"Deleted row information cannot be accessed through the row." WHY!!
hi guys, I have a problem with my datagrid. My form is set up so I have two textboxes an add button and an editable datagrid. The datagrid is bound to a datatable which is in my cache.When I click the add button the contents of the textboxes are insertedinto the datatabel in teh cache and the datagrid is bound to it.
However the problem comes when I delete a row from the database and then add and edit a row. Lets say my datagrid has only one row, I delete it and then insert a new row. WHen I click on the Edit button of the new row that has been inserted I get the following error
Delet...adding / deleting table rows, and accessing controls within added rows
Hi everyone,I would like to know what is a good and simple way to achieve this using asp.net. Basically i would like the ability to add and delete rows, preferably table rows. Against each row is its delete button, hitting it will delete the corresponding row. There is only 1 Add button to add a new row. In each row, there are say 2 textboxes. When i hit, say a calculate button, i wish to be able to access all the available textboxes in all the available rows in the event handler, and say just output a sum.If GridView is suggested, could you please explain why i...accessing row by row

When datawindow row 1 is clicked and selected then a pfc_deleterow is issued
all dw rows are deleted. dw_1 update spec is "update", not delete then
insert. Only one key column on the table which is a serial column.
ll_rtn = dw_1.event pfc_DeleteRow()
ll_rtn count does indicate that all rows were deleted.
If any other row is selected then only the selected row is deleted. When the
window is 1st opened and row one is displayed but not selected, only row 1
is deleted. Is this the expected behavior?

I faced a problem. I have a simple datagrid. It allows user to select a particular row of data say row 5. It works completely fine but if user wants to delete row 7 when row 5 is selected, the datagrid will delete 5 (which is the selected row) instead of 7. How to go about this issue?
Can't you just select row 7 and delete it?Thanks!Bernie
At first, DataGrid deletes nothing. It sends out only commands that your code has to handle. You have to use DeleteCommand event of datagrid. In this event you have to take the row index from event...Delete a row and all other rows thats linked to it
