Populating a display form from ComboBox Selection

(0) ShareShare
ReportReport
Posted on by 12

I have been working on this for two days without success.  I have a Display Form with a DataSource of "Materials"  I also have a ComboBox6 with Items of Materials.MaterialsTitle.  The Item for my Display Form is ComboBox6.Selected.  I just can not get the other fields to populate in my Display Form by choosing a title from my ComboBox.  I've tried the combobocx inside and outside a data card, made sure all the data cards are set to ThisItem.[field name] and DataFields are correct and the values are set to Parent.Default.  Nothing I try works!  All I'm trying to do is populate a display form with the other fields in a table when I select the title field in the combobox.  Any and all help is appreciated!  TIA

    Hi @gnott,

     

    The combo box should be outside the form and the Item property of the form set to:

     

    LookUp(Materials, MaterialsTitle = ComboBox6.Selected.Value)

     

    The above works if MaterialsTitle is a text type column. If it is a Choice or LookUp type, the formula for the Items property of the form should be:

     

    LookUp(Materials, MaterialsTitle.Value = ComboBox6.Selected.Value)

    If your datasource is SharePoint, use LookUp(Materials, ID=ComboBox6.Selected.ID) as the Items property of the form.  I suggest you make the Items of the combobox Materials and put MaterialsTitle as the field in the window.

    @BCBuizer  Thank you!!  Not exactly what you said (and I'm curious why my eventual solution works) but I played around with it until it did work.  The eventual solution is 

    LookUp(Materials, MaterialTitle=ComboBox6.Selected.MaterialTitle)

     

    Thank you for the assist!  MUCH appreciated!

    @Drrickryp  Thank you!  It was the Lookup that put me on the right track.  My eventual success was LookUp(Materials, MaterialTitle=ComboBox6.Selected.MaterialTitle), but your comment and @BCBuizer 's led me to the solution.

    Hi  @gnott ,

     

    Indeed the column title should have been selected as you found out yourself. Glad to read you found a solution.
