I'm working on setting up a Gridview that dynamically creates new "columns" after a set amount of rows. To do this, I bind a datasource to the Gridview and then add new cells and shift the other items into those cells. I seem to be having an error with the link buttons that I move around. All of the items get put in there correct location, but for some reason, when I click a link button that has been added to a new cell, the sender's text is the LinkButton in the original cell's text. Does anyone know why this would be happening? Is the gridview not meant to be manipulated after it has been data bound? This is the code that I use to update the gridview.

I created a gridview that is made up of 4 gridviews and using a stored procedure to populate it. I create columns at runtime because the number of columns changes all the time.To make the grids editable I am adding template fields at runtime as I create the columns, this is to ensure that a user is able to edit the cells and some foot values update. Reason why I have four grids is to freeze rows and columns like in excel using javascript. The problem is that performance is very bad especially in IE, the grids take a long time to load. I am not sure if this is caused by the data load or the creation of text boxes. see some of the code below for my _aspx page:
[Code]....
Gridview-
Id Name Initial
1 abc A
2 def B
3 ghi C
After transposing,I want it to be like this-
Id 1 2 3
Name abc def ghi
Initial A B C
how to transpose in c# with code and if it is made as a function then how can I call it?I'm new to c#.
I have a IEnumerable result, passed to my view. Now, I want to display five elements for my Model in one row and next five in second row. How can I do that?
View 1 RepliesI put in my page 1 table like grid with this style:
header of columns are select from table persons(so number of them are dynamic)
header of each row are select from table goods(so number of them are dynamic)
in table , in each cell,show the price & the date ,that this person,buy this goods
for example,in may 2008 ,Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
so this table has 2 column & 1 row
in may 2009,
Jack&sara buy pencil.so in front of pencil&buttom of jack we write his price and in front of pencil&buttom of sara we write her price.
and jhon buy pen & suzzan buy book so this table has 4 column & 3 row
Price Date
Price Date
Price Date
Price Date
Pencil
Pen
book

I know that there can be 24 relevant periods for each user. There may or may not be all 24 present for each user.
Now all that 24 periods I have in an array in C#. I know what these periods will be. They change so I cannot hardcode it. It has to be dynamic.
I want to create 24 columns of that rows for relevant periods and display TotalCount in that and get all other data accordingly in c#.
I want to put an input table on a web page using ASP.NET. The input table has 3 columns: date, quantity, and price. The number of rows is variable, depending on user input. The code behind will read the data and perform the necessary calculations. The data will not go into a database. It would be nice to have some client-side or server-side validation for the data, such as required fields and range checking.
Which control(s) in Visual Studio 2008 will perform what I want to do?
Iam working on an asp.net application.Recently client come with new requirement. Need a control which is similar to table or like gridview with rows and columns.It should allow user to enter data in the cells. And when the user press tab it should go to next cell and finally if we press enter key, it should validate the data entered in the current row and if data is correct it should create a new empty next row(like entering data manually in an sqlserver table). How can i implement this functionality? Can i use gridview / javascript to implement this functionality.
View 1 RepliesI have a couple of things that are not working with my Gridview:
1) I've managed to display 3 columns in one column (see code above) but the data is separated by commas, how can I display each data item in separate rows.
2) How can I make the data unique, as I have added the distinct command which I configured in my SQL data source
3) I need the rows to not display nulls, but at the moment it isn't displaying the row if one of the columns is null?

I have gridview which auto generate column is false, and I add some template columns, databind with a class ClassA . it works fine. now, I need add some columns to this gridview. the problem is: I do not know the # of columns that will be added (it is dynamic), and the data with these columns is in ClassA, but it is a array (or list). so, there is no public property for these data, only the array.
now, what I did is: I dynamically add template column to the gridview (column header ...), so, it shows the correct columns in the gridview, but how can I bind the data? I found some example, i.e.
[URL]
but it is for aleady know the data field (which is a public property in the class). all I have is just a array, and I need bind them to the newly created columns in sequence.
<?xml version="1.0" encoding="utf-8" ?>
<mappings root="sound" child="item" delimiter=",">

I am looking to 'hypothetically' post nine rows of data with column headers for 15 different columns. That would be too many textboxes. All the data is directly calculated in VB.net. I want to insert some sort of spreadsheet-type deal with the tool "Table" or something I heard about "Gridview?".

View 2 RepliesI have a CSV file (with semicolon field separator) of 150MB (about 2 milion rows and 35 columns).
Now I want to loop through the CSV per row and get each row column.
My requirement is when user clicks Add button, the textbox value must be added to listbox. The following code works well

But i don't want the user to add same text multiple times. The listbox items(Text) must be unique.
