Adding Dynamic Rows in ASP.NET GridView Control with TextBoxes and with Delete functionality

I decided to write this article because this has been asked so many times before at the forums(http://forums.asp.net) . Basically, this example shows on how to generate a Row in GridView with TextBoxes when clicking a Button that is residing inside a GridView Footer.

This article describes on how to add rows in GridView without using a database. Basically the GridView will be populated with data based on the values entered in the TextBox on Button Click and retain the GridView data on post back.

 Hi All,Pardon me if this seems redundant. I have searched the archives and found many references to this type of error. Most (all?) boil down to a mismatch between the token for the databound field and the sql parameter. I have stared at this code for a long time and can see nothing wrong with it. In fact, it is so simple that I started over from scratch using only the designer (ie I wrote no code), so I don't see how it possible to have a name mismatch. I would very much appreciate any help figuring out what is the problem here. Thank you very much in advance.-Roger   Server Error in '/ssp/inet220a06' Application.

Hi,I'm having difficulty understanding what dynamic data actually is.There is an option to specifically create a dynamic data project, but I don't understand the difference between this, and just adding some kind of data control, like a gridview or detailsview for example.If someone can help me understand this better I'd really appreciate it.

My requirement is something like this:

In a Task Approval form, I want to have a view which shows all the rows in a particular SQL table (in a infopath repeating table?). Along with each row, there should also be a button, on clicking which the row should disappear from the infopath view table. Do you think InfoPath can handle all this? :) 

To summarize:

1. How do I add rows to a table dynamically?

2. Per row, how do I create a button dynamically?

3. How do I remove the row from the view when the button is clicked?

Hello all!

I'm having difficulty adding a repeating header row, every x rows, to a gridview.  I'm able to add the header only once with the below code.  For some reason it will only add it during the last iteration through the for/next statement.  I tried manually adding three separate .addat statements to different rows and it only executed the last .addat statement.  I couldn't find any information on why it's only working the one time and I hope someone has a fix or better solution.

Thanks in advance!

Code snippet (Note the IsWhole() function verifies that the rownumber divided into a whole number):

Protected Sub Gridview1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles Gridview.DataBound

        Dim grid As GridView = TryCast(sender, GridView)

        If grid IsNot Nothing Then

            Dim row As New GridViewRow(0, -1, DataControlRowType.Header, DataControlRowState.Normal)
            Dim header As GridViewRow = POSTURE_RESULT.HeaderRow
            For i As Integer = 0 To POSTURE_RESULT.Columns.C

Im learning and experimenting with jQuery and ASP.NET. Below is a simple solution I created to highlight rows in a gridview by clicking on a checkbox next to the row.

how we can access a particular control which resides inside a GridView control. In this article I will show you how you can access different controls inside a GridView control. We will see how we can access a TextBox control, a DropDownList control and a ListBox control.
