I have a Datatable that I attach as a datasource to a Webdatagrid. The Datatable has dynamically chosen columns with dynamically chosen order. As such I never know which columns will be selected and in which order they will be. I do know the Column headers and would like to format the columns that have currency in their fields to have a $ in front of them and 2 decimals after them. I'm not able to figure out how to do this.
WebDataGrid1.DataSource = dt
For Each col In WebDataGrid1.Columns If col.Caption = "Total" Then
End If Next
I can see
WebDataGrid1.Columns(0).FormatFieldMethod = New FormatRecordItemValue()
But iterating through webdatagrid1 I can't find col.FormatFieldMethod
I can also not find what to pass to FormatRecordItemValue as it constantly tells me I'm entering the wrong value. I tried following the example in
By design if the columns are auto generated, the columns collection is empty. The columns for the grid should be explicitly specified and then DataFormatString can be specified.
I have attached sample to demonstrate this.
FormatFieldMethod property expects a function, which has the following signature.
Private Function FormatFieldMethod(field As ControlDataField, value As Object) As String return "the formatted value"End Function
Let me know if I may be of further assitance.
I am also having this problem.
The link you provided results in 404 error, while the sample I downloaded does *not* show how to use FormatFieldMethod function.
Specifically all samples from Infragistics show how to return 'hello', but do not show how to properly pass values.
Could you please post a code sample of how to use FormatFieldMethod function.
