Update of Calculated Columns

[Bernd Mueller]

I have a calculated column (a) as the sum of two other columns ((b) and (c)) - editing the value of one cell (eg. (b)) doesn't change the calculated value of the calculated cell (a) - what do I have to do to force the recalculation?

Hello Bernd Müller,

As I have already answered in your other support ticket for the same question, there is no need to manually update the Expression column when changing some of the dependent values. RadGridView should refresh itself automatically. There could be something specific in your scenario, which causes the undesired behavior. I am looking forward to receiving your sample project in the support ticket.

Let me know if you have any other questions.

All the best,

Thanks, it works now.

There was a misstyping in the column name so that the expression could not be evaluated correctly.

 

For i As Integer = 1 To 2

 

 

Dim col As New GridViewDecimalColumn("Col" + i.ToString())

 

RadGridView1.Columns.Add(col)

 

Next

 

 

Dim colCalc As New GridViewDecimalColumn("ColCalc")

 

colCalc.Expression =

"Col1+Col2"

 

RadGridView1.Columns.Add(colCalc)
