Detailsview updating newvalues
Now, we have Edit button on Details View control in ASP. When we click Edit Button that time we need to change mode of Details View control for Editing Records. For Editing set Autogenerate Edit Button = True at property of Details View control.Also note that group ordering, however, is handled by editing the form, selecting the groups tab and reordering the group's in the list. You can use the filters above the element list to show only the elements you are working on.The "Full element name" field shows the text that you should use to access the element when using placeholders i.e.write code at Item Deleting Event of Detials View control for Delete record from Detials View.(template column) to edit database with some data source control like Sql Data Source, Access Data Source, XMLData Source, Object Data Source or Site Map Data Source, it is possible to get an error like this: Cannot insert the value NULL into column 'Column Name', table 'Database Name. Eval method only send data to page, but you can't receive updated data back.Let's say we want to add the values in two elements together, element1 and element2 and put the results in an element called 'total'.
