Data Controls :: Adding Dynamically Multiple Rows To GridView
Dec 4, 2012
I follow this code [URL] it works. But the example is show only for 1 row.. come to my case when user want 12 rows for the first time gridview row load. I manage to add it by using for loop. but i stuck at the how to set previous data when user add new row to 13th row. The gridview seems like refresh and the entered data is gone!
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.
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.Count - 1 Dim TableCell As New TableHeaderCell() TableCell.Text = header.Cells(i).Text row.Cells.Add(TableCell) Next Dim t As Table = TryCast(grid.Controls(0), Table) If t IsNot Nothing Then For i As Integer = 0 To Gridview1.Rows.Count - 1 If IsWhole(i / 5) Then t.Rows.AddAt(i, row) End If Next End If End If End Sub
I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.
Here I am binding a gridview. I dont know exactly how many rows it will exists. there may be from 1 to n rows possible there are 4 columns.
Now what I want , i.e. after gridciew binds records, suppose there are 4 rows are bounded to gridview, I want to send all rows data through mail, but in my html format there are fixed rows. I want to add rows according to throws which gridview having.
suppose gridview binds 3 rows the mail format should be like this
Date From Date To Place Days 12/12/2010 14/12/2010 Mumbai 2 12/12/2010 16/12/2010 Goa 4 12/12/2010 20/12/2010 Pune 8
1. first tell me how to get this data from gridview in variables so that i can put them in my mail format
2. this condition if grid bind only three records cos I have fiexd rows in my html format.. but if grid is haing 5 records then how will I add rows to table in my mail html format
I am working with Gridview control and I am also adding radio button to each row in ASP .NET. Here is something that I would like to accomplish but I am not sure how this should done. The problem is that I have add a muliple datarow insie of the each gridview. Something like below.
So, some cases I have add a row with two rows like the example. And, the ID eventurally will be radio button where user can click.
I have been tinkering with a adding row to gridview code from [URL] I have been able to adapt it to my needs but I would like to have the user edit the select statement that shows the initial gridview form.
I need to produce a from where I can add multiple parts. Each time a user enters a part number, the description should be populated. The user can then click add and this part and description will be shown below. They have the option to add as many parts as they require. Once all parts are added the user fills in some general info eg description and then once a submit button is clicked all part info will be inserted into a table and general info will be inserted into another table with one unique ID.
I am creating a web application that displays URL to users in a GridView. The application has a code behind that will be doing the processing before it can return me a URL. This is done in a loop. So it looks something like :
What I wanted is to make the Gridview always update the rows everytime an item in the loop is done instead of waiting for the loop to finish.
For now, the application will only display the whole table until the code/loop finishes. I'm very much aware that this will happen because the web page is static in the first place. Does anybody know how to do this?
I have tried of using iframes(I thought of reloading the frame so the whole page wont reload again and a new GridView table would appear because of the code in Page_Load event because I tried placing the data in a separate static class and the GridView.aspx page will just retrieve the values upon every reload)
i have read and used this script.Adding Dynamic Rows in ASP.Net GridView Control with TextBoxes..it is very usful to me but i want to fetch data from sqll database and fill the newest row with it. the past row data hav to be remain same. becoz of the same name of textbox it happens. whenever i try to fetch data from database and fill textbox all rows get updated with the same data.
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've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls, etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)
i'm using the code below to select multiple rows in a gridview using a checkbox, how do I modify the code in a "select all" button click event to select all the rows by checking the checkboxes in all the rows? How do I also clear all the checkboxes using sa "Clear" button click event?
