Re: Is there a method to change a text box back to it's original state? Dave Kreskowiak26-Oct-07 12:36 Dave Kreskowiak 26-Oct-07 12:36  Though I've never had to reset controls back to a known state, (I tend to destroy and create entire forms instead) that's a trick I'll have to put in the bag.

Come to think of it, it more resembles a Heap, difficult to enumerate...

BiG RaLpH Re: how can I read 4 hex characters from a textbox and put them in a uint? Luc Pattyn26-Oct-07 6:53 Luc Pattyn 26-Oct-07 6:53  Hi, you could: 1. use long.TryParse() and then split the long in upper and lower halfs. 2. split the string in two parts, and use int.TryParse() on each of them. The second method may be more difficult since it may have to cope with varying string lengths when leading zeroes are omitted in the string.

This is the top level event exception handler that is capable of catching exceptions. Then, you can simply extract the stack trace of the error that caused this.

When I start my application I see the results in my gridview. When I clic on edit and chanche some value and click on update it wil give me this error: ObjectDataSource 'ObjectDataSourcePersoon' could not find a non-generic method 'Update' that has parameters: naam, tussenvoegsel, achternaam, adres, woonplaats, telefoonnummer, original_id, Original_naam, Original_tussenvoegsel, Original_achternaam, Original_adres, Original_woonplaats, Original_telefoonnummer. check here my dataset update method Does someone know whats the problem?? Re: Error in my dataset kubben26-Oct-07 3:39 kubben 26-Oct-07 3:39  Your objectdatasource needs to have a update method that has the parameters that you see in the error. IN that method you should run a sql statement that updates the sql database. You perhaps have put an update method in your objectdatasource definition, but it probably doesn't match the one defined in the error. NOTE the columns are auto generated based off the columns in the gridview. Hope that helps.

See it here: click here One DataGridView, one bindingsource, multiple tables lsconyer26-Oct-07 3:12 lsconyer 26-Oct-07 3:12  Hello all. I have a datagridview (genericGrid) and a bindingsource (genericBS). genericGrid's datasource is genericBS. I want to programmatically switch genericBS's DataSource and Datamember. Then, display those values on the genericGrid. What I've tried: Using a switch statement to change genericBS's DataSource and DataMember properties on the load. Then, called genericBS.ResetBinding(true). This is supposed to force genericGrid to refresh its rows. Amazingly, it doesn't work. What actually works: I've resorted to creating a bindingsource for each table. Then using a switch statement to change genericGrid.DataSource. This works. But, there has to be a way to use just one bindingsource, right? Any suggestions?

It is kind of silly, but it the only way I know of to get the enums numerical value. I am sure someone else will post a different way of doing it, but that is the way I normally do it.
