Hello,

I have a webdatagrid bound to a SQLDataSource.  Table looks like below

ControlNum           SubNum          MyDate

20100617.02              1                     06/25/2010

20100617.02              2                     06/30/2010

20100617.02              3                    07/14/2010

20100617.02              4                     06/08/2010

When I want to delete a row (for example row with SubNum=2),  I can delete fine and everything works great.  Now the number of rows left in the table is three (SubNums: 1, 3, and 4 are left) 

Right after I delete I would like to edit the rest of the SubNums so that the row where Subnum =3 is changed to =2.  and row where SubNum=4 is now =3.  The Grid then should look like this:

ControlNum           SubNum          MyDate

20100617.02              1                     06/25/2010

20100617.02              2                    07/14/2010

20100617.02              3                    06/08/2010

I would like to do this in Javascript.  I have come up with the below code but for some reason after I delete the row and try to change the Subnum it  will give me error "this._props is null or not an object"

script type="text/javascript"

var selectedDataKey = "";

var changed = false;

function onRowSelectionChanged(sender, eventArgs) {

var rows = eventArgs.getSelectedRows();

var selectedRow = rows.getItem(0);

selectedDataKey = selectedRow.get_dataKey();

}

function DeleteCorr() {

var answ = confirm("Are you sure you want to delete this correspondence?")

if (answ) {

if (selectedDataKey != "") {

var grid = $find("<%= wdgSubmission.ClientID %>");

var rows = grid.get_rows();

var row = rows.get_rowFromKey(selectedDataKey);

var subnum = row.get_cell(1).get_value();

var sub = subnum-=1

var rowl = rows.get_length();

rows.remove(row, false

);

if (subnum < rowl) {

for (var x = sub; x <= rowl - 1; ++x) {

var cgrid = $find("<%= wdgSubmission.ClientID %>");

var crows = cgrid.get_rows();

var crow = crows.get_row(x+1);

crow.get_cell(1).set_value(x+1);

}

}

}

else

{

alert("

Please select a row to remove.");

}

}

else {

}

</

script>

Thanks!
