I have a nested row that I am having some trouble with. I can even hit the On Selected Index Changed method just find. as i step through it, it does everything I am telling it to do and I guress right before it is supposed to hit the On Row Updating method it renders the page.

When I try to edit a row in the nested gridview; I never hit my on Row Updating method. I do have the On Row Updating property set on the gridview, I do have the datakeynames property set. Yep, when I click on Update (next to Cancel) and step through it in VS It does everyhing...

The Edit, Delete and Insert events work as I expect. The markup and code behind are as follows: "The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. The Row Update event will load a copy of the product table from the database after successfully updating a row.

Hi cpkilekofp; I removed the Insert command button and put in an event for Command to see if the Update button press in the grid View control would trigger the Command event - it did not. My markup and code look as follows and the Update event is not firing: Hi cpkilekofp; I removed the On Row Updating from the Grid View definition - to no avail. David I added a stub for the grid View Row Command event and set a breakpoint. Placed breakpoints at Row Command, Row Editing and Row Updating. Much thanks to cpkilekofp and informaniac for their time and effort in trying to debug this problem for me.

Hi all, In On Row Updating function I am updating the values of Data Table object and calling Bind Data() of the Grid View. That still shows the data in edit could be the problem?

The routine loading of the product table now happens only on the first pass through the code behind.
