This is the code which I am using for altering the number of columns in a table in the DB. so with this code i am able to add new coulmns dynamically. Now my major requirement in this is to obtain the headercount from the user( say "telephone number" and "language") and based on it generate the columns dynamically in the table in the DB.
I wanted to know if it is possible to dynamically add columns to a table in the Database?I know how to create a table dynamically in the DB the code for it is given below, howver I do not know, how do I add columns to it dynamically.
Dim NewTable As String = "CREATE TABLE Dynamic " +
" (" +
" job_id smallint" +
" IDENTITY(1,1)" +[CODE].....
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.

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.

how to write complete code for above query
I have been searching for some time on the net for guidance on this question. Finally thought I will ask here...
I have a gridview that needs to be generated from code behind. There is a column with a name field and the remaining columns give the different user-ids linked to that id. Like this:
-- NAME, ID1, ID2, ID3......
The Name column will be populated from a table that has the Name as well as number of ID's associated with that name. eg [Name1][3]

I have a datasource, which includes many columns, idealy, I need use a gridview to show:
1) first 3 columns: template fields, these fields depends on values in some columns of datasource. I use template fields, hard coded. works fine.
2) the other columns. This is I do not know how to do it. In the data source, there are about 10-20 columns data, each time, the # of columns of the data varies. idealy, I need show each of them as a seperated column in gridview. The entire data source may have 30 columns, but some of them are used in 1), and I only want show these 10-20 columns in gridview. Some columns in data source, I may not use them at all. is there a way to do this? or have to seperate them as a detail view style UI?
I'm trying to view a list of uses that have the execute ability on a function, but I cannot find a method to do so.

View 6 RepliesI haven't had any luck finding the answer yet. My problem is that I want to be able to update the dataformatstring on a gridview column at runtime. For example, I switch from displaying # of units to cost of said units... and I want to change the format of the column to {0:c}. It seems like it should be a simple task.
View 2 RepliesI had just started with Visual Studio 2008 + VB.net. I've now designed my tables, and basic gridview functions properly.Now I'm faced with the problem of having to calculate a value based on 2 - 3 columns/data in the gridview, display the result in an existing column in the same gridview, and saving the calculated value in the datasource.I had initially created the "Total" column as a textbox displaying a manually calculated amount that is saved in the datasource. Now, I want to change the field to auto-calculate based on 2 other columns.
View 4 RepliesI have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?
I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.
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 want to add this two columns dynamically to gridvew in codebehind.
I am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?
