Hi,

I'm removing rows from a gridview using Table.Remove( ). This removes the 
rows from the gridview.
But the problem is although it removes rows from the gridview it doesnt 
update the Gridview.Rows.Count to return correct number of rows remains on 
the gridview. Instead it always returns the number of rows gridview 
originally had prior to removing them.

Anybody know why this is happening? How to remove gridview rows in a manner 
so that it will update the rows.count property correctly?

Note: I'm looking for a method to directly remove rows from a gridview 
without having to rebinding gridview to datasource controls etc...

Dev

What is Table.Remove()? What class is Table? How is it related to the grid?

Hi Goldin,

Just check the object returned by Gridview.controls(0). This is a Childtable 
which you can typecast to Table.
Using this you can add new rows, delete rows (as I've mentioned) in a 
gridview directly. Let me know if u figure out how to overcome the problem 
I've mentioned below.

That's not the way of removing rows.
Gridview.Rows.Count does not return Table.Rows.Count!

Gridview.Rows.Count is for the DataSource's row-count.
Well, you cannot control the items that will be pushed in the grid if you 
cannot control the data-source.

If you want to remove any item, ensure that you also remove it from the 
datasource to which you are binding the gridview.

Hi Gaurav,

Thanks. I'm trying to do this in ASP.net and gridview is bount to a 
datatable. I dont need to use a datasource control in this case as I'm not 
trying to delete any rows from the database.

How to remove rows from the source datatable on postback?

Do I have to access database on postback, recreate the datatable without the 
rows I want to get rid off and bind the datatable to the gridview is it? If 
so it doesnt sound a good method for me as I dont want to access the 
database unnecessarily.

Any ideas?

Dev

You may bind the datagrid to DataView with a "Filter" with appropriate 
"SortColumn".

DataView will not modify the underlying table but at the same time will be 
able to "Filter" the data to be given to the grid.
