Extending GridDataItem

[Gregory]

Hello, I am migrating a control from GridView to RadGrid. With GridView, I was able to extend the GridViewRow class:

Public Class GridViewSearchRow
Inherits GridViewRow

    ReadOnly Property SearchValueEntry As ISearchValueEntry
        Get
            Return FirstChildControl(Of ISearchValueEntry)()
        End Get
    End Property

    Public Sub New(…)
        MyBase.New(…)
    End Sub

End Class

In its containing grid (an extension of GridView), I was able to instantiate my custom row by overriding GridView’s CreateRow function:

Protected Overrides Function CreateRow(…)As GridViewRow

    If rowType = DataControlRowType.DataRow Then
        Return New GridViewSearchRow(…)
    Else
        Return MyBase.CreateRow(…)
    End If

End Function

In Telerik, I am able to extend the GridDataItem class:

Public Class RadSearchRow
Inherits GridDataItem

    ReadOnly Property SearchValueEntry As ISearchValueEntry
        Get
            Return FirstChildControl(Of ISearchValueEntry)()
        End Get
    End Property

    Public Sub New(…)
        MyBase.New(…)
    End Sub

End Class

 

 

Is there a similar way to ensure that all objects in the .Items() collection are added as RadSearchRow? I’ve noticed that the RadGrid’s GridDataItems are created within the CreateChildControl() sub, but since CreateChildControl() isn’t a function (like GridView’s CreateRow) I’m not sure how to mimic it.

Thank you very much.

Hello Gregory,

Unfortunately the RadGrid control does not provide such an option. Possible solution could be to inherit the RadGrid control and the new Grid to use your GridDataItems however this is not a supported scenario and we could not guarantee if this will covers your requirements.
