Manipulate A Gridview In Asp.net When Columns In Gridview Are Generated During Runtime
Sep 24, 2009
In my application,i have a gridview in which columns are created at runtime.Actually these columns are created when i am entering data in a database table.[code]where Column1,Column2,column3 may vary during runtime.i need to enter values to these columns during runtime.But i cant bind these columns because these are created during runtime.The first column "Description" will not change.It will remain constant.For each description, there will be values for each column.At last these data will be saved to the database.How to add columns in the gridview during runtime?
I am trying to format the width of my gridview columns dynamically for easy of use in editing and updating. Is it possible to have multiple column widths defined? Here is the code I am using to create the gridview...
protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack)
I have created a Stored Procedure in SQL which produces a pivot table. I've successfully created a GridView in ASP.NET to display this data.
However, some of my column headings are dynamically generated from the data (AutoGenerateColumns=True), and those column headings are just dates, so they will look different almost every time the table is generated.
This all works fine, except that the date format of the column headings is wrong. I know I could change the way SQL produces the dates in its output, but I don't want to do it that way. I want to control it from the web page.
I didn't think this would be difficult - I thought I could just do something along the lines of finding the cells in the header row and changing the datastringformat. The problem is that whether I put my code in the GridView's DataBound or RowDataBound event, the cells in the header row seem to be empty, so I can't reformat them. It's as if the headers get populate some time AFTER the DataBound event, but I don't know when or how to trap it.
an aspx page where a user can upload a file to the webserver, and then then webserver can bind the csv file to a grid view, and allow the user to mark what fields are what.here's my code to bind the csv file:
uploadFile = CType(Session.Item("uploadFile"), String) Dim sConnectionString As String = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" _ & MapPath("~/upload/data/") & ";
I've got a gridview with two buttons in it. I would like to determine which button has been pressed in my VB code. Is this possible? I've been able to determine which row number has been pressed, or what the value of the first element in the row is, but columns don't seem as easy.
I want to bind Grdiview with DB.I have a table Products with three columns.Suppose I add three columns at design time in gridview, If I run my following code First Three columns are blank & next three columns are bind with data.

This is a follow up to my previous question: Filter DirectoryInfo files by date in asp.net
I have a gridview that is populating data from DirectoryInfo. However, I only want to display certain columns, and customize the column names and the hyperlink value in the row.
My code is:
Dim files As FileInfo() = New DirectoryInfo(strDirectoryPath).GetFiles().Where(Function(x) x.LastWriteTime >= (dtStartDate) AndAlso x.LastWriteTime <= (dtEndDate)).ToArray()
[Code]....
How can I loop through the columns, to display only "name", "extension" and LastWriteTime?
Well i have a list of objects List<UserDC> now i would want to display this in some kind of grid so i tryed the GridView[code]...

I am trying to program my page in vb.net and asp.net so that when a user clicks on a column heading of a gridview, the data is sorted either in ascending or descending order. note that my data is coming from an SQL Server Express database. So far, I have done it so that the gridview can be sorted:
I have a variable defined as follows:Dim iRows As List(Of String())I've also been converting that to a list of lists just to make it easier to work with.Dim iRows As List(Of IList(Of String))I would like to bind that list to a GridView using the contents of the nested array/list to dynamically define the columns. I don't know ahead of time how many columns there will be, but I do know that they are all the same throughout the list.

I am looking to be able to add items to a combox in a gridview at runtime. The only code that I have found is for an editable datagrid combobox not one that items can be added on runtime. Is anyone now of a free datagridview control that does this?

I re-wrote this to make it more readable. If you want to skip right to the chase, look at the ALL CAPS comments in the code blocks. All necessary code has been included for debugging. I've searched multiple forums (including ASP.NET), and the MSDN library and cannot fix this >.<
How to show pop up menu from database in gridview on each gridview row items ?Example of this is : http:[url].....Move your cursor to Departure time and arrival time...a want this type of popup in gridview items....which fetch entries from database..
Please can you translate the above line of C# into VB.NET?At runtime, I'm trying to update an existing GridView column, as opposed to adding new columns, just before a DataBind()
I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:
Select C.Name, From Clients as C
[code].....
How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).
I am able to export a gridview to excel, my problem is that I cannot figure out how to remove the formatting from coming over from the girdview. Here is the code I am using to export the gridview: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I have a modal popup that contains a gridview. On the click of a button inside of a grid i reload the gridview with the data that depends on the id of the row clicked in the gridview. I would have like to reload the gridview onclientclick but I couldn't find a way to do that. Is it possible to reload a gridview client-side without the user even knowing the page partially loaded?
