Forms Data Controls :: Adding Dynamic Columns In An Existing Gridview?
Mar 2, 2011
I have a Gridview on my aspx page. On my page_load event I check for a record in the database, if the record exists for that row in the gridview I would like to add a new column in the same gridview and add a button control to it. This adding of new column in the Gridview should happen in the codebehind (c#). see the code I wrote for this, but when I run it, it does not create any column on the gridview page.
[Code]....

I have a gridview that contains template fields with textboxes that is used to look up inventory items. The page loads using an arraylist to display a gridview control with a predetermined number of rows. There is also drop down control that allows the user to add additional rows to the gridview if needed.
Currently when a user has already entered some data if you use the drop down to add more empty rows all the original entrys are removed. I want to save the original data and then add empty rows at the end.
>>
Private Sub LoadDataGrid(ByVal numberOfRows As Integer)
Dim Counter As Integer
Dim GridList As New ArrayList
For Counter = 0 To numberOfRows
GridList.Add(New LibVB.Form2VB(Counter))
Next
gvEnterParts.DataSource = GridList
gvEnterParts.DataBind()
End Sub

I have a Gridview with autogeneratecolumn = yes since the datasource always returns different columns of data.
However, except from left most column, all columns to the right should be formated to #,###.#
How could I format these columns to the right dynamically ?

I'm just wondering if anyone can assist me with this gridview problem
I have this Sql statement that outputs a gridview like this
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
* These columns are placeholders
I want to include a footer total that looks like
Job Location Activity 1 Activity 2 Activity 3
Job1 Location1 0 0 1
Job2 Location2 1 0 1
Job3 Location3 0 1 0
Final Total 4
Im not binding the database to the gridview via design view I'm binding it programatically in the default.aspx.cs file
So far the only tutorials I've encountered are ones the have the database bound through design view and gridviews with only one column that can be added. In my particular example I have multiple columns that need to be added and I have already bound the data to the gridview.

i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview
[Code]....
and here is my gridview:

I have a gridview, where I set the columns based on the columns in a datatable. I have a class that implements ITemplate, and creates a textbox template field. Everything works good, I can display my grid with the correct columns and headers. The probem comes up when I click a Save button, to save the user input. Of course the page postbacks, and I re-create the columns on PageInit. However, all the data the user entered is gone.

My datasource is an ado data table that I have convert to a new data table so that each row in the original table is now a column with 1 row in my new table. I then bind the new datatable and create dynamic template fields with a text box where I bind the values. My problem is, when I try and retrieve the values changed by the user in the rowcommand event, the template columns no longer exists.
Does anyone know how i can retrieve these values? I've read over and over that you have to rebind the grid on each postback when you use dynamic templates, but I'm not sure how to do that and retrieve the values entered in the text boxes on the client side.

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:

I have started creating a DAL and have successfully bound my adaptor and the query within the adaptor to a gridview.
In lots of the intranet type apps I code in regular ASP for myself I often have a few columns with little icons in that do various things for that rows identity, such as drill down to more details, overlay a graph, text the person via an ajax call, send em an email via ajax and so on.
I think Ive got the hang of styling elements of each row depending on the data but Im completely at a loss as how to add a column which would have an icon whos url link properties would be dependant on the data.
EG
ROW1 | Name | Email Address | ICONFOR EMAIL(with a querystring id matching the row id) | ICON FOR MORE DETAILS (with a querystring id matching the row id)
I realise I am probably looking at this the wrong way but its difficult when you are almost on autopilot doing these things in classic ASP.

I have the following code:
[Code]....
With this code behind:
[Code]....
Initially, I wrote the GetTeamMember() method to display the FullName in the ItemTemplate.
Then as I wrote the EditTemplate, I needed to populate a DropDownList with a list of names (first and last). It was fairly easy using the LinqDataSource, however it currently only shows the LastName. I could write another method GetTeamMembers() to populate the ddlTeamMember with the data I want, but I thought maybe there's a better "LINQ" way.
So I'm looking for a better way to get FullName (i.e. Firstname + " " + LastName) into both lblTeamMember and ddlTeamMember.
Options I thought of are:
I could write a method GetTeamMembers() I write a StoredProc that returns the extra column Better way?

I 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
