ComboBox Value Change won't update UI

I have dug through some other posts and I still am blind to what I am missing. I am setting the value of the FromWarehouse on the Issue material screen in Epicor. I have the following code that properly sets the value of the field but I can’t get the dropdown to update. If I click the arrow of the dropdown the UI fires and it shows the selected value without me needing to do anything. Does anyone know what I am missing?

EpiUltraCombo txtFromWarehouseCode2;
txtFromWarehouseCode2 = (EpiUltraCombo)csm.GetNativeControlReference("d8cbd6bd-beed-4ca7-803c-f5a1023e4bbd");

txtFromWarehouseCode.Value = toWarehouse;
txtFromWarehouseCode.Text = toWarehouse;

Hi @bfraseraepl if you take a look at the Customization User Guide

it details how this works
Also there are many examples in this forum if you search for epidataview

Thanks for the reply. I was misunderstanding that I had to update the dataview as well. Now that I understand that I can see the numerous examples. I’ll give it a try - thanks again.

I reviewed the code in the Customization guide but I am still missing something. My text field updates but my combo doesn’t until I click the UI. Below is my code changing the dataview:

IM.dataView[IM.Row][“FromWarehouseCode”] = toWarehouse;
IM.dataView[IM.Row][“FromBinNum”] = toBin;

I see in the documentation it talks about a Notify. Is that triggers the drop down? I don’t appear to have to do that to get the text field to work.

				EpiUltraCombo txtFromWarehouseCode;
				txtFromWarehouseCode = (EpiUltraCombo)csm.GetNativeControlReference("d8cbd6bd-beed-4ca7-803c-f5a1023e4bbd");					

				DynamicQueryAdapter dqa = new DynamicQueryAdapter(oTrans);
				QueryExecutionDataSet qeds =  dqa.GetQueryExecutionParametersByID("IssueMaterialHelper");
				qeds.ExecutionParameter.AddExecutionParameterRow("JobNum", ToJobNum, "nvarchar", false, Guid.NewGuid(),"A");
				qeds.ExecutionParameter.AddExecutionParameterRow("AssemblySeq", ToAssemblySeq, "nvarchar", false, Guid.NewGuid(),"A");
				qeds.ExecutionParameter.AddExecutionParameterRow("MtlSeq", ToJobSeq, "nvarchar", false, Guid.NewGuid(),"A");

				string toWarehouse = "51REG3";
				string toBin = dt.Rows[0][21].ToString();
				try {
				IM.dataView[IM.Row]["FromWarehouseCode"] = "51REG3";
				txtFromWarehouseCode.Text = "Brad";
				IM.dataView[IM.Row]["FromBinNum"] = toBin;
				//MessageBox.Show("set from bin to Bin");
				} catch(Exception e) 
					MessageBox.Show("Doesn't appear to be picked.");



I was missing the fact that there was a separate field in the dataview for the description. After I set it with the following code it had the desired outcome:

IM.dataView[IM.Row][“FromWarehouseCodeDescription”] = “Job Bin”;
