Indeed, I used the ItemTemplate and now I can edit. Thx ;)

Don't know if this is exactly what you're searching for, but did you check http://msdn2.microsoft.com/en-us/library/system.web.ui.webcontrols.objectdatasource.selectcountmethod.aspx

I stumbled upon it yesterday although I didn't need it, it was in the back of my head. Looked it up again for you: http://msdn2.microsoft.com/en-us/library/aa479353.aspx You'll have to combine several pieces of the page, but I think it's all there ;)

Could you be a bit more specific on what doesn't work? Also be sure to check Asp.net's membership system: http://aspnet.4guysfromrolla.com/articles/120705-1.aspx http://msdn2.microsoft.com/en-us/library/yh26yfzy.aspx Once I got it to work with my (non-sqlExpress database) it worked like a charm.

My page contains a gridview that gets it's data from a method. De data comes through, but the grid is uneditable. I need the user to be able to check/uncheck checkboxes and thereby trigering an update method. I tried with assigning an objectDataSource and with dynamicly assigning a datatable source. Both gave the same result. What am I doing wrong?

Short ----- I need to catch an OnCheckChanged from a gridviews' checkbox that gets filled by a DataTable. Long ---- I have an ASP.net page with C# codeBehind. In it is a gridView that gets filled by a DataTable. There happens to be a bool in one of the columns. I want the user to be able to check or uncheck these checkBoxes. But there is no onCheckChanged listener exposed on the CheckBoxField control. The CheckBox looks like this: I thought I could go for an ItemTemplate column like this: But this column doesn't get it's data from the DataTable, so I tried to fill it manualy with the OnLoad event OnLoad="loadPermissionCheck" but this doesn't seem to get triggered. Hope I made myself clear enough. If this post happens to fit better in the ASP.net corner, then please move it. I wasn't sure. -- modified at 7:45 Wednesday 30th May, 2007
