Hi,

I hit error below if I set a GUID field as browse search field. This search field is also set to use combobox - Business Object.

Please advice.

Thank you

InvalidOperationException
 The input value could not be converted to the output type.
FormatException
 Guid should contain 32 digits with 4 dashes (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx).

No, I don't meant that.

OK, I have a field called VendorID which is GUID field type.

I add this field as browse dialog search field, ComboBox - business object (VendorsBO.FillAll()). I would hit error when I click on browse button.

After some debugging, I found that, TopMostItem.TopMostValue is always defaulted as "-1" when combobox is created (as shown as below). When program try to convert TopMostValue to GUID, it hit error.

Do you get what I meant?

Please advice

Change the "-1" to "{00000000-0000-0000-0000-000000000000}" and give it a try.  I have not tested this, but a -1 cannot be converted to a GUID.

Hi,

I cant test on it because my project no longer working after I compile SF source code. I got to reinstall SF.

Hi,

I am able to "hijack" the value of TopMostValue to change it from "-1" to "00000000-0000-0000-0000-000000000000" and it would work.

I would wait for your next update.

Thank you

We would have to test this on the GUID as this was not designed with this in mind.  You can just create your own top most item instead of using the property.

Hi,

Which event should I place the code to create my own topmostitem?

Do you meant to modify SF source code?

Thank you

No, do not modify the SF source code.  I was referring to adding an item to the data source that is shown within combo.  Just another another item.

Sorry, I am lost.

Why to add another item to my datasource? My PL field is GUID. How to assign "-1" ? hmm... didn't get you.. sorry.

To add your own item, you would need to handle the DataSource changed event on the ComboBox.  Within the event, you can add a new record to the top of the data table (.Insert() it rather than .Add() it).  You can check the structure of the table for the field names, but it should only have two columns... a "display" column and a "value" column.  Then, just set the values in the new record and insert it into the table.

Hi,

May I know if this issue been handled natively in upcoming update?

Thank you

Hi,

Since the combobox in browsedialog is created at runtime while ShowDialog() method been called, how could I handle its DtaaSourceChanged event?



Also, FYI, the error is occured at ListControl.PopulateComboFromBusinessObject().

Hi,

I found that this issue has been fixed in version 1.6.1.

I specified {00000000-0000-0000-0000-000000000000} in Top Most Value under Combo-General.

After I select item from combobox and click search, I hit error error below. Any ideas?



InvalidCastException

Conversion from type 'Guid' to type 'String' is not valid.

The processing of the where element for GUID was assuming that the type could be cast or converted to a Guid, so I changed it so that it would use the Guid constructor and pass over the value.ToString() (the Guid constructor will then parse the value back into a valid Guid).  So, it should fix the problem you're having.  However, if you need the fix before then, then you can change your source code:

BrowseDialogwindow.vb line 2207:

loFieldValue.Add(New Guid(_CurrentValue.ToString()))

Instead of the:

loFieldValue.Add(CType(_CurrentValue, Guid))

Hi,

Thank you answer.

When would next SF release? I am using SF 1.6.1 (posted at forum) which doesn't have source code. Therefore, I am not able to change my source code.

I am not positive when the next release will be... we are currently getting our finishing out the rest of the posted bugs and getting the install ready for VS2008 and 64-bit.

Hi

Sorry, I still don't know how to solve this problem.

Where should I put my code? How to set Browsedialog combobox.topmost to Guid.Empty instead if '-1'?



Thank you
