I have succeed to do that, but the problem that I want the paging to be effected? If page one of the grid has a rows that will be hided so page two take its place.

I am not sure you can implement it this way. However, there is another approach.

I have a aspxgridview with details row.
in detils row of this gridview, there are about 10 aspxgridviews. whenever one of this grids cause callback by clicking edit/new/delete , other gridview also databound i.e hit database. this cause performance issue.
Is there a way to disable databinding on other aspxgridview?
tanks.
You can use tab content lazy loading. Look here for example and here for further explanation.
i find a solution here:
ASPxPageControl - Page Load of all TabPages
I have a gridview and for each row, I have updated a specific column's value.
However, I need to do this on pageindexchangedevent and I have wired up the code for this, but it does event does not break (I have a breakpoint)?
What is the best way to change a gridview's values when the page has been changed?
You can do your code on the grid view row data bound.
I have a gridview in ASP.nET and I have a "Select" command field. What I want to do is that when the user click on on the "select", I would like to take the selected row and do some calculations and rebind the original gridview with updated the row.
How can do this?
Thanks.
// do your thingy
DataGridViewName.DataBind();
There are a lot of places where grabbing the row is already explained. Take a look at this Link. You have to call the bind data method on the grid after your calculations. If you want to modify just that row, I would think you modify the source data collection for that row and rebind.
This link may also help. Instead of Edit, you could have Select.
Ok, i have a gridview and on page load, i dynamically add a column to it that contains a link control. this link control has a onclick event associated with it so that when its clicked, i want to do some processing. Now I have noticed that if I just bind the grid the first time (i.e. if(!IsPostBack) and have enableviewstate for the grid to be true, clicking the link in that column, doesnt trigger the onclick event. But if I bind the grid on every postback, everything seems to be working..does anyone know the reasoning behind it?
It happens because you're dynamically adding the column, so on every postback the column has to be created. What you may want to do is to look at Creating a Custom Column.
May be creating the row Id solves your problem. Check out this link and the post marked as answer.

I have created a GridView whose columns are dynamically created based on my data source. I have implemented these columns by using the approach described here.Those columns display properly on the initial load. However, I need to implement commanding so that a user can edit / delete a row in the GridView.
At this point, I have implemented commanding as I would with a normal GridView. I have a TemplateField with an ItemTemplate that has LinkButton elements for edit and delete. The CommandName for each LinkButton is set to either Edit or Delete respectively.
Oddly, when a user clicks either the Edit or Delete link, the data in the GridView disappears. However, I have verified that I am in fact re-binding the data when one of these LinkButton elements is selected.
Can anyone provide some suggestions as to what the cause could be?
Thank you!
Here are good examples. You can figure out postback issue.
