Problem I have is when I call a Java Script function in the first row of the grid.

[HalconDivino]

Hi how are things

I hope you can help me

The problem I have is when I call a Java Script function in the first row of the grid.

The problem only occurs in the first row of the grid, there is no problem with the other rows

The grid was developed with ItemTemplate with TextBox to capture data

for example I am capturing the data of an invoice in the first row of the grid

If I add the amount of the invoice plus the tax, it does not give me the total

I repeat it is only in the first line the problem

Is there something that can be done
