I have a vb.net page that has a editable detailsview. When a user wants to erase the data for a field, they highlight the data, and delete/backspace over it, and click update. However, the original data is still saved. If they are replacing the current data with new data, that works fine and updates/saves correctly. This problem only happens when the current data needs to be removed.
I have a webpage with a select object and a GridView object. For testing my problem i've created asp button and html button.On pageLoad the GV is empty and select is being filled with names. (GV is not appearing)After choosing a name from the select options, the user should click a button and then the GV need to be filled with relevant info.I am having 2 "related" problems:
1. When clicking on the asp button and getting into the click function on the aspx.cs file, i can't find the select object and retrieve the selected option. How can i get this?
I am using Visual studio 2010 express and I have a details view databinded to an sql database table. When I use the Insert option on the view it causes an error due to it trying to insert a null into the primary key field. If the Insert function does not create a new primary key entry how is it created?
The page you see below displays one entry in my database and should allow you to click the Validate button if the validation_code for that entry in my database does not already have data bound to it.Once data is bound to that particular database entries validation_code field the Validation button should no longer be displayed.The problem is that in my database some entries have the validation_code field filled in and some are null (empty) but the script is seeing every entry in the database as if it was filled in. So, no matter what is in the database for a particular entry, if any other entry in my database is filled in, the Validation button is disabled. I only want it disabled if that particular entry has data in the validation_code.
I'm thinking of using a modal pop up control that would have a details view in it. I currently have a details view that uses CSS Friendly control adapters with the CssSelectorClass attribute. Can I use the CSS friendly CssSelectorClass property with a details view in the modal pop up and style it as I'm currently doing with my Details View?
This code is included in a usercontrol, the usercontrol is used in a ASPX page and this ASPX-page uses a MasterPage. I've noticed that if I'm using
<%= modalInform.ClientID %>
I'm getting a different value then defined in my HTML-source (propably because of the MasterPage?).
I have a simple page containing a GridView control that generates thead and tbody tags after rendering. In my jQuery script, I have a line that reads this way:
When the page loads for the first time, this script returns an objects and works well. But when I click a button and cause a postback, it returns null. By the way, the button changes the number of the rows returned from the data source (based on the value of a textbox) and updates the grid.
I have on a page a gridview that can be filtered with one text box. I set up the gridview to show select and wanted to then connect a details view so that when you selected a row the entire details would show up. When I run it I get this error. Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys.

I'm trying to get a record to show up in a details view as part of a Master Details. I was able to get this to work by setting the visibility to true for the Details View in the Page Load event. I now want the details view to show up when the Select button is clicked in the GridView's template field using the onClick event for the button. I don't seem to be assigning the correct properties to get this to work though. what property I should use with this? I know I have to get it from the GridView and assign it to the details but haven't gotten it to work. this is the GridView:
On the HTML code is rendered only the first view or the view that is activated on page load.
I am tryting to reach controls in the gridview rows by RowCommand event. I can take values of controls which are binded to gridview source successfully . But for all other controls which is not binded to gridview returns NULL value. All controls run at server. Why is that?
I am using VS 2008 SP1. My also have included CSS Friendly adapter [URL] in my project ( I mentioned this because my GridView Empty data template is not showing when using GridView's CCS Friendly adapter). I have a GridView and a DetailsView. When a record in GridView is selected its details information is shown in the Details View. Type of Data source I am using is ObjectDataSource. My Insert and Update methods works perfectly. It is only the Delete method that is passing null values to the underlying object delete method. My source codes for both the UI, BLL, DAL is shown below
