I have just recently installed Telerik (10.0.16.2004) reporting running within visual stuido 2015.  

In the report designer I can draw any static controls such as a textbox and the report preview works fine, but the second I add a SqlDatasource to the project, the previewer quits working.  The datasource is correctly configured and returns data in the setup.

Please advise...

I have a report which has a table displaying data correlated by week, which has an issue I can't figure out - i'm guessing i have a setting wrong but nothing I've tried to change has seemed to fix it. Also wondering if spacing can be further adjusted. I've attached a file with examples of the output.

 The default is the previous four weeks of data, which renders fine (image one in attached). I would like wider bars on the graph,but I have the spacing slot count at 1 so if nothing else can be adjusted, we can live with it.

Image two shows only two weeks of data available, this is where I'd really like to see the columns closer, and the bars again a little wider. 

Image three is the real issue I need to solve. In this report, only one week of data is available. The bar renders correctly, but as you can see in the image, there are labels across the entire x axis, when there should be only one label for 2/6/2016. It appears the labels are for a year.

My settings for the x axis are:

Layout:

LabelPlacement - NextToAxis

MaxSize - empty

MinSize - empty

Size - empty

Title Placement - Centered

Misc:

LabelAngle - 45

LabelFormat - {0:d}

MajorTickMarkDisplayType - Cross

MinorTickMarkDisplayType - None

MultiLevelCategoryLabels - False

Scale - DateTime Scale

  BaseUnit - Auto

  CrossAxisPositions (Collection) - none set up

  LabelStep - 7

  LabelUnit - Days

  MajorStep - 7

  MajorUnit - Days

  Maximum - empty

  Minimum - empty

  MinorStep - 0

  MinorUnit - Auto

  PositionMode - OnTicks

  Reversed - False

  SpacingSlotCount - 1

Thanks for any help,

The problem is when am switching to arabic culture Leaving it with the default align (left) will be shown in the webpage as it’s right aligned(cuz it's arabic culture) but when exporting or printing u find it aligned to left.

and when changing the align of text to right will be shown in the webpage aligned to left and printed/exported aligned to right.
