Detailsview updating newvalues empty

If you click the same header again, the data is sorted in reverse order.You can move to another page in the grid by clicking the numbers at the bottom. Click the Edit link for one of the genres, change the name in the text box that has appeared, and click the Update link. Remember, there’s a script file in the control that should open automatically (if it doesn’t, click the gray arrow on the upper-right corner of the control or right-click the control and choose Show Smart Tag), check all the available check boxes, shown in Figure 13-4. The links in the left column enable you to edit, delete, and select the relevant genres. If you don’t see the Planet Wrox database listed here or you get an error, refer to the preceding chapter, which explains how to set up the database.I want to do something simple like this: form View.Data Bind(); All the examples i've come across show a declerative data source being used.Along every row in Details View control I have one button control, for which I want, when I press one of the buttons (for example, first button which is placed along first row), that value in that first row of Details View gets greater (or smaller, whatever) value, and that value must be stored back in database.Basically,the menu will be like this, Categories Sub Categories.

Here is a code of My Detail View_Item Updating: All the other things like connection string , select and update statements and the layout of detailsview I set in the code behind.I get 0 values for Old Value and New Value in Item Updating event, even though i try to update any row.Andwhen one of these command buttons is cliked it must go to proper page.First, look at the markup for the attribute in a different location. NET controls, the order of attributes in the control declaration doesn’t matter.A couple of interesting things are worth examining. You normally only need these if your column or table name contains a special character such as a space or the name matches a reserved word.I can get the information going through the cells by parsing the html but that smells Form View Update Event Args always has the Old Values and New Values collection empty.(Keys is too).
