Forms Data Controls :: Redirect Selected Row To Another Page?
Jun 13, 2010
I have a web app that works with an object-relational database. Displaying data in a gridview is one thing, but when it comes to updating that data that is quite difficult with nested tables, user-defined objects, etc (I've had errors such as"Reference to a NULL table value", and a couple of things). My fix to this was to update the data on another page. '(This method involved using textboxes and a button, no detailsview or gridview).
So I'd like to know how do I select a row of a gridview in page 1 and that row displayed on page 2 for editing? I followed the steps here: http://forums.asp.net/p/1122208/1755008.aspx#1755008 and got the error "Object reference not set to an instance of an object."
This task seems pretty simple, but I don't know how to do it.
(In case you're wondering why not just use the method I had, it is because I had a text box to enter the PK of that row. I was told that for the web app to be more "user-friendly" the user should not have to enter the PK, but instead click on that row from the gridview and be directed to a page with that row already selected. Then I'll use that method)
I have two gridviews on same page - If a record is selected in Gridview1, I need to unselect a record (if one is selected) in Gridview2 - and vice-versa.
I'm new to ASP.net (and coding in general) and I was very impressed about how easy is to learn enough to create something useful :)
Unfortunately, now I'm stuck on a problem involving gridview sorting and paging: I created a master gridview bound to an sqldatasource, I enabled sorting and paging and then I linked it to a detailsview to enable editing and inserting.
In addition, I set up two other gridviews whose datasources depend on the master gridview.
When a user selects a row and modifies it in the detailsview, the sort takes place and the row is often moved to another page. This can be a little confusing, especially because there are other controls relying on the selected row of the master gridview.
There's a way to find and select the page of the selected row after gridview's databind and sort take place? I tried creating a dataview to search the index of the selected datakey in the databound event of my gridview, but it doesn't work, because it seems that the rows aren't sorted yet. Maybe I should choose another event?
I am using some code similar to the code below to open a word document on my ASP.net app. Once the file has been downloaded and opened I then want to either redirect to another page or refresh the screen but nothing works after response.end and if i add it before response.end the browser never downloads the file?
