GridView: get selected rows

Below is sample C# code to get selected rows in GridView.

        protected int[] GetSelectedRows()
        {
            List rowIDs = new List();
            foreach (GridViewRow row in GridView.Rows)
            {
                CheckBox cb = ((CheckBox)row.FindControl("chkRow"));
                if (cb.Checked)
                {
                    string IDString = GridView.DataKeys[row.RowIndex].Value.ToString();
                    rowIDs.Add(Int32.Parse(IDString));
                }
            }
            return rowIDs.ToArray();
        }

"SelectAll" CheckBox in GridView using jQuery

Here is a way to do it:

/**
 * Register logic for "select all" check box and the group of check boxes 
 * for each data row.
 * 
 * @param {Object} chkAllSelector     jQuery selector to find the "select all" check box
 * @param {Object} chkItemSelector    jQuery selector to find the check boxes for all the rows
 */

function registerSelectAll(chkAllSelector, chkItemSelector) {
    //"select all" checkbox
    var checkAllBox = $(chkAllSelector);
    //checkbox for each row
    var checkItems = $(chkItemSelector);       
    
    //check/uncheck all rows if "select all" is clicked
 checkAllBox.bind("click", function(){
            checkItems.each(function(){
                this.checked = checkAllBox[0].checked;
                })
        });
        
    //uncheck "select all" if some rows are unchecked
 checkItems.bind("click", function(){
            if(this.checked === false) {
             checkAllBox[0].checked = false;                    
            }
     });                     
}

To use it:

registerSelectAll(".chkAllHeader input", ".chkItem input");

"An unexpected error occurred." accessing Network Connection's properties

Cause: seems like it suddenly happens after a recent Windows Update. I cannot ping or "remote desktop" to the computer. Trying to access network connection give me this error: "An unexpected error occurred."

Solution:
This seems to fix the problem:
command line:
regsvr32 netshell.dll
regsvr32 ole32.dll
reboot

Then I can access the properties page, and I disable/re-enabled firewall. Everything coming back to normal.

P.S.
Keep my fingers crossed. Waiting for more surprised from next automatic Windows Update.
