When I have same data for two or more y axis values, the lines on line graph overlap and I cannot identify which line is for what.

Attached is the picture to explain the scenario.

 

In the image 'Eastern Cape' and 'Western Cape chaekers' have same count = 3. we can see western cape orange line but red line is hidden behind the orange line.

 

Please suggest how can we show both lines.

The report parameter values are displayed in a div with list of options to select, instead of dropdown select list. Is there any option to change the format.

I  try to print reports without any gui (like ReportViewer or Print Dialog), to generate a lot of different documents from code behind. I would like that  users can coninue to work during this process.

I trying to do that  in this way:

 

Unfortunatly, while i'm printing my reports, apears  a  popup windows, like those one in atatched file.

How do I prevent x-axis labels on Reporting charts being forced to certain data types.

 

As you can see in my sample, the data table shows that the x-axis should be text, but the chart has forced the x-axis to be numeric and where it can't parse the value as a number it shows it as 0.

 

How can I make it show as text, like in the data table on the left?

Hello,

I was wondering if there is a way to set the text trimming of reporting textbox for my reports as we have for normal texblocks in wpf. Is there a way to do the same?

I would love to do something like: textbox.Texttrimming = TextTrimming.CharacterEllipsis

Thanks,

Hi,

I have created a crosstab report using crosstab wizard. I want the child rows to be collapsed by default. I can't find the grouped rows to hide in Group Explorer.

I have child rows upto 2 levels down. Both needs to be collapsed on first load.

Attached screenshot for reference.

Hi,
how it's possible create a chart with multiple line series?

for example in my db I have:

Date                Type        Value
01/01/2011      Red            8
01/01/2011      Yellow        12
01/01/2011      Green        9
02/01/2011      Red            6
02/01/2011      Yellow        9
02/01/2011      Green        7
03/01/2011      Red           5
03/01/2011      Yellow       11
03/01/2011      Green       13

I want create more line series how many are the type ( in my example 3), where the x-axis is Date and the y-axis Value.

I create a dataSource but whit series in property of the chart I can create only one line series.

thanks

Hello,

I am using a graph with a simple lineSeries (bound from a csvDataSource). 

When styling the label of each data point i can change the font and font-color. But i want to display a background behind the label.

I attached two screenshoots one form our kendo web project where the background of labels is working and one from the Telerik Reporting Designer.

I tried this demo's Provided by Telerik.

 

1. Download the telerik report Demos or open an existing working telerik report from Report Viewer.
2. Create ObjectDataSource with below model properties. In my case below Id property is Guid. Guid is not supporting in Telerik parameter data types, so we are using String datatype for Id.
          public class TestItem
       {
           public string Id { get; set; }
           public string Name { get; set; }
       }
3. Add a new Report Parameter with AvailableValues, select the ObjectDataSource created in above step. 
   • Display Member - Name
   • Value Member - Id
4. Check the Report Parameter attachment for quick review.
5. Create some mock data for ObjectDataSource created in Step2
   public IEnumerable<TestItem> GetTestItems()
           {
               var results = new List<TestItem>
               {
                   new TestItem { Id = Guid.NewGuid().ToString(), Name = "One" },
                   new TestItem { Id = Guid.NewGuid().ToString(), Name = "Two" },
                   new TestItem { Id = Guid.NewGuid().ToString(), Name = "Three" }
               };
               return results;
           }

   6. Run the sample from Report Viewer, click on Preview is throwing error

Above sample is working fine in Preview model. Only failing from Report Viewer.

Is this possible to run report using Report Viewer with Guid parameters?
