解决方案
保护无效gView_RowDataBound（对象发件人，GridViewRowEventArgs E）
{
DataRowView的rowView =（DataRowView的）e.Row.DataItem;
如果（rowView [ColumnID的]！= DBNull.Value）
{
VAR VAL = rowView [ColumnID的]; }}
//你也可以做这样的
无效GridView_RowCommand（对象发件人，GridViewCommandEventArgs E）
{
//检查是否是正确的CommandName ...
如果（e.CommandName ==添加）
{
//做code
}
}
I have a grid-view and in one column, I added buttons with every row that it is creating a button. What I need now is, if someone clicks on that button I need to get the field of that corresponding row. I have searched for the solution but i can't find out how to do it ?

protected void gView_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataRowView rowView= (DataRowView)e.Row.DataItem;
if (rowView["ColumnId"] != DBNull.Value)
{
var val =rowView["ColumnId"];
}
}
// you can also do like this
void GridView_RowCommand(Object sender, GridViewCommandEventArgs e)
{
//Check if it's the right CommandName...
if(e.CommandName=="Add")
{
// do code
}
}
