re: Binding a datasource to Chart

[Melissa]

I have a SQLDataSource that is returning the name of a column and the count. How can I bind the chart to a this datasource?

For example the data source will return
A 5
B 6
C 7

Hi Melissa,

Thanks for using Syncfusion products.

Here is the sample, which explains:
1. Connecting SqlDataBase with Chart using ConnectionString.
2. Object for ChartDataBindModel is created to access the DataTable.
3. Assigning fields to X and Y Axis.
4. Setting the labels.

And then appearance can be changed as you like.

I hope this sample will help you.

Let me know if you have any more queries.

Thanks,
Sureshbabu

That's doing everything in the code behind. Is it possible to bind to the chart using a SqlDatasource:

< a s p:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:connStr %>"
SelectCommand="spQ_MarketingCounts" SelectCommandType="StoredProcedure">

I still want to know if I can bind directly to a SQL Datasource, but I tried to bind using the way in the zip file and that doesn't work either. It seems as if it is pulling the values for the x series, but I can only see one and a half of them and there is no data being displayed in the column.

I've attached the code behind. The stored procedure spQ_MarketingCounts returns 2 columns- MarketingSource which has a list of sources for marketing and MarketingCounts which is the count for each source.

I figured out what I was doing wrong with the datasource. I wasn't selecting an ID and binding to it and it couldn't bind to the text.

Hi Melissa,

Thanks for using Syncfusion products.

I am able to reproduce this issue.

‘ChartValueType’ property set to any one of Custom, Double, DateTime, Logarithmic.

To work with string datatype, you can have the ChartValueType property set to Custom. This property helps in implementing user-defined datatypes.

Please take a look at the sample. Let me know if this helps.

Thanks,
Sureshbabu
