View 3 RepliesAt work we currently have a custom in-house built winforms app for the business users to view reports. It has role-based security and several administrator functions.My boss is thinking about getting me to port this app to webforms.My question is, are there options other than custom built winforms and webforms apps for deploying/viewing/administrating Crystal Reports at an enterprise level (role-based security, easy report deployment, etc)? I'm thinking about third-party packages or perhaps applications provided by Microsoft/Business Objects/SAP?

I try to convert winform component to webform component
(Winform Component (PictureBox) to Web User Control (asp:Image)), but it fails.
I've developed a very simple ASP.NET (jQuery) application. The RDBMS is MS Sql Server but I could easily convert it in MS Access. My client would like to have it available on a CD, ready to run. I was thinking to convert it in a WinForm app but, still, I have to install the framework on the client. Is there any other "possible" solution?
View 5 RepliesSituation: I have a web application which shows errors and where you can accept those error messages. I also have a service, which checks errors from a system and sets the error messages in the database. When I accept an error in the web application, i would like the service to know which error message has been accepted, so that it can do some other actions. My guess is that this could be done through some sort of trigger, but i can't figure out how.

eg I'd like to only display on the screen the Surname, but on dump to csv would like firstname too.
I've tried visible = false, and display = false on the GridBoundColumns, but then they don't come out on the csv.
<telerik:RadGrid ID="grdAuctions" runat="server" AllowAutomaticDeletes="True" AllowAutomaticUpdates="True"
AllowPaging="False" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="odsAuctionSales"

<ExportSettings HideStructureColumns="true" />

I'm getting some Xml back from a service. I would like it to be the datasource of a grid view on my aspx page. Here is a sample of the Xml
<?xml version="1.0" encoding="utf-16" ?>
<ArrayOfTripTollCompleteDC xmlns:xsi=[URL]"
xmlns:xsd=[URL]>
<TripTollCompleteDC>
<TripTollId>5</TripTollId>
<DMSLaneModeID xsi:nil="true" />
<HOVOnly>false</HOVOnly>
<CreateDateTime>2010-06-07T15:54:01.023</CreateDateTime>
<ConfigVTMSDelaySeconds>5</ConfigVTMSDelaySeconds>
</TripTollCompleteDC>
and here is my code that parses the xml and tries to bind the grid. What am I missing here?
var retVal = service.GetTripDetailsByTripID(tripId);
var xmlTrips = XDocument.Parse(retVal);
var tripTolls =
from t in xmlTrips.Elements("TripTollCompleteDC")
select new {
TripTollId = (int)t.Element("TripTollId")
, DMSLaneModeID = (int?)t.Element("DMSLaneModeID")
, HOVOnly = (bool)t.Element("HOVOnly")
, CreateDateTime = (DateTime)t.Element("CreateDateTime")
, ConfigVTMSDelaySeconds = (int)t.Element("ConfigVTMSDelaySeconds")
};
grdTripDetails.DataSource = tripTolls;
grdTripDetails.DataBind();
I realize these are anonymous types. Is that a problem? I have verified the service is returning the Xml as stated above. Can anyone out there point me in the right direction? Just for completeness, here is the grid markup <asp:GridView runat="server" ID="grdTripDetails" />
I have an entity "Order", which contains a set of states. Every state has date and name.
I want show grid with all orders and in grid one column with last state of order. But I dont understand how to do it.
I have a look-up grid with two columns, Last name and AddressI need that look-up grid to take as little screen real estate as possible, but I have to include the "Select" function next to every row.Any way I could fire the Select function by clicking on the ROW verses the "Select" function
View 8 RepliesI am trying to create a recipe system that will pull material amounts from an already built inventory database upon request for testing purposes of the different recipe runs. What is throwing me for a loop is that each time a user will request a recipe comparison they will have a different number of recipe trial runs for comparison purposes. In order to do this I'm guessing you will need to generate a gridview-like control with a dynamic number of columns which would be specified on a web form page prior to arriving at the recipe formulation page which will contain the control for the recipe formulation. As a result the user will have different columns and rows on this formulation page, with the rows being a static number of 30 (30 being maximum amount of ingredients to include in each recipe). The columns will contain the recipes to be compared, i.e. ProductRun1, ProductRun2, ProductRun3, where the number of ProductRunX will be determined by user input. So the user when they come to this aspx page will be presented with a blank editable grid of X columns by 30 rows deep. The left-most column will contain the ingredient names in a drop down box for users to select to input into their recipe and the rest of the columns will be editable fields where the user can type in the amount of each material to be used. The setup will look roughly like this:
| ProductRun1 | ProductRun2 | ProductRun3 |
ProductRun4 | ... |
-------------------------------------------------------------------------------------------------------
Material1 | Material1_Amt | Material1_Amt | Material1_Amt | Material1_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material2 | Material2_Amt | Material2_Amt | Material2_Amt | Material2_Amt | ...|
-------------------------------------------------------------------------------------------------------
Material3 | Material3_Amt | Material3_Amt | Material3_Amt | Material3_Amt | ...|
-------------------------------------------------------------------------------------------------------
(...)
-------------------------------------------------------------------------------------------------------
Material30 | Material30_Amt | Material30_Amt | Material30_Amt | Material30_Amt | ...|
-------------------------------------------------------------------------------------------------------
So my question is how would I go about tackling something like this and what controls would I use. All of the forum posts around the internet show the GridView control being tied to data in a database already and not having the ability to have a fully blank and editable table upon the page loading so that it can accept user input. Another wrench into the situation is that the column numbers can vary. What control would be used in this situation or would it be better to use just a repeater of textboxes to build this type of control? Another thing is once the control is built how can you pull the data from such a control with the intentions of entering it inside a sql server database?
If I use a regular distinct selector with MySQL and show the results in a repeater I can show the the data in the webform with the following code.
<%# DataBinder.Eval(Container.DataItem, "posted") %>
But If I use this code:
"SELECT DISTINCT mid(posted,6,1) ORDER BY posted DESC"
I get the following error trying to use the code above.
DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name 'posted'.
So how do I get the data I've collected with the "DISTINCT mid"-selector to appear in the webform?
I am trying to do a workaround for an application that can only display webforms. So I want a default webform page with an iFrame in it. I would like the iFrame to display an MVC page. Is this possible?
