Hello Telerik Team,

i need to create a WinForm that shows data in an chart and additionally in a table under the chart.

The attached picture shows an example of the data.

The x-axis has a calendary week as unit.

The width of the column and the width of the calendary week in the chart shall be the same

The intervall (week) of the chart shall be syncronised with the column of the table.

After showing the data in the WinForm it shall be exported into one picture.

How can i achieve the needed features?

Thank You very much for Your help.

Best Regards

Ingo

A toggle/Slider switch control would be a nice addition to the Telerik Winforms Controls Collection.

A lot of Windows 8.x and soon (10) applications use such controls and they have become familiar to everyone these days - but it seems there is no equivalent control in the WinForms Collection.

Hi,

I was wondering if we have the ability to set the aggregate column when have a grouping. When i put in a summary row it sets the aggregate the appropriate column, however I'd like to put it in the group header. The main reason behind this to show the user the sum without having to expand the row to see the summary row.

Attached is a screenshot of an example grid of what I'd like the data to show. You'll see each row has the group, then the aggregates get summed up to that level.

Does this make sense? Is it possible?

Thanks

Hi all,

 

I'm using grid view to display my data. All works well but all names which start with "US_TV" are ellipsis automatically but cell length is wide enough to display all content.

Don't know what's problem ????

 

Hi 

I want to draw a diagram similar to the one in the attached image.

It will be great if the names of vertical lines could be frozen to the top section of the diagram.

The user should not be able to modify the diagram.

 

I have a very simple grid - its blank.  No rows, no columns.  The grid control's name = gg

In Code I add one column:  GridViewTextBoxColumn() like this:

 

Dim myCol As GridViewDataColumn = Nothing

myCol = New GridViewTextBoxColumn()
myCol.DataType = GetType(String)
myCol.Name = "Test Texteditor"
myCol.FieldName = "TestText"

myCol.HeaderText = "TestText"
myCol.ReadOnly = False
myCol.IsVisible = True

gg.Columns.Add(myCol)

 

I have another method that creates a row for testing.

I've checked ReadOnly on:  Grid, Row, Column and Cell.  ALL are ReadOnly = False

but when I double-click on the cell - nothing happens.  No Text Editor nothing.  At first I thought, ok I'm creating this column dynamically so there must be some methods I'm supposed to hook into (AddHandler) and specifically I figured I'd need to hook into EditorRequired but there's no such method for a GridViewDataColumn() so I'm really stuck.

 

I'm 100% certain I'm doing something stupid and any help or nudge or shove in the correct direction would be very appreciated.

Thank you!

Hi

I want to clear the pivotgrid contents.

I am using LocalDataSourceProvider and providing datatable as itemsource.

If I set the LocalDataSourceProvider object to null, I get NullReference exception.

I have emptied the rows and columns, but the grid does not refresh.

Is there meanwhile a way to control the position of the axis crossing ? It's strictly fixed to an outside corner of the ChartArea ?

I found this old thread with an answer, may be things have changed meanwhile

https://www.telerik.com/forums/drawing-x-axis-on-chart-view-at-zero-when-negative-values-exist

RadChartView is such a rich thing, it's on wonder while such a basic feature as control the axis crossing is missing.

That means a 4 quadrant chart (going f.e. from -100 to +100 on both axis, with having the axis crossing at (0,0)) is strictly impossible ?

hi telerik

                foreach (GridViewDataRowInfo row in re_ItemregiView.Rows)
                {
                    //
                }

 

The gridview data sorted by clicking on the Gridview header. the data from the source above will have the same content but in a different order.

I want to get an ordered sequence of data on the source.
