DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

Quote:
ClsClientReg obj = new ClsClientReg();
obj.DeleteClient(int32Id);

If the first line creates (as it looks) an empty object, the second line is destined to fail.

Solution 2

The Gridview datakeys collection seems to be empty.

Set the DataKeyNames property and then access it.
