Chart Control getting numbers from GridView, but just duplicates

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :ASP.Net

I have a gridview that I loop through to get the x and y values of the chart control, and upon the first execution of this code, it looks great.  But when the page posts back and it "refreshes" data, the original points on the chart control are still there, as well as the new values.

Is there any way to "delete" all data in the chart control to ensure this doesn't happen?  I can't seem to find any resources to help me out with this.

Thanks in advance. :)

GridView data to Chart Control


I have a GridView that is filled with databound data.  My problem is that I have a template field that uses the index + 1 for the gridview to give each record a unique number.  Then with this Gridview, with BoundFields and TemplateFields, I want to have this data to be the data for the chart control series.  How exactly is the best way to go about this?

Thanks in advance. :)

Using TemplateFields in the GridView Control

The GridView is composed of a set of fields that indicate what properties from the DataSource are to be included in the rendered output along with how the data will be displayed. The simplest field type is the BoundField, which displays a data value as text. Other field types display the data using alternate HTML elements. The CheckBoxField, for example, renders as a checkbox whose checked state depends on the value of a specified data field; the ImageField renders an image whose image source is based upon a specified data field. Hyperlinks and buttons whose state depends on an underlying data field value can be rendered using the HyperLinkField and ButtonField field types.

Reuse a gridview within calendar control


Hello, I have a calendar control that will have events displayed within each cell.

I want to use a pre formatted gridview and simply bind the gridview with a dataset dynamically and display it within the cell of the specified day.

Is there a way to do that or do I have to dynamically build a gridview for every day that there is an event? 

So here is the template gridview and datasource:

 <asp:SqlDataSource ID="sqlcalitemtemp" runat="server" 
        ConnectionString="<%$ ConnectionStrings:NNTrainingdbconnection %>" 
        SelectCommand="SELECT NN_Fire_Events.Start_Time, NN_Fire_Events.End_Time, tblNN_Fire_Cli
