Asp.net - MasterPage Data Bind To GridView?

Jun 14, 2012

I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.

I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

EXCEPTION
Object reference not set to an instance of an object.
MASTERPAGE CODE BEHIND
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

Data Bind A Drop Down List In A Gridview From A Database Table Using VB?

Dec 4, 2009

So in this gridview, there is a column for status and I want to have a drop down list with Pass, Pending, Fail appear when the edit button is clicked. These values are already in a table, so I need to somehow bind from this table to each ddl for every row.Here is the column from the gridview.

Refreshing Data Using AJAX In ASP Masterpage?

Jan 16, 2012

I have some processes that run as a background job, allowing a user to continue to use a page, when the jobs are finished (which can take a few minutes) i want to display a message to the user, the best place to display this would be the masterpage AFAIK (incase they move from page to page on the site) so i have defined a div in the masterpage file.

I am trying to find the best method for displaying the data, at the moment i have a method in the masterpage vb file which polls a database to see if the job(which involves complex logic and some db access) has completed, if it has, it shows a message in the div e.g. "Job 13132 has completed" - which works fine.

The problem is this is not dynamic, and i have to refresh the page to call the function that checks if the processes have finished, how can i use AJAX to deliver this content automatically every 5 seconds?

I have tried using an asp timer with a 5 second tick time but the entire page refreshes on the timer click event every 5 seconds.Protected Sub Timer1_Tick(Byval sender as Object, Byval e As EventArgs)

[Code]...

Is there a way to only refresh the div with the updated message, without a full refresh happening using this code? Or if this is not possible, is there any way to replicate the above function using jQuery and still be able to update the DIV text only if a job as finished?

Asp.net - Bind Dictionary To GridView?

Apr 30, 2012

Algorithm to count the time that occured on the same period, how to bind the dictionary to the GridView? Pls take a look to the answer.

I tried to add a GridView and then on the code-behind: GV.DataSource = timeRangeCounts and bind it, but in return:

The data source for GridView with id 'GV' did not have any properties or attributes from which to generate columns. Ensure that your data source has content.

take a look at the code below:

Asp.net - Bind A GridView To A Custom Object?

Apr 1, 2011

If I have the following ASP.NET code (it's not complete - obviously there's a lot missing, but none of it matters):

<asp:GridView>
<Columns>
<asp:TemplateField>
<ItemTemplate>

[code]....

How can I bind the GridView so that one row is equivalent to one item in my MyListOfObjects list, and so that the data will populate and persist across page loads or postbacks? I've never done custom databinding like this before, so a full explanation would be very helpful. All the tutorials I've come across so far only talk about using GridViews directly with Database query results, and that's not what I need.

Bind Multiple Sources Of Data?

Jun 13, 2012

It's been a long while since I've done any VB.Net coding and need to bind some data to a form. I have multiple tables that share some common primary/foreign keys and need to easily be able to update them.

For example, I have a table with an ObjectID, TypeID, AreaID, and several other fields. When doing my layout, I need the TypeID (found only in the main table) to be a distinct value in a comboBox, and in the ComboBox which contains the Area to be the Area Description (from the main table tied to the Area table via the Area ID).
