what is the meaning of this in rowindex (<>-1) ?
I guess it’s index of datarow in datatable. And check it if the datarow exists in datatable like the following expression.
rowIndex = dt.Rows.IndexOf(varDataRow)
Then check rowIndex <>-1
It seems rowIndex is not related with. If you have amnother problem, please raise a new topic for those who face same issue.
