How to dynamically generate a report with a parametrized SQL query as a data source

December 31, 2000, 4:00 pm

0

Description:
 I need to implement a generic kind of web report viewer to display the result of my SQL query, which accepts some parameters.

Solution:
 This can be done by creating an XRTable control dynamically.

To pass a table name (which is a query parameter), you can use a query string variable. As a result, you can pass the "TableName" parameter as follows:
http://hostname/PassSQLQuery/ReportViewer.aspx?TableName=Customers.

Then, the XtraReport code-behind methods will populate data using the SQL query, which returns all the table rows from the table.
In the final step, an XRTable control is created, and gets bound to the column names of the data table.

Hi ,

i want to deign the report and bind only the values at run time , because it is difficult to align the controls during run time.

is there a way to place the controls during design time and just bind the values at run time in asp.net web application.

How to style GridControl's summary items separately when summary items are aligned by columns

December 10, 2013, 12:26 am
$
0
0

Starting with v16.1, TableView provides the following properties, which allow you to style each GridControl's summary item separately:
1. FixedTotalSummaryElementStyle

2. TotalSummaryElementStyle

3. GroupColumnFooterElementStyle

4. GroupColumnSummaryElementStyle



For versions 15.2 and older, when group summary items are aligned by columns, it is necessary to use the TableView's GroupColumnSummaryItemTemplate property to style GridControl group summary items.
The main idea of this approach is to define a custom ItemsControl inside the GroupColumnSummaryItemTemplate, bind its ItemsSource property to the collection of group summaries and show summary items as child ItemsControl elements. To customize summaries you can use ItemsControl properties, for instance, ItemTemplateSelector.

Dear Support Team,

I've integrated this solution into my project.
It is working well but I have little (huge) problem with it.
If I use Enter key to move cursor from the column to the next column, which is a cascased combobox, and I'm fast and I use 2 times Enter key the combobox value is shown and cleared and the focused column is the next column after combobox.

I've analyzed the code.
The OnBatchEditStartEditing set value of Combobox but the PerformCallback of combobox clears it.
In client side event endcallback I reset it back to the original value. It is working well if I do not leave the combobox column fast.

I hope you have solution for this problem.

Best Regards,

Zoltán

This example demonstrates how to use a custom editor for editing in the PropertyGridControl.

This task can be completed in the following ways.
1. Use a custom UITypeEditor. For this, create a custom UITypeEditor descendant and mark a property of a corresponding object with the System.ComponentModel.Editor attribute in the following manner:

[C#]
publicclassFile{[System.ComponentModel.Editor(typeof(UIEditors.FilteredFileNameEditor),typeof(System.Drawing.Design.UITypeEditor))]publicstringPath{get;set;}

 Please refer to the UITypeEditor Class article for more information.

2. Assign a ButtonEdit to a cell as shown in the Assigning Editors to Editor Rows  article and handle its ButtonClick event.

How to customize the default Find Panel filtering algorithm

December 30, 2010, 12:42 am
$

Find Panel uses an extended syntax that allows you to specify complex criteria. You can find detailed information here:
- Find Panel

However, sometimes it is necessary to exclude/include some rows in the resulting list according to your custom logic. In this case, you can filter rows manually by handling View.CustomRowFilter Event. This example demonstrates how to construct your own filter criteria and use ExpressionEvaluator to check whether a row should be hidden.

For demo purposes, this example just shows how to find exact matches of a typed string. The same result can be accomplished with the default behavior if you enclose your text in double quotes in Find Panel. To provide your own logic, just modify the MyConvertFindPanelTextToCriteriaOperator method as your needs dictate.

Question Comments
Added By: Sigol at: 9/6/2012 2:34:45 PM    

In the text above "if you enclose your text in commas in Find Panel" I think should read "if you enclose your text in DOUBLE QUOTES in Find Panel".

Added By: Arnaud Chevallier at: 12/21/2012 5:35:48 AM    

This may be usefull, as for example replacing parenthesis by double quotes. However with this method the results are not highligted anymore. Is there any workaround ?

