Forms Data Controls :: Exception Handling With Declarative GridView?
Jan 17, 2011I'm using Visual Web Developer 2010 Express with C# 2008 and .NET v4.0 to create a website which will have a database application. The database is SQL Server 2008.
I would have searched this forum for similar questions but I can't find a 'Search this forum' option! So I apologise if someone has already answered this.
I've successfully displayed rows from my database by dragging and dropping a GridView and an SQLDataSource control onto my page, and by using the Connection Wizard to set them up. But when I go live with my new pages, I will have to put my database in a different folder, and until I edit the web.config connection string to point at it I expect to get an exception.
I understand that when you try and open a database connection, this is the perfect place to use try...catch exception handling. But all the examples I can find put the try-catch code on the Button_Click event! Where should I put it? I can' t find anywhere where my controls actually attempt to open the database!
I know I could rip out what I've done and write all the code to connect to the database myself, but as I've finally got everything to work I would prefer to make the change as small as possible. So, what is the minimum change I have to make to add exception handling to my datasource/ gridview?
Forms Data Controls :: Handling / Preventing GridView Refresh On Deleting Row?
Aug 4, 2010Before I begin, I would like to acknowledge that I might be using incorrect terms below due to my lack of experience.
I have a GridView bound to an ArrayList of Custom Objects. I have a button as part of each row, which when clicked, I delete the row from the Arraylist, and re DataBind() the GridView. While this deletes the Row, it causes the Page to be refreshed that takes the User back to the top of the Page.
E.g. If the User clicks on the button of a row at the bottom of the Page, after the deletion, the Page gets refreshed and the User is now taken to the top of the Page.
This is irritating especially in long lists i.e. GridView with many rows. (I don't want to use paging here.) Is there any way to avoid this, or mitigate this problem.

Forms Data Controls :: Handling A Gridview With Multiple Checkboxes And Radiobuttons Using Javascript
Feb 1, 2011I'm fairly new working with Javascript. I'm working on an issue where I have a GridView with multiple Checkboxes and Radiobuttons. A user can check multiple checkboxes and if a radiobutton is selected, a checkbox has to be selected. This scenario is working fine, presently with existing asp.net code. But, I want to automate it using Javascript, so that I could avoid a postback.
View 4 RepliesForms Data Controls :: Handling Events From A User Control Inside A GridView?
Jun 4, 2010I have a user control called ucTriStateButton. It raises an event when it is clicked, called TriStateButtonClicked. If I put this user control on a page, it works fine. Here is the declaration on the .aspx page:
[Code]....
When the button is clicked the method tsbTest_TriStateButtonClicked executes correctly.
The problem is when I put the user control in template field of a GridView.
[Code]....
There is no way to hook the event handler to the control in Page_Load because I cannot get a reference to tsbMorning. So I did it in the RowDataBound event handler of the GridView, where I also do a bunch of other row-specific stuff. Although this builds and runs, the event is never actually subscribed to and so never gets fired.
So the question is - how can I handle an event from many instances of the same user control within a GridView? I am calling the same bit of code regardless of which user control is actually clicked. I only need to know that one was clicked.

Forms Data Controls :: Manually Handling Sorting In Gridview Populated By File System?
Jun 21, 2010not quite sure where I'm going wrong here. I'm trying to manually handle sorting in a Gridview that is populated with the following data source:

[Code]....
[Code]....
At the moment, nothing is happening when I click on the column headings. I ran it in debugging mode in Visual Studio and put a breakpoint on the Sorting event handler. I noticed that the variable dtSortTable is empty even after the TryCast(VacanciesGV.DataSource, DataTable). If I hover over this statement in debugging, it shows the data from the file system, so it does appear to be reading it.

Forms Data Controls :: Adding Rows To GridView During Runtime?
Dec 10, 2010I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
[Code]....
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?

View 4 RepliesData Controls :: Making GridView Open In New Page Update Changes Made In TreeView Gridview At Runtime
Mar 26, 2016Query 1 - Grid View: - I have an excel sheet which I import into gridview at runtime. For excel sheet import, I have a fileupload dialog box and an asp.net button control which when clicked imports the sheet contents into a gridview. The problem is I have my fileupload box and button control in a page called Default.aspx and I need the gridview get displayed maximized in a new page called Default2.aspx.
Also, I need to specify the row number of the field titles from the excel sheet dynamically at runtime so that the gridview appends any new field/column from that row on. The excel sheets I use contain complex formatting. Is there anyway to display the excelsheet contents as they have been defined and formatted?
Query 2 - Sessions: - I add nodes to my treeview dynamically at runtime. Since HTTP is a stateless protocol, the changes which I do remain only for that session. How do I append the changes I do to the treeview simultaneously in the code?
- I have appended 2 extra columns into the excel sheet generated gridview which take input through dropdownlistbox control at runtime. How do I update and retain those changes in the gridview?
