Accessing Custom Properties In UI

I am attempting to set my custom properties in the UI I have created for my custom transformation. I can access them in the ProcessInput, but if I try to assign them a new value in my UI the values dont change.



I set the properties up in ProvideComponentProperties

public override void ProvideComponentProperties()

{

// Perform component setup operations

ComponentMetaData.UsesDispositions = false;

// Add Input

IDTSInput90 input = ComponentMetaData.InputCollection.New();

input.Name = "TrimInput";

input.ErrorRowDisposition = DTSRowDisposition.RD_NotUsed;

// Add Output

IDTSOutput90 output = ComponentMetaData.OutputCollection.New();

output.Name = "TrimOutput";

output.SynchronousInputID = input.ID;

IDTSCustomProperty90 Trimproperty = ComponentMetaData.CustomPropertyCollection.New();

Trimproperty.Name = "Trim Values";

Trimproperty.Description = "Selected Trim Values";





IDTSCustomProperty90 Colproperty = ComponentMetaData.CustomPropertyCollection.New();

Colproperty.Name = "Col Names";

Colproperty.Description = "Column Names";



}



btn Click event in UI form



IDTSCustomProperty90 Trimproperty = _dtsComponentMetaData.CustomPropertyCollection["Trim Values"];

Trimproperty.Value = sConcatTrim;



IDTSCustomProperty90 Colproperty = _dtsComponentMetaData.CustomPropertyCollection["Col Names"];

Colproperty.Value = sConcatColNames;



Any suggestions or please point me to any example would be greatly appreciated.
