i think you need to bind the listview again when select the value from droupdown list. then may be you are not face the same problem.
hope this help.

I am trying a very simple thing. I have 3 textboxes and 3 labels. On text change i am setting the content of label.
The issue is when i insert some value in 1st textbox(e.g 50) change the focus to another textbox the values in label is reflected perfectly.
But the focus which i setted on 2nd textbox is lost. And the focus is lost somewhere.
I need to click again on 2nd textbox to get focus.
The same issue is reproduced if TAB is clicked to change focus.
I have made a small demo project for the same and attached. You can avail that from the below link

This is a rather common issue in ASP.NET, as described here: http://www.codeproject.com/Articles/17571/Maintain-focus-between-postbacks-in-ASP-NET-2-0-al or here: How do I maintain focus position in UpdatePanel after page partial post back. Those links also contain some suggestion on how to solve this issue.
One of the possible solutions is to keep track of control with focus, put information about it into a hidden field and manually restore the focus after postback. This method is described in the first link mentioned.
I have a form with one gridview as master linked to a listview in the same page. Listview shows one record. this happens when i select a row in the grid.
I have successfully managed to get my listview to appear inside a jquery dialog. the problem is that i cant do the edits and insert when inside the dialog box. What happens is that after i press update , after the postback the dialog box has a blank form.
After researching (stackoverflow question) i have found that the problem MAYBE is that the dialog option creates a new div inside my div (by examing the resulting page). This breaks the association of the child elements of the listview and they appear blank....
the solution proposed there has to do with one field. How can i apply the logic to the whole list view?
I have connected GridView with a datasource. It works fine but it is displayed just at form load. I want to show it when user clicks the button. How to make it so?
Thanks
Try setting the Visible attribute of the GridView to false. In the Click handler of the button, set the Visible attribute of the GridView to true. Rebind and use an update panel if necessary.
If you post some source code, we can give you a working example.
In a ASP.NET application I have a paging RadGrid which shows up textbox in each row. Outside the grid, there is an OK button to save the content of all the textbox. If user changes text in any one or more of the textbox and without clicking on the "OK" button, tries to move to a different page number (of the grid by clicking on the page number), he should be prompted for confirmation of save or cancel the changes.
I am guessing that one can write a Javascript function which would look for any form input control (textbox in my case) and detect changes and If there are changes, would prompt the user. However, I am not sure where I can call this function from? Any suggestion on this or a better way to achieve this would be appreciated.
I am using RadGrid but I guess this should be applicable to GridView as well.
I am not sure if this will help exactly but it might at least give you an idea:http://www.codeproject.com/KB/ajax/ajaxdirtypanelextender.aspx
