C# – cancel gridview row edit mode programatically using C#

If you don't need to read only mode, in that case you can put input boxes ( textbox, dropdownlist, etc.) in ItemTEmplate section and bind them with existing data.

Next, put a submit button at above/below of the GridView and handle button Click event and loop through the GridView item data and save all database.

I'll post code block if you need. Thanks for your time.

From what I understand, you are just trying to remove the edit/update buttons from inside the grid to an external location.

You can programmatically set the edit index of the grid, by setting it's EditIndex property to the index you want. You can of course base this decision on the currently selected row of the grid.

After that, you need to databind the grid and change your button from "Edit" to "Update" (if you are using a toggle like solution) or enable/disable them as needed.

The logic for the update can then use the UpdateRow method on the Grid to persist the changes. You can follow the example here to see how to force the edit programmatically. In your case, on button click, you need to pass in the current edit index, like this:

myGrid.UpdateRow(myGrid.EditIndex, true);

EDIT:

I completely bypassed the fact that you want the edit to happen on row click, and that is not as easy to do since clicking the row will not cause a postback. You can probably use something like this to that effect. It basically boils down to setting a client side event on the entire row at creation on the server. I have not tested that though, and I personally think that part alone should be another question entirely since it can be isolated to "how to cause a postback from a row click of a gridview".
