give a code snippet which will explain how to use Binary streaming render type in ASP.Net Charting controls using $.ajax call in ASP.Net MVC Framework. ?
Ajax call will look like this-->
$.ajax({
type: "POST",
url: "/DrawChart/" + drawingParamter1+ "/" + drawingParamter2,
dataType: someSuitableDataType,
error: function(error) {
},
success: function(html) {
}
});
Trying to print an ASP.NET Charting control behind the scenes in my web app. I think it is a permissions issue with the printer as everything is ok up until the point where my code calls:
chart.Printing.Print(false);
bool finished = false;
while (!finished)
{
finished = File.Exists(settings.GetValue("statusfile")); // file which indicates document was printed
System.Threading.Thread.Sleep(1000);
}
At this point the page just freezes (or continues to load endlessly - infinite loop!) Understandably this is happening because I am 100% relying on the document being printed. I do intend to add a timeout, however, at the moment I am just trying to figure out why exactly the document is never being set to the printer!
I have given the account (which the AppPool is running under) permissions to all the relevant folders and even the pdf printer itself...Still nothing.
Am I missing something? Is there any issues with printing on the server side via ASP.NET? I have encountered some issues doing this via WindowsServices in the past not sure if it is a similar problem with ASP.NET websites.
Update
I updated the AppPool to give myself (admin) permissions and it is the same issue. So by the looks of things the job is never being sent to the printer. I can't seem to figure out why though...
Probably should have mentioned this in my original post....but I am invoking the printer through a referenced DLL, this code is not being called directly from my application (incase it matters). Also this runs fine on my Development machine which is running Windows 7 IIS7.0 where as the server is running Windows 2003 server with IIS6.0.
Update 2
I removed the while loop and just left in the chart.Printing.Print(false) line and turns out the document IS being sent to the printer. So the issue must be with the settings file not getting written which is why the loop never breaks out!
As you see above , we have more data in pie chart to plot and hence 3 DOTS appear at right bottom. Hence user cant see all the legends.Is it possible to have.say a tooltip on 3 DOTS so that when an user hovers,he sees entire / remaining legend list?
View 5 RepliesI am plotting a chart using charting control. The x-values are text values and y values are date values.
If there is same text multiple times, then the plotted chart has multiple bars of same value. I want the values for the same text to be on the same bar.
I am having a simple Azure cloud app(WebRole=ASP.Net MVC) which draws charts using ASP.Net Charting control. Chart RenderType = ImageMap Chart ImageLocation = "/Images/Chart_#SEQ(1000,1)" Number of app instances deployed on Windows Azure = 5 App contains a button which draws charts as per users parameters. When user clicks on this button, MVC action is called which provides necessary ViewData for drawing chart and returns a partial view which after getting rendered sends ImageMap and Image location to client.
When I try to draw charts from IE8 I always get the charts as per my parameters but when I simulataneously try to draw charts on FireFox sometimes I get wrong charts(wrong images). Is is due to roundrobin used - #SEQ(1000,1) or due to mutiple instances of my cloud app?
I am using MS Chart control (3.5), and have a requirement where I need to display 2 pie charts. The datapoints for the pie charts is set programatically. My doubts are as follows:
1. Can I display both the pie charts in a single chart control and area, or do I have to use two controls? (Currently I am using two controls)
2. How can I maintain the same size for both the pie charts? This is my main concern, since the pie sizes keep changing, depending on the number of datapoints. I tried using custom properties like "MinimumRelativePieSize", but it's not working.
I have the following jQuery event that gets fired every time an anchor is clicked. How can I pass a asp.net control (lets say a panel called "pnl_info") as one of the parameters, in addition to the "target" parameter i'm already passing?
<script type="text/javascript">
$(document).ready(function() {
$("a").click(function(event) {
$.ajax({
type: "POST",
url: "Default.aspx/Click",
data: "{target:'" + event.target + "'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function(xhr, ajaxOptions, thrownError) {
alert(xhr.responseText);
$("#myContent").html(xhr.statusText);
//alert(xhr.responseText);
},
success: function(msg) {
alert(msg.d);
}
});
return false;
})
})

I have a ReorderList from the Ajax Control Toolkit on an aspx page. What I want to do is to enable a button after the order of the items have been changed. I already have the javascript function in my page in a script block, but how can I tell the ReorderList to call the javascript after order has been changed?
View 1 RepliesFor an Umbraco project, I am trying to make a simple Ajax call.. I can't use PageMethods because I need to make the call from inside a UserControl.. I tried to do it via web service call like this:
Web service method:
[System.Web.Script.Services.ScriptService]
public class MapService : System.Web.Services.WebService
{
[WebMethod]
[Code]...
The problem is, "MapService.GetCities" method doesn't get invoked..
What might be the problem here?
Alternatively, what is there any better way to make these kind of Ajax calls in a User Control?
I have one user control which has 2 gridview first grid has columns (GroupName, Description, chkRemove checkbox) another gridview has columns (GroupName, Description, chkAdd), apart from that i dont have any code on .cs file of usercontrol.
I want to call same user control on 4 aspx pages and datagrid binding, sorting, paging and search functionality i want to do on respective aspx.cs pages not on user control where i am calling this uercontrol because for every aspx page field name is same but when i am binding the data to the grid that logic is different.
For first aspx page i called my usercontrol like this and everything is working fine: -