Added By: Catalin Zainescu at: 12/21/2015 4:07:00 PM    

The suggested workaround feels more like black magic... For example, can you guarantee that "ColumnView.GetFindToColumnsCollection" method will always be there?

Do you have any plans to add an option to change this default filtering behavior? At the very least, it would be really nice to be able to switch from "OR" to "AND" filtering logic instead of having to add "+" to every token.

Added By: Nikita (DevExpress Support) at: 12/22/2015 6:41:18 AM    

Hello Catalin,

I understand that this example a quite complex. And while we really cannot guarantee that we won't change the GetFindToColumnsCollection method, we do guarantee that we will keep this example in the working state. So, if we change some grid code, which will break this example, we will upload a new version of this example to the site. 
I also understand that such functionality is useful, so we are going to consider introducing similar functionality in the future.

How to use OData (WCF Data Services) to provide data for a report

July 7, 2015, 9:27 am
$
0
0
At the moment, XtraReports cannot connect to an OData data source directly. 

Our reporting tools, however, are data source agnostic and support data sources of different types including .NET data providers, lists (implementing the System.Collections.IList, System.ComponentModel.ITypedList, or System.ComponentModel.IBindingList interface), and XML data sources. To learn more, refer to Data Binding Approaches.

So, to provide report data through the OData service, get IList data from the OData Service and then pass it to a report. Here are implementation details.

1. Add the OData Service Reference to your project. Now, the OData service context is registered in the application. See the Calling an OData Service From a .NET Client (C#) article for details.
2. Create a data model from the OData Service context. This data model will retrieve data from the OData service and return IList data.

Please note that OData defines query options that can be used to filter, sort, page data, and so forth. For more details, see the LINQ Considerations (WCF Data Services) topic on MSDN.

3. Bind a report to this data model through the ObjectDataSource component. Please note that it is necessary to retrieve actual data from a custom object data source. Please refer to Retrieve the Actual Data.

How to implement custom WinPropertyEditor based on the ListBoxControl

September 19, 2013, 12:11 am
$
0
0

Scenario

This example illustrates how to implement a custom WinPropertyEditor with ListBoxControl to edit reference properties in DetailView:


Steps to implement

1. Add a new class inherited from the WinPropertyEditor as shown in the Module.Win\Editors\CustomListBoxEditor.xx file.

This editor is inherited from WinPropertyEditor not to configure data bindings manually.
2. In the Model Editor, set the PropertyEditorType attribute to the custom editor type for a required reference property node, as shown in the example's Model.XAFML file.

Important notes
1. ListBoxControl cannot correctly work with the ImmediatePostData property, because it does not contain the SelectedItemChanged event. Without this event, ListBoxControl does not send a notification to the binding mechanism when item selection is changed. This behavior was inherited from the default ListBox control. To avoid this behavior, subscribe to the ListBoxControl.SelectedIndexChanged and send notifications to the binding manually as shown in the Module.Win\Editors\CustomListBoxEditor.xx file .

2. This editor is designed to work only in DetailView.

Question Comments
Added By: FSuster at: 11/20/2013 1:36:34 AM    

Thanks for this usefull example. Maybe I found a bug.

This is the scenario: TestItem has a n:1 association to CategoryItem
Several CategoryItems are already saved as well as an object of the type TestItem. For this TestItem a specific CategoryItem was selected. In the TestItem's detail view the CategoryItems are displayed as a CustomListBoxEditor.

1. Open the existing detail view of the TestItem. The right value in the CustomListBoxEditor is selected.
2. Close the detail view.
3. Reopen the detail view. Now the first item of the CustomListBoxEditor is always selected, no matter what CategoryItem was saved in the TestItem.
==> The binding of "SelectedItem" only works once.

Stefan

Thank you for sharing your implementation with us. We greatly appreciate this.Added By: Don Boitnott at: 8/17/2016 5:16:54 AM    You need to change the call to GetResourceByFileName() to include the ImageType:

using (Stream str = ImageResourceCache.Default.GetResourceByFileName(imageInfo.Name, imageInfo.ImageType))
 
...otherwise, you get an incomplete (and seemingly random) set of images.
