Infragistics Aikido WebDataGrid offers a nice built-in ColumnMoving behavior. When enabled – it allows user to drag columns to change their order:
But what if you want to keep this behavior and add your own custom column drag-and-drop? For example to create your own column grouping, since WebHierarchicalDataGrid doesn’t handle grouping well.
In this post I will describe a simple technique how to both keep behavior shown above and implement custom column drag-and-drop:
I had high hopes for Infragistics Web Hierarchical Data Grid control. Especially in NetAdvantage 10.3 release (current as of this post). Control from Aikido Framework, build on AJAX from ground up, lightweight and fast – I was really excited.
Unfortunately it didn’t turned out exactly as I expected.
First – WHDG cannot bind to a flat ADO.NET data table. Why, you ask, I need to bind flat data to an hierarchical control? Well, it’s the only grid in Aikido that supports OutlookGroupBy mode and I need to be able to group my flat data. But attempt to bind WHDG to DataTable throws an enigmatic InvalidOperationException without giving any clue as why. There’s a workaround – to create a dummy DataSet, add the table to it and bind control to the dataset – but that’s just silly. And that’s not the worst of it. Continue reading →
Infragistics UltraWebGrid offers extensive client-side Object model and objects at several level of hierarchy offer “.find” method to locate cell with specific data. For example to locate a cell with specific text in a specific column – following code can be used:
//Find cell in first grid column with text "67"
var oGrid = igtbl_getGridById('xmyGrid')
var iLookUpValue = '67'
var oFoundCell = oGrid.Bands[0].Columns[0].find(iLookUpValue, false)
This works, but unfortunately the “.find” method searches for cell’s text instead of value, thus finding any partial match. In the example above cells with values 567, 671 etc. will be found which is no good in many cases, for example when you’re looking for a numeric ID.
Fortunately the “.find” method accepts regular expression as a search parameter. The solution is to apply “^…$” RegEx expression to perform exact match. So if we change the last line in the code above to:
var oFoundCell = oGrid.Bands[0].Columns[0].find('^' + iLookUpValue + '$', false)
only exact match will be searched for.
Infragistics UltraWebGrid offers a nice grouping feature: when the grid is in OutlookGroupBy mode, you can group similar data with very little coding required, you can go from this view:
to this:
by just dragging columns to designated area.
But what if you want to group by first letter of a name or a year of a date? New WebHierarchicalDataGrid control offers this functionality after 10.2 release of Infragistics NetAdvantage, but if you invested years of work in classic UltraWebGrid – it’s not easy to move to a brand new control cold turkey. There’re other methods that offer custom grouping for UltraWebGrid, but the ones I found were pretty convoluted (like create a hidden column, populate it with data to group by etc.) Here is a simpler approach.

If you’re using Crystal Reports 2008 in your ASP.NET application, and after deploying to a 64bit server getting following error:
An error has occurred while attempting to load the Crystal Reports runtime. Either the Crystal Reports registry key permissions are insufficient, or the Crystal Reports runtime is not installed correctly. Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required. Please go to http://www.businessobjects.com/support for more information.
then switch your application to 32bit mode. In case of Windows 2003/IIS6 entire server will have to be switched, in case of Windows 2008/IIS7 a dedicated 32bit application pool can be established for your application.
A while back I posted a method to highlight rows on mouse over in Infragistics UltraWebGrid. Over the time turned out that it had several limitations the main being: if you enable additional styling for some elements of the grid, they’re not preserved after mouse-over/mouse-out events. For example if you set a SelectedRowStyleDefault property with a different background and then move mouse over a selected row – that style will be removed.
So, here’s a complete solution to work around that limitation: Continue reading →
If you’re using Infragistics UltraWebGrid and experienced an odd behavior where the grid does not display the right-most vertical border line – there’s a workaround.
By default 2 elements contribute to the grid border – border from RowStyleDefault property and border from FrameStyle property. For some reason IE6/7 (yes, some people still use those) do not render the right border of the last column, even though all 3 properties (BorderColor, BorderStyle and BorderWidth) are set. So the solution is to have FrameStyle lend that border:
As a result, the right border is displayed correctly in all versions of IE.
In one of my recent projects I needed to validate whether user’s input is a valid date, and this needed to be done client-side, in browser prior submission to the server. Lazy as I am, I Googled for a ready-to-use code snippet. There’re plenty of versions out there, but most of them offer incomplete solution and none of them take into account browser locale, you know – the language settings:
So I decided to cook something of my own Continue reading →
This is probably a very obscure situation, but it happened to me, it could happen to someone else. Scenario: an ASP.NET page with Infragistics UltraWebGrid inside of a WARP panel. A button outside the WARP serves as a trigger for partial postback. First click on the button causes expected partial postback, but on the second click page does full postback and is screwed after that. The issue happens only in IE6/7, page works correctly in IE8.
Another condition – page contains ASP.NET AJAX ScriptManager control with ServiceReference path pointing to an ASMX WebService.
Turned out the issue was caused by project being left in debug mode (in web.config debug=”true”). Which caused WebService page to be loaded with parameter “jsdebug” in query string. Which apparently IE6 and 7 didn’t like very much. Switching to debug=”false” in web.config solved the problem.
If you’re binding an ADO.NET DataTable to Infragistics UltraWebGrid and then programmaticaly sort the grid (e.g. add a column to a band’s SortedColumns collection) you may get an error:
Cannot find column My Column Name.
with stack trace starting from grid databinding and finishing in datatable’s sorting:
at System.Data.DataTable.ParseSortString(String sortString)
at System.Data.DataView.CheckSort(String sort)
at System.Data.DataView.set_Sort(String value)
at Infragistics.WebUI.UltraWebGrid.DBBinding.ProcessDataViewForFillRows(DataView dataView, RowsCollection rows)
at Infragistics.WebUI.UltraWebGrid.DBBinding.FillRows(UltraWebGrid grid, RowsCollection rows, IEnumerable datasource)
at Infragistics.WebUI.UltraWebGrid.DBBinding.BindList(IEnumerable datasource)
at Infragistics.WebUI.UltraWebGrid.DBBinding.DataBind(Object dataSource, String dataMember)
at Infragistics.WebUI.UltraWebGrid.UltraWebGrid.DataBind()
If the grid binds OK without sorting and grouping, but fails with either – most likely the culprit is one of the columns in data table. Continue reading →
