Client-side delete on server side

[Julia Shah]

Hi,

I have a datagrid that I add/remove rows on the client side and save the results into a database by using following code:

            foreach (GridDataItem item in RadGrid1.Items)
            {
                int PrincipalID = Convert.ToInt32(item["PrincipalID"].Text);
                TextBox box = item.FindControl("txtShare") as TextBox;
                Share = Convert.ToDecimal(((TextBox)box).Text);
                InsertShareIntoDB(PrincipalID, Share);
            }

Adding new rows and updating Share column works fine. What I can't figure out is deleting rows. I am using GridClientDeleteColumn, so when I click on it, the row disappears, as it should. Now on postback, I want to insert into the database only visible (not deleted) rows, but the code above goes through all the rows, even the ones deleted. How can I check on the server-side if a row was deleted?

Thanks,
Julia

Hi Julia,

Please review this code library for more information how to handle the client-side deleting functionality of RadGrid.

Let us know if you need further directions.

Thank you for your reply. Unfortunately, this is not really what I am looking for.

I am not looking for how to catch the deletes on client side, because I am not using automatic update/delete. I am adding and deleting rows in the datagrid on the client side, and then save the whole grid manually on the server side. How can I tell which rows have been deleted after the postback, on the server side?

Thanks,
Julia

Hi,

The grid will raise ItemCommand/DeleteCommand for client-side deleted rows.
