Forms Data Controls :: Adding Rows To GridView During Runtime?
Dec 10, 2010
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'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 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 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.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
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.

Is it possible to add values from different database rows to a dropdownlist?
I'm currently trying to add both ItemSizeSmall and ItemSizeMedium, but through trial and error I can still only add one row from the database. I want the dropdownlist to display "Small" and "Medium" etc.
I guess my primary question is: How do I create a database with product size attributes?
I apologize if this thread should be in another forum, but if the dropdownlist can display two database rows I'll settle with that solution.
Could the database look like this:
table1: product
PK: productID
table2: productAttribute
PK: productID
PK: attributeValueID
table3: attributeValue
PK: attributeValueID
FK1: attributeNameID
table4: attribute
PK: attributeNameID
name
If this is right: How do I make the dropdownlist display the different sizes?

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 need to show 3 gridviews in a tab container (ajax).. which should refresh at same time.. what is the optimal way to get data from database for that can some one show a solution for this .
i need to design an application in asp.net using gridview custom control. the gridview will show hundreds of records using paging with checkboxes in every row. if the user checks 3 rows in first page of gridview which is showing 9 rows, those 3 rows should appear on top in the next gridview page and the page should display only 6 new records. ie 6+3=9 similarly if user checks 2 more rows, the next page should show 3+2 rows(from first 2 pages) on top and only 4 new rows ( 3+2+4=9)software developer

i am using the inbuilt database in VS08. I was trying to write code to query Gridview control to show only those rows whom i specify through my Query.
I searched for it and found some code which might work for External databases. But found no code for inbuilt database MS SQL Server provided in VS08.
Also there is no such method available for GridView1 object.

I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable
