Forms Data Controls :: OnRowDataBound Or Custom Protected Method GridView Databind?
Jan 6, 2010
In a GridView control ASP.NET
OnRowDataBound="gvTest_OnRowDataBound" followed by
protected void gvTest_OnRowDataBound(....){}
OR
Text='<%# BindMyData(DataBinder.Eval(Container,"DataItem.Price"), DataBinder.Eval(Container,"DataItem.CurrencyID")) %>'
followed by
protected string BindMyData(object price, object currencyID)
{...}
Which one is best in terms of performance and coding best practice?

All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.

I'm trying to databind my GridView to a custom datasource where one of it's members/fields is a collection.
Custom object Entry
public List<EntryHour> Hours { get; set; }
In practical terms, one row consists of some normal text fields which is easy to handle. However, the Hours field is the nut to crack.
How do I, in the GridView markup bind my textfields in question to the Hours field (which consists of 7 items allways)?

I'm using a standard GridView control inside of a web form. The web form uses a master page. The application is running within sharepoint (wss 3.0) environment. When i attach both the OnRowCommand and OnRowDatabound events to the gridview as shown in the markup below, only the OnRowDataBound event fires. The OnRowCommand never gets hit. When i press a button on a row, it posts back but never hits the onRowCommand event and simply falls through and repaints the page . However if i remove the OnRowDataBound event, the OnRowCommand event starts to fires correctly. I've tried a number of things...1. Hooking up the events in code instead of markup. (inside of PageLoad or PageInit)2. Changing the order in which the events are attached.

I'm binding an object to a gridview. The object (LeClient) consists of several variables, two of which are related to its phone number. One variable contains a string of digits (LePhone) and the other contains an int that represents the country code (LeCountryCode). I have an extension method for strings that works to format the string LePhone and that I'd like to pass it LeCountryCode as the parameter.
So far, on RowDataBound I have an event handler with the following line:
e.Row.Cells[5].Text = (string)(e.Row.Cells[5].Text).ToPhoneFormat(1);
I'd like to replace the 1 with the corresponding country code that's stored in the object LeClient associated with the row. How does this work? I tried
.ToPhoneFormat(e.Row.DataItem("LeCountryCode"));

I've got a problem with my onrowdatabound function. The situation is like this:
protected
void gvSQL_RowDataBound(Object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
switch (Session["Filter"].ToString())
{
case "NonZero":
if (e.Row.Cells[9].Text == "0")
{
e.Row.Visible = false;
}
break;
}
}
}
At the end I need to kill the Session, so my plan is to detect if it reaches the last row. Then I can kill it. Does anyone know how to do this? Or is there someone that knows a better to fix this?

I'm working on a project where I have to create a page that displays the "health" of a system. I run a query and display the results in a gridview with a red or green icon next to it. This works fine when the page is first loaded. My problem is that I have a thread that runs a query every 30 minutes and rebinds the gridview but the gridview never refreshes even though the data has changed. How do I get the gridview to display the new results? The databound event never fires a second time even though I can clearly see that I have received new data. I assume I am missing something simple but I just don't know what. What am I doing wrong?

So I have a GridView and several events that can be triggered (such as filtering and inserting a new record) to manipulate the GridView. I want to make sure that I'm not calling DataBind on Page_Load, especially since I might have to call it again when certain events fire. Is there a way I can make it so I only have to call DataBind once on the GridView after Page_Load and anything else has fired? Like some event that will absolutely fire last where I can put my DataBind?
The reason I need to do this is because the DataSource for the GridView is set programmatically from a DataView when the page is loaded, so DataBind needs to run every time. Just, hopefully, not multiple times each time...

I have a gridview positioning issue that may have been answered elsewhere, but I couldn't seem to find a similar post...
I have a webforms app containing a paged gridview (e.g., 200 records - 50 rows and 4 pages).
When the user clicks on a button in a specific row, another web page is launched to process that button click. When the user closes that page to return to the main gridview, the databind event is rerun and the page redisplays the gridview starting at the top. However, I want to have the previous position maintained (like an html bookmark), so that the grid will automatically be scrolled to the the previously clicked gridview page and item.
Setting attributes such as "MaintainScrollPositionOnPostback" do nothing in this case.

I am have a page with a couple of dropdowns which serve as criteria for a select SPROC. Once a selection is made in a drop down a panel is shown which contains gridview whose rows have been returned by the select SPROC.If you close the panel and change the drop down selection and then redsplay your panel the data from your prior selection is still displayed in the gridview,
unless you page to the next group of records.

I have spent most of my time writing ASP.Net web pages, using VS 2005. I am now developing some client function for Windows, so I'm relatively less expert in VB.In my Windows program I have defined a DataGridView and linked this to a data table (within a tableadaptor). Now I want to populate it: on a web page's code-behind I would write Gridview.databind(). What is the equivalent with a DataGridView.

I've this table Table1(ID , LinkURL , LinkText )
I would like LinkText to display as a link. And when you click it takes the value from LinkURL and directs you to another page.
This is the code:

I have a drop down menu that is populated on page load. Below that, I have a gridview that has a select parameter based on that drop down menu's value. I can't get the gridview to populate with data based on the drop down. If I fill in the parameter with a constant, the data pulls fine, but when I switch the parameter to a form parameter, it won't pull.
Here is the relevant piece of the aspx page:

I am new to Entity Framework and working my way through it little by little. I think I have it figured out on how to get data into and out of 1 table at a time now the challenge is 2 tables into a gridview.
I have a user table that has a list of threads that a user can mark to track. Easy enough. Assign the userid number & threadid to a table with a push button while the user is logged in and viewing any of the posts that are on that thread. The new challange is to get only the posts that the user has marked to track. SQL easy. Entity not sure what to do.
If I make a view or stored procedure and add it to the database that would be an extra step. To join the 2 tables as in sql Select posts from posts where track.userid = @userid join track on post.userid=track.userid Seems Entity was made to avoid this type of thing. Than once the data is gathered I need to bind it to a gridview()
