  1. I set up a grid with master-detail feature. It is similar to the real estate example "DataBind_MasterDetail.aspx".It works fine in a web page, but my application is based on user controls.When I use the exact same grid and ObjectDataSource code in a user control it does not work correctly.It displays data correctly in the master grid. But when the user clicks the "+" on a row you get the grid's "wait" message repeatedly. You never get a display of the detail data.I wonder how to fix it or even how to debug what is happening after the user clicks the "+". John ***** protected override voi
  2. I need to run the example Real Estate Application to learn how Grid FX works. I can get the main page but clicking any link causes an error. Can anyone suggest how to fix it? Below is the error page. Server Error in '/Real Estate' Application. -------- Failed to map the path '/'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.InvalidOperationException: Failed to map the path '/'. Source Error:
  3. PDyer, Now that I have a license for gauges, this technique actually works. Thank you. Steve
  4. AndreG Maybe some of my questions could be answered by the Real Estate example project. However I am unable to run any of the pages. Maybe you can suggest how to resolve this error that occurs for every page: Server Error in '/Real Estate' Application. Failed to map the path '/'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

  5. AndreG, Thank you. Still when I adapt this code I am not able to get numeric labels on y-axis. Two things could help. 1) Identify the specific place in the grid definition that causes numeric labels on y-axis, (or refer me to documentation about this issue) and 2) Provide the complete html for the page and the code-behind the page (or the complete project file). Since the demo project does show the y-axis correctly I would like to setup this exact project and then morph it into mine, e.g. start with something that works. I would need to see the ObjectDataSource(s) etc. and any co
  6. When the user selects and expands dispaly of a graph, I want to have numbers labelling the scale on the y-axis. But now there are no numbers. Online demo shows a scale on the y-axis but I could not find anthing in documentation. *** my example grid *** <GridFX:Grid ID="Grid2" runat="server" DataSourceID="GetQtyPickedPerSecondAvgAllUsersDataSource" Width="100%"> <Columns> <GridFX:FieldColumn Field="MPL_UserID" Title="User"> </GridFX:FieldColumn> <GridFX:FieldColumn Field="QtyPickedPerSecond" Title="QtyPickedPerSecond"> </GridFX:FieldColumn> &
  7. Stephen, I'm trying to use master/detail technnique with ObjectDatasource (where the code to get the data is defined in the program, not the grid designer). It works if my child datasource has no parameters. But I need to give the child a parameter value that depends on which grid row the user selected. The parameter should be the value of one of the datafields. If you can send an example it would be fine. Or you could look at my code to see if I am using the wrong approach. The Real Estate example that comes with Grid FX uses an AccessDataSource rather than ObjectDatasource. It does
  8. 1. In your example how does this code: radialGauge1.MainScale.Sections[0].Min = Convert.ToDouble(NewMin.text); radialGauge1.MainScale.Sections[0].Max = Convert.ToDouble(NewMax.text); fit with the "at the end" code? Precedes it, goes after it, or? For example it is not clear to me the relationship between radialGauge1.MainScale and radialGauge1.Scales 2. How does the "at the end" code get linked to a specific grid instance like Grid1? 3. Suppose I already defined in the html, using the designer, a DataField with associated gague and sections. Is it possible in the
  9. I use Visual Studio 2008. I am a new user of GridFX. This grid is not yet very useful to me because the same type problems reported earlier continue. Almost every time I use the designer to put a grid on a user control or a web form I get an error message: "Error Creating Control - Unable to cast object of type 'GridFX.WebForms.Grid' to type 'GridFX.WebForms.Grid' On the same page or user control I can put html code in the source view and then I see a grid with no errors in design view. However when I try to use the smart tag in the designer to modify grid properties, as soon
  10. Thank you for your suggestions. The behavior of this demo seems correct.
  11. Typically a user would want to specify ranges for gague colors rather than having these values fixed at design time, so we need to do it in the program. e.g theseMax and Min values that can be set in the designer: <ChartFXGauge:Section Bar-Color="255, 0, 0" Bar-Visible="False" Max="0.4" Min="-Infinity"></ChartFXGauge:Section> < ChartFXGauge:Section Bar-Color="255, 255, 0" Bar-Visible="False" Max="0.7" Min="0.4"></ChartFXGauge:Section>< ChartFXGauge:Section Bar-Color="124, 252, 0" Bar-Visible="False" Max="Infinity" Min="0.7"></ChartFXGauge:Section> How ca

    Format guage

    Especially because I still cannot configure the grid using visual studio designer, due to a control error, I need to do things in program code. For example I want to set up a column with a circular guage and another with a traffic light. The only program example I could find anywhere shows only how to do a linear guage: http://support.softwarefx.com/SupportDocTree.aspx?Prod=GridFX10&Type=P It looks like the NumberFormatter may be the solution but I see no guidance or examples on how to link it to a column with a guage.
  13. Reference the error: "Type must be one of the .NET numeric types" Stephen, I did not find any documentation about the DataField types. For example searching for "NumberField" found nothing. But I found the problem is I defined a field: GridFX:NumberField that apparently works only for integers. But the data vaules are real numbers not integers. So I need a field type that can handle real values. What is it?
  14. 1. I downloaded and installed a new grid version. When I put a grid on a web form or user control I get the error: Error Creating Control - Grid1Failed to create designer 'GridFX.WebForms.Grid, GridFX.WebForms, Version=1.0.2986.27353, Culture-neutral, PublicKeyToken=a1878e2052c08dce 2. I ran anyway with this grid definition: <GridFX:Grid ID="Grid1" runat="server" Width="550" DataSourceInCode="True" OnDataSourceSelecting="Grid1_DataSourceSelecting"> <DataFields> <GridFX:TextField DataPath="MPL_UserID" Title="User"> </GridFX:TextField> <GridFX:Number
