Changing column name dynamically

Question

I have a Header / Detail custom screen where I\'m manipulating which grid columns display based on a dropdown selection in the header. This works fine, but now I\'d like to

Answer 1

You can refer below example to dynamically change Grid Column Header.

Below example works with Screen PM401000 – Project Transactions Inquiry

public class TransactionInquiryExt : PXGraphExtension<TransactionInquiry>
{
    public void TranFilter_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected baseInvoke)
    {
        if (baseInvoke != null)
            baseInvoke(cache, e);

        PX.Objects.PM.TransactionInquiry.TranFilter row = e.Row as PX.Objects.PM.TransactionInquiry.TranFilter;

        if (row == null) return;

        PXUIFieldAttribute.SetDisplayName<PMTran.description>(Base.Transactions.Cache,
            row.ProjectID.HasValue ? "Description for Project Tran" : "Description");
    }
}

Make sure to set RepaitColumns property to True of PXGrid Control.

Your display name routine looks correct however to make sure the column names actually update you need to do the following:

• In the page source, you need to set the "RepaintColumns=true" value on the grid. This can be done via customization manager or directly from your ASPX source. - This tells the grid to refresh the columns after a callback allowing the headers to actually redisplay.
