Number of rows in Unbound Child combo

Hi Andi,

Thank you for the details. I will test that solution.

I found a way around to do what I needed passing Server side data to a hidden control and retrieving it with Client side code.

Your solution may be better than mine.

Number of rows in Unbound Child combo

Hi Ellen,

As I mentioned our your last post before, we cannot get the total of rows count before the WebCombo shows the dropdown list first and retrieve the filtered data. The workaround for this scenario is by showing the dropdown list first then, after that, we can get the total row of its value. In here, I show the total row in a HTML TextBox. Here are the snippet:

function WebCombo1_OnAfterItemSelected(controlId)
        {
            var WebCombo1 = ISGetObject(controlId);
            var WebCombo2 = ISGetObject("WebCombo2");
            var count;
           
            WebCombo2.SetFocus()
            WebCombo2.ShowDropDown();
            setTimeout(function()
            {
                count = WebCombo2.GetRowsCount()
                document.getElementById("Text1").value = count;
                WebCombo2.HideDropDown();
            }, 800);
            return true;
        }

I hope it helps and please do not hesitate to ask if you have any other questions. Thank you.

Best Regards,

Number of rows in Unbound Child combo

I posted this question as a Discussion type, but didn't get an answer. Hopefully after I post it as a Question, I will get a better result.

I populated two Unbound combos: one is a Parent and another is a Child that depends on the value selected in the Parent. Everything works fine except for the Count of rows in a Child combo. I select a value in Parent combo and 12 rows are populated in Child combo, what is correct.

GetRowsCount() gives 50 rows (a total number of rows without a filter). TotalRetrievedRows() and TotalRows() give 0.

I need to know the count in order to select a default value in Child: if Count > 1, don't select anything, if Count = 1, select that value.

Thanks.
