GridView Adding Additional Rows In Row Data Bound Event
Nov 1, 2012
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
[code]...

I've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code:
Dim _dt As System.Data.DataTable
_dt = _srvc.GetVinylShutters(0)
_dt.Rows.Add(_dt.NewRow)
grdShutters.DataSource = _dt
grdShutters.DataBind()
(_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code:
For Each col As DataControlField In grdShutters.Columns
Select Case col.HeaderText
Case "OrderID", _
"ShutterID", _
"ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.

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 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

$('#placeholder').setTemplateURL('JTemplates/Template.htm');
$('#placeholder').processTemplate(data.d);
}
like adding a table, ul and ui tag etc, I tried append without any success:
function Success(data, status) {
$('#placeholder').append('<table><tr><ul><ui>');
$('#placeholder').setTemplateURL('JTemplates/Template.htm');
$('#placeholder').processTemplate(data.d);

I have a page on which everything is loaded dynamically.
There is a Gridview (AutoGenerateColumns=true) and in the RowDataBound I check every column for a boolean datatype. If found I add a checkbox (autopostback=true) to the cell and register the CheckedChanged event.
The problem is, that I only get the CheckedChanged event, if I reload the grid in Page_Load:
protected void Page_Load(object sender, EventArgs e) {
LoadGrid();
}
But this is very expensive and causes that the db request will be executed twice. If I changed the code to what I want:
protected void Page_Load(object sender, EventArgs e) {
if (!this.IsPostBack)
loadGrid();
}
I get no CheckedChanged event.
Is there a possibility to get:
- Adding a Checkbox in RowDataBound
- Only "LoadGrid()" if it is no PostBack
- Getting the CheckedChanged event of the relevant row

I would like to know simple thing, If i'm adding additional information to UserProfile such as: Country, PhoneNumber etc'.. So, I added a Table In my DB (which also Got all Membership Provider tables...)
UserProfile, and added Stored Procedures for it for Insert / Update... I would like to know, If I need to create in Business Object a Class for Profile Only? (Cause the User is managed Already by the Membership Provider) And Create for it Also in Business Logic -> ProfileManager with Methods that will use the Stored Procedures to Update and Insert Details? Do I need to do it like this? Or there is another way? What's the right way doing it?
