I was using telerik reporting to generate reports but they was some problems with rendering performance.  Due to large number of records and each record have several images. It takes too much time to render the report and when i scrolled up and down, it doesn't smooth. Is there any suggestion to improve the performance or decrease the render time. You can see the example report in an attach file.

Thank you.

Hi have a requirement to generate a grid of photos.  

I have managed to get the data in the shape where this can be grouped in a cross-tab.  The photos I need to bind to have a filename of {id}.jpg in a known folder.  I have created a user function that accepts the Fields.Id, retrieves this photo and returns an image (this is a technique I've used before successfully).

I have added a picturebox into the detail of the crosstab, but whenever I go to bind the "value" of the picturebox to the user function, Visual Studio crashes.  Stack trace below.  I suspect as this is in the detail it's trying to apply some aggregate to it.  Are there any workarounds to do this binding at runtime to get around this designer bug?

Is there a way to define multiple color palette for a same bar series and based on the parameters selected by user the graph shall automatically pick appropriate color palette for the series?

I am struggling to make our pie charts look good and be useful -- here are the two issues (somewhat related):

• The pie chart is connected to the same data source as a crosstab report, with the same groupings. Sometimes there are 20+ rows of data, and I want to display them all in the crosstab, but would like to only display the biggest 10 items on the pie chart, with the rest grouped under "Other." Is this possible?
• I would like to sort the order that wedges appear in the pie chart by size. Sorting by Field.MyNumber doesn't work because I actually want to sort on Sum(Field.MyNumber), but I get an error from the designer telling me I can't order by aggregate.

Are there solutions to these two items?

Ok, I have a report that is set to TextAlign = Justify.

I have a text box in the report that is set to TextAlign = Left. The text in the text box wraps to a second line.

When I run the report, the text is Justified, not aligned left, as specified for the text box.

Is this a bug, or does the TextAlign at the report level over-ride the alignment set at the text box level?

I've included screenshots that demonstrate this.

Thanks!

Hello,

I am using standalone report designer and I use this line of code to toggle culture based on parameter

Culture = IIf(Parameters.Language.Value = "en","en-US","fr-CA") in databinding

This works well for numbers currencies, and percentages on tabs, cross tabs etc but NOT charts.

Does charting library have a different initialization process? It seems that once chart is created, the culture remains static.

P.S. Culture of the Chart is (Default), setting value is not in bold font. 

Please advise

Thanks
