AJAX :: Verify If Points Exists On Line Chart Control

May 7, 2015

This is my aspx code :

<asp:Chart ID="ChartAlertes" runat="server" Width="500px">
<Titles>
<asp:Title Text="Nombre d'alertes et leurs status en fonction des filtres renseignés"
BorderColor="Black" Alignment="TopCenter">
</asp:Title>
</Titles>

[code]...

I display 2 Points (2 columns) in the Chart Control and I change the color of the each Points with :

ChartAlertes.Series[0].Points[0].Color = System. Drawing. Color.Red;ChartAlertes.Series[0].Points[1].Color = System.Drawing.Color.DarkOrange;

But sometimes, I have only 1 Point to display or nothing at all on the Chart. So I'd like to check If there are some Points before to put the color of each Point.

For example :

if (ChartAlertes.Series[0].Empty == false)
{
//...
}

AJAX :: Line Chart Control - Display All Values On X Axis

Mar 6, 2013

I work with a tank of visual studio when I click to display the graph he shows not all points on the X axis

for example the table nbr_num_semaine_av contains values in order

(18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,52,1,2,3,4)

but the graph shows on the X axis only that 18, 38, 41

for (int k = 0; k < semaine.Count(); k++) {
Chart4.Series["Nombre de points terminés"].Points.AddXY(nbr_num_semaine_av[k], nbr_points_Termin[k]);
Chart4.Series["Nombre Total d'element"].Points.AddXY(nbr_num_semaine_av[k], nbr_element.Count());
}
Chart4.Series["Nombre de points terminés"].ChartType = SeriesChartType.Line;
Chart4.Series["Nombre Total d'element"].ChartType = SeriesChartType.Line;
Chart4.Series["Nombre de points terminés"].IsXValueIndexed = true;
Chart4.Visible = true;

C# - Verify That Email Domain Exists?

Jun 14, 2010

Does anyone check the domain of an email address as part of their verification steps? eg. Confirm that gmail.com exists if the user specified blah@gmail.com as their address.

I should note that in my webapp an existing user can forward invites to their friends. I have no need to verify those invites at all. Rather, I just want to warn my user if a typo etc. may be sending an invite to the wrong person. Is this even worthwhile to do?

Web Forms :: Verify Value Exists In Table For DDL?

Jun 30, 2010

How do I check if a value in the dropdownlist is in the table bound to the girdview?

Some fields bound to the gridview contain values that are not in the dropdownlist. I would like to check in the code behind whether the value is there and if not set the ddl selected value to "Select" with a value of "". If the value is there then set the selectedvalue to the value in the gridvidew.

Also, the ddl is nested inside an edit template.

Here's an example:

<form id="form1" runat="server">
<div>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Logs_ID"[code]....

AJAX :: Line Chart Not Working In IE?

May 7, 2015

 C#:

protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
LineGraphFunction();
}
}
//code for line graph
protected void LineGraphFunction()

[code]....

HTML:

<cc1:LineChart ID="LineChart1" Width="500px" runat="server" ChartHeight="300" ChartWidth = "450" TooltipBorderColor="#D8D8D8" TooltipFontColor="blue"
ChartType="Basic" ChartTitleColor="#0E426C" Visible = "false" BorderColor="Blue" BorderWidth="1px"
CategoryAxisLineColor="#D08AD9" ValueAxisLineColor="#D08AD9" BaseLineColor="#A156AB">
</cc1:LineChart>

Problem is:

In the "LineChart", everytime last "y-axis" point is going out of graph (i.e., somewhere in the footer of x-axis)

X-axis Y-axis

3.4 5.2

5.3 7

2 8.7

1) like in above table, all the point will plot except the last x-axis and y-axis points. Also, y-axis value = 8.7 goes away from graph and comes in the footer of x-axis line.

2) like if x-axis = 3, y-axis=6, then 6 goes out of the graph and comes in footer of x-axis line.

But this problem occurs only when Im using SELECT query for a "particular Id" i.e.,

SELECT x,y from Table1 where Id='Gaug9' and DeletionDate is null

If I will remove where Id=' ' then it will work fine. But I need to plot graph based on particular Id's.

C# - MS Chart Control Scale - Line Graph Show 12 Months?

Jun 7, 2010

On my X Axis, I have months. The chart shows up to 11 points, i.e. Jan - Nov of the same year, but when I add 12 points (Jan - Dec), it will do an auto label thing and change the interval for every 4 months.

How can I change the graph so that it shows 12 months before it does the auto labels?

Here is the server control code I am currently using.

Forms Data Controls :: Chart Points Not Signed?

Mar 24, 2010

In the control Chart, I add few points, selected from the database:

var Diagram_1 = Razrez_D1.Series ["D1"];
sqlDA.SelectCommand.CommandType = CommandType.StoredProcedure;
sqlDA.SelectCommand.CommandText = "Razrez_D1";
sqlDA.SelectCommand.Parameters ["@ date1"]. Value = Session ["date1"]. ToString ();
sqlDA.SelectCommand.Parameters ["@ date2"]. Value = Session ["date2"]. ToString ();
sqlDA.Fill (dataSet1, "Razrez_D1");
sqlDA.SelectCommand.CommandType = CommandType.Text;
for (int i = 0; i <dataSet1.Razrez_D1.Rows.Count; i + +)
(
string name_s = dataSet1.Razrez_D1 [i]. Name.ToString ();
name_s = name_s.Substring (name_s.IndexOf ('№')). Trim ();
Diagram_1.Points.AddXY (name_s, dataSet1.Razrez_D1 [i]. Count);
Diagram_1.Points [i]. BorderColor = System.Drawing.Color.Black;;
Diagram_1.Points [i]. BorderWidth = 1;
if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Red;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count)> = 4 & & Convert.ToInt32
(dataSet1.Razrez_D1 [i]. count) <= 5)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Yellow;
)
else if (Convert.ToInt32 (dataSet1.Razrez_D1 [i]. count) <4)
(
Diagram_1.Points [i]. Color = System.Drawing.Color.Green;
)
)

The problem is that the points on the X axis are signed that way: first is not signed, second is signed, third is not signed etc How can I sigh all points?

Draw A Line Between Two Dynamic Points On A Webpage Using HTML?

Feb 10, 2011

I'm working within the confines of ASP.NET and HTML.

I have a gridview on the left and a gridview on the right.

When the user selects a checkbox in the left gridview and a checkbox in the right gridview, I would like a line to be rendered that connects the checkboxes.

Is there an efficient way to do this? Anything approaching this?

DrawLine(LeftCheckBox.Location, RightCheckbox.Location, Red, 1px)

The only thing I can think of that would be work, but be a poor solution, is positioning and stretching an Image vertically based upon where the selected checkboxes are.
