Hello jouin,

Please let me know if you need any further assistance with the matter.

Hello,

That is just what I needed!!!!  I only need an example on how to create a templatedatafield and add and image button.

Thanks!

Nikolay,

I too am trying to construct WebDataGrids in code behind throughout a large system that we are still trying to upgrade from old UltraWebGrids.  We are attempting to use both ViewState and DataViewState to persist data between postbacks.  I am struggling with determining the appropriate events in the page lifecycle during which construct the columns, behaviors and editorproviders.  I have seen many odd behaviors in a multitude of attempts that including dropdownproviders that lose knowledge of their list items during AJAX postbacks (while the overall grid still retains data), currencyeditorproviders that remember the column to which they belong, but forget their MaxValue parameter, DropDownProviders that forget not to EnableRenderingAnchors, and many more I will not detail here. 

I am looking for a best practices guide or complete published example of how to constuct a WebDataGrid in code behind (any .NET language will suffice).  Preferably the example would include texteditor providers, numeric and/or currency editor providers, data providers, and most importantly DropDownProviders that have a dynamically loaded list of values (as in a real world scenario in which values come from DB) rather than hardcoded items in markup. 

Does such an example or guide exist for public distribution?

Thanks,

Hello jouin,

If you have any further questions, please feel free to contact me.

Hi jouin,

I would suggest you to create the grid behaviors on page load.

Let me know if this helps.

Hello,

I am getting index was outside the bounds of the array when I click on button:

ASPX

<ig:WebDataGrid ID="WebDataGrid1" runat="server" DataSourceID

="SqlDataSource1">

</ig:WebDataGrid>

Codebehind:

Private Class CustomItemTemplate

Implements ITemplate

"ITemplate Members"

Public Sub InstantiateIn(ByVal container As Control) Implements ITemplate.InstantiateIn

Dim edit As New ImageButton()

edit.ID =

"EditButton"

"Edit"

"edit"

"icons/pen_24.png"

DirectCast(DirectCast(container, TemplateContainer).DataItem, DataRowView)("Id").ToString()

edit.ToolTip =

"edit"

End Sub

Region

End Class

Protected Sub Page_Init(sender As Object, e As System.EventArgs) Handles Me.Init

'Load Data

"select * from InterestTypes order by Name"

'Build Base Grid

"400"

New Unit("100%")

WebDataGrid1.AutoGenerateColumns =

False

"ID"

'Build Columns

Dim DFid As New BoundDataField(True)

DFid.Key =

"ID"

"ID"

"ID"

True

Me.WebDataGrid1.Columns.Add(DFid)

Dim DFPName As New BoundDataField(True)

DFPName.Key =

"Name"

"Interest Type"

"Name"

Me.WebDataGrid1.Columns.Add(DFPName)

Dim DFActive As New BoundCheckBoxField(True)

DFActive.Key =

"Active"

"Active"

Me.WebDataGrid1.Columns.Add(DFActive)

Dim field1 As New TemplateDataField()

field1.Key =

"TemplateColumn1"

"Edit"

Me.WebDataGrid1.Columns.Add(field1)

Dim templateColumn1 As TemplateDataField = DirectCast(Me.WebDataGrid1.Columns("TemplateColumn1"), TemplateDataField)

templateColumn1.ItemTemplate =

New CustomItemTemplate()

'Build Paging

WebDataGrid1.Behaviors.Paging.PageSize = 10

PagerMode.NumericFirstLast

'Build Sorting

'WebDataGrid1.Behaviors.CreateBehavior(Of Infragistics.Web.UI.GridControls.Sorting)()

'WebDataGrid1.Behaviors.Sorting.SortedColumns.Add(WebDataGrid1.Columns("MSecurity"), Infragistics.Web.UI.SortDirection.None)

End Sub

Also when I change pages using the pager I get "Async Request Failed"
