View 8 RepliesTreeList RadControl : No Records To Display
Jun 1, 2011As I have to test some RadControls components for my company, I'm currently working on the TreeList control. Even if I only try to do basic stuff (populate the control with a database query) It doesn't work and I just can't figure out why !My previous investigation lead me to think that issue is related to DataKeyNames and ParentDataKeyNames properties but I'm not sure.So instead of talking about my work, I'll let you get an code snippet so as you can take a look at it :

VBSQL.OCX Is Failing While Loading Flat File Data (text File Data)?
Oct 15, 2009Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"
View 1 RepliesWhat Event To Use When Loading Initial Data
May 23, 2011I'm writing a forms application. I'm adding a piece that allows you to double click on a row of a datagridview control to open a new form with more details. These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?
