[DX Support team: this thread was cloned from ASPxGridView - How to determine a data type of GridViewDataColumn at runtime]
This only works if the grid has at least one data row.
If you, like us, send in a dataset with an empty model, the value will be null.
Is there anyway around this?
For future referens:
Visual BasicProtected Overrides Function GetModelType() As Type
Return GetType(MyDataModel)
End Function
Protected Sub PrepareEditForm(ByVal sender As Object, ByVal e As ASPxGridViewEditorEventArgs)
Dim Type = GetModelType()
Dim DataType = Type.GetProperty(e.Column.FieldName).PropertyType
If DataType = GetType(Decimal) Then
e.Editor.CssClass += "decimal "
End If
End Sub
Hello Bengt,
If the ASPxGridView is bound with an empty data source, it knows nothing about value types of the source. I am afraid that in this case the only way to determine data types of columns is to check the data source directly. If the data source provides this information, you can find the same column in the ASPxGridView and set a corresponding default filter condition as demonstrated in the ASPxGridView - How to determine a data type of GridViewDataColumn at runtime ticket.
Okey, I have already planned a Plan B where I check directly against the data source.
Since the fieldname is corrensponding to the property in the data model it should be farily simple.
I added a method in my user control that returns the current data model.
Then I match the fieldname against the data model and check the datatype on the macthed properties
in that model. Works like a charm!
