Draw Image With Rounded Corners / Border And Gradient Fill In C#

Dec 1, 2010

I've looked everywhere and googled everything and couldn't find anything good. What I need is a class that is able to draw an image (graphics) with rounded corners (different on each corner is a plus) with a border and gradient fill.

All the examples I find have some flaws (like bad quality, missing functionality etc).

I will use this with a ashx that will draw the image and then show it to the user.

Forms Data Controls :: DetailsView Jumping To Wrong Record After Clicking Update Button?

Jan 20, 2010

I have a web form with a detailsview controlled by a linkbutton in a gridview. When the user clicks the linkbutton, a panel appears with the detailsview inside it. The select statement is created based on the commandargument of the link button. So far, if there is a record associated with the ID passed through the linkbutton, the detailsview displays correctly. However, if the user needs to update this, it jumps to the default record for that detailsview after clicking the standard update link. Without a default ID set, the detailsview does not display at all, as some IDs do not yet have a corresponding record for the detailsview.

How can I get around this issue? Also - is there a way to immediately display an open detailsview for IDs with no record associated yet?

Web Forms :: Shows Two Button Instead Of One When Clicking On Button

Aug 17, 2010

I have this issue i have been looking at for a while and cant seem to figure it out. I have two ddl's on my page and a InsertCommand from sqldatasource. My InsertCommand is actually updating the foreign key of the two ddl's in another table. When i click on my button it shows two numbers instead of one. The challenging thing now is that i have

DDLName.Items.RemoveAT("itemName.SelectedIndex")

after the insert so it would not duplicate what i am updating. If i take this statement out of my code. it updates well as in showing the one record that was updated. if i put it back in there it shows two records where updated. I tested my sql statement and its working fine meaning it shows only one record is updating.

Forms Data Controls :: Changing Image In Image Button Column In A Datagridview?

Oct 21, 2010

Just wondering if anyone has ever managed to find a way to have a datagridview image button column in a template field which display different images on different rows depending on some data element in the row. Our application needs to display a series of fees charged against an account column which will be either less then 500, 500 to 1000 or >1000. Some of those fees are charged at a full rate, others at a partial rate, and some are not charged at all. The user would like to see a simple 3-state graphic which would convey the simple info: full-charge, partial-charge, or no-charge. Sounds easy enough but I've not yet managed to find a way to do this. Every time I attempt to modify the individual cell's graphic it seems to want to change the graphic for all the rows.
