Hi,

How do I specify what I want to be the tootip for an unbound RadHTMLChart in code (VB)?
the code works but shows the Y value (tDays) in the tootip, I need it to show the Name field (Dept)

see code below:

                    Dim DeptSum = (From d In EmpData Group d By Dept = d.Department Into Group
                                   Select Dept, tDays = Group.Sum(Function(d) d.Days)).ToList

                    Dim PieChartDays As New PieSeries
                    Dim PieSlice As PieSeriesItem

                        For Each DP In DeptSum
                            PieSlice = New PieSeriesItem
                            PieSlice.Name = DP.Dept
                            PieSlice.Y = DP.Tdays
                            PieChartDays.SeriesItems.Add(PieSlice)
                        Next

Hello Developers!

I am using Telerik Radgrid with Excel-like filters for creating my data grids. One issue I face is I cannot filter with symbol '?' or any word starting with '?' like '?check'. It immediately redirects to 500 internal error. If the symbol comes after any other character, the filter works fine, like 'o?c'.

I use RadGrid with DB source and autopopulate columns according to datasource. My filters are Excel-like filters.

I can replicate the same issue in your demo webpage for Excel-like filters too.

Placed screenshots for reference.

Could you let me know what can be done for this? It is absolutely important for me to be able to filter with '?'

Thanks and Regards

Hi Telerik Community,

I have a question which is a little difficult to explain, that is why I attached an image to make it more clear.
I have multiple data points, and each data point has a Pitch attribute associated with it, this Pitch measurement unit is Degrees.

Using the Telerik Chart framework, is it possible to plot each data point at its associated degree angle value and then plot the next data point in relation to the previous. Essentially what we need to do is visually show a profile that is mathematically accurate. I have been able to successfully and accurately achieve this on paper using a protractor but want to digitally achieve this using the Telerik Chart.

Each data point also has a depth value which needs to be shown visually in relation to its associated pitch data point, this will give us the ground elevation relative to the pitch data point.

Would appreciate some guidance on this.

Kind Regards.

DateTimeOffset and RadGrid.  Column does not show when this datatype is in resultset.

I have a dataTable with this datatype (DateTimeOffset) and this is the only column not showing.

I autogenerate the columns in the grid.

A workaround for now is to cast that column to datetime, or some other type in my SQL statement that generates the results.  Just curious if this is something that is being worked on or known about?

I have a radgrid set to a datatable.  Columns of type DateTimeOffset are hidden.

Why is this?

While following this tutorial to make my RadGrid stack columns vertically on a mobile device, I'm experiencing table width issues. 

In these screenshots, you can see that when I disable the element.style "width: 100%", the table renders as expected.  When it's enabled, the cells are all crammed in a narrow width.

So far, I've been unable to determine how to mimic this disabling in my CSS. 

Any ideas how to resolve?

Hi Team,

I have an issue with RadCombobox.
Currently we are using Telerik Version - 2015.3.1111.35 and Upgraded .NetFramework 3.5 to .NetFramework 4.8.

Tested in IE,edge and chrome - Not working.

Radcombobox dropdown click events are not firing after apppool changed to 4.0 for the first postback and 

It works for other controls in further postbacks.

Can anyone please help on this?

I'm creating a RadGrid dynamically and inserting a RadGrid into it.

When I change the RadGrid page, it disappears. How to keep the RadPageView content through Postback?

Besides that, none of RadGrid events are fired when the page changes.
