Hi,
I hit error 'Input string was not in a correct format' when click search in browse dialog.

[u]Steps to repduce[/u]
1. Drop browsedialog on to form.
2. Specify search fields. Try to have search field that similar with below.
Search Field 1 : Textbox, String, Visible = true
Search Field 2 : Combobox, Integer, Visible = false
Search Field 3 : Textbox, String, Visible = true
3. Specify other properties.
4. Run the form, click browse button, and click search in browse dialog.

Error below would be occurred. The error happen if I have non-character search field set to [b]invisible[/b] at the middle of other string search field. It works fine if I move search field 2 after search field3.

FormatException
Input string was not in a correct format.

It sounds like you have an InitialSearchValue in the text box that is not visible that is not a number but represents a numeric field. The stack strace shows that the BuildWhereElement is trying to convert the text value into a number. Since you are receiving an error then there has to be a value in the textbox. If it is not visible, then it would have to have been set in your property sheet and you must have provided an initial search value (this can be done programatically as well). When you rearrange the fields, the search values are cleared out....thus you do not get the error.
