Gridview edit not updating

I have specified Data Key Names as Auto ID, the primary key of the database table.

Then I have several methods attached with following events Get video of hundreds of ASP. On Row Editing - Edit Record On Row Cancel Edit - Cancel Record On Row Updating - Update Record On Row Deleting - Delete Record As I set Auto Generate Columns property to false so I am going to manually write the fields name that I need to appear in the way I want.

Thus any renderer which attempts to modify the meta Data will FAIL!! If you look at the 'handle Update' method for that line you will see that it cannot work as coded. Edit a cell in the hex column and it will crash while trying to update the background color in the adjoining column. Table passes 'null' for the meta Data object when it calls the renderer. I wish there were more tutorials explaining the way to build these plugins and mixins.

Format Exception: Input string was not in a correct format.

This demo is a continuation of my previous example “Binding Grid View with Data”. When I do an update, and get to the Grid View1_Row Updating, there is no value passed to "ID", and then when I go to the next row for "Company" I get the following error: Specified argument was out of the range of valid values. Text; bit when ichange it to string id =((Text Box) Grid View1. Line 136: Source Error: Line 134: string Um = ((Text Box)Grid View1.

So I have to specify how I want them to appear in the normal view and edit view.

That’s why I have placed different templates like Item Template (for normal view) and Edit Item Template (for edit view).

Table) is passing "null" as the meta Data object which need to be modified. Just could not figure out why the renderer was being called with the meta Data argument = null.

I am pretty sure it is a bug as the statement it crashes on (shown above from 'handle Update' in
