VB.Net Checkbox values
in [Dot Net]
|
From: LionsDome on 5 Dec 2007 10:00 Hello, I have a vb.net page which a bunch of checkboxes. A user can select a checkbox(s) and hit the submit button to store those values in a SQL Server table. This works fine with no problem the first time the user submits. However when user submits a second time while changing some of the selected boxes the page only re-submits the previosly selected checkbox values. It's like its storing it somewhere in the cache or something. My page is ready to launch but cannot for this reason alone. Any ideas as to what is going on here? Any help would be greatly appreciated. Thanks. Anil

How are you repopulating the the controls on the round trip when the user hit's the Submit button, and the value for a control has changed?

The values are saved to the database and the values based on the selected checkboxes get repopulated when the page is loaded. I set the ViewState for all the checkboxes on the pages to false and the Page.ViewState to false on page load and I am still unable to get it to work. Am I missing something here?

Is the repopulation of the control being done at PostBack from the database, and you sure data is being saved to the database?

You can select a few checkboxes and hit the submit button and the values get saved and the page is then reloaded. When you hit the submit button a second time and select different checkboxes for soem reason the same checkboxes that were selected in the first goaround are the only ones that get updated into the table. Each submit clears out the table for that particular record id (We have upto 6 different record Id's that user can select from the dropdown) so I know for a fact that the same ones are getting populated over and over again. Based on your suggestion, I set the Viewstate property to false for each checkbox on the page and also set the page viewstate property to false. I hope I was a little clear in helping you to understand my problem. Thanks for taking the time out to help me thru this. I really appreciate it a lot. Anil |
