Hi, I got an issue with the RadMaskedEditBox with standard phone mask (999) 000-0000. It works well when we enter only digits, but when we hit the keys like 123123-1234, the '-' skips the next character so I got text like this "(123) 123-_123". I'm not really familiar with telerik controls and I tried to find some way to avoid this without success. So is there a property or something else to avoid this problem or is there a real issue with the control itself. 

Thank you very much.

Hi Support,

I change my export to excel function to be able to have xlsx format instead of xls. So I change my ExportToExcelML to use GridViewSpreadExport function.

Everything works properly except the group column start in column B instead of column A. My users prefer when the data start in column A. You can see the difference between the old and the new format.

Is it possible that the group column start in column A like it was before?

Regards,

Nadia

Hopefully the attached screenshot will show the issue I am having.  It is intermittent but when I start typing on a multicolumn within a grid (and I think I have seen this with the stand alone multicolumn as well), the drop down pops but the scroll bar is initialized at the bottom of the list.  When this occurs, I am also unable to use my up/down arrow keys to navigate the drop down list so it is quite annoying.

 

This is on 2016 Q1.

Hello,

1. I added a grouping expression to my RadGridView, but the GridViewCheckBoxColumns no longer automatically become checked when all of the child rows in each group for that column are checked. How can I regain this functionality?

2. Also, is it possible to add header checkboxes that only apply to the groups? I have my GridViewCheckBoxColumns that apply to the entire column, but what if I just want to check/uncheck all the rows in a particular group?

Thanks!

I have a radgridview that is databound to a llblgen entity collection (implements IListSource) . One property of the actual databound object (entity) is a nulalble int. This property is set by a GridViewComboBoxColumn. When a new entity is added to the llblgen entity collection after the llblgen entity collection is databound to the radgridview the new row is automatically added to the radgridview but when the user changes the nullable property a NullReferenceException occurs:

Good day all

 

I just started playing around with the GantView in an existing Winforms application.

In general All seems to be working nicely, but I have 1 serious issue I cannot seem to get around.

 

On the context menu, when I am over a link, and select delete, It deletes the Parent/Child/sibling item. I have checked the forums and googled it , but can not find a way so far to simply just delete the link, and not any items.

 

Any links/samples/advice on how this can be achieved would be appreciated.

 

Regards

 

Marius

Hello 

I would like to remove the top and bottom border of each ribbon group at run time for a cleaner look. Have tried this in the form constructor with no success. Any ideas?

Dim myRibbonBarTab As RibbonTab = CType(Me.RadRibbonBar1.CommandTabs(0), RibbonTab)

For Each group As RadRibbonBarGroup In myRibbonBarTab.Items
        group.GroupBorder.BoxStyle = BorderBoxStyle.FourBorders
        group.GroupBorder.TopWidth = 0
        group.GroupBorder.BottomWidth = 0
Next

 

Thanks for any tips that point me in the right direction.

Robert

Hi,

I am looking to update our grids to have the "expanded information" details panel available for rows in a grid similar to the example you have at http://www.telerik.com/help/winforms/gridview-overview.html but I am struggling to find the sample code or documentation for achieving this.

Currently we have flat and hierarchical grids with master/detail records and we use standard table layout for parent and child rows everywhere and we are looking to have the "more info" look for the rows as shown in the sample.

Technically this isn't a master/detail relationship and is more like "further info" for the parent row, but if you could give me some pointers to the sample code/documentation on how to achieve this look and feel that would great.

Many thanks

 Mark.

Hi guys,

I'm hoping someone can lend me a hand in regards to the currentTimePointer functionality on the RadCalendar control.

The pointer only highlights the current day's current time, while I would like the line to extend across the whole week.

Basically, I'm trying to mimic Outlook when it comes to highlighting the current time.

The only accessible properties for the currentTimePointer are the Color and Width, so before I start diving in too deep, is there a fairly easy way to achieve the full length timePointer that I'm looking for?

Thanks,

Robert
