Forms Data Controls :: Gridview Save Existing Data When Adding Rows Via Arraylist?
Jan 19, 2010
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'm lost, kind of a newbie to .net, have been working on this for 2 days! d.
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.
I want to bind gridview with datatable in this dt ihave 4 columns , dt
Id Name isdelete value 1 xyz true 2 uio false 3 bbb true 4 ccc false
this is gridview
[Code]....
but i want not bind those rows whose isdelete coumn value is false and i want to show 4 th column as textbox and user will enter some text or number and if he click save button outside of gridview one record shld save in database
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 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 :
[Code]....
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)
and I'm not sure how to implement AJAX/Javascript with this. Is Animation involved in this kind of situations?
I want to be able to select rows and save them for later display. I wish to store the data in a session object for viewing before i decide to save permanent in database.
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 have changed the look and feel of the grid by modifying the cols, rows in the gridview. I need to save this in the gridview viewsate, so that it load the modified look and feel next time it loads from the viewsate.
How can i save selected rows of a gridview (appearing inside javascript pop up page) into another gridiew (appearing inside "other" java script pop up page) on SAVE button click??
i hav a gridview ... now i need to add certain number of rows... say 5 rows .... which would b blank .. the rows consist of itemtemplate of textboxes.. here is the grid ...
[Code]....
now i am binding this gridview with certain data say :
[Code]....
now the problem is if the row contains 2 data originally ... then it alwz shows up with only two rows with binded data... but what i want is 2 (databinded rows ) + 5 (empty rows with textbox ) = 7 grid view rows .... now how to do it ... after i hav binded the textbox with data already....with some empty columns corresponding to the above code ?
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 have made a call logging application in which i have authorised a normal user to edit update and delete from the gridview.But i want to give the admin person rights to see all the complaints deleted updated edited..i have thought a lot but all in vain havent found.
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 came across the below article, I would like to know how to properly respond to the drop or stop event so that I can show the Save button only once someone changed the order. In other words, I would like the Save button hidden initially, only to make it visible once a drag and drop has occurred.
I have a piece of data that has a refererence number and then account name that looks like this in the database:
111111,Member Account~222222,Trial Account
I have the data spitting out just like that in a grid view, but I am wondering if there is some C# I can put in to where it adds a column when there is a comma and another column when there is a ~ in the data?
I have a GridView control of 5 columns out of which 2 are actually computed (there cell values comes from column 1, 2 and 3) columns. I want to save all the values of my gridview columns in a 5 dimension ArrayList and then lateron bind that ArrayList with a repeator control.
I've been trying to bound an arraylist to a grdview for display and managed to work out the following:
[Code]....
At the point where rows are added to dt, i'm trying to get arraylist (Tweet) to be read row by row to insert each of it's fields into dt. There is no error but when run in browser, each cell of the gridview shows 'DataExtraction.Tweet'.I'm not sure where to go from here.
I have a gridview that I bind on Page Load event.In the rowdatabound event I want to add a row to the gridview and bind it based on the value of the current record.The row is not being added. Is there a way to bind the extra row in the rowdatabound event?
Private Sub grdDocuments_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grdDocuments.RowDataBound If e.Row.RowType = DataControlRowType.DataRow Then Dim dt As DataTable Dim dv As DataView = grdDocuments.DataSource
