Forms Data Controls :: Creating New Instance Of Chart Displayed In Table

May 5, 2010

I am building a .net page and need to display some data residing in a database. Some of it's working, some not. I would like to use a table to display the data with the format below..

Table
row - question data
row - answer (count)
row - next answer (count)
row - BarChart representing the answer counts for question
row - next question data
row - answer (count)
row - next answer (count)
row - BarChart representing the answer counts for question

The question data and answer count rows are generated with no issue. However, the rows containing the barchart are problematic. Not sure how to create a new instance of a chart on the fly and hook in all the methods, etc. and get the control added to and displayed in the tablecell. Been looking for examples to create the chart on the fly with no real results.

Forms Data Controls :: Programmatically Creating Chart Control And Adding It To Dynamically Generated Table?

May 21, 2010

I am stuck in chart controls...Here is my prob... There is a ListBox containing some items...when user selects multiple items from the list box I want to generate a dynamic table with the number of columns same as that of the number items selected in the listbox. And for each selected item I want to show a seperate chart in the columns...Currently I want the same chart control for every selected item (i.e. a static hard coded chart that i will replace later by dynamic values)....I am using a method that draws a chart control using a sample dataset... I am calling it each time when a new column is created..Also the DrawChart method executes for the first column only and throws an index out of range exception! after the first execution...my code is not working...here

my code...

VS 2008 Chart Series - Fill From Data Table

Jul 13, 2012

I am using Chart control to loop through and fill from GridView and it works fine.

Code:
myProductSeries.Points.AddXY(GridView1.HeaderRow.Cells(i).Text.ToString, GridView1.Rows(0).Cells(i).Text.ToString)

My question: How would I do that using a DataTable instead, is that possible. Does DataTable have a "Header" like GridView so do I fill the X value?

Forms Data Controls :: .net 4 Chart Control - Hide Labels In Pie Chart?

Apr 28, 2010

Am I going mad/blind? Probably a combination of the two.

How does one go about removing the data labels from a pie chart with the new chart control in .net 4?

I can get these to display as tooltips absolutely fine, but ultiamtely I'd like the labels not to be present as it looks rather busy.

I've searched previous answers and seen code behind resolutions but surely there must be some sort of code infront option to turn these labels off?

Forms Data Controls :: Pie Chart Size In Charting / Using MS Chart Control (3.5)?

Aug 12, 2010

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.

But I can't get this into a stacked chart.

Forms Data Controls :: Chart Control Tooltip On Pie Chart Not Updating On Partial Postback?

May 21, 2010

I started using the awesome chart controls with my asp.net apps recently and so far they've been nothing short of breath taking. Right now I have a weird problem, on the first load of my page, the chart control appears correctly and the tooltip is correct, however, when I update it with new data, the chart displays correctly, but the tooltips are for the previous set of data.

I hope this makes sense. The first time I load the chart, the pie chart segments and tooltips are correct, after a partial postback (to get the new data), the pie chart segments are correct but the tooltips are for the previous data set.

Basically once the tooltips are set the first time, they can't be updated after that without a full page postback.

Here's how I set the tooltip:

[Code]....

Anyone else noticed this behaviour and have a work around?

Currently my only workaround is to check for a partial postback and not render the tooltip, which I'd rather not do as the tooltip display actual statistical data as opposed to the pie itself (which uses percentages).

Forms Data Controls :: How To Produce A Blank Record In A Dropdownbox Control

Mar 30, 2011

I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.

I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.

SQL Server :: Produce DDl Box From DB Query

I am trying to produce a DDL box with the following listing from a DB query.

13245
12345-

12348
12348-R

Some 5 digit codes do not include a suffix in the record, the following query will only show the 5 digit codes with a suffix.

SELECT itemCode + '-' + itemSuffix AS code, keyID, itemCode, itemSuffix
FROM item
ORDER BY itemCode

How can I get the codes without a suffix to appear with the codes that have a suffix? The itemSuffix field in the DB is NULL for no data records.

Inheriting From DataSourceControl Doesn't Produce IDataSource

Feb 15, 2010

I am trying to create a custom datasource control. I have been following this article to the letter (I think...). I have a skeleton / basic implementation of my datasource, however when I declare it in the markup and try to statically bind it to a gridview, I receive the following error:

The DataSourceID of 'grdVw' must be the ID of a control of type IDataSource

This seems extremely strange to me, since my datasource inherits from DataSourceControl, which in turn implements IDataSource. Even if I explicitly implement IDataSource in my custom datasource, it makes no difference. My Markup is:

<DataBrokerDataSource ID="objSrcDBroker" runat="server" />
<div>
<asp:GridView ID="grdVw" DataSourceID="objSrcDBroker" DataMember="Table0" runat="server">
</asp:GridView>
</div>
<div>
<asp:GridView id="grdVw2" DataSourceID="objSrcDBroker" DataMember="Table1" runat="server">
</asp:GridView>
</div>

And my control is:

Public Class DataBrokerDataSource
Inherits DataSourceControl
Implements IDataSource 'Have tried with this statement included AND excluded = same result
Protected Overrides Function GetView(ByVal viewName As String) As System.Web.UI.DataSourceView Implements IDataSource.GetView
'Code here
End Function
Protected Overrides Function GetViewNames() As System.Collections.ICollection Implements IDataSource.GetViewNames
'Code here
End Function
End Class

Looking at the stack trace shows that the error originates at:
System.Web.UI.WebControls.DataBoundControl.GetDataSource().

I have examined this method in reflector (see below), looking at this (based on the error message that I am getting) it appears to me as though the FindControl part is succeeding but that the source = control as IDataSource; leaves source as a null value, i.e. the conversion fails - But Why?

protected virtual IDataSource GetDataSource()
{
if ((!base.DesignMode && this._currentDataSourceValid) && (this._currentDataSource != null))
{
return this._currentDataSource;
}
IDataSource source = null;
string dataSourceID = this.DataSourceID;
if (dataSourceID.Length != 0)
{
Control control = DataBoundControlHelper.FindControl(this, dataSourceID);
if (control == null)
{
throw new HttpException(SR.GetString("DataControl_DataSourceDoesntExist", new object[] { this.ID, dataSourceID }));
}
source = control as IDataSource;
if (source == null)
{
throw new HttpException(SR.GetString("DataControl_DataSourceIDMustBeDataControl", new object[] { this.ID, dataSourceID }));
}
}
return source;
}

Make Custom Validators Produce Alert

Mar 3, 2010

All ASP.Net client validation messages can be shown as an alert by setting the ShowMessageBox="True" property on the ValidationSummary control. This works fine for anything that happens on the client.

For the custom validators that validate server-side I had assumed that what would happen is that when the page is returned to the browser, ASP.Net would inject some javascript to show the alert box. However this isnt the case.

If you had relied on the message box to show detail and just have a * next to the erroneous field (as per my clients req's) then it wont work as intended. Does anyone have a solution for doing this? What I want is a way to possibly override the ValidationSummary control to inject javascript onto the page or something like this.
