleteMode.SuggestAppend;

                    element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(275, 100);

                    element.AutoCompleteSuggest.DropDownList.MaxLength = 30;    

                switch (radGridViewDetail.CurrentColumn.Name)

                    {

                        case "CO":

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(100, 100);

                            element.AutoCompleteDataSource = companyCodeTable;

                            element.AutoCompleteDisplayMember = "COMP_CODE";

                            element.AutoCompleteValueMember = "COMP_CODE";

                            element.DropDownWidth = 200;

                            break;

                        case "CC":

                            int minimumWidth = int.Parse(costCenterTable.Rows[0]["MAX_LEN"].ToString()) * 8;

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(minimumWidth, 100);

                            element.AutoCompleteDataSource = costCenterTable;

                            element.DisplayMember = "ADDRESS";

                            element.ValueMember = "COST_CENTER";

                            element.AutoCompleteDisplayMember = "ADDRESS";

                            element.AutoCompleteValueMember = "COST_CENTER";

                            break;

                        case "Acct":

                            element.AutoCompleteSuggest.DropDownList.DropDownMinSize = new Size(275, 100);

                            element.AutoCompleteDataSource = glMajorTable;

                            element.DisplayMember = "ACCT_DESC";

                            element.ValueMember = "GLMAJOR";

                            element.AutoCompleteDisplayMember = "ACCT_DESC";

                            element.AutoCompleteValueMember = "GLMAJOR";

                            break;

                    }

                }

            }

        }