I have a page that contains a custom tab control. When you click different tabs, it does a an ajax callback. During that ajax call, the code dynamically loads a different control based on which tab was clicked, then adds it to the appropriate tab. So basically I have some code that does a switch statement, uses LoadControl(), then adds the control in.
The issue I'm having is that none of the javascript within each of those controls that gets loaded is getting registered on the page. Based on this thread:
[URL]
I thought I just had to switch from using Page.ClientScript.RegisterClientScriptBlock to ScriptManager.RegisterClientScriptBlock. I did that, but still nothing. Am I misunderstanding something about the ScriptManager? I want the javascript to be registered from within the dynamically loaded control, which happens to be loaded during an AJAX call.
I want to call MsCaptcha Control in Static WebMethod,for validating. so,I want to check mscaptcha value in javascript or jquery without refresh the page.I think it is my solution that i use JqueryAjax.

I found this Article from link : [URL] .... that explains how to call server-side Method from javascript,
I used your code, my server-side function is static, public, and also I added
[System.Web.Services.WebMethod]
and
<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePageMethods="true">
I've exempted the irrelevant bits of code. Essentially, I am trying to change the URL of an image control inside of an update panel inside of a custom user control from a function called inside an update panel from my main page. Using UpdatePanel.Update() isn't working: I end up waiting for the next full page POST to occur before all the updates I make to CustomControl from buttons within the main page's update panel are visible. I verified that Update() was being called via the debugger: there are no issues in that department.
Here, you can see Custom Control and the Button declared. The button is in an update panel to avoid giving a full POST and causing the whole page to reload.
<cust:CustomControl runat="server" ID="CustomControl1">
<asp:UpdatePanel runat="server" ID="UpdatePanel1"> <ContentTemplate>
<asp:Button id="Button1" runat="server" OnClick="DoStuff" />
</ContentTemplate> </asp:UpdatePanel>
This control stores images within their own seperate update panels because rerendering the images is very slow (it requires processing arrays of millions of datapoints) and the user only ever needs to modify one image at a time. I'm using Image1 as an example.

I am getting a strange error over one site vs another. I have created a chart web site that works, but now I'm moving that code into an existing website.

I have 3 columns of data that get returned from a stored procedure. Date, Error code,and Quantity. On one day we can have 8 different error codes, with different quantities.For example on the date of 18 Nov we had error code 101 = 24, error code 102 = 36, error code 103 = 4, etc. I am trying to display the different error codes in columnswith their quantity by date. There will be multiple columns for a given day because the error codes range from 101 -124. How can I display this? I currently have Just oneat a time being display based on which the end user picks.
If DS.Tables.Count > 0 AndAlso DS.Tables(0).Rows.Count > 0 Then
ErrorCodes.DataSource = DS
ErrorCodes.Series("Exceptions").XValueMember = "Error Date"
ErrorCodes.Series("Exceptions").IsValueShownAsLabel = True
ErrorCodes.Series("Exceptions").YValueMembers = "Total"

I'm currently developing a website that shows multiple charts that I build using data from SQL tables. I've used and followed Scott Mitchell's tutorial [URL] and K. Scott Allen's ChartBuilder class [URL] and all works well.
However when have two series that I want to show on the same Chart, if one set of data does not have all of the X values the other series does, the chart blindly puts all the data on, ignoring trying to match the X values of the other series, therefore mismatching the X values when the chart is shown.
I know that I can fiddle the data so that both sets of data have the same X values, however I'm trying to make the class handle anomalies in the data so that I don't have to worry too much about the data.
Which storage method should I use when using ASP.NET Charting Tools? I'm currently using memory, because it seems like the most straight-forward and easy to implement option. Is there any reasons I should be aware of why I should choose one of the other options? The charts generated will be useful only for an overview kind of purpose (checking to see if a data collection is following a certain pattern, as it is being built day by day), and this function won't be used frequently.

Any body worked with MS Charting control for VS 2008.
I am using the chart control to displaying marks secured by students in different exams.
Series of the chart can be dynamically generated.
I am looking for a charting tool to generate charts in my ASP.Net page which will allow me to customize the charts to a great extent like changing the background of chart, specfying custom x and y axis and much more.Moreover, another major requirement is that the chart should be interactive enough. I would like to select data points on my chart, select a range of data points on charts by making a selction with mouse clicks and use these selections for further processing.
