On gridview editing event I have :
string name = GridView1.Rows[e.NewEditIndex].Cells[1].Text;
string subname = GridView1.Rows[e.NewEditIndex].Cells[2].Text;
I want to get those values from variables in row updating event gridview but I don't know how to access them.
thanks
Use the RowIndex property
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
GridViewRow row = GridView1.Rows[e.RowIndex];
string name = row.Cells[1].Text;
string subname = row.Cells[2].Text;
}
To get the old/new values of an updating row, you can also use the GridViewUpdateEventArgs.OldValues and GridViewUpdateEventArgs.NewValues Dictionaries.
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string oldName = e.OldValues["Name"];
string oldSubname = e.OldValues["SubName"];
string newName = e.NewValues["Name"];
string newSubname = e.NewValues["SubName"];
}
To detect only the changed values(not tested):
var changed = new Dictionary<Object, Object>();
foreach (DictionaryEntry entry in e.NewValues)
{
if (e.OldValues[entry.Key] != entry.Value)
{
changed.Add(entry.Key, entry.Value);
}
}
or with LINQ:
changed = e.NewValues.Cast<DictionaryEntry>()
.Where(entry => entry.Value != e.OldValues[entry.Key])
.ToDictionary(entry => entry.Key, entry => entry.Value);

You can use the code:
protected void Page_Load(object sender, EventArgs e) { //The Name is string display on screen and name is variable used . //The Subame is string display on screen and subname is variable used .
Response.Write("The Name"+ name );
Response.Write("The Subname" + subname);
}
