Can't clear value using contextMenu for dateTime column with timePicker editor

[Shlomo Pleban]

Hi,

I defined in two different grids two DateTimeColumn with timePicker editor . In the first column I have in the column ContextMenu the clear value option while in the other column I don't. 
What I am trying to do is letting the user clear the time cell after he filled it by mistake (if he prefers to leave it empty).
Let me know what I am doing wrong .... is it better way to do this ?

// with clear value option
  var timeOnlyColumn = new GridViewDateTimeColumn
            {
                HeaderText = "Time in",
                Name = Data.cJobCardData.JobCardColumns.DateTimeIn,
                FieldName = Data.cJobCardData.JobCardColumns.DateTimeIn,
                Format = DateTimePickerFormat.Time,
                EditorType = GridViewDateTimeEditorType.TimePicker,
                FormatString = "{0: h:mm tt}",
                TextAlignment = ContentAlignment.MiddleCenter,
                Width = colWidth
            };
// No clear value option
    var dateColumnIn = new GridViewDateTimeColumn
            {
                HeaderText = "Date Time In",
                Name = Data.cJobCardData.JobCardColumns.DateTimeIn,
                FieldName = Data.cJobCardData.JobCardColumns.DateTimeIn,
                Format = DateTimePickerFormat.Long,
                EditorType = GridViewDateTimeEditorType.TimePicker,
                FormatString = "{0: M/d/yyyy h:mm tt}",
                TextAlignment = ContentAlignment.MiddleCenter,
                Width = colWidth
            };

Hi Shlomo,

Thank you for writing.

The column's setup does not have effect of the context menu options - check out the attached project. I would suggest that you revise your code for handlers of the ContextMenuOpening event and to make sure that you are not explicitly hiding the clear menu item.

If you continue experiencing the same issue, please get back to me with a sample where it can be reproduced and I will look into it for you.

I hope that you find this information useful.

Hi,

Thanks for the response.

I didn't change anything in the code , but know all works fine ...

this is how I manage the context menu event.

private void oeGrid_ContextMenuOpening(object sender, Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)
       {
           var isDateTime = ((RadGridView) sender).CurrentColumn as GridViewDateTimeColumn;
           for (int i = 0; i < e.ContextMenu.Items.Count; i++)
           {
               if ((e.ContextMenu.Items[i].Text == "Copy") ||
                   (e.ContextMenu.Items[i].Text == "Paste") ||
                   (e.ContextMenu.Items[i].Text == "Pinned state") ||
                   ((e.ContextMenu.Items[i].Text == "Clear Value") && (isDateTime == null)) ||
                   (e.ContextMenu.Items[i].Text == "Conditional Formatting") ||
                   (e.ContextMenu.Items[i].Text == "Column Chooser") ||
                   (e.ContextMenu.Items[i].Text == "Hide Column")
                   )
               {
                   // hide the Conditional Formatting option from the header row context menu
                   e.ContextMenu.Items[i].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
                   // hide the separator below the CF option
                   //e.ContextMenu.Items[i + 1].Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
               }
           }
       }

Do you suggest to change it ?

Hello Amitay,

This setup seems to be correct and I am not able to determine what cased this issue as I was not able to reproduce it.

If you continue experiencing this issue, please get back to me with a sample where it can be reproduced and I will be glad to help you with it.

The problem was that I was in a row edit mode, and then I couldn't clear the cell. 
Once I moved to a new row , I could use the "Clear" option.
