AJAX :: Populate Google Charts From Database Using JQuery
Nov 21, 2013
I am trying to implement google charts using sql database. I can not get the code to display charts on the client-side, as its currently blank page. I tried changing the str.append string but I still can not get the data to display on the client-side.
<%@ Page Title="" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true" CodeFile="Charts_07.aspx.cs" Inherits="Charts_07" %>
<asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" Runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" Runat="Server">
[Code] ....
database schema, I am using for this task.:
there are null cells in column cover and talks. -- could this be the reason why the chart rendering is falling?
INSERT INTO [dbo].[data]
([Id]
,[name]
,[data]
,[cover]
,[talk]
[Code] ....

I need to get the free Google charts working over SSL without any security errors. I am using c# and asp.net.As Google charts does not support SSL by default, I am looking for a robust method of using there charts but ensuring my user doesn't get any security warnings over their browser.ne thought was to use a handler to call the charts api and then generate the output my site needs.Similar to Pants are optional blog post. I haven't been able to get this example working at this stage.

protected void Page_Load(object sender, EventArgs e) {
Session["ID"] = "2";
string strConnString = ConfigurationManager.ConnectionStrings["BSDConnectionString"].ConnectionString;
var con = new SqlConnection(strConnString);
using (var sda = new SqlDataAdapter()) {
SqlCommand cmd = new SqlCommand();
[Code] .....
That was my code , now lets see what my problem is :
I am getting only two dates in a single row from sql to my asp.net webform and then bindng those dates in jQuery UI Datepicker. Now if i set session to 1 then date picker works well but if i put session = 2 , it shows the end date till 2020 which is wrong.
Below are the dates which are fetched from database and i have copied here....
When Session["ID"] = "1";
Start Date : 01/07/2014 00:00:00
End Date : 05/02/2015 00:00:00
When Session["ID"] = "2";
Start Date : 07/04/2015 00:00:00
End Date : 27/08/2016 00:00:00
I have set my mindate to startdate and maxdate to end date....
Also point of interest is that if i don't fetch values from database and use only List<string> in my web method then every thing works well. Like this :
[WebMethod]
public static List<string> GetDates() {
List<string> arr = new List<string>();
arr.Add("2014-07-01");
arr.Add("2015-02-05");
return arr;
}

I've got a web application I've built that makes various database calls to render some charts and datagrids for MI reporting purposes. I've got my database calls initiating on Page_Load within the .vb for each page. The site impersonates identity for database access. Page_Load returns a datatable and populates an HTML table inside an ASP:Repeater. Still with me? Well, everything works fine here. My problem is within the Default.aspx.vb Page_Load sub.
The Page_Load sub (in Default.aspx.vb) returns a datatable the same way as the others but instead of rendering the results to a repeater, the datatable is saved as Session("dt"). The saved session "dt" is then used to populate a couple of charts I've got on the home page(default.aspx):
<script
runat="server">
Public
Function buildXML(ByVal Product
As
String,
ByVal reportNameStr
As
String)

Dim clDB
